DETAILED DESCRIPTION

[0027] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0028] It should be noted that the terms "upper", "lower", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the auxiliary drawing, and are only for the convenience of simplifying the description of the present application, and do not indicate or imply that the device must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application. Specifically, in the present application, the user's operation surface is taken as the front, and the direction towards the ground is taken as the lower, and conversely, the direction away from the ground is taken as the upper, and other orientation descriptions are defined based on "upper" and "lower".

[0029] In various drawings of the present application, some dimensions of structures or parts may be exaggerated relative to other structural parts for the convenience of illustration, and therefore, are only used to illustrate the basic structure of the subject matter of the present application.

[0030] The application provides a control method of a refrigeration device and the refrigeration device, wherein the control method is based on the structure of the refrigeration device, and the refrigeration device is used to execute the control method to realize ice making and refrigeration of a refrigeration compartment. The refrigeration device of the application includes but is not limited to a household refrigerator, a refrigeration wine cabinet and a vehicle-mounted refrigerator, etc. The following will take the vehicle-mounted refrigerator as an example to be described in detail.

[0031] As shown in Figures 1 to 3 The refrigeration device includes a refrigeration system 1 and a refrigeration compartment 2 and an ice making compartment 3, wherein the refrigeration system 1 includes a compressor 40 and a condenser 50 connected to the outlet side of the compressor 40, the compressor 40 is arranged at the bottom of the refrigeration compartment 2, and the refrigeration system 1 further includes a first refrigeration circuit 10 and a second refrigeration circuit 20 connected to the outlet side of the condenser 50 and the inlet side of the compressor 1 in parallel.

[0032] As shown in Figure 3 The first refrigeration circuit 10 is used to provide cold energy to the ice making compartment 3, and the first refrigeration circuit 10 includes an ice making evaporator 11, a first capillary tube 12 connected to the inlet side of the ice making evaporator 11, and a first valve 13 connected between the inlet side of the first capillary tube 12 and the condenser 50, the first valve 13 is located upstream of the ice making evaporator 11; the second refrigeration circuit 20 is used to provide cold energy to the refrigeration compartment 2, and the second refrigeration circuit 20 includes a refrigeration evaporator 21, a second capillary tube 22 connected to the inlet side of the refrigeration evaporator 21, and a second valve 23 connected between the second capillary tube 22 and the condenser 50, the second valve 23 is located upstream of the refrigeration evaporator 21.

[0033] In order to fully utilize the refrigerant flowing out of the ice making evaporator 11, the refrigeration system 1 further includes a connecting pipeline 3 connected between the outlet side of the ice making evaporator 11 and the inlet side of the refrigeration evaporator 21, and a third valve 31 arranged on the connecting pipeline 3, the third valve 31 is used to control the connection or closing of the outlet side of the ice making evaporator 11 and the inlet side of the refrigeration evaporator 21, when the third valve 31 is in an open state, the refrigerant flowing out of the ice making evaporator 11 enters the refrigeration evaporator 21 again to continue to provide cold energy to the refrigeration compartment 2.

[0034] Understandably, opening the third valve 31 is to allow the refrigerant flowing out of the homemade ice evaporator 11 to re-enter the refrigeration evaporator 21. When the third valve 31 is opened, in order to prevent the refrigerant flowing out of the homemade ice evaporator 11 from flowing directly to the compressor 40, the first refrigeration circuit 10 also includes a fourth valve 14 connecting the outlet side of the ice evaporator 11 and the inlet side of the compressor 40. Generally speaking, the closing states of the third valve 31 and the fourth valve 14 are opposite. That is, when the third valve 31 is opened, the refrigerant flowing out of the outlet side of the homemade ice evaporator 11 flows into the refrigeration evaporator 21, and when the fourth valve 14 is opened, the refrigerant flowing out of the outlet side of the homemade ice evaporator 11 flows into the compressor 40.

[0035] In order to avoid insufficient evaporation of the refrigerant from the homemade ice evaporator 11, the first refrigeration circuit 10 also includes a liquid storage tank 15 located between the outlet of the ice evaporator 11 and the inlet of the compressor 40. The insufficiently evaporated refrigerant can be temporarily stored in the liquid storage tank 15 before entering the compressor 40.

[0036] It is understandable that the first valve 13 and the second valve 23 can also be three-way valves located at the intersection of the outlet side of the adjacent condenser 50 of the first refrigeration circuit 10 and the second refrigeration circuit 20. The third valve 31 and the fourth valve 14 can also be three-way valves located on the outlet side of the ice evaporator 11, which can also achieve the purpose of controlling the refrigerant flow.

