The mounting seat 100 forms a receiving space 300 for the pot body. The refrigerating part 400 is arranged on the mounting base 100 and used for cooling the pot body. The flexible heat exchange layer 500 is disposed at a side of the refrigeration part 400 facing the accommodating space 300, the flexible heat exchange layer 500 is in contact with the refrigeration part 400, and the flexible heat exchange layer 500 is configured to: the flexible heat exchange layer 500 is attached to the pot body in case that the accommodating space 300 has the pot body.

Besides, the pot body may further include a heat insulation cover (not shown), wherein the heat insulation cover is generally fixedly mounted on the mounting base 100, and the inner pot 200 may be fixed on the mounting base 100 or detachably disposed in the accommodating space 300. Therefore, the phrase "the flexible heat exchange layer 500 is attached to the pot body when the accommodating space 300 has the pot body" includes a case where the flexible heat exchange layer 500 is attached to the heat-insulating cover, a case where the flexible heat exchange layer 500 is attached to the inner pot 200 when the inner pot 200 is located in the accommodating space 300, and a combination of the above cases. For the convenience of the inner pot 200 (e.g., for cleaning), the inner pot 200 may be detachably disposed in the accommodating space 300.

According to the cooking base of the embodiment of the utility model, the flexible heat exchange layer 500 is arranged on one side of the cooling component 400 facing the accommodating space 300, and because the flexible heat exchange layer 500 has the characteristic of deforming under stress, the flexible heat exchange layer 500 can be in full contact with the pot body, so that the flexible heat exchange layer 500 is attached to the pot body when the cooking appliance works, the heat conduction efficiency between the cooling component 400 and the pot body is ensured, and the cooling effect is improved.

According to an embodiment of the present invention, the mounting base 100 is configured in a manner related to the product type of the cooking appliance. For example, when the cooking appliance is an electric cooker, a pressure cooker or an electric stewpot, the mounting base 100 is generally provided with a groove 101, and the pot body is placed in the accommodating space 300 inside the groove 101, and the accommodating space 300 of the pot body is a relatively closed space. When the cooking appliance is an induction cooker, the mounting base 100 is generally provided with a temperature control panel, the accommodating space of the pot body is a space formed outside the temperature control panel, and the accommodating space of the pot body is a relatively open space. Of course, the type of cooking appliance is not limited by the examples herein. The drawings are only described by way of example in the case that the cooking appliance is an electric cooker, a pressure cooker or an electric stewpan, and it should be understood that the drawings do not limit the embodiments of the present invention.

According to the embodiment of the present invention, the specific structural form of the refrigeration part 400 is not limited as long as the pot body can be cooled. For example, the refrigeration unit 400 may be in the form of a semiconductor refrigeration sheet, an evaporation coil 402, and a refrigeration belt 800 (see fig. 3 to 9) including a refrigerant microchannel 805, and is not limited to the examples herein. The refrigerant may be a refrigerant or a coolant.

Referring to fig. 1 and 2, the cooking base includes a heat conduction mounting plate 600, the heat conduction mounting plate 600 is used for fixing the refrigeration component 400, and the heat conduction mounting plate 600 is fixed on a side of the flexible heat exchange layer 500 facing away from the accommodating space 300 (i.e. when the inner pot 200 is located in the accommodating space 300, the heat conduction mounting plate 600 is fixed on a side of the flexible heat exchange layer 500 facing away from the inner pot 200). Furthermore, the heat conduction mounting plate 600 can support the flexible heat exchange layer 500, so that the flexible heat exchange layer 500 can maintain a specific shape, and the flexible heat exchange layer 500 can be attached to the pot body. Here, the positional relationship between the refrigeration component 400 and the heat conductive mounting plate 600 is not limited as long as the refrigeration component 400 can be fixed to the flexible heat exchange layer 500 through the heat conductive mounting plate 600. For example, the refrigeration unit 400 may be completely wrapped inside the thermal conductive mounting plate 600, and the refrigeration unit 400 may be fixed to the surface of the thermal conductive mounting plate 600.

