Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like are generally described with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 to 27, the cooling and heating integrated device 100 includes a base 3, a heating part 1 disposed at one end of the base 3, and a cooling part 2 disposed at the other end of the base 3. The heating part 1 includes a hot pot 11 for heating, the hot pot 11 may be a heating container such as an electric kettle or a health preserving kettle, and the cooling part 2 includes a cold pot 21 for cooling liquid, where the cooling function is not limited to a function of cooling water, but also includes a function of making ice or cooling hot water.

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 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.

Specifically, the refrigerating part 2 may include a cold pot insertion groove 24 provided on a top wall of the base 3, the cold pot 21 is inserted in the cold pot insertion groove 24, and the heating part 1 may include a hot pot insertion groove 12 provided on a top wall of the base 3, the hot pot 11 being received in the hot pot insertion groove 12.

In order to ensure the mutual independence between the heating part 1 and the refrigerating part 2, the cold pot insertion slot 24 and the hot pot insertion slot 12 are preferably arranged at intervals. 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, in order to avoid excessive heat exchange between the heating part 1 and the cooling part 2 to affect the cooling or heating efficiency, it is preferable to provide an insulation structure therebetween. For example, a lower cartridge cover 25 can be provided in the cooling part 2, which lower cartridge cover 25 can cover the bottom end opening of the cooling-pot cartridge 24 upwards. In other words, the bottom of the cold pot 21 is located in the cover inner cavity of the lower cover 25, and the lower cover 25 is preferably made of heat insulation material, so as to slow down the heat exchange speed between the hot pot 11 and the cold pot 21.

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 provided in the cold pot insert 24 and/or the insert cover lid 25 to provide better insulation for the cold pot 21. For example, the heat insulating layer 23 may be provided between the outer wall of the cooling jacket 22 and the inner wall of the insertion groove, and the heat insulating layer 23 may be formed as a vacuum insulating layer (see fig. 3) or filled with a heat insulating medium (see fig. 2).

In some embodiments, a stirring device is disposed in the hot pot interior of the hot pot 11 and/or the cold pot interior of the cold pot 21. When the stirring device is provided in the hot pot 11, the heating unit 1 functions as a food processor. When the stirring device is arranged in the cold pot 21, the stirring device can be matched with the ice making function of the cold pot 21 to make the ice slush with better taste.

In some embodiments, the heating part 1 may include a hot pot temperature adjusting device for adjusting the temperature of the hot pot 11, and the cooling part 2 may include a cold pot temperature adjusting device for adjusting the temperature of the cold pot 21. Through setting up temperature regulation apparatus, the user can prepare the boiling water that has specific temperature according to the drinking water requirement of self. Further, the heating part 1 may include an overheat protection device, and the cooling part 2 may include a supercooling protection device, which can ensure safe use of the integrated cooling and heating device 100.

In some embodiments, the inner wall of the insertion slot 12 of the hot pot is provided with a plurality of insertion slot function keys arranged at intervals in the circumferential direction, each insertion slot function key corresponds to a different use function of the hot pot 11, and the outer wall of the hot pot 11 is provided with a function selection key. When the user rotates the kettle 11 relative to the kettle insertion slot 12, the function selection key can align with any insertion slot function key, and the function selection key is electrically connected with the insertion slot function key when aligned, so that the kettle 11 realizes the function corresponding to the insertion slot function key.

Referring to fig. 1 to 27, the refrigerating part 2 may perform refrigeration by a compressor refrigerating system including four major components of a compressor 26, a condenser 27, a throttling element 28 and an evaporator 29, and is preferably disposed in a base inner cavity of the base 3, and in order to ensure enough space in the base inner cavity to install the compressor refrigerating system, a base boss 33 may be disposed on the base 3 to increase the space of the base inner cavity. Wherein the evaporator 29 is used for refrigerating the cold pot 21 and the condenser 27 is used for keeping the hot pot 11 warm.

Preferably, the evaporator 29 is an in-line evaporator coiled around the cold pot 21.

With the above structure, the line-type evaporator 29 can increase the cooling area between the evaporator and the cooling kettle 21, thereby improving the cooling efficiency.