[0037] like Figure 1 As shown, in the vehicle refrigerator, the ice-making chamber 3 is an ice bucket 301 located on the side of the refrigerator compartment 2. The ice bucket 301 is located above the condenser 50, which reduces the piping layout in the refrigeration system 1, reduces the loss of cold energy, and thus improves the efficiency of ice making. Moreover, the ice bucket 301 and the refrigerator compartment 2 are arranged horizontally, which does not affect the setting and space of the refrigerator compartment 2, and also improves the overall layout of the vehicle refrigerator, making the entire vehicle refrigerator compact and small.

[0038] In an optional embodiment, the ice-making evaporator 11 is a spiral-shaped ice-making evaporator tube, which is wound around and tightly fitted to the outside of the ice bucket 301, thereby increasing the ice-making rate through direct cooling. In this embodiment, the outer wall of the ice bucket 301 is provided with a first groove (not shown) for accommodating the ice-making evaporator tube. The first groove is used to fix the ice-making evaporator tube and also reduces the distance between the ice-making evaporator tube and the inside of the ice bucket 301, further improving the efficiency of cold exchange between the ice-making evaporator tube and the inside of the ice bucket 301.

[0039] like Figure 2As shown, the refrigeration device further comprises a liquid storage container 302 sleeved outside the ice bucket 301, the ice-making evaporator 11 is attached between the ice bucket 301 and the liquid storage container 302, the liquid storage container 302 is provided with a second groove (not shown) on the wall surface close to the ice bucket 301, the first groove and the second groove are correspondingly arranged, and the first groove and the second groove cooperate to form a storage space for accommodating the ice-making evaporator, so that the ice-making evaporator 11 provides cold energy for the liquid storage container 302 and the ice bucket 301. Generally, water or beverage liquid to be cooled is added into the liquid storage container 302, and the cold energy of the ice-making evaporator 11 is used to cool the to-be-cooled object to make cold drinks, meet the diversified needs of users, and improve the user experience.

[0040] The liquid storage container 302 comprises a first container 3021 and a second container 3022 which are respectively matched with the ice-making evaporator 11, and the first container 3021 and the second container 3022 are installed or detached outside the ice bucket 301 along the radial direction of the ice bucket 301, so that the first container 3021 and the second container 3022 can be easily matched with the ice-making evaporator 11. In an optional embodiment, the first container 3021 and the second container 3022 are both semicircular, and form a ring after being butt-jointed along the radial direction of the ice bucket 301, so as to fully utilize the cold energy of the ice-making evaporator 11. Of course, the first container 3021 and the second container 3022 can also be smaller than semicircle, and can also be installed or detached on the ice-making evaporator 11 along the radial direction of the ice bucket 301.

[0041] In an optional embodiment, the thermal conductivity coefficient of the material of the ice bucket 301 is greater than that of the material of the liquid storage container 302. When there are to-be-cooled liquids in the ice bucket 301 and the liquid storage container 302, the liquid in the ice bucket 301 can absorb more cold energy than the liquid in the liquid storage container 302. When ice making and cold drink making are performed simultaneously, the liquid in the liquid storage container 302 will not be too cold. It can be understood that ice making and cold drink making can be performed simultaneously or separately, and both do not affect the performance of the other.

[0042] The control method of the refrigeration device of the present application controls the flow direction of the refrigerant in the refrigeration system 1 to provide cold energy to the ice-making chamber 3 and / or the cold storage chamber 2. In the conventional refrigeration mode, the second valve 23 is always in the open state to supply cold energy to the cold storage chamber, and the first valve 13 and the third valve 31 are in the closed state, and the second refrigeration circuit 20 works normally.

[0043] Based on the structure of the above refrigeration device, as Figures 4 to 6As shown, the control method comprises: obtaining a signal indicating whether the refrigeration device needs to make ice; if yes, entering an ice-making mode, obtaining whether the temperature in the refrigeration compartment 2 reaches a first start-up point temperature, if yes, pausing the ice-making mode, and performing an intermediate refrigeration mode on the refrigeration compartment 2; if no, continuing to run the ice-making mode; and if no, performing a normal refrigeration mode on the refrigeration compartment 2.

