Of course, the food processing device can also be provided with a self-heating function.

It can be seen that the heating part 1 and the cooling part 2 of the integrated cooling and heating device 100 of the present invention are capable of operating independently of each other, including the hot pot 11 and the cold pot 21 operating simultaneously or individually. Therefore, the cold and hot integrated device 100 can adapt to the drinking habits of different crowds, and improves the use convenience of the user, thereby greatly improving the use experience of the user.

In addition, since the types of the hot pot 11 and the cold pot 21 are not limited, in some embodiments, the hot pot 11 and the cold pot 21 may be respectively fixedly inserted into the hot pot insertion groove 12 and the cold pot insertion groove 24, or both the hot pot 11 and the cold pot 21 may be provided in a structure that can be taken by a user, or in a structure that one of the hot pot 11 and the cold pot 21 is fixedly inserted and the other one is taken. Therefore, the integrated cooling and heating device 100 of the present invention can adapt to the drinking habits of different people and the usage habits of different users.

In some embodiments, to ensure the stable insertion of the cooling pot 21, a cooling guide sleeve 22 may be installed in the cooling pot insertion groove 24, and the inner diameter of the cooling guide sleeve 22 is slightly larger than the outer diameter of the cooling pot inner container 21c of the cooling pot 21. Therefore, when the cold pot inner container 21c is at least partially inserted into the sleeve cavity of the cold guide sleeve 22, the cold pot inner container 21c does not shake, and the cold pot inner container has a stable installation structure.

In addition, since the cold guiding sleeve 22 has cold guiding property, it can be used as a cold guiding structure between the cold pot 21 and the refrigeration system. However, in order to increase the cooling efficiency, a cooling medium may be filled between the inner wall of the cooling sleeve 22 and the outer wall of the inner container of the cooling pot inner container 21 c.

In some embodiments, an insulating layer 23 may be disposed in the cold pot insertion slot 24 to provide better insulating effect for the cold pot 21. For example, the heat insulating layer 23 may be disposed between the outer wall of the cold guiding sleeve 22 and the inner wall of the cartridge slot, and the heat insulating layer 23 may be formed as a vacuum heat insulating layer or filled with a heat insulating medium.

When a user rotates the hot pot 11 relative to the hot pot insertion slot 12, the function selection key can be aligned with any insertion slot function key, and the electric connection is realized when the function selection key is aligned with the insertion slot function key, so that the hot pot 11 realizes the function corresponding to the insertion slot function key.

In an embodiment, the cooling end face is attached to the outer bottom wall of the inner container of the cooling kettle inner container 21c, and the heat sink 216 is connected below the heating end face, so as to ensure that the cooling end face of the semiconductor cooling plate 215 can continuously cool, otherwise, the heating end face and the cooling end face can reach thermal balance, thereby reducing the cold guiding effect of the cooling end face.

Further, the cooling and heating integrated device 100 further comprises an inner cooling fan 4 disposed in the inner cavity of the base 3, so that the heat of the cooling fins 216 can be exhausted out of the base 3 at an accelerated speed, and efficient cooling of the cooling end face is ensured.

Based on the above structure, in order to improve the heat dissipation efficiency, heat dissipation holes may be formed in the bottom wall of the base 3, and the heat dissipation holes are preferably disposed below the inner heat dissipation fan 4. More preferably, the axial projection area of the heat dissipation hole is not smaller than the axial projection area of the inner heat dissipation fan, so that the heat dissipation air output is increased, and the heat dissipation efficiency is improved.

Specifically, the cold pot 21 includes a cold pot housing 21a sleeved outside the cold pot inner container 21c, and a pot body insulating layer serving as a heat insulating layer 23 is arranged between the outer peripheral wall of the cold pot inner container 21c and the inner peripheral wall of the cold pot housing 21a, so as to ensure continuous heat insulation of the cold pot 21. Wherein, the kettle body heat-insulating layer can be set as a vacuum heat-insulating layer or filled with phase-change refrigeration media.

In addition, the cold pot 21 further comprises a cold pot cover 21b for covering the cold pot inner container 21 c. A lid thermal insulation layer is provided in the cold lid 21b as a thermal insulation layer 23, and the outer shell of the cold lid 21b is preferably configured as a sealed outer shell, thereby insulating water and heat.