In one embodiment, the evaporator 29 is disposed on the cold-conducting sleeve 22, the cold-conducting sleeve 22 being formed as a sandwich sleeve, the inner sandwich wall 22a of which encloses the sleeve cavity of the cold-conducting sleeve 22, the evaporator 29 being mounted in the sleeve sandwich cavity 22c of the sandwich sleeve. At this time, the evaporator 29 can refrigerate the cooling kettle inner container 21 by the cold conducting function of the inner interlayer wall 22a of the interlayer sleeve.

In the above description, in order to improve the cooling efficiency, the cooling medium may be filled between the inner wall of the cooling sleeve 22 and the outer wall of the cooling kettle liner 21 c. More specifically, the cold conducting medium is arranged between the inner interlayer wall 22a of the interlayer sleeve and the inner liner peripheral wall of the cold pot inner liner 21 c. In addition, in the above, a heat insulating layer 23 may be provided between the outer wall of the cooling guide sleeve 22 and the inner wall of the insertion groove. More specifically, the thermal insulation layer 23 is arranged between the outer interlayer wall 22b of the interlayer sleeve and the inner wall of the cold pot insertion groove 24.

Returning to the above embodiment, the evaporator 29 and the inner sandwich wall 22a may be disposed at a distance. At this time, the jacket cavity 22c may be filled with a cooling medium to enhance the cooling effect between the evaporator 29 and the inner jacket wall 22 a.

Alternatively, as shown in fig. 12, the evaporator 29 may be fixed on the inner sandwich wall 22a by welding or bonding, but in this structure, when hot water is introduced into the inner container 21c of the cold kettle to achieve rapid ice shedding, the heat of the hot water is rapidly conducted to the evaporator 29 through the inner sandwich wall 22a, which may cause high-pressure damage to the evaporator 29, and thus, the working performance and the service life thereof are affected.

Further, as shown in fig. 13, the evaporator 29 attached by welding, bonding, or the like may be provided with a flat tube 29c as a line, and the flat side of the flat tube 29c and the inner cladding wall 22a may be bonded to each other. The flat side of the flat pressure tube 29c has a larger cooling area than the circular tube, and the cooling efficiency of the evaporator 29 can be further improved.

In another embodiment, the evaporator 29 can be provided as a cast structure integrally with the cold-conducting sleeve 22, and the lines of the evaporator 29 are at least partially embedded in the cold-conducting sleeve 22. The pipeline of the evaporator 29 is a copper pipe, and the cold guide sleeve 22 is an aluminum casting, so that the cold guide sleeve has good cold guide performance.

In another embodiment, the evaporator 29 may be formed by integral casting with the kettle liner 21c, i.e. the cold guiding process of the cold guiding sleeve 22 can be omitted, so that the refrigerating capacity of the evaporator 29 is directly transmitted to the kettle liner 21 c. Preferably, the inner container 21c of the cooling kettle is an aluminum casting with good cooling performance, and the pipeline of the evaporator 29 is a copper pipe.

To increase the cooling area between the evaporator 29 and the cooling pot 21, the evaporator 29 may preferably be provided in a single spiral shape or a double spiral shape. And the number of turns of the evaporator 29 may be set to be not more than 100 turns, based on the actual size of the cold pot 21. In addition, since the desired temperature of the cooling kettle 21 is different when cooling water, making ice, or cooling hot water, the refrigerant flow rate in the pipeline of the evaporator 29 should be adapted to different cooling requirements. For this reason, the tube diameter of the evaporator 29 may be set within a range of 1mm to 50 mm.

Further, the line of the evaporator 29 may be wound around the outer circumference of the cooling pot 21, or may be wound around the bottom of the cooling pot 21, or may be wound around both the outer circumference and the bottom of the cooling pot 21. Obviously, the evaporator structure wound around the outer periphery and the bottom of the cooling kettle 21 has a larger cooling area, which is more beneficial to increase the cooling speed of the cooling kettle 21.

It should be noted that the evaporator 29 provided around the cooling pot 21 may be replaced by a separately provided refrigeration line, or the evaporator 29 may be refrigerated in combination with the separately provided refrigeration line. Although the refrigerant flows through the lumen of the refrigeration line, the power source for driving the refrigerant to flow is not limited to the compressor, and the refrigerant may be driven to flow by a power pump or the like. In other words, the coiled evaporator 29 is one of the possible structures of the refrigeration lines, and the cooling kettle 21 of the present invention can be used for cooling by other different types of refrigeration lines.

