The refrigeration module 200 has a module housing 210, with a refrigeration assembly 220 (see fig. 3 and 18) disposed within the module housing 210. Of course, in other embodiments, the cooking chamber 120, the heating assembly 140 and the cooling assembly 220 may be disposed in the same housing, i.e., forming a unitary structure, rather than being disposed in two separate housings. In the embodiment, the cooling module 220 is designed as an integral module, and the refrigeration module 200 and the device body 100 can be separately and independently assembled and then jointly assembled, so that the assembly efficiency is higher, and the maintenance and the replacement can be more conveniently carried out by separating.

The cooking chamber 120 has a cooking cavity 122 for receiving food, and the food received in the cooking cavity 122 is cooked by the heating action of the heating assembly 140. Wherein, different tastes and nutrition can be obtained according to different heating modes. Specifically, referring to fig. 1, 2 and 18, the cooking chamber 120 has a chamber wall 121, and the chamber wall 121 has a food material taking and placing opening 123, so that a user can take and place food materials conveniently. In the present application, the side of the food material taking and placing opening 123 is referred to as the front of the device, and the side of the food material taking and placing opening 123 faces the user in normal use, but in some embodiments, the side of the food material taking and placing opening 123 may face other directions in use. The door 130 is movably provided to open and close the food material taking and placing opening 123. When the door 130 is closed, a closed cavity can be formed with the cooking chamber 120, which facilitates the processing of food materials.

Referring to fig. 18, the wall 121 of the cooking chamber 120 may further include a back side wall 124, a left side wall 125, a right side wall 126, a bottom wall 127 and a top wall 128, the back side wall 124 is disposed opposite to the food material taking and placing opening 123, the left side wall 125 and the right side wall 126 are disposed between the food material taking and placing opening 123 and the back side wall 124, the top wall 128 is disposed at the top of the cooking chamber 120, and the bottom wall 127 is disposed at the bottom of the cooking chamber 120. The left side wall 125 and the right side wall 126 refer to that when the food material taking and placing opening 123 faces the user, the side wall located on the left hand of the user is the left side wall 125, and the side wall located on the right hand of the user is the right side wall 126. Of course, each silo wall 121 may also be named differently as the relative position of the equipment and the user changes. In fig. 18, the cooking chamber 120 has a square configuration, but in other embodiments, the cooking chamber 120 may have other shapes, such as a spherical or elliptical configuration.

The heating assembly 140 is used to heat food material placed in the cooking chamber 122. The heating assembly 140 may employ, but is not limited to, at least one of a microwave assembly, a steam heating assembly, an electric grill heating assembly, and other food cooking heating assemblies. For example, referring to fig. 3, in the embodiment shown in fig. 3, the heating assembly 140 includes a steam heating assembly 142 and an electric oven heating assembly 141, so that the food cooking apparatus 1 has both functions of an oven and steam heating. Referring to fig. 3, in some embodiments, the steam heating assembly 142 is disposed on the back side wall 124 or other compartment walls 121 of the cooking compartment 120, and the other compartment walls 121 may be the top wall 128, the bottom wall 127 or the left side wall 125, the right side wall 126, etc. of the cooking compartment 120. The electric grill heating element 141 may be disposed on at least one wall 121 of the cooking chamber 120, for example, the back side wall 124, the top wall 128, or other positions.

In order to be able to keep food fresh, the food cooking apparatus 1 is provided with a refrigeration assembly 220. The refrigeration assembly 220 has a refrigeration compartment 221, a refrigeration member 222 and a first fluid drive 223. The refrigeration compartment 221 has a refrigeration cavity 2211, and the refrigeration assembly 220 can form cold air in the refrigeration cavity 2211. When keeping fresh, this air conditioning can access to culinary art chamber 122, reduces the temperature in the culinary art chamber 122 to the realization is kept fresh to eating the material, and the user can place eating the material in the culinary art chamber 122 in advance, and the reservation time heats the culinary art.

The refrigeration compartment 221 further has a first air inlet 2322 and a first air outlet 2321, which are communicated with the refrigeration cavity 2211, and in this embodiment, the first air inlet 2322 and the first air outlet 2321 are collectively referred to as a first air vent 232. The two ends of the first vent 232 are respectively communicated with the refrigeration cavity 2211 and the cooking cavity 122 directly or indirectly, and the on-off state of the refrigeration cavity 2211 and the cooking cavity 122 can be controlled by controlling the on-off state of the first vent 232.

Referring to fig. 6 and 18, in some embodiments, the first air inlet 2322 and the first air outlet 2321 are disposed on the refrigeration compartment 221 in a penetrating manner, so that the refrigeration assembly 220 can input cold air into the cooking cavity 122 through at least the first air outlet 2321 to reduce the temperature in the cooking cavity 122. That is, at least one first air outlet 2321 delivers cool air from the cooling chamber 2211 to the cooking chamber 122. A cold air input channel which is communicated from the cooling cavity 2211 to the cooking cavity 122 in one way can be formed between the cooling cavity 2211 and the cooking cavity 122, and the air in the cooking cavity 122 can be discharged out of the cooking cavity 122 through other openings. Referring to fig. 6 and 18, in some embodiments, the first air outlet 2321 and the first air inlet 2322 are respectively communicated with the refrigeration cavity 2211 and the cooking cavity 122 to form a circulation air duct, and this structure of circularly communicating the refrigeration cavity 2211 with the cooking cavity 122 is beneficial to preventing cold air from leaking out, so as to improve the cooling efficiency of the refrigeration assembly 220 on the cooking cavity 122, and enable the refrigeration assembly to reach a desired low-temperature state more quickly or reach a lower temperature.