According to the embodiment of the present invention, the heat conducting mounting plate 600 may be a metal plate, for example, an aluminum plate or a copper plate, so as to ensure that the heat conducting mounting plate 600 has both heat conducting performance and certain rigidity.

According to the embodiment of the present invention, the fixing manner between the flexible heat exchange layer 500 and the heat conductive mounting plate 600 is not limited, and for example, the two may be bonded, snapped, or screwed. In fig. 2, a locking groove 501 is formed on a side of the flexible heat exchange layer 500 facing the heat conductive mounting board 600, and the heat conductive mounting board 600 is fitted into the locking groove 501. Wherein, due to the flexible nature of the flexible heat exchange layer 500, the reliability of the assembly between the heat conducting mounting plate 600 and the flexible heat exchange layer 500 may be further ensured.

According to an embodiment of the present invention, the cooking base of the cooking appliance further comprises a heat shield 700. The heat shield 700 is disposed on a side of the refrigeration component 400 facing away from the flexible heat exchange layer 500, with the refrigeration component 400 located between the heat shield 700 and the flexible heat exchange layer 500. Through the arrangement of the heat shield 700, the outward diffusion of the cold energy of the refrigeration component 400 can be prevented, the heat exchange between the refrigeration component 400 and other components of the cooking appliance is avoided, and the energy waste is avoided. In addition, the heat shield 700 may also protect the refrigeration component 400. And through the cooperation between heat exchanger 700 and the flexible heat exchange layer 500, can be so that refrigeration part 400 is in a relatively inclosed space, avoid frosting at refrigeration part 400's surface, perhaps, can reduce or even stop the production of comdenstion water, consequently can guarantee refrigeration part 400 and normally work, need not to shut down and change frost, improve user experience.

In one embodiment, the heat shield 700 is in the form of a polyurethane foam, vacuum insulation panel, or the like. Of course, the specific form of the heat shield 700 is not limited as long as the heat insulating effect can be achieved. In addition, a support cover 110 can be arranged outside the heat shield 700 to support the heat shield 700, the refrigeration component 400 and the like; of course, the support cover 110 may not be provided.

In fig. 2, a heat shield 700 is secured to a thermally conductive mounting plate 600. The upper end and the lower extreme of thermal shroud 700 and heat conduction mounting panel 600 are all sealed the laminating, and refrigeration part 400 is fixed in between thermal shroud 700 and the heat conduction mounting panel 600, and then can avoid refrigeration part 400 and outside air to take place heat exchange, avoid refrigeration part 400 to frost, reduce or even stop the production of comdenstion water. Of course, the structural forms of the heat shield 700 and the heat conductive mounting plate 600 are not limited by way of example herein, and the heat shield 700 may also be directly fixed with the flexible heat exchange layer 500, and the heat conductive mounting plate 600 is then fixed between the flexible heat exchange layer 500 and the heat shield 700.

According to the embodiment of the utility model, the mounting base 100 is provided with the groove 101, the accommodating space 300 is formed in the groove 101, and the pot body comprises the heat preservation cover arranged on the upper part of the side wall of the groove 101. Under the condition, when the inner pot 200 is placed in the accommodating space 300, the cooking effect of the cooking appliance can be ensured through the arrangement of the heat-insulating cover. Wherein, the heat preservation cover is generally arranged corresponding to the upper part of the side wall of the inner pot 200, and certainly, the situation that the heat preservation cover is arranged corresponding to the whole side wall of the inner pot 200 or even corresponding to the bottom plate of the inner pot 200 is not eliminated.

