Description

TECHNICAL FIELD

[0001] The present application relates to the field of kitchen appliances, in particular to a cooking appliance with anti-leakage function. BACKGROUND

[0002] Compared with the traditional heating mode (electric heating disc or electromagnetic induction heating), the steam heating has better heat uniformity, which can solve the problems of uneven heating and easy burning of the pot in the traditional heating mode, and therefore the steam heating mode has gradually been paid attention to in recent years. A known steam heating type cooking appliance comprises a pot, a steam draining assembly, an inner cover and an outer cover. The inner cover is placed in the pot, and the outer cover is arranged outside the inner cover. Water is added into the pot. After the water in the pot is boiled, the air holes on the top of the inner cover can squeeze the water bubbles generated by the boiling water, and the generated steam enters the steam draining assembly to cook the food.

[0003] During the use of the user, the inner cover may be missed. Although the machine can work normally after the inner cover is missed, the water bubbles generated by the boiling water during the cooking process enter the steam draining assembly, which leads to poor cooking effect and large humidity of the food at the bottom of the steam draining assembly, thereby affecting the user experience. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a cooking appliance with anti-leakage function which can provide an alarm when the inner cover is not placed.

[0005] To solve the above technical problems, the present application adopts the following technical scheme: a cooking appliance with anti-leakage function, comprising a pot, a steam draining assembly, a detection device and a cover assembly. The cover assembly comprises an inner cover and an outer cover. The inner cover is placed in the pot. The steam draining assembly is located above the inner cover. The cover assembly divides the pot into a first cooking cavity and a second cooking cavity. The first cooking cavity is located outside the second cooking cavity. The detection device is used to detect the liquid state of the first cooking cavity and / or the second cooking cavity. The outer cover is provided with a sealing member. When the inner cover and the outer cover are placed in the pot, the bottom of the second cooking cavity is in communication with the first cooking cavity, so that the liquid in the first cooking cavity can flow into the second cooking cavity. When the inner cover is not placed in the pot, the bottom of the outer cover is sealed between the sealing member and the bottom wall of the pot, so as to block the flow of liquid between the first cooking cavity and the second cooking cavity.

[0006] In the above cooking appliance with anti-leakage function, the bottom of the inner cover is provided with a first flange extending outward. When the inner cover and the outer cover are placed in the pot, the first flange is supported between the sealing member and the bottom wall of the pot, so as to communicate the bottom of the second cooking cavity with the first cooking cavity.

[0007] In the cooking utensil with the leakage prevention assembly, the first flange comprises a flange body, an upper support part arranged on an upper surface of the flange body and a lower support part arranged on a lower surface of the flange body, the upper support part supports the sealing member, the lower support part is supported on the bottom wall of the inner pot, and the first liquid flow channel is formed between the flange body and the bottom wall of the inner pot.

[0008] In the cooking utensil with the leakage prevention assembly, the lower support part comprises a plurality of lower bosses which are distributed along the bottom surface of the flange body in a circumferential direction, and the upper support part comprises a plurality of upper bosses which are distributed along the upper surface of the flange body in a circumferential direction.

[0009] In the cooking utensil with the leakage prevention assembly, the accommodation space is formed between the inner cover and the outer cover, the second liquid flow channel is formed between the flange body and the sealing member, and the second liquid flow channel communicates the accommodation space and the first cooking cavity.

[0010] In the cooking utensil with the leakage prevention assembly, the sealing member comprises a ring-shaped body and a sealing lip which extends downward and outward from the ring-shaped body, and the sealing lip is abutted against the bottom wall of the inner pot.

[0011] In the cooking utensil with the leakage prevention assembly, the bottom of the outer cover is provided with a second flange which extends outward, and the ring-shaped body is arranged on the second flange.

[0012] In the cooking utensil with the leakage prevention assembly, the detection device is a liquid level sensor, the liquid level sensor is arranged on the side wall of the inner pot, and the position of the liquid level sensor is higher than the bottom of the second cooking cavity.

[0013] In the cooking utensil with the leakage prevention assembly, the outer cover and the condensation assembly are integrally formed, or the outer cover and the condensation assembly are separately formed, and the upper end of the outer cover is sealingly connected with the bottom wall of the condensation assembly.