The first fluid driver 223 is used to drive the air to flow toward the first outlet 2321. Preferably, the first fluid driver 223 drives the airflow from the first air inlet 2322 to the first air outlet 2321. The cooling member 222 has a cooling portion 222, and the cooling portion 222 is at least partially disposed in the cooling cavity 2211 for cooling the air flow passing through. Referring to fig. 6, in some embodiments, the first fluid driver 223 is disposed in a region between the first air inlet 2322 and the first air outlet 2321, so as to drive the air to flow toward the first air outlet 2321 more easily. Of course, in other embodiments, the first fluid driver 223 may be disposed at other locations. The first air outlet 2321 is communicated with the cooking cavity, and is used for inputting cooled air flow into the cooking cavity.

Further, referring to fig. 6-10, in some embodiments, the cooling compartment 221 has a base 2214 and a cover 231, and the base 2214 and the cover 231 are fixed and form a cooling cavity 2211, which includes the cooling cavity 2211 directly formed by the base 2214 and the cover 231, and also includes the cooling cavity 2211 formed by the base 2214 and the cover 231 together with other components. Both the base 2214 and the cover 231 may be integrally formed, or may be assembled by joining a plurality of sub-components.

Specifically, as an example, referring to fig. 6-10, in some embodiments, the cover 231 has a convex shell 2314 protruding toward the base 2214, the base 2214 has a matching portion 2215 matching with the convex shell 2314, and in the illustrated embodiments, the matching portion 2215 can be in the form of a groove or a protrusion, so that the convex shell 2314 can be embedded or abutted onto the matching portion 2215 to form a positioning. The base 2214 and the cover 231 may be fastened, welded, adhered, snapped, etc. by screws.

Of course, in addition to the above structure, the refrigeration compartment 221 may also adopt other structures capable of forming one closed refrigeration cavity 2211, and the refrigeration compartment 221 is not limited to the illustrated flat compartment structure, and may also be a square, spherical, channel-shaped or other structures to form refrigeration cavities 2211 of different shapes.

Generally, the air flow output from the air outlet end of the first fluid driver 223 is not uniformly distributed, and even some air flows output from the air outlet end of the first fluid driver 223 are liable to form a vortex shape, which results in that the air flow cannot be better and more uniformly applied to the cooling portion 222, and cannot be more effectively heat-transferred with the cooling portion 222, which greatly reduces the cooling efficiency of the cooling assembly.

In view of the above, referring to fig. 8, in some embodiments, at least one flow guiding element 246 is disposed in a region between the air outlet end of the first fluid driving element 223 and the cooling portion 222, the flow guiding element 246 is used to form at least two flow guiding air channels 247 extending from the air outlet end of the first fluid driving element 223 to the cooling portion 222, and the flow guiding air channels 247 guide the air flow to the cooling portion 222. By the combing of the guide air ducts 247, the air flow is guided more uniformly to each area of the cooling portion 222, so that the cooling portion 222 can contact more air flow to a greater extent to reduce the temperature of the air flow.

The flow guide 246 is a structure that is protrudingly provided in the refrigerating chamber 2211. Of course, the baffle 246 may take various shapes and configurations, and its purpose is to form a baffle duct 247 that can direct airflow to different locations of the cooling portion 222.

Further, referring to fig. 6-10, in some embodiments, a partition 2216 is included, the partition 2216 is disposed between the base 2214 and the cover 231, and the partition 2216 and the base 2214 form a first refrigeration cavity 2212. At least a portion of the cooling portion 2221 of the cooling member 222 is disposed in the first cooling chamber 2212. The first refrigeration cavity 2212 may be in communication with the first air outlet 2321 to direct the chilled air exiting the first air outlet 2321. The first refrigeration cavity 2212 may also be in communication with the first gas inlet 2322 so that gas from the outside or the cooking cavity 122 can enter the first refrigeration cavity 2212.

The flow guide 246 is disposed within the first refrigeration cavity 2211, and may be disposed on the shelf 2216 and/or the base 2214. Referring to fig. 10, in some embodiments, the diversion member 246 is disposed on a side of the division plate 2216 facing the base 2214, and when the division plate 2216 is assembled with the base 2214, a diversion air duct 247 is formed. By providing the number of the deflectors 246, a different number and extension shape of the air guide passages 247 may be formed in the cooling chamber 2211. Referring to fig. 11, in some embodiments, the flow-guiding members 246 may be more, extending outward from the circumferential side of the first fluid driver 223. The extended shape may be a smooth arc or a dogleg shape. The smooth arc shape facilitates the formation of the guiding air duct 247 with smooth wall, which facilitates the flow of the air flow. Referring to fig. 8 and 11, in some embodiments, at least one air guide channel 247 extends from the peripheral side of the first fluid driver 223 along an arc toward the cooling portion 222.

Further, referring to fig. 7, 8 and 13-17, the cooling portion 2221 of the cooling element 222 is at least partially located in the first cooling cavity 2212, the cooling portion 2221 may include a cold end 2229 of the cooling element 222, and when a temperature conducting structure is disposed on the cold end 2229, the cooling portion 2221 further includes the temperature conducting structure. For example, referring to fig. 7, 8 and 13-17, in some embodiments, the cooling member 222 is a semiconductor cooling plate having a cold end 2229 and a hot end 22210, the cooling portion 2221 includes a cold end 2229 and temperature guiding fins 2222 connected to the cold end 2229, and the temperature guiding fins 2222 are at least partially located in the first cooling cavity 2212. The cooling part 2221 generates low temperature to be transferred to the air in the first refrigeration chamber 2212 through the heat transfer fins 2222 to form cold air.

