Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and in particular to a refrigeration device and its control method and apparatus. Background Technology

[0002] In related technologies, cooling of refrigeration equipment mostly adopts air cooling. That is, the common cooling method is to add an evaporator in the ice-making chamber, and then use a fan to blow the cold air of the evaporator to the ice-making box and the ice storage box. However, when the ice-making box is heated and unfrozen, the ice storage box will also experience a temperature rise due to the temperature rise of the ice-making box. This can easily cause the ice in the ice storage box to melt, affecting the ice storage effect. Summary of the Invention

[0070] like Figures 1 to 14 As shown in the illustration, this application provides a refrigeration device 100, which includes an ice-making chamber 102 and an ice-making box 104 and an ice storage box 106 disposed inside the ice-making chamber 102. Vertically, the ice-making box 104 is positioned above the ice storage box 106. With this arrangement, after the ice-making box 104 has finished making ice, it can be flipped downwards to remove the ice, allowing the ice cubes removed from the ice-making box 104 to fall into the ice storage box 106. During the ice removal process, the ice-making box 104 can be heated by a heating wire located at its bottom to complete the ice removal.

[0071] The ice box 104 includes a box body 126, in which multiple ice tanks 130 are provided. In actual ice making, a certain amount of water can be added to the ice tanks 130, and ice making is achieved by cooling the ice box 104.

[0072] A base 128 is provided at the bottom of the ice tank 130, and a flow channel 132 is formed in the ice box 104. This flow channel 132 is used to introduce refrigerant, cold storage agent, or other refrigerant to cool the ice tank 130. Taking cold storage agent as an example, to facilitate the introduction of cold storage agent into the flow channel 132, a fluid inlet 140 and a fluid outlet 138 are provided on the flow channel 132. The fluid inlet 140 is used to introduce the cold storage agent into the flow channel 132, and the fluid outlet 138 is used to discharge the cold storage agent from the flow channel 132. It is understood that, in this embodiment, cooling the ice tank 130 can be achieved by introducing cold storage agent into the bottom of the ice tank 130. To prevent leakage of the cold storage agent, a sealing element 166 is also provided between the ice tank 130 and the base 128. For example, the sealing element 166 can be a sealing ring, a sealing gasket, etc.

[0073] It is understood that the flow groove 132 formed in the ice box 104 is the heat exchange tube section 110 in the ice making pipeline 108, and the heat exchange tube section 110 is used to realize heat exchange with the ice box 104.

[0074] In other embodiments, the heat exchange section 110 in the ice-making pipe 108 can also be formed by attaching the ice-making pipe 108 to the ice container 104. In this embodiment, the ice-making pipe 108 can be attached to the bottom or side of the ice container 104, as long as it can transfer the cold energy in the ice-making pipe 108 to the ice tank 130 in the ice container 104.

[0075] As mentioned above, in this embodiment of the application, since the cooling and refrigeration of the ice tank 130 is achieved by introducing a refrigerant, in order to ensure that the refrigerant can fully contact the ice tank 130, the ice tank 130 and the flow channel 132 provided in this embodiment of the application can be configured in at least the following ways.

[0076] Setup Method 1:

[0077] In this configuration, the bottom of the ice tank 130 can be curved, and correspondingly, the heat exchange wall 134 of the flow channel 132, corresponding to the ice tank 130, is a curved surface curving towards the bottom of the flow channel 132. For example... Figure 12 and Figure 14 As shown, the cross-sectional shape of the flow channel 132 can be approximately U-shaped. Of course, in other embodiments, the heat exchange wall 134 of the ice tank 130 corresponding to the flow channel 132 can also be set to other shapes. For example, the heat exchange wall 134 of the ice tank 130 corresponding to the flow channel 132 can be set to a wavy shape, a sawtooth shape, or other shapes, as long as the contact area between the bottom of the ice tank 130 and the flow channel 132 can be increased.

[0078] Setting method two:

[0079] In this setup, such as Figure 12 As shown, several first heat exchange structures 136 can be provided in the flow channel 132. These first heat exchange structures 136 can be fins, heat exchange plates, etc. Taking fins as an example, the fins can be set at the bottom of the ice tank 130 and extend into the flow channel 132. When the refrigerant flows through the flow channel 132, the refrigerant can fully exchange heat with the fins. Simultaneously, the fins can also create turbulence in the refrigerant. After the heat exchange between the fins and the refrigerant is completed, the fins transfer the cold energy to the ice tank 130. Alternatively, the fins can be set on the base 128, achieving the same purpose. Or, the fins can be set on both the bottom of the ice tank 130 and the base 128. In this embodiment, the fins, ice tank 130, and flow channel 132 can be integrally formed or detachably connected.

