技术领域Technical Field
本发明涉及烹饪设备，具体地涉及一种电烤箱。The invention relates to cooking equipment, in particular to an electric oven.
背景技术Background technique
电烤箱是利用电热元件发出的热辐射烤制食物的厨房电器，可以用于加工面包、蛋挞、小饼干等食物。An electric oven is a kitchen appliance that uses heat radiation from electric heating elements to bake food. It can be used to process foods such as bread, egg tarts, and biscuits.
通常地，电烤箱具有由顶板、底板、左侧板、右侧板、背板等通过无缝焊接或螺纹连接而成的烹饪腔体，由此限定具有预定空间的烹饪腔室。左侧板和右侧板的内侧壁连接有凸台结构，以便支撑烤盘或烤架。烹饪腔体连接有例如为不锈钢发热管或石英发热管的电热元件，该电热元件延伸至烹饪腔室内，以通过发出热辐射的方式烤制放置于烤盘或烤架上的食物。Generally, an electric oven has a cooking cavity formed by seamlessly welding or threading a top plate, a bottom plate, a left plate, a right plate, a back plate, etc., thereby defining a cooking cavity with a predetermined space. The inner side walls of the left plate and the right plate are connected with a boss structure to support a baking tray or a grill. The cooking cavity is connected with an electric heating element such as a stainless steel heating tube or a quartz heating tube, which extends into the cooking cavity to bake food placed on the baking tray or the grill by emitting heat radiation.
然而，上述现有技术存在缺陷。一方面，电热元件延伸至烹饪腔室内，距离被烤制的食物距离较近，难以向食物各部分均匀地发热，容易导致烤焦或碳化；另一方面，在烤制过程中，产生的水汽和油烟与电热元件接触并附着，在长时间使用后容易导致电热元件产生热量难以向食物散发甚至损坏，影响其可靠性。此外，传统电烤箱中的烹饪腔体在连接部位具有死角，难以充分清洁。However, the above-mentioned prior art has defects. On the one hand, the electric heating element extends into the cooking cavity and is close to the food being baked, making it difficult to evenly heat all parts of the food, which can easily lead to burning or carbonization. On the other hand, during the baking process, the water vapor and oil smoke generated come into contact with and adhere to the electric heating element, which can easily cause the heat generated by the electric heating element to be difficult to dissipate to the food or even be damaged after long-term use, affecting its reliability. In addition, the cooking cavity in the traditional electric oven has a dead angle at the connection part, which is difficult to fully clean.

以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下、左、右”通常是指参考附图所示的上、下、左、右；“内、外”是指相对于各部件本身的轮廓的内、外。In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to up, down, left, right as shown in the reference drawings; "inside and outside" refer to inside and outside relative to the outline of each component itself.
参照图1至图3所示，根据本发明一种优选实施方式的电烤箱，包括烹饪腔体1、炉门2和发热管3等。其中，烹饪腔体1具有由导热材料(如铸铝)制成的顶板11、底板12、左侧板13和右侧板14(以及随后所述的背板15)。该烹饪腔体1设置有取放食物的开口16，通常设置于朝向使用者的一侧。炉门2能够在打开位置和关闭位置之间运动，以封闭或打开所述开口16。其中，在关闭位置，炉门2与烹饪腔体1限定有烹饪腔室17；在打开位置，使用者可以通过开口16将食物放置于该烹饪腔室17中。As shown in Figures 1 to 3, an electric oven according to a preferred embodiment of the present invention includes a cooking cavity 1, an oven door 2, a heating tube 3, etc. The cooking cavity 1 has a top plate 11, a bottom plate 12, a left plate 13, and a right plate 14 (and the back plate 15 described later) made of a heat-conducting material (such as cast aluminum). The cooking cavity 1 is provided with an opening 16 for taking food in and out, which is usually arranged on the side facing the user. The oven door 2 can move between an open position and a closed position to close or open the opening 16. In the closed position, the oven door 2 and the cooking cavity 1 define a cooking cavity 17; in the open position, the user can place food in the cooking cavity 17 through the opening 16.
在图示优选实施方式中，顶板11、底板12、左侧板13和右侧板14上分别形成有向烹饪腔室17凹陷的发热管槽18，发热管3设置于该发热管槽18内，并能够通过烹饪腔体1(即其顶板11、底板12、左侧板13和右侧板14等)向烹饪腔室17及其中的食物传递热量。In the preferred embodiment shown in the figure, a heating tube groove 18 recessed toward the cooking cavity 17 is formed on the top plate 11, the bottom plate 12, the left plate 13 and the right plate 14 respectively. The heating tube 3 is arranged in the heating tube groove 18 and can transfer heat to the cooking cavity 17 and the food therein through the cooking cavity 1 (i.e., its top plate 11, the bottom plate 12, the left plate 13 and the right plate 14, etc.).