Referring to fig. 8 and 13, in some embodiments, the cooling portion 222 has a plurality of temperature guide fins 2222, and an air flow gap 2223 extending from one side of the air guide duct 247 to one side of the first air outlet 2321 is formed between adjacent temperature guide fins 2222. The guide air duct 247 of one guide air duct 247 is communicated with the at least one air flow gap 2223, so that the one guide air duct 247 can guide the air flow into the at least one air flow gap 2223, the air flow can more smoothly pass through the air flow gap 2223, and the situation that part of the air flow cannot enter the air flow gap 2223 due to deviation of the flow direction is avoided, so that more air flow can be thermally conducted with the temperature guide fins 2222.

Further, with continued reference to fig. 8 and 13, in some embodiments, in order to enable airflow to enter the airflow gaps 2223 more smoothly, the radial end surfaces a1 of the guiding air ducts 247 are perpendicular to the extending direction a2 of the corresponding airflow gaps 2223 or form an acute angle structure. This structure can reduce the collision between the air flow flowing out from the guiding air duct 247 and the wall of the air flow gap 2223, which is too much to facilitate the air flow flowing along the air flow gap 2223 to the first air outlet 2321.

Further, since the temperature of the heat guiding fins 2222 is low during operation, the surface thereof is prone to condensation, which causes air to be condensed into liquid and hung on the surface of the heat guiding fins 2222, which will affect the heat conduction effect and the cooling effect of the heat guiding fins 2222, for this reason, referring to fig. 8 and 13, in some embodiments, the heat guiding fins 2222 of the cooling portion 222 are transversely extended, one end of the heat guiding fins 2222 close to the guiding air duct 247 is a first end 2224, and the end of the heat guiding fins 2222 away from the first end 2224 is a second end 2225, and the heat guiding fins 2222 are extended from the first end 2224 to the second end 2225 thereof in a downward inclined manner, so as to guide the liquid on the heat guiding fins 2222 to flow and drop toward the second end 2225. Wherein the definition of the lateral direction is mainly used to distinguish the vertical direction. Which can be considered to extend generally horizontally and at an oblique angle to the horizontal. This along the heat conduction fin 2222 of horizontal downward sloping, can lead the liquid on heat conduction fin 2222 surface to second end 2225 to drop from second end 2225, and then reduce because of the frosting phenomenon that the condensed liquid piles up and causes at heat conduction fin 2222, avoid heat conduction fin 2222 to influence refrigeration efficiency because of the surface frosting.

Meanwhile, positioning the first end 2224 of the temperature guiding fin 2222 closer to one end of the guiding air duct 247 can push the liquid to flow to the second end 2225 of the temperature guiding fin 2222 by the airflow generated by the first fluid driving member 223, which is more beneficial to the dropping of the liquid.

In order to promote the liquid loading flowing from the first end 2224 to the second end 2225 of the temperature guide fin 2222, in some embodiments, the temperature guide fin 2222 is located in the gas flowing region between the first air inlet 2322 and the first air outlet 2321, and in the first end 2224 and the second end 2225 of the temperature guide fin 2222, the first end 2224 of the temperature guide fin 2222 is closer to the first air inlet 2322, and the second end 2225 is closer to the first air outlet 2321, so as to promote the liquid flowing from the first end 2224 to the second end 2225 of the temperature guide fin 2222 through the gas flow.

Further, in order to prevent the liquid on the upper heat guiding fins 2222 from dripping from the second ends 2225 onto the lower heat guiding fins 2222, please refer to fig. 13 and 14, in the same or multiple cooling portions 222, the heat guiding fins 2222 are arranged in the vertical direction, and the second end 2225 of at least one heat guiding fin 2222 is protruded relative to the second end 2225 of the lower heat guiding fin 2222, so as to prevent the liquid from dripping onto the lower heat guiding fins 2222.

Alternatively, in other embodiments, the second ends 2225 of the plurality of temperature conduction fins 2222 are offset from top to bottom in the vertical direction toward the first ends 2224 thereof, and the distance of the protrusion of each temperature conduction fin 2222 relative to the adjacent temperature conduction fin 2222 therebelow may be consistent in the offset arrangement, and may change regularly as shown in fig. 13, so that the second ends 2225 of the temperature conduction fins 2222 positioned above in the plurality of temperature conduction fins 2222 are arranged in a protruding manner relative to the second ends 2225 of the temperature conduction fins 2222 therebelow. Of course, in other embodiments, the distance of the protrusion of each temperature guide fin 2222 relative to the temperature guide fin 2222 below may be different.

Referring to fig. 14, when there are a plurality of cooling portions 222 (two or more), the cooling portions 222 may be arranged in a vertical direction. In order to prevent the liquid from dropping onto the lower heat guide fins 2222, the groups of heat guide fins 2222 are arranged in the vertical direction, and at least the second ends 2225 of the lowermost heat guide fins 2222 in the upper group of heat guide fins 2222 are arranged to protrude from the second ends 2225 of the lower groups of heat guide fins 2222.