Preferably, the refrigerating part 2 includes a cold guide structure disposed between the cold pot 21 and the refrigerating end surface of the semiconductor refrigerating sheet 215. The refrigerating sheet mounting plane 217 is arranged in the cold guide structure, and the refrigerating end face of the semiconductor refrigerating sheet 215 is attached to the refrigerating sheet mounting plane 217, so that the cold guide area of the refrigerating end face is increased, and the refrigerating efficiency is improved.

In one embodiment, referring to fig. 6-9, the cold conduction structure includes a separate cold conduction element 218 mounted on the outer peripheral wall of the cold conduction sleeve 22. At this time, the cooling plate installation plane 217 is disposed on the independent cooling guide member 218. It can be seen that since the independent cold guiding element 218 is a cold guiding component that can be produced independently of the cold guiding sleeve 22, the production efficiency is high, and it is easy to assemble and replace, and the production cost and the maintenance cost can be reduced.

Specifically, the individual cold guide elements 218 are annular rings and include circumferential inner and outer cold guide walls 218a, 218b, and the cold guide sleeve 22 is a circular sleeve. At this time, the inner cooling guide wall surface 218a and the sleeve outer peripheral wall surface of the cooling guide sleeve 22 are bonded to each other, which is advantageous for increasing the cooling guide area. In addition, a cooling plate mounting plane 217 is formed on the outer cold conducting wall surface 218b, so that the cooling end surface of the semiconductor cooling plate 215 can be smoothly attached.

Further, a cooling guide wall outer convex portion 218c protruding outward is formed on the outer cooling guide wall surface 218b, and a radially outer end surface of the cooling guide wall outer convex portion 218c is formed as a cooling fin mounting plane 217. Or, an inward-concave cold guide wall groove may be formed on the outer cold guide wall surface 218b, a groove bottom wall of the cold guide wall groove may serve as the cooling plate mounting plane 217, and a groove upper side wall and a groove lower side wall of the cold guide wall groove may respectively abut against the upper end and the lower end of the semiconductor cooling plate 215, so as to ensure firm mounting thereof.

Further, the cooling efficiency can be improved by increasing the circumferential contact area and the axial contact area of the inner cooling guide wall surface 218a and the sleeve outer peripheral wall surface of the cooling guide sleeve 22. Preferably, the circumferential length of the inner cold guide wall 218a is at least half the circumferential length of the outer sleeve peripheral wall, and the axial length of the inner cold guide wall 218a is at least 1/3 times the axial length of the outer sleeve peripheral wall.

When the circumferential perimeter of the inner cold-conducting wall surface 218a is greater than or equal to half of the circumferential perimeter of the sleeve outer circumferential wall surface, an interference crimp may be formed between the inner cold-conducting wall surface 218a and the sleeve outer circumferential wall surface to secure the assembly of the separate cold-conducting element 218 and the cold-conducting sleeve 22. Alternatively, a separate cold guide 218 may be provided as a resilient cold guide to resiliently pinch the cold guide sleeve 22.

When the circumferential perimeter of the inner cold-conducting wall 218a is less than half of the circumferential perimeter of the sleeve peripheral wall, the separate cold-conducting element 218 can be fixedly attached to the cold-conducting sleeve 22 by gluing or fasteners, etc.

In another embodiment, referring to fig. 10 and 11, the cold guiding structure includes a cooling plate mounting plane 217 directly formed on the sleeve peripheral wall of the cold guiding sleeve 22, and the cooling end surface of the semiconductor cooling plate 215 can be smoothly attached to the cooling plate mounting plane 217.

Alternatively, a vertically flat wall surface may be formed on the sleeve outer peripheral wall, and the flat wall surface may serve as the cooling fin mounting surface 217. Or, a radially inward concave refrigerating sheet mounting groove is formed on the outer peripheral wall of the sleeve, and a refrigerating sheet mounting plane 217 is formed on the bottom wall surface of the groove of the refrigerating sheet mounting groove. At this moment, the semiconductor refrigeration piece 215 is at least partially embedded into the refrigeration piece mounting groove, and the upper end and the lower end of the semiconductor refrigeration piece 215 are respectively abutted to the upper side wall and the lower side wall of the groove of the refrigeration piece mounting groove, so that stable mounting of the semiconductor refrigeration piece 215 is ensured. Further alternatively, the sleeve outer peripheral wall is formed with a sleeve outer projection 22d projecting outward, and the radially outer end face of the sleeve outer projection 22d is formed as a cooling fin mounting plane 217, which is a structure for facilitating the provision of the heat radiation fins 216 on the heating end face of the semiconductor cooling fin 215.

