Technical Field

The present invention relates generally to cooking appliances.

Background

Some cooking appliances (such as electric rice cooker) have the function of micro-pressure or negative pressure, so that food can be cooked in the micro-pressure or negative pressure environment, and a good cooking effect is achieved. Cooking appliances are generally sealed and pressure-relieved by the following two ways:

1. one is to seal the position of the air outlet blocked by the steel ball, and to release pressure when the steel ball leaves the air outlet, and to push the steel ball to block or leave the air outlet by the electromagnet;

2. when the electromagnet works, the air outlet is blocked by the silica gel piece under the drive of a certain mechanism, and a closed space is formed in the cooking utensil to realize sealing.

However, for the above-mentioned cooking utensil, when the electro-magnet ages or trouble, the iron core can not normally reset, leads to unable pressure release thereby influences normal uncapping. In addition, when the negative pressure is too big, reset force of reset mechanism is less after the electro-magnet outage, is insufficient to overcome inside and outside pressure differential, leads to the silica gel piece to be unable to separate with the gas outlet and can't the pressure release, can influence normal uncapping equally.

Accordingly, there is a need for a cooking appliance that at least partially solves the problems of the prior art.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present invention. It will be apparent that embodiments of the invention may be practiced without limitation to the specific details that are set forth by those skilled in the art.

The invention discloses a cooking utensil. Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, the cooking appliance includes a pot body 10 and a cover body 20. Although the drawings show only a part of the cooking appliance, it is understood that the pot body 10 may be generally constructed in the shape of a rounded rectangular parallelepiped, with the inner pot 11 disposed therein. The inner pot 11 is configured to be removably disposed in the pot body 10. For example, in one embodiment, a cylindrical inner pot accommodating portion may be provided in the pot body 10, and the inner pot 11 may be freely placed in or taken out from the inner pot accommodating portion. The removable arrangement allows the user to conveniently remove and clean the inner pan 11. Of course, in other embodiments, the inner pot 11 may be fixedly disposed in the pot body 10 in a non-removable manner. Heating means (not shown) for heating the inner pot 11 are also typically provided in the pot body 10.

The cover 20 is openably and closably provided on the pot body 10, and has a shape corresponding to the shape of the pot body 10, so that the pot body 10 can be conveniently covered. When the cover 20 is opened, the opening of the inner pot 11 is exposed, and a user can add food material to the inner pot 11 or take out cooked food from the inner pot 11. When the cover 20 is covered on the cooker body 10, it covers the inner pot 11 and forms a cooking space 12 with the inner pot 11. A sealing ring (not shown) is provided between the cover 20 and the inner pot 11, so that the cooking space 12 can maintain good sealability.

As shown in fig. 1, in the present embodiment, the lid body 20 includes three parts of a face cover 24, an inner liner 21, and a detachable cover 22. The liner 21 has high strength and can play a supporting role. A removable cover 22 is provided on the side of the liner 21 facing the inner pot 11, which can be removed from the liner 21 for easy cleaning. The cover 24 covers the outside of the liner 21, protects the liner 21 and parts provided thereon, and makes the cover 20 as a whole more attractive. Of course, in the embodiment not shown in the drawings, other embodiments of the cover 20 are also possible, for example, the cover 20 may be provided as a unitary integral structure.

In addition, the cooking appliance shown in the present invention is further provided with a pressure reducing device (not shown). The pressure reducing means serves to lower the pressure in the cooking space 12 below a predetermined pressure. For example, cooking space 12 may be evacuated to a pressure below atmospheric pressure. The state in which the pressure inside the cooking space 12 is lower than the atmospheric pressure may be referred to as a negative pressure state. Therefore, the cooking appliance can be an electric cooker, an electric pressure cooker and the like with a negative pressure function. The negative pressure environment helps to optimize the cooking process and preserve food. For example, when cooking rice, the cooking space 12 is kept in a negative pressure environment during the water absorption process of rice grains, so that rice and water can be mixed faster and better; in addition, the food which is not needed to be taken after cooking is stored in the cooking space 12 in the negative pressure environment, so that the deterioration speed of the food can be slowed down, and the food can keep good taste for a long time.

