In addition, the integrated cooling and heating apparatus 100 may include a food processing apparatus, which may have one or more food processing functions, such as a blending function or a juicing function. In the integrated cooling and heating apparatus 100, the base 3 may be provided with a heating unit 1 or a food processing apparatus which can operate independently of the cooling unit 2, or with both the heating unit 1 and the food processing apparatus, while the cooling unit 2 is provided. 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 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.

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.
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.

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.

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.

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.

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.

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.

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.
