Cabinet components and cooking equipment

Abstract

This invention provides a cabinet assembly and cooking device, relating to the field of kitchen appliance technology. The cabinet assembly includes an inner liner, a heating element, and a pump body. The heating element is disposed inside the inner liner. The liquid outlet of the pump body communicates with the interior of the inner liner, allowing liquid flowing from the pump body's outlet to reach the heating element. The pump body pumps liquid into the inner liner, and the liquid flows out of the pump body to the heating element, which heats the liquid to generate steam, which can be used to cook food. Because the liquid is pumped into the inner liner through the pump body, when the pressure inside the inner liner is high, it prevents the liquid from being forced back into the pump body, thereby ensuring the normal operation of the cabinet assembly.

Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a cabinet assembly and cooking equipment. Background Technology

[0002] Most electric steamers currently on the market are ordinary atmospheric pressure electric steamers. These steamers take longer to cook food, consume more energy, and result in greater nutrient loss in the food.

[0003] If the inner liner of the electric steamer is kept under pressure during the steaming process, the steam temperature inside the liner will be higher than that at atmospheric pressure, which can shorten the steaming time and reduce energy consumption.

[0004] Existing electric steamers have a steam generator and water system installed outside the inner tank. When the air pressure inside the inner tank is too high, it will force the water in the water system back, causing the electric steamer to malfunction. Summary of the Invention

[0005] The purpose of this invention is to provide a housing assembly to solve the technical problem in the prior art where excessively high internal air pressure in the inner liner causes water pressure to be drawn back into the water system.

[0006] The housing assembly provided by the present invention includes an inner liner, a heating element, and a pump body;

[0007] The heating element is disposed inside the inner liner;

[0008] The outlet of the pump body is connected to the inside of the inner tank, and the liquid flowing out of the outlet of the pump body can flow to the heating element.

[0009] Furthermore, the housing assembly also includes an impeller;

[0010] The impeller is disposed inside the inner liner, and the liquid flowing out of the outlet of the pump body can flow to the impeller, and the impeller can throw the liquid to the heating element.

[0011] Furthermore, the heating element is arranged around the impeller.

[0012] Furthermore, the liquid flowing out of the pump body's outlet is positioned above the impeller.

[0013] Furthermore, the impeller includes a plurality of blades, which are spaced apart circumferentially along the impeller; each blade has a first end face, which is concave.

[0014] Furthermore, the enclosure assembly also includes a pressure relief channel;

[0015] The outer side of the inner liner is connected to the inner side of the inner liner through the pressure relief channel; a valve is provided in the pressure relief channel, and when the air pressure inside the inner liner is greater than the pressure relief pressure, the air pressure inside the inner liner drives the valve to open.

[0016] Furthermore, the housing assembly also includes a pressurization channel;

[0017] The outer side of the inner liner is connected to the inside of the inner liner through the pressurization channel; a valve is provided in the pressurization channel, and when the air pressure inside the inner liner is less than the preset air inlet pressure, atmospheric pressure drives the valve to open.

[0018] Furthermore, the valve component includes a valve body and a valve core;

[0019] The valve body has an internal cavity; the valve body is provided with an air inlet and an air outlet;

[0020] The valve core is disposed in the cavity, and an elastic element is provided between the valve body and the valve core. The valve core can move along the extension direction of the cavity to open or close the air inlet.

[0021] Furthermore, along the extending direction of the cavity, the two ends of the valve body are respectively the first wall surface and the second wall surface;

[0022] The air inlet is located on the first wall surface, and the exhaust outlet is located on the second wall surface; the elastic element is located between the second wall surface and the valve core.

[0023] Another objective of this invention is to provide a cooking device, including the housing assembly provided by this invention.

[0024] The present invention provides a cabinet assembly including an inner liner, a heating element, and a pump body. The heating element is disposed inside the inner liner. The liquid outlet of the pump body communicates with the interior of the inner liner, and the liquid flowing out of the pump body's outlet can flow to the heating element. The pump body pumps the liquid into the inner liner, and the liquid flows out of the pump body and then to the heating element. The heating element heats the liquid to generate steam, which can be used for cooking food. Because the liquid is pumped into the inner liner through the pump body, when the air pressure inside the inner liner is high, it can prevent the liquid from being forced back into the pump body, thereby ensuring the normal operation of the cabinet assembly.

