Description

Technical Field

[0001] The present application relates to the field of ice making machines, and in particular to an ice making device and a refrigerator. Background Art

[0002] In order to enrich the functions of refrigerators, manufacturers use the freezing layer of air conditioners to form an ice-making module, which can provide users with the function of ice making and broaden the application scenarios of refrigerators.

[0003] In the related art, in order to save space, common refrigerators often have a single ice-making module, and the size and capacity of the ice cubes produced are relatively fixed. For some narrow-mouthed capacity cups, it is difficult to directly put the ice cubes in, which is not conducive to improving the user experience. At the same time, only one type of ice cube can be produced each time, and the production quantity is limited, which is not conducive to meeting user needs. Summary of the invention

[0004] The present application provides an ice-making device and a refrigerator. The ice-making device in the present application is conducive to making ice cubes of different sizes, improving the user experience. At the same time, by controlling the air volume, the making time of large-capacity ice cubes is increased to increase the ice-making speed of large ice cubes, while the making time of small-capacity ice cubes is slowed down, allowing the small ice cubes to be fully cooled, thereby improving the making quality of small-capacity ice cubes.

[0005] The technical solution is as follows:

[0006] According to a first aspect of an embodiment of the present application, an ice-making device is provided, comprising: a refrigeration system, a conveying air duct, an ice-making component, and a liquid injection component; wherein:

The delivery air duct includes at least a first air delivery duct and a second air delivery duct. The ice-making component includes a first ice tray and a second ice tray. The first ice tray is connected to the first air delivery duct. The second ice tray is connected to the second air delivery duct. The liquid injection component is connected to the ice-making component to deliver the liquid to be frozen to the first ice tray and the second ice tray. The cold capacity of the first air delivery duct is greater than the cold capacity of the second air delivery duct. The capacity of the first ice tray is greater than the capacity of the second ice tray.

[0008] The technical solution provided by the embodiments of the present application may have the following beneficial effects:

[0009] The capacity of the first ice tray is greater than that of the second ice tray, so that the capacity of ice cubes produced by the first ice tray is greater than that of the second ice tray. To achieve the same freezing effect per unit time, the cooling capacity required by the first ice tray needs to be greater than that required by the second ice tray. In this way, the differential cooling capacity of the first air duct and the second air duct is coordinated to facilitate rapid cooling of the first ice tray and improve the cooling effect.

DETAILED DESCRIPTION

[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0036] In the related art, a refrigerator with an ice-making module can usually only make ice cubes of a single size, which is not suitable for a variety of application scenarios and is not conducive to optimizing the user experience.

[0037] like Figures 1 to 4 As shown, the present application provides a refrigerator 1, including a cabinet device 10, a compressor 20, a condenser 30, an evaporator 40 and an expansion valve 50. The cabinet device 10 includes a cabinet assembly 11, a freezing chamber 13, a refrigerating chamber 14 and a cabinet door assembly 12. The freezing chamber 13 and the refrigerating chamber 14 are respectively arranged in the cabinet assembly 11. The cabinet door assembly 12 includes a first cabinet door 12a and a second cabinet door 12b. The first cabinet door 12a is rotatably connected to the cabinet assembly 11 to open or close the freezing chamber 13. The second cabinet door 12b is rotatably connected to the cabinet assembly 11 to open or close the freezing chamber 13. The compressor 20, the condenser 30, the evaporator 40 and the expansion valve 50 are respectively arranged in the cabinet assembly 11, and at least part of the evaporator 40 is arranged in the freezing chamber 13.

[0038] like Figure 3As shown, the refrigerator 1 further includes an ice-making device 60, which is installed in the box assembly 11. The ice-making device 60 includes: an ice-making component 100, a liquid injection component 200, a refrigeration system 300 and a conveying air duct 400.

[0039] See you later Figure 2 and Figure 3 As shown, a conveying air duct 400 is provided between the refrigerating compartment 14 and the freezing compartment 13, so as to facilitate conveying part of the cold air from the freezing compartment 13 to the refrigerating compartment 14 through the conveying air duct 400, so as to reduce or maintain the low temperature environment of the refrigerating compartment 14 (for example, 2°C to 8°C).

