Problems solved by technology

[0004] In the process of realizing and using the existing electric pressure cooker, the inventor found that there are at least the following problems in the prior art: first, the structure of the tearable pressure relief sheet cannot be reused, and the installation and fixing method of the pressure relief sheet is comparatively difficult. Complicated and inconvenient to maintain
Second, the plastic deformation of the pot lid has a large pressure relief area, resulting in a large range of steam injection during pressure relief, and the resulting destructive force is relatively large, and there are still certain potential safety hazards

no. 1 example

[0050] The present invention provides a non-self-resetting pressure relief electric pressure cooker, please refer to Figure 1-Figure 9, the electric pressure cooker includes a pot body 100, a pot cover 200 and an inner container 300, the inner container 300 is located in the pot body 100, the pot cover 200 is located on the pot body 100 and is connected with the inner container 300 An inner cooking cavity 400 is formed. When the food needs to be cooked, the user puts the food in the inner pot 300 .

[0051] The pot cover 200 includes a lower cover 210 and an upper cover. In this embodiment, the lower cover 210 is an inner cover, and the lower cover 210 is provided with a second sealing ring 218, and the second sealing ring 218 is used for In order to seal the gap between the lower cover 210 and the inner tank 300, the upper cover is located above the lower cover 210. In this embodiment, the upper cover includes a lock ring 222, a lining 221 and a face cover. The inner linin...

[0066] Figure 15 It is a perspective view of the lower cover of the third embodiment of the present invention, Figure 15 structure with Figure 3a The structures are similar, so the same reference numerals represent the same components. The main difference between this embodiment and the first embodiment is the shape of the elastic jumper and its fixing method.

[0067] In this example, see Figure 15-Figure 17 , the elastic jumping member is not the disc spring 430, the elastic jumping member is a jumping shrapnel 611, and the jumping shrapnel 611 is elongated and arched in the middle. In this embodiment, the inner side of the sealing ring wall 440 is not provided with the first mounting column 211, and the outer periphery of the sealing ring wall 440 is provided with a fourth mounting column 612, and the fourth mounting column 612 is formed by the lower cover. 210 is formed extending away from the inner cooking cavity 400 . One end of the jumping elastic piece 611 is a...

Abstract

The invention provides a non-self-resetting and pressure-relief electric pressure cooker, which includes a pot body, a pot cover and an inner pot, the inner pot is located in the pot body, and the pot cover and the inner pot form a cooking cavity. That is, the cooking cavity is provided with an opening communicating with the outside world, the opening is provided with a sealing pressure plate for direct or indirect sealing, and the sealing pressure plate is connected with an elastic jumper, when the pressure in the cooking cavity When the temperature is 120kpa-350kpa, the sealing pressing plate can press the elastic jumper to jump so that the cooking cavity communicates with the outside world and maintains the communication with the outside world. The elastic jumping part of the electric pressure cooker of the present invention will not reset after jumping, so that cooking is safe for the user.

Description

technical field [0001] The invention relates to a kitchen cooking appliance, in particular to a non-self-resetting electric pressure cooker. Background technique [0002] In order to ensure the cooking safety of the electric pressure cooker, the existing electric pressure cooker is generally equipped with a pressure relief device. When the pressure in the electric pressure cooker exceeds the set pressure relief pressure, the pressure relief device will be activated to release the high-pressure steam in the electric pressure cooker. Reduce pot pressure for safe cooking. The existing pressure relief device generally adopts a self-resetting pressure relief valve. When the pressure in the electric pressure cooker drops below the pressure relief pressure, the pressure relief device will automatically reset, so that the pressure in the pressure cooker continues to rise. This self-resetting pressure relief valve does not meet the industry standard of the current electric pressure ...
