Description

cooking utensils

technical field

The utility model relates to the technical field of kitchen appliances, in particular to a structural improvement of the installation method of a pressure limiting valve of a cooking appliance.

Background technique

As a household appliance, electric pressure cooker is more and more favored by consumers because of its convenient use and fast cooking.

The pressure-limiting valve is usually set on the lid of the electric pressure cooker. The setting of the pressure-limiting valve can ensure that the pot body can reach sufficient cooking pressure and cooking temperature when the electric pressure cooker is working; It is convenient for users to take the ingredients in the pot.

In the prior art, at least a part of the pressure-limiting valve will be protruded from the upper surface of the pot cover, so that when the user accidentally touches the pressure-limiting valve, the steam in the pot will be released from the pressure-limiting valve, which may cause burns. Therefore, the design structure of the existing electric pressure cooker is unreasonable, and there is a problem of poor safety in use.

Utility model content

The main purpose of the present invention is to provide a cooking utensil to solve the problems of unreasonable design and structure of electric pressure cookers in the prior art and poor use safety.

In order to achieve the above purpose, the present invention provides a cooking utensil, comprising a pot body and a pot cover arranged on the pot body. The pot cover includes: an inner pot cover and an exhaust pipe, and the exhaust pipe is arranged on the inner pot cover; the face cover, the face cover cover is arranged on the inner pot cover, and a accommodating space is formed between the face cover and the inner pot cover ;Pressure-limiting valve mechanism, the pressure-limiting valve mechanism is connected with the inner pot cover or the surface cover and located in the accommodating space, and the pressure-limiting valve mechanism is used to resist and cooperate with the exhaust pipe to maintain the pressure in the pot or release the pressure in the pot .

By applying the technical scheme of the present invention, by optimizing the structure of the pot cover of the cooking utensil, the pressure-limiting valve mechanism that resists and cooperates with the exhaust pipe is arranged between the lower surface of the surface cover and the upper surface of the inner pot cover to form a accommodating space so that the entire pressure limiting valve mechanism is in a position lower than the face cover, that is, to ensure that the pressure limiting valve mechanism does not protrude from the face cover. In this way, while ensuring the reliable operation of the pressure limiting valve mechanism, it also effectively avoids The user accidentally touches the pressure-limiting valve mechanism during the use of the cooking utensil, thereby greatly reducing the possibility of the user being scalded by the steam released by the pressure-limiting valve mechanism, thereby improving the safety and practicality of the cooking utensil. sex.

Further, the pressure-limiting valve mechanism includes: a support frame, which is connected to the upper surface of the inner pot cover and is located at the position of the nozzle of the exhaust pipe; a pressure-limiting valve, which can be raised and lowered on the support frame and Press the nozzle of the exhaust pipe. In this way, the support frame plays the role of installing and supporting the pressure-limiting valve. Since the overall length of the exhaust pipe on the inner pot cover is shortened, the pressure-limiting valve presses the nozzle of the exhaust pipe under the action of its own weight, so that the inner pot is in the In the pressure-raising state or the pressure-holding state, when the pressure in the pot overcomes the weight of the pressure-limiting valve, the pressure-limiting valve can be lifted to avoid danger due to excessive pressure in the pot. When the pressure in the pot needs to be released , the pressure limiting valve can also be driven to be lifted by means of external components.

Further, the support frame includes a support plate and a guide cylinder, wherein the support plate is U-shaped, two ends of the U-shaped support plate are respectively fixedly connected to the upper surface of the inner pot cover, and the guide cylinder is arranged on the support plate to limit the pressure.

In this way, the guide cylinder plays a role in the lifting and guiding of the pressure-limiting valve. During the lifting and lowering of the pressure-limiting valve, the inner wall of the guide cylinder can fit with the outer wall of the pressure-limiting valve to limit the movement path of the pressure-limiting valve and ensure that The working stability of the pressure limiting valve mechanism.

Further, at least a part of the upper surface of the exhaust pipe is recessed to form a pressure limiting groove, and the pressing end face of the pressure limiting valve facing the exhaust pipe is in contact with the groove wall surface of the pressure limiting groove. In this way, the contact area between the pressure limiting valve and the exhaust pipe can be increased, so as to improve the sealing reliability of the pressure limiting valve to the nozzle of the exhaust pipe.

Further, the groove wall surface of the pressure limiting groove and the pressing end surface of the pressure limiting valve are partial surfaces of a spherical surface or an ellipsoid surface. The exhaust pipe and the pressure-limiting valve of this structure are not only convenient for batch processing, but also have a high-precision matching effect, which greatly improves the sealing effect of the connection between the two.

Further, the face cover includes a face cover body and an air guide cylinder, the face cover body is provided with an exhaust port, the exhaust port is arranged opposite to the pressure limiting valve mechanism, and the air guide cylinder is penetrated at the exhaust port and connected with the face cover body, The air guide tube extends toward one side of the inner pot cover and abuts with the upper surface of the inner pot cover, and the air guide tube covers the pressure limiting valve mechanism in its interior. In this way, the air guide tube plays a guiding role for the steam discharged from the nozzle of the exhaust pipe, so that the steam is discharged from the air guide tube in the shortest path, so as to ensure that the cooking utensil can be stably and reliably depressurized.

Further, the pot cover also includes a steam cover, the steam cover is detachably covered on the air guide cylinder, and an exhaust through hole is opened on the steam cover. The setting of the steam cover prevents a lot of steam from swarming out from the top of the air guide tube, that is to say, the steam cover acts as a stopper for the steam and plays a role in planning the way of the pot cover, avoiding the swarming out. The steam burns the user and improves the practicability of the cooking utensil.

Further, the inner wall surface of the air guide cylinder is protrudingly provided with a buckle, and the steam cover includes a cover body, a clamping hook and a handle, wherein the exhaust through hole is opened on the cover body, and the clamping hook is protrudingly arranged under the cover body.

In this way, the stability of the steam cover installed on the air guide cylinder can be ensured, and after the steam cover is removed, the interior of the air guide cylinder can be easily cleaned, which greatly improves the convenience of cleaning the cooking utensils. The handle arrangement is convenient for grasping the steam cap.

Further, there are multiple exhaust through holes, and the multiple exhaust through holes are arranged at intervals around the outer circumference of the handle. In this way, the steam released at the steam cover can be regularized, and the steam cover can also be ensured to meet the release requirements of the amount of steam, so that the pressure relief operation of the cooking appliance can be performed reliably.

Further, the distance H between the lower surface of the steam cover and the top end of the pressure limiting valve mechanism is greater than or equal to 3 mm and less than or equal to 5 mm.
