DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the present embodiment, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0041] Refrigerators are common household appliances in people's lives, mainly storing food by freezing and refrigerating. With the development of science and technology, people's living standards have gradually improved, the types of refrigerators have become more and more diverse, and the functions of refrigerators have gradually become richer.

[0042] like Figure 1 and Figure 2 As shown, the utility model 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.

[0043] Combination Figure 3 As shown, 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 is further reduced in pressure and temperature by the expansion throttling effect of the expansion valve 50, 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).

[0044] See you later Figure 2 As shown, an air duct 15 is provided between the refrigerating compartment 14 and the freezing compartment 13, so as to transport part of the cold air from the freezing compartment 13 to the refrigerating compartment 14 through the air duct 15, so as to reduce or maintain the low temperature environment of the refrigerating compartment 14 (for example, 2°C to 8°C).

[0045] like Figure 2 As shown, in some embodiments, along the height direction (Z-axis 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 15, which is used to transport part of the cold air from the freezing chamber 13 to the refrigerating chamber 14.

[0046] In some embodiments, the outer wall of the freezing chamber 13 is covered with an insulation layer (not shown) to separate the evaporator 40 from the compressor 20 and the condenser 30. The refrigerator 1 also includes an air-cooling heat dissipation assembly (not shown) disposed on the cabinet assembly 11, which can at least dissipate heat for the condenser 30.

[0047] In some embodiments, the box assembly 11 further includes a fresh-keeping compartment disposed in the box assembly 11 . Along the height direction of the refrigerator 1 , the fresh-keeping compartment is disposed between the refrigerating compartment 14 and the freezing compartment 13 .

[0048] Further, in order to meet the needs of users for using ice cubes, such as Figure 4 As shown, in some embodiments, the refrigerator 1 further includes an ice-making device 60 for making ice cubes. The ice-making device 60 includes an ice-making component 100 and a liquid injection component 200. The ice-making component 100 includes an ice tray 110 disposed in the freezing chamber 13. The liquid injection component 200 is used to inject liquid required for making ice cubes into the ice tray 110.

[0049] like Figure 4 As shown, in one example, the liquid injection component 200 includes a liquid storage container 210 and a liquid injection pipe 220. The liquid storage container 210 is disposed in the refrigerating compartment 14, one end of the liquid injection pipe 220 is connected to the liquid storage container 210, and the other end of the liquid injection pipe 220 is disposed above the ice tray 110 along the height direction of the refrigerator 1.

[0050] Optionally, the liquid injection component 200 further includes a switch valve (not shown), which is disposed on at least one of the liquid storage container 210 and the liquid injection pipe 220, and is used to open the liquid injection component 200 to inject liquid into the ice tray 110, or to close the liquid injection component 200. In addition, in some embodiments, the liquid injection component 200 may further include a water receiving assembly for communicating with the external liquid injection pipe 220.

[0051] like Figure 4 As shown, in some embodiments, the ice tray 110 can be rotatably arranged in the freezing chamber 13, and has a liquid receiving state and an ice pouring state. The ice making component 100 also includes a driving assembly 120 and an ice storage container 130. The driving assembly 120 is arranged in the freezing chamber 13, and is used to drive the ice tray 110 to switch between the liquid receiving state and the ice pouring state. Along the height direction of the refrigerator 1, the ice storage container 130 is arranged below the ice tray 110. In this way, the ice storage container 130 can receive the ice cubes poured from the ice tray 110.

[0052] It should be noted that the ice tray 110 and the driving assembly 120 can be directly or indirectly disposed in the freezing chamber 13 .

[0053] In some embodiments, Figure 4 The first door 12a of the refrigerator is shown to be open and not shown, and the second door 12b is in a closed state. The liquid storage container 210 is arranged on the second door 12b. In this way, the liquid storage container 210 is stored in the cold storage room through the second door 12b, which is convenient for users to take and put the liquid storage container 210. In some embodiments, ice water can also be provided to users.

[0054] Therefore, in addition to the functions of freezing, refrigerating and preserving food, refrigerator 1 can also have the functions of making ice cubes and providing ice water to users, thereby meeting people's usage needs and improving the competitiveness of refrigerator 1 products.

