In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0065] The wire controller involved in the present application is mainly used to control the switch of household appliances such as air conditioners or adjust the target temperature. The wire controller is generally installed on the wall of the room.

[0066] The wire controller of the air conditioner in the kitchen, bathroom, etc. is used in an environment with high humidity and there is a risk of contact with water. Therefore, high requirements are placed on the waterproofness of the wire controller and the air conditioner configured in this environment.

[0067] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0068] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0069] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0070] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0071] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0072] The user can turn the air conditioner on or off by controlling the switch of the wire controller, or the user can adjust the target temperature of the air conditioner through the touch screen or buttons, which is more convenient and more practical.

[0073] The outer shell of the wire controller is exposed to the air, and it is connected to the power supply through a power cord to power the wire controller. The traditional wire controller is provided with a threading hole, and the power cord is directly connected to the wire controller through the threading hole, which makes it easy for water to enter.

[0074] In order to further improve the sealing effect of the wire controller and prevent external moisture or water from entering the wire controller and affecting the operation of the electronic components inside the wire controller, the present application proposes a wire controller with better sealing performance.

[0075] refer to Figure 1 , Figure 2The wire controller proposed in the present application includes a first shell 200 and a second shell 700 that can be buckled together. The first shell 200 and the second shell 700 constitute the outer shell of the wire controller. The first shell 200 and the second shell 700 are detachably connected by buckles or fasteners.

[0076] A closed installation cavity is formed in the first shell 200 and the second shell 700 , and the installation cavity is configured to be used for installing components such as the power board 600 and the main control board 400 .

[0077] The display unit 100 is connected to the outer side of the first housing 200 , and the display unit 100 is mainly a liquid crystal panel.

[0078] In order to improve the aesthetics and integrity of the surface of the wire controller and reduce the connection analysis on the surface of the wire controller, the liquid crystal panel is fixed to the outer surface of the first shell 200 by pasting.

[0079] refer to Figure 3 A fixing recess 210 is formed on the outer surface of the first shell 200. The depth of the fixing recess 210 matches the thickness of the liquid crystal panel. The display is attached to the fixing recess 210 by hot melt adhesive, so that the outer surface of the wire controller is flush, which ensures aesthetics, avoids dust accumulation, and facilitates cleaning.

[0080] refer to Figure 4 In some embodiments of the present application, a lapped outer edge 220 is formed on the peripheral side of the first shell 200, and the lapped outer edge 220 is integrally formed with the first shell 200. The lapped outer edge 220 extends toward the second shell 700. In the connected state, the lapped outer edge 220 covers the outer side of the second shell 700, further improving the waterproof and moisture-proof effect.

[0081] In order to further improve the sealing effect, a sealing ring 300 is further connected between the first shell 200 and the second shell 700 .

[0082] A sealing groove 260 is formed inside the first housing 200 . The depth of the sealing groove 260 is smaller than the thickness of the sealing ring 300 . The sizes of the sealing ring 300 and the sealing groove 260 match those of the second housing 700 .

[0083] During installation, first place the sealing ring 300 in the sealing groove 260, and then cover the first shell 200 on the second shell 700. Then, the contact position between the second shell 700 and the first shell 200 is further sealed by the sealing ring 300 to reduce water from entering the installation cavity.

[0084] The sealing groove 260 may be a continuous groove structure formed along the circumference of the first shell 200 , or may be a plurality of limiting grooves dispersedly arranged along the circumference of the first shell 200 , and its main function is to preliminarily fix the sealing ring 300 .

[0085] That is, before the first housing 200 and the second housing 700 are connected and fixed, the sealing ring 300 is preliminarily fixed in the sealing groove 260 .

[0086] Of course, the sealing groove 260 may also be formed on the upper surface of the second housing 700 that contacts the first housing 200 .

[0087] refer to Figure 6-Figure 8 The second shell 700 specifically includes a connecting outer edge 701 and a mounting portion 702 , and the mounting portion 702 and the connecting outer edge 701 are integrally formed by injection molding.

[0088] The mounting cavity is formed in the mounting portion 702 . When the sealing groove portion 260 is located on the second shell 700 , it is specifically arranged on the connecting outer edge 701 . When connected, the connecting outer edge 701 on the second shell 700 is fixed on the first shell 200 .

[0089] In some embodiments of the present application, in order to improve the stability of the connection between the first shell 200 and the second shell 700 and avoid loosening, the first shell 200 and the second shell 700 are detachably connected via a first fastener 710 .