[0014] In the cooking utensil with the leakage prevention assembly, the cooking utensil further comprises a gas supply device which supplies gas to the first cooking cavity to pressurize the first cooking cavity, and the liquid in the first cooking cavity flows into the second cooking cavity under pressure.

[0015] The cooking utensil with the leakage prevention assembly has the following advantages:

[0016] The cooking utensil comprises a pot, a steaming component, a detection device and a cover assembly. The cover assembly comprises an inner cover and an outer cover. The inner cover is placed in the pot. The steaming component is above the inner cover. The cover assembly divides the pot into a first cooking cavity and a second cooking cavity. The first cooking cavity is outside the second cooking cavity. The detection device detects the liquid state of the first cooking cavity and / or the second cooking cavity. The outer cover is provided with a sealing element. When the inner cover and the outer cover are placed in the pot, the bottom of the second cooking cavity is communicated with the first cooking cavity, so that the liquid in the first cooking cavity can flow into the second cooking cavity. When the inner cover is not placed in the pot, the bottom of the outer cover is sealed with the bottom wall of the pot by the sealing element, so as to block the flow of liquid between the first cooking cavity and the second cooking cavity. In the scheme, the sealing element is arranged on the outer cover. When the inner cover is placed, the inner cover will lift the outer cover, so as to ensure that the water in the first cooking cavity can enter the second cooking cavity, and the cooking utensil can work normally. If the inner cover is not placed, the sealing element at the bottom of the outer cover will directly contact the bottom wall of the pot, so that the water in the outer cover is isolated from the water in the pot. When the utensil body is heated, the water level in the pot will not change, so that the detection device can detect it and send an alarm information in time to remind the user that the inner cover has not been placed, thereby improving the user experience.

[0017] In a further scheme, the bottom of the inner cover is provided with a first flange extending outward. When the inner cover and the outer cover are placed in the pot, the first flange is supported between the sealing element and the bottom wall of the pot, so as to communicate the bottom of the second cooking cavity with the first cooking cavity. The first flange extending outward is arranged at the bottom of the inner cover, so as to outwardly support the sealing element arranged on the outer cover, thereby preventing the sealing element from contacting the bottom wall of the pot, and leaving space for the communication between the first cooking cavity and the second cooking cavity, so that the water in the first cooking cavity can enter the second cooking cavity.

[0018] In a further scheme, the first flange comprises a flange body, an upper support portion arranged on the upper surface of the flange body, and a lower support portion arranged on the lower surface of the flange body. The upper support portion supports the sealing element, and the lower support portion supports the bottom wall of the pot. The flange body and the bottom wall of the pot form a first liquid flow channel. The upper support portion can support the sealing element of the outer cover as far as possible, so as to open the channel width between the first cooking cavity and the second cooking cavity, and can also communicate the inner cover and the outer cover with the first cooking cavity, so that the accumulated water between the inner cover and the outer cover can flow back to the first cooking cavity. The lower support portion avoids the bottom surface of the inner cover from closely contacting the bottom wall of the pot, so as to leave a sufficient gap between the bottom surface of the inner cover and the bottom wall of the pot, thereby ensuring that the water in the first cooking cavity can smoothly flow into the second cooking cavity.

[0019] In a further aspect, the lower support portion comprises a plurality of lower protrusions spaced along the bottom surface of the flange body, and the upper support portion comprises a plurality of upper protrusions spaced along the upper surface of the flange body. The upper and lower protrusions are spaced to avoid the inner cover from being in close contact with the sealing element and the bottom wall of the inner pot, and to leave sufficient space to ensure the communication of the chambers.

[0020] In a further aspect, a receiving space is formed between the inner cover and the outer cover, and a second liquid flow channel is formed between the flange body and the sealing element, the second liquid flow channel communicating the receiving space and the first cooking chamber. The receiving space allows the water generated when the water vapor with bubbles produced by the inner cover is broken to be deposited in the receiving space, so that the water is separated from the water vapor. The deposited water returns to the first cooking chamber through the second liquid flow channel. The second liquid flow channel prevents the water in the receiving space from overflowing into the steam draining assembly, and ensures that the receiving space functions normally.