由此，发热管3产生的热量辐射至烹饪腔体1，进而在整个烹饪腔体1的各处具有基本相同的温度，从而均匀加热烹饪腔室17内的食物，避免受热不均导致的烤焦或碳化问题。并且，由于发热管3布置与烹饪腔室17外，在烤制过程中不会受到水汽和油烟的影响，具有安全、可靠等优点。尤其是，通过形成容纳发热管3的发热管槽18，可以避免发热管3占用烹饪腔体1外侧的过多空间，便于如控制元件、隔热元件等的布置，由此避免因发热管3外置导致体积过大等问题，并且能够提高发热管3向烹饪腔体1的热传导效率。Thus, the heat generated by the heating tube 3 is radiated to the cooking cavity 1, and then the temperature is basically the same everywhere in the entire cooking cavity 1, so that the food in the cooking cavity 17 is evenly heated to avoid the problem of burning or carbonization caused by uneven heating. In addition, since the heating tube 3 is arranged outside the cooking cavity 17, it will not be affected by water vapor and oil smoke during the baking process, and has the advantages of safety and reliability. In particular, by forming a heating tube groove 18 to accommodate the heating tube 3, it can be avoided that the heating tube 3 occupies too much space outside the cooking cavity 1, which is convenient for the arrangement of control elements, insulation elements, etc., thereby avoiding the problem of excessive volume due to the external placement of the heating tube 3, and can improve the heat conduction efficiency of the heating tube 3 to the cooking cavity 1.
在本发明中，由于发热管3产生的热量并不直接地辐射至食物上，而是经过烹饪腔体1后均匀地加热，由此可以均匀地烤制食物。为此，发热管可以仅布置在顶板11、底板12、左侧板13和右侧板14中的一部分的外侧，例如，仅在左侧板13和右侧板14上形成发热管槽18。发热管3的数量可以根据所需烤箱功率和单个发热管3的功率进行匹配设置。In the present invention, since the heat generated by the heating tube 3 is not directly radiated to the food, but is evenly heated after passing through the cooking cavity 1, the food can be evenly baked. To this end, the heating tube can be arranged only on the outside of a part of the top plate 11, the bottom plate 12, the left plate 13 and the right plate 14, for example, the heating tube groove 18 is formed only on the left plate 13 and the right plate 14. The number of heating tubes 3 can be matched and set according to the required oven power and the power of a single heating tube 3.
本发明采用的发热管可以为不锈钢发热管或石英发热管，并根据需要适当布置。通常地，发热管3呈具有圆柱截面的条形形状，以便在端部连接至电源。其中，为了充分利用发热管3产生的热量，该发热管3可以与相应的烹饪腔体1壁面平行布置。例如，对应于水平布置的顶板11，其发热管槽18内的发热管3亦在水平方向延伸，由此该发热管3各管段部分产生的热量能够较大程度地传递至顶板11，以提高烹饪效率。The heating tube used in the present invention can be a stainless steel heating tube or a quartz heating tube, and can be arranged appropriately as needed. Generally, the heating tube 3 is in the shape of a strip with a cylindrical cross section so that it can be connected to a power source at the end. In order to make full use of the heat generated by the heating tube 3, the heating tube 3 can be arranged parallel to the wall of the corresponding cooking cavity 1. For example, corresponding to the horizontally arranged top plate 11, the heating tube 3 in the heating tube groove 18 also extends in the horizontal direction, so that the heat generated by each section of the heating tube 3 can be transferred to the top plate 11 to a greater extent to improve the cooking efficiency.