[0090] The first fastener 710 is specifically a fastening screw. Considering the aesthetics during use and reducing the connection analysis on the surface of the wire controller, the first fastener 710 passes through the second shell 700 and is fixed on the first shell 200 .

[0091] That is, a first connection hole is provided on the connection outer edge 701 of the second shell 700 , and a first protrusion 230 extending toward the second shell 700 is formed on the inner side of the first shell 200 .

[0092] The first protrusion 230 is integrally formed with the first shell 200 and extends toward the second shell 700 , and is specifically used to increase the connection thickness, thereby improving the connection accuracy of the first fastener 710 without increasing the thickness of the first shell 200 .

[0093] A threaded hole is formed in the first protrusion 230 , and the first fastener 710 passes through the first connection hole on the connecting outer edge 701 , and the end portion is connected to the corresponding first protrusion 230 .

[0094] The number of the first fasteners 710 is determined according to the actual size of the wire controller. For example, the wire controller is square in shape as a whole, and a first connecting hole is provided at each of the four corners connecting the outer edge 701. Correspondingly, four first protrusions 230 are provided on the first shell 200, and the second shell 700 is fixed to the first shell 200 by the four first fasteners 710.

[0095] Next, the connection and fixation of the components included in the first housing 200 and the second housing 700 are described in detail:

[0096] At least a power board 600 and a main control board 400 are disposed in the installation inner cavity. The power board 600 is fixed on the inner side of the second shell 700 , and the main control board 400 is fixed on the inner side of the first shell 200 .

[0097] refer to Figure 4 , Figure 5 Specifically, a second protrusion 270 is disposed inside the first shell 200 . The second protrusion 270 is similar to the first protrusion 230 . The second protrusion 270 is integrally formed with the first shell 200 and extends toward the second shell 700 .

[0098] The thickness of the second convex portion 270 is smaller than that of the first convex portion 230 . Specifically, the sum of the thickness of the second convex portion 270 and the main control board 400 is not greater than the thickness of the first convex portion 230 .

[0099] A threaded hole is formed on the second protrusion 270 , and a second connecting hole is provided at a corresponding position of the main control board 400 . The second fastener 410 passes through the second connecting hole and is fixed to the second protrusion 270 .

[0100] refer to Figure 5 In some embodiments of the present application, in order to reduce the number of openings of the main control board 400 , in addition to fixing the main control board 400 by the second fastener 410 , auxiliary fixing is also performed by the upper support portion 250 .

[0101] The upper support portion 250 is specifically formed on the inner side of the first shell 200 , and a support surface facing the first shell 200 is formed on the upper support portion 250 . The upper support portion 250 and the second protrusion 270 are arranged opposite to each other.

[0102] That is, both ends of the main control board 400 are fixedly connected by the upper support portion 250 and the second fastener 410 respectively.

[0103] During installation, one end of the main control board 400 is first clamped on the upper support portion 250 , and then the other end of the main control board 400 is connected and fixed by the second fastener 410 . Then, the main control board 400 only needs to have a hole opened in one section.

[0104] After the main control board 400 is connected, a PC film is attached to the surface of the main control board 400.

[0105] 500, used to protect the components on the main control board 400 after the equipment is disassembled.

[0106] In some embodiments of the present application, in order to improve the structural stability of the first shell 200 and reduce deformation, reinforcing ribs 240 are further formed on the inner surface of the first shell 200. The reinforcing ribs 240 are arranged vertically and horizontally to help ensure its structural strength.

[0107] refer to Figure 8 In some embodiments of the present application, a connecting portion 780 is formed at the bottom of the second shell 700 , and the connecting portion 780 is specifically a structure formed at the bottom of the second shell 700 and extending toward the inside and outside of the second shell 700 .

[0108] The overall thickness of the connecting portion 780 is greater than that of the second shell 700 , which is beneficial to improving the stability of the connection of the power board 600 .

[0109] The connecting portion 780 is connected to the conductive portion 730 , and the conductive portion 730 is made of a material such as copper that can achieve a conductive function.

[0110] The outer side of the conductive part 730 is configured to be connected to the power supply line 783 through the first crimping part 781 , and the inner side of the conductive part 730 is configured to be detachably connected to the power board 600 through the second crimping part 760 .

[0111] Specifically, the connecting portion 780 and the second shell 700 are integrally formed by injection molding, a through hole is formed in the connecting portion 780 , and the conductive portion 730 is plugged into the connecting portion 780 .