[0055] However, the existing ice maker is usually installed on the left and right side walls of the freezer. This means that the left side of the ice maker near the freezer needs to be connected to the left side wall of the freezer through a connector, and the right side of the ice maker near the freezer needs to be connected to the right side wall of the freezer through a connector. Since the ice maker needs to be connected to both the left and right side walls of the freezer at the same time, the volume of the ice maker needs to be expanded as much as possible along the left and right directions of the freezer 13, which will occupy too much freezing space in the freezer 13, and the volume of the ice maker needs to be infinitely expanded along the left and right directions of the freezer 13, which is inconvenient to use.

[0056] See also Figure 5 and Figure 6 In some embodiments, an ice-making component 100 is provided, including a bearing assembly 140 fixed to the freezing chamber 13. The bearing assembly 140 includes an ice-making casing body 141 and a support frame 142 for hanging the ice-making casing body 141 and fixed to the freezing chamber 13. The ice tray 110 is rotatably arranged on the ice-making casing body 141, and the driving assembly 120 is fixed to the ice-making casing body 141. In this way, the ice tray 110 and the driving assembly 120 are integrated by the bearing assembly 140, so that the ice-making component 100 can be modularly assembled in the freezing chamber 13, which is conducive to improving the assembly efficiency of the refrigerator 1.

[0057] It should be noted that, since the inner shell of the box device 10 of the refrigerator 1 is mostly non-flat, a support frame 142 detachably connected to the ice maker housing body 141 is introduced into the refrigerator 1. On the one hand, the support frame 142 can increase the connection area between the ice maker and the box device 10 and improve the connection stability. On the other hand, the support frame 142 can make the ice maker housing body 141 as horizontal as possible to avoid liquid leakage after the ice tray 110 is filled with water.

[0058] In some embodiments, the ice making part 100 may include a plurality of ice making machines. As an example, when the ice making part 100 includes two ice making machines, the two ice making machines may be arranged side by side. The ice making machine housing bodies 141 of the two ice making machines are detachably arranged on the support frame 142. Among them, any one of the two ice making machine housing bodies 141 can be detachably connected to the support frame 142 independently. Of course, the two ice making machine housing bodies 141 can also be connected as one body and removed from the support frame 142 together. At the same time, according to the ice making needs of the customer, the ice making part 100 may also include an ice making machine housing body 141, or the ice making machine may also be arranged in three or four cases where the size of the freezing space of the freezing chamber 13 allows. Accordingly, the ice making machine housing body 141 is also arranged in three or four cases. In addition, each ice making machine can make ice cubes of different sizes and / or shapes by adjusting the shape and / or size of the ice making grid in the ice tray 110 to meet the diverse needs of customers for ice cubes. Accordingly, in order to facilitate production and processing, the structure and size of each ice-making machine housing body 141 can be set to the same specifications to facilitate mass production, replacement and maintenance.

[0059] See also Figure 7 and Figure 8 In some embodiments, the ice maker housing body 141 is provided with a first connection structure 143, and the support frame 142 is provided with a second connection structure 144. The first connection structure 143 and the second connection structure 144 are detachably connected. Exemplarily, one of the first connection structure 143 and the second connection structure 144 can be a snap-fit ​​member such as a tongue, and the other can be a snap-fit ​​fitting member such as a slot. Of course, the specific forms of the first connection structure 143 and the second connection structure 144 are not limited thereto.

[0060] In other words, the above embodiment installs the ice-making casing body 141 on the top wall 13a of the freezing chamber 13 through the support frame 142 instead of directly connecting the ice-making casing body 141 to the left and right side walls of the freezing chamber 13. Therefore, the volume of the ice-making casing body 141 does not need to be infinitely expanded along the left and right directions of the freezing chamber 13, as long as it is appropriately expanded to meet the user's demand for ice consumption. In this way, it can not only reduce the occupation of the ice-making casing body 141 on the internal freezing space of the freezing chamber 13 of the refrigerator 1, but also facilitate the installation of the ice-making casing body 141 in refrigerators 1 of different models, and has stronger versatility. At the same time, through the detachable connection between the ice-making casing body 141 and the support frame 142, it is also convenient to disassemble the ice-making casing body 141, so as to facilitate its cleaning, maintenance or replacement.

