真空吸尘器vacuum cleaner

本发明涉及适合家庭使用的真空吸尘器，特别涉及一种真空吸尘器，该吸尘器可解决由用于真空吸尘器的电动抽风机产生的各种问题。The present invention relates to a vacuum cleaner suitable for home use, and more particularly to a vacuum cleaner which can solve various problems caused by electric suction fans used in vacuum cleaners.

通用的真空吸尘器中，如尚待审批的日本专利申请第61-115529号中所公开的，电动抽风机容室是以密封分隔的方式限定在机壳内。由一个抽风机和一个电机组成的电动抽风机被平放在该容室中。通过一个隔音箱隔振式地支承电动抽风机，该隔音箱起限定电动抽风机容室的分隔壁的作用。准确地说，由隔音箱经一个橡胶的前隔振器在抽风机的外周边将其支承起来，而电机是由隔音箱经一个橡胶后隔振器支承的。进而在前橡胶隔振器上带有与隔音箱内壁面压紧接触的凸缘，以使隔音箱保持充分密封。In a general-purpose vacuum cleaner, as disclosed in the pending Japanese Patent Application No. 61-115529, an electric blower chamber is defined in a casing in a sealed manner. An electric exhaust fan consisting of an exhaust fan and a motor is placed flat in the chamber. The electric blower is supported in a vibration-insulated manner by a soundproof box which acts as a partition wall delimiting the chamber of the electric blower. To be precise, the soundproof box is supported on the outer periphery of the exhaust fan through a rubber front isolator, and the motor is supported by the soundproof box through a rubber rear vibration isolator. Furthermore, the front rubber vibration isolator is provided with a flange that presses and contacts the inner wall of the soundproof box, so that the soundproof box remains fully sealed.

考虑到上述先有技术的方案，电动抽风机的重量仅分别施加在前、后橡胶隔振器的下部。特别是前橡胶隔振器下部的一段凸缘受压更重并且会变形。另一方面，该前橡胶隔振器的上部的一段凸缘则脱离开隔音箱的内壁面。此外，当电动抽风机转动时，抽风机的上游空间形成负压，从而产生使前橡胶隔振器趋向于朝上游一侧移动的推力，也就是作用在与电动抽风机重量的推力方向相垂直方向的推力。这种推力造成隔音箱和前橡胶隔振器上部的凸缘段之间形成间隙。因此，上述先有技有这样一个问题，即由于前橡胶隔振器不可能获得充分的密封效果。Considering the above-mentioned prior art scheme, the weight of the electric blower is only applied to the lower parts of the front and rear rubber vibration isolators respectively. In particular, a section of the flange at the lower part of the front rubber isolator is more stressed and deformed. On the other hand, a section of flange on the top of the front rubber vibration isolator is separated from the inner wall surface of the soundproof box. In addition, when the electric exhaust fan rotates, negative pressure is formed in the upstream space of the exhaust fan, thereby generating a thrust that makes the front rubber vibration isolator tend to move toward the upstream side, that is, acting in a direction perpendicular to the thrust direction of the weight of the electric exhaust fan direction of thrust. This thrust creates a gap between the soundproof box and the flange segment on top of the front rubber isolator. Therefore, the above-mentioned prior art has a problem that it is impossible to obtain a sufficient sealing effect due to the front rubber isolator.

另外，上述先有技术的方案，组装时带凸缘的前橡胶隔振器是被用力装入隔音箱的。由于这样安排，很可能使凸缘的某处或多处变形和向上弯。因此，先有技术存在的问题是不能得到充分密封和隔振的效果。In addition, in the above prior art solution, the flanged front rubber vibration isolator is forcibly fitted into the soundproof box during assembly. Due to this arrangement, it is likely that one or more places of the flange will be deformed and bent upward. Therefore, there is a problem in the prior art that sufficient sealing and vibration isolation effects cannot be obtained.