[0080] The following is a brief explanation of the fin arrangement. The fins can be arranged to extend along the length of the flow channel 132 and be spaced apart along its width. It should be noted that the spacing between adjacent fins should not be too small to prevent the fins from creating resistance to the flow of the refrigerant. Alternatively, the fins can be arranged at an angle along the length of the flow channel 132, with the angle aligned with the flow direction of the refrigerant. That is, the fins gradually angle from the refrigerant inflow direction to the refrigerant outflow direction.

[0081] Setting method 3:

[0082] In this configuration, configuration one and configuration two can be combined. That is, the heat exchange wall 134 of the flow channel 132 corresponding to the ice tank 130 is configured to be curved toward the bottom of the flow channel 132. At the same time, fins are provided on at least one of the bottom of the ice tank 130 and the base 128 to improve the heat exchange efficiency between the refrigerant and the ice tank 130.

[0083] Setting method four:

[0084] In this configuration, along the length of the flow channel 132, as shown in the example... Figure 14 Several baffles are spaced apart on the two opposite side walls of the flow channel 132 in the left and right directions. The adjacent baffles are staggered. This arrangement allows the refrigerant to flow in a tortuous path after entering the flow channel 132. This prolongs the flow time of the refrigerant in the flow channel 132, thereby prolonging the contact time between the refrigerant and the ice tank 130, so that the refrigerant and the ice tank 130 can have sufficient heat exchange.

[0085] Of course, other methods can also be used to improve the heat exchange efficiency between the ice tank 130 and the refrigerant. For example, the flow channel 132 can be directly set into a bent shape. By setting the flow channel 132 into a bent shape, the flow time of the refrigerant in the flow channel 132 can be extended, which can correspondingly extend the contact time between the refrigerant and the ice tank 130, thereby achieving comprehensive cooling and refrigeration of the ice tank 130.

[0086] According to one embodiment of this application, in order to provide driving force for the flow of the refrigerant, a driving element 116 is also provided on the ice-making pipeline 108, which may be a pump.

[0087] When refrigerant is introduced into the flow channel 132, the ice-making circuit can be directly connected to the refrigeration circuit 114. The ice-making circuit can be connected in parallel to the evaporator circuit of the cold storage compartment, or in parallel to the evaporator circuit of the freezer compartment, or directly in series with the refrigeration circuit 114 of the refrigeration equipment 100.

[0088] In this embodiment, the cooling method of the ice tank 130 is achieved by introducing refrigerant, cold storage agent and other refrigerant into the flow channel 132.

[0089] In this embodiment, the cooling method for the refrigerant can be achieved by connecting the ice-making pipeline 108 to the heat exchanger 118.

[0090] By connecting the ice-making pipeline 108 to the heat exchanger 118, the ice-making pipeline 108 can be cooled. When the temperature of the ice-making pipeline 108 decreases, the cooling capacity can be transferred to the refrigerant within it. Therefore, the heat exchanger 118 is equipped with a first inlet pipe for introducing the refrigerant and a first outlet pipe for discharging the refrigerant. These two pipes constitute a refrigerant pipe 124 for the circulation of the refrigerant. Cooling of the refrigerant pipe 124 can be achieved using a refrigeration evaporator 120 in the refrigeration compartment, a refrigeration evaporator 120 in the freezer compartment, or a refrigeration evaporator 120 supplying cooling to other refrigeration compartments 142.

[0091] In order to improve the heat exchange performance of heat exchanger 118, a second heat exchange structure 170 is also provided on heat exchanger 118. The second heat exchange structure 170 can be a structure such as fins or protrusions formed on the surface of heat exchanger 118 that can increase the surface area of ​​heat exchanger 118.