Preferably, as shown in fig. 14, the throttle line downstream section 28c of the throttle element 28 is disposed so as to be wound around the evaporator outlet line 29b of the evaporator 29.

Because the temperature of the peripheral wall of the evaporator outlet pipeline 29b is low, after the downstream section 28c of the throttling pipeline and the evaporator outlet pipeline 29b are wound, the temperature of the refrigerant in the throttling element 28 can be further reduced, and the refrigeration efficiency can be improved.

In one embodiment, the throttle line downstream section 28c may be wound around the evaporator outlet line 29 b. At this time, the diameter of the downstream section 28c of the choke line should be equal to the diameter of the outlet line 29b of the evaporator, or the diameter of the downstream section 28c of the choke line should be smaller than the diameter of the outlet line 29b of the evaporator, so as to ensure that the downstream section 28c of the choke line is wound around the outlet line 29b of the evaporator. Thus, the throttling element 28 at this point may be an expansion valve or a capillary throttle.

In another embodiment, the evaporator outlet line 29b may be wound around the throttle line downstream section 28 c. At this time, it is difficult to wind the evaporator outlet line 29b around the capillary throttle tube, and therefore the throttle element 28 in the present embodiment is an expansion valve.

Specifically, the choke line of the choke element 28 includes a choke line upstream section 28a, a transition connection section 28b, and the above-described choke line downstream section 28c, which are connected in series. Wherein the throttle line upstream section 28a is connected to the condenser 27 and the transition connection section 28b is at least partially helical. Through forming transition connection section 28b at least part into the heliciform, can avoid its condition of seriously buckling to can reduce its volume so that fix, can promote the throttle effect to the refrigerant simultaneously.

In order to save space required by the throttling element 28, in some embodiments, the transition connection section 28b may be configured to bend adaptively along the peripheral wall of the lower cartridge bay cover 25, i.e., to substantially conform to the shape of the peripheral wall of the lower cartridge bay cover 25.

Furthermore, a part of the line segment of the throttle line downstream segment 28c may be formed as a kink tip 28d provided downward for draining the condensed water accumulated on the outer circumferential wall of the evaporator.

Further, the evaporator 29 includes an evaporator inlet line 29a and the evaporator outlet line 29b described above. Based on the water guiding function of the above-described bend tip portion 28d, it is preferable to dispose the evaporator outlet line 29b higher than the evaporator inlet line 29a, and dispose the evaporator inlet line 29a to protrude from the bottom of the evaporator 29. With this structure, the condensed water accumulated at a high level in the evaporator 29 can spontaneously flow down along the line of the throttling element 28 by gravity, and is finally accumulated in the bent tip portion 28 d.

In order to receive the condensation water dripping from the bent tip 28d, a compressor sump 211 may be arranged below the bent tip 28d, the compressor sump 211 preferably being arranged in the base interior of the base 3.

Preferably, the compressor 26 is installed at a position closer to the cooling kettle 21 than the heating kettle 11, so that the area division between the heating part 1 and the cooling part 2 is more definite, and the components in the inner cavity of the base are more uniformly and reasonably arranged.

Preferably, referring to fig. 15 and 16, the intake duct of the compressor 26 may be at least partially provided as a transparent pipe section 26a, and a base observation window 36 for observing the amount of oil accumulated in the transparent pipe section 26a is provided on the base 3.

Through setting up this transparent pipeline section 26a and base observation window 36, the user can monitor the long-pending oily condition in the intake pipe of compressor 26 at any time, and when observing that the long-pending oily volume in transparent pipeline section 26a is more and long-pending oil can not flow back to the upper reaches voluntarily, the user can take oil return treatment measures immediately to effectively avoid long-pending oil to get into in the compressor 26 and cause the liquid hammer, guarantee the reliability and the stability of compressor 26.

When the integrated cooling and heating apparatus 100 of the present invention is used, a user usually looks down the apparatus. Therefore, in order to further facilitate the observation by the user, it is preferable to provide the base observation window 36 on the top wall of the base 3.

In addition, to avoid viewing blind spots as much as possible, it should be ensured that all of the transparent segments 26a are visible. For example, the base viewing window 36 may be provided as a rectangular window and the transparent tube segment 26a may be disposed along the length of the rectangular window. Wherein the length of the transparent tube section 26a is no greater than the length of the rectangular window, ensuring that a user can view the complete transparent tube section 26a through the base viewing window 36.