在一种优选实施方式中，左侧板13和右侧板14上的发热管槽18沿前后方向(即从炉门2向背板15方向)水平延伸，并且/或者，顶板11和底板12上的发热管槽18沿左右方向延伸，即沿垂直于左侧板13和右侧板14的方向延伸。顶板11、底板12、左侧板13和右侧板14上可以根据需要设置一个或多个发热管槽18，优选为设置不少于两个，以便提高加热效率。其中，将顶板11和底板12上的发热管槽18设置为沿左右方向延伸能够便于使得连接导线主要地布置烹饪腔体1两侧，避免电烤箱高度过高导致搬运困难等问题。In a preferred embodiment, the heating tube grooves 18 on the left side plate 13 and the right side plate 14 extend horizontally in the front-to-back direction (i.e., from the oven door 2 to the back plate 15), and/or, the heating tube grooves 18 on the top plate 11 and the bottom plate 12 extend in the left-to-right direction, i.e., extend in a direction perpendicular to the left side plate 13 and the right side plate 14. One or more heating tube grooves 18 can be provided on the top plate 11, the bottom plate 12, the left side plate 13 and the right side plate 14 as needed, preferably at least two, so as to improve the heating efficiency. Among them, setting the heating tube grooves 18 on the top plate 11 and the bottom plate 12 to extend in the left-to-right direction can facilitate the arrangement of the connecting wires mainly on both sides of the cooking cavity 1, avoiding the problem that the electric oven is too high and causes difficulty in carrying.
进一步地，左侧板13和右侧板14上的发热管槽18可以作为烤盘6和烤架7的承重导轨，由此无需额外地连接支撑结构，便于清洁。此处，发热管槽18可以具有U型截面，不仅可以避免在烹饪腔室17内形成死角，还能够对烤盘6和烤架7提供稳固的支撑作用。Furthermore, the heating pipe grooves 18 on the left side plate 13 and the right side plate 14 can serve as load-bearing guide rails for the grill pan 6 and the grill 7, thereby eliminating the need for additional support structures and facilitating cleaning. Here, the heating pipe grooves 18 can have a U-shaped cross-section, which can not only avoid forming a dead angle in the cooking chamber 17, but also provide a stable support for the grill pan 6 and the grill 7.
在本发明一种较为优选的实施方式中，烹饪腔体1还具有背板15，该背板15与处于关闭位置的炉门2相对。其中，包括该背板15在内的烹饪腔体1为由铸铝压铸成型的一体化结构，由此具有较高的刚度和良好的导热性能。特别是，通过形成为一体化结构，可以避免因具有连接部位而产生的死角，便于充分清洁，保证烹饪卫生。In a preferred embodiment of the present invention, the cooking cavity 1 further comprises a back plate 15, which is opposite to the oven door 2 in the closed position. The cooking cavity 1 including the back plate 15 is an integrated structure formed by die-casting of cast aluminum, thus having high rigidity and good thermal conductivity. In particular, by forming an integrated structure, dead angles caused by the connection parts can be avoided, which is convenient for full cleaning and ensures cooking hygiene.
其中，可以使得顶板11、底板12、左侧板13、右侧板14和背板15中彼此相接的部分形成为弧形过渡结构19。例如，在左侧板13与顶板11和底板12相接的位置，形成为弧形过渡结构19，由此具有较好的压铸工艺性，并能够方便地清洁。The portions of the top plate 11, the bottom plate 12, the left plate 13, the right plate 14 and the back plate 15 that are connected to each other can be formed into an arc-shaped transition structure 19. For example, the position where the left plate 13 is connected to the top plate 11 and the bottom plate 12 is formed into an arc-shaped transition structure 19, thereby having better die-casting processability and being easy to clean.
本发明的电烤箱还可以设置其他辅助性功能部件或结构。参照图2所示，该电烤箱设置有外罩4，罩设于烹饪腔体1外侧，其上形成有散热孔41。该外罩4能够对烹饪腔体1实施隔离，以避免意外接触导致的烫伤。The electric oven of the present invention may also be provided with other auxiliary functional components or structures. Referring to FIG2 , the electric oven is provided with an outer cover 4, which is provided outside the cooking cavity 1 and has heat dissipation holes 41 formed thereon. The outer cover 4 can isolate the cooking cavity 1 to avoid burns caused by accidental contact.
对应于炉门2所在的一侧，还可以设置控制面板5，该控制面板5上具有旋钮51、按钮52、显示屏53等，以控制或显示电烤箱的启停、加热温度等参数和状态。A control panel 5 may be provided on the side corresponding to the oven door 2. The control panel 5 has a knob 51, a button 52, a display screen 53, etc., to control or display parameters and states such as the start and stop and heating temperature of the electric oven.
本发明的电烤箱还可以具有温控器(未示出)，用于根据烹饪腔室17内的温度控制发热管3的通电状态或发热功率等，从而以适宜的温度烤制烹饪腔室17内的食物。The electric oven of the present invention may also have a temperature controller (not shown) for controlling the power-on state or heating power of the heating tube 3 according to the temperature in the cooking cavity 17, so as to bake the food in the cooking cavity 17 at a suitable temperature.