[0044] The control method of the refrigeration device of the present application changes the length of time during which the refrigeration compartment 2 stops cooling by controlling the start-up point temperature of the refrigeration compartment, and further controls the demand of the refrigeration compartment 2 for cooling, so as to ensure the smooth progress of ice-making and improve the user experience.

[0045] In an optional embodiment, the first start-up point temperature is higher than the second start-up point temperature in the normal refrigeration mode, that is, the start-up point temperature of the refrigeration compartment is increased, the length of time during which the refrigeration compartment 2 stops cooling is increased, the demand of the refrigeration compartment 2 for cooling is delayed, sufficient time is provided for ice-making, the smooth progress of ice-making is ensured, and the user experience is improved.

[0046] Of course, the first start-up point temperature can also be equal to or lower than the second start-up point temperature in the normal refrigeration mode. The user can set the settings of the intermediate refrigeration mode according to the total amount of pre-made ice cubes and / or the amount of items in the refrigeration compartment 2, reasonably allocate the cooling capacity, and improve the user experience.

[0047] In an optional embodiment, the signal indicating that the refrigeration device needs to make ice is obtained, the refrigeration compartment 2 is subjected to a normal refrigeration mode before entering the ice-making mode, and then the ice-making mode is entered after the normal refrigeration mode ends. The refrigeration compartment 2 is provided with sufficient cooling capacity before ice-making, so as to ensure the preservation of items in the refrigeration compartment 2 during ice-making.

[0048] The ice-making mode specifically comprises opening the first valve 13 upstream of the ice-making evaporator 11 in the first refrigeration circuit 10, and closing the second valve 23 upstream of the refrigeration evaporator 21 in the second refrigeration circuit 20. The refrigerant flows into the ice-making evaporator 11 to cool the ice bucket 301. In the above-mentioned ice-making mode, the first refrigeration circuit 10 works, the third valve 31 is in a closed state, and the fourth valve 14 is in an open state.

[0049] As a preferred embodiment of the control method of the refrigeration device of the present application, as shown in Figure 5As shown, in the ice-making mode, the temperature in the refrigeration compartment 2 reaches the first start-up point temperature, and the ice-making duration is further obtained. It is determined whether the ratio of the ice-making duration to the preset total ice-making duration is not less than one-half. If the ratio of the ice-making duration to the preset total ice-making duration is not less than one-half, it indicates that the ice-making mode has been over half. In order for the user to obtain ice cubes in time, the ice-making mode is continued, and after the ice-making is completed, the refrigeration compartment 2 is subjected to the normal cooling mode. If the ratio of the ice-making duration to the preset total ice-making duration is less than one-half, it indicates that the ice-making duration is relatively short, and the duration to the end of ice-making is relatively long. If the refrigeration compartment 2 is cooled after the ice-making mode is completed, the preservation of the refrigeration compartment 2 is greatly affected. Therefore, the ice-making mode is suspended, and the refrigeration compartment 2 is subjected to the intermediate cooling mode.

[0050] As a preferred embodiment of the control method of the refrigeration equipment, as shown in Figure 6 As shown, in the ice-making mode, the temperature in the refrigeration compartment 2 reaches the first start-up point temperature, and the ice-making duration is further obtained. It is determined whether the ratio of the ice-making duration to the preset total ice-making duration is not less than one-half. If the ratio of the ice-making duration to the preset total ice-making duration is not less than one-half, it indicates that the ice-making mode has been over half. In order for the user to obtain ice cubes in time, the ice-making mode is continued, and after the ice-making is completed, the refrigeration compartment 2 is subjected to the normal cooling mode. If the ratio of the ice-making duration to the preset total ice-making duration is less than one-half, it indicates that the ice-making duration is relatively short, and the duration to the end of ice-making is relatively long. If the refrigeration compartment 2 is cooled after the ice-making mode is completed, the preservation of the refrigeration compartment 2 is greatly affected. Therefore, the ice-making mode is suspended, and the refrigeration compartment 2 is subjected to the intermediate cooling mode.

[0051] The intermediate cooling mode is specifically that the first valve 13 is closed, and the second valve 23 is opened. At this time, the first refrigeration circuit 10 stops working, and the second refrigeration circuit 20 starts working. The refrigerant only flows through the refrigeration evaporator 21 to cool the refrigeration compartment 2 until the temperature of the refrigeration compartment 2 reaches the first shutdown point temperature. The ice-making mode is continued. The first shutdown point temperature is not lower than the normal shutdown point temperature in the normal cooling mode. That is, the intermediate cooling mode of the refrigeration compartment 2 is only compensatory cooling for the temperature rise in the refrigeration compartment 2 in the ice-making mode. The refrigeration effect of the intermediate cooling mode on the refrigeration compartment 2 may not reach the effect of the normal cooling mode. Since the duration of the intermediate cooling mode is relatively short, the refrigerant can be switched to the ice-making evaporator 11 as soon as possible, thereby accelerating the ice-making process.

