Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and more particularly to a wall-mounted air conditioner. Background Technology

[0002] With the development of air conditioning technology, air conditioning products are constantly being updated and replaced. From the evolution of air conditioning models, the earliest air conditioning model was the integrated window air conditioner. Now, split air conditioners are the mainstream model. Floor-standing air conditioners and wall-mounted air conditioners are two important branches of today's split air conditioners. As the name suggests, floor-standing air conditioners are air conditioners with indoor units in the shape of columns and installed on the ground, while wall-mounted air conditioners are air conditioners with indoor units suspended on the wall by components such as back panels and brackets.

[0003] In wall-mounted air conditioner indoor units of relevant technologies, the heat exchanger is usually arranged inside the casing along the length of the indoor unit. However, to meet the design trend of lightweight and miniaturized wall-mounted air conditioner indoor units, the length space of the casing along the length of the indoor unit is relatively small. This results in limited space for the heat exchanger along the length of the indoor unit, leading to a smaller heat exchange area, lower energy efficiency, and difficulty in meeting the high energy efficiency design requirements of wall-mounted air conditioners. Utility Model Content

[0004] This application discloses a wall-mounted air conditioner that can increase the length and heat exchange area of ​​the indoor heat exchanger while meeting the requirements of miniaturized indoor unit design, thereby improving the energy efficiency of the wall-mounted air conditioner.

[0005] To achieve the above objectives, this application discloses a wall-mounted air conditioner, which includes an indoor unit and an outdoor unit;

[0006] The indoor unit includes:

[0007] A housing having an air inlet and an air outlet;

[0008] The base is disposed inside the housing, and a heat exchange air duct is formed between the base and the housing. The heat exchange air duct is connected to the air inlet and the air outlet respectively. The base is provided with a pipe groove on the rear side in the width direction of the housing, and the pipe groove is connected to the heat exchange air duct.

[0009] An indoor heat exchanger is disposed on the base and located within the heat exchange duct, and the indoor heat exchanger extends along the length of the casing.

[0010] A heat exchange fan is rotatably mounted on the base and located in the heat exchange duct. The heat exchange fan is located on the leeward side of the indoor heat exchanger. The heat exchange fan is used to drive indoor air into the heat exchange duct through the air inlet and exchange heat through the indoor heat exchanger. The heated indoor air is then discharged through the air outlet.

[0011] A drive motor is mounted on the base and located within the heat exchange duct. The drive motor is connected to the heat exchange fan and is used to drive the heat exchange fan to rotate.

[0012] An electrical control box is mounted on the base and electrically connected to the drive motor. The electrical control box is located on the front side of the indoor heat exchanger in the width direction of the casing.

[0013] The refrigerant piping connects to the indoor heat exchanger and is arranged along the length of the casing within the heat exchange duct. The refrigerant piping includes inlet and outlet piping sections that pass through the pipe groove for connecting to the outdoor unit.

[0014] Piping pressure plate, which is connected to the base, is used to limit the inlet and outlet piping sections in the pipe groove;

[0015] The through-tube groove has a first slot and a second slot. The first slot penetrates the rear sidewall of the base in the width direction of the housing, and the second slot penetrates the first sidewall of the base in the length direction of the housing and extends along the width direction of the housing to communicate with the first slot.

[0016] The piping pressure plate includes:

[0017] The first pressure plate portion is connected to the rear side wall of the base and seals the first slot.

[0018] The second pressure plate is connected at an angle to the first pressure plate and is connected to the first side wall of the base. The second pressure plate covers the second slot.

[0019] In the wall-mounted air conditioner provided in this application embodiment, by setting the electrical control box on the front side of the indoor heat exchanger in the width direction of the casing, and the through-pipe groove on the base penetrating the side wall of the base in the length direction of the casing, the refrigerant pipeline can approach the first side wall of the base in the length direction of the casing. Thus, within the limited length space of the base, a certain length space can be provided for the indoor heat exchanger in the length direction of the casing, so that the indoor heat exchanger can make full use of the length space of the base. This allows the length of the indoor heat exchanger to be increased while meeting the requirements of miniaturized indoor unit design, thereby increasing the heat exchange area of ​​the indoor heat exchanger and improving the energy efficiency of the wall-mounted air conditioner.

