Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] Currently, refrigerators generally use compression refrigeration systems, which provide cooling capacity by controlling the pressure of the refrigerant. These systems typically include solenoid valves, which control parameters such as the refrigerant flow rate and direction, thereby regulating the system's operation.

[0003] In related technologies, a solenoid valve typically includes a housing, a cover, a valve body, and a wiring harness. The cover is fitted onto the housing and forms a receiving cavity with the housing. The front wall of the housing has a first wiring recess, and the front wall of the cover has a second wiring recess corresponding to the first wiring recess. The valve body is housed within the receiving cavity and has multiple first connection terminals extending along the rear wall of the housing towards the front wall of the housing. The wiring harness includes a protective sleeve and multiple connecting wires, each connecting wire having a second connection terminal at its end. The protective sleeve is fitted over the outside of the multiple connecting wires and is spaced apart from the second connection terminals. The second connection terminals are fitted onto the first connection terminals along the rear wall of the housing towards the front wall of the housing.

[0004] However, during the installation of the solenoid valve, the connecting wires located within the interval are prone to damage, which shortens the service life of the solenoid valve and thus reduces the reliability of the refrigeration system. Utility Model Content

[0005] This application provides a refrigerator that solves the technical problem in the related art where the connecting wires located within the interval are easily damaged during the installation of the solenoid valve, shortening the service life of the solenoid valve and thus reducing the reliability of the refrigeration system.

[0006] In a first aspect, embodiments of this application provide a refrigerator, the refrigerator comprising:

[0007] A refrigeration system configured to provide cooling capacity, the refrigeration system comprising:

[0008] Solenoid valve, comprising:

[0009] case;

[0010] A cover body is provided on the housing and together with the housing to form a receiving cavity; at least one of the front wall of the cover body and the front wall of the housing is provided with a wiring recess;

[0011] A valve body, at least partially disposed within the receiving cavity, the valve body having at least one first connection terminal; the first connection terminal extending along a first direction from the front wall of the housing to the rear wall of the housing;

[0012] A wire harness includes a protective sleeve and at least one connecting wire; the at least one connecting wire is correspondingly disposed with at least one first connecting terminal, and each connecting wire has a second connecting terminal at one end; the protective sleeve is sleeved on the outside of the connecting wire and has a gap between it and the second connecting terminal; the second connecting terminal is sleeved on the first connecting terminal in a second direction opposite to the first direction, so that the connecting wire located within the gap is bent and located in the receiving cavity, and the protective sleeve is located in the wiring recess.

[0013] In this embodiment of the refrigerator, when installing the solenoid valve, the second connecting terminal of the wiring harness can be connected to the first connecting terminal of the valve body first, and then the cover can be placed on the housing. In related technologies, the first connecting terminal extends along the rear wall of the housing towards the front wall. In this embodiment, because the first connecting terminal extends along the front wall of the housing towards the rear wall, when the second connecting terminal is connected to the first connecting terminal, the connecting wire within the interval can be bent, and this portion of the connecting wire is located within the receiving cavity, so that the protective sleeve is located within the wiring recess. During the installation of the solenoid valve, the connecting wire within the interval will not contact the front wall of the housing or the front wall of the cover, thereby preventing the connecting wire within the interval from being squeezed by the front wall of the housing and the front wall of the cover, thus preventing damage to the connecting wire within the interval, extending the service life of the solenoid valve, and improving the reliability of the refrigeration system.

[0014] Furthermore, during the installation of the solenoid valve, the assembler only needs to place the protective sleeve inside the wiring recess, eliminating the need to place multiple connecting wires located within the interval inside the wiring recess. This eliminates the need for wire management, improving the solenoid valve's pass-through rate and shortening the installation time, thus increasing the assembly efficiency of the refrigeration system.

[0015] In some embodiments of this application, the valve body includes a coil located within the receiving cavity; the first connecting terminal includes a first connecting end and a second connecting end; the first connecting end is connected to the coil and is close to the front wall of the housing; the second connecting end is farther from the front wall of the housing than the first connecting end; the second connecting terminal includes a third connecting end and a fourth connecting end; the third connecting end is connected to the connecting wire; the fourth connecting end is closer to the front wall of the housing than the third connecting end and is sleeved on the second connecting end.

[0016] With this configuration, since the first connecting end is close to the front wall of the housing and the second connecting end is farther away from the front wall of the housing compared to the first connecting end, the distance between the second connecting end and the rear wall of the housing can be increased, thereby increasing the remaining space inside the housing. When the fourth connecting end of the second connecting terminal is sleeved on the second connecting end, the length of the wire harness located in the receiving cavity can be further extended, thereby preventing the connecting wire located in the interval from contacting the front wall of the housing and the front wall of the cover, and thus preventing the connecting wire located in the interval from being damaged.

[0017] In some embodiments of this application, the front wall of the housing is provided with a first wiring recess, the first wiring recess having a first opening, the first opening being formed at the edge of the front wall of the housing; the front wall of the cover is provided with a second wiring recess, the second wiring recess having a second opening, the second opening being formed at the edge of the front wall of the cover, the second opening being opposite to the first opening.

