Furthermore, the different embodiments or examples described in this specification and the features of the different embodiments or examples may be combined and combined by those skilled in the art without contradiction.

As shown in fig. 1 to 14, the present embodiment provides a refrigeration apparatus 100, the refrigeration apparatus 100 including an ice making compartment 102, and an ice making case 104 and an ice bank 106 disposed inside the ice making compartment 102, the ice making case 104 being located above the ice bank 106 in a vertical direction. With this arrangement, when the ice making housing 104 completes making ice, it can be turned down to effect ice removal, and ice cubes removed from the ice making housing 104 can drop into the ice bank 106. In the process of ice removal, the ice-making housing 104 may be heated by a heating wire provided at the bottom of the ice-making housing 104 to complete the ice removal.

The ice making housing 104 includes a housing 126, and a plurality of ice grooves 130 are provided in the housing 126, and a certain amount of fresh water can be added to the ice grooves 130 during actual ice making, and ice making can be achieved by cooling the ice making housing 104.

A base 128 is provided at the bottom of the ice tank 130, and a flow channel 132 is formed in the ice making case 104, and the flow channel 132 is used for introducing a refrigerant such as a refrigerant or a cold storage agent to cool and refrigerate the ice tank 130. Taking the coolant as an example, in order to achieve the purpose of introducing the coolant into the flow channel 132, a fluid inlet 140 and a fluid outlet 138 are provided in the flow channel 132, the fluid inlet 140 being used for introducing the coolant into the flow channel 132, and the fluid outlet 138 being used for discharging the coolant in the flow channel 132. It is understood that in the embodiment of the present application, cooling and refrigerating of the ice tank 130 may be achieved by introducing a cold storage agent into the bottom of the ice tank 130. To prevent leakage of the coolant, a seal 166 is also provided between the ice trough 130 and the base 128. For example, the seal 166 may be a gasket, or the like.

Meanwhile, in order to ensure that the coolant entering the circulation tank 132 can perform sufficient heat exchange with the bottom of the ice tank 130, in the embodiment of the present application, the fluid outlet 138 of the circulation tank 132 is located at the highest point of the circulation tank 132, the fluid inlet 140 of the circulation tank 132 is located at the lowest point of the circulation tank 132, and the top wall of the circulation tank 132 is gradually inclined upwards from the fluid inlet 140 to the direction of the fluid outlet 138.

By this arrangement, the coolant in the circulation tank 132 needs to completely fill the circulation tank 132 before it can flow out of the circulation tank 132 from the fluid outlet 138 located at the highest point of the circulation tank 132. Thereby ensuring that the coolant in the circulation tank 132 can sufficiently exchange heat with the ice tank 130. By arranging the top wall of the circulation tank 132 to be gradually inclined upwards from the fluid inlet 140 to the direction of the fluid outlet 138, it is ensured that if the circulation tank 132 is filled with the gas, the gas can be extruded out of the circulation tank 132 from the fluid outlet 138 positioned at the highest circulation point along with the gradual filling of the coolant, thereby avoiding insufficient contact between the coolant and the ice tank 130 and ensuring the heat exchange effect of the coolant and the ice tank 130.

It is understood that the flow channel 132 formed in the ice making housing 104 is the heat exchange tube segment 110 in the ice making line 108, and the heat exchange tube segment 110 is configured to exchange heat with the ice making housing 104.

In other embodiments, the heat exchange tube segment 110 in the ice making and ice making tube 108 may also be formed by conforming the ice making tube 108 to the form of the ice making housing 104. In such an embodiment, the ice making pipe 108 may be fitted to the bottom or side of the ice making housing 104 as long as the cooling capacity in the ice making pipe 108 can be transferred to the ice bank 130 in the ice making housing 104.

As described above, in the embodiment of the present application, since cooling and refrigerating of the ice tank 130 are achieved by using the way of introducing the coolant, in order to ensure that the coolant can fully contact the ice tank 130, the ice tank 130 and the circulation tank 132 provided in the embodiment of the present application may be at least provided in the following ways.

Setting mode one:

in this arrangement, the bottom of the ice groove 130 may be provided as a curved surface, and accordingly, the flow-through groove 132 corresponds to the heat exchange wall 134 of the ice groove 130 as a curved surface curved toward the bottom of the flow-through groove 132. As shown in fig. 12 and 14, the cross-sectional shape of the flow channel 132 may be generally concave. Of course, in other embodiments, the heat exchange wall 134 of the flow channel 132 corresponding to the ice channel 130 may be formed in other shapes, for example, the heat exchange wall 134 of the flow channel 132 corresponding to the ice channel 130 may be formed in a wavy shape, a zigzag shape, or the like, so long as the contact area between the bottom of the ice channel 130 and the flow channel 132 can be increased.

