Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular, to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and is also a civilian product that keeps food or other items in a constant low temperature state.

[0003] In the related art, a refrigerator includes a water supply pipe, a water injection pipe, and an ice maker. The water supply pipe is connected to a water source and is connected to the water injection pipe. The water injection pipe is connected to the ice maker, and the water from the water source enters the ice maker through the water supply pipe and the water injection pipe.

[0004] However, the water is likely to splash when flowing to the ice maker. Summary of the Utility Model

[0005] The embodiments of the present application provide a refrigerator in which water is not likely to splash when flowing to the ice maker.

[0006] In a first aspect, the embodiments of the present application provide a refrigerator, including:

[0007] A connector, which includes a first connection part and a second connection part connected to each other. The axis of the first connection part has an included angle with the axis of the second connection part. The first connection part is configured with an installation cavity and a first inner cavity arranged along the axis, and the installation cavity and the first inner cavity are in communication with each other. The second connection part is configured with a second inner cavity, and the second inner cavity is in communication with the middle area of the first inner cavity along the extension direction;

[0008] A water supply pipe, which is in communication with the installation cavity and is configured to be in communication with a water source;

[0009] A water injection pipe, which is in communication with the second inner cavity;

[0010] An ice maker, which is in communication with the water injection pipe;

[0011] The diameter of the first inner cavity is smaller than the diameter of the second inner cavity. Along the axis of the second connection part, from the side close to the first inner cavity to the side far from the first inner cavity, the diameter of the second inner cavity gradually increases.

[0012] In this way, the water in the water source enters the first inner cavity through the water supply pipe, impacts the inner wall of the first inner cavity and then flows reversely, and then flows to the ice maker through the second inner cavity and the water injection pipe. Among them, the impact of the water on the inner wall of the first inner cavity can play a role in reducing the speed. Moreover, the diameter of the first inner cavity is smaller than the diameter of the second inner cavity, and along the water flow direction, the diameter of the second inner cavity gradually increases, so that the speed can be reduced. Therefore, the water flow speed in the water injection pipe in the present application is relatively low, and splashing can be effectively avoided.

[0013] In some embodiments of the present application, a box body is further included, the connector is embedded in the back of the box body, the water supply pipe is located outside the box body, and the angle between the axial direction of the first connecting part and the axial direction of the second connecting part is 70-110 degrees.

[0014] In this way, the installation of the water supply pipe is utilized, and the packaging and transportation of the refrigerator are facilitated.

[0015] In some embodiments of the present application, the angle between the axial direction of the first connecting portion and the axial direction of the second connecting portion is 90 degrees.

[0016] In this way, when the water flows, the turning angle is larger and the deceleration effect is better.

[0017] In some embodiments of the present application, a distance between an inner wall of the second inner cavity facing away from the installation cavity and an inner wall of the first inner cavity facing away from the installation cavity is not less than 5 mm.

[0018] This is helpful to ensure the impact area of the water flow and to reduce the water flow speed.

[0019] In some embodiments of the present application, the water injection pipe is configured with a connection opening, the connection opening is spaced apart from the end of the water injection pipe, and an outer wall of the second connection portion is configured with an elastic connection portion;

[0020] The water injection pipe is sleeved on the outer wall of the second connecting part, and the elastic connecting part is inserted into the connecting opening.

[0021] In this way, the water injection pipe can be effectively prevented from falling off.

[0022] In some embodiments of the present application, a positioning opening is configured at the end of the water injection pipe, and a positioning structure is configured on the outer wall of the second connecting portion;

[0023] The water injection pipe is sleeved on the outer wall of the second connecting part, and the positioning structure is inserted into the positioning opening.

[0024] This facilitates installation and helps ensure that the elastic connecting part is inserted into the connecting opening more quickly.

[0025] In some embodiments of the present application, a first sealing structure is further included, the outer wall of the second connecting portion is provided with an accommodating cavity, and the first sealing structure is located in the accommodating cavity;

[0026] The water injection pipe is sleeved on the outer wall of the second connecting part, and the first sealing structure abuts against the inner wall of the water injection pipe.