再者，在先有技术中没有考虑到将电动抽风机装入机壳的方案。因此先有技术又存在难于将电动抽风机装入机壳的问题。另外，还有一个问题没有考虑过，即当采用大功率电动抽风机时，排放气流会导致高温。如果排放气流不断升温，令人担心的是会使隔音箱产生热变形。Furthermore, in the prior art, no consideration has been given to the scheme of packing the electric exhaust fan into the casing. Therefore there is the problem that the electric exhaust fan is difficult to be packed into the casing again in the prior art. In addition, there is another problem that has not been considered, that is, when a high-power electric exhaust fan is used, the exhaust airflow will cause high temperature. If the exhaust airflow continues to heat up, there is a concern that it will cause thermal deformation of the soundproof box.

鉴于上述问题的讨论，本发明的目的是提供一种真空吸尘器，该机能实现电动抽风机的充分隔振和充分的密封支承，容易将电动抽风机装入机壳，而且在采用大功率电动抽风机时，能适应防止隔音箱的热变形。In view of the discussion of the above problems, the purpose of the present invention is to provide a vacuum cleaner, which can realize sufficient vibration isolation and sufficient sealing support of the electric exhaust fan, and it is easy to install the electric exhaust fan into the casing. Machine, can adapt to prevent thermal deformation of the soundproof box.

实现上述目的的真空吸尘器包括一个以密封分隔方式确定的机壳，一个集尘室，一条与集尘室相联的联系通道，一个与联系通道连通的电动抽风机容室，一条与电机抽风机容室连通的排气通道，一个与排气通道连通的排气室，以及一个由抽风机和电机组成的电动抽风机，该电动抽风机是以抽风机位于电机之下的方式竖直设置在电动抽风机容室内，其中限定电动抽风机容室的分隔壁是由相对于机壳整体加工而成，并且将电动抽风机的抽风机罩住的管形凸缘组成，一个与机壳分开单独制作并且将电动抽风机的电机罩住的隔音箱，以此设置使隔音箱被装到管形凸缘上。The vacuum cleaner for achieving the above purpose includes a casing determined by a sealed partition, a dust collection chamber, a communication channel connected with the dust collection room, an electric exhaust fan chamber connected with the communication channel, and a motor exhaust fan chamber. An exhaust passage communicated with the chamber, an exhaust chamber communicated with the exhaust passage, and an electric exhaust fan composed of an exhaust fan and a motor, the electric exhaust fan is vertically arranged in a manner that the exhaust fan is located under the motor In the chamber of the electric exhaust fan, the partition wall defining the chamber of the electric exhaust fan is composed of a tubular flange that is integrally processed relative to the casing and covers the exhaust fan of the electric exhaust fan. A soundproof box is fabricated and houses the motor of the electric extractor fan, in such an arrangement that the soundproof box is attached to the tubular flange.

在按上面安排的真空吸尘器中，电动抽风机是按抽风机位于电机下方的方式竖直地设置在电动抽风机容室中的。照这样布局，由电动抽风机的重量产生的推力和由电动抽风机转动导致发生负压所造成的吸力便均匀地施加在一种弹性件的整个区域上，该弹性件用于以密封和隔振的形式支承电动抽风机的抽风机。推力和吸力作用于同一方向，从而可以得到强推力。因此，弹性件与电动抽风机容室的分隔壁之间不会形成间隙，由于该弹性件面能达到充分密封效果。In the vacuum cleaner arranged as above, the electric blower is vertically arranged in the electric blower housing chamber in such a manner that the blower is located below the motor. Arranged in this way, the thrust force generated by the weight of the electric exhaust fan and the suction force caused by the negative pressure generated by the rotation of the electric exhaust fan are uniformly applied to the entire area of an elastic member for sealing and insulating The exhaust fan that supports the electric exhaust fan in the form of vibration. The thrust and the suction act in the same direction, so that a strong thrust can be obtained. Therefore, no gap will be formed between the elastic member and the partition wall of the electric blower chamber, because the surface of the elastic member can achieve a sufficient sealing effect.

另外，本方案的特点在于电动抽风机容室的分隔壁是由与机壳整体制成的管形凸缘构成，隔音箱是分离开机壳的，该隔音箱适于装配到管形凸缘上。本方案中是这样进行装配的，先将电动抽风机插入管形凸缘，而后将隔音箱安装固定在该管形凸缘上。因此，能便于将电动抽风机装入电动抽风机容室。In addition, the feature of this solution is that the partition wall of the electric exhaust fan chamber is composed of a tubular flange integrally formed with the casing, and the soundproof box is separated from the casing, and the soundproof box is suitable for being assembled to the tubular flange superior. In this scheme, the assembly is carried out in such a way that the electric exhaust fan is inserted into the tubular flange first, and then the soundproof box is installed and fixed on the tubular flange. Therefore, it is convenient to install the electric blower into the electric blower chamber.