Setting mode II:

in this arrangement, as shown in fig. 12, a number of first heat exchanging structures 136 may be provided in the flow channel 132, where the first heat exchanging structures 136 may be fins, heat exchanging plates, etc. Taking the first heat exchanging structure 136 as a fin as an example, the fin may be disposed at the bottom of the ice tank 130 and extend into the circulation tank 132, when the coolant flows through the circulation tank 132, the coolant can exchange heat with the fin sufficiently, and meanwhile, the fin can also form turbulence in the coolant, and when the heat exchange between the fin and the coolant is completed, the fin transfers the cooling capacity to the ice tank 130. Of course, the fins may be provided on the base 128, and this may be achieved as well. Or the fins may be provided at the bottom of the ice bank 130 and on the base 128 at the same time. In this embodiment, the fins, the ice grooves 130 and the circulation grooves 132 may be integrally formed, or may be detachably connected.

The manner of arranging the fins will be briefly described below, and the fins may be arranged so as to extend in the longitudinal direction of the flow channel 132 and be arranged at intervals in the width direction of the flow channel 132. The space between two adjacent fins should not be too small, so that the fins can be prevented from generating resistance to the flow of the coolant. The fins may be provided so as to be inclined along the longitudinal direction of the flow grooves 132, and the inclined direction of the fins may be provided along the flow direction of the coolant. That is, the fins are gradually inclined from the inflow direction of the coolant to the outflow direction of the coolant.

Setting mode III:

in this arrangement, the first arrangement and the second arrangement may be combined, that is, the heat exchanging wall surface 134 of the circulation groove 132 corresponding to the ice groove 130 is arranged in a curved form toward the bottom of the circulation groove 132, and at the same time, fins are provided on at least one of the bottom of the ice groove 130 and the base 128 to improve the heat exchanging efficiency of the coolant and the ice groove 130.

And the setting mode is four:

in this arrangement, a plurality of spacers may be disposed along the length direction of the circulation groove 132 at intervals on two opposite sidewalls of the circulation groove 132 in the left-right direction as shown in fig. 14, and two adjacent spacers are disposed in a staggered manner, so that the coolant can flow in a bent path in the circulation groove 132 after entering the circulation groove 132, thus prolonging the flowing time of the coolant in the circulation groove 132, and further prolonging the contact time of the coolant with the ice groove 130, so that the coolant and the ice groove 130 can perform sufficient heat exchange.

Of course, the heat exchange efficiency of the ice tank 130 and the coolant can be improved by other ways, for example, the circulation tank 132 can be directly set to be in a bent shape, and the flowing time of the coolant in the circulation tank 132 can be prolonged by setting the circulation tank 132 to be in a bent shape, so that the contact time of the coolant and the ice tank 130 can be correspondingly prolonged, and further the overall cooling and refrigerating of the ice tank 130 can be realized.

In order to provide a driving force for the flow of the coolant, according to one embodiment of the present application, a driving member 116 is also provided on the ice making line 108, where the driving member 116 may be a pump.

The ice-making circuit may be in direct communication with the refrigeration circuit 114 when the flow-through tank 132 is vented with refrigerant. The ice-making circuit may be connected in parallel with the evaporator circuit of the refrigerated compartment, or directly in series with the refrigeration circuit 114 of the refrigeration unit 100.

In the embodiment of the present application, the cooling and cooling modes of the ice tank 130 are implemented by introducing a refrigerant such as a refrigerant and a cold storage agent into the flow channel 132.

In the present embodiment, the cooling of the coolant may be achieved by passing the ice making line 108 into the heat exchanger 118.

Cooling of the ice making circuit 108 can be achieved by passing the ice making circuit 108 into the heat exchanger 118, and when the temperature of the ice making circuit 108 is reduced, cooling energy can be transferred to the coolant in the ice making circuit 108. Thus, a first liquid inlet pipe for introducing the coolant and a first liquid outlet pipe for discharging the coolant are provided in the heat exchanger 118, and the first liquid inlet pipe and the first liquid outlet pipe constitute a coolant pipe 124 for circulating the coolant. The cooling of the cold storage agent pipe 124 may be performed by using the refrigerating evaporator 120 in the refrigerating compartment, the refrigerating evaporator 120 in the freezing compartment, or the refrigerating evaporator 120 for cooling the other refrigerating compartments 142.