[0027] In this way, water leakage can be effectively avoided.

[0028] In some embodiments of the present application, a second sealing structure is further included. The second sealing structure is sleeved on the water supply pipe, the water supply pipe is inserted into the installation cavity, and the second sealing structure abuts against the inner wall of the installation cavity.

[0029] In this way, water leakage can be effectively avoided.

[0030] In some embodiments of the present application, a locking member is further included. The locking member is sleeved on the water supply pipe, and the locking member abuts against the inner wall of the installation cavity.

[0031] The locking member is located on the side of the second sealing structure away from the first inner cavity.

[0032] In this way, the water supply pipe can be effectively prevented from falling off.

[0033] In a second aspect, an embodiment of the present application provides a refrigerator, including:

[0034] A connector, which includes a first connection part and a second connection part connected to each other. The axis of the first connection part has an included angle with the axis of the first connection part. The second inner cavity of the second connection part communicates with the middle area of the first inner cavity of the first connection part. The diameter of the first inner cavity is smaller than the diameter of the second inner cavity. Along the axis of the second connection part, from the side close to the first inner cavity to the side far from the first inner cavity, the diameter of the second inner cavity gradually increases;

[0035] Water is configured to flow to the ice maker through the water supply pipe, the first inner cavity, the second inner cavity and the water injection pipe.

[0036] In this way, the water in the water source enters the first inner cavity through the water supply pipe, impacts the inner wall of the first inner cavity and then flows reversely, and then flows to the ice maker through the second inner cavity and the water injection pipe. Among them, the impact of water on the inner wall of the first inner cavity can play a role in reducing the speed. Moreover, the diameter of the first inner cavity is smaller than the diameter of the second inner cavity, and along the water flow direction, the diameter of the second inner cavity gradually increases, so that the speed can be reduced. Therefore, the water flow speed in the water injection pipe in the present application is relatively low, and splashing can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] As described in the background art, the water from the water source enters the ice maker through the water supply pipe and the water injection pipe, and there is no water interception measure in the water circuit. When the water pressure is relatively high, the ice maker often splashes water.

[0071] To solve the above technical problems, in the refrigerator provided in the present application, by providing a connector, the connector includes a first connection part and a second connection part that are connected to each other. The axial direction of the first connection part and the axial direction of the second connection part have an included angle. The first connection part is configured with an installation cavity and a first inner cavity arranged axially, and the installation cavity and the first inner cavity communicate with each other. The second connection part is configured with a second inner cavity, and the second inner cavity communicates with the middle area of the first inner cavity along the extension direction. The diameter of the first inner cavity is smaller than the diameter of the second inner cavity. Along the axial direction of the second connection part, from the side close to the first inner cavity to the side far from the first inner cavity, the diameter of the second inner cavity gradually increases. The water in the water source enters the first inner cavity through the water supply pipe, impacts the inner wall of the first inner cavity and then flows reversely, and then flows to the ice maker through the second inner cavity and the water injection pipe. Among them, the water impacting the inner wall of the first inner cavity can play a role in reducing the speed. Moreover, the diameter of the first inner cavity is smaller than the diameter of the second inner cavity, and along the water flow direction, the diameter of the second inner cavity gradually increases, so that the speed can be reduced. Therefore, the water flow speed in the water injection pipe in the present application is relatively low, and external splashing can be effectively avoided.

[0078] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0079] See Figure 1 and Figure 2 As shown, this embodiment provides a refrigerator, including a cabinet 100 and a door body 200.

[0080] Wherein, a refrigerating compartment can be defined inside the cabinet 100.

[0081] The refrigerated compartment can be at least one. When the number of refrigerated compartments is one, the refrigerated compartment can be any one of a refrigerating chamber, a freezing chamber, or a variable temperature chamber. When the number of refrigerated compartments is two or more, the multiple refrigerated compartments can include at least one or more of a refrigerating chamber, a freezing chamber, or a variable temperature chamber.

[0082] Wherein, the door body 200 is pivotally provided on the front side of the cabinet 100 to close and open the refrigerated compartment for taking and placing items in the refrigerated compartment.