[0092] In this embodiment of the application, the heat exchanger 118 can adopt at least the following forms of heat exchange:

[0093] Heat exchange method 1:

[0094] In this heat exchange method, such as Figure 1As shown, the heat exchanger 118 can be cooled by the evaporator 120 in the cooling chamber 142. The evaporator 120 is installed in the first mounting cavity 144 of the cooling chamber 142. Accordingly, since it is necessary to guide the cooling capacity of the evaporator 120 in the cooling chamber 142 to the heat exchanger 118, a first air inlet pipe 146 and a first air return pipe 148 are provided between the heat exchanger 118 and the evaporator 120 in the cooling chamber 142. A first damper 152 is provided in the first air inlet pipe 146, and a second damper 154 is provided in the first air return pipe 148. A first fan 174 is also provided in the first cavity where the evaporator 120 is installed. When the heat exchanger 118 needs to be cooled, the first fan 174 can be turned on, and the first damper 152 and the second damper 154 can be opened at the same time. The cold air in the evaporator 120 is blown to the heat exchanger 118 through the first air inlet pipe 146. After the cold air blows through the heat exchanger 118, it carries away the heat of the heat exchanger 118 and flows back to the evaporator 120 through the first return air pipe 148, thus forming a wind-cooled cycle to cool the heat exchanger 118.

[0095] When the refrigerant flows into the heat exchanger 118 through the first inlet pipe, it can achieve cooling by exchanging heat with the heat exchanger 118. When the refrigerant flows out of the heat exchanger 118 through the first outlet pipe, it can enter the flow tank 132 to achieve cooling of the ice tank 130.

[0096] It should be noted that the evaporator 120 in the refrigeration compartment 142 mentioned here can be used in the refrigeration compartment, the freezer compartment, or the evaporator 120 in the refrigeration compartment 142 that supplies cooling to other refrigeration compartments 142 to cool the heat exchanger 118.

[0097] Heat exchange method two:

[0098] In this heat exchange method, unlike the first method, a second fan 150 can be installed in the ice-making chamber 102. When the heat exchanger 118 needs cooling, the second fan 150 can be turned on, drawing the cooling energy from the evaporator 120 in the cooling chamber 142 to the heat exchanger 118 through the first air inlet duct 146. The cold air blown across the heat exchanger 118 carries away its heat and flows back to the evaporator 120 through the first return air duct 148, thus forming a cooling air circulation system for the heat exchanger 118. This allows for separate cooling of the cooling chamber 142 and the heat exchanger 118 by adding the second fan 150. That is, when the cooling chamber 142 needs cooling, the first fan 174 can be turned on independently; when the heat exchanger 118 needs heat exchange, both the first fan 174 and the second fan 150 can be turned on simultaneously.

[0099] When the refrigerant flows into the heat exchanger 118 through the first inlet pipe, it can achieve cooling by exchanging heat with the heat exchanger 118. When the refrigerant flows out of the heat exchanger 118 through the first outlet pipe, it can enter the flow tank 132 to achieve cooling of the ice tank 130.

[0100] It should be noted that the evaporator 120 in the refrigeration compartment 142 mentioned here can be used to cool the heat exchanger 118 by using at least one of the evaporators 120 in the refrigeration compartment, the freezer compartment, or the evaporators 120 that supply cooling to other refrigeration compartments 142.

[0101] Heat exchange method three:

[0102] In this heat exchange method, the heat exchanger 118 can be cooled by the refrigeration circuit 114 of the refrigeration equipment 100. Therefore, in addition to a first inlet pipe and a first outlet pipe for the flow of the refrigerant, the heat exchanger 118 also has a second inlet pipe for introducing the refrigerant and a second outlet pipe for discharging the refrigerant. When the refrigerant in the refrigeration equipment flows into the heat exchanger 118 through the second inlet pipe, it cools the heat exchanger 118 and removes its heat. The refrigerant then flows out of the heat exchanger 118 through the second outlet pipe and enters the refrigeration circuit 114 of the refrigeration equipment 100, thus forming a liquid-cooled cycle for the heat exchanger 118.

[0103] When the refrigerant flows into the heat exchanger 118 through the first inlet pipe, it can achieve cooling by exchanging heat with the heat exchanger 118. When the refrigerant flows out of the heat exchanger 118 through the first outlet pipe, it can enter the flow tank 132 to achieve cooling of the ice tank 130.

[0104] In the three heat exchange methods described above, the heat exchanger 118 can be installed in the ice-making chamber 102. Correspondingly, a second mounting cavity can be provided in the ice-making chamber 102 for installing the heat exchanger 118. For example, the second mounting cavity can be located on the outside of the ice-making chamber 102, thus avoiding the heat exchanger 118 occupying internal space within the ice-making chamber 102. The heat exchanger 118 can also be installed in other refrigeration chambers 142. It is understood that the second mounting cavity mentioned here refers to the installation space 178 of the heat exchanger 118, and the working space 180 of the ice-making chamber 102 is the internal space during actual ice making.