[0018] With this configuration, after the second connecting terminal is fitted onto the first connecting terminal, a portion of the protective sleeve can be placed within the first wiring recess. Then, when the cover is placed on the housing, the second opening aligns with the first opening, allowing the second wiring recess to fit over another portion of the protective sleeve. This design, combined with the front wall of the housing and the front wall of the cover, simultaneously limits the protective sleeve, improving the stability of the wiring harness and preventing it from being pulled apart, thus enhancing the reliability of the connection between the wiring harness and the valve body.

[0019] In some embodiments of this application, a first protrusion is provided on the side of the front wall of the housing facing away from the receiving cavity; the first wiring recess is provided on the first protrusion and penetrates through the first protrusion.

[0020] This design extends the length of the first wiring recess, increases the contact area between the first wiring recess and the protective sleeve, thereby improving the stability of the wiring harness and further enhancing the reliability of the connection between the wiring harness and the valve body.

[0021] In some embodiments of this application, a second protrusion is provided on the side of the front wall of the cover facing away from the receiving cavity; the second wiring recess is provided on the second protrusion and penetrates through the second protrusion.

[0022] This design extends the length of the second wiring recess, increases the contact area between the second wiring recess and the protective sleeve, thereby improving the stability of the wiring harness and further enhancing the reliability of the connection between the wiring harness and the valve body.

[0023] In some embodiments of this application, the solenoid valve further includes a bendable connecting plate, which connects the rear wall of the cover and the rear wall of the housing; when the connecting plate is in a bent state, the cover is placed on the housing.

[0024] With this design, the rear wall of the cover is connected to the rear wall of the housing via a flexible connecting plate, forming a single integrated structure. During the assembly of the solenoid valve, the assembler does not need to remove or place the cover, improving the assembly efficiency of the solenoid valve and thus increasing the production efficiency of the refrigerator.

[0025] In some embodiments of this application, one of the front wall of the housing facing away from the receiving cavity and the front wall of the cover facing away from the receiving cavity are provided with a first snap-fit ​​portion, and the other is provided with a first snap-fit ​​recess portion, wherein the first snap-fit ​​recess portion and the first snap-fit ​​portion snap-fit ​​each other.

[0026] With this design, the cover and the housing can be connected by the first snap-fit ​​recess and the first snap-fit ​​part, which can improve the convenience of assembling the cover and the housing and improve the assembly efficiency of the solenoid valve.

[0027] In some embodiments of this application, the housing includes a first housing and a second housing. The first housing has a first receiving cavity with a third opening. The second housing has a second receiving cavity with opposing fourth and fifth openings, the fourth opening being connected to the third opening. On opposite sides of the first housing and opposite sides of the second housing, one side is provided with a second engaging portion, and the other side is provided with a second engaging recess, the second engaging recess engaging with the second engaging portion.

[0028] This design, where the first and second housings are connected via interlocking second locking recesses and second locking parts, improves the ease of assembly of the first and second housings and increases the assembly efficiency of the solenoid valve. Furthermore, the interconnecting second locking recesses and second locking parts on opposite sides of the first and second housings prevent gaps between them, thus enhancing the structural reliability of the housings.

[0029] In some embodiments of this application, the refrigerator further includes a cabinet for housing the refrigeration system; a mounting portion is provided on the side edge of the housing facing away from the cover, the mounting portion being used to connect with the cabinet.

[0030] This configuration, by placing the mounting part on the edge of the housing facing away from the cover, allows the housing to be connected to a horizontally arranged plate-like structure within the enclosure, such as the bottom plate of the compressor compartment inside the enclosure. Compared to placing the mounting part on the side wall of the housing and connecting it to a vertically arranged plate-like structure within the enclosure, there is no need to install reinforcing iron on the vertically arranged plate-like structure, thus reducing the material cost of the enclosure.

[0031] Secondly, embodiments of this application provide a refrigerator, the refrigerator comprising:

[0032] A refrigeration system configured to provide cooling capacity, the refrigeration system comprising:

[0033] Solenoid valve, comprising:

[0034] case;

[0035] A cover body is provided on the housing and together with the housing to form a receiving cavity; at least one of the front wall of the cover body and the front wall of the housing is provided with a wiring recess;

[0036] A valve body, at least partially disposed within the receiving cavity, the valve body having at least one first connecting terminal located within the receiving cavity;

[0037] A wire harness includes a protective sleeve and at least one connecting wire, wherein the at least one connecting wire is correspondingly disposed to at least one first connecting terminal, and each connecting wire has a second connecting terminal at its end; the protective sleeve is sleeved on the outside of the connecting wire and is spaced apart from the second connecting terminal;

[0038] Wherein, the first connecting terminal extends along the front wall of the housing toward the rear wall of the housing, so that when the corresponding second connecting terminal is connected to the first connecting terminal, the length of the wire harness located in the receiving cavity is extended, so that the protective sleeve is located in the wiring recess.

[0098] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0099] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application.

Therefore, they should not be construed as limitations on this application.

