DETAILED DESCRIPTION

[0074] In order to make the purpose, implementation and advantages of the present application clearer, the following will combine the drawings in the exemplary embodiments of the present application to clearly and completely describe the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0075] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the subsequently described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0076] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to the clearly listed components, but can include other components that are not clearly listed or inherent to these products or devices.

[0077] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0078] The terms "first", "second", "third", etc. are used only for descriptive purposes and do not connote or imply relative importance or a number of the indicated technical features. Thus, features defined with "first", "second" or "third" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0079] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0080] In some refrigerator products, the power cord is fixed to the main control box by two screws, which has stable structure, but low assembly efficiency and high cost.

[0081] Therefore, the researchers of the embodiments of the present application consider setting a limiting structure on the main control box, so that the power cord is clamped in the limiting structure, thereby improving the assembly efficiency and reducing the cost.

[0082] According to the provisions of the national standard GB4706.1, the power cord is pulled by a pulling force of 100N, and the displacement of the power cord is not more than 2mm after 25 tests, each lasting for one second. In addition, the power cord should also meet the requirements when pushed by a pushing force of 50N. Therefore, the stability of the power cord in the limiting structure needs to be ensured.

[0083] Therefore, the limiting structure of the embodiments of the present application is provided with a first limiting part, a second limiting part and a third limiting part. The first limiting part limits the position of the power cord along the first direction, and the first direction is parallel to the extension direction of the power cord. The second limiting part limits the position of the power cord along the second direction, and the third limiting part limits the position of the power cord along the third direction. The third direction, the second direction and the first direction are perpendicular to each other. In this way, the six degrees of freedom of the power cord are limited, and the stability and reliability of the power cord relative to the main control box are ensured. The possibility of displacement of the power cord due to extrusion during the process of mounting the box cover to the main control box can be reduced, and the safety of the refrigerator can be improved.

[0084] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0085] Referring to Figure 1 Embodiments of the present application provide a refrigerator, which includes a cabinet 100 configured to form a refrigeration compartment having a taking and placing opening for storing articles.

[0086] The refrigeration compartment can be provided in plurality to expand the storage space. According to different storage temperatures of the refrigeration compartment, the refrigeration compartment can include at least one refrigerating compartment and at least one freezing compartment. Among them, the internal temperature of the refrigerating compartment can be maintained at about 0℃ to 5℃ to store articles in a refrigeration mode; the internal temperature of the freezing compartment can be maintained at about -℃ to 0℃ to store articles in a freezing mode.

[0087] In some possible implementations, at least one refrigeration compartment can also be provided as a vacuum chamber or a temperature-variable chamber, etc., and embodiments of the present application will not be described hereinafter.

[0088] Exemplarily, the refrigeration compartment can be provided with two, and the two refrigeration compartments can be stacked in a vertical direction; the two refrigeration compartments can be arranged side by side in a horizontal direction. One of them can be provided as a refrigerating compartment, and one of them can be provided as a freezing compartment.

[0089] In combination Figure 2 The cabinet 100 can include a cabinet liner and a cabinet shell 110. The cabinet liner can be configured to form a refrigeration compartment with a front opening, which is a taking and placing opening. The cabinet shell 110 can be connected to the outside of the cabinet liner to form the appearance of the refrigerator.

[0090] The cabinet 100 can also include a cabinet insulation layer, which can be provided between the cabinet liner and the cabinet shell 110. The cabinet insulation layer can thermally insulate the refrigeration compartment to minimize heat exchange between the refrigeration compartment and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0091] As Figure 2 shown, the cabinet shell 110 can include a top plate 111 and a bottom plate 112 oppositely and spacedly arranged along the height direction Z of the refrigerator, and the top plate 111 is located above the bottom plate 112. The cabinet shell 110 can also include a first side plate 113 and a second side plate 114 oppositely and spacedly arranged along the width direction X of the refrigerator, and the first side plate 113 and the second side plate 114 are respectively connected to the top plate 111 and the bottom plate 112 on both sides along the width direction X of the refrigerator. The cabinet shell 110 can also include a back plate 115 fixed to the back side of the top plate 111, the bottom plate 112, the first side plate 113 and the second side plate 114, so that the top plate 111, the bottom plate 112, the first side plate 113, the second side plate 114 and the back plate 115 form a mounting cavity with a front opening, so that the cabinet liner is mounted in the mounting cavity.