In some embodiments, there are at least two cooling portions 222, and the cooling portions 222 are arranged vertically up and down, wherein between two adjacent cooling portions 222, an orthographic projection of the second end 2225 of the upper cooling portion 222 on the horizontal plane exceeds an orthographic projection of the second end 2225 of the lower cooling portion 222 on the horizontal plane, so as to ensure that the second end 2225 of at least one temperature guide fin 2222 in the upper cooling portion 222 is convex with respect to all temperature guide fins 2222 in the lower cooling portion 222.

Further, referring to fig. 16, in some embodiments, the cooling portion 222 has a heat conducting base 2226, and the heat conducting fins 2222 are protruded from the heat conducting base 2226. The thermal conductive base 2226 and the thermal conductive fins 2222 may be formed integrally, or may be assembled together by different parts. The heat transfer fins 2222 may be contacted and fixed with the cold end 2229 of the cooling member 222 through the heat transfer base 2226 to form the cooling part 222.

In order to better guide the liquid collection, referring to fig. 16, in some embodiments, the temperature guiding fins 2222 are disposed obliquely with respect to the temperature guiding base 2226, and one end (inner side) of the temperature guiding fins 2222 close to the temperature guiding base 2226 is lower than one end (outer side) of the temperature guiding fins 2222 away from the temperature guiding base 2226. In the embodiment shown in fig. 16, the first ends 2224 of the temperature guiding fins 2222 are inclined toward the second ends 2225, while the outer sides and the inner sides of the temperature guiding fins 2222 are inclined, and the inclination of the two directions are overlapped, so that the liquid is finally guided to be collected along the corner between the temperature guiding fins 2222 and the temperature guiding base 2226 to the second ends 2225 of the temperature guiding fins 2222, and when the liquid is collected more, the liquid is more easily dropped from the second ends 2225 under the influence of gravity.

Further, referring to fig. 17, in some embodiments, the second end 2225 of the heat conducting fin 2222 has a protrusion 2227 for guiding the liquid to flow to the protrusion 2227 and fall from the protrusion 2227. The projection 2227 has a smaller area relative to the entire upper surface of the temperature conduction fin 2222, and contributes to reducing the adhesion (adhesion due to liquid surface tension) with the liquid, so that the liquid can more easily fall from the second end 2225.

Referring to fig. 17, in some embodiments, the protrusion 2227 has a pointed end to minimize the contact area between the liquid and the protrusion 2227. Of course, in a cavity embodiment, the projection 2227 may also have a smooth or other shaped end.

Further, referring to fig. 17, in some embodiments, an end of the temperature guiding fin 2222 close to the temperature guiding base 2226 is provided with a notch 2228, and the protrusion 2227 is located outside the notch 2228 (i.e., a side of the notch 2228 facing away from the first end). The notches 2228 further reduce the adhesion of the liquid to the surface of the heat transfer fins 2222 and further facilitate the liquid to fall off the second end 2225.

Further, referring to fig. 6-10, in some embodiments, a first fluid driving member 223 may be further disposed in the first refrigeration cavity 2212, and the first fluid driving member 223 is configured to drive the gas to flow through the cooling portion 2221 and towards the first gas outlet 2321, so as to increase the discharge amount of the cold gas and increase the refrigeration efficiency. In the illustrated embodiment, the first fluid driver 223 is a centrifugal fan, although other forms of fluid drivers (axial fans) may be substituted in other embodiments. The centrifugal fan is used for radially discharging air, namely the air outlet end of the centrifugal fan is the peripheral side of the centrifugal fan. The centrifugal fan may be disposed along the axial direction of the first air inlet 2322, and is arranged side by side with the cooling portion 2221, so as to reduce the space requirement of the whole first refrigeration cavity 2212 in the axial direction of the first air inlet 2322 and the outlet air, which is beneficial to reducing the size in this direction.

After the centrifugal fan or other first fluid driving members 223 discharging air radially are adopted, the refrigeration part is arranged on the peripheral side of the first fluid driving members 223, so that a flatter structure can be realized. Referring to fig. 5, in some embodiments, the axial direction of the first air outlet 2321 is a first direction, the food cooking apparatus further has a second direction and a third direction, the second direction and the third direction are perpendicular to each other and perpendicular to the first direction, and the size of the cooling bin in the second direction and/or the third direction is larger than that in the first direction, which is beneficial to reducing the size of the apparatus in the first direction.

Further, referring to fig. 6-10, in some embodiments, there is at least one cooling portion 222, the first fluid driving member 223 (e.g., a centrifugal fan) discharges air along a radial direction thereof, the cooling portion 222 is disposed on a peripheral side of the first fluid driving member 223, and the guiding air duct 247 leads to the corresponding cooling portion 222 from the peripheral side of the first fluid driving member 223. This design makes full use of the space around the first fluid driver 223, thereby reducing the size of the cooling chamber in the axial direction of the first fluid driver 223, facilitating the design of the refrigeration compartment 221 as a flattened structure, and allowing the overall apparatus to be smaller in size in the axial direction of the first fluid driver 223 when the refrigeration assembly is assembled to the apparatus main body 100.

Further, referring to fig. 8 and 9, in some embodiments, in order to more fully utilize the peripheral space of the first fluid driving member 223, there are at least two cooling portions 222, the air flow gaps 2223 between the cooling portions 222 are substantially parallel, the first fluid driving member 223 is located on one side of the area where the whole cooling portion 222 is located and vertically corresponds to the middle position of the area where the whole cooling portion 222 is located, and the guiding air ducts 247 are relatively distributed on two sides of the first fluid driving member 223 to guide the air flow to different cooling portions 222, so as to more widely utilize the air flow output by the first fluid driving member 223 and guide the air flow to all positions of the cooling portion 222.