[0083] It should be noted that the number of door bodies 200 can be one, two, or more.

[0084] In some embodiments, the refrigerator includes a refrigeration system.

[0085] Wherein, the refrigeration system can include a compressor, a condenser, a throttling device, and an evaporator. The compressor, the condenser, the throttling device, and the evaporator are connected in series through pipelines in sequence, and a refrigerant flows in the pipelines.

[0086] When the compressor operates, the low-temperature and low-pressure refrigerant is sucked into the compressor and compressed into a high-temperature and high-pressure superheated gas in the compressor cylinder and then discharged into the condenser. The high-temperature and high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continuously drops, gradually being cooled into a normal-temperature and high-pressure saturated vapor and further cooled into a saturated liquid. The pressure of the refrigerant remains almost unchanged during the entire condensation process.

[0087] The throttling device can include a decompression pipe or an electronic expansion valve. In this application, the case where the throttling device includes a decompression pipe is taken as an example for description. The decompression pipe has a low cost and is not prone to abnormal failures. The condensed refrigerant saturated liquid is throttled and depressurized through the decompression pipe, and the refrigerant becomes a normal-temperature and low-pressure wet vapor. Then, the normal-temperature and low-pressure wet vapor absorbs heat and vaporizes through the evaporator, not only reducing the temperature of the evaporator and its surroundings, but also turning the refrigerant into a low-temperature and low-pressure gas. The evaporator cools the air in the refrigerated compartment to lower the temperature of the air in the refrigerated compartment.

[0088] The refrigerant coming out of the evaporator returns to the compressor again to repeat the above process, so that the evaporator can continuously cool the air in the refrigerated compartment, and thus the refrigerated compartment can be maintained at a set temperature.

[0089] In some embodiments, the refrigerator includes an ice maker 300 for making ice.

[0090] In some embodiments, the ice maker 300 can be located in the freezing chamber or the ice maker 300 can be located in the refrigerating chamber.

[0091] In some embodiments, the refrigerator includes a water injection pipe 400 for injecting water into the ice tray of the ice maker 300.

[0092] In some embodiments, the refrigerator includes a water supply pipe 500 for connecting to a water source and delivering water flow.

[0093] It should be noted that the water source can be an internal water tank, or an external water tank, a faucet, etc.

[0094] In some embodiments, the number of the water supply pipes 500 can be at least two.

[0095] In some embodiments, the water supply pipe 500 is communicated with a water supply valve 600 for controlling the on / off of the water supply pipe 500.

[0096] See Figures 3 to 7 As shown, in some embodiments, the refrigerator includes a connector 700 for connecting the water supply pipe 500 and the water injection pipe 400.

[0097] In some embodiments, the connector 700 includes a first connecting portion 710 and a second connecting portion 720 which are connected to each other. The axis of the first connecting portion 710 has an included angle with the axis of the second connecting portion 720.

[0098] Wherein, the first connecting portion 710 is configured with a first inner cavity 711.

[0099] Wherein, the second connecting portion 720 is configured with a second inner cavity 721.

[0100] In some embodiments, the first connecting portion 710 is configured with an installation cavity 712 and a first inner cavity 711 arranged axially, and the installation cavity 712 and the first inner cavity 711 are communicated with each other.

[0101] Wherein, the water supply pipe 500 is communicated with the installation cavity 712. The water injection pipe 400 is communicated with the second inner cavity 721. The ice maker 300 is communicated with the water injection pipe 400. The water from the water source flows through the water supply pipe 500, the first inner cavity 711, the second inner cavity 721 and the water injection pipe 400 into the ice maker 300.

[0102] It should be noted that for the sake of simplified representation Figure 2 and Figure 3 the water injection pipe 400 is not connected to the second connecting portion 720 in Figure 5 shown. The actual state can be seen in

[0103] See Figure 7 As shown, specifically, the axis of the installation cavity 712 and the axis of the first inner cavity 711 can coincide with the axis of the first connecting portion 710. The axis of the second inner cavity 721 can coincide with the axis of the second connecting portion 720.