[0092] In some embodiments, the top plate 111, the first side plate 113 and the second side plate 114 are integrally formed as an integral piece, for example, two ends of a metal plate are bent towards the same side to form a U-shaped structure. In this way, the number of connection positions of the cabinet 110 is reduced, the assembly efficiency is improved, and the sealing performance of the cabinet 110 is improved.

[0093] The refrigerator of the embodiments of the present application can further include a refrigeration system for reducing the air temperature of the refrigeration compartment. The refrigeration system can be disposed in the cabinet 100, for example. The refrigeration system can include a compressor, a condenser, a throttling device and an evaporator connected in a cycle.

[0094] When the refrigeration system is operating, the compressor compresses the refrigerant vapor to generate high-temperature and high-pressure refrigerant vapor and delivers the refrigerant vapor to the condenser. The condenser liquefies the high-temperature and high-pressure refrigerant vapor to generate high-temperature and low-pressure refrigerant liquid and delivers the refrigerant liquid to the throttling device. The throttling device depressurizes the refrigerant liquid to change the high-pressure and low-temperature refrigerant liquid into low-pressure and low-temperature refrigerant liquid and delivers the refrigerant liquid to the evaporator. The evaporator receives the low-pressure and low-temperature refrigerant liquid and boils the refrigerant liquid under isobaric conditions to absorb heat and vaporize to form refrigerant vapor, thereby reducing the temperature in the refrigeration compartment.

[0095] Continuing to refer to Figure 1 The refrigerator of the embodiments of the present application can further include a door body 200 rotatably connected to the cabinet 100 to open or close the access opening. The door body 200 can be hinged to the cabinet 100, for example.

[0096] Each refrigeration compartment can be provided with one door body 200, or each refrigeration compartment can be provided with two door bodies 200, and the two door bodies 200 can be rotated in opposite directions to open or close the refrigeration compartment.

[0097] Of course, in some possible implementations, a drawer is provided in the refrigeration compartment, and an outer end of the drawer is configured to form the door body 200.

[0098] In combination Figure 1 In some embodiments of the present application, the refrigerator can further include a main control assembly 300 for supplying power to the refrigerator and controlling the operating state of the refrigerator.

[0099] The main control assembly 300 is installed on the side of the cabinet 100 away from the refrigeration compartment, which not only helps to ensure the safety of the main control assembly 300, but also avoids occupying the storage space of the refrigeration compartment.

[0100] In order to avoid the installation of the main control assembly 300 affecting the sealing performance of the cabinet, the main control assembly 300 can be installed on the cabinet shell 110 for easy maintenance. Figure 1 and Figure 2As shown, the main control assembly 300 can be installed on the top plate 111 of the cabinet 100, which is good for ventilation and heat dissipation of the main control assembly 300, and is far away from the vibration source such as the compressor of the refrigerator, so as to reduce the interference of vibration on electronic components. Figure 3 As shown, the main control assembly 300 can be installed on the back plate 115 of the cabinet 110, which is close to the components such as the compressor, so that the wiring is simple, and the main control assembly 300 is hidden in the north of the refrigerator, which does not affect the appearance of the refrigerator.

[0101] In combination Figure 4 and Figure 5 In some embodiments of the present application, the main control assembly 300 includes a main control box 310 and a main control board, and the main control box 310 is configured to form a mounting groove 311. The mounting groove 311 is open away from the cabinet 110. The main control board is fixed in the mounting groove 311, and the main control board can be connected with the main control box 310 by clamping, screwing or the like, so that the main control board is fixed in the mounting groove 311.

[0102] The main control assembly 300 further includes a box cover connected with the main control box 310 and forming a mounting cavity with the main control box 310, so that the main control board is installed in the mounting cavity. The connection between the box cover and the main control box 310 includes but is not limited to clamping, screwing or the like.

[0103] For example, when the main control board is installed on the top plate 111, the main control board can be parallel to the top plate 111. When the main control board is installed on the back plate 115, the main control board can be parallel to the back plate 115. The projection of the main control board on the top plate 111 can be rectangular, and the length direction of the main control board is parallel to the width direction of the cabinet 100, and the thickness direction of the main control board is parallel to the height direction of the cabinet 100.

[0104] In combination Figure 6 The main control assembly 300 can further include a power line 330, one end of which is electrically connected with the main control board, and the other end of which is led out to the outside of the main control box 310. The power line 330 can include a fixing seat 331 and a wire body 332 fixed in the power seat, one end of the wire body 332 is electrically connected with the main control board, and the other end of the wire body 332 is led out to the outside of the main control box 310; the fixing seat 331 is fixed on the main control box 310, so that the position of the power line 330 relative to the main control box 310 is fixed.