Detailed Implementation

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a housing assembly and a cooking device. Several embodiments are given below to describe the housing assembly and cooking device provided by this invention in detail.

[0036] Example 1

[0037] The enclosure assembly provided in this embodiment, such as Figures 1 to 7 As shown, it includes an inner liner 1, a heating element 4, and a pump body 12; the heating element 4 is disposed inside the inner liner 1; the liquid outlet of the pump body 12 is connected to the inside of the inner liner 1, and the liquid flowing out of the liquid outlet of the pump body 12 can flow to the heating element 4.

[0038] Pump body 12 pumps liquid into the inner liner 1. After flowing out of pump body 12, the liquid can flow to heating element 4, which heats the liquid to generate steam, which can be used to cook food. Since the liquid is pumped into the inner liner through pump body 12, when the air pressure inside the inner liner is high, it can prevent the liquid from being forced back into pump body 12, thereby ensuring the normal operation of the cabinet assembly.

[0039] The pump body 12 can be located inside or outside the inner liner 1. Preferably, the pump body 12 is located outside the inner liner 1, and the outlet of the pump body 12 is connected to the pipe body 5, which extends into the inner liner 1, thus avoiding the pump body 12 occupying the internal space of the inner liner 1.

[0040] The liquid flowing out of the outlet of the pump body 12 can be located above or below the heating element 4, or in any suitable position, as long as the liquid flowing out of the outlet of the pump body 12 can flow to the heating element 4.

[0041] For example, when the pump body 12 is located inside the inner liner 1, the outlet of the pump body 12 is located above the heating element 4, and the liquid flowing out of the outlet of the pump body 12 can drip onto the heating element 4; or, the outlet of the pump body 12 is located below the heating element 4, and the liquid flowing out of the outlet of the pump body 12 can spray onto the heating element 4.

[0042] When the pump body 12 is located outside the inner tank 1, the pipe body 5 is located above the heating element 4, and the liquid flowing out of the pipe body 5 can drip onto the heating element 4; or, the pipe body 5 is located below the heating element 4, and the liquid flowing out of the pipe body 5 can spray onto the heating element 4.

[0043] Furthermore, the housing assembly also includes an impeller 6; the impeller 6 is located inside the inner liner 1, and the liquid flowing out of the outlet of the pump body 12 can flow to the impeller 6, and the impeller 6 can throw the liquid to the heating element 4.

[0044] Impeller 6 is installed inside the inner tank 1. Impeller 6 can rotate around the axis of impeller 6. The liquid flowing out of the outlet of pump body 12 flows to impeller 6 and is then thrown out by impeller 6 to heating element 4.

[0045] For example, when the pump body 12 is located outside the inner tank 1, the pipe body 5 is located above the impeller 6. After the liquid flows out of the pipe body 5, it drips onto the impeller 6. The liquid dripping onto the impeller 6 is thrown out by the centrifugal force of the impeller 6 to the heating element 4, and the heating element 4 heats the liquid to generate steam; or, the pipe body 5 is located below the impeller 6. After the liquid flows out of the pipe body 5, it is sprayed onto the impeller 6. The liquid sprayed onto the impeller 6 is thrown out by the centrifugal force of the impeller 6 to the heating element 4, and the heating element 4 heats the liquid to generate steam.

[0046] When the pump body 12 is installed inside the inner tank 1, the outlet of the pump body 12 is located above the impeller 6, and the liquid flows out of the outlet of the pump body 12 and drips onto the impeller 6; or, the outlet of the pump body 12 is located below the impeller 6, and the liquid flows out of the outlet of the pump body 12 and is sprayed onto the impeller 6.

[0047] The liquid is thrown out by the impeller 6 to the heating element 4, which can make the liquid more evenly distributed on the heating element 4, so that the liquid flowing on the heating element 4 can evaporate in time, preventing the liquid from flowing into the inner liner 1 without evaporation and causing the liquid to accumulate in the inner liner 1.

[0048] The heating element 4 can be arc-shaped, straight-shaped, or ring-shaped, etc.