In order to improve the heat exchange performance of the heat exchanger 118, a second heat exchange structure 170 is further disposed on the heat exchanger 118, and the second heat exchange structure 170 may be a structure formed on the surface of the heat exchanger 118, such as fins or protrusions, which can increase the surface area of the heat exchanger 118.

In the embodiment of the present application, the heat exchange manner of the heat exchanger 118 may at least take the following several forms:

heat exchange mode one:

in this heat exchange mode, as shown in fig. 1, the heat exchanger 118 may be cooled by the refrigeration evaporator 120 in the refrigeration compartment 142. The refrigeration evaporator 120 is mounted in a first mounting cavity 144 of the refrigeration compartment 142. Accordingly, since it is necessary to guide the cooling capacity of the refrigerating evaporator 120 in the refrigerating compartment 142 to the heat exchanger 118, a first air inlet duct 146 and a first return duct 148 are provided between the heat exchanger 118 and the refrigerating evaporator 120 in the refrigerating compartment 142, a first air door 152 is provided in the first air inlet duct 146, a second air door 154 is provided in the first return duct 148, and a first fan 174 is also provided in the first chamber in which the refrigerating evaporator 120 is installed. When the heat exchanger 118 needs to be cooled, the first fan 174 may be turned on, and the first air door 152 and the second air door 154 may be opened at the same time, so that the cooling capacity in the refrigeration evaporator 120 is blown to the heat exchanger 118 through the first air inlet pipe 146, and after the cooling air is blown through the heat exchanger 118, the heat of the heat exchanger 118 is taken away and flows back to the refrigeration evaporator 120 through the first air return pipe 148, so as to form an air cooling cycle for cooling the heat exchanger 118.

When the coolant flows into the heat exchanger 118 through the first liquid inlet pipe, the coolant can be cooled by exchanging heat with the heat exchanger 118, and when the coolant flows out of the heat exchanger 118 through the first liquid inlet pipe, the coolant enters the circulation groove 132, so that the coolant can be cooled in the ice groove 130.

It should be noted that, the refrigeration evaporator 120 in the refrigeration compartment 142 mentioned herein may use a refrigeration compartment, or the refrigeration evaporator 120 in the refrigeration evaporator 120 that cools the other refrigeration compartments 142 to cool the heat exchanger 118.

And a second heat exchange mode:

in this heat exchange manner, a second fan 150 may be further provided in the ice making compartment 102, which is different from the heat exchange manner. When the heat exchanger 118 needs to be cooled, the second fan 150 may be turned on to guide the cold energy in the refrigeration evaporator 120 in the refrigeration compartment 142 to the heat exchanger 118 through the first air inlet pipe 146, and after the cold air blows through the heat exchanger 118, the heat of the heat exchanger 118 is taken away and flows back to the refrigeration evaporator 120 through the first air return pipe 148, so as to form an air cooling cycle for cooling the heat exchanger 118. This allows the refrigeration compartment 142 and the heat exchanger 118 to be cooled separately by adding the second fan 150. That is, when the refrigeration compartment 142 requires refrigeration, the first blower 174 may be turned on alone; when heat exchange is desired in heat exchanger 118, first fan 174 and second fan 150 may be turned on simultaneously.

It should be noted that, the refrigeration evaporator 120 in the refrigeration compartment 142 mentioned herein may use a refrigeration compartment, or the refrigeration evaporator 120 in at least one refrigeration compartment 142 of the refrigeration evaporators 120 that cools the other refrigeration compartments 142 to cool the heat exchanger 118.

And a heat exchange mode III:

in this heat exchange mode, the heat exchanger 118 may be cooled by the refrigeration circuit 114 of the refrigeration unit 100. Thus, the heat exchanger 118 is provided with a second liquid inlet pipe for introducing the refrigerant and a second liquid outlet pipe for discharging the refrigerant, in addition to the first liquid inlet pipe and the first liquid outlet pipe for circulating the coolant. When the refrigerant in the refrigeration equipment flows into the heat exchanger 118 through the second liquid inlet pipe, the temperature of the heat exchanger 118 can be reduced, the heat of the heat exchanger 118 is taken away, and the refrigerant flows out of the heat exchanger 118 through the second liquid outlet pipe and then enters the refrigeration loop 114 of the refrigeration equipment 100, so that the liquid cooling circulation of the heat exchanger 118 is formed.