[0105] Heat exchange method four:

[0106] In this heat exchange method, an ice-making evaporator 122 can be connected in parallel in the refrigeration circuit 114, and heat exchange can be performed on the heat exchanger 118 through the ice-making evaporator 122. Alternatively, a control valve can be installed between the circulation loop of the ice-making evaporator 122 and the refrigeration circuit 114 of the refrigeration equipment 100. When there is a demand for ice making, the control valve is opened, which can realize the combined control of the circulation loop of the refrigeration circuit 114 of the refrigeration equipment 100 and the circulation loop of the ice-making evaporator 122.

[0107] The ice-making evaporator 122 and the heat exchanger 118 can be connected via piping, or the cold air from the ice-making evaporator 122 can be blown to the heat exchanger 118 via air cooling. For example, in this heat exchange method, the heat exchanger 118 can be connected to the ice-making evaporator 122 via a microchannel, in which case the heat exchanger 118 can be placed in the second mounting cavity on the ice-making chamber 102. Furthermore, connecting the heat exchanger 118 and the ice-making evaporator 122 via a microchannel allows for a smaller structure of the heat exchanger 118, achieving miniaturization, and also results in lower heat loss.

[0108] Of course, in some other embodiments, the above-mentioned cooling methods can be combined to further improve the cooling rate of heat exchanger 118.

[0109] According to one embodiment of this application, when ice making is finished and de-icing is required, in order to ensure that the refrigerant in the flow channel 132 flows back as quickly as possible, the ice-making box 104 can be set in an inclined form, or only the heat exchange tube section 110 in the ice-making circuit can be set in an inclined form. It is understood that, in order to achieve the above purpose, the fluid outlet 138 of the heat exchange tube section 110 can be set to be located at the lowest point of the heat exchange tube section 110.

[0110] like Figure 3 As shown, the heat exchanger 118 for exchanging heat with the refrigerant, the drive unit 116 for driving the flow of the refrigerant, and the refrigerant storage tank 176 can be positioned near the rear of the refrigeration equipment 100. Therefore, the tilt direction of the ice-making box 104 can gradually slope downwards from the fluid inlet 140 of the heat exchange tube section 110 towards the fluid outlet 138 of the heat exchange tube section 110. That is, see [reference needed]. Figure 3When the heat exchanger 118, drive unit 116, and cold storage tank 176 are positioned near the rear of the refrigeration equipment 100, the left side of the ice-making box 104 can be positioned relatively higher, and the right side relatively lower. Correspondingly, the left side of the heat exchange tube section 110 is positioned relatively higher, and the right side relatively lower. This way, after ice making is complete, the refrigerant in the flow channel 132 can quickly flow back to the cold storage tank 176 under gravity. This avoids the problem of slow heating rate of the heating wire due to refrigerant remaining in the flow channel 132, thereby improving the de-icing efficiency.

[0111] In some other embodiments, the heat exchange tube section 110 may also be configured in a stepped manner, that is, the heat exchange tube section 110 may be configured to decrease in a stepped manner from the direction of fluid inlet 140 to the direction of fluid outlet 138.

[0112] In this embodiment, to further improve the refrigerant reflux rate, the storage volume of the refrigerant tank 176 is larger than the total volume of the refrigerant in the ice-making pipeline 108. That is, assuming the total volume of the refrigerant flowing in the ice-making pipeline 108 is 4 liters, the storage volume of the refrigerant tank 176 is 5 liters. With this configuration, after ice making is complete, the refrigerant in the ice-making pipeline 108 can quickly reflux back into the refrigerant tank 176. As a result, when the heating wire is working, no refrigerant remains in the flow channel 132, thus ensuring the heating efficiency of the heating wire for the ice tank 130 and achieving rapid de-icing.

[0113] In this embodiment, the cooling method for the ice storage box 106 is achieved by air cooling, and correspondingly, the refrigeration device 100 includes an ice storage air passage 112. As mentioned above, since the ice making box 104 makes ice through the ice making pipe 108, and the ice storage box 106 stores ice through the ice storage air passage 112, when the ice making box 104 is in a state of heating and de-icing, the ice storage box 106 can achieve low-temperature ice storage independently through the ice storage air passage 112. Therefore, the temperature of the ice storage box 106 will not be affected by the heating and de-icing, thereby preventing the ice stored in the ice storage box 106 from melting and ensuring the ice storage effect of the ice storage box 106.

