Embodiment 1

[0036] like figure 2 and image 3 As shown, the electric rice cooker of the present embodiment includes a face cover 1, an inner cover 2, a motor 4, a steam valve seat 9 and a blade 6. The inner cover 2 is installed under the surface cover 1, and the surface cover 1 is provided with an exhaust hole 11, and the lower part of the surface cover 1 is provided with an annular retaining rib 12 protruding toward the direction of the inner cover 2 around the exhaust hole 11, and the inner cover 2 corresponds to A steam hole 21 is provided at the exhaust hole 11 , and a surface cover sealing ring 3 is provided between the annular retaining rib 12 and the inner cover 2 .

[0037] like figure 2 As shown, the upper end of the above-mentioned steam valve seat 9 is open, fastened under the inner cover 2, covering the steam hole 21 and the through hole 22 on the inner cover 2, and a sealing rib is provided at the joint between the steam valve seat 9 and the inner cover 2 7 to seal and f...

Embodiment 2

[0042] like Figure 4 As shown, the electric rice cooker of the present embodiment includes a face cover 1 , an inner cover 2 , a motor 4 , a cover plate 13 and blades 6 . The inner cover 2 is installed under the surface cover 1, and the surface cover 1 is provided with an exhaust hole 11, and the lower part of the surface cover 1 is provided with an annular retaining rib 12 protruding toward the direction of the inner cover 2 around the exhaust hole. A steam hole 22 is provided at the air hole, and a cover sealing ring 3 is provided between the annular retaining rib 12 and the inner cover 2 .

[0043] The motor 4 is installed between the surface cover 1 and the inner cover 2. Specifically, the inner cover 2 is provided with a through hole adjacent to the steam hole, the motor 4 is fixed above the inner cover 2, and the motor shaft 41 of the motor 4 passes through the through hole downward. The hole is rigidly connected with the connector 5, and the connector 5 is fixedly con...

Embodiment 3

[0047] like Figure 5 As shown, the rice cooker provided in this embodiment is substantially the same as that in Embodiment 2, the only difference being that the connector 5 in this embodiment is a plunger connector, and the blade 6 is fixed on the connector 5 through a ball plunger 8 . When the motor 4 is working, the motor shaft 41 drives the blade 6 to rotate through the connector 5, thereby forming a local negative pressure space.

Abstract

The invention provides a rice cooker having a foam overflow preventing function. The rice cooker has an axially sealed steam passage provided with a negative pressure generation device in the position corresponding to a steam inlet hole. Also provided is a method for preventing foam overflow, which comprises forming an axially sealed steam passage and generating a negative pressure at the position of the steam passage corresponding to the steam inlet hole. With the invention, a negative pressure generation device is arranged in a steam flowing passage of the cooker body, and rapid suctioning is carried out so that the steam in the cooker body has no time to supplement the space where gas is suctioned by the device, to form, nearby the negative pressure generation device, a local low pressure space with a local pressure lower than the internal pressure inside the cooker body, so as to physically avoid rice water foam overflow during rice cooking and porridge cooking processes of the rice cooker.

Description

technical field [0001] The invention relates to an electric rice cooker, which has the function of preventing or eliminating foam overflow; the invention also relates to a method for preventing or eliminating foam overflow in the cooking process of the electric rice cooker. Background technique [0002] When the rice cooker is cooking rice and porridge, a large amount of rice soup foam will be generated inside the rice cooker. If there is no control on the product, these rice soup foams will be discharged to the outside of the pot along the steam channel, which will cause trouble for product cleaning and overall safety performance. [0003] The method that solves rice soup to overflow at present mainly contains the following several. One method is to increase the staggered ribs in the steam channel (such as inside the steam valve) to increase the length of the entire movement track of the rice soup foam from the inside of the pot to the contact with the air outside the pot,...
