Embodiment 1

[0028] According to an embodiment of the present invention, an embodiment of a cooking pressure control method of a cooking appliance is provided. It should be noted that the steps shown in the flow charts of the drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0029] Optionally, the cooking appliance includes a cooking cavity with an exhaust port and a pressure limiting valve for sealing the exhaust port. The pressure limiting valve includes an internal valve sealed on the exhaust port with pressure and superimposed a certain pressure An outer valve acting on an inner valve.

[0030]Specifically, the above-mentioned cooking appliance can be an electric pressure cooker, and the above-mentioned pressure limiting valve can be a double-stage pressure limit...

Embodiment 2

[0062] According to an embodiment of the present invention, an embodiment of a cooking pressure control device for a cooking appliance is provided.

[0063] Optionally, the cooking appliance includes a cooking cavity with an exhaust port and a pressure limiting valve for sealing the exhaust port. The pressure limiting valve includes an internal valve sealed on the exhaust port with pressure and superimposed a certain pressure An outer valve acting on an inner valve.

[0064] Specifically, the above-mentioned cooking appliance can be an electric pressure cooker, and the above-mentioned pressure limiting valve can be a double-stage pressure limiting valve, wherein the pressure of the inner valve is 30KPA, and the pressure of the outer valve is 70KPA, that is, when the pressure in the cooking cavity reaches 30KPA When the pressure in the cooking cavity lifts the internal valve, the internal valve no longer acts on the exhaust port, but due to the effect of the external valve, the e...

Embodiment 3

[0077] According to an embodiment of the present invention, an embodiment of a cooking appliance is provided.

[0078] image 3 is a schematic diagram of a cooking utensil according to an embodiment of the present invention, such as image 3 As shown, the cooking appliance includes: a cooking cavity with an exhaust port, a pressure limiting valve 10 for blocking the exhaust port, a detection device 20, a timer 30 and a controller 40, wherein the pressure limiting valve 10 includes: The internal valve 12 that is blocked by pressure on the exhaust port and the external valve 14 that superimposes a certain pressure on the internal valve; the detection device 20 is used to detect the temperature or pressure in the cooking cavity; the timer 30 is connected with the detection device for when the temperature Or when the pressure reaches the first preset value, start counting; the controller 40 is connected with the pressure limiting valve, the detection device and the timer, and is ...

Abstract

The invention discloses a cooking utensil and a cooking pressure control method and device thereof. Wherein, the cooking utensil includes a cooking cavity with an exhaust port and a pressure limiting valve for sealing the exhaust port. The pressure limiting valve includes an inner valve sealed on the exhaust port with pressure and an outer valve acting on the inner valve with a superimposed certain pressure. The cooking pressure control method includes: controlling the heating of the cooking utensil so that the temperature or pressure in the cooking cavity reaches a first preset value; when the temperature or pressure reaches the first preset value, timing is started and the outer valve is opened , so that the internal valve acts on the exhaust port alone, wherein, if the temperature or pressure exceeds the first preset value, the pressure in the cooking cavity will automatically overcome the pressure of the internal valve, so that the cooking appliance will be exhausted according to the first exhaust method; when the timing When the time reaches the first preset time, the outer valve is released, so that the inner valve and the outer valve act on the exhaust port at the same time. The invention solves the technical problem that the pressure limiting valve in the prior art is single-stage controlled, resulting in slow cooking speed and poor cooking effect.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular, to a cooking appliance and an improvement of a cooking pressure control method and device thereof. Background technique [0002] For existing cooking appliances, such as electric pressure cookers, a pressure limiting valve will be installed to control the pressure inside the cooking appliance. The pressure limiting valve is a single-stage pressure control. When the pressure inside the cooking appliance exceeds the preset pressure , the pressure limiting valve is pushed open by the pressure inside the cooking utensil, and the pressure limiting valve is exhausted, or the opening or closing of the pressure limiting valve is controlled by a driving device such as a motor or a solenoid valve. [0003] However, the existing cooking utensils are exhausted through a single-stage control pressure limiting valve. The cooking utensils cannot be continuously heated during the hea...