Therefore, a feature defined with terms such as "first," "second," or similar expressions may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0103] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0104] In refrigerators using related technologies, a technical problem exists where the connecting wires within the interval are easily damaged during the installation of the solenoid valve, shortening the solenoid valve's lifespan and thus reducing the reliability of the refrigeration system. The inventors discovered that the cause lies in the following process: During solenoid valve assembly, the valve body is first placed inside the housing, then the second connecting terminal of the wiring harness is connected to the first connecting terminal of the valve body. Next, the multiple connecting wires within the interval are organized so that they are accommodated within the first wiring recess. Then, a cover is placed on the housing, aligning the second wiring recess with the first wiring recess, so that the second wiring recess covers the multiple connecting wires. However, due to operator error or improper wire organization, the connecting wires within the interval may not be accommodated within the first wiring recess. When the cover is placed on the housing, the connecting wires are squeezed by the front wall of the cover and the front wall of the housing, causing damage to the connecting wires. This damage can break the outer insulation layer of the connecting wires, or even cause the connecting wires to break, shortening the solenoid valve's lifespan and thus reducing the reliability of the refrigeration system.

[0105] The inventors attempted to improve the wire harness by shortening the distance between the second connecting terminal and the protective sleeve, allowing the connecting wires within the gap to be positioned within the receiving cavity, thus avoiding compression by the front walls of the cover and housing. However, limited by the wire harness manufacturing equipment and processes, there is a minimum distance between the second connecting terminal and the protective sleeve that cannot be further shortened; this minimum distance is typically 30mm. Even if the distance between the first connecting terminal and the protective sleeve is set to the minimum, the connecting wires will still be compressed by the front walls of the cover and housing. Therefore, the aforementioned technical problem cannot be solved. Improving the wire harness manufacturing equipment and processes would be quite difficult.

[0106] The inventors then attempted to increase the size of the housing and cover, placing the cover on top of the housing so that the front walls of the cover and the housing were aligned with the protective sleeve, preventing them from contacting the connecting wires located within the gap. However, increasing the size of the housing and cover hindered the miniaturization of the solenoid valve and negatively impacted the optimization of the refrigeration system's structure.

[0107] In view of this, the refrigerator of this application embodiment, by setting the first connecting terminal of the valve body to extend in the direction from the front wall of the housing to the rear wall of the housing, so that when the second connecting terminal corresponding to the first connecting terminal is connected to it, the length of the wire harness located in the receiving cavity can be extended, so that the protective sleeve is located in the wiring recess, preventing the connecting wire located in the interval from contacting the front wall of the cover and the front wall of the housing, thereby preventing the connecting wire located in the interval from being damaged, extending the service life of the solenoid valve, and improving the reliability of the refrigeration system.

[0108] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0109] refer to Figure 1 The refrigerator in this embodiment may include a cabinet 100 and a door 200. The cabinet 100 may be configured with a refrigeration compartment. The refrigeration compartment may be used to store food and other items. Exemplarily, there may be one or more refrigeration compartments. The door 200 is rotatably connected to the cabinet 100 and is used to open or close the refrigeration compartment. The door 200 may also be rotatably connected to the outer shell 500 and is used to open or close the refrigeration compartment. There may be one or more doors 200. Exemplarily, one refrigeration compartment may correspond to one door 200, or one refrigeration compartment may correspond to two doors 200, or multiple refrigeration compartments may correspond to one door 200; this embodiment will not elaborate further.

[0110] refer to Figure 2 The refrigerator in this embodiment may further include a refrigeration system 300, which can be housed within a refrigeration compartment to provide cooling capacity. Exemplarily, the refrigeration system 300 may include a compressor 310, a condenser 320, a capillary tube 330, and an evaporator 340. When the refrigeration system 300 is operating, the compressor 310 compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, and delivers the refrigerant vapor to the condenser 320. The condenser 320 liquefies the high-temperature, high-pressure refrigerant vapor to generate high-temperature, low-pressure refrigerant liquid, and delivers it to the capillary tube 330. The capillary tube 330 depressurizes the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then delivered to the evaporator 340. The evaporator 340 receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature within the refrigeration compartment.

[0111] refer to Figure 3 , Figure 4 and Figure 5The refrigeration system 300 may further include a solenoid valve 400, which controls parameters such as the flow rate and direction of the refrigerant, thereby controlling the operating state of the refrigeration system 300. Exemplarily, the solenoid valve 400 may include a housing 500, a cover 600, a valve body 700, and a wiring harness 800. The cover 600 may cover the housing 500 and form a receiving cavity with the housing 500. At least one of the front wall of the cover 600 and the front wall of the housing 500 may be provided with a wiring recess. At least a portion of the valve body 700 may be accommodated within the receiving cavity. The valve body 700 may be provided with at least one first connection terminal 710, which is located within the receiving cavity. (Reference) Figure 5 The wiring harness 800 may include a protective sleeve 820 and at least one connecting wire 810, which may be correspondingly provided with at least one first connecting terminal 710. Each connecting wire 810 may have a second connecting terminal 830 at one end. The other end of the connecting wire 810 may be electrically connected to the main control board 840. The protective sleeve 820 is sleeved on the outside of the connecting wire 810 and is spaced apart from the second connecting terminal 830. The first connecting terminal 710 may extend along the front wall of the housing 500 toward the rear wall of the housing 500, so that when the corresponding second connecting terminal 830 is connected to the first connecting terminal 710, the length of the wiring harness 800 located in the receiving cavity is extended, so that the protective sleeve 820 is located in the wiring recess.