[0020] As an optional implementation, in the embodiments of this application, one of the first pressure plate portion and the rear side wall is provided with a first snap-fit ​​portion, and the other of the first pressure plate portion and the rear side wall is provided with a first slot extending along the length direction of the housing, and the first snap-fit ​​portion is engaged and fixed with the first slot.

[0021] This design allows the first pressure plate and the rear wall of the base to be connected and fixed by a snap-fit ​​method, which is relatively simple and facilitates the assembly of the first pressure plate and the rear wall of the base.

[0022] As an optional implementation, in an embodiment of this application, the first card slot includes:

[0023] The first sub-slot passes through the rear sidewall or the side of the first pressure plate portion in the width direction of the housing.

[0024] The second sub-slot and the first sub-slot are arranged along the height direction of the housing, and the second sub-slot does not penetrate the rear side wall or the side of the first pressure plate in the width direction of the housing. The second sub-slot has a first groove wall in the width direction of the housing, and the first groove wall and the bottom wall of the first sub-slot face opposite directions.

[0025] The first latching part includes:

[0026] The first sub-clamping part extends along the length of the housing and is disposed in the first sub-slot, abutting against the bottom wall of the first sub-slot.

[0027] The second sub-clamping part and the first sub-clamping part are arranged along the height direction of the housing. The second sub-clamping part includes a first part and a second part connected at an angle. The first part is connected to the first pressure plate part or the rear side wall and extends along the length direction of the housing. The first part passes through the second sub-clamping groove and abuts against the first groove wall. The second part passes through the second sub-clamping groove to abut against the rear side wall or the first pressure plate part in the length direction of the housing.

[0028] In the above structural design, on the one hand, in the width direction of the housing, the obstruction of the first sub-slot wall to the first sub-slot can be reduced, making it easier to insert the first sub-slot into the first sub-slot; on the other hand, the mutual abutment between the first sub-slot and the bottom wall of the first sub-slot, as well as the mutual abutment between the first part and the first slot wall, can prevent the first pressure plate from moving in the width direction of the housing. At the same time, the mutual abutment between the second part and the rear side wall of the base, and the mutual abutment between the first pressure plate and the rear side wall of the base, can prevent the first pressure plate from moving in the length direction of the housing. This can improve the installation stability of the first pressure plate on the base, thereby improving the anti-drop performance of the piping pressure plate.

[0029] As an optional implementation, in an embodiment of this application, the first slot has an inlet side, the first latching part is inserted into the first slot from the inlet side, the inlet side is provided with a first guide slope, the first guide slope is used to guide the first latching part into the first slot; and / or,

[0030] The first latching part has a first insertion end, and the first latching part is inserted into the first slot from the first insertion end. The end of the first insertion end is provided with a second guide slope, which is used to guide the first latching part into the first slot.

[0031] By setting a first guide slope and a second guide slope, the first buckle can be more easily inserted into the first slot during the process of inserting the first buckle into the first slot, thus achieving the snap-fit ​​fixation of the two.

[0032] As an optional implementation, in an embodiment of this application, one of the second pressure plate portion and the first side wall is provided with a second buckle portion, and the other of the second pressure plate portion and the first side wall is provided with a second slot extending along the length direction of the housing, and the second buckle portion is engaged and fixed with the second slot.

[0033] This design allows the second pressure plate and the first side wall of the base to be connected and fixed by a snap-fit ​​method, which is relatively simple and facilitates the assembly of the second pressure plate and the first side wall of the base.

[0034] As an optional implementation, in an embodiment of this application, the second latching part includes a third part and a fourth part connected at an angle. The third part is connected to the second pressure plate part or the first side wall and extends along the width direction of the housing. In the length direction of the housing, the third part abuts against the groove wall of the through-tube groove or the second pressure plate part, and the fourth part passes through the second latching groove.

[0035] The second pressure plate or the first side wall is also provided with a baffle. The baffle and the second buckle are arranged along the height direction of the housing, and the third part and the baffle respectively abut against the groove wall of the through pipe groove on both sides of the housing length direction, or respectively abut against the second pressure plate on both sides of the housing length direction.