In the above three heat exchanging modes, the heat exchanger 118 may be installed in the ice making chamber 102, and accordingly, a second installation cavity may be provided in the ice making chamber 102 for installing the heat exchanger 118, for example, the second installation cavity may be provided at an outer side of the ice making chamber 102, so that the heat exchanger 118 can be prevented from occupying a space inside the ice making chamber 102. The heat exchanger 118 may also be installed in other refrigerated compartments 142. It should be understood that the second installation cavity mentioned herein is an installation space 178 of the heat exchanger 118, and the working space 180 of the ice making chamber 102 is an internal space when ice is actually made.

And a heat exchange mode is four:

in this heat exchange mode, an ice making evaporator 122 may be connected in parallel with the refrigeration circuit 114, and heat may be exchanged to the heat exchanger 118 through the ice making evaporator 122. Or a control valve may be disposed between the circulation loop of the ice making evaporator 122 and the refrigeration loop 114 of the refrigeration appliance 100, and when there is an ice making demand, the control valve is opened, so that the combined control of the refrigeration loop 114 of the refrigeration appliance 100 and the circulation loop of the ice making evaporator 122 can be realized.

The ice making evaporator 122 and the heat exchanger 118 can be connected through a pipeline, or the cold energy on the ice making evaporator 122 is blown to the heat exchanger 118 through an air cooling mode. For example, in this heat exchange manner, the heat exchanger 118 may be connected to the ice making evaporator 122 in the form of a micro channel, and in this case, the heat exchanger 118 may be disposed in a second installation cavity on the ice making chamber 102. Meanwhile, the heat exchanger 118 and the ice making evaporator 122 are connected through the micro-channel, so that the structure of the heat exchanger 118 can be reduced, the miniaturization of the heat exchanger 118 is realized, and the heat loss is small.

Of course, in other embodiments, the several cooling modes described above may be combined with one another to further increase the cooling rate for the heat exchanger 118.

According to one embodiment of the present application, when de-icing is required at the end of ice making, in order to ensure that the coolant in the circulation tank 132 flows back as soon as possible, the ice making housing 104 may be provided in an inclined form, or only the heat exchange tube section 110 in the ice making circuit may be provided in an inclined form. It will be appreciated that to achieve the above, the fluid outlet 138 of the heat exchange tube segment 110 may be provided in the form of a lowest point of the heat exchange tube segment 110.

As shown in fig. 3, a heat exchanger 118 for exchanging heat with the coolant, a driving member 116 for driving the coolant to flow, and a coolant tank 176 for storing the coolant may be provided near the rear in the refrigeration apparatus 100. Thus, the direction of inclination of the ice making housing 104 may be gradually inclined downward from the fluid inlet 140 of the heat exchange tube segment 110 toward the fluid outlet 138 of the heat exchange tube segment 110. That is, referring to fig. 3, when the heat exchanger 118, the driving part 116, and the cold storage tank 176 are disposed at positions near the rear of the refrigeration apparatus 100, the left side of the ice making housing 104 may be disposed relatively high and the right side of the ice making housing 104 may be disposed relatively low. Accordingly, the left side of the heat exchange tube segment 110 is disposed relatively higher and the right side of the heat exchange tube segment 110 is disposed relatively lower. Thus, when ice making is completed, the coolant in the circulation tank 132 can quickly flow back to the coolant tank 176 by gravity. Thus, the problem of slow heating rate of the heating wire due to the cold storage agent remained in the circulation groove 132 is avoided, and the ice removing efficiency is improved.

In other embodiments, the heat exchange tube segment 110 may also be configured in a stepped fashion, i.e., the heat exchange tube segment 110 may be configured to decrease in a stepped fashion from the direction of the fluid inlet 140 toward the direction of the fluid outlet 138.

In the embodiment of the present application, in order to further increase the rate of backflow of the cold storage agent, the volume of the storage space of the cold storage tank 176 is greater than the volume of the entire cold storage agent in the ice making line 108, that is, assuming that the sum of the volumes of the cold storage agents flowing in the ice making line 108 is 4 liters, the volume of the storage space of the cold storage tank 176 is 5 liters. By this arrangement, when ice making is completed, the coolant in the ice making line 108 can quickly flow back into the coolant tank 176. In this way, when the heating wire works, no cold storage agent remains in the circulation groove 132, so that the heating efficiency of the heating wire to the ice groove 130 can be ensured, and the purpose of quick ice removal can be realized.