[0112] When installing the solenoid valve 400, the second connecting terminal 830 of the wiring harness 800 can be connected to the first connecting terminal 710 of the valve body 700 first, then the protective sleeve 820 can be placed in the wiring recess, and then the cover 600 can be placed on the housing 500. Compared with the related art, where the first connecting terminal 710 extends along the rear wall of the housing 500 towards the front wall of the housing 500, in this embodiment, since the first connecting terminal 710 extends along the front wall of the housing 500 towards the rear wall of the housing 500, when the second connecting terminal 830 is connected to the first connecting terminal 710, the length of the wiring harness 800 in the receiving cavity can be extended, so that the protective sleeve 820 is located in the wiring recess, preventing the connecting wire 810 located in the interval from contacting the front wall of the cover 600 and the front wall of the housing 500, thereby preventing the connecting wire 810 located in the interval from being damaged, extending the service life of the solenoid valve 400, and improving the reliability of the refrigeration system 300.

[0113] For example Figure 4 and Figure 5As shown, the first connecting terminal 710 can extend along a first direction, from the front wall of the housing 500 to the rear wall of the housing 500. The second connecting terminal 830 can be sleeved on the first connecting terminal 710 along a second direction opposite to the first direction, so that the connecting wire 810 located in the interval is bent and located in the receiving cavity, and the protective sleeve 820 is located in the wiring recess. With this configuration, during the installation of the solenoid valve 400, the length of the wiring harness 800 located in the receiving cavity can be extended, so that the connecting wire 810 located in the interval will not come into contact with the front wall of the housing 500 and the front wall of the cover 600, thereby preventing the connecting wire 810 located in the interval from being squeezed by the front wall of the housing 500 and the front wall of the cover 600, thus preventing damage to the connecting wire 810 located in the interval, extending the service life of the solenoid valve 400, and improving the reliability of the refrigeration system 300.

[0114] Furthermore, during the installation of the solenoid valve 400, the assembly personnel can simply place the protective sleeve 820 into the wiring recess without having to place the multiple connecting wires 810 located within the interval into the wiring recess. This eliminates the need for wire management, improving the straight-through rate during the production of the solenoid valve 400 and shortening the installation time of the solenoid valve 400, thereby increasing the assembly efficiency of the refrigeration system 300.

[0115] It should be noted that the first direction refers to, for example, Figure 4 The direction x shown is hereinafter referred to as the first direction x. The second direction refers to... Figure 5 The direction y shown is hereinafter referred to as the second direction y.

[0116] For example, the housing 500 can be a split structure to facilitate the installation of the valve body 700 within the housing 500. For example Figure 6 As shown, the housing 500 may include a first housing 510 and a second housing 520. The first housing 510 has a first receiving cavity 511, which may have a third opening 5111. The second housing 520 may have a second receiving cavity 521, which may have opposing fourth openings 5211 and fifth openings 5212, with the fourth opening 5211 being connected to the third opening 5111. When assembling the solenoid valve 400, the first housing 510 can be provided first, the valve body 700 placed inside the first housing 510, and then the second housing 520 can be placed over the valve body 700 and connected to the first housing 510. Compared to a one-piece structure, configuring the housing 500 to include a first housing 510 and a second housing 520 improves the ease of assembling the solenoid valve 400.

[0117] refer to Figure 7 and Figure 8The first housing 510 may include a first base plate 5112, a first front wall 5113, a first rear wall 5114, a first side wall 5115, and a second side wall 5116. The first base plate 5112 may be a square plate, which may be horizontally arranged. The first front wall 5113 and the first rear wall 5114 may be arranged opposite each other and connected to the opposite two sides of the first base plate 5112, respectively. The first side wall 5115 and the second side wall 5116 are arranged opposite each other and connected to the other two opposite sides of the first base plate 5112, respectively. The first side wall 5115 and the second side wall 5116 are also connected to the first front wall 5113 and the first rear wall 5114. The first base plate 5112, the first front wall 5113, the first rear wall 5114, the first side wall 5115, and the second side wall 5116 form a first receiving cavity 511 with a third opening 5111.

[0118] In some possible implementations of the embodiments of this application, the first base plate 5112, the first front wall 5113, the first rear wall 5114, the first side wall 5115, and the second side wall 5116 can be an integral structure. This configuration improves the connection strength between the first base plate 5112, the first front wall 5113, the first rear wall 5114, the first side wall 5115, and the second side wall 5116, thereby improving the structural reliability of the first housing 510; and reduces the difficulty of assembling the solenoid valve 400, improving the assembly efficiency of the solenoid valve 400. Furthermore, the first base plate 5112, the first front wall 5113, the first rear wall 5114, the first side wall 5115, and the second side wall 5116 can be processed by integral molding methods such as injection molding, reducing the manufacturing difficulty of the first housing 510.