[0061] It should be noted that the support frame 142 mentioned in this article can be a plate-shaped structure, a frame structure, etc. with a certain thickness, and the specific shape is not specifically limited.

[0062] Continue reading Figures 7 and 8In one embodiment, the first connection structure 143 includes a sliding rail 143a and a supporting rail 143b that are spaced apart. The second connection structure 144 includes an inclined section 144a and a horizontal section 144b. Optionally, the inclined section 144a is alternately connected with the horizontal section 144b, and the inclined section 144a gradually tilts upward along the sliding direction of the first connection structure 143 until it is connected to the horizontal section 144b.

[0063] The installation process of the ice-making housing body 141 and the support frame 142 is as follows: first, the initial end of the slide rail 143a is overlapped on the first inclined section 144a, and the ice-making housing body 141 is gradually pushed in the X direction, and the slide rail 143a will contact the horizontal section 144b and the inclined section 144a in turn until it is installed in place. After the first connecting structure 143 and the second connecting structure 144 are slidably matched in place, one side surface of the horizontal section 144b abuts against the slide rail 143a, and the other side surface of the horizontal section 144b abuts against the support rail 143b. In this way, the ice-making housing body 141 and the support frame 142 are pushed in and installed.

[0064] See also Figures 7 and 8 In one embodiment, the ice maker housing body 141 includes a first electrical connector 145, and the support frame 142 includes a second electrical connector 146. When the first connection structure 143 and the second connection structure 144 are slidably matched in place, the plug position of one of the first electrical connector 145 and the second electrical connector 146 corresponds to the jack position of the other. Thus, when the ice maker housing body 141 and the support frame 142 slide in along the X direction, the first electrical connector 145 and the second electrical connector 146 can be plugged in synchronously, thereby improving installation efficiency.

[0065] In the related art, in order to improve the installation stability between the support frame and the ice maker housing body, a locking structure is usually provided between the two. Most of the existing locking structures are implemented by a knob, that is, a knob is provided on the ice maker housing body, a locking part that cooperates with the knob is provided on the support frame, and the support frame and the ice maker housing body are disassembled and locked by turning the knob. However, the structure of the knob and the locking part is complex, the failure rate is high, and there is a risk of missing installation, and the cost is high. At the same time, when the knob and the locking part are locked, the space occupied is large, the volume of the ice maker housing body is increased, the installation space required in the refrigerator is large, and the versatility is poor.

[0066] See also Figures 9 to 11In some embodiments, the support frame 142 is provided with a first limiting portion 1421. The ice maker housing body 141 includes a first housing 141a and a second housing 141b fixed to the first housing 141a and forming a cavity with the first housing 141a. The first housing 141a includes a fixing portion 1411 connected to the second housing 141b, and a second limiting portion 1412 connected to the fixing portion 1411 and buckled with the first limiting portion 1421. Pressing the second limiting portion 1412 drives the second limiting portion 1412 to move along the depth direction 141c of the cavity to achieve separation of the ice maker housing body 141 and the support frame 142.

[0067] It should be noted that the support frame 142 has a first mounting portion and a second mounting portion fixed to the first mounting portion, the first mounting portion is used to connect the support frame 142 to the inner tank of the refrigerator 1, and the second mounting portion is used for the detachable connection between the support frame 142 and the ice maker housing body 141. Optionally, the second mounting portion of the hanging machine faces the ice maker housing body 141, and the first limiting portion 1421 on the support frame 142 is arranged on the second mounting portion.

[0068] The first housing 141a is used to assemble the second limiting portion 1412, so as to realize the detachable connection between the ice-making housing body 141 and the support frame 142 by snapping and separating the first limiting portion 1421 and the second limiting portion 1412. The second housing 141b is used to carry other parts of the ice-making housing body 141, such as the driving assembly 120, the ice tray 110, etc. At the same time, the cavity formed by the ice-making housing body 141 is provided with an air inlet and an air outlet, so that the refrigerator 1 can refrigerate the liquid water carried by the ice tray 110 in the ice-making machine to form ice cubes. In addition, the cavity formed by the ice-making housing body 141 can prevent air or impurities with other flavors in the refrigerator 1 from entering the ice-making housing body 141, so as to avoid affecting the taste and purity of the ice cubes.