In the embodiment of the present application, the cooling mode of the ice bank 106 is implemented in an air-cooled mode, and accordingly, the refrigeration apparatus 100 includes the ice storage air duct 112. As described above, since the ice making is realized by the ice making duct 108 of the ice making case 104 and the ice storing is realized by the ice storing duct 112 of the ice storing case 106, when the ice making case 104 is in the heating and de-icing state, the ice storing case 106 can realize the low temperature ice storing solely by the form of the ice storing duct 112, and thus the temperature of the ice storing case 106 is not affected by the heating and de-icing, and further melting of ice cubes stored in the ice storing case 106 can be avoided, and the ice storing effect of the ice storing case 106 is ensured.

In the embodiment of the present application, at least the following different cold sources may be used as the cold source of the ice storage wind path 112:

the implementation mode is as follows:

in this implementation, as shown in fig. 1, the ice bank 106 may be cooled by the refrigerating evaporator 120 in the refrigerating compartment 142 as a cold source of the ice storage wind path 112, that is, the cooling capacity of the refrigerating evaporator 120 in the refrigerating compartment 142 may be used. Accordingly, since it is necessary to guide the cooling capacity of the refrigerating evaporator 120 in the refrigerating compartment 142 to the ice bank 106, a first air inlet duct 146 and a first return duct 148 are provided between the ice bank 106 and the first chamber where the refrigerating evaporator 120 is installed, the first air inlet duct 146 communicates with between the first installation cavity 144 and the ice making compartment 102 and corresponds to the top of the ice bank 106, and the first return duct 148 communicates with between the first installation cavity 144 and the ice making compartment 102 and corresponds to the bottom of the ice bank 106. A first damper 152 is provided in the first air inlet duct 146, a second damper 154 is provided in the first return duct 148, and a first fan 174 is also provided in the first chamber in which the refrigeration evaporator 120 is installed. When the ice bank 106 needs to be cooled, the first fan 174 may be turned on, and the first air door 152 and the second air door 154 may be opened at the same time, so that the cold energy in the refrigeration evaporator 120 is blown to the ice bank 106 through the first air inlet pipe 146, and after the cold energy is blown through the ice bank 106, the heat of the ice bank 106 is taken away and flows back to the refrigeration evaporator 120 through the first air return pipe 148, so as to form an air cooling cycle for cooling the ice bank 106.

It should be noted that, the refrigeration evaporator 120 in the refrigeration compartment 142 mentioned herein may use a refrigeration compartment, or the refrigeration evaporator 120 in at least one refrigeration compartment 142 of the refrigeration evaporators 120 that cools the other refrigeration compartments 142 to cool the ice bank 106.

The implementation mode II is as follows:

in this implementation, a second fan 150 may also be provided in the ice making compartment 102, the second fan 150 being located in the air path of the refrigeration evaporator 120 in the ice bank 106 and the refrigeration compartment 142. When the ice bank 106 needs to be cooled, the second fan 150 may be turned on to guide the cold energy in the refrigeration evaporator 120 in the refrigeration compartment 142 to the ice bank 106 through the first air inlet pipe 146, and after the cold air blows through the ice bank 106, the heat of the ice bank 106 is taken away and flows back to the refrigeration evaporator 120 through the first air return pipe 148, so as to form an air cooling cycle for cooling the ice bank 106.

And the implementation mode is three:

in this implementation, an ice-making evaporator 122 may be connected in parallel to the refrigeration circuit 114, and the ice bank 106 may be cooled by the cold generated by the ice-making evaporator 122. Or a control valve may be disposed between the circulation loop of the ice making evaporator 122 and the refrigeration loop 114 of the refrigeration appliance 100, and when the ice bank 106 has a refrigeration requirement, the control valve is opened, so that the combined control of the refrigeration loop 114 of the refrigeration appliance 100 and the circulation loop of the ice making evaporator 122 can be realized.

The cooling capacity of the ice making evaporator 122 may be blown toward the ice bank 106 by adding a third fan 168 between the ice making evaporator 122 and the ice bank 106.

The implementation mode is four:

in this implementation manner, a heat exchanger 118 may be added in the above several implementation manners, the heat exchanger 118 may be cooled by the above several implementation manners, a third fan 168 is disposed between the heat exchanger 118 and the ice bank 106, and cold air with a low temperature near the heat exchanger 118 is blown to the ice bank 106 by the third fan 168.