Of course, in other embodiments, there may be one cooling portion 222 (for example, in fig. 8, two cooling portions 222 are communicated to form one cooling portion 222), the first fluid driving member 223 is located on one side of the cooling portion 222 and corresponds to the middle position of the cooling portion 222, and the guiding air ducts 247 are distributed on two sides of the first fluid driving member 223 oppositely to guide the air flow to different areas of the cooling portion 222.

Further, the cooling element 222 (for example, the cooling element 222 is a semiconductor cooling plate) further has a hot end 22210, and if the heat of the hot end 22210 can be dissipated timely and effectively, the cooling efficiency of the cooling element 222 can be further improved. In some embodiments, referring to fig. 4, 7 and 17, the refrigeration assembly further includes a side cover 251 and a heat dissipation member 253, the side cover 251 is connected to a surface of the refrigeration compartment 221 away from the cooking compartment 120 and encloses a receiving cavity, and the refrigeration sheet 222 is at least partially disposed in the receiving cavity. The hot end 22210 of the cooling plate contacts the heat sink 253 to dissipate heat, and the heat sink 253 is located on a side of the side cover 251 facing away from the accommodating cavity.

The heat dissipating member 253 may adopt various structures capable of dissipating heat, and in some embodiments, referring to fig. 4, 7 and 17, the heat dissipating member 253 is a heat dissipating fin, and the structure of the heat dissipating fin may be the same as or similar to the structure of the temperature guiding fin 2222, or may be different. Of course, in other embodiments, the heat dissipation member 253 may also adopt other disclosed heat dissipation structures.

In order to accelerate heat dissipation from hot end 22210, in some embodiments, referring to fig. 4, 7 and 17, cooling assembly 220 further includes a heat dissipation fan housing 252 and a second fluid driving member 254 (e.g., an axial fan, a centrifugal fan, etc.), in which heat dissipation fan housing 252 covers side cover 251 and forms a heat dissipation channel with side cover 251, the heat dissipation channel has a heat dissipation outlet 255, heat dissipation member 253 is located in the heat dissipation channel, and second fluid driving member 254 is used for driving air flow in the heat dissipation channel to flow through heat dissipation member 253 towards heat dissipation outlet 255.

Further, in order to protect the cooling module 220 and prevent the structure of the cooling module 220 from being damaged by the hot air flow entering the cooling module 220 during the heating and cooking process, an isolation valve assembly 230 is further included in some embodiments of the present application. The isolation valve assembly 230 has a docking station and an insulating spool 233. The docking seat may be a part of the cooling compartment 221 or the cooking compartment 120, and as can be seen in the embodiment shown in fig. 19 and 20, the lid 231 of the cooling compartment 221 directly serves as the docking seat. Alternatively, the docking cradle is fixedly disposed relative to the cooling compartment 221 and/or the cooking compartment 120, such as the docking cradle is directly or indirectly mounted on the cooling compartment 221 or the cooking compartment 120 to achieve relative fixation therebetween. The heat insulation valve core 233 is made of a high temperature resistant material or structure, and not only has a partition sealing effect, but also has a heat insulation effect. For example, the thermal insulation core 233 may be made of a metal material, or may be filled with a thermal insulation material (e.g., a conventional thermal insulation cotton) to enhance the thermal insulation effect.

The thermal insulation valve core 233 is movable relative to the first vent 232, and has a closed position and an open position on a movement locus of the thermal insulation valve core 233. Referring to fig. 19 and 20, when the thermal valve core 233 is in the closed position, the thermal valve core 233 closes the first vent 232 to isolate the cooking chamber 122 from the refrigeration chamber 2211; referring to fig. 6, when the thermal insulation valve core 233 is in the open position, the thermal insulation valve core 233 opens the first vent 232 to communicate the cooking chamber 122 with the refrigeration chamber 2211.

The movement of the thermal insulation valve core 233 relative to the first air vent 232 may be lateral, axial, or reversed, etc., referring to fig. 6, 19 and 20, in some embodiments, when the thermal insulation valve core 233 moves laterally along the first air vent 232, the first air vent 232 is cut off. Of course, the control of the heat insulation valve core 233 to block the first vent hole 232 may be realized by directly blocking the first vent hole 232 by the heat insulation valve core 233, or may be realized by cutting off another channel communicating with the first vent hole 232 by the heat insulation valve core 233, that is, the heat insulation valve core 233 may, but need not, be in direct contact with the first vent hole 232.

The thermal insulation valve core 233 moves transversely relative to the first air port 232, so that the thermal insulation valve core 233 occupies a smaller space in the axial direction of the first air port 232 as a movement space thereof, and the transverse space on the peripheral side of the first air port 232 can be fully utilized, which is beneficial to reducing the volume of the equipment in the axial direction of the first air port 232.

The movement track of the thermal insulation valve core 233 refers to a track formed by any point of the movement part on the thermal insulation valve core 233 in the movement process of opening and closing the first vent 232. In some embodiments, a component of the motion trajectory of the thermal insulation valve core 233 in the radial direction of the first air vent 232 is greater than zero, that is, the direction of the motion trajectory of the thermal insulation valve core 233 can be divided into two components, namely, a motion trajectory extending along the axial direction of the first air vent 232 (i.e., perpendicular to the radial plane of the first air vent 232, and coinciding with or parallel to the axial direction of the first air vent 232) and a motion trajectory extending along the radial direction of the first air vent 232, and the component of the motion trajectory of the thermal insulation valve core 233 extending along the radial direction of the first air vent 232 is greater than 0.