[0040] The refrigeration system 300 is used to produce cold. The delivery air duct 400 is connected to the refrigeration system 300 so that the delivery air duct 400 delivers cold. Figure 5 As shown, the air delivery duct 400 includes at least a first air delivery duct 410 and a second air delivery duct 420. The ice making component 100 includes a first ice tray 111 and a second ice tray 112. The first ice tray 111 is connected to the first air delivery duct 410 (see the attached drawing for the air flow direction of the cold air). Figure 3 The second ice tray 112 is connected to the second air delivery duct 420. The liquid injection component 200 is connected to the ice making component 100 to deliver the liquid to be frozen to the first ice tray 111 and the second ice tray 112. The cold air volume of the first air delivery duct 410 is greater than the cold air volume of the second air delivery duct 420. The capacity of the first ice tray 111 is greater than the capacity of the second ice tray 112.

[0041] Understandably, see you later. Figure 3 As shown, the compressor 20, the condenser 30, the evaporator 40 and the expansion valve 50 are combined to form a refrigeration system 300. When the refrigerator 1 is in operation, the compressor 20 outputs a high-temperature and high-pressure gaseous refrigerant to the condenser 30, and the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure refrigerant through the condenser 30. The medium-temperature and high-pressure refrigerant passes through the expansion throttling effect of the expansion valve 50, so that the pressure and temperature of the refrigerant are further reduced, and the low-temperature and low-pressure liquid refrigerant flows out of the expansion valve 50 to the evaporator 40. The low-temperature and low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 40. At least part of the evaporator 40 is arranged in the freezing chamber 13, so that the refrigerant absorbs a large amount of heat in the freezing chamber 13 during the evaporation process, thereby reducing the temperature in the freezing chamber 13, making it easier to use the freezing chamber 13 to freeze items and realize the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 40 is replenished back to the compressor 20 to form a refrigerant circuit. In this way, the refrigerant circulates continuously in the refrigerant circuit to maintain the freezing environment of the freezing chamber 13 (for example, less than -1°C).

[0042] See attached Figure 5As shown, after the refrigeration system 300 produces cold air, it is transported to the first ice tray 111 and the second ice tray 112 through the first air duct 410 and the second air duct 420 respectively, wherein the cold air volume of the first air duct 410 is greater than the cold air volume of the second air duct 420, and the capacity of the first ice tray 111 is greater than the capacity of the second ice tray 112, so that the capacity of ice cubes produced by the first ice tray 111 is greater than the capacity of the second ice tray 112. If the same freezing effect is to be achieved per unit time, the cold air required by the first ice tray 111 needs to be greater than the cold air required by the second ice tray 112. In this way, the difference in cold air between the first air duct 410 and the second air duct 420 is conducive to achieving rapid refrigeration of the first ice tray 111 and improving the refrigeration effect. Furthermore, the differentiated distribution of cold air can slow down the ice making speed of the second ice tray 112, facilitate the full freezing and ice formation of the second ice tray 112, and thus improve the ice making effect.

[0043] like Figure 2 As shown, in some embodiments, along the height direction of the refrigerator 1, the freezing chamber 13 is arranged below the refrigerating chamber 14. The refrigerator 1 also includes a first fan (not marked) arranged in the box assembly 11. The air inlet end or the air outlet end of the first fan is connected to the air duct, and is used to transport part of the cold air in the freezing chamber 13 to the refrigerating chamber 14.

[0044] It should be noted that the first ice tray 111 and the second ice tray 112 can be formed by a single ice tray or multiple ice trays, and no excessive restrictions are imposed here. At the same time, the ice capacity of the first ice tray 111 is greater than that of the second ice tray 112, which can be reflected in the difference in the total number of single ice cubes of the same size (i.e., the number of ice cubes produced by the first ice tray 111 is greater than that of the second ice tray 112), or the same number of ice cubes but different sizes (i.e., the size of ice cubes produced by the first ice tray 111 is greater than that of ice cubes produced by the second ice tray 112), etc.

[0045] In some embodiments, see the attached Figure 3 As shown, the first ice tray 111 and the second ice tray 112 include a plurality of small ice cubes spaced apart from each other, wherein the size of the small ice cubes of the first ice tray 111 is larger than the size of the small ice cubes of the second ice tray 112, so that the first ice tray 111 forms large ice cubes and the second ice tray 112 forms small ice cubes.

[0046] It should be noted that the cold air volume of the first air duct 410 and the second air duct 420 can be adjusted by controlling the flow of the ducts through a control valve, or by achieving air volume control through structural improvements.