Further, the transparent pipe section 26a may include a plurality of connected pipe sections in sequence, and a joint of the pipe sections is provided with a transparent sealing ring, which can ensure that the joint of the pipe sections of the transparent pipe section 26a is in a visible state, thereby effectively avoiding observation blind spots.

Referring to fig. 17, the integrated cooling and heating apparatus 100 may include an illumination lamp 6 for illuminating the transparent pipe section 26 a. Under the illumination of the illuminating lamp, the oil accumulation in the transparent pipe section 26a is easier to observe, thereby reducing the observation error of a user. More preferably, the illumination lamp 6 is configured to be turned on or off under the control of a user, thereby effectively saving power consumption.

In one embodiment, transparent tube section 26a is horizontally oriented and the height of the upstream intake tube section upstream of transparent tube section 26a is lower than the height of transparent tube section 26 a. With this configuration, the oil accumulated in the transparent pipe section 26a is difficult to spontaneously flow back into the upstream intake pipe section due to the balance of the forces. Accordingly, a compressor oil return device for diverting oil accumulation in transparent tube section 26a upstream may be provided in a compressor refrigeration system and configured to initiate operation when the compressor oil return key is activated. In other words, when the user observes that the oil accumulation in the transparent pipe section 26a is large, the compressor oil return key can be actively triggered, and the compressor oil return device is driven to perform the oil return action.

In another embodiment, the upstream end of transparent tube segment 26a is disposed at a downward slope relative to the downstream end. At this time, the oil accumulated in the transparent pipe section 26a can spontaneously flow back to the upstream end under its own weight. However, when the viscosity of the accumulated oil is high or the oil return speed needs to be increased, the oil must be actively returned by the compressor oil return device.

Specifically, the compressor refrigeration system is further provided with a refrigerant supplement pipe communicated with an air inlet pipe of the compressor 26, the refrigerant supplement pipe may be an internal refrigerant supplement pipe arranged in the base inner cavity, and at this time, the base inner cavity needs to be provided with a built-in refrigerant tank. Alternatively, the refrigerant-replenishing pipe may be an external refrigerant-replenishing pipe extending outside the base, and at this time, the refrigerant is replenished from the outside.

Preferably, referring to fig. 18, the compressor refrigeration system further includes a defrosting fan 210, and the defrosting fan 210 is configured to blow air toward the outer peripheral wall of the compressor 26 to accelerate frost melting, ensure the working efficiency of the compressor 26, and improve the stability and reliability thereof. For example, the defrosting fan 210 may be provided between the condenser 27 and the compressor 26 to melt a frost layer on the outer peripheral wall of the compressor 26 by discharging heat of the condenser 27 toward the compressor 26.

In addition, a protective coating may be provided on the outer peripheral wall of the compressor 26, the protective coating including an inner-to-outer primer protective layer, a thermal insulating coating, and a hydrophobic coating. In other words, by providing the protective coating, the strength, heat insulating property, and water-repellent property of the outer peripheral wall of the compressor 26 are effectively improved, thereby preventing frost formation.

As can be seen from the foregoing and with reference to fig. 19, the compressor refrigeration system includes a compressor sump box 211 located below the bottom of the compressor 26. When the frost layer on the outer peripheral wall of the compressor 26 melts, the liquid droplets can flow down the outer peripheral wall into the compressor residue box 211.

Further, the compressor residual water tank 211 is preferably provided in a detachable structure. When the residual water in the compressor residual water box 211 is more, the compressor residual water box 211 can be directly detached and the residual water in the compressor residual water box 211 can be poured out. Alternatively, a PTC heating sheet may be disposed at the bottom of the compressor residual water box 211, and the residual water in the compressor residual water box 211 may be heated and dried by the PTC heating sheet. Alternatively, a drying fan 212 may be provided at the bottom of the compressor residual water box 211 or in the base inner cavity, and the residual water in the compressor residual water box 211 may be dried by the hot air blown by the drying fan 212.

In addition, the compressor 26 generates large vibration and noise during operation, and the compressor noise is a main noise source of the integrated cooling and heating device 100 of the present invention, so that the compressor 26 needs to be subjected to vibration and noise reduction.