Further, the movement of the thermal insulation valve core 233 relative to the first air vent 232 can be freely selected under the condition that the lateral movement relative to the first air vent 232 can be realized, and the first air vent 232 can be cut off and opened, for example, in some embodiments, the thermal insulation valve core 233 can be translated or rotated along the outer surface of the cover 231. The translation means that the movement track of the heat insulation valve core 233 is substantially located in a plane (not limited to a horizontal plane and a vertical plane), as shown in fig. 19 to 20, and the heat insulation valve core 233 is translated back and forth in the left and right directions in the figure. Of course, the translation means that the main motion track of the thermal insulation spool 233 is substantially in a plane, and due to manufacturing errors, assembly errors and changes in specific matching structures, the thermal insulation spool 233 may also have some floating motion perpendicular to its translation plane during the translation process, and these situations are also considered as a form of translation in the present embodiment. The translation trajectory of the thermal insulation spool 233 may be one or a combination of two or more of a straight line, a curved line, a broken line, a ring (i.e., a closed path, which may be a circular ring, an elliptical ring, or an annular polygon, etc.), and a special shape. The rotation means that the heat insulation valve core 233 rotates in a circular shape, for example, rotates around a point thereof.

Of course, this translation and rotation are only examples of the movement of the thermal isolation spool 233, and in other embodiments, other movement may be selected.

Further, to control the movement of the isolation valve spool 233, the isolation valve assembly 230 has a driver 234, the driver 234 being connected to the isolation valve spool 233 for driving the isolation valve spool 233 between the closed and open positions. The driving member 234 may be an electrically controlled driving member, i.e. a user inputs an electrical signal command or an equipment system automatically outputs a control signal to control the operating state of the electrically controlled driving member, for example, the electrically controlled driving member may be an existing electrically controlled driving member such as a rotating motor, a linear motor, an air cylinder, a hydraulic cylinder, an electromagnet driving member, etc. And/or, the driving member 234 may be a manual driving member, i.e., a force signal is manually input by a user through a mechanical transmission structure, for example, the manual driving member may be a mechanical control structure adopted by a handle, a push-pull rod, a rotating disc, etc., so as to drive the movement of the thermal insulation valve core 233.

Referring to fig. 19 and 20, in some embodiments, the driving member 234 is driven by a motor to improve the convenience of controlling the valve core. The driving member 234 may be directly connected to the thermal insulation spool 233 to achieve the interlocking. Of course, the isolation valve assembly 230 also has a transmission mechanism, the output end of the driving member 234 is connected to the transmission mechanism for driving the transmission mechanism to move, and the transmission mechanism is movably connected to the thermal insulation valve core 233 for driving the thermal insulation valve core 233 to move.

Referring to fig. 19-20, in some embodiments, the driving member 234 is a motor, and may be a rotating motor. The transmission mechanism is a screw-nut transmission pair, the motor is connected with a screw 2381 of the screw-nut transmission pair, the motor outputs rotary motion to drive the screw 2381 to rotate, further the transmission nut 2382 axially reciprocates along the screw 2381, the nut 2382 of the screw-nut transmission pair is connected with the heat insulation valve core 233 to drive the heat insulation valve core 233 to axially reciprocate along the screw 2381, and switching of the heat insulation valve core 233 between an opening position and a closing position is achieved. The transmission mode is simple and stable, which is beneficial to the simplification of the whole structure volume and is also convenient for realizing the control of the first air inlet 2322 and the first air outlet 2321 by the heat insulation valve core 233.

The transmission mechanisms shown in the above embodiments may be replaced with various known transmission mechanisms such as a rack and pinion transmission pair, a synchronous belt transmission pair, or a worm and gear transmission pair.

Further, since the cooking chamber 120 is in a high temperature environment when cooking food, the temperature is generally transmitted from the cooking chamber 120 to the surroundings, and also to the heat insulation valve core 233 and the driving member 234 to some extent. When the actuator 234 is a manual actuator, heat may be transferred to the user's grip, which, if too hot, may interfere with the user's handling experience. When the driving member 234 is an electrically controlled driving member, too high an ambient temperature is not favorable to the working efficiency of the electrically controlled driving member, and may reduce the service life thereof. Therefore, in some embodiments, the cooling effect of the cooling chamber 221 can be used to additionally cool the driving member 234 and the heat insulation valve core 233.

In some embodiments, the insulation core 233 and the driving member 234 are disposed inside the refrigeration compartment 221, and the cool air in the refrigeration cavity 2211 can cool the isolation valve assembly 230.

Further, referring to fig. 6-10, in some embodiments, the interlayer sheet 2216 further encloses with the cover 231 a second cooling cavity 2213, the second cooling cavity 2213 is communicated with or separated from the first cooling cavity 2212, and the insulation valve core 233 and the driving member 234 are disposed in the second cooling cavity 2213. In the embodiment shown in fig. 6-10, the first cooling compartment 2212 is in communication with the second cooling compartment 2213, for example, through a gap between the interlayer sheet 2216 and the base 2214, so that part of the cool air can flow into the second cooling compartment 2213, thereby reducing the temperature in the second cooling compartment 2213, and thus cooling the thermal insulation valve core 233, the driving member 234 and the cover 231.

