一种具有泄压功能的电压力锅An electric pressure cooker with pressure relief function

技术领域technical field

本发明涉及电压力锅技术领域，特别是涉及一种具有泄压功能的电压力锅。The invention relates to the technical field of electric pressure cookers, in particular to an electric pressure cooker with a pressure relief function.

背景技术Background technique

随着人们生活节奏的加快，厨房烹饪器具需要满足人们对快捷方便的需求。现有的电压力锅具有烹饪快速、烹饪温度高、烹饪食物营养流失少、食物口感好、省电等众多优点，已经成为家庭厨房中必不可少的烹饪器具。然而，传统的电压力锅烹饪工作结束后，因为锅内有高压，用户不能马上打开锅盖，而必须拨开或按下泄压阀进行排气降压，或者让锅内食物自然冷却，等到锅内压力降低到常压后才能开盖取出食物，因在快速烹饪美食后不能快速打开锅盖而不能立即享受美食，造成等待时间过长，这给用户带来很大的不便。With the acceleration of people's life rhythm, kitchen cooking utensils need to meet people's needs for quickness and convenience. The existing electric pressure cooker has many advantages, such as fast cooking, high cooking temperature, less nutrient loss of cooked food, good food taste, power saving, etc., and has become an indispensable cooking appliance in home kitchens. However, after the traditional electric pressure cooker is finished cooking, the user cannot open the lid immediately because of the high pressure in the pot, but must open or press the pressure relief valve to exhaust and reduce pressure, or let the food in the pot cool down naturally, and wait until the pot is inside. After the pressure is reduced to normal pressure, the lid can be opened to take out the food. Because the lid of the pot cannot be opened quickly after cooking the food quickly and the food cannot be enjoyed immediately, the waiting time is too long, which brings great inconvenience to the user.

为了解决传统电压力锅存在的不能快速开盖的技术问题，行内提出了一些技术解决方案：一是通过散热风扇吹出的冷却风在烹饪结束后对锅胆或锅盖进行冷却，但是在实际应用过程中发现，风冷效果并不明显，用户仍然不能很快地打开锅盖；二是通过锅盖上安装的排气装置在烹饪结束后主动排出锅内气体，在用户拨开或按下泄压阀排气降压的过程中，如果锅内烹饪的是流体食物，则锅内的流体食物容易被高压蒸汽从排气口处喷出，给用户造成危险，同时也会污染锅体内外表面和环境，带来清洁问题。In order to solve the technical problem that the traditional electric pressure cooker cannot open the lid quickly, the industry has proposed some technical solutions: First, the cooling air blown by the cooling fan cools the inner pot or lid after cooking, but in the actual application process It is found that the air cooling effect is not obvious, and the user still cannot open the lid quickly; the second is to actively discharge the gas in the pot after the cooking is completed through the exhaust device installed on the lid, and the user opens or presses the pressure relief valve. During the process of exhausting and depressurizing, if the liquid food is cooked in the pot, the liquid food in the pot will be easily ejected from the exhaust port by the high-pressure steam, which will cause danger to the user, and will also pollute the inner and outer surfaces of the pot and the environment. , causing cleaning problems.

因此亟需一种新的具有泄压功能的电压力锅。Therefore, there is an urgent need for a new electric pressure cooker with a pressure relief function.

本发明实施例提供的一种具有泄压功能的电压力锅100的工作原理为：以储水箱311内的冷却水为冷却介质，通过射流泵32加压冷却水为射流冲击提供压力，高压冷却水通过射流管312输送到喷嘴33，通过圆形或窄缝型喷嘴33直接喷射到锅盖20内盖23表面进行冷却，射流冲击冷却由于冷却水直接接触到需要冷却的表面，高动量冲击产生很强的冷却效果，冷却水快速从内盖23吸收热量，快速降低内盖23温度，加快锅内高温高压蒸汽向冷却水散热，进而实现锅内快速降温泄压。射流冲击冷却内盖23表面平均换热系数高达10000W/m2，是普通水冷平均换热系数的10倍左右。射流管312由多排矩形管路3121b、环形管路3122或圆形平板管路3123构成，布置多个射流喷嘴33，保证射流喷射冷却水覆盖锅盖20内盖23表面，增大射流冷却水与内盖23的换热面积，增强内盖23的散热能力。采用射流冲击冷却可以实现电压力锅100快速泄压，缩短泄压时间，比普通水冷泄压时间缩短30％以上；同时，由于射流冲击冷却换热能力强，在冷却水温度较高的情况下，仍然可以保证很强的冷却效果，因此，射流冲击所需冷却水水量比普通水冷减少30％以上，可以减小储水箱311和电压力锅100整机体积和重量。The working principle of theelectric pressure cooker 100 with a pressure relief function provided by the embodiment of the present invention is as follows: the cooling water in thewater storage tank 311 is used as the cooling medium, the cooling water is pressurized by thejet pump 32 to provide pressure for the jet impact, and the high-pressure cooling water It is sent to thenozzle 33 through thejet pipe 312, and is directly sprayed to the surface of theinner cover 23 of thepot cover 20 through the circular or narrow-slot nozzle 33 for cooling. Because the cooling water directly contacts the surface to be cooled, the high-momentum impact produces a very high momentum. Strong cooling effect, the cooling water quickly absorbs heat from theinner cover 23, quickly reduces the temperature of theinner cover 23, and accelerates the heat dissipation of the high-temperature and high-pressure steam in the pot to the cooling water, thereby achieving rapid cooling and pressure relief in the pot. The average heat transfer coefficient of the surface of the jet impact coolinginner cover 23 is as high as 10000W/m2, which is about 10 times the average heat transfer coefficient of ordinary water cooling. Thejet tube 312 is composed of multiple rows ofrectangular pipelines 3121b,annular pipelines 3122 or circularflat pipelines 3123, and a plurality ofjet nozzles 33 are arranged to ensure that the jet cooling water covers the surface of theinner cover 23 of thepot cover 20 and increases the jet cooling water. The heat exchange area with theinner cover 23 enhances the heat dissipation capability of theinner cover 23 . The use of jet impact cooling can realize rapid pressure relief of theelectric pressure cooker 100, shorten the pressure relief time, and shorten the pressure relief time by more than 30% compared with ordinary water cooling. Strong cooling effect can still be ensured, therefore, the cooling water volume required by the jet impact is reduced by more than 30% compared with ordinary water cooling, which can reduce the volume and weight of thewater storage tank 311 and theelectric pressure cooker 100.