[0105] The main control box 310 of the present application further forms a limiting structure 400 on one side of the mounting groove 311, so as to avoid the limiting structure 400 affecting the installation of the main control board and the electronic components in the mounting groove 311. The limiting structure 400 is configured to clamp with the fixing seat 331 of the power line 330, so as to limit the relative position relationship between the power line 330 and the main control box 310, so that the power line 330 is stably and reliably fixed on the main control box 310.

[0106] The limiting structure 400 is configured to form a threading passage 401 for the other end of the wire 332 to pass out to the outside of the main control box 310.

[0107] In some embodiments of the present application, the limiting structure 400 is configured to form a first limiting part 410 configured to be clamped with the fixing seat 331 to limit the position of the fixing seat 331 along a first direction. The first limiting part 410 is clamped with the fixing seat 331 of the power cord 330 to limit the position of the fixing seat 331 along the first direction. In combination Figure 5 , the first limiting part 410 can not only limit the position of the fixing seat 331 along the positive direction of the first direction, but also limit the position of the fixing seat 331 along the negative direction of the first direction.

[0108] The limiting structure 400 is configured to form a second limiting part 420 configured to be clamped with the fixing seat 331 to limit the position of the fixing seat 331 along a second direction. The second limiting part 420 is clamped with the fixing seat 331 of the power cord 330 to limit the position of the fixing seat 331 along the second direction. In combination Figure 5 , the second limiting part 420 can not only limit the position of the fixing seat 331 along the positive direction of the second direction, but also limit the position of the fixing seat 331 along the negative direction of the second direction.

[0109] The limiting structure 400 is configured to form a third limiting part 430 configured to be clamped with the fixing seat 331 to limit the position of the fixing seat 331 along a third direction. The third limiting part 430 is clamped with the fixing seat 331 of the power cord 330 to limit the position of the fixing seat 331 along the third direction. In combination Figure 5 , the third limiting part 430 can not only limit the position of the fixing seat 331 along the positive direction of the third direction, but also limit the position of the fixing seat 331 along the negative direction of the third direction.

[0110] In the embodiments of the present application, the first direction is parallel to the extension direction of the threading passage 401, corresponding to the Y-axis direction in Figure 5 ; the first direction, the second direction and the third direction are perpendicular to each other; and the third direction is perpendicular to the main control board. The second direction can correspond to the X-axis direction in Figure 5 , and the third direction can correspond to the Z-axis direction in Figure 5 .

In this way, the position of the fixing seat 331 in six directions is limited by the limiting structure 400, so that the position of the fixing seat 331 relative to the main control box 310 is reliably fixed, the possibility of displacement of the power line 330 relative to the main control box 310 is reduced, and the yield of the refrigerator is improved. Moreover, the limiting structure 400 is clamped with the fixing seat 331, so that the assembly of the power line 330 and the main control box 310 is simple and convenient, and the assembly efficiency is improved.

[0114] The first limiting wall 412 is configured to form a threading passage 401 to allow the power line 330 to pass out to the outside of the main control box 310.

[0115] Part of the fixing seat 331 is clamped between the first clasp 411 and the first limiting wall 412, thereby limiting the position of the fixing seat 331 along the first direction.

[0116] Among them, along the first direction, the first clasp 411 is closer to the mounting groove 311 relative to the first limiting wall 412. In combination Figure 5 with the direction shown, the first clasp 411 can abut against the fixing seat 331 to limit the position of the fixing seat 331 along the positive direction of the first direction Y; and the first limiting wall 412 can abut against the fixing seat 331 to limit the position of the fixing seat 331 along the negative direction of the first direction Y.

[0117] In combination Figure 6 and Figure 7 , the fixing seat 331 provided by the embodiment of the application can include a seat body 3311 which can extend along the first direction and form a through hole extending along the first direction, and part of the wire body 332 is arranged and fixed in the through hole.

[0118] In some embodiments, the gap between the fixing seat 331 and the box cover can be less than 1mm, which can prevent impurities such as mosquitoes from entering the inside of the main control box 310.