[0119] For example, the edge of the housing 500 facing away from the cover 600, such as the edge of the first base plate 5112 in the first housing 510, may be provided with a mounting portion 515 for connection with the housing 100. For example Figure 7 and Figure 8As shown, the mounting part 515 can be a plate-like structure. The mounting part 515 can be provided with a connecting through hole 5151 for a connecting bolt to pass through, so as to connect the mounting part 515 to the housing 100 via the connecting bolt. Exemplarily, the connecting through hole 5151 can be a circular through hole, a strip-shaped through hole, or a through hole of other shapes; this embodiment will not elaborate further. By providing the mounting part 515 on the edge of the housing 500 facing away from the cover 600, the housing 500 can be connected to a horizontally arranged plate-like structure in the housing 100, for example, the housing 500 can be connected to the bottom plate of the compressor compartment inside the housing 100. Compared to providing the mounting part 515 on the side wall of the housing 500 and connecting the mounting part 515 to a vertically arranged plate-like structure in the housing 100, which requires reinforcing iron to be provided on the vertically arranged plate-like structure, in this embodiment, no reinforcing iron is needed, reducing the material cost of the housing 100.

[0120] There can be multiple mounting parts 515, and multiple mounting parts 515 can be symmetrically arranged along the first center line S1 in the first housing 510 to improve the connection strength and stability between the first housing 510 and the box 100.

[0121] like Figure 7 As shown, at least one support portion 512 may be provided within the first housing 510. The support portion 512 is used to support and position the valve body 700, thereby improving the relative positional accuracy between the first housing 510 and the valve body 700. For example, the support portion 512 may be disposed on the side of the first base plate 5112 located within the first receiving cavity 511, and connected to the first side wall 5115 or the second side wall 5116. The support portion 512 can also improve the connection strength between the first base plate 5112 and the first side wall 5115, or between the first base plate 5112 and the second side wall 5116. A support surface 5121 may be provided on the side of the support portion 512 facing away from the first base plate 5112. The surface shape of the support surface 5121 may be the same as the surface shape of the outer surface of the valve body 700 to increase the contact area with the valve body 700, thereby improving its support and positioning performance for the valve body 700.

[0122] For example, there can be four support portions 512, which can be symmetrically arranged along a first center line S1. The first center line S1 can be a center line extending along a first direction x in the first housing 510. With this arrangement, the support portions 512 can provide symmetrical and stable support to the valve body 700. Figure 8As shown, a first guide portion 513 may also be provided inside the first housing 510. The first guide portion 513 may be disposed on the side of the first front wall 5113 located within the first receiving cavity 511. A first guide surface 5131 may be provided on the side of the first guide portion 513 facing away from the first bottom plate 5112. In the direction from the third opening 5111 to the first bottom plate 5112, the first guide surface 5131 is inclined from the first front wall 5113 of the first housing 510 towards the center of the first housing 510. When the valve body 700 is installed inside the first housing 510, the first guide surface 5131 can guide the valve body 700, improving the convenience of installing the valve body 700.

[0123] The first front wall 5113 of the first housing 510 may be provided with a first recess 5117, which is used to install the valve body 700 of the part 515.

[0124] An arc-shaped plate 514 may also be provided on the side of the first front wall 5113 facing away from the first receiving cavity 511. The arc-shaped plate 514 surrounds part of the first recess 5117 to surround part of the valve body 700.

[0125] The first rear wall 5114 of the first housing 510 may be provided with a second recess 5118, which is used to install the valve body 700 of the part 515.

[0126] For example, refer to Figures 4 to 6 The valve body 700 may include a coil 720, which may be located within a receiving cavity. A first connection terminal 710 includes a first connection end 711 and a second connection end 712. The first connection end 711 may be connected to the coil 720 and is located near the front wall of the housing 500. The second connection end 712 is located further away from the front wall of the housing 500 than the first connection end 711. A second connection terminal 830 may include a third connection end 831 and a fourth connection end 832. The third connection end 831 may be connected to a connecting wire 810. The fourth connection end 832 is closer to the front wall of the housing 500 than the third connection end 831 and is sleeved onto the second connection end 712. Since the first connecting end 711 is close to the front wall of the housing 500, and the second connecting end 712 is farther away from the front wall of the housing 500 than the first connecting end 711, the distance between the second connecting end 712 and the rear wall of the housing 500 can be increased, thereby increasing the remaining space inside the housing 500. When the fourth connecting end 832 of the second connecting terminal 830 is sleeved on the second connecting end 712, the length of the wire harness 800 located in the receiving cavity can be further extended, thereby preventing the connecting wire 810 located in the interval from contacting the front wall of the housing 500 and the front wall of the cover 600, and thus preventing the connecting wire 810 located in the interval from being damaged.