[0069] When disassembling the ice-making casing body 141 and the support frame 142, the user only needs to press the second stopper 1412 along the depth direction 141c of the cavity to separate the second stopper 1412 from the first stopper 1421, so that the ice-making casing body 141 and the support frame 142 are unlocked. Afterwards, the user can pull the ice-making casing body 141 in the length direction 141d of the cavity to move, so as to disassemble the ice-making casing body 141 from the support frame 142, and then remove the ice-making casing body 141 from the refrigerator 1. Optionally, the first stopper 1421 and the second stopper 1412 are installed on the side of the ice-making casing body 141 facing the user, so as to facilitate the pressing operation.

[0070] See also Figure 12 to Figure 14In some embodiments, in order to facilitate the processing of the first limiting portion 1421 and the second limiting portion 1412, the first limiting portion 1421 includes at least one locking portion 1421a, and the second limiting portion 1412 includes a pressing portion connected to the fixing portion 1411, and a second limiting portion 1412a fixed to the pressing portion and buckled with the locking portion 1421a. A force is applied to the pressing portion along the depth direction 141c of the cavity to drive the second limiting portion 1412a to separate from the locking portion 1421a. Optionally, one of the locking portion 1421a and the second limiting portion 1412a is a groove, and the other is a protrusion embedded in the groove.

[0071] In some embodiments, to facilitate unlocking the second limiting portion 1412a and the locking portion 1421a, the pressing portion includes a connecting portion 1412b connected to the fixing portion 1411 and having elasticity, and an operating portion 1412c fixed to the connecting portion 1412b, wherein at least a portion of the operating portion 1412c protrudes from the first shell 141a along the length direction 141d of the cavity, and the second limiting portion 1412a is fixed to the connecting portion 1412b.

[0072] That is, the operating portion 1412c and the fixing portion 1411 are elastically connected, so that when the user presses the operating portion 1412c along the depth direction 141c of the cavity, the connecting portion 1412b between the operating portion 1412c and the fixing portion 1411 is elastically deformed, so that the operating portion 1412c can drive the matching relative to the fixing portion 1411 to move along the depth direction 141c of the cavity, so that the second limiting portion 1412a is disengaged from the locking portion 1421a. And, when the user cancels the pressing of the operating portion 1412c, the elastic deformation of the connecting portion 1412b between the operating portion 1412c and the fixing portion 1411 is restored, so that the second limiting portion 1412a can move in the reverse direction of the depth direction 141c of the cavity and then engage with the locking portion 1421a, so as to achieve the locking of the second limiting portion 1412a and the locking portion 1421a.

[0073] Optionally, the connection portion 1412b may be configured to be a metal material or a non-metal material having good elasticity or ductility.

[0074] Meanwhile, when the installation space for the ice maker in the refrigerator 1 allows, the operating portion 1412c can be arranged to protrude from the first shell 141a along the length direction 141d of the cavity, so that the user can apply force to press the operating portion 1412c.

[0075] See also Fig.13 As shown, in some embodiments, in order to increase the force application area of ​​the user on the operating portion 1412c to achieve a labor-saving effect, the operating portion 1412c is configured as an arc structure, and the convex surface of the arc structure faces the wall surface of the first avoidance portion 1413.

[0076] In some embodiments, to facilitate the user to install the ice maker housing body 141 on the support frame 142, the fitting surface between the locking portion 1421a and the second limiting portion 1412a includes a first inclined surface 1417, and the side of the first inclined surface 1417 close to the operating portion 1412c protrudes from the side of the first inclined surface 1417 away from the operating portion 1412c.

[0077] It should be noted that when the user installs the ice-making casing body 141, in order to save operating space, the user pushes the ice-making casing body 141 into the refrigerator 1 along the length direction 141d of the cavity for installation. At this time, the first inclined surface 1417 can guide the matching body so that the matching body and the locking portion 1421a are automatically engaged when the user pushes the ice-making casing body 141.