[0047] Specifically, in a specific implementation mode, see Figure 5 Shown and see Figure 6As shown, the refrigeration system 300 includes a refrigeration device 310, and a first air outlet and a second air outlet arranged on the refrigeration device 310. The first air outlet is connected to the first air duct 410 so that the cold air is connected to the first ice tray 111 through the first air outlet. The second air outlet is connected to the second air duct 420 so that the cold air is connected to the second ice tray 112 through the second air outlet. Among them, the cross-sectional area of ​​the first air outlet is greater than the cross-sectional area of ​​the second air outlet. In this way, the cold air volume of the first air duct 410 and the second air duct 420 can be reduced by changing the cross-sectional areas of the first air outlet and the second air outlet. The structure is simple and convenient to set up, which is conducive to improving processing efficiency. And further, compared with control through a control valve, the control is more stable through the area difference improvement on a simple structure, and the power consumption is reduced, which is conducive to energy saving.

[0048] In another specific embodiment, the refrigeration system 300 includes two refrigeration devices 310, which are respectively a first refrigeration device connected to the first air delivery duct 410 and a second refrigeration device connected to the second air delivery duct. The cold air volume of the first air delivery duct 410 and the second air delivery duct 420 is differentially controlled by the refrigeration difference between the first refrigeration device and the second refrigeration device. In this way, it is beneficial to ensure the wind speed stability of the output air volume, improve the adequacy of heat exchange, and improve the quality of ice making.

[0049] In combination with any of the above-mentioned embodiments of the ice-making component 100, in order to improve the quality of ice making, as Figure 7 As shown, the ice making component 100 also includes at least one group of bearing components 140. The first ice tray 111 includes a first ice tray 111 body and at least one first opening provided in the first ice tray 111 body. The second ice tray 112 includes a second ice tray 112 body and at least one second opening provided in the second ice tray 112 body. The at least one group of bearing components 140 includes a first bearing component 140 covering the first opening and a second bearing component 140 covering the second opening. In this way, the first air duct 410 and the second air duct 420 can reduce the contamination of ice cubes in the first ice tray 111 and the second ice tray 112, thereby improving the cleanliness performance of ice making.

[0050] Further, in a specific embodiment, see Figure 7 As shown, and Figure 8As shown, the first air duct 410 is connected to the first ice tray 111 through the first bearing assembly 140. The second air duct 420 is connected to the second ice tray 112 through the second bearing assembly 140. It should be noted that the first bearing assembly 140 and the first air duct 410 can be matched in a manner that is not limited to plug-in, but can also be sleeved or welded, etc., which will not be described in detail here. In this way, the air duct is matched by the bearing assembly 140 and the first ice tray 111 or the second ice tray 112, which is simple in design and convenient for processing.

[0051] In addition, see attached Figure 5 As shown, the ice-making component 100 also includes at least one group of snap-fit ​​components 150. At least one group of snap-fit ​​components 150 includes a first snap-fit ​​component 151 fixedly connected to the first ice tray 111 and a second snap-fit ​​component 152 fixedly connected to the second ice tray 112. The first ice tray 111 is snap-fitted and connected to the first bearing component 140 through the first snap-fit ​​component 151. The second ice tray 112 is snap-fitted and connected to the second bearing component 140 through the second snap-fit ​​component 152. The first ice tray 111 is snap-fitted and connected to the first bearing component 140 through the first snap-fit ​​component 151. The second ice tray 112 is snap-fitted and connected to the second bearing component 140 through the second snap-fit ​​component 152. In this way, the snap-fitting connection between the first ice tray 111 and the second ice tray 112 and the bearing component 140 is realized through the snap-fit ​​component 150, which improves the fixing effect and facilitates disassembly.

[0052] In one example, the clamping assembly 150 includes a clamping arm, and the bearing assembly 140 is provided with a slot, and one end of the clamping arm is clamped with the slot to achieve fixation. In this way, the design of the clamping arm is simple, and the space occupied is small, which is conducive to improving space utilization.

[0053] In order to improve the ice receiving effect, in some embodiments, Figure 7 and Figure 8As shown, the ice making component 100 also includes at least one group of ice storage containers 130 and at least one group of connecting components 160. The at least one group of ice storage containers 130 includes a first ice storage container 130 and a second ice storage container 130. The at least one group of connecting components 160 includes a first connecting component 160 and a second connecting component 160. The first ice storage container 130 is detachably connected to the first ice tray 111 through the first connecting component 160. The second ice storage container 130 is detachably connected to the second ice tray 112 through the second connecting component 160. Among them, the first connecting component 160 is fixedly connected to the first snap-fit ​​component 151. The second connecting component 160 is fixedly connected to the second snap-fit ​​component 152. It can be understood that the ice storage container 130 can store ice cubes that fall from the ice tray, and the arrangement of the first ice storage container 130 and the second ice storage container 130 can classify ice cubes for user selection. At the same time, by arranging the connecting assembly 160 between the ice storage container 130 and the locking assembly 150, the ice storage container 130 can be fixed to the first ice tray 111 and the second ice tray 112, and the supporting assembly 140, and can be detachably connected to facilitate the extraction of ice cubes.