Preferably, the plane area of the cooling plate mounting plane 217 in the cold conducting structure is not less than the plane area of the cooling end surface, and the structure is beneficial to further increasing the cold conducting contact area of the cooling end surface and the cooling plate mounting plane 217.

Further, the refrigerating part 2 includes a cold pot temperature sensing probe for sensing the temperature of the cold pot 21. The cold pot temperature sensing probe can be an external temperature sensing probe capable of indirectly sensing the temperature of the cold pot, and can also be an internal temperature sensing probe capable of directly sensing the temperature of the cold pot.

By arranging the cold pot temperature sensing probe, the cold and hot integrated device 100 can realize the functions of temperature regulation, supercooling protection or user reminding and the like according to the sensed temperature of the cold pot, and is beneficial to enriching the functions of the cold and hot integrated device 100, so that a user has better use experience.

In one embodiment, referring to fig. 12 and 13, the cold pot temperature sensing probe is an external temperature sensing probe 221 disposed on the outer sleeve bottom wall and/or the outer sleeve peripheral wall of the cold guiding sleeve 22, so as to realize indirect temperature sensing for the cold pot 21. Since the external temperature sensing probe 221 is not in direct contact with the liquid in the cold pot 21 all the time, the sensing method is more clean and sanitary compared with direct temperature sensing, and the drinking safety of the user can be ensured.

Preferably, the outer bottom wall of the sleeve of the cold guide sleeve 22 is formed with a groove 22e of the bottom wall of the sleeve, and the bottom wall of the inner container of the cold pot inner container 21c is formed with a groove 21d of the bottom wall of the inner container. The groove wall of the sleeve bottom wall groove 22e is embedded into the inner container bottom wall groove 21d, and at least part of the external temperature sensing probe 221 is embedded into the sleeve bottom wall groove 22 e. Through embedding external temperature sensing probe 221 in sleeve diapire recess 22e, the cold conducting area between probe and the cold conducting sleeve 22 is bigger, more is favorable to improving the sensing accuracy nature of probe.

More preferably, the cold conducting medium is filled between the sleeve inner bottom wall and the inner container bottom wall of the cold conducting sleeve 22 in the present embodiment, and the top end of the external temperature sensing probe 221 abuts against the top wall of the sleeve bottom wall groove 22 e. Therefore, the top end of the external temperature sensing probe 221 directly contacts with the top wall of the groove 22e of the bottom wall of the sleeve, so that the sensing accuracy of the probe can be further improved, and the working performance of the cooling and heating integrated device 100 is more reliable.

Further, the outer peripheral wall of the external temperature sensing probe 221 embedded in the sleeve bottom wall groove 22e is abutted to the groove side wall of the sleeve bottom wall groove 22e, so that the outer peripheral wall of the external temperature sensing probe 221 is in complete contact with the groove side wall of the sleeve bottom wall groove 22e, the cold conduction area is maximized, and the sensing accuracy is correspondingly highest.

Preferably, the outer bottom wall of the cold guiding sleeve 22 can be provided with a probe through hole, and at this time, the top end of the external temperature sensing probe 221 passes through the probe through hole and abuts against the bottom wall of the inner container of the cold pot inner container 21 c. Compared with the temperature sensing structure, the temperature sensing accuracy of the external temperature sensing probe 221 in the optimal structure is relatively higher due to the fact that the inner container bottom wall of the inner container 21c of the cold kettle is only arranged between the top end of the external temperature sensing probe 221 in the optimal structure and the inner cavity of the cold kettle at intervals, and a layer of cold conduction structure is omitted.

In another embodiment, referring to fig. 14, the cold pot temperature sensing probe is a built-in temperature sensing probe 220 disposed in the cold pot liner 21c of the cold pot 21. As can be seen, the built-in temperature sensing probe 220 can directly contact the liquid in the inner container 21c of the cooling kettle, so that the sensing method has higher temperature sensing accuracy than indirect temperature sensing.