进而，本方案的特点在于隔音箱被安装到管形凸缘上。考虑到这样安排若使用大功率电动抽风机会导致电动抽风机的排放气流温度升得很高，因此仅以耐热材料制作隔音箱。这样做既不必以耐热材料制作整个机壳，还能防止电动抽风机容室的分隔壁变形。Furthermore, the solution is characterized in that the soundproof box is mounted on the tubular flange. Considering that if such an arrangement uses a high-power electric exhaust fan, the temperature of the exhaust air flow of the electric exhaust fan will rise very high, so only heat-resistant materials are used to make the soundproof box. In this way, it is not necessary to make the whole casing with heat-resistant materials, and it can also prevent the partition wall of the electric exhaust fan chamber from being deformed.

此外，由于垂直设置电动抽风机，由电动抽风机重量产生的推力和由于电动抽风机转动产生负压而形成的推力，这两种推力可施加在弹性元件上。因此，可以获得充分的密封效果，使被加工的弹性元件没有令人担心的凸缘上弯的情况。In addition, since the electric blower is arranged vertically, the thrust generated by the weight of the electric blower and the thrust formed by the negative pressure generated by the rotation of the electric blower can be applied to the elastic member. Therefore, a sufficient sealing effect can be obtained, so that the processed elastic member does not have the worrying situation of flange upturning.

按上述方案，当电动抽风机10转动时，空气经吸口30进入过滤袋35并穿过过滤袋35和集尘盒34。空气又经联系通道5流进电动抽风机容室6，并且由导向肋板17引导顺利流入抽风机组件10a。流出抽风机组件10a的空气冷却电机组件10b的内部，随后，膨胀并流出，成为排放气流流到围绕电机10b外周的空间。由电动抽风机10产生风声噪音和滚珠轴承的旋转噪音均被隔音箱12隔绝掉。从电动抽风机容室6流出的排放气进入排气通道7并且在其内被压缩。该排放气沿排气通道7向下流，随后，流进消音通道8并在其内膨胀。进入消音通道8的排放气流被若干个整流叶片18分成多股气流，这些股气流同时被整流叶片18改变流向180度。排放气流进入排气室9并且经排气窗3a被排放到机壳1的外部。在消音通道8里被分成多股的气流又互相合在一起，而后该气流进入排气室9并在其内膨胀。According to the above scheme, when the electric blower 10 rotates, the air enters thefilter bag 35 through thesuction port 30 and passes through thefilter bag 35 and thedust box 34 . The air flows into theelectric blower chamber 6 through the communication channel 5, and is guided by the guide ribs 17 to smoothly flow into theblower assembly 10a. The air flowing out of theblower assembly 10a cools the interior of themotor assembly 10b, and then expands and flows out as a discharge airflow to the space surrounding the periphery of themotor 10b. The wind noise generated by the electric exhaust fan 10 and the rotation noise of the ball bearing are all isolated by thesoundproof box 12 . The exhaust gas flowing out of theelectric blower chamber 6 enters theexhaust passage 7 and is compressed therein. The exhaust gas flows downward along theexhaust passage 7, and then, flows into the muffler passage 8 and expands therein. The exhaust airflow entering the muffler passage 8 is divided into multiple airflows by several rectification vanes 18, and these airflows are changed by the rectification vanes 18 to flow 180 degrees at the same time. The exhaust airflow enters theexhaust chamber 9 and is exhausted to the outside of the cabinet 1 through the exhaust window 3a. The air streams which are divided into several strands in the sound-absorbing channel 8 are joined together again, and then the air stream enters theexhaust chamber 9 and expands therein.

由于在空气流经排气通道7，消音通道8和排气室9过程中被反复压缩和膨胀，因此降低了由电动抽风机10的转动造成的噪声音量。通过吸音材料15进一步降低噪声音量。Since the air is repeatedly compressed and expanded when it flows through theexhaust passage 7, the muffler passage 8 and theexhaust chamber 9, the noise volume caused by the rotation of the electric exhaust fan 10 is reduced. The noise volume is further reduced by thesound absorbing material 15 .