[0127] The valve body 700 may further include a valve core 730, which can be inserted into the coil 720. Exemplarily, the valve core 730 may be provided with an inlet pipe 740 and an outlet pipe 750. The inlet pipe 740 and the outlet pipe 750 may be connected to other pipes of the refrigeration system 300. The number of inlet pipes 740 may be one or more. The number of outlet pipes 750 may be one or more. For example... Figure 4 and Figure 6 As shown, there can be one inlet pipe 740, which can be inserted into the first recess 5117. Exemplarily, the inlet pipe 740 can also be housed within an arc-shaped plate 514, which supports and limits the inlet pipe 740. There can be two outlet pipes 750. One outlet pipe 750 can be arranged side-by-side with the inlet pipe 740. The other outlet pipe 750 can be located on the side of the valve core 730 opposite to the inlet pipe 740. The other outlet pipe 750 can be inserted into the second recess 5118.

[0128] When installing the valve body 700 into the first housing 510, the first housing 510 can be supplied first. Then, the valve core 730 is inserted into the coil 720. The coil 720 is then placed in the first receiving cavity 511 of the first housing 510, and the liquid inlet pipe 740 is placed in the first recess 5117 and the arc plate 514, with one liquid outlet pipe 750 located above the liquid inlet pipe 740 and the other liquid outlet pipe 750 placed in the second recess 5118.

[0129] refer to Figure 9 and Figure 10 The second housing 520 may include a second front wall 5213, a second rear wall 5214, a third side wall 5215, and a fourth side wall 5216. The second front wall 5213 is disposed opposite to the second rear wall 5214. The third side wall 5215 and the fourth side wall 5216 are disposed opposite to each other and are both connected to the second front wall 5213 and the second rear wall 5214. The second front wall 5213, the second rear wall 5214, the third side wall 5215, and the fourth side wall 5216 enclose a second receiving cavity 521 having a fourth opening 5211 and a fifth opening 5212, with the fourth opening 5211 abutting against the third opening 5111. The second front wall 5213 is connected to the first front wall 5113, forming the front wall of the housing 500. The second rear wall 5214 is connected to the first rear wall 5114, forming the rear wall of the housing 500. The third side wall 5215 is connected to the first side wall 5115, forming one side wall of the housing 500. The fourth sidewall 5216 is connected to the second sidewall 5116 to form another sidewall of the housing 500.

[0130] In some possible implementations of this application, the second front wall 5213, the second rear wall 5214, the third side wall 5215, and the fourth side wall 5216 can be an integral structure. This configuration improves the connection strength between the second front wall 5213, the second rear wall 5214, the third side wall 5215, and the fourth side wall 5216, thereby enhancing the structural reliability of the second housing 520; it also reduces the difficulty of assembling the solenoid valve 400 and improves the assembly efficiency of the solenoid valve 400. Furthermore, the second front wall 5213, the second rear wall 5214, the third side wall 5215, and the fourth side wall 5216 can be processed by integral molding methods such as injection molding, reducing the manufacturing difficulty of the first housing 510.

[0131] For example, the second front wall 5213 of the second housing 520 may be provided with a third recess 5217, which may be used to accommodate an outlet pipe 750 located above the inlet pipe 740, so that the outlet pipe 750 can be connected to other pipes of the refrigeration system 300.

[0132] At least one limiting portion 522 may be provided within the second housing 520. The limiting portion 522 abuts against the valve body 700 to limit the valve body 700, thereby improving the stability of the valve body 700. Exemplarily, the limiting portion 522 may be a bent plate-like structure that curves towards the valve body 700. The limiting portion 522 may be connected to one side of the third sidewall 5215 or the fourth sidewall 5216 located within the second receiving cavity 521. There may be multiple limiting portions 522, and these multiple limiting portions 522 may be symmetrically arranged along the first centerline S1.

[0133] On both sides of the first housing 510 and the opposite sides of the second housing 520, one side may be provided with a second snap-fit ​​portion 523, and the other side may be provided with a second snap-fit ​​recess 516. The second snap-fit ​​recesses 516 snap into each other. The first housing 510 and the second housing 520 are connected by the interlocking second snap-fit ​​recesses 516 and the second snap-fit ​​portions 523, which improves the ease of assembly of the first housing 510 and the second housing 520 and increases the assembly efficiency of the solenoid valve 400. In addition, the fact that both sides of the first housing 510 and the opposite sides of the second housing 520 can be connected by the interlocking second snap-fit ​​recesses 516 and the second snap-fit ​​portions 523 can prevent gaps from appearing on the opposite sides of the first housing 510 and the opposite sides of the second housing 520, thus improving the structural reliability of the housing 500.

[0134] For example Figures 7 to 10As shown, the first sidewall 5115 and the second sidewall 5116 of the first housing 510 may both be provided with a second snap-fit ​​recess 516. The third sidewall 5215 and the fourth sidewall 5216 of the second housing 520 may both be provided with a second snap-fit ​​portion 523, which can snap into the second snap-fit ​​recess 516. Alternatively, the first sidewall 5115 and the second sidewall 5116 of the first housing 510 may both be provided with a second snap-fit ​​portion 523. The third sidewall 5215 and the fourth sidewall 5216 of the second housing 520 may both be provided with a second snap-fit ​​recess 516.