Of course, in other embodiments, the first refrigeration cavity 2212 and the second refrigeration cavity 2213 may be sealed and separated, and they are not communicated, so as to ensure that the cold air in the first refrigeration cavity 2212 can be delivered into the cooking cavity 122 as much as possible, thereby improving the cooling efficiency. At this time, although the first refrigeration cavity 2212 is not communicated with the second refrigeration cavity 2213, the cold air in the first refrigeration cavity 2212 can still be transferred into the second refrigeration cavity 2213 through the interlayer plate 2216 itself, so as to reduce the temperature in the second refrigeration cavity 2213 to a certain extent, and the cold air is used for cooling the heat insulation valve core 233, the driving member 234 and the cover 231.

Divide into first refrigeration chamber 2212 and second refrigeration chamber 2213 with refrigeration chamber 2211, not only can make the air conditioning carry more independently, but also can utilize the low temperature of air conditioning to cool down thermal-insulated case 233, driving piece 234 and lid 231, also do benefit to the compactness of whole refrigeration assembly 220 structure simultaneously, be favorable to the reduction of volume.

To enable further volume reduction, with continued reference to fig. 6-10, in some embodiments, the shelf panel 2216 has a recessed slot 2219 recessed into the interior of the first refrigeration cavity 2212, the recessed slot 2219 being adapted to receive the actuator 234. In some embodiments, the depression 2219 is raised into the first cooling cavity 2212 so that it extends into the first cooling cavity 2212, thereby cooling the driving member 234 with the cool air in the first cooling cavity 2212. For example, in the illustrated embodiment, the concave slot 2219 is provided protruding towards the first refrigeration cavity 2212, in the middle of the cooling portions 2221 or in the gaps between adjacent cooling portions 2221. Moreover, the concave slot 2219 is protruded towards the first refrigeration cavity 2212, and the space in the first refrigeration cavity 2212 can be fully utilized to accommodate the driving member 234, so that an extra large space is not required to be additionally arranged in the axial direction of the first air outlet 2321 to accommodate the driving member 234, the size of the refrigeration assembly 220 in the axial direction c1 of the first air outlet 2321 is further reduced, and the refrigeration assembly 220 is more beneficial to realizing lightness and thinness in the direction.

To communicate the first cooling cavity 2212 with the first vent 232, please continue to refer to fig. 18, in some embodiments, a second vent 2219 is disposed on the partition plate 2216, and the second vent 2219 communicates with the corresponding first vent 232 to allow the gas to pass through. The second vent 2219 and the corresponding first vent 232 may be directly connected to each other, or may be connected to each other through other connecting structures.

With continued reference to fig. 6-10, in some embodiments, for the number and type of the first air vents 232, the second air vents 2219 can be divided into a second air inlet 2218 and a second air outlet 2217, the second air inlet 2218 is communicated with the first air inlet 2322 of the cover 231, and the second air outlet 2217 is communicated with the first air outlet 2321 of the cover 231. Of course, when the cover 231 has only the first outlet port 2321, the second air vent 2219 may have only the second outlet port 2217 and communicate with the first outlet port 2321 of the cover 231.

With continued reference to fig. 6, in some embodiments, a valve core movement gap 237 may be provided between the second vent port 2219 and the first vent port 232, and the thermal insulation valve core 233 moves in the valve core movement gap 237 to cut off and open the passage between the first vent port 232 and the corresponding second vent port 2219.

Of course, in other embodiments, the refrigeration cavity 2211 may be divided into more sub-refrigeration cavities, each of which is used to house different components and structures. Alternatively, in other embodiments, the refrigeration cavity 2211 may not be divided into a plurality of sub-refrigeration cavities, that is, the refrigeration cavity 2211 is an interconnected cavity, for example, the first refrigeration cavity 2212 in fig. 6 is closed to be used as an independent refrigeration cavity 2211, in this case, the isolation valve assembly 230 may be disposed in the first refrigeration cavity 2212, or may be installed on the partition board 2216 according to the present structure, in this case, the partition board 2216 serves as the compartment wall 121 of the refrigeration compartment 221.

While some embodiments have been described above in which isolation valve assembly 230 is located within refrigeration compartment 221, isolation valve assembly 230 may also be located outside of refrigeration compartment 221, see FIG. 12, in some embodiments. The heat insulation valve core 233 and the driving member 234 are disposed outside the refrigerating compartment 221, and the cover 231 is a part of the refrigerating compartment 221 or fixed to the refrigerating compartment 221.

When isolation valve assembly 230 is disposed outside refrigeration compartment 221, in some embodiments, the side of refrigeration compartment 221 facing drive member 234 may also have a recessed slot 2219, the recessed slot 2219 is recessed from the side of cooking chamber 122 to the interior of refrigeration chamber 2211, and drive member 234 is embedded in recessed slot 2219. The back of the concave slot 2219 protrudes into the refrigeration cavity 2211, so that the driving member 234 can be cooled by the cool air in the refrigeration cavity 2211, and the driving member 234 can be accommodated in the space of the refrigeration cavity 2211, thereby improving the compactness of the structure and reducing the axial size of the vent.

Further, the first vent 232 may be directly communicated with the cooking chamber 120, or may be communicated with the cooking chamber 120 through a transition structure. Referring to fig. 5 and 18, in some embodiments, the first vent 232 is inserted directly into the cooking cavity 122 of the cooking chamber 120. The end of the first air vent 232 inserted into the cooking chamber 122 may be provided with a strainer 2323 to prevent food material residue from entering the first air vent 232. Of course, in other embodiments, the first air vent 232 may also interface with an interface on the cooking chamber 120, or be inserted into the first air vent 232 by an interface on the cooking chamber 120.