[0049] In order for the impeller 6 to throw the liquid to the heating element 4, the heating element 4 can be set on one side of the impeller 6, such as above or below the impeller 6, or the heating element 4 can be set around the impeller 6.

[0050] Preferably, the heating element 4 is arranged around the impeller 6.

[0051] Specifically, the heating element 4 is annular and surrounds the outside of the impeller 6. When the impeller 6 throws out liquid, since the heating element 4 is arranged around the impeller 6, most of the liquid thrown out by the impeller 6 can be thrown onto the heating element 4 and then heated by the heating element 4 to form steam, reducing the amount of liquid that does not drip onto the heating element 4 and preventing the liquid from accumulating inside the inner liner 1.

[0052] The liquid flowing out of the outlet of the pump body 12 can be positioned above the impeller 6, or horizontally on one side of the impeller 6, or any other suitable position.

[0053] Preferably, the liquid flowing out of the outlet of the pump body 12 is positioned above the impeller 6.

[0054] For example, when the pump body 12 is located inside the inner liner 1, the outlet of the pump body 12 is located above the impeller 6; when the pump body 12 is located outside the inner liner 1, the outlet of the pipe body 5 is located above the impeller 6.

[0055] The liquid flowing out of the outlet of the pump body 12 drips down from above the impeller 6 to the impeller 6. The impeller 6 can catch the liquid well and throw the liquid out to the heating element 4, preventing the liquid from flowing into the inner tank 1 if it is not caught by the impeller 6, which would cause the liquid to accumulate in the inner tank 1.

[0056] Furthermore, the impeller 6 includes multiple blades, which are spaced apart circumferentially along the impeller 6; each blade has a first end face, which is concave.

[0057] The cross-sectional shape of the blade can be V-shaped, U-shaped, or I-shaped, or any other suitable shape.

[0058] The liquid pumped into the pipe body 5 by the pump body 12 is affected by water pressure. After the liquid leaves the pipe body 5, the dripping distance will move relatively. The first end face is concave, which allows the water droplets to fall into the bottom position of the concave first end face after dripping to the first end face, so that most of the liquid can be thrown out to the heating element 4 by the centrifugal force of the impeller 6.

[0059] Furthermore, the housing assembly also includes a pressure relief channel 7; the outside of the inner liner 1 is connected to the inside of the inner liner 1 through the pressure relief channel 7; a valve 2 is provided in the pressure relief channel 7, and when the air pressure inside the inner liner 1 is greater than the pressure relief pressure, the air pressure inside the inner liner 1 drives the valve 2 to open.

[0060] When the internal pressure of the inner liner 1 is too high (when the internal air pressure of the inner liner 1 is greater than the pressure relief pressure), the internal air pressure of the inner liner 1 will open the valve 2, thereby achieving internal pressure relief of the inner liner 1 and making the box assembly safer.

[0061] The valve 2 includes an air inlet 26 and an exhaust outlet 23. The air inlet 26 is positioned towards the inside of the inner liner 1, and the exhaust outlet 23 is positioned towards the outside of the inner liner 1.

[0062] Furthermore, the housing assembly also includes a pressurization channel 8; the outside of the inner liner 1 is connected to the inside of the inner liner 1 through the pressurization channel 8; a valve 2 is provided in the pressurization channel 8, and when the air pressure inside the inner liner 1 is less than the inlet air pressure, the atmospheric pressure drives the valve 2 to open.

[0063] After cooking is finished inside the inner pot 1, the air pressure decreases due to cooling inside the inner pot 1. When the air pressure inside the inner pot 1 is less than the intake pressure, the atmospheric pressure outside the shell 10 will open the valve 2, allowing the gas outside the shell 10 to enter the inner pot 1, thereby achieving air pressure balance inside and outside the inner pot 1.

[0064] Among them, valve 2 includes an air inlet 26 and an exhaust port 23. The air inlet 26 is arranged facing the outside of the inner liner 1, and the exhaust port 23 is arranged facing the inside of the inner liner 1.

[0065] Furthermore, the valve component 2 includes a valve body 21 and a valve core 24; the valve body 21 has a cavity inside; the valve body 21 is provided with an air inlet 26 and an air outlet 23; the valve core 24 is disposed in the cavity, and an elastic element 25 is provided between the valve body 21 and the valve core 24, and the valve core 24 can move along the extension direction of the cavity to open or close the air inlet 26.