Preferably, the cold pot 21 includes a cold pot lid 21b for covering the cold pot inner container 21c, and the built-in temperature sensing probe 220 can be installed at the bottom of the cold pot lid 21 b. More preferably, a lower cover protrusion 21e protruding downward is formed on the bottom wall of the cold pot cover 21b, and the built-in temperature sensing probe 220 protrudes downward from the lower cover protrusion 21 e. At this time, by providing the pot lid lower protruding portion 21, the contact area between the built-in temperature sensing probe 220 and the liquid is larger, and the temperature sensing accuracy is further improved.

In addition, a pot lid hollow interlayer 21f for heat insulation and preservation and for installing the electric control board 10 may be formed in the cold pot lid 21b, and the pot lid hollow interlayer 21f is preferably provided as a vacuum interlayer or filled with a heat insulation and preservation medium. Accordingly, the outer shell of the cold pot lid 21b is preferably configured as a sealed outer shell, forming a water-proof and heat-insulating structure.

Preferably, a base boss 33 protruding upwards is formed on the top wall of the base 3, and the cold pot insertion groove 24 is located in the base boss 33, so that the axial size of the cold pot insertion groove 24 is larger, the cold pot 21 with larger volume can be placed, and the disposable refrigerating water or ice making amount is increased.

Preferably, the base projection 33 is square and is provided with a heat dissipating air inlet 34 and a heat dissipating air outlet 35. In order to improve the heat dissipation efficiency, the heat dissipation air inlet 34 and the heat dissipation air outlet 35 may be respectively disposed on adjacent sides of the base protruding portion 33, so that a vertical air duct is formed between the heat dissipation air inlet 34 and the heat dissipation air outlet 35, thereby increasing the air pressure and increasing the heat dissipation speed.

In addition, since the hot can insertion slot 12 and the cold can insertion slot 24 are arranged at an interval, the outer side wall of the hot can insertion slot 12 is preferably arranged to be away from the heat dissipation air inlet 34 and the heat dissipation air outlet 35, so as to prevent the heat dissipation from being affected by a large wind resistance formed near the heat dissipation air inlet 34 or the heat dissipation air outlet 35.

Further, the heat dissipation air inlet 34 is preferably configured to be a circular arch, and a plurality of circular arch-shaped bars are concentrically arranged in the air inlet along the radial direction at intervals, and the heat dissipation air outlet 35 is preferably configured to be a rectangular louver, that is, a plurality of straight-bar-shaped bars are arranged in the air outlet along the vertical direction at intervals. When the heat dissipation air inlet 34 is in a circular arch shape and the heat dissipation air outlet 35 is in a rectangular shutter shape, the wind resistance in the heat dissipation air duct is small, the heat dissipation speed can be increased, and the heat dissipation efficiency can be improved.

In order to be matched with the air inlet and outlet structure capable of forming the vertical air channel, the heat dissipation fan arranged in the inner cavity of the base is a centrifugal heat dissipation fan. The heat dissipation air inlet 34 is communicated with an air inlet end of the centrifugal heat dissipation fan, and the heat dissipation air outlet 35 is communicated with an air outlet end of the centrifugal heat dissipation fan. In other words, when the centrifugal fan rotates, the air flows axially through the air inlet 34 to the air inlet end of the fan and flows radially from the air outlet end to the air outlet 35, so as to form a heat dissipating air channel with a large air pressure.

In addition, a base through hole may be preferably formed in the bottom wall or the side wall of the base 3, so that condensed water accumulated in the inner cavity of the base can be discharged outside through the base through hole, or the base through hole may also be used for auxiliary heat dissipation, or the base through hole may be used for both discharging the condensed water and auxiliary heat dissipation.

In addition, the cold pot 21 can be inserted and fixed in the cold pot insertion groove 24 by means of gluing, buckling or fasteners and the like, so that the assembly stability between the cold pot 21 and the cold pot insertion groove 24 is improved. Further, a sealing element is arranged between the outer peripheral part of the cold pot 21 and the inner peripheral wall of the cold pot insertion groove 24, and is used for heat insulation and water prevention, so that efficient refrigeration of the cold pot 21 is guaranteed.

This portable cold kettle 219 can be convenient for the user and hand-carry when going on a journey, especially can greatly satisfy user's the requirement of drinking in hot summer, and the practicality is higher.