[0112] refer to Fig. 9 , Fig.10 In order to improve the stability of the connection and the efficiency of assembly and disassembly, internal threads are formed at both ends of the conductive part 730, and the first crimping part 781 and the second crimping part 760 are both wiring screws.

[0113] The connection screws used by the first crimping portion 781 and the second crimping portion 760 both include an intermediate pad, which is in contact and connected with the conductive portion 730, which is beneficial to increase the contact area and improve the stability of the connection.

[0114] During specific installation, the first crimping part 781 connects one end of the power supply line 783 to the conductive part 730, and the second crimping part 760 connects the terminal on the power board 600 to the conductive part 730. Then, through the conversion of the conductive part 730, the power supply line 783 can supply power to the power board 600.

[0115] The power board 600 and the main control board 400 are connected in a plug-in structure through plug-in terminals, so that the main control board 400 is powered.

[0116] The wire controller realizes the switching through the conductive part 730, which can prevent the power supply line 783 from directly passing through the second shell 700 into the installation cavity, reduce the generation of connection analysis, and prevent external moisture or dust from entering the installation cavity.

[0117] Reference again Figure 8 In order to improve the regularity of the power supply line 783 and protect the power supply line 783 from being compressed, a supporting outer edge 782 extending outward is formed at the bottom of the second shell 700. The height of the supporting outer edge 782 is not less than the width of the power supply line 783. The power supply line 783 passes through the supporting outer edge 782 and is connected to the conductive part 730.

[0118] refer to Fig.13 In order to form a closed path, two conductive parts 730 are connected to the bottom of the second shell 700 to connect the two poles of the power supply.

[0119] Specifically, a wire passing slot 7821 is provided on the outer edge 782 of the support, and the wire passing slot 7821 is configured for the power wire 783 to pass through.

[0120] refer to Figure 7 Specifically, in order to adapt to the installation height of the main control board 400 and provide stable support for the power board 600, a lower support portion 750 extending upward is formed at the bottom of the installation cavity.

[0121] A support position is formed on the lower support portion 750, and the bottom of the power board 600 is supported on the support position to prevent the formation of gaps between other positions of the power board 600 and the bottom of the installation cavity after the first crimping portion 781 is connected in the installation state, resulting in poor stability of the power board 600.

[0122] refer to Figure 6 In some other embodiments of the present application, in order to further improve the stability of the connection of the power board 600, similar to the main control board 400, the power board 600 is also fixed to the bottom of the installation cavity by a third fastener 610.

[0123] A third protrusion extending upward is formed at the bottom of the installation cavity, a threaded hole is formed in the third protrusion, a third connecting hole is opened on the power board 600, and the third fastener 610 is configured to be fixed on the third protrusion through the third connecting hole.

[0124] Similarly, in order to reduce the number of openings on the power board 600 and improve the utilization of the power board 600 , the power board 600 is auxiliaryly fixed by a lower limit portion 740 .

[0125] The lower limiting portion 740 and the third protrusion are respectively disposed at two opposite ends of the power board 600 to improve the fixing effect of the power board 600 .

[0126] A downward limiting end face is formed on the lower limiting portion 740. During installation, the power board 600 is first plugged under the limiting end face, and the bottom is supported by the lower support portion 750. The power board 600 is constructed so that one end is in contact with and connected to the bottom of the lower limiting portion 740, and the other end is detachably connected to the lower support portion 750 by a fastening screw.

[0127] refer to Fig.10 In some other embodiments of the present application, in order to facilitate connection and fixation and improve the sealing effect of the second shell 700, a protective shell 800 is further provided on the outer side of the second shell 700.

[0128] The protective shell 800 and the second shell 700 are detachably connected by means of snaps.

[0129] A accommodating cavity is formed inside the protective shell 800, and the shape of the mounting portion 702 of the second shell 700 is matched. During installation, the protective shell 800 is first fixed to the wall by fixing screws 840, and then the connected first shell 200 and second shell 700 are fixed to the protective shell 800.

[0130] Referring to 8 and 11 , specifically, a snap-fit ​​portion 770 is provided on the outer wall of the second shell 700 , and a buckle portion 810 is correspondingly provided on the inner side of the protective shell. The protective shell is detachably connected to the outer side of the second shell 700 through the buckle.

[0131] Specifically, the protective shell 800 is also formed with a supporting outer edge 782 that is in contact with the connecting outer edge 701. In order to avoid interference between the fixing screw 840 and the second shell 700, a fixing protrusion 830 is also formed on the supporting outer edge 782. A penetrating fixing hole is formed in the fixing protrusion 830, and the fixing screw 840 is fixed to the wall through the fixing hole.