[0054] It should be noted that the connection method between the connection component 160 and the first ice tray 111 and the second ice tray 112 can be plug-in, snap-on, magnetic, etc., and no excessive restrictions are imposed herein.

[0055] In order to improve the effect of heat exchange ice making, in a specific embodiment, see Fig. 9 As shown, at least one of the first bearing assembly 140 and the second bearing assembly 140 is provided with an air guide baffle 143, so that at least part of the cold air flows to the first ice tray 111 and / or the second ice tray 112 through the air guide baffle 143. Specifically, the air guide baffle 143 can be bent and connected to the first bearing assembly 140 or the second bearing assembly 140. In this way, the cold air can be guided to the surface of the first ice tray 111 and / or the second ice tray 112 through the air guide baffle 143, thereby accelerating the freezing speed of the liquid to be frozen in the first ice tray 111 and / or the second ice tray 112 and improving the ice making efficiency.

[0056] Further, in another specific embodiment, see Fig. 9 As shown, at least one of the first bearing assembly 140 and the second bearing assembly 140 may also be provided with a liquid guide 144, and the liquid guide 144 is fixedly connected to the wind guide baffle 143, so that the liquid droplets on the first bearing assembly 140 and / or the second bearing assembly 140 can enter the first ice tray 111 and / or the second ice tray 112 along the liquid guide 144. It can be understood that when the cold air encounters the temperature side with a temperature difference, it is easy to liquefy and condense in the air duct to interfere with the cold air, and the liquid guide 144 can be provided to guide the liquefied liquid droplets to the first ice tray 111 or the second ice tray 112.

[0057] It should be noted that the liquid guide member 144 and the wind guide baffle 143 can be manufactured separately and fixedly connected by welding, bonding, etc., or they can be manufactured as one piece, and no further limitation is given here.

[0058] In some embodiments, Figure 5 As shown, the liquid injection component 200 includes a liquid injection pipe 220 and a liquid pump 230. The liquid pump 230 is used to provide the liquid to be frozen to the liquid injection pipe 220. The liquid injection component 200 also includes a first liquid injection pipe 220, a second liquid injection pipe 220, a first control valve 223 and a second control valve 224. The first liquid injection pipe 220 is connected and arranged between the liquid pump 230 and the first liquid storage chamber 211. The second liquid injection pipe 220 is connected and arranged between the liquid pump 230 and the second liquid storage chamber 212. The first control valve 223 is arranged on the first liquid injection pipe 220 to adjust the flow rate of the liquid to be frozen from the first liquid injection pipe 220 to the first liquid storage chamber 211. The second control valve 224 is arranged on the second liquid injection pipe 220 to adjust the flow rate of the liquid to be frozen from the second liquid injection pipe 220 to the second liquid storage chamber 212. Thus, different from the on-off control of the liquid pump 230, the control method through the control valve is more stable and avoids the reduction of the operating life caused by multiple on-off controls of the liquid pump 230.

[0059] It should be noted that the liquid guiding member 144 may be, but is not limited to, a liquid guiding baffle, and may also be a protrusion or other structure, and no excessive restrictions are imposed herein.

[0060] In order to further improve the automation level of the ice making device 60, in some embodiments, Figure 5 As shown, the ice making device 60 also includes a control component 240 and a liquid measuring component 250 that are communicatively connected to the first control valve 223 and the second control valve 224. The liquid measuring component 250 is used to measure the volume of the liquid to be frozen in the first liquid storage chamber 211 and the second liquid storage chamber 212. The control component 240 adjusts the first control valve 223 and the second control valve 224 according to the volume of the liquid to be frozen to control the volume of the solution in the first liquid storage chamber 211 and the second liquid storage chamber 212. It can be understood that the volume of the liquid to be frozen in the first liquid storage chamber 211 and the second liquid storage chamber 212 is measured by the liquid measuring component 250, and the control component 240 receives the volume of the liquid to be frozen and compares the volume of the liquid to be frozen with the preset range. When the volume of the liquid to be frozen is less than the preset range, the opening of the first control valve 223 or the second control valve 224 is increased to increase the volume of the liquid to be frozen in the first liquid storage chamber 211 and the second liquid storage chamber 212. When the volume of the to-be-frozen liquid is greater than a preset range, the first control valve 223 or the second control valve 224 is closed.