[0119] The fixing seat 331 can include a first plate body part 3312, which can be located on a side of the seat body 3311 facing the limiting structure 400, for cooperating with the limiting structure 400 to limit the position of the fixing seat 331 relative to the main control box 310. The extension plane of the first plate body part 3312 can be parallel to the first direction.

[0120] The fixing seat 331 can further include a second plate body part 3313, which is respectively located on both sides of the seat body 3311 along the second direction, and the second plate body part 3313 is located on an end of the seat body 3311 along the first direction away from the mounting groove 311. The extension plane of the second plate body part 3313 can intersect the first direction, and the second plate body part 3313 can intersect the first plate body part 3312. Exemplarily, the second plate body part 3313 is perpendicular to the first plate body part 3312.

[0121] The seat body 3311, the first plate body part 3312, and the second plate body part 3313 can be an integral piece integrally formed, which is stable in structure and convenient for forming and processing.

[0122] The first plate body part 3312 is configured to form a first cooperation face 3314, which is located on a side of the first plate body part 3312 along the first direction away from the second plate body part 3313. The second plate body part 3313 is configured to form a second cooperation face 3315, which is located on a side of the second plate body part 3313 along the first direction away from the first plate body part 3312.

[0123] In combination Figure 5 to Figure 7 The first clamping buckle 411 can abut against the first cooperation face 3314, and the first limiting wall 412 can abut against the second cooperation face 3315, so as to limit the position of the fixing seat 331 along the first direction.

[0124] In the embodiments of the present application, the first limiting part 410 includes the first clamping buckle 411 and the first limiting wall 412 arranged at intervals along the first direction, and the first clamping buckle 411 and the first limiting wall 412 are used to limit the position of the fixing seat 331 along the first direction, which is stable and reliable in limiting. Moreover, the cooperation of the first clamping buckle 411 and the first limiting wall 412 helps to improve the convenience of assembling the fixing seat 331 and the limiting seat.

[0125] In combination again Figure 5 The limiting structure 400 includes a limiting bottom wall 440, and the extension plane of the limiting bottom wall 440 intersects the extension plane of the first limiting wall 412. Exemplarily, the extension plane of the limiting bottom wall 440 is perpendicular to the extension plane of the first limiting wall 412. The limiting bottom wall 440 is recessed along the third direction Z to form a first hollow part 441.

[0126] In the embodiment of the present application, the limiting bottom wall 440 is formed with a through hole penetrating through the thickness direction thereof to form a first hollow part 441. The thickness direction of the limiting bottom wall 440 is parallel to the third direction Z. In this way, the limiting structure 400 is simple to form, which helps to reduce the processing cost.

[0127] Of course, in some possible implementation manners, the first hollow part 441 can also be a groove type structure arranged on the limiting bottom wall 440, which provides a deformation space for the first buckle 411 and helps to fix the fixing seat 331 into the first buckle 411 and the first limiting wall 412.

[0128] In some embodiments, the limiting bottom wall 440 can be further provided with a second hollow part in the form of a through hole, which can not only reduce the weight of the main control box 310, but also serve as a process hole for injection molding of the main control box 310.

[0129] In the embodiment of the present application, the first limiting wall 412 is connected to the side of the limiting bottom wall 440 away from the mounting groove 311, so that the first limiting wall 412 is located outside the limiting bottom wall 440. In this way, the position of the fixing seat 331 along the first direction Y can be limited.

[0130] The first buckle 411 is located in the first hollow part 441, so that the first hollow part 441 provides a space for elastic deformation of the first buckle 411. The first buckle 411 is connected to the limiting bottom wall 440.

[0131] In some embodiments, the first buckle 411 can be provided with one, which is beneficial to simplify the structure.

[0132] In other embodiments, the first buckle 411 can be provided with a plurality of first buckles 411, which are arranged at intervals along the second direction. For example, the first buckle 411 is provided with two first buckles 411, and the two first buckles 411 are respectively located on both sides of the threading channel 401 along the second direction. In this way, the stress limitation of the fixing seat 331 can be more balanced.

[0133] The limiting structure 400 of the embodiment of the present application is provided with the limiting bottom wall 440 intersecting with the first limiting wall 412, and the first hollow part 441 is arranged on the limiting bottom wall 440 to provide a space for elastic deformation of the first buckle 411, so that the first buckle 411 can be elastically deformed, and the fixing seat 331 can be fixed into the first buckle 411 and the first limiting wall 412.