[0066] The air inlet 26 and the exhaust port 23 are respectively connected to the cavity. When the valve core 24 closes the air inlet 26, the valve 2 is in the closed state. When the valve core 24 opens the air inlet 26, the valve 2 is in the open state.

[0067] The elastic element 25 can be any suitable form, such as a spring or an elastic pad.

[0068] Specifically, when valve 2 is fixed within the pressure relief channel 7, the valve body 21 of valve 2 is sealed to the pressure relief channel 7, the exhaust port 23 faces outwards from the inner liner 1, and the air inlet 26 faces inwards from the inner liner 1. When the internal air pressure of the inner liner 1 is less than the pressure relief pressure, the valve core 24, under the action of elastic force and atmospheric pressure, presses against the edge of the air inlet 26, thereby sealing the air inlet 26 and keeping the pressure relief channel 7 closed. When the internal air pressure of the inner liner 1 is greater than the pressure relief pressure, the valve core 24 is pushed by the internal air pressure of the inner liner 1 towards the exhaust port 23, thereby opening the air inlet 26 and keeping the pressure relief channel 7 open, allowing the gas inside the inner liner 1 to leak outwards from the inner liner 1, thus achieving the pressure relief function.

[0069] Among them, the pressure relief pressure is greater than the atmospheric pressure; after the valve component 2 is assembled, the elastic force is in a compressed state. At this time, the valve core 24 is pressed against the edge of the air inlet 26, and the elastic force of the elastic component 25 is the pre-elastic force of the elastic force.

[0070] The pre-elastic force of the elasticity can be set according to the specific requirements of the inner liner 1, and the pre-elastic force of the elasticity can be adjusted according to the usage requirements to adjust the pressure relief of the valve 2.

[0071] The enclosure assembly also includes a shell 10; the shell 10 is fitted over the outer side of the inner liner 1; the exterior of the shell 10 is connected to the interior of the inner liner 1 via a pressure relief channel 7. The exterior of the shell 10 and the interior of the inner liner 1 can be directly connected via the pressure relief channel 7, or a heat dissipation duct 9 can be provided on the exterior of the inner liner 1, with the pressure relief channel 7 connecting the heat dissipation duct 9 and the interior of the inner liner 1, and the heat dissipation duct 9 also connecting to the exterior of the shell 10.

[0072] Preferably, the maximum pressure of the pump body 12 is A, and the pressure relief pressure of the valve 2 is B, where A > B.

[0073] The maximum pressure that the pump body 12 can withstand is A. When A is greater than B, when the air pressure inside the inner liner 1 reaches the pressure relief pressure, the pump body 12 can provide a pressure greater than the pressure relief pressure to prevent the liquid from being forced back into the pump body 12.

[0074] Specifically, when the valve body 21 is fixed inside the pressurization channel 8, the valve body 21 is sealed to the pressurization channel 8, the air inlet 26 faces outwards from the inner liner 1, and the exhaust port 23 faces inwards from the inner liner 1. When the internal air pressure of the inner liner 1 is greater than the inlet pressure, the valve body 21 is pushed by the internal air pressure of the inner liner 1 and presses against the edge of the air inlet 26, thereby sealing the air inlet 26 and keeping the pressurization channel 8 closed. When the internal air pressure of the inner liner 1 is less than the inlet pressure, the air outside the housing 10 pushes the valve body 21 toward the exhaust port 23, thereby opening the air inlet 26 and keeping the pressurization channel 8 open. Air outside the housing 10 enters the inner liner 1, achieving pressure balance. After the pressure inside and outside the inner liner 1 is balanced, the valve body 21 closes the air inlet 26 again.

[0075] The intake pressure can be the same as or less than atmospheric pressure. The intake pressure can be set according to the specific requirements of the inner liner 1, and the pre-elastic force of the elastic element 25 can be adjusted according to the usage requirements to regulate the intake pressure of the valve 2.

[0076] After the valve component 2 is assembled, the valve core 24 abuts against the edge of the air inlet 26, and the elastic force of the elastic component 25 is the pre-elastic force of the elastic component 25.

[0077] The pre-elastic force of the elastic element 25 can be set according to the specific requirements of the inner liner 1 to adjust the air intake pressure of the valve 2.