[0078] In some embodiments, in order to remind the user that the second limiting portion 1412a and the clamping portion are in a buckled state, the connecting portion 1412b is fixedly provided on the wall between the operating portion 1412c and the second limiting portion 1412a, and the support frame 142 is provided with a fourth limiting portion that cooperates with the third limiting portion, so that when the second limiting portion 1412a and the clamping portion 1421a are buckled, the third limiting portion and the fourth limiting portion are pressed. Optionally, the third limiting portion protrudes toward the outside of the cavity, and the third limiting portion includes a second inclined surface 1418, and the side of the second inclined surface 1418 connected to the operating portion 1412c protrudes from the side of the second inclined surface 1418 connected to the second limiting portion 1412a. The fourth limiting portion may be a rib protruding toward the cavity. When the second limiting portion 1412a is engaged with the locking portion 1421a, the rib of the fourth limiting portion presses against the second inclined surface 1418 to prompt the user that the second limiting portion 1412a and the locking portion are already in a locked state.

[0079] In some embodiments, when the second limiting portion 1412a is buckled with the locking portion 1421a, the fourth limiting portion and the third limiting portion can also cooperate to produce a prompt sound to prompt the user that the second limiting portion 1412a and the locking portion are in a buckled state.

[0080] In some embodiments, in order to reduce the volume of the ice maker housing body 141, the second housing 141b includes a first avoidance portion 1413 for accommodating the operating portion 1412c, and there is at least a gap set along the depth direction 141c of the cavity between the wall surface of the first avoidance portion 1413 and the wall surface of the operating portion 1412c. The first avoidance portion 1413 accommodates the operating portion 1412c to reduce the space occupied by the second limit portion 1412 along the length direction 141d of the cavity, thereby reducing the volume of the ice maker housing body 141. And a gap is set between the wall surface of the first avoidance portion 1413 and the wall surface of the operating portion 1412c, which can avoid motion interference. At the same time, in order to avoid assembly errors, a gap can also be set between the first avoidance portion 1413 and the operating portion 1412c along the width direction 141e of the cavity. Optionally, the first avoidance portion 1413 is set as a U-shaped groove.

[0081] See also Fig.13 and Fig.14 As shown, in some embodiments, in order to improve the convenience of users to disassemble the ice maker housing body 141, the second housing 141b includes a first assembly portion 1414 fixed to the first housing 141a, and a second assembly portion 1415 fixed to the first assembly portion 1414 and forming a cavity with the first assembly portion 1414. The first assembly portion 1414 includes a first side portion 1414a and a second side portion 1414b spaced from the first side portion 1414a along the width direction 141e of the cavity, and the first avoidance portion 1413 is provided on the first assembly portion 1414, and the distance from the first avoidance portion 1413 to the first side portion 1414a is greater than the distance from the first avoidance portion 1413 to the second side portion 1414b. The wall surface where the second assembly portion 1415 is connected to the second side portion 1414b is provided with a second avoidance portion 1416.

[0082] Optionally, since the space for installing the ice-making casing body 141 in the refrigerator 1 is limited, in order to save space, the second avoidance portion 1416 is set as a notch, and the second avoidance portion 1416 extends along the length direction 141d of the cavity.

[0083] It should be noted that the second avoidance portion 1416 is arranged on the side of the second shell 141b close to the second side portion 1414b to shorten the distance between the first avoidance portion 1413 and the second avoidance portion 1416, so that the user can achieve one-handed operation when disassembling the ice maker housing body 141, and the distance between the first avoidance portion 1413 and the second avoidance portion 1416 conforms to ergonomic design.

[0084] When the user disassembles the ice-making casing body 141 with one hand, the user inserts four fingers of one hand into the second avoidance portion 1416 and uses the thumb to press the operation portion 1412c to unlock the ice-making casing body 141 and the support frame 142. At the same time, the user bends four fingers to hold the second avoidance portion 1416 and applies force along the length direction 141d of the cavity, so that the ice-making casing body 141 can be disassembled from the support frame 142 with one hand.

[0085] Optionally, in order to enhance the user's gripping comfort, the wall of the notch has a curvature.