In one embodiment, the pressure relief device may include an air pump. The air inlet of the air pump is communicated with the cooking space 12 through an exhaust pipe made of silica gel, and the air outlet of the air pump can be communicated with the external environment of the cooking space 12, for example, directly communicated with the external atmosphere. When it is necessary to create a negative pressure environment in the cooking space 12, the air pump is manually activated by a control device or by a person to pump air, and the air in the cooking space 12 is discharged through the air pump and the air pump, wherein the pressure is reduced. A pressure measuring device may be provided to monitor the pressure in the cooking space 12, and when the pressure therein drops to a predetermined value, the air pump stops working, and a negative pressure environment is formed in the cooking space 12. Preferably, the pressure reducing device may further include a solenoid valve provided on an air flow path between the air pump and the cooking space 12 to control opening and closing of the air flow path. The solenoid valve turns on the air flow path when the air suction is completed, and cuts off the air flow path after the air suction is completed, so that the interior of the cooking space 12 is maintained in a negative pressure state.

When cooking space 12 is in a negative pressure state, atmospheric pressure acts on cover 20, and difficulties are encountered if it is desired to open the cover to perform an operation such as taking food stored in cooking space 12. Thus, a pressure relief assembly 30 is provided. Before the cover is opened, the pressure is released through the pressure release assembly 30, so that the inside of the cooking space 12 is restored to the normal pressure state, and the cover is conveniently opened. As shown in fig. 2, pressure relief assembly 30 may include a transmission 39, a seal 32, and a pressure relief button 40. Accordingly, the cover 20 is provided with a pressure release hole 23 communicating with the cooking space 12. The seal 32 is connected to the transmission 39 and is capable of sealing the pressure relief hole 23. The pressure release button 40 is provided on the upper surface of the cover 20, and is movable up and down between a home position and a pressure release position with respect to the cover 20. When the pressure release button 40 moves from the original position to the pressure release position, the pressure release button drives the sealing member 32 to be far away from the pressure release hole 23 through the transmission mechanism 39, so that pressure release is realized.

Wherein the pressure relief assembly 30 is disposed on the stronger liner 21. The detachable cover 22 is in direct contact with the cooking space 12, and thus the pressure release hole 23 is provided on the detachable cover 22. The pressure relief button 40 is preferably provided on the face cover 24, and the user can conveniently find and press the pressure relief button 40. Preferably, a spring 401 is provided between the pressure release button 40 and the face cover 24. The spring 401 biases the pressure relief button 40 toward the home position. Thus, the influence of the gravity of the pressure release button 40 on the lever 38 can be reduced, and misoperation can be avoided.

Specifically, the transmission mechanism 39 includes the relief lever 31 and the lever 38.

The pressure release lever 31 is vertically disposed, has two position states of an open position and a sealed position, and is movable up and down between the two positions. The seal 32 is connected to the pressure release lever 31 and is integrally movable with the pressure release lever 31. When the relief lever 31 is in the open position (the state shown in fig. 2 and 4), the seal 32 does not contact the relief hole 23. The cooking space 12 can now communicate with the outside through the pressure relief hole 23. And when the pressure release lever 31 is in the sealing position (the state shown in fig. 1 and 3), the sealing member 32 performs a sealing function as the pressure release lever 31 moves to the pressure release hole 23.

The lever 38 is disposed laterally and is pivotable in a vertical plane about a lever pivot axis 381. One end of the lever 38 is connected to the pressure release lever 31 and the other end is located below the pressure release button 40. As shown in fig. 2, when the pressure release button 40 moves to the pressure release position in the direction B, the pressure release button 40 pushes the lever 38 to pivot about the lever pivot shaft 381, and the one end of the lever 38 moves the pressure release lever 31 upward. That is, the pressure release lever 31 moves upward from the sealing position in the direction a while driving the sealing member 32 away from the pressure release hole 23, thereby realizing pressure release. Preferably, when the pressure release button 40 is moved to the pressure release position, the lever 38 can drive the pressure release lever 31 to move upward to the open position, so that the sealing member 32 is completely separated from the pressure release hole 23, and quick and complete pressure release is realized.

As shown in fig. 1, the upper end of the pressure release lever 31 is configured in a T-shape, and the end of the lever 38 corresponding to the pressure release lever 31 has a U-shaped groove therethrough. The pressure release lever 31 is nested within the U-shaped channel and the lever 38 is located below the T-shaped structure. Thus, when the end of the lever 38 moves upward, the lever 38 can drive the pressure release lever 31 upward due to the blocking action of the T-shaped structure. While the pressure release lever 31 does not move with the lever 38 when the end of the lever 38 moves downward. That is, the lever 38 can only move the pressure release lever 31 from the sealing position to the opening position, and cannot move the pressure release lever 31 from the opening position to the sealing position. So that the lever 38 can only play a role of pressure relief without affecting the transition of the cooking space 12 from the pressure relief state to the sealing state. Of course, it will be appreciated that in other embodiments the relief bar 31 may be integrally connected with the lever 38.