[0114] In this embodiment of the application, the cold source of the ice storage air path 112 can be at least the following different cold sources:

[0115] Implementation method 1:

[0116] In this implementation, such as Figure 1As shown, the evaporator 120 in the refrigeration chamber 142 can be used as the cold source for the ice storage air path 112, that is, the cooling capacity of the evaporator 120 in the refrigeration chamber 142 can be used to cool the ice storage box 106. Accordingly, since it is necessary to guide the cooling capacity of the evaporator 120 in the refrigeration chamber 142 to the ice storage box 106, a first air inlet pipe 146 and a first air return pipe 148 are provided between the ice storage box 106 and the first chamber where the evaporator 120 is installed. The first air inlet pipe 146 connects the first mounting cavity 144 and the ice-making chamber 102 and corresponds to the top of the ice storage box 106. The first air return pipe 148 connects the first mounting cavity 144 and the ice-making chamber 102 and corresponds to the bottom of the ice storage box 106. A first damper 152 is installed in the first air inlet duct 146, and a second damper 154 is installed in the first return air duct 148. A first fan 174 is also installed in the first chamber where the evaporator 120 is installed. When the ice storage box 106 needs to be cooled, the first fan 174 can be turned on, and the first damper 152 and the second damper 154 can be opened at the same time. The cold air in the evaporator 120 is blown to the ice storage box 106 through the first air inlet duct 146. After the cold air blows over the ice storage box 106, it carries away the heat of the ice storage box 106 and flows back to the evaporator 120 through the first return air duct 148, thus forming a wind-cooled cycle to cool the ice storage box 106.

[0117] It should be noted that the evaporator 120 in the refrigeration compartment 142 mentioned here can be used to cool the ice storage box 106 by using at least one of the evaporators 120 in the refrigeration compartment, the freezer compartment, or the evaporators 120 that supply cooling to other refrigeration compartments 142.

[0118] Implementation Method Two:

[0119] In this implementation, unlike the first implementation, a second fan 150 can be installed in the ice-making chamber 102. The second fan 150 is located in the air path between the ice storage box 106 and the evaporator 120 in the cooling chamber 142. When the ice storage box 106 needs to be cooled, the second fan 150 can be turned on to draw the cold air from the evaporator 120 in the cooling chamber 142 to the ice storage box 106 through the first air inlet pipe 146. After the cold air blows across the ice storage box 106, it carries away the heat from the ice storage box 106 and flows back to the evaporator 120 through the first air return pipe 148, thus forming a wind-cooled cycle to cool the ice storage box 106.

[0120] It should be noted that the evaporator 120 in the refrigeration compartment 142 mentioned here can be used to cool the ice storage box 106 by using at least one of the evaporators 120 in the refrigeration compartment, the freezer compartment, or the evaporators 120 that supply cooling to other refrigeration compartments 142.

[0121] Implementation method three:

[0122] In this implementation, an ice-making evaporator 122 can be connected in parallel with the refrigeration circuit 114, and the cooling capacity generated by the ice-making evaporator 122 can be used to cool the ice storage box 106. Alternatively, a control valve can be installed between the circulation loop of the ice-making evaporator 122 and the refrigeration circuit 114 of the refrigeration device 100. When the ice storage box 106 has a cooling demand, the control valve is opened, which can realize the combined control of the refrigeration circuit 114 of the refrigeration device 100 and the circulation loop of the ice-making evaporator 122.

[0123] The cold air from the ice evaporator 122 can be blown towards the ice storage box 106 by adding a third fan 168 between the ice evaporator 122 and the ice storage box 106.

[0124] Implementation Method 4:

[0125] In this implementation, a heat exchanger 118 can be added to each of the above implementation methods, and the heat exchanger 118 can be cooled down by the above implementation methods. Then, a third fan 168 is set between the heat exchanger 118 and the ice storage box 106, and the cold air with a lower temperature near the heat exchanger 118 is blown to the ice storage box 106 by the third fan 168.