According to an embodiment of the present invention, the "flexible heat exchange layer 500 fits the pot body in case the accommodating space 300 has the pot body" includes at least the following forms:

in a first form: the pot body includes the heat preservation cover, and keeps warm and cover fixed mounting in mount pad 100, and at least one of flexible heat exchange layer 500 laminating heat preservation cover and interior pot 200, wherein, the prerequisite of pot 200 in the laminating of flexible heat exchange layer 500 is that interior pot 200 is placed in the accommodation space. The first form has the following different cases:

in one case, the refrigeration component 400 and the flexible heat exchange layer 500 are disposed on a side of the thermal insulation cover facing the mounting base 100, the flexible heat exchange layer 500 is located between the refrigeration component 400 and the thermal insulation cover, and the flexible heat exchange layer 500 is attached to the thermal insulation cover. The side of the heat-insulating cover facing the mounting base 100, that is, the outer side of the heat-insulating cover, that is, the side of the heat-insulating cover away from the center of the accommodating space 300, is referred to as the "outer side of the heat-insulating cover". Under this kind of condition, refrigeration part 400 fully contacts through gentle heat exchange layer 500 and heat preservation cover, and gentle heat exchange layer 500 can laminate with the heat preservation in the time of the work, and then can guarantee the heat conduction efficiency between refrigeration part 400 and the heat preservation cover to the food in the fast cooling culinary art chamber.

In another case, the refrigeration unit 400 is disposed at least one of a lower portion of a sidewall of the recess 101 and a bottom wall of the recess 101, the pot body includes the inner pot 200, and the flexible heat exchange layer 500 is configured to: in a case where the inner pot 200 of the pot body is placed in the accommodating space 300, the flexible heat exchange layer 500 is located between the refrigeration part 400 and the inner pot 200, and the flexible heat exchange layer 500 is attached to the inner pot 200. In this case, the refrigeration part 400 is fully contacted with the inner pot 200 through the flexible heat exchange layer 500, and the flexible heat exchange layer 500 can be attached to the inner pot 200 during operation, so that the heat conduction efficiency between the refrigeration part 400 and the inner pot 200 can be ensured, and the food in the cooking cavity can be rapidly cooled.

In still another case, the refrigeration unit 400 and the flexible heat exchange layer 500 are disposed corresponding to the heat-insulating cover and the inner pan 200, that is, a portion of the refrigeration unit 400 is disposed corresponding to a side of the heat-insulating cover facing the mounting seat 100, and the remaining portion of the refrigeration unit 400 is attached to the inner pan 200 through the flexible heat exchange layer 500 in a state that the inner pan 200 of the pan body is placed in the accommodating space 300. Thus, the cooling member 400 sufficiently contacts the heat-retaining cover and the inner pan 200 through the flexible heat exchange layer 500 to rapidly cool the food in the cooking cavity.

In a second form: the pot body does not include the heat preservation cover, and when the interior pot 200 of the pot body was located accommodation space 300, pot 200 was laminated in flexible heat exchange layer 500.

According to the embodiment of the present invention, when the pot body includes the heat-insulating cover, the cooling part 400 and the flexible heat exchange layer 500 can cool the inner pot 200 through the heat-insulating cover, can directly cool the inner pot 200, or can be a combination of the two. When the pot body does not include the heat insulation cover, the refrigeration part 400 and the flexible heat exchange layer 500 may directly refrigerate the inner pot 200, and the refrigeration part 400 and the flexible heat exchange layer 500 may be disposed at any position of the inner pot 200, for example, the refrigeration part 400 and the flexible heat exchange layer 500 may be disposed corresponding to a side wall of the inner pot 200, a bottom plate of the inner pot 200, or both the side wall and the bottom plate of the inner pot 200. When the refrigeration part 400 and the flexible heat exchange layer 500 directly refrigerate the inner pan 200, and the inner pan 200 is detachably mounted in the accommodating space 300, since the refrigeration part 400 is provided with the flexible heat exchange layer 500, in the process of dismounting, the hard contact between the inner pan 200 and the refrigeration part 400 in the related art becomes the soft contact between the flexible heat exchange layer 500 and the inner pan 200, so that the dismounting of the inner pan 200 is smoother.