[0104] In some embodiments, the second inner cavity 721 communicates with an intermediate region of the first inner cavity 711 in the extending direction. That is to say, the communication port for entering the second inner cavity 721 from the first inner cavity 711 is located in the intermediate region of the first inner cavity 711, and there is a space for water flow in front of and behind the communication port along the flowing direction of the water in the first inner cavity 711.

[0105] In this way, when water flows, it will hit the inner wall of the first inner cavity 711 and then flow reversely into the second inner cavity 721. Due to the action of the external water pressure, the pressure of the water flow in the first inner cavity 711 is relatively large, and it is in a turbulent state at the end of the first inner cavity 711. The end of the first inner cavity 711 can intercept the water flow, which is beneficial to reducing the flow rate of the water flow and effectively avoiding the water from splashing when flowing to the ice maker 300 at a relatively high speed.

[0106] See Figure 7 As shown, in some embodiments, the diameter D3 of the first inner cavity 711 is smaller than the diameter of the second inner cavity 721. Along the axial direction of the second connecting portion 720, from the side close to the first inner cavity 711 to the side far from the first inner cavity 711, the diameter of the second inner cavity 721 gradually increases. That is to say, D1 is smaller than D2. In this way, during the process of water flow, it is beneficial to gradually reduce the water speed and effectively avoid the water from splashing when flowing to the ice maker 300 at a relatively high speed.

[0107] See Figure 2 and Figure 8 As shown, in some embodiments of the present application, the connector 700 is embedded in the back of the box body 100. In this way, it is beneficial to the aesthetics of the refrigerator.

[0108] Among them, the water supply pipe 500 is located outside the box body 100. In this way, it is beneficial to the maintenance of water path devices such as the water supply pipe 500.

[0109] See Figure 7 As shown, in some embodiments, the included angle between the axial direction of the first connecting portion 710 and the axial direction of the second connecting portion 720 is 70 - 110 degrees.

[0110] It can be understood that when the position of the ice maker 300 in the box body 100 is fixed, in order to install it, the position of the water injection pipe 400 needs to be fixed, so the position of the second connecting portion 720 is fixed. Therefore, when the included angle between the axial direction of the first connecting portion 710 and the axial direction of the second connecting portion 720 is less than 70 degrees, the gap between the first connecting portion 710 and the outer shell of the box body 100 is relatively small, which is not conducive to the installation of the water supply pipe 500.

[0111] When the angle between the axial direction of the first connection part 710 and the axial direction of the second connection part 720 is greater than 110 degrees, the gap between the first connection part 710 and the outer shell of the box body 100 is large. After the water supply pipe 500 is connected to the first connection part 710, the distance between the water injection pipe 400 and the box body 100 at the connection position is likely to be large, which is not conducive to packaging and transportation.

[0112] It should be noted that, for the sake of overall aesthetics and convenience in packaging and transportation of the refrigerator, the water injection pipe 400 should fit the rear wall of the box body 100 as closely as possible.

[0113] In some embodiments of the present application, in order to improve the deceleration effect of the water flow, the angle between the axial direction of the first connection part 710 and the axial direction of the second connection part 720 is 90 degrees. In this way, when the water flow flows, the turning angle is larger and the deceleration effect is better.

[0114] See also Figure 7 As shown, in some embodiments of the present application, the distance H between the inner wall of the second inner cavity 721 facing away from the installation cavity 712 and the inner wall of the first inner cavity 711 facing away from the installation cavity 712 is not less than 5 mm. This is conducive to ensuring the impact area of the water flow and reducing the water flow speed.

[0115] In some embodiments, a distance H between an inner wall of the second inner cavity 721 facing away from the installation cavity 712 and an inner wall of the first inner cavity 711 facing away from the installation cavity 712 may be 10 mm or 15 mm.

[0116] Alternatively, in some embodiments, the distance H between the inner wall of the second inner cavity 721 facing away from the installation cavity 712 and the inner wall of the first inner cavity 711 facing away from the installation cavity 712 may be not less than 20 mm, for example, 25 mm or 30 mm.