[0126] For example, by combining the first implementation method with the heat exchanger 118, the refrigeration evaporator 120 in the refrigeration chamber 142 can be used as the cold source for the heat exchanger 118. That is, the cooling capacity of the refrigeration evaporator 120 in the refrigeration chamber 142 can be used to cool the heat exchanger 118. Correspondingly, since it is necessary to guide the cooling capacity at the location of the heat exchanger 118 to the ice storage box 106, a second air inlet pipe 158 and a second air return pipe 160 are provided between the ice storage box 106 and the second chamber where the heat exchanger 118 is installed. A third damper 162 is provided in the second air inlet pipe 158, and a fourth damper 164 is provided in the second air return pipe 160. A first fan 174 is also provided in the first chamber where the refrigeration evaporator 120 is installed. When the ice storage box 106 needs to be cooled, the first fan 174 can be turned on, and the third damper 162 and the fourth damper 164 can be opened simultaneously. The cold air in the evaporator 120 is blown to the heat exchanger 118 through the first air inlet pipe 146. After the cold air passes through the heat exchanger 118, it carries away the heat of the heat exchanger 118 and flows back to the evaporator 120 through the first return air pipe 148. After the temperature of the heat exchanger 118 drops, the third fan 168, the third damper 162, and the fourth damper 164 are turned on. The third fan 168 blows the cold air at the location of the heat exchanger 118 through the second air inlet pipe 158 to the ice storage box 106, carrying away the heat of the ice storage box 106 and flowing back to the heat exchanger 118 through the second return air pipe 160, thus forming a wind-cooled circulation to cool the ice storage box 106.

[0127] Implementation Method 5:

[0128] In this implementation, the heat exchanger 118 can be cooled by the refrigeration circuit 114 of the refrigeration equipment 100, and a third fan 168 is set between the heat exchanger 118 and the ice storage box 106. The lower temperature cold air near the heat exchanger 118 is blown to the ice storage box 106 by the third fan 168.

[0129] In the two implementation methods described above, the heat exchanger 118 can be flexibly set in the second chamber outside the ice-making chamber 102 or directly installed inside the ice-making chamber 102, depending on the actual situation.

[0130] Implementation method six:

[0131] In this implementation, a third fan 168 can be added at the corresponding positions of the ice-making pipe 108 and the ice storage box 106. When the refrigerant flows through the ice-making pipe 108, the air temperature around the ice-making pipe 108 decreases, and then the third fan 168 blows the cold air around the ice-making pipe 108 to the ice storage box 106.

[0132] Implementation method seven:

[0133] In this implementation, a third fan 168 can be added at the position corresponding to the refrigeration circuit 114 and the ice storage box 106. When the refrigerant flows through the refrigeration circuit 114, the air temperature around the refrigeration circuit 114 decreases, and then the third fan 168 blows the cold air around the refrigeration circuit 114 to the ice storage box 106.

[0134] Implementation method eight:

[0135] In this implementation, the ice storage box 106 can be cooled directly through the cooling chamber 142. For example, the cold air in the freezing chamber can be directly introduced to the location of the ice storage box 106 to achieve the above purpose.

[0136] Of course, in other embodiments, the above-mentioned implementation methods can be combined to further improve the cooling rate of the ice storage box 106.

[0137] In this embodiment of the application, the refrigeration device 100 further includes a controller 156, which is adapted to switch the operating state of at least one of the ice-making pipeline 108 and the ice storage air pipeline 112 based on the operating state of the ice-making chamber 102.

[0138] For example, the refrigeration device 100 provided in this application embodiment can have at least the following different operating states:

[0139] During ice making, the ice making circuit can be turned on independently, while the ice storage air circuit 112 can be kept closed or turned on. At this time, the ice making circuit can be turned on to achieve rapid ice making.

[0140] During de-icing, the ice-making circuit can be turned off and the ice storage air path 112 can be turned on. At this time, rapid de-icing can be achieved, while ensuring that the temperature in the ice storage box 106 is not affected by heating de-icing.

[0141] During ice storage, the ice storage air circuit 112 can be turned on separately, and the ice making circuit can be turned on or off depending on the ice making needs.

[0142] That is, when faced with the above-mentioned different working states, the controller 156 can flexibly control the working state of the ice-making pipeline 108 and the ice storage air pipeline 112 to achieve intelligent control.

[0143] In this embodiment, liquid cooling is used to cool the ice-making container 104, and air cooling is used to cool the ice storage container 106. This allows for separate cooling of both the ice-making container 104 and the ice storage container 106, and these two cooling processes can be independent of each other. Therefore, when the ice-making container 104 is in a heating and de-icing state, the temperature of the ice storage container 106 is not affected by the heating of the ice-making container 104, ensuring the ice storage efficiency of the ice storage container 106. Even when ice making is not required, the ice storage container 106 can still be cooled, preventing the ice in the ice storage container 106 from melting.