[0132] Correspondingly, an avoidance portion 720 is formed at a corresponding position of the second shell 700 , and the avoidance portion 720 corresponds to the fixing protrusion 830 one by one, so as to avoid interference between the second shell 700 and the protective shell 800 .

[0133] In order to further improve the stability of the connection, a plurality of positioning recesses 820 are dispersedly formed on the protective shell 800, and a positioning protrusion 790 adapted to each positioning recess 820 is formed on the second shell 700. In the connected state, the positioning protrusions 790 correspond one by one to the positioning recesses 820.

[0136] refer to Figure 2 Foam is also formed between the bottom of the second shell 700 and the protective shell 800. The foam is an insulating member. In addition to providing insulation protection, the foam can also be deformed under the contact between the second shell 700 and the protective shell 800. Without causing deformation of the power supply line 783, it provides limiting support for the power supply line 783 and reduces the gap around the power supply line 783.

[0137] refer to Fig.12 In some embodiments of the present application, a threading portion 850 is also provided on the protective housing 800 to facilitate the connection of the power supply line 783.

[0138] The present application also proposes a wire controller, including a first shell 200, a second shell 700 and a power board 600. A display unit 100 is connected to one side of the first shell 200 for displaying temperature information or switch light operation instructions.

[0139] The second shell 700 is detachably connected to the other side of the first shell 200 , and an installation cavity is formed between the first shell 200 and the second shell 700 , and the power board 600 is disposed in the installation cavity.

[0140] The bottom of the second shell 700 connects the power board 600 and the power supply line 783 via the conductive part 730 . The conductive part 730 is configured to provide power to the power board 600 and is detachably connected to the first shell 200 .

[0141] The conductive part 730 can serve as an intermediate conductor for the connection between the power supply line 783 and the power board 600. The conductive part 730 can avoid problems such as too large connection gap, poor moisture-proof and dust-proof effects, etc. caused by directly passing through the second shell 700 to connect to the power board 600 when power is supplied.

[0142] Specifically, the conductive portion 730 may be disposed in the following manners.

[0143] Method 1: The conductive part 730 is a copper column structure, which is inserted into the bottom of the second shell 700 by interference fit. The two ends of the conductive part 730 extend from the second shell 700 respectively. The power supply line 783 is connected to one end of the conductive part 730, and the power board 600 is connected to the other end of the conductive part 730. Then, the conductive part 730 can realize the electrical connection between the power board 600 and the power supply line 783.

[0144] A claw may be provided at each end of the conductive portion 730 , and the claw may be opened or closed to achieve connection with the power supply line 783 and the terminal on the power board 600 .

[0145] Mode 2: The outer side of the conductive part 730 is configured to be connected to the power supply line 783 through the first crimping part 781 , and the inner side of the conductive part 730 is configured to be detachably connected to the power board 600 through the second crimping part 760 .

[0146] Specifically, both ends of the conductive portion 730 are formed with internal threads, and the first crimping portion 781 and the second crimping portion 760 are both connection screws.

[0147] During installation, the first crimping part 781 connects one end of the power supply line 783 to the conductive part 730, and the second crimping part 760 connects the terminal on the power board 600 to the conductive part 730. Then, through the conversion of the conductive part 730, the power supply line 783 can supply power to the power board 600.

[0148] The wire controller realizes the switching through the conductive part 730, which can prevent the power supply line 783 from directly passing through the second shell 700 into the installation cavity, reduce the generation of connection analysis, and prevent external moisture or dust from entering the installation cavity.

[0149] The wire controller involved in the present application has a conductive part 730 connected to the bottom of the second shell 700, the outer side of the conductive part 730 is connected to the power supply line 783 through the first crimping part 781, and the inner side of the conductive part 730 is connected to the power board 600 through the first crimping part 781, so that the power supply line 783 in the wire controller and the power board 600 are connected. The power supply line 783 is not directly connected to the installation cavity, which is conducive to avoiding the formation of gaps at the wiring, so that external humid gas or external water enters the installation cavity, affecting the service life of components such as the power board 600;

[0150] In addition, an overlapping outer edge 220 is formed on the peripheral side of the first shell 200. In the installed state, the first shell 200 covers the outer side of the second shell 700, and a sealing ring 300 is arranged between the first shell 200 and the second shell 700, so as to further improve the sealing of the wire controller, facilitate installation, and improve the overall waterproof and moisture-proof performance of the wire controller.

[0151] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0152] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