Preferably, the portable cooling container 219 includes an upper holding portion 219a and a lower insertion portion 219b, and the lower insertion portion 219b is inserted into the sleeve cavity of the cooling guide sleeve 22. It can be seen that the portable cooling kettle 219 is divided into an upper holding part 219a convenient for a user to hold and a lower inserting part 219b for cooling, so that the portable cooling kettle can be conveniently carried or cooled by the user at any time.

After the refrigeration of the portable cold pot 219 is completed, the temperature of the peripheral wall of the lower insertion part 219b is low, which is not beneficial for the user to hold. However, since the upper holding portion 219a and the lower insertion portion 219b can be cooled mutually, it is necessary to provide a heat insulating layer as the heat insulating layer 23 on the outer peripheral wall of the upper holding portion 219a to prevent the user from feeling uncomfortable when touching the upper holding portion 219 a.

In order to improve the cooling efficiency, the lower insertion portion 219b may be formed in a cylindrical shape, and the cold guiding sleeve 22 may be formed in a circular sleeve. Wherein, a cold-conducting contact structure is formed between the outer wall of the lower insertion part 219b and the inner wall of the cold-conducting sleeve 22. For example, the cold conductive contact structure may be a cold conductive elastic element covering the inner wall of the cold conductive sleeve 22, and the outer wall of the lower insertion portion 219b is elastically pressed against the inner wall of the cold conductive elastic element. Alternatively, the cold contact structure may be screw threads formed on the outer peripheral wall of the lower insertion portion 219b and the inner peripheral wall of the cold guide sleeve 22 to be engaged with each other, respectively, and the lower insertion portion 219b is engaged with the cold guide sleeve 22 by rotation and cold is guided through the respective peripheral walls. Still alternatively, the cold conducting contact structure may be a movable magnetic strip disposed on the inner wall of the cold conducting sleeve 22, and when the lower insertion portion 219b is inserted into the sleeve cavity of the cold conducting sleeve 22, the inner wall of the movable magnetic strip abuts against the outer wall of the lower insertion portion 219 b.

It can be seen that the cold conducting contact structure is arranged between the outer wall of the lower plug part 219b and the inner wall of the cold conducting sleeve 22, so that the refrigeration efficiency is improved, the lower plug part 219b can be limited, and the assembly between the portable cold pot 219 and the cold conducting sleeve 22 is more stable.

When a large gap exists between the outer wall of the lower plug 219b and the inner wall of the cooling jacket 22, the cooling effect is deteriorated, and the cooling efficiency is affected. Therefore, in order to ensure efficient cooling, a micro switch may be provided in the cold guiding sleeve 22, the micro switch being configured to be triggered when the lower insertion portion 219b is inserted into position with the cold guiding sleeve 22. Alternatively, the cooling jacket 22 may be provided with an infrared sensor device for sensing that the lower plug portion 219b is inserted in place in the cooling jacket 22, and when it is detected that the lower plug portion is not inserted in place, cooling is not allowed. It should be noted that whether the insertion is in place refers to whether the gap between the outer wall of the lower insertion portion 219b and the inner wall of the cooling jacket 22 is small enough, and efficient cooling can be ensured only when the gap is small enough or the above-mentioned cooling contact structure is formed between the outer wall of the lower insertion portion 219b and the inner wall of the cooling jacket 22.

In addition, since the portable cooling kettle 219 needs to be frequently inserted and pulled out, the outer wall of the lower insertion part 219b is a part which is easily worn. Therefore, an abrasion-resistant coating with cold conducting property can be arranged on the outer wall of the lower insertion part 219b, so that the abrasion resistance of the portable cold pot 219 is improved, and the attractiveness of the portable cold pot is ensured.

Preferably, the portable cold pot 219 includes a cold pot lid 21b, and a pot lid insulating layer is provided in the cold pot lid 21b as the heat insulating layer 23. When the user needs to take the portable cold pot 219 out, the heat insulation and preservation structure can play a role in preserving heat for a long time.

In addition, as for the heating part 1 of the integrated cooling and heating apparatus 100 of the present invention, it includes a hot pot heating element 13 for heating the hot pot, a connector 14 provided in the hot pot insertion groove 12, and a connector fixing plate 15 for fixedly mounting the connector 14, thereby ensuring that the heating part 1 can perform a heating function.