[0078] The enclosure assembly also includes a shell 10; the shell 10 is fitted onto the outside of the inner liner 1; the outside of the shell 10 and the inside of the inner liner 1 are connected through a pressurization channel 8. The outside of the shell 10 and the inside of the inner liner 1 can be directly connected through the pressurization channel 8, or a heat dissipation duct 9 can be provided on the outside of the inner liner 1, with the pressurization channel 8 connecting the heat dissipation duct 9 to the inside of the inner liner 1, and the heat dissipation duct 9 also connecting to the outside of the shell 10.

[0079] The air inlet 26 and the exhaust outlet 23 can be set relative to each other or not relative to each other.

[0080] In this embodiment, along the extension direction of the cavity, the two ends of the valve body 21 are a first wall surface and a second wall surface 22, respectively; the air inlet 26 is disposed on the first wall surface, and the exhaust port 23 is disposed on the second wall surface 22; the elastic element 25 is disposed between the second wall surface 22 and the valve core 24.

[0081] When the valve body 21 is installed in the pressure relief channel 7, the first wall surface is located at the bottom end of the valve body 21, and the second wall surface 22 is located at the top end of the valve body 21. The first wall surface faces the inside of the inner liner 1, and the second wall surface 22 faces the outside of the inner liner 1.

[0082] When the valve body 21 is installed in the pressurization channel 8, the first wall surface is located at the top of the valve body 21, and the second wall surface 22 is located at the bottom of the valve body 21. The first wall surface faces the outside of the inner liner 1, and the second wall surface 22 faces the inside of the inner liner 1.

[0083] Furthermore, the housing assembly also includes a controller, which is connected to the pump body 12 and can control the pump body 12 to start and stop cyclically at preset intervals.

[0084] The preset time can be any suitable time such as 1s, 2s, 3s, 4s, or 5s. For example, the controller controls the pump body 12 to run for 3s, then controls the pump body 12 to stop for 3s, then controls the pump body 12 to run for 3s, and so on, continuously cycling. In this way, when the pump body 12 is running, after the liquid drips onto the heating element 4, the pump body 12 stops running for the preset time. During this time, the liquid can be fully evaporated, preventing the liquid that has not evaporated in time from dripping into the inner tank 1 and forming condensate.

[0085] The liquid source for the pump body 12 can be a water tank 13 or a household water system (such as a tap water pipe or a water purifier). The water inflow of the pump body 12 can be controlled by a flow meter or by the start and stop time of the pump body 12.

[0086] In addition, the cabinet assembly also includes a steam oven door 101 and a door lock structure 3. The inner liner 1 has a loading and unloading port. The steam oven door 101 is connected to the housing 10 via a hinge assembly. The steam oven door 101 can open or close the loading and unloading port. When the loading and unloading port is closed, the door lock structure 3 can lock the steam oven door 101 and the inner liner 1 to prevent steam from escaping from the loading and unloading port.

[0087] The door lock structure 3 includes a latch 31 and a lock hole 32. The latch 31 is set on the steam oven door 101 and is positioned opposite to the hinge assembly. The lock hole 32 is set on the housing 10. The latch 31 and the lock hole 32 cooperate to lock the steam oven door 101 and the inner liner 1, thus sealing the opening. The door lock structure 3 can be mechanical or electronic.

[0088] A cover plate 11 is provided on the outside of the impeller 6 and the tube body 5. The cover plate 11 is connected to the inner surface of the inner liner 1. The cover plate 11 can prevent the user from putting their hands into the impeller 6 or the tube body 5, thus preventing injury to the user.

[0089] Example 2

[0090] The cooking device provided in this embodiment includes the housing assembly provided in Embodiment 1. The pump body 12 pumps liquid into the inner pot 1. After flowing out of the pump body 12, the liquid can flow to the heating element 4, which heats the liquid to generate steam. The steam can be used to cook food. Because the liquid is pumped into the inner pot through the pump body 12, when the air pressure inside the inner pot is high, it can prevent the liquid from being forced back into the pump body 12, thereby ensuring the normal operation of the housing assembly.

[0091] The cooking equipment can be a steam oven or any suitable equipment such as a steam oven or a combination steam oven.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