For example, in combination with the heat exchanger 118, the first embodiment may use the refrigeration evaporator 120 in the refrigeration compartment 142 as a cold source for the heat exchanger 118, i.e., the refrigeration evaporator 120 in the refrigeration compartment 142 may be used to cool the heat exchanger 118. Accordingly, since it is necessary to guide the cold energy at the position of the heat exchanger 118 to the ice bank 106, a second air inlet duct 158 and a second return duct 160 are provided between the ice bank 106 and the second chamber where the heat exchanger 118 is installed, a third air door 162 is provided in the second air inlet duct 158, a fourth air door 164 is provided in the second return duct 160, and a first fan 174 is also provided in the first chamber where the refrigeration evaporator 120 is installed. When the ice bank 106 needs to be cooled, the first fan 174 may be turned on, and the third air door 162 and the fourth air door 164 may be simultaneously turned on, so that the cold energy in the refrigeration evaporator 120 is blown to the heat exchanger 118 through the first air inlet pipe 146, and after the cold energy is blown through the heat exchanger 118, the heat of the heat exchanger 118 is taken away and flows back to the refrigeration evaporator 120 through the first air return pipe 148. After the temperature of the heat exchanger 118 is reduced, the third fan 168, the third air door 162 and the fourth air door 164 are opened, cold air at the position of the heat exchanger 118 is blown to the ice bank 106 through the second air inlet pipe 158 by the third fan 168, heat of the ice bank 106 is taken away, and the heat flows back to the heat exchanger 118 through the second return pipe 160, so that an air cooling cycle for cooling the ice bank 106 is formed.

The implementation mode is five:

in this implementation, the cooling of the heat exchanger 118 may be achieved by the refrigeration circuit 114 of the refrigeration device 100, and a third fan 168 is disposed between the heat exchanger 118 and the ice bank 106, and cold air with a lower temperature near the heat exchanger 118 is blown to the ice bank 106 by the third fan 168.

In both implementations, the heat exchanger 118 may be flexibly disposed in the second chamber outside the ice making chamber 102 or directly installed in the ice making chamber 102 according to actual circumstances.

The implementation mode is six:

in this implementation, a third fan 168 may be added to the ice-making duct 108 at a position corresponding to the ice bank 106. As the cold storage agent flows through the ice making duct 108, the temperature of the air around the ice making duct 108 is reduced, and then cool air around the ice making duct 108 is blown to the ice bank 106 by the third fan 168.

Implementation mode seven:

in this implementation, a third fan 168 may be added to the refrigeration circuit 114 at a location corresponding to the ice bank 106. As the refrigerant flows through the refrigeration circuit 114, the temperature of the air surrounding the refrigeration circuit 114 decreases, and cool air surrounding the refrigeration circuit 114 is blown to the ice bank 106 by the third fan 168.

Implementation eight:

in such an implementation, the ice bank 106 may be directly cooled by the refrigeration compartment 142, e.g., the cold air in the refrigeration compartment may be directed to the location of the ice bank 106 to achieve the above.

Of course, in other embodiments, the several implementations described above may be combined with one another to further increase the rate of cooling to ice bank 106.

In an embodiment of the present application, the refrigeration appliance 100 further includes a controller 156, the controller 156 being adapted to switch the operating state of at least one of the ice making duct 108 and the ice storage wind duct 112 based on the operating state of the ice making compartment 102.

For example, the refrigeration device 100 provided in the embodiments of the present application may have at least the following several different operating states:

when the ice is made, the ice making loop can be independently opened, the ice storage air path 112 can be kept closed or opened, and at the moment, the quick ice making can be realized through the opening of the ice making loop;

during ice removal, the ice making loop can be closed, and the ice storage air path 112 can be opened, so that rapid ice removal can be realized, and meanwhile, the temperature in the ice storage box 106 is not influenced by heating ice removal;

during ice storage, the ice storage air duct 112 may be opened separately, and the ice making circuit may be selectively opened or closed according to ice making demands.

That is, the controller 156 can flexibly control the operating states of the ice making duct 108 and the ice storage air duct 112 in the face of the above-mentioned several different operating states, thereby realizing intelligent control.

In this way, when the ice making housing 104 is in a state of heating and de-icing, the temperature of the ice bank 106 is not affected by the heating of the ice making housing 104, and the ice storage efficiency of the ice bank 106 can be ensured. When ice making is not required, cooling of the ice bank 106 can still be achieved, avoiding melting of ice cubes in the ice bank 106.

By arranging the heat exchange tube section 110 in an inclined mode, when the ice making box 104 heats and removes ice, the cold storage agent at the bottom of the ice making box 104 can quickly flow back into the cold storage tank 176, and the heating and ice removing efficiency is ensured.