穿过集尘盒34的微细灰尘和由电动抽风机10的转动产生的刷损粉末之类的微细灰尘被细尘过滤器25滤掉，不会从电动抽风机容室6，排气通道7，消音通道8和排气室9漏到机壳1的内部和外部。因此，机壳1内部避免被弄脏，而且经排气窗3a流出的只是清洁空气。The fine dust passing through thedust box 34 and the brush damage powder produced by the rotation of the electric exhaust fan 10 are filtered out by thefine dust filter 25, and can not be discharged from the electricexhaust fan chamber 6, theexhaust passage 7 , The muffler channel 8 and theexhaust chamber 9 leak to the inside and outside of the casing 1. Therefore, the inside of the cabinet 1 is prevented from being soiled, and only clean air flows out through the exhaust window 3a.

电动抽风机10转动所产生的噪声通过包括隔音箱12和上机壳2在内的双层壁板被隔绝。于是，在机壳1上方位置上所能听到的噪声相当低。由于利用下机壳3的底面使消音通道8构成U形，因此容易把消音通道8做得长些，而且不必增加机壳1的尺寸。The noise generated by the rotation of the electric exhaust fan 10 is insulated by the double wall panels including thesoundproof box 12 and theupper casing 2 . Therefore, the noise that can be heard at the position above the cabinet 1 is relatively low. Since the bottom surface of thelower casing 3 is utilized to make the sound-absorbing passage 8 form a U-shape, it is easy to make the sound-absorbing passage 8 longer without increasing the size of the casing 1.

当采用大功率电动抽风机10而且电机10b内的冷却气流量因集尘盒34或过滤袋35堵塞面减少时，流出电机10b的排放气便会导致高温。所以，隔音箱12被加热量很高温度。然而，由于隔音籍12是用耐高温材料制成的，因此可以防止隔音箱12的受热变形。由于隔音箱12是分离机壳1单独构成的而且按此安排单独安装到管形凸缘11上，因此按此连接，只有隔音箱12用面高热材料制作，而机壳1可用一般的廉价合成树脂制成。When adopting high-power electric blower 10 and the cooling air flow rate in themotor 10b is reduced because ofdust box 34 orfilter bag 35 clogged surface, the discharge gas that flows outmotor 10b just can cause high temperature. Therefore, thesoundproof box 12 is heated to a high temperature. However, since thesoundproof box 12 is made of a high temperature resistant material, the thermal deformation of thesoundproof box 12 can be prevented. Because thesoundproof box 12 is formed separately from the casing 1 and is separately installed on the tubular flange 11 according to this arrangement, so according to this connection, only thesoundproof box 12 is made of high-heat materials, and the casing 1 can be synthesized with general cheap materials. Made of resin.

由于放入电动抽风机容室6的电动抽风机10是抽风机10a位于电机组件10b的下方，因此电动抽风机10的重量和由电动抽风机10的转动导致负压所产生的推力都作用在同一方向并施加于第一弹性件20的整个区域。因此，第一弹性件20随着强而均匀的推力紧靠在装配段21上。这样就提供了稳定可靠的密封和产生隔振效果。Because the electric blower 10 that puts into theelectric blower chamber 6 is that theblower 10a is positioned at the below of themotor assembly 10b, so the weight of the electric blower 10 and the thrust produced by the negative pressure caused by the rotation of the electric blower 10 all act on The same direction and applied to the entire area of the firstelastic member 20 . Therefore, the firstelastic member 20 abuts against theassembly section 21 with a strong and uniform pushing force. This provides a stable and reliable seal and produces vibration isolation.