[0117] In some embodiments, the water injection pipe 400 is sleeved on the outer wall of the second connection part 720. In this way, compared with the water injection pipe 400 inserted into the second connection part 720, the water injection pipe 400 is sleeved on the outer wall of the second connection part 720, and water is not easy to accumulate between the water injection pipe 400 and the second connection part 720.

[0118] It is understandable that when the ice maker 300 is placed in the freezing chamber, the water between the water injection pipe 400 and the second connection portion 720 is easily frozen.

[0119] See also Figure 4 and Figure 9 As shown, in some embodiments of the present application, in order to facilitate the installation of the water injection pipe 400 and prevent the water injection pipe 400 from falling off, the water injection pipe 400 is configured with a connection opening 410. The connection opening 410 may be spaced apart from the end of the water injection pipe 400.

[0120] An outer wall of the second connecting portion 720 is configured with an elastic connecting portion 730 .

[0121] When the water injection pipe 400 is sleeved on the outer wall of the second connection part 720, the elastic connection part 730 can be elastically deformed under the action of the inner wall of the second connection part 720. When the elastic connection part 730 is opposite to the connection opening 410, the elastic connection part 730 is reset and inserted into the connection opening 410. In this way, the operation is convenient and the installation efficiency is high.

[0122] In some embodiments, the connection opening 410 may be formed in a rectangular, circular or irregular shape.

[0123] In some embodiments, the elastic connection portion 730 may be an elastic claw or an elastic protrusion.

[0124] In some embodiments of the present application, the end of the water injection pipe 400 is configured with a positioning opening 420, and the outer wall of the second connection part 720 is configured with a positioning structure 740. The water injection pipe 400 is sleeved on the outer wall of the second connection part 720, and the positioning structure 740 is inserted into the positioning opening 420. In this way, it is easy to install and helps to ensure that the elastic connection part 730 is inserted into the connection opening 410 more quickly.

[0125] Exemplarily, the positioning structure 740 may be a positioning protrusion.

[0126] See also Figure 5 As shown, in some embodiments, the end of the water injection pipe 400 facing away from the connector 700 has a flow guide structure 430 .

[0127] The positioning opening 420 and the positioning structure 740 cooperate with each other to play a positioning role, so that the guide structure 430 at the end of the water injection pipe 400 can be located at the correct position.

[0128] See also Figure 9 As shown, in some embodiments of the present application, in order to effectively prevent water leakage, the refrigerator also includes a first sealing structure 800 , and the outer wall of the second connecting part 720 is provided with a accommodating cavity 722 , and the first sealing structure 800 is located in the accommodating cavity 722 .

[0129] The water injection pipe 400 is sleeved on the outer wall of the second connecting portion 720 , and the first sealing structure 800 abuts against the inner wall of the water injection pipe 400 .

[0130] The first sealing structure 800 may be in a compressed state.

[0131] Specifically, the first sealing structure 800 may be a sealing ring, for example, an O-ring.

[0132] See also Figure 10As shown, in some embodiments of the present application, in order to effectively prevent water leakage, a second sealing structure 900 is also included. The second sealing structure 900 is sleeved on the water supply pipe 500, and the water supply pipe 500 is inserted into the installation cavity 712. The second sealing structure 900 abuts against the inner wall of the installation cavity 712.

[0133] The second sealing structure 900 may be in a compressed state.

[0134] Specifically, the second sealing structure 900 may be a sealing ring, for example, an O-ring.

[0135] In some embodiments of the present application, in order to effectively prevent the water supply pipe 500 from falling off, a locking member 1000 is further included, which is sleeved on the water supply pipe 500 and abuts against the inner wall of the installation cavity 712. The locking member 1000 is located on the side of the second sealing structure 900 away from the first inner cavity 711.

[0136] It should be noted that the locking member 1000 may be a locking device commonly used in the related art, and will not be described in detail in this embodiment.

[0137] In some embodiments, the water supply pipe 500 may be sleeved on the outer wall of the first connecting portion 710 .

[0138] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