Preferably, the lever pivot shaft 381 may be spaced a smaller distance from the pressure relief button 40 than the lever pivot shaft 381 is spaced from the pressure relief lever 31, i.e., the fulcrum of the lever 38 is closer to the power end and further from the resistance end. Thus, in the free state, one end of the lever 38 connected to the pressure release lever 31 is sunk, and the other end corresponding to the pressure release button 40 is tilted upward. Thereby ensuring that the lever 38 does not affect the state of the pressure release rod 31 in the free state and avoiding the pressure release caused by the misoperation of the lever.

Preferably, as shown in fig. 3-5, the pressure relief assembly 30 further includes a power device 37 for driving the pressure relief lever 31 from the open position to the sealed position and securing the pressure relief lever 31 in the sealed position.

Preferably, the lower end of the pressure release lever 31 is provided with a lever seat 33. As shown in fig. 3 and 4, the outside of the rod seat 33 is provided with ribs extending perpendicular to the axial direction of the pressure release rod 31, and the seal 32 is connected to the pressure release rod 31 by being engaged with the ribs. Thereby, the sealing member 32 is connected to the end of the pressure release lever 31, and the structure of the cooking appliance can be made more compact. The rod seat 33 may be integrally formed with the main body of the pressure release rod 31, or may be separately manufactured and then connected to the main body of the pressure release rod 31 by means such as a snap-fit connection, a threaded connection, or the like.

Meanwhile, the pressure relief assembly 30 further includes a pressure relief cap 34 and a pressure relief spring 35. As shown in fig. 3 and 4, the pressure release cover 34 is sleeved on the pressure release rod 31. The pressure release spring 35 is located between the pressure release cover 34 and the lever seat 33. In order to keep the pressure release spring 35 stable, it is also sleeved on the pressure release rod 31. The power device 37 is configured to act on the pressure relief cover 34 to effect movement of and secure the pressure relief lever 31.

The purpose of the pressure release cover 34 and the pressure release spring 35 is that if the power device 37 directly acts on the pressure release lever 31, since the pressure release lever 31 and the power device 37 are of a rigid structure, and there is a manufacturing error in actual production, the travel distance of the pressure release lever 31 from the open position to the sealed position is easily made to be too large, so that the pressure release lever 31 is moved to the sealed position where the seal 32 completely seals the pressure release hole 23, and then the movement is continued. This may cause the seal 32 to excessively fit with the relief hole 23 or even protrude from the relief hole 23, resulting in a problem of poor sealing.

While the power device 37 indirectly drives the pressure release lever 31 through the pressure release cover 34 and the pressure release spring 35, when the pressure release lever 31 moves to the sealing position where the sealing member 32 completely seals the pressure release hole 23, if the power device 37 continues to act on the pressure release cover 34, part of the acting force is absorbed due to the buffering action of the pressure release spring 35, so that the pressure release lever 31 and the sealing member 32 can be ensured to be fixed at the position without excessive movement. Thereby ensuring the accuracy of sealing the relief aperture 23 with the relief assembly 30.

In order to keep the movement of the pressure release cover 34 and the pressure release lever 31 stable, a pressure release seat 36 is also provided. The pressure release cover 34 and the pressure release lever 31 are fixed together on the liner 21 by the pressure release seat 36 and are fastened by fasteners such as screws, so that the pressure release cover 34 and the pressure release lever 31 can only move up and down in the axial direction of the pressure release lever 31, while remaining fixed in other directions.

Fig. 5 shows a preferred embodiment of the power plant 37, which comprises a transmission 371, an electromagnet 372 and an electromagnetic spring 373. The transmission 371 is connected to the core 377 of the electromagnet 372. An electromagnetic spring 373 is disposed between the transmission 371 and the electromagnet 372. When the electromagnet 372 is operated, the iron core 377 is sucked, the transmission member 371 is driven to move toward the direction approaching the electromagnet 372, and the electromagnetic spring 373 is compressed. When the electromagnet 372 is de-energized, the iron core 377 is not attracted, and the elastic force of the electromagnetic spring 373 moves the transmission member 371 in a direction away from the electromagnet 372. Of course, it is also possible to provide the electromagnetic spring 373 on the side of the transmission member 371 remote from the electromagnet 372, and to cause the electromagnetic spring 373 to be stretched when the transmission member 371 is moved toward the electromagnet 372.