Referring to fig. 6, in some embodiments, the cover 231 itself may be a one-piece structure, such as a one-piece metal or other material. The first vent 232 may be disposed through the integrally formed structure. In addition, the cover 231 can also be assembled and assembled by a plurality of components, referring to fig. 6, in some embodiments, the cover 231 includes a seat body 2311 and a butt joint 2312 disposed on the seat body 2311, and the first air vent 232 is disposed on the butt joint 2312 in a penetrating manner. The pair of joints 2312 may be one or more according to the number and type of the first vents 232. The cover 231 can be connected to the cooking chamber 120 through the docking head 2312, as shown in fig. 5 and 18, one end of the docking head 2312 is directly inserted into the cooking chamber 120, and the other end of the docking head 2312 is used to directly or indirectly connect to the refrigeration cavity 2211.

Further, referring to fig. 19 and 20, in some embodiments, the first air vent 232 may be divided into a first air outlet 2321 and a first air inlet 2322, and at this time, the same driving member 234 is used to control the thermal insulation valve core 233 to open and close the first air inlet 2322 and the first air outlet 2321 synchronously. By using the same driving member 234 to control the thermal insulation valve core 233 to synchronously open and close the first air inlet 2322 and the first air outlet 2321, the number of the driving members 234 can be saved, thereby simplifying the structure, and facilitating the structural design to be more compact and the volume to be smaller.

Of course, in other embodiments, different driving members 234 and different heat insulation valve cores 233 may be provided for the first air outlet 2321 and the first air inlet 2322, respectively, to perform on-off control.

Further, in some embodiments, the wall 121 has a butt outer wall for installing the isolation valve assembly 230, the isolation valve assembly 230 is located outside the butt outer wall, and the axis c1 of the first air vent 232 is perpendicular to or forms an acute angle with the plane of the butt outer wall, so that the volume of the whole apparatus on the side of the butt outer wall in the axial direction of the first air vent 232 can be reduced while the cooling and refreshing functions are provided. Wherein either side of the bin wall 121 may serve as an abutting outer wall, such as at least one of the back side wall 124, the left side wall 125, the right side wall 126, the top wall 128, and the bottom wall 127 having an abutting outer wall, as long as there is no conflict with other structures.

Referring to fig. 18, in some embodiments, the left sidewall 125 has an abutting outer wall 129, i.e., the refrigeration assembly 220 is disposed on the left sidewall 125. In the illustrated embodiment, the axis of the first vent 232 is perpendicular to the left sidewall 125, although the two may be at an acute angle. Referring to fig. 5 and 18, in some embodiments, the cooling assembly 220 interfaces with the cooking chamber 120 through the cover 231. In order to provide good thermal insulation, in some embodiments, a thermal insulation layer 235 (made of thermal insulation material such as thermal insulation cotton) is disposed between the cover 231 and the cooking chamber 120 for thermal insulation.

Further, referring to fig. 9 and 19, in some embodiments, in order to further increase the heat insulation effect of the refrigeration assembly 220 and the cooking chamber 120, the cover 231 is filled with a second heat insulation layer 236 (made of heat insulation material such as heat insulation cotton) and is heat insulated by the second heat insulation layer 236.

Furthermore, in some other embodiments, at least one of the left and

right side walls

125, 126 has an abutting outer wall 129, which will allow the overall apparatus to have a smaller dimension in the left-right direction (defined as the width direction of the apparatus in this embodiment) relative to the manner in which the other refrigeration components 220 are mounted to the left and

right side walls

125, 126. At this time, the heat insulation valve core 233 can move relative to the cover 231 in the front-rear direction or the up-down direction of the abutting outer wall 129. In this embodiment, the food material taking and placing opening 123 is defined as front, the back side wall 124 is rear, the left side wall 125 is left, the right side wall 126 is right, the top wall 128 is up, and the bottom wall 127 is down. These directional terms are only used to clearly illustrate the relative position relationship between the features, and the essence is to emphasize the relative position of the features, so that the directional terms may have different names according to the direction definitions.

When the cooling module 220 is disposed on the back side wall 124, compared to the other cooling modules 220 and the back side wall 124, the size of the device in the front-back direction (defined as the depth direction of the device in the present embodiment) can be further reduced by this structure; when the refrigeration component 220 is disposed on the top wall 128 or the bottom wall 127, for the installation manner of the other refrigeration component 220 and the top wall 128 or the bottom wall 127, the size of the apparatus in the up-down direction (defined as the height direction of the apparatus in the present embodiment) can be further reduced by this structure.

To make the structure more compact, an insulation spool passage 2388 is left between drive member support 2387 and cover 231, and insulation spool 233 is positioned in insulation spool passage 2388 and passes through drive member support 2387. In the embodiment shown in fig. 19 and 20, the actuator bracket 2387 is mounted to the cover 231, although in other embodiments, the actuator bracket 2387 may be mounted to other structures, such as the shelf 2216 or the base 2214 of the refrigeration compartment 221.

Referring to fig. 19 and 20, in some embodiments, a pressing seat 240 is correspondingly disposed at one end of the first air vent 232, and a valve core movement gap 237 for the heat insulation valve core 233 to enter and exit is left between the pressing seat 240 and the cover 231. The second elastic element 2392 is directly or indirectly connected to the pressing seat 240 and provides an elastic restoring force to the pressing seat 240 to drive the pressing seat 240 to move toward the cover 231, so as to press the thermal insulation valve core 233 against the first venting hole 232 when the thermal insulation valve core 233 is in the closed position.