Preferably, referring to fig. 20 and 21, a vibration-proof base 213 may be provided at the bottom of the compressor 26. The shock absorbing base 213 may include a shock absorbing bracket 213a, a shock absorbing spring 213b disposed on the shock absorbing bracket 213a, and a shock absorbing silicone ring 213c disposed on a peripheral portion of the shock absorbing bracket 213 a. The upper end and the lower end of the cushioning spring 213b are respectively connected to the bottom of the compressor 26 and the top wall of the shockproof support 213a, and the shockproof silica gel ring 213c wraps the peripheral wall of the bottom of the compressor 26. Therefore, the vibration of the compressor 26 can be effectively buffered by arranging the vibration damping base 213 connected with the compressor 26 in a vibration damping manner at the bottom of the compressor 26, so that the working noise of the compressor can be reduced.

In addition, referring to fig. 22, the outer wall of the compressor 26 may be wrapped with a shock absorption protection layer 214, and since the entire compressor 26 is located in the shock absorption protection layer 214, collision with other components and vibration absorption can be avoided. Preferably, a foam-filled protective layer or a rubber particle-filled protective layer can be used as the cushioning protective layer 214, which has the characteristics of low cost and good cushioning performance.

Preferably, the heat of the condenser 27 can be used to keep the hot pot 11 warm.

The heat generated by the condenser 27 is skillfully utilized to keep the heat of the hot pot 11 warm, and a heat insulation structure needing additional design can be omitted, so that the cold and hot integrated device 100 has an auxiliary heat insulation function for the hot pot 11 on the premise of saving the space in the machine and the production cost.

Further, the condenser 27 may be disposed right under the hot pot 11, so that the heat emitted from the condenser 27 can be substantially concentrated on the bottom wall of the hot pot 11 for heat preservation, thereby improving the utilization of the heat.

To ensure that the heat generated by the condenser 27 can be directed to the outer wall of the kettle 11, an inner heat dissipation fan 4 can be preferably disposed in the inner cavity of the base, and the inner heat dissipation fan 4 can discharge the heat of the condenser 27 towards the kettle 11. More preferably, the condenser 27 and the inner heat dissipating fan 4 are stacked in the inner cavity of the base from top to bottom and located below the hot pot 11, and for convenient procurement and assembly, the condenser 27 is preferably provided integrally with the fan frame 41 of the inner heat dissipating fan 4. In addition, the bottom wall of the base 3 is provided with an axial heat radiation air inlet 34, the groove peripheral wall of the hot pot insertion groove 12 is provided with a radial heat radiation air outlet 35, and the inner heat radiation fan 4 and the heat radiation air inlet 34 are arranged at intervals along the axial direction. It can be seen that the condenser 27 is disposed in the air duct formed by the heat dissipation air inlet 34 and the heat dissipation air outlet 35, which can not only realize the heat preservation of the hot pot 11, but also does not affect the normal heat dissipation of the inner cavity of the base.

Alternatively, referring to fig. 23 to 25, the integrated cooling and heating apparatus 100 may include an outer heat radiating fan 5 disposed on an outer sidewall of the base 3. At this time, the condenser 27 is preferably configured to be strip-shaped and horizontally arranged along the outer side wall of the base 3, and the plurality of outer heat dissipation fans 5 are sequentially arranged at intervals along the horizontal arrangement direction of the condenser 27.

Further, the heating part 1 includes a pot heating element 13 for heating the pot 11, and the electric control board 10 is configured to control the pot heating element 13 to operate with reduced power or to operate intermittently when the temperature of the pot 11 is lower than the keeping warm temperature. This is because when the kettle heating element 13 is powered down or intermittently operated, the heating efficiency of the kettle 11 is reduced, but the hot water in the kettle 11 can still be controlled within a certain temperature range. Preferably, the holding temperature may be set to not less than 40 ℃.

On the other hand, the integrated cooling and heating device 100 may include a PTC heating sheet for keeping the temperature of the hot pot 11, and the PTC heating sheet may be provided on the peripheral wall or the bottom wall of the hot pot 11 for keeping the temperature of the hot pot 11 with low power heating.

When both the heating unit 1 and the cooling unit 2 stop operating, the heat of the kettle 11 cannot be preserved by the heat dissipation unit of the cooling system. Therefore, the heat dissipation air inlet 34 and the heat dissipation air outlet 35 can be closed when the heating portion 1 stops heating, so that the residual heat in the inner cavity of the base is locked, and the loss of heat is reduced. When any one of the heating unit 1 and the cooling unit 2 is restarted, the heat dissipation air inlet 34 and the heat dissipation air outlet 35 need to be controlled to be opened again, so as to avoid affecting normal heat dissipation.