[0021] In a further aspect, the sealing element comprises a ring-shaped body and a sealing lip extending downward and outward from the ring-shaped body, the sealing lip abutting against the bottom wall of the inner pot. The ring-shaped body supports and shapes the sealing element to ensure a fixed shape of the sealing element. The downwardly extending sealing lip mainly functions as a sealing element, and can be closely attached to the bottom wall of the inner pot when in contact with the bottom wall, thereby achieving a good sealing effect and ensuring that the water in the outer cover is isolated from the water in the inner pot.

[0022] In a further aspect, the bottom of the outer cover is provided with a second flange extending outward, and the ring-shaped body is mounted on the second flange. The second flange facilitates the fixing of the ring-shaped body of the sealing element, reduces the use of fixing elements or sealing glue, and makes the installation and fixing more convenient.

[0023] In a further aspect, the detection device is a liquid level sensor, and the liquid level sensor is mounted on the side wall of the inner pot. The position of the liquid level sensor is higher than the bottom of the second cooking chamber. When the food needs to be soaked, there is sufficient water below the liquid level sensor to supplement the water, so that the amount of water is sufficient to cover the food.

[0024] In a further aspect, the outer cover and the steam draining assembly are integrally formed, or the outer cover and the steam draining assembly are separately formed, and the upper end of the outer cover is sealingly connected to the bottom wall of the steam draining assembly. These two arrangements of the outer cover and the steam draining assembly ensure the sealing property of the outer cover and the steam draining assembly, so that the steam produced by the inner cover can completely enter the steam draining assembly.

[0025] Further, the first cooking cavity is provided with a gas supply device for supplying gas and pressurizing, and the liquid in the first cooking cavity is pressurized to flow into the second cooking cavity, so that the gas supply device can provide pressure in the pot body, water is pressurized into the steam draining assembly before cooking food to soak the food, and water can be supplemented into the steam draining assembly in time when the food needs to be soaked again.

[0051] Embodiment one

[0052] As shown in Figure 1 , Figure 2 , the leak-proof cooking appliance includes an appliance body 100 and a cover body 200, the appliance body 100 includes a shell, an inner cavity is arranged in the shell, the cover body 200 and the shell are rotationally connected, and the cover body 200 is used for sealing the inner cavity when the cooking appliance is working. The appliance body 100 includes a kettle 110, a steaming assembly 120, a cover assembly, the cover assembly includes an inner cover 130 and an outer cover 140, a heating device 180 is arranged at the bottom of the inner cavity, the kettle 110 is embedded in the inner cavity above the heating device 180, the heating device 180 is used for heating water in the kettle 110, and a gas supply device 170 is further arranged in the inner cavity, the gas supply device 170 can adopt a gas pump, the gas pump is communicated with the kettle 110 through a gas pipe, the water level in the kettle 110 can be controlled by pressurizing the kettle 110 through the gas pump. A detection device is fixed on the kettle 110, the liquid state of the first cooking cavity and / or the second cooking cavity is detected through the detection device; the detection device can be a liquid level sensor 150, the liquid level in the kettle 110 can be sensed through the liquid level sensor 150, in order to better set the liquid level sensor 150 and reduce the probability that the liquid level sensor 150 is impacted by food in the kettle 110, a through hole 116 is opened on the side wall of the kettle 110, the head of the liquid level sensor 150 extends into the kettle 110 through the through hole 116, and the tail of the liquid level sensor 150 is located outside the kettle 110 and is connected with a wire to transmit a signal to a control system. Further, in order to prevent water from flowing out between the through hole 116 of the kettle 110 and the liquid level sensor 150, a sealing sleeve 151 is sleeved on the liquid level sensor 150, the outer ring of the sealing sleeve 151 is in interference fit with the through hole 116 of the kettle 110, the sealing sleeve 151 is made of a flexible sealing material such as rubber or silica gel, so as to improve the sealing performance of the installation position of the liquid level sensor 150 in the kettle 110. The detection device can also be other sensors such as a temperature sensor, which can identify whether the cooking appliance is leak-proof by sensing the temperature change of the liquid. The detection device can detect the liquid level change of the first cooking cavity, and can also detect the liquid level change of the second cooking cavity.