The transmission member 371 is used for transmitting the movement of the core 377 of the electromagnet 372 to the pressure release rod 31 and converting the movement into the movement of the pressure release rod 31. Specifically, the transmission member 371 is generally configured in an elongated shape, which includes a pressing portion 374 and a relief portion 375. The relief 375 is connected to the core 377. As shown in fig. 3 and 4, the transmission member 371 is located above the pressure release cover 34, and along the axial direction of the pressure release lever 31, the escape portion 375 is farther from the pressure release cover 34 than the pressing portion 374.

When the electromagnet 372 is powered off, the iron core 377 is in a free state, the transmission member 371 is far away from the electromagnet 372 under the action of the electromagnetic spring 373, and the avoiding portion 375 is aligned with the pressure release cover 34 along the axial direction of the pressure release rod 31. At this time, the transmission member 371 is located at the reset position and is not in contact with the pressure release cover 34, so that the pressure release lever 31 is located at the open position without being acted on by the power device 37. And when electromagnet 372 is energized, iron core 377 is attracted to drive member 371 against electromagnet 372 and pressing portion 374 is aligned with pressure relief cap 34 along the axial direction of pressure relief rod 31. At this time, the transmission member 371 is located at the in-place position, and the pressing portion 374 presses the pressure release cover 34 to move the pressure release lever 31 toward the sealing position, and fixes the pressure release lever 31 at the sealing position.

It will be appreciated that the transmission 371 may also be connected to the core 377 of the electromagnet 372 by a pressing portion 374. Thus, the position of drive member 371 when it is near electromagnet 372 should be the reset position and the position when drive member 371 is far from electromagnet 372 should be the home position.

Preferably, the transition between the relief portion 375 and the pressing portion 374 of the transmission member 371 is angled to facilitate the transfer of motion from the transmission member 371 to the pressure relief housing 34 during movement. Preferably, the transmission member 371 is provided with a through slot 376, and is sleeved on the pressure release rod 31 through the slot 376. In this way, the relative positions of the transmission piece 371 and the pressure release cover 34 can be ensured, so that the transmission is more reliable. Note that the length of the slot 376 should be greater than the distance that the transmission 371 moves between the reset and home positions, so as to avoid excessive contact between the transmission 371 and the pressure relief lever 31 as much as possible so as not to interfere with movement of the pressure relief lever 31.

Turning again to fig. 1 and 2, the cover 20 is also provided with a clasp 50. The clasp 50 is pivotally connected to the cover 20 by a clasp pivot shaft (not shown). Wherein the clasp gap axis is horizontally disposed so that clasp 50 can pivot in a vertical plane. The lower end of the clasp 50 is provided with a hooking part 501, and correspondingly, a clasp position is arranged on the pot body 10 at a position corresponding to the hooking part 501. When the cover 20 is covered on the cooker body 10, the hooking portion 501 can be hooked on the fastening position, so that the cover 20 and the cooker body 10 can be firmly covered. Preferably, torsion spring 502 is sleeved on the pivot shaft of the clasp. The torsion spring 502 biases the clasp 50 toward the position of hooking the pot body 10, so that the firmness of the cover 20 and the pot body 10 can be further ensured.

The end of the clasp 50 opposite the hooking portion 501 is disposed below the pressure release button 40. When the pressure release button 40 moves downward from the original position, it pushes the clasp 50 to pivot about the clasp pivot axis, disengaging the catch 501 from the catch on the pot 10. Since the pressure release is simultaneously performed during the movement of the pressure release button 40, the cover can be smoothly opened. Thus, the pressure relief and the uncovering can be completed through one operation, the method is convenient and quick, and the problem that the uncovering is difficult due to the fact that a user forgets to relieve the pressure and uncovers the cover can be avoided.

Preferably, as shown in fig. 2, the pressure release button 40 may be configured such that, during movement from the home position toward the pressure release position, the pressure release button 40 first contacts the lever 38 to effect pressure release, and then contacts the clasp 50 to effect uncapping. This ensures that a complete pressure release is achieved when the lid is opened.

The structure realizes the simultaneous operation of pressure relief and uncovering, combines the pressure relief and the uncovering into one action, is convenient and quick, and can avoid the problem that the user forgets to relieve the pressure, namely uncovers the cover easily.

According to the cooking utensil disclosed by the invention, the sealing element and the pressure relief hole can be forcedly separated to relieve pressure through the pressure relief button and the transmission mechanism, so that the pressure relief operation is simple, convenient and reliable. Even if the electromagnetic spring fails to cause the pressure release rod to be at the sealing position all the time, or when pressure release is needed in the electrifying process of the electromagnet, the forced pressure release can be realized through the transmission mechanism. And the pressure release button is arranged on the upper surface of the cover body, and can be operated in a downward pressing mode, so that the use of a user can be facilitated.