In addition, in order to further avoid the influence on the normal heat dissipation of the cold and hot integrated device 100, a heat dissipation temperature sensor for sensing the heat dissipation temperature of the heat dissipation air outlet 35 may be disposed in the inner cavity of the base. When the heat dissipation temperature sensed by the heat dissipation temperature sensor is higher than the safety temperature threshold, the cold and hot integrated device 100 can be controlled to stop working immediately, so that the machine is not damaged due to overheating, and the reliability and the safety are improved.

Preferably, the base 3 may be provided as a metal base, and base fins, which can be operated alone or in cooperation with a heat radiating fan, are provided on an inner wall of the metal base.

Referring to fig. 26 and 27, the integrated cooling and heating device 100 of the present invention further includes a cold pot heating structure for heating and deicing the cold pot 21. Through setting up this cold pot heating structure, cold pot 21 can realize taking off ice fast after accomplishing the ice-making, satisfies the requirement of user to quick ice-making.

In one embodiment, the cold pot heating structure comprises a heat conducting water pipe 7 and a heat conducting water pump 8 for powering water flow in a pipeline of the heat conducting water pipe 7, one end of the heat conducting water pipe 7 is communicated with a hot pot inner cavity of the hot pot 11, and the other end can be wound around the cold pot 21. When the hot water in the hot pot 11 flows to the heat conduction water pipe 7, the cold pot 21 can rapidly absorb heat and de-ice to form ice blocks with proper size for users to take.

It should be noted that the hot water outlet pipe may serve as the heat conducting water pipe 7 in this embodiment, and when the hot water outlet pipe is wound around the cold water kettle 21, the hot water outlet pipe can assist in deicing and can also quickly cool the hot water in the pipeline for the user to drink.

In another embodiment, two ends of the heat conducting water pipe 7 can be respectively communicated with the hot pot inner cavity of the hot pot 11 and the cold pot inner cavity of the cold pot 21, that is, hot water is directly guided into the cold pot inner cavity to realize ice removal. Preferably, a flow control valve is arranged in the pipeline of the heat conducting water pipe 7 under the structure, and the flow control valve is used for controlling the amount of hot water drained into the inner cavity of the cold pot, so that the ice blocks can be prevented from being melted in a large area due to excessive ice shedding.

In another embodiment, the cold pot heating structure comprises a heat conducting fan 9 disposed in the base interior cavity, the heat conducting fan 9 being adapted to discharge heat from the condenser 27 towards the cold pot 21. The heat conducting fan 9 is preferably disposed between the condenser 27 and the cooling pot 21 so as to guide heat emitted from the condenser 27 to one side of the cooling pot 21.

In the present embodiment, when the auxiliary cooling kettle 21 is required to be used for ice shedding, the refrigeration system is already in the stop state, so the heat emitted by the condenser is only the heat dissipation margin. Therefore, in order to ensure that the base cavity has enough heat dissipation margin for deicing, the heat dissipation air inlet 34 and the heat dissipation air outlet 35 can be set to be closed when the heat conduction fan 9 works, and can be opened again after deicing is completed, so as to avoid affecting normal heat dissipation.

In another embodiment, the cold pot heating structure comprises a PTC heating plate for heating the cold pot 21. The PTC heating sheet can be preferably arranged on the outer wall of the cold pot 21, and when the PTC heating sheet is used for low-power heating, the deicing effect is good, and the stability is high.

In another embodiment, the function of the refrigerating part and the radiating part of the refrigerating system can be switched to realize quick ice-shedding. Specifically, for the integrated cooling and heating device 100 provided with a compressor refrigeration system, a refrigerant reversing valve is provided in the compressor refrigeration system. At this time, the evaporator 29 for refrigerating the kettle 21 can be switched to heat and deice the kettle 21 by the refrigerant switching valve, and when the kettle 21 needs to be refrigerated, the evaporator can be switched to refrigerate the kettle 21 by the refrigerant switching valve again. In other words, by providing the refrigerant reversing valve, the functions of the evaporator 29 and the condenser 27 in the compressor refrigeration system can be switched with each other.