[0135] The number of second snap-fit ​​recesses 516 on the first sidewall 5115 can be two, and the number of second snap-fit ​​recesses 516 on the second sidewall 5116 can also be two. Correspondingly, the number of second snap-fit ​​portions 523 on the third sidewall 5215 and the number of second snap-fit ​​portions 523 on the fourth sidewall 5216 can also be two, so as to further improve the structural reliability of the housing 500.

[0136] For example, refer to Figure 8 The second snap-fit ​​recess 516 may be disposed on the side of the first sidewall 5115 or the second sidewall 5116 facing away from the first receiving cavity 511. The second snap-fit ​​recess 516 may include a first through hole 5161 and a second through hole 5162 that are connected. The first through hole 5161 extends in a direction parallel to the first sidewall 5115 or the second sidewall 5116. The second through hole 5162 is located on the side of the first through hole 5161 away from the first center line S1, and is also located on the side of the first through hole 5161 away from the second center line S2. The second center line S2 is perpendicular to the first center line S1.

[0137] For example, refer to Figure 9 The second engaging portion 523 can be disposed on the side of the third sidewall 5215 or the fourth sidewall 5216 facing away from the second receiving cavity 521. The second engaging portion 523 can include a first connecting structure 5231 and a first protruding structure 5232. The first connecting structure 5231 can extend along the direction from the second housing 520 to the first housing 510. The first protruding structure 5232 can be disposed on the side of the first connecting structure 5231 facing away from the second receiving cavity 521. When the second housing 520 mates with the first housing 510, the first connecting structure 5231 is inserted into the first through hole 5161, and the first protruding structure 5232 can pass through the first through hole 5161 and engage with the hole wall of the first through hole 5161.

[0138] For example, such as Figure 8As shown, a second guide portion 5163 may be provided on the side of the first through hole 5161 facing away from the first receiving cavity 511, and a second guide surface 5164 may be provided on the side of the second guide portion 5163 facing the second housing 520. The second guide surface 5164 may be an arc-shaped surface. Figure 9 As shown, a third guide surface 5233 may be provided on the side of the first protruding structure 5232 facing away from the second receiving cavity 521. Along the direction from the first housing 510 to the second housing 520, the third guide surface 5233 may be inclined away from the first centerline S1. When the first protruding structure 5232 passes through the first through hole 5161, the third guide surface 5233 may contact the second guide surface 5164 to guide the first protruding structure 5232, improving the convenience of interlocking between the second engaging portion 523 and the second engaging recess 516.

[0139] For example, such as Figure 7 As shown, the first housing 510 may have a first connecting protrusion 517 on the side facing the second housing 520, and the first connecting protrusion 517 may surround at least part of the first receiving cavity 511. The second housing 520 may have a first connecting recess on the side facing the first housing 510, and the first connecting recess may be fitted onto the first connecting protrusion 517. When the first housing 510 and the second housing 520 are mated, the first connecting protrusion 517 can be inserted into the first connecting recess, which can improve the sealing performance between the first housing 510 and the second housing 520, prevent moisture, dust and other impurities from entering the housing 500, and extend the service life of the solenoid valve 400.

[0140] The cover 600 can be fitted onto the housing 500 to form a receiving cavity. For example, as shown... Figure 9 As shown, the cover 600 may be constructed with a third receiving cavity 610 having a sixth opening 611. When the cover 600 is placed on the housing 500, the sixth opening 611 may be opposite to the fifth opening 5212, and the third receiving cavity 610, together with the second receiving cavity 521 and the first receiving cavity 511, forms a receiving cavity.

[0141] At least one of the front wall of the cover 600 and the front wall of the housing 500 may be provided with a wiring recess for the wire harness 800 to pass through. For example, the front wall of the housing 500, such as the second front wall 5213, may be provided with a first wiring recess 530, which has a first opening 531 formed at the edge of the front wall of the housing 500. The front wall of the cover 600 may be provided with a second wiring recess 620, which has a second opening 621 formed at the edge of the front wall of the cover 600, opposite to the first opening 531. After the second connecting terminal 830 is sleeved onto the first connecting terminal 710, a portion of the protective sleeve 820 can be placed inside the first wiring recess 530. Then, when the cover 600 is placed on the housing 500, the second opening 621 is opposite to the first opening 531, so that the second wiring recess 620 is fitted onto another part of the protective sleeve 820. The protective sleeve 820 is simultaneously limited by the front wall of the housing 500 and the front wall of the cover 600, which improves the stability of the wire harness 800 and prevents the wire harness 800 from being pulled, causing the first connecting terminal 710 to separate from the second connecting terminal 830, thereby improving the connection reliability between the wire harness 800 and the valve body 700.