[0144] By setting the heat exchange tube section 110 in an inclined form, it can be ensured that when the ice box 104 is heated and de-iced, the refrigerant at the bottom of the ice box 104 can quickly flow back to the cold storage tank 176, thus ensuring the efficiency of heating and de-icing.

[0145] By setting a first heat exchange structure 136 in the flow channel 132 of the ice box 104, or by setting the heat exchange wall 134 of the flow channel 132 corresponding to the ice tank 130 in an arc shape, the contact area between the refrigerant and the ice tank 130 can be increased, thereby improving the ice-making efficiency.

[0146] In this embodiment, the refrigeration device 100 may be an ice-making component 172 (i.e., an ice maker), a refrigerator, a freezer, etc.

[0147] like Figure 15 As shown, this application also provides a control method for a refrigeration device, comprising:

[0148] Step 10: Confirm that the ice-making chamber 102 has entered the freezing state, and control the ice-making pipeline 108 and the ice storage air pipeline 112 to open;

[0149] Step 20: Determine whether the ice chamber 102 has entered the de-icing or defrosting state, and disconnect the ice-making pipeline 108.

[0150] In step 10, if the ice-making chamber 102 enters the freezing state, the ice-making pipeline 108 and the ice storage air pipeline 112 are opened simultaneously to reduce the temperature inside the ice-making chamber 102, which makes ice making more convenient.

[0151] In step 20, if the ice chamber 102 enters the de-icing or defrosting state, the ice making pipeline 108 is closed to facilitate the de-icing and defrosting of the ice box 104. At this time, the ice storage air pipeline 112 can be turned on or off according to the ice storage status in the ice storage box 106.

[0152] According to one embodiment of this application, it also includes:

[0153] Step 21: Determine whether the ice container 104 has entered the de-icing or defrosting state, and control the ice storage air path 112 to open.

[0154] In step 21, if the ice box 104 enters the de-icing state or the defrosting state, it proves that there is a need for de-icing. In order to ensure that the ice in the ice storage box 106 is not affected by de-icing or defrosting, the ice storage air passage 112 is opened to cool the ice storage box 106.

[0155] According to one embodiment of this application, it also includes:

[0156] Step 22: Confirm that the ice storage box 106 contains ice, and control the ice storage air passage 112 to open;

[0157] Step 23: Ensure that the ice storage box 106 does not contain ice, and shut off the ice storage air passage 112.

[0158] In step 22, when ice is stored in the ice storage box 106, in order to ensure that the ice is dry and hard, the ice storage air passage 112 is opened to cool the ice storage box 106.

[0159] In step 23, when there is no ice in the ice storage box 106, the ice storage air path 112 is shut off in order to reduce energy consumption.

[0160] According to one embodiment of this application, it also includes:

[0161] Step 24: Confirm that the ice storage box 106 is full of ice and control the ice storage air path 112 to open.

[0162] In step 24, if the ice storage box 106 is full of ice, in order to ensure that the ice is dry and hard, the ice storage air passage 112 is opened to cool the ice storage box 106.

[0163] like Figure 16 As shown in the illustration, this application also provides a control device for a refrigeration equipment, comprising:

[0164] The first control module 182 is used to determine that the ice-making chamber 102 has entered the freezing state and to control the ice-making pipeline 108 and the ice-storage air path 112 to open.

[0165] The second control module 184 is used to determine whether the ice-making chamber 102 enters the de-icing state or the defrosting state, and to control the ice-making pipeline 108 to disconnect.

[0166] like Figure 17As shown in the diagram, this application also provides a schematic diagram of the physical structure of an electronic device, which may include: a processor 186, a communication interface 188, a memory 190, and a communication bus 192, wherein the processor 186, the communication interface 188, and the memory 190 communicate with each other through the communication bus 192. The processor 186 can call logical instructions in the memory 190 to execute the following method:

[0167] Once the ice-making chamber 102 is confirmed to be in freezing mode, the ice-making pipeline 108 and the ice-storage air pipeline 112 are turned on.

[0168] Once the ice-making chamber 102 is confirmed to be in the de-icing or defrosting state, the ice-making pipeline 108 is disconnected.

[0169] Furthermore, the logical instructions in the aforementioned memory 190 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.