电动抽风机10装入下机壳3是按下面的方式进行的。即，首先预先将第一弹性件20，第二弹性件22和吸音盖24装到电动抽风机10上。而后，将电动抽风机10插入管形凸缘11，则第一弹性件20便被装到装配段21上了。然后，把隔音箱12盖到电动抽风机10上，并用螺钉13和13a固定到管形凸缘11上。这样，就完成了电动抽风机10的装入。不一定非要预先把第一和第二弹性件20和22及吸音盖24装到电动抽风机10上。也就是说，可以这样把电动抽风机10装入下机壳3；先将第一弹性件20装到管形凸缘11里的装配段21上，然后把电动抽风机10装进第一弹性件20；随后再把吸音盖24和第二弹性件22装到电动抽风机10上，最后将隔音箱12盖在电动抽风机10上。Electric exhaust fan 10 is packed intolower casing 3 and is carried out in the following manner. That is, firstly, the firstelastic member 20 , the secondelastic member 22 and the sound-absorbingcover 24 are installed on the electric exhaust fan 10 in advance. Then, the electric blower 10 is inserted into the tubular flange 11, and the firstelastic member 20 is installed on theassembly section 21. Then, thesoundproof box 12 is put on the electric blower 10, and fixed to the tubular flange 11 with the screws 13 and 13a. In this way, the loading of the electric blower 10 is completed. It is not necessary to install the first and secondelastic members 20 and 22 and the sound-absorbingcover 24 on the electric blower 10 in advance. That is to say, the electric exhaust fan 10 can be packed into thelower casing 3 in this way; first the firstelastic member 20 is installed on theassembly section 21 in the tubular flange 11, and then the electric exhaust fan 10 is packed into the firstelastic Part 20; then the sound-absorbingcover 24 and the secondelastic member 22 are installed on the electric exhaust fan 10, and finally thesoundproof box 12 is covered on the electric exhaust fan 10.

图8是频率特性的示意图，标示出根据所述实施例的真空吸尘器中由于装入隔音箱12而实现的消音效果。噪声是在上机壳2上方一米的位置测量的。a线代表先有技术，而b线表示上述实施例。从频率特性可以理解上述实施例的消音效果与先有技术相比得到了相当可观的改善。FIG. 8 is a graph of frequency characteristics, indicating the sound attenuation effect achieved by incorporating thesoundproof box 12 in the vacuum cleaner according to the embodiment. The noise was measured at a position one meter above theupper cabinet 2 . Line a represents the prior art, while line b represents the embodiment described above. It can be understood from the frequency characteristics that the noise reduction effect of the above embodiment is considerably improved compared with the prior art.

虽然上述实施例中联系通道5相对短些，但其长度可以增加。相反，联系通道5可以仅用一个通孔来加工成，通过该孔集尘室4和电动抽风机容室6相互连通。另外，如果采用小功率电动抽风机则电动抽风机的转动噪音很低，那末可以不用设消音通道8。在这种情况下，排气通道7直接与排气室9连通。Although the communication channel 5 is relatively short in the above embodiments, its length can be increased. On the contrary, the communication channel 5 can be processed with only one through hole, through which the dust collection chamber 4 and theelectric blower chamber 6 communicate with each other. In addition, if the low-power electric exhaust fan is adopted, the rotational noise of the electric exhaust fan is very low, so the sound-absorbing passage 8 may not be established. In this case, theexhaust channel 7 communicates directly with theexhaust chamber 9 .

在上述实施例中，空气可以经联系通道5电动抽风机容室6，排气通道7和消音通道8能使空气从集尘室4流到排气室，还能经排气窗3a排放到机壳1的外部且不会漏入机身壳体1内的空间。相应地除了排气窗3a外，还设置细尘过滤器25，这一措施既能保证除掉从集尘室4流进排气室9的微细灰尘，还能除掉像由电动抽风机10产生的刷损粉末那样的微细灰尘。从而可以进行更清洁的吸尘操作。In the above-mentioned embodiment, the air can pass through the connecting channel 5electric blower chamber 6, theexhaust channel 7 and the sound-absorbing channel 8 can make the air flow from the dust collection chamber 4 to the exhaust chamber, and can also be discharged to the exhaust chamber through the exhaust window 3a. outside of the casing 1 and will not leak into the space inside the casing 1 of the fuselage. Correspondingly, in addition to the exhaust window 3a, afine dust filter 25 is also set. This measure can both ensure that the fine dust flowing into theexhaust chamber 9 from the dust collection chamber 4 is removed, and it can also remove dust as generated by the electric exhaust fan 10. Fine dust like brush damage powder generated. The result is a cleaner vacuuming operation.