[0134] Continuing to refer to Figure 5The first latch 411 has a first end and a second end along the first direction Y. The first end of the first latch 411 is connected to the limiting bottom wall 440, and the first end of the first latch 411 is closer to the first limiting wall 412 than the second end. The first end of the first latch 411 and the first limiting wall 412 are spaced apart along the first direction Y. The second end of the first latch 411 forms a first engaging portion 4111, a portion of which protrudes from the limiting bottom wall 440 and is used to abut against the fixing seat 331, thereby limiting the position of the fixing seat 331. The portion of the first engaging portion 4111 protruding from the limiting bottom wall 440 is opposite to the first limiting wall 412 along the first direction Y and is spaced apart. Thus, the fixing seat 331 can be latched between the first engaging portion 4111 and the first limiting wall 412 to limit its position along the first direction Y.

[0135] The side of the first latching part 4111 facing the first limiting wall 412 forms an abutting surface 4112 that abuts against the fixing seat 331. The abutting surface 4112 can abut against the first mating surface 3314 of the fixing seat 331, thereby limiting the position of the fixing seat 331.

[0136] The first engaging portion 4111 forms an inclined surface 4113 on the side opposite to the abutment surface 4112 along the first direction Y. Along the first direction Y, from the second end to the first end of the first engaging portion 4111, the height of the inclined surface 4113 protruding from the limiting bottom wall 440 gradually increases. Thus, along the first direction Y, the end of the inclined surface 4113 opposite to the abutment surface 4112 protrudes less from the limiting top wall, which is beneficial for the fixing seat 331 to engage between the abutment surface 4112 and the first limiting wall 412; while the end of the inclined surface 4113 closer to the abutment surface 4112 protrudes more from the limiting top wall, which helps to form a larger abutment surface 4112 and ensures the reliability of the abutment surface 4112 abutting against the fixing seat 331.

[0137] In this embodiment of the application, the first buckle 411 forms a first engaging portion 4111, the first engaging portion 4111 forms an abutting surface 4112 opposite to the first limiting wall 412, and is used to abut against the fixing seat 331; the first engaging portion 4111 also forms an inclined surface 4113, so that the fixing seat 331 can be easily engaged between the abutting surface 4112 and the first limiting wall 412.

[0138] like Figure 5 As shown, in some embodiments of this application, a first groove 442 extending along a first direction is provided on the limiting bottom wall 440. When two first buckles 411 are provided, the first groove 442 can be located between the two first buckles 411. The first groove 442 can be opposite to the threading channel 401 along the first direction Y.

[0139] The fixed seat 331 is provided with a protruding part 333 on the side facing the limiting bottom wall 440. The protruding part 333 can be provided on the first plate part 3312 of the fixed seat 331 on the side facing the limiting bottom wall 440. Exemplarily, the protruding part 333 can be provided with two, which are arranged at intervals along the first direction.

[0140] The protruding part 333 is located in the first groove 442 and used to abut against the groove wall of the first groove 442. The first groove 442 can extend to the first limiting wall 412, so that part of the first limiting wall 412 forms the groove wall of the first groove 442. The side of the first limiting wall 412 facing the first groove 442 can be provided with a protruding part 4121, which can be located on the side of the threading channel 401 facing the limiting bottom wall 440. The protruding part 4121 can be used to abut against the protruding part 333.

[0141] Through the cooperation of the protruding part 333 and the first groove 442, not only can the protruding part 333 limit the position of the fixed seat 331 along the first direction, but also can play a positioning role and a guiding role when the fixed seat 331 is installed.

[0142] In some embodiments of the present application, in combination with Figure 5 , Figure 8 to Figure 10 The second limiting part 420 includes two second limiting walls 421, which are opposite and have intervals along the second direction X; the two second limiting walls 421 are connected with the limiting bottom wall 440. The ends of the two second limiting walls 421 away from the installation slot 311 can be connected with the first limiting wall 412, which helps to improve the structural strength of the limiting structure 400.

[0143] Part of the fixed seat 331 is clamped between the two second limiting walls 421 to limit the position of the fixed seat 331 along the second direction X. The two second limiting walls 421 limit the positive and negative directions of the fixed seat 331 along the second direction X, respectively.

[0144] The first buckle 411 is located between the two second limiting walls 421 to avoid affecting the position limitation of the second limiting wall 421 on the fixed seat 331.

[0145] In combination with Figure 11 and Figure 12 In some embodiments, the seat body 3311 of the fixed seat 331 cooperates with the threading channel 401 to limit the position of the fixed seat 331 along the second direction. In this way, the limiting structure 400 improves the position limitation of the fixed seat 331 along the second direction.