According to an embodiment of the utility model, the flexible heat exchange layer 500 is a thermally conductive silicone rubber layer. The heat conducting silicone rubber layer has a larger heat conducting coefficient, and can ensure the heat conducting efficiency between the refrigeration part 400 and the pot body. In addition, the heat-conducting silicon rubber has better cold and hot impact resistance, and does not generate obvious deformation such as contraction, expansion and the like under the condition of temperature change of-30 ℃ to 130 ℃, so that the heat-conducting silicon rubber layer can be always ensured to be fully contacted with the pot body under different working conditions.

In addition, the heat conduction silicone rubber layer has certain hardness, and when the heat conduction silicone rubber layer is arranged corresponding to the inner pot 200, the heat conduction silicone rubber layer can be prevented from being worn in the process of taking and placing the inner pot 200, the structural form of the heat conduction silicone rubber layer is maintained, and the adhesion between the heat conduction silicone rubber layer and the inner pot 200 is ensured. In addition, the heat-conducting silicone rubber layer does not wear the coating on the surface of the inner pot 200, and is not easy to age. It should be understood that the flexible heat exchange layer 500 may take other forms than the heat conductive silicone rubber layer.

In one embodiment, the hardness of the flexible heat exchange layer 500 may be in the range of 40 (kgf/mm)²)～70(kgf/mm²) The hardness is referred to herein as shore. The thermal conductivity of the flexible heat exchange layer 500 may be 1W/(mK) to 3W/(mK). The thickness of the flexible heat exchange layer 500 is 0.1 mm-20 mm, and with reference to fig. 2 and 10, the thickness of the flexible heat exchange layer 500 is thinner at the portion matching the inner pot 200, and the thickness of the other portion is smaller so as to match the shape of the inner pot 200; it is clear that the flexible heat exchange layer 500 may also be equally thick throughout. Of course, the thickness of the flexible heat exchange layer 500 may be as thin as possible while ensuring structural strength. When the coefficient of the flexible heat exchange layer 500 is in the above interval, it can be ensured that the inner pan 200 and the flexible heat exchange layer 500 are sufficiently contacted, thereby ensuring the heat conduction efficiency of the refrigeration part 400. The flexible heat exchange layer 500 of the embodiment of the present invention may be made of any conventional material as long as it is within the above range.

According to an embodiment of the utility model, the surface of the flexible heat exchange layer 500 may be provided with an oleophobic coating to ensure the oleophobicity of the flexible heat exchange layer 500.

According to an embodiment of the present invention, the cooling part 400 is formed with a cooling passage 401 through which a refrigerant flows. And then the cooling to the food in the culinary art chamber is realized through the refrigerant that circulates in refrigeration passageway 401. A refrigerant capable of performing phase change may be introduced into the refrigeration channel 401, and heat of the food is taken away by the phase change of the refrigerant. Of course, the cooling channel 401 may also be filled with a cooling medium having a temperature lower than the temperature of the food in the cooking cavity, so that heat exchange occurs between the cooling medium and the food in the cooking cavity.

According to an embodiment of the present invention, the refrigerating part 400 includes an evaporation coil 402, and the inside of the evaporation coil 402 forms a refrigerating passage 401. At least part of the liquid refrigerant in the evaporating coil 402 is evaporated into gaseous refrigerant, and absorbs the external heat to cool the food in the cooking cavity.

In one embodiment, the evaporator coil 402 is coiled in multiple turns along the height of the pot. The evaporating coil 402 may be, but is not limited to, a copper tube or an aluminum tube having a relatively good heat exchange effect and bending strength.