[0053] In some alternative embodiments, the inner pot is the appliance body, the cover is arranged on the steaming and draining assembly, the cover assembly is arranged on the inner side of the inner pot, and the rest of the arrangement remains unchanged.

[0054] The cover assembly and the inner pot form a first liquid flow channel connecting the first cooking cavity and the second cooking cavity, so that the liquid in the first cooking cavity can flow into the second cooking cavity through the first liquid flow channel, and the liquid in the second cooking cavity can also flow into the first cooking cavity through the first liquid flow channel. Specifically, the first liquid flow channel is formed between the inner cover and the inner pot.

[0055] As shown in Figure 2 The outer cover 140 is in a cylindrical shape, the top of the outer cover 140 is fixedly connected with the bottom wall of the steaming and draining assembly 120, and the two can be integrally formed, or the outer cover 140 and the steaming and draining assembly 120 are separately formed, the upper end of the outer cover 140 is sealingly connected with the bottom wall of the steaming and draining assembly 120, for example, the upper end of the outer cover 140 and the bottom wall of the steaming and draining assembly 120 are welded together, so that the outer cover 140 and the steaming and draining assembly 120 are connected into an integral whole, which is convenient for taking and placing during use and reduces the operation steps during use. Moreover, the top of the outer cover 140 and the bottom of the steaming and draining assembly 120 are provided with a communicating steam inlet 121, which facilitates the steam to enter the steaming and draining assembly 120 to cook the food in the steaming and draining assembly 120.

[0056] The bottom of the outer cover 140 is provided with a sealing member 160, which includes an annular body 161 and a sealing lip 162 extending downward from the annular body 161, the annular body 161 is used to cooperate with the bottom of the outer cover 140, and the sealing lip 162 can be tightly attached to the inner pot 110 to form a seal after contacting the inner pot 110. The annular body 161 can be designed to have an annular insertion slot, the opening of the insertion slot faces the bottom edge of the outer cover 140, and the sealing member 160 is fixed on the outer cover 140 by insertion.

[0057] As shown in Figure 3As shown, in order to make the seal 160 and the outer cover 140 fit more closely, the bottom of the outer cover 140 is provided with a second flange 141 extending outward, the second flange 141 extends radially outward, so that the opening direction of the slot on the annular body 161 is radially inward, the second flange 141 is inserted into the slot of the annular body 161, the installation of the outer cover 140 and the seal 160 is completed, and no auxiliary adhesive such as glue is needed for installation, thereby improving the safety of the entire outer cover 140. The second flange 141 extends radially outward because when the outer cover 140 is taken out or placed, the resistance of the water or food in the inner pot 110 is axial or vertical, and the second flange 141 and the annular body 161 are radially fitted, so it is not easy to be affected by these resistances and fall off. In addition, the second flange 141 thickens the thickness of the connection between the outer cover 140 and the annular body 161. Since the outer cover 140 itself only serves to isolate water vapor and does not need to be too thick, the thickened second flange 141 can better form a larger friction force between the slot opened on the annular body 161, thereby reducing the probability of the seal 160 and the outer cover 140 falling off. The sealing lip 162 can be designed to be a horn-shaped opening with a small upper part and a large lower part. When the sealing lip 162 contacts the bottom wall of the inner pot 110, it can expand the contact surface between the sealing lip 162 and the bottom wall of the inner pot 110, and better form a sealed state.

[0058] As shown in Figure 4 , Figure 5 The inner cover 130 can also be cylindrical, preferably horn-shaped with a small upper part and a large lower part, which is conducive to steam concentration. The inner cover 130 has a horizontal steam outlet 135 at the upper part to allow steam to flow out of the inner cover 130. The bottom of the inner cover 130 is provided with a first flange 131 extending outward. When the inner cover 130 is placed on the inner pot 110, the first flange 131 can leave a first liquid flow channel 113 between the inner cover 130 and the bottom wall of the inner pot 110, allowing water in the inner pot 110 to flow into the inner cover 130. When the outer cover 140 is placed on the inner cover 130, the first flange 131 can prevent the sealing lip 162 of the outer cover 140 from contacting the inner pot 110, ensuring that the first liquid flow channel 113 is unobstructed.