[0142] For example, the front wall of the housing 500 facing away from the receiving cavity, such as the side of the second front wall 5213 facing away from the first receiving cavity 511, may be provided with a first protrusion 532. A first wiring recess 530 is provided on the first protrusion 532 and extends through the first protrusion 532. This arrangement can extend the length of the first wiring recess 530, increase the contact area between the first wiring recess 530 and the protective sleeve 820, thereby improving the stability of the wiring harness 800 and further improving the connection reliability between the wiring harness 800 and the valve body 700.

[0143] For example, a second protrusion 622 is provided on the side of the front wall of the cover 600 facing away from the receiving cavity. A second wiring recess 620 is provided on the second protrusion 622 and extends through the second protrusion 622. This arrangement can extend the length of the second wiring recess 620, increase the contact area between the second wiring recess 620 and the protective sleeve 820, thereby improving the stability of the wiring harness 800 and further improving the connection reliability between the wiring harness 800 and the valve body 700.

[0144] The solenoid valve 400 may further include a bendable connecting plate 900, which connects the rear wall of the cover 600 and the rear wall of the housing 500, for example, a second rear wall 5214. When the connecting plate 900 is in a bent state, the cover 600 covers the housing 500. The rear wall of the cover 600 and the rear wall of the housing 500 are connected by the bendable connecting plate 900, so that the cover 600 and the housing 500 form an integral structure. During the assembly of the solenoid valve 400, the assembler does not need to remove or place the cover 600, improving the assembly efficiency of the solenoid valve 400, thereby improving the production efficiency of the refrigerator.

[0145] On the front wall of the housing 500 facing away from the receiving cavity and on the front wall of the cover 600 facing away from the receiving cavity, one may be provided with a first engaging portion 630, and the other may be provided with a first engaging recess 524. The first engaging recess 524 and the first engaging portion 630 engage with each other. The cover 600 and the housing 500 can be connected through the engaging first engaging recess 524 and the first engaging portion 630, which can improve the ease of assembly of the cover 600 and the housing 500 and improve the assembly efficiency of the solenoid valve 400.

[0146] The number of first snap-fit ​​recesses 524 on the front wall of the housing 500 can be two, and the two first snap-fit ​​recesses 524 can be located on both sides of the first wiring recess 530. Correspondingly, the number of first snap-fit ​​portions 630 on the front wall of the cover 600 can also be two, and the two first snap-fit ​​portions 630 are respectively snapped into the two first snap-fit ​​recesses 524 to improve the connection reliability between the cover 600 and the housing 500.

[0147] For example, refer to Figure 9 The first snap-fit ​​recess 524 can be disposed on the side of the housing 500 opposite to the receiving cavity, for example, it can be disposed on the side of the second front wall 5213 of the second housing 520 opposite to the second receiving cavity 521. The first snap-fit ​​recess 524 can include a third through hole 5241 and a fourth through hole 5242 that are connected. The third through hole 5241 extends in a direction parallel to the second front wall 5213. The fourth through hole 5242 is located on the side of the third through hole 5241 away from the second front wall 5213, and is located on the side of the third through hole 5241 away from the first centerline S1. (See reference) Figure 10The first engaging portion 630 can be disposed on the front wall of the cover 600 on the side facing away from the third receiving cavity 610. The first engaging portion 630 may include a second connecting structure 631 and a second protruding structure 632. The second connecting structure 631 can extend toward the sixth opening 611. The second protruding structure 632 can be disposed on the side of the second connecting structure 631 facing away from the third receiving cavity 610. When the cover 600 is placed on the housing 500, the second connecting structure 631 is inserted into the third through hole 5241, and the second protruding structure 632 can pass through the third through hole 5241 and engage with the hole wall of the third through hole 5241.

[0148] For example, a third guide portion 5243 may be provided on the side of the third through hole 5241 facing away from the second receiving cavity 521, and a fourth guide surface 5244 may be provided on the side of the third guide portion 5243 facing away from the first housing 510. The fourth guide surface 5244 may be an arc-shaped surface. A fifth guide surface 633 may be provided on the side of the second protruding structure 632 facing away from the third receiving cavity 610. When the connecting plate 900 is in the unfolded state, the third guide surface 5233 may be inclined towards the housing 500 along the orientation of the sixth opening 611. When the second protruding structure 632 passes through the third through hole 5241, the fifth guide surface 633 may contact the fourth guide surface 5244 to guide the second protruding structure 632, thereby improving the convenience of interlocking the first snap-fit ​​portion 630 and the first snap-fit ​​recess 524.

[0149] For example, when the connecting plate 900 is in a bent state, a second connecting protrusion 525 may be provided on the side of the housing 500 facing the cover 600, and the second connecting protrusion 525 may surround at least part of the second receiving cavity 521. A second connecting recess 640 may be provided on the side of the cover 600 facing the housing 500, and the second connecting recess 640 may be fitted onto the second connecting protrusion 525. When the cover 600 is placed on the housing 500, the second connecting protrusion 525 may be inserted into the second connecting recess 640, which can improve the sealing performance between the cover 600 and the housing 500, prevent moisture, dust and other impurities from entering the housing 500, and extend the service life of the solenoid valve 400.