According to the embodiment of the present invention, referring to fig. 3 to 9, the refrigeration component 400 includes a refrigeration band 800, and the refrigeration channel 401 is a plurality of parallel micro channels 805 formed inside the refrigeration band 800. Here, "parallel" includes parallel and the case where the directions of extension are substantially the same although they are not parallel. For example, if the angle between two microchannels 805 is not greater than 30 °, then two microchannels 805 may be considered parallel. Liquid refrigerant also flows in the micro-channel 805, and when the refrigerating unit 400 operates, at least part of the liquid refrigerant is evaporated to become gaseous refrigerant, and meanwhile, external heat is absorbed, so that the temperature of food in the cooking cavity is reduced. The difference between the refrigeration zone 800 and the evaporation coil 402 is that the cross-sectional dimension of the micro-channel 805 in the refrigeration zone 800 is much smaller than the cross-sectional dimension of the evaporation coil 402, and thus, less refrigerant flows through the micro-channel 805. Meanwhile, as the plurality of micro channels 805 are parallel, the surface area of the refrigerating strip 800 is far larger than that of the evaporating coil 402 under the condition of the same refrigerant, and the refrigerating component 400 is favorable for saving the refrigerant and improving the heat exchange efficiency by adopting the form of the refrigerating strip 800. In addition, the refrigeration band 800 including the micro-channels 805 also has the characteristics of compact structure and lightness.

Referring to fig. 3 to 5 and fig. 7 to 9, the refrigerating tape 800 includes a flat outer tube 801 and a partition disposed inside the outer tube 801, and the plurality of microchannels 805 are separated by the partition. Of course, instead of providing a partition in the outer tube 801 to form a plurality of microchannels 805, it is also possible to form the microchannels 805 in separate tubes and to provide a plurality of tubes in parallel to obtain a plurality of microchannels 805 in parallel.

In fig. 5 to 8, the separator includes a support plate 803 and an inner coil 802 wound around the support plate 803, and a microchannel 805 is formed between the inner coil 802 and the inner wall of the outer tube 801, or a microchannel 805 is formed between the inner coil 802, the support plate 803 and the inner wall of the outer tube 801. Wherein the support plate 803 may facilitate installation of the inner coil 802. On this basis, as long as the support plate 803 is mounted inside the outer tube 801, parallel microchannels 805 can be formed in the outer tube 801. The inner coil 802 may be coiled on both sides of the support plate 803, and further, microchannels 805 may be formed on both sides of the support plate 803. Of course, the inner coil 802 may also be coiled along the surface of one of the sides of the support plate 803, such that the micro-channels 805 are formed in one of the sides of the support plate 803. The inner coil 802 may be, but is not limited to, a metal wire, so that the space inside the outer tube 801 is divided while the coiling is facilitated.

In one embodiment, the cross-section of the inner coil 802 gradually increases from the outer tube 801 to the support plate 803. At this time, the micro channel 805 is formed outside the outer tube 801 (with respect to the center of the outer tube 801), the middle portion of the outer tube 801 is filled with the support plate 803 and the inner coil 802, so that the refrigerant can be further saved, and the cross section of the portion of the inner coil 802 close to the outer tube 801 is small, so that the sufficient contact between the refrigerant and the outer tube 801 is not affected, and the heat exchange effect of the micro channel 805 is ensured under the condition of saving the refrigerant. For example, in FIG. 7, the cross-section of the inner coil 802 is triangular, but the cross-section of the inner coil 802 may also be trapezoidal or other shapes. To save energy, the supporting plate 803 and the inner coil 802 may be made of a material that is not thermally conductive or has poor thermal conductivity.

In another embodiment, referring to fig. 3 and 4, the divider comprises a divider plate 804 in sealing contact with the inner wall of the outer tube 801, the divider plate 804 and the inner wall of the outer tube 801 defining a microchannel 805 therebetween. In this case, the microchannel 805 is obtained by dividing the inner space of the outer tube 801 directly by the partition plate 804, and its structure is relatively simple. In addition, the cooling belt 800 may be made of aluminum and integrally formed through a drawing process; alternatively, the cooling belt 800 may be made of aluminum and integrally formed by an extrusion casting process; still alternatively, the cooling belt 800 may be combined by both drawing and extrusion casting processes.