[0059] The first flange 131 can be designed to include a flange body 132, an upper support portion 133 on the upper surface of the flange body 132, and a lower support portion 134 on the lower surface of the flange body 132. The upper support portion 133 is used to lift the sealing lip 162 of the outer cover 140 to prevent it from contacting the bottom wall of the pot liner 110. The lower support portion 134 is used to form a first liquid flow channel 113 between the inner cover 130 and the pot liner 110. Specifically, the upper support portion 133 includes a plurality of upper bosses spaced apart along the upper surface of the flange body 132, and the lower support portion 134 includes a plurality of lower bosses spaced apart along the lower surface of the flange body 132. In addition to the boss structure, the upper support portion 133 and the lower support portion 134 can also be in the form of a plurality of spaced-apart cylinders or prisms.

[0060] like Figure 6 , Figure 7 As shown, in normal use, the inner cover 130 is placed inside the pot liner 110, typically at the center of the pot liner 110. The cover assembly and the pot liner 110 form a first cooking cavity 111, and the inside of the cover assembly forms a second cooking cavity 112. The outer cover 140 covers the inner cover 130, forming an accommodating space 114 between the outer cover 140 and the inner cover 130. The first liquid flow channel 113 is located between the inner cover 130 and the bottom wall of the pot liner 110. Because the upper support 133 lifts the sealing lip 162, and the upper protrusions of the upper support 133 are spaced apart, a second liquid flow channel 115 is formed between the upper support 133 and the sealing member 160, allowing the accommodating space 114 to communicate with the first cooking cavity 111.

[0061] When cooking, the inner pot 110 is pressurized by the air supply device 170, and the liquid in the first cooking cavity 111 is forced to flow into the second cooking cavity 112 through the first liquid flow channel 113. As the pressure increases, the water in the second cooking cavity 112 is forced to flow through the steam outlet 135 on the top of the inner cover 130, and then through the steam inlet 121 into the steaming assembly 120, thereby soaking the food in the steaming assembly 120. To ensure that the soaking water level is in place, the liquid level sensor 150 is positioned higher than the bottom of the second cooking cavity 112, so that there is enough water below the liquid level sensor 150 to press into the steaming assembly 120 and submerge the food. After soaking is complete, the air supply device 170 removes the pressure, the water levels in the first cooking cavity 111 and the second cooking cavity 112 return to the same level, and the heating device 180 begins to work, heating the water in the first cooking cavity 111. The water in the first cooking cavity 111 turns into steam, and water bubbles carrying the steam rise. These water bubbles are broken when passing through the steam outlet 135, and the water flows into the accommodation space 114 between the inner cover 130 and the outer cover 140, separating the water and the steam. The water enters the accommodation space 114 from the second liquid flow channel 115 at the bottom and flows back into the first cooking cavity 111, and the steam enters the steaming assembly 120 through the steam inlet 121 to heat the food.

[0062] If the user forgets to put the inner cover 130 into the inner pot 110, the sealing lip 162 of the sealing member 160 at the bottom of the outer cover 140 will directly contact the bottom wall of the inner pot 110 due to the loss of support from the first flange 131 of the inner cover 130. At this time, the first liquid flow channel is blocked by the sealing member at the bottom of the outer cover, and the interior of the outer cover 140 is separated from the space between the outer cover 140 and the inner pot 110 into two independent spaces. After the air pump is pressurized, the liquid level sensor 150 will not be able to sense the change in liquid level, and will immediately send an alarm signal to prompt the user, thereby ensuring that the inner cover 130 is installed before normal operation begins, and the user can cook food with good taste.

[0063] Embodiment Two

[0064] The difference between Embodiment One and Embodiment Two is that the structure of the first flange 131 of the inner cover 130 in Embodiment Two is different. The first flange 131 is in the form of a ring surrounded by waves. The wave crests are used to support the sealing member 160 of the outer cover 140, and the second liquid flow channel 115 is formed between two wave crests to connect the accommodation space 114 and the first cooking cavity 111.