[0052] In the ice-making mode, if it is obtained that there is to-be-cooled material in the storage container 302 sleeved outside the ice bucket 301, the temperature in the storage container 302 is obtained, it is judged whether the temperature in the storage container 302 reaches a preset temperature, if yes, an alarm is sent to remind the user that the to-be-cooled material in the storage container 302 has met the requirement, and the cold drink of the storage container 302 is taken away in time to avoid the to-be-cooled material continuing to be cooled to freeze, wherein the preset temperature is not lower than 0 degree; if no, the step of obtaining the temperature in the storage container is returned until the temperature in the storage container 302 reaches the preset temperature.

[0053] As shown in FIG. 6, when the ice-making mode ends, the second valve 23 is opened, the third valve 31 connecting the outlet side of the ice-making evaporator 11 and the inlet side of the refrigeration evaporator 21 is opened, and the fourth valve 14 is closed, so that the refrigerant flowing out of the ice-making evaporator 11 enters the refrigeration evaporator 21 again. At this time, the first capillary 12 and the ice-making evaporator 11 in the first refrigeration circuit 10 are in parallel connection with the second capillary 22 in the second refrigeration circuit 20, and the ice-making evaporator 11 and the refrigeration evaporator 21 are in series connection. Figures 4 to 6

[0054] A part of the refrigerant flowing out of the ice-making evaporator 11 enters the refrigeration evaporator 21 through the third valve 31 to continue to supply cold to the ice bucket 301 and / or the storage container 302 to store ice or cold drink, and can also supply cold to the refrigeration compartment 2.

[0055] After the ice-making mode ends, the flow direction of the refrigerant is controlled to make the refrigeration equipment consider both the storage of ice and the refrigeration of the refrigeration compartment 2, and the refrigerant flowing out of the ice-making evaporator 11 enters the refrigeration evaporator 21 again, so that the cold of the refrigerant is fully utilized to supply cold to the refrigeration compartment 2, the refrigeration efficiency is improved, and the energy consumption is reduced.

[0056] After the ice-making mode ends, it is obtained whether there is ice in the ice bucket 301, if yes, the first valve 13 and the third valve 31 are kept in the opened state to maintain the supply of cold to the ice bucket 301; if no, the first valve 13 and the third valve 31 are closed, the refrigerant no longer flows through the ice-making evaporator 11 to supply cold to the ice bucket 301, and the normal refrigeration mode of the refrigeration equipment is restored, and the refrigerant only flows through the refrigeration evaporator 21 to supply cold to the refrigeration compartment 2.

[0057] After the ice-making mode ends, it is obtained whether there is to-be-cooled material in the storage container 302, if yes, the first valve 13 and the third valve 31 are kept in the opened state to maintain the supply of cold to the storage container 302; if no, the first valve 13 and the third valve 31 are closed, the refrigerant no longer flows through the ice-making evaporator 11 to supply cold to the storage container 302, and the normal refrigeration state of the refrigeration equipment is restored, and the refrigerant only flows through the refrigeration evaporator 21 to supply cold to the refrigeration compartment 2.​

[0058] In the ice-making mode of the present application, the ice-making evaporator 11 supplies cold to the ice bucket 301 and / or the liquid storage container 302, and the end of the ice-making mode is marked by the ice in the ice bucket 301 being made and / or the contents of the liquid storage container 302 reaching the preset temperature.

[0059] The control method of the refrigeration device of the present application changes the length of time for which the refrigeration compartment 2 stops supplying cold by controlling the temperature at which the refrigeration compartment 2 is turned on, to control the demand for refrigeration by the refrigeration compartment 2, to ensure that ice-making proceeds smoothly and to improve the user experience.

[0060] It should be understood that although the present specification is described in terms of examples, not every example contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each example can also be appropriately combined to form other examples that those skilled in the art can understand.

[0061] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present application and are not intended to limit the protection scope of the present application, and any equivalent embodiments or changes made without departing from the spirit of the present application should be included in the protection scope of the present application.