In one embodiment, the cross section of the partition 804 inside the outer tube 801 at the joint with the outer tube 801 is larger than that at other places, so that the joint between the outer tube 801 and the partition 804 has a larger heat storage performance, and the heat exchange effect of the refrigeration band 800 can be ensured.

In fig. 3 and 4, the relationship between the first dimension a and the second dimension b of the microchannel 805 satisfies a: b is 0.2 to 3. The first dimension a is not too large, so as to avoid the bulging deformation of the outer tube 801 under the pressure of the refrigerant. Specifically, the first dimension a and the second dimension b may be selected based on different refrigerant pressures.

In yet another embodiment, referring to FIG. 9, the dividers include an inner coiled tube 802, with microchannels 805 formed between the inner coiled tube 802 and the inner wall of the outer tube 801.

According to an embodiment of the utility model, the micro channel 805 is a spiral channel, and the spiral channel is adapted to extend along the height direction of the pot body and to be coiled to the outer surface of the pot body. Correspondingly, the cooling belt 800 extends along the height direction of the pan body and is wound to the outer surface of the pan body, so that a plurality of parallel micro-channels 805 therein are wound to the outer surface of the pan body. Of course, the cooling belt 800 may be set wide enough, and then the cooling belt 800 and the micro-channel 805 inside it may be sufficiently contacted with the pan body without being coiled.

According to an embodiment of the present invention, the inner surface of the micro channel 805 is provided with ribs 806 to enhance the heat exchange of the micro channel 805 by changing the flow direction of the refrigerant or increasing the heat exchange area of the refrigerant. Wherein the structural form and distribution of the ribs 806 are not limited. For example, the ribs 806 may spiral around the inner surface of the microchannel 805 and extend along the length of the microchannel 805. As another example, the ribs 806 extend in a direction parallel to the direction of the central axis of the microchannel 805. In addition, the ribs 806 may be perpendicular to the inner surface of the microchannel 805 in which they are located, for example, as shown in fig. 4, or may be obliquely disposed on the inner surface of the microchannel 805 in which they are located.

According to the embodiment of the present invention, the height of the rib 806 is smaller than the distance from the surface of the rib 806 to the center line of the micro channel 805, so that the interference between the ribs 806 disposed oppositely can be prevented.

According to an embodiment of the present invention, the cross-sectional shape of the micro-channel 805 is not limited, and may be, for example, circular, rectangular, triangular, etc.

In one embodiment, the ribs 806 have a height of 0.1mm (millimeters) to 3 mm; the cross-section of the micro-channel 805 is circular and the aperture of the micro-channel 805 is 0.5mm²(square millimeter) to 40mm²。

On this basis, when the cooking base includes the heat shield 700, a mounting groove 601 may be formed on the heat shield 700, so that the evaporation coil 402 may be fixed between the heat shield 700 and the heat-conducting mounting plate 600, thereby ensuring the reliability of the mounting of the evaporation coil 402. When the cross section of the evaporation coil 402 is circular and the edge of the cross section of the installation groove 601 is arc-shaped, if the radius of the evaporation coil 402 is not greater than the depth of the installation groove 601, the evaporation coil 402 can be conveniently installed in the installation groove 601.

When the compressor is started, the gaseous refrigerant enters the condenser from the outlet of the compressor, is liquefied at the condenser and becomes a liquid refrigerant, and then the liquid refrigerant enters the evaporation coil 402 through the throttling element and is evaporated and absorbs heat at the evaporation coil 402. In addition, valves are provided in the communication lines between the compressor, condenser, throttling element and the evaporator coil 402 to enable on-off control and regulation of the lines.