[0146] The second limiting part 420 of the embodiment of the present application limits the position of the fixing seat 331 along the second direction X by setting two second limiting walls 421, which has the advantages of simple structure, limiting effect, no influence on the fixing seat 331 being clamped between the first buckle 411 and the first limiting wall 412, simple assembly of the fixing seat 331 and the limiting structure 400, and improvement of the assembly efficiency.

[0147] In some embodiments of the present application, in combination with Figure 5 , the third limiting part 430 includes a limiting bottom wall 440 and a third limiting wall 431, the third limiting wall 431 is opposite to the limiting bottom wall 440 along the third direction and has a spacing. At least one of the first limiting wall 412 and the second limiting wall 421 is connected with the third limiting wall 431 at one end away from the limiting bottom wall 440.

[0148] Exemplarily, in combination with Figure 9 and Figure 10 , the two second limiting walls 421 are respectively provided with the third limiting wall 431 at one end away from the limiting bottom wall 440, and the two third limiting walls 431 can be inclined towards each other, which can limit the position of the fixing seat 331 along the third direction and the position of the fixing seat 331 along the second direction.

[0149] Exemplarily, in combination with Figure 5 , the first limiting wall 412 is provided with the third limiting wall 431 at one end away from the limiting bottom wall 440, and the third limiting wall 431 is disconnected at a position corresponding to the threading channel 401, so that the third limiting wall 431 is divided into two segments. In combination with Figure 11 and Figure 12 , the third limiting wall 431 abuts against the second plate body part 3313 of the fixing seat 331 to limit the position of the fixing seat 331 along the third direction. In some embodiments, part of the third limiting wall 431 is inclined relative to the limiting bottom wall 440, which can limit the position of the fixing seat 331 along the second direction and the third direction at the same time.

[0150] Part of the fixing seat 331 is clamped between the limiting bottom wall 440 and the third limiting wall 431, as shown in Figure 5 , the limiting bottom wall 440 limits the position of the fixing seat 331 along the negative direction of the third direction, and the third limiting wall 431 limits the position of the fixing seat 331 along the positive direction of the third direction.

[0151] In the embodiments of the present application, the limiting bottom wall 440 and the third limiting wall 431 are used to limit the position of the fixing seat 331 along the third direction, which has the advantages of simple structure and convenience of assembly of the fixing seat 331 and the limiting structure 400.

[0152] Referring to Figure 11 and Figure 12In some embodiments, the main control assembly 300 further comprises a grounding member 320 which is clamped with the main control box 310. In comparison with the threaded connection of the grounding member 320 and the main control box 310, the connection of the grounding member 320 and the main control box 310 is more convenient, and the assembly efficiency of the main control assembly 300 is improved.

[0153] As shown in Figure 13 and Figure 14 , the grounding member 320 can be located outside the mounting groove 311, and the grounding member 320 can be located on one side of the limiting structure 400 along the second direction X, so as to facilitate the connection of the grounding wire and the grounding member 320, and realize the grounding of the main control board.

[0154] Exemplarily, the main control box 310 is provided with a third buckle 317 which is clamped with the grounding member 320. The third buckle 317 can be provided with two, and the two third buckles 317 can be spaced apart along the second direction X, so as to improve the stability of the clamping of the grounding member 320.

[0155] The main control box 310 is further configured to form a second groove 318, and the opening direction of the second groove 318 is the same as that of the mounting groove 311. The groove side wall of the second groove 318 protrudes towards the inside of the second groove 318, so as to form one of the third buckles 317. The other third buckle 317 can be arranged on the groove bottom wall of the second groove 318 and has a spacing between the groove side wall of the second groove 318. The end of the third buckle 317 away from the groove bottom wall forms a third clamping portion, and the third clamping portion is opposite to the other third buckle 317 along the second direction. In this way, the spacing between the third buckle 317 and the groove side wall of the second groove 318 allows the third buckle 317 to elastically deform relative to the groove side wall, which helps to improve the convenience of clamping the grounding member 320 between the two third buckles 317.

[0156] In combination with Figure 11 and Figure 12 , the side of the third buckle 317 towards the groove bottom wall of the second groove 318 is clamped with the grounding member 320, so as to fix the grounding member 320 in the second groove 318.

[0157] Continuing to refer to Figure 13 and Figure 14 , the groove side wall of the second groove 318 can be further provided with a protruding rib 3181, which helps to reduce the contact area between the grounding member 320 and the groove side wall of the second groove 318, so that the grounding member 320 is more smoothly clamped into the second groove 318; and the protruding rib 3181 can also improve the stability of the installation of the grounding member 320 in the second groove 318.

[0158] The groove bottom wall of the second groove 318 is also provided with a threaded hole, and the grounding piece 320 is provided with a through hole. In this way, a fastener such as a screw is screwed through the hole on the grounding wire, the through hole on the grounding piece 320, and the threaded hole, so that the grounding wire is electrically connected with the grounding piece 320, and the grounding piece 320 is more stably mounted on the main control box 310.

[0160] The edge of the main control box 310 is provided with a mounting edge 312. The mounting edge 312 can be annular and is arranged at the edge of the main control box 310.

[0161] The mounting edge 312 is located on the inner side of the box shell 110 and forms a contact surface with the box shell 110. The limiting structure 400 is arranged on the mounting edge 312 and located on the outer side of the box shell 110. The second groove 318 is arranged on the mounting edge 312 and located on the outer side of the box shell 110.

[0162] In the embodiments of the present application, the mounting edge 312 is arranged at the edge of the main control box 310, and the mounting opening 1101 is arranged on the box shell 110, so that part of the main control box 310 is embedded into the box shell 110 through the mounting opening 1101, and the limiting structure 400 is located outside the box shell 110. The surface contact between the mounting edge 312 and the box shell 110 helps to improve the sealing performance between the main control box 310 and the box shell 110. Moreover, the main control box 310 is installed outward from the box shell 110, and under the action of the foaming layer between the box shell 110 and the tank, the cooperation between the mounting edge 312 and the box shell 110 is more stable.

[0163] In combination Figure 13 In the embodiments of the present application, the main control box 310 includes a box bottom wall 313. When the main control box 310 is installed on the top plate 111, the box bottom wall 313 can be parallel to the top plate 111.

The mounting edge 312 is arranged on the side of the outer enclosing wall 315 away from the inner enclosing wall 314, and the mounting edge 312 can be parallel to the box bottom wall 313.

[0166] The peripheral wall 315 can be provided with a threading hole, so that the cable in the wiring channel 3131 can be threaded out to the outside of the main control box 310 through the threading hole.

[0167] The box bottom wall 313 and the inner enclosing wall 314 in the wiring channel 3131 are respectively provided with a wire harness buckle 316 to limit and constrain the cable, so as to avoid the weak current wire harness from touching the components on the main control board and causing EMC disqualification. The wire harness buckle 316 can be provided with a plurality of wire harness buckles 316, and the plurality of wire harness buckles 316 are arranged in the extension direction of the wiring channel 3131.

[0168] The wire harness buckle 316 can be substantially U-shaped and open towards the box bottom wall 313.

[0169] Referring to Figure 18 In some embodiments, part of the inner enclosing wall 314 protrudes towards the peripheral wall 315 to form a protruding wall 3151, and the protruding wall 3151 protrudes towards the wiring channel 3131. The protruding wall 3151 is provided with a wire harness buckle 316, and the wire harness buckle 316 faces the wiring channel 3131. The inner side of the protruding wall 3151 is provided with a second buckle 3152, and the second buckle 3152 is buckled with the main control board. In this way, the main control board can be buckled and positioned, which helps to fixedly connect the main control board and the main control box 310.

[0170] In combination Figure 17 and Figure 18 The second buckle 3152 can include a buckling arm and a second buckling portion. The buckling arm is arranged on the inner side of the protruding wall 3151 and can be perpendicular to the box bottom wall 313.

The second buckling portion protrudes into the mounting groove 311 away from the protruding wall 3151, and the side of the second buckling portion facing the box bottom wall 313 is used for buckling with the main control board.

[0171] Exemplarily, the main control box 310 is an integral piece formed integrally, which is stable in structure and convenient to process.

[0172] The main control box 310 of the embodiment of the application forms the wiring channel 3131 to arrange the cable connected with the main control board. The wire harness buckle 316 is arranged in the wiring channel 3131 to limit and constrain the cable, so as to avoid the weak current wire harness from touching the components on the main control board. The second buckle 3152 is arranged on the inner enclosing wall 314 to buckle with the main control board, so as to fixedly connect the main control board and the main control box 310.