[0036] In the above structural design, the cooperation between the fourth part and the second slot can restrict the movement of the second pressure plate in the width direction of the housing. At the same time, the mutual abutment between the third part and the first side wall of the base, the mutual abutment between the baffle and the first side wall of the base, or the mutual abutment between the third part and the second pressure plate, and the mutual abutment between the baffle and the second pressure plate can prevent the second pressure plate from moving in the length direction of the housing. This can improve the installation stability of the second pressure plate on the base, thereby improving the anti-drop performance of the piping pressure plate.

[0037] Furthermore, compared to the fourth part having an extension portion that extends along the width direction of the housing and is spaced apart from the third part, the method of restricting the movement of the second pressure plate portion in the length direction of the housing by having the third part and the extension portion respectively abut against the groove wall of the through-tube groove on both sides in the length direction of the housing, or by having the third part and the extension portion respectively abut against both sides of the second pressure plate portion in the length direction of the housing, is more convenient to insert into the second slot and cooperate with the second slot because the size of the fourth part is smaller than the size of the extension portion in the width direction of the housing. This achieves the second snap-fit ​​portion and the second slot snap-fit ​​fixation.

[0038] As an optional implementation, in the embodiments of this application, the surface abutting the third part is defined as a first surface, the first surface including a third guide ramp, which is disposed corresponding to the second slot in the width direction of the housing, and the third guide ramp is used to guide the fourth part to move into the second slot; and / or,

[0039] The fourth part has a second insertion end, which is inserted into the second slot. The end of the second insertion end is provided with a fourth guide slope, which is used to guide the fourth part into the second slot.

[0040] By setting the first guide slope and the second guide slope, during the process of inserting the second buckle into the second slot, the fourth part can be guided to move into the second slot with the help of the guidance and direction of the third guide slope, and the fourth part can be guided into the second slot with the help of the guidance and direction of the fourth guide slope. This makes it easier for the fourth part to be inserted into the second slot, thus achieving the snap-fit ​​and fixation of the second buckle and the second slot.

[0041] As an optional implementation, in an embodiment of this application, the first surface further includes a plane parallel to the width direction of the housing, the plane connecting the groove wall of the second slot and the third guide slope, and the plane abutting against the third portion.

[0042] The planar design avoids sharp corners at the connection between the third guide slope and the groove wall of the second slot, increases the contact area between the third part and the first side wall, and provides a more stable limiting effect in the length direction of the housing.

[0043] As an optional implementation, in an embodiment of this application, the second latching portion further includes a fifth portion that is angularly connected to the third portion, and the fifth portion is spaced apart from the fourth portion in the width direction of the housing;

[0044] In the width direction of the housing, the fourth part abuts against the groove wall of the second slot near the fifth part;

[0045] The third part is connected to the surface of the second pressure plate portion facing the first pressure plate portion via the fifth part, so that the second pressure plate portion abuts against the first sidewall in the width direction of the housing; or...

[0046] The third part is connected to the surface of the first sidewall located within the through-tube groove via the fifth part, so that the first sidewall abuts against the second pressure plate portion in the width direction of the housing.

[0047] By providing a fifth part, the third part is connected to the surface of the second pressure plate facing the first pressure plate, allowing the second pressure plate to abut against the first side wall in the width direction of the housing. Simultaneously, the fourth part abuts against the groove wall of the second slot near the fifth part, restricting the movement of the second pressure plate in the width direction of the housing. Alternatively, the third part is connected to the surface of the first side wall located within the through-tube groove, allowing the first side wall to abut against the second pressure plate in the width direction of the housing. Simultaneously, the fourth part abuts against the groove wall of the second slot near the fifth part. This eliminates the need to use the fourth part to abut against the two groove walls of the second slot in the width direction of the housing to restrict the movement of the second pressure plate in the width direction of the housing. This allows the size of the second slot in the width direction of the housing to be larger than the size of the fourth part in the width direction of the housing, facilitating the insertion and fixing of the fourth part into the second slot.

[0048] As an optional implementation, in an embodiment of this application, in the height direction of the housing, the through-tube groove includes a first groove portion and a second groove portion that are connected. The first groove portion is closer to the top of the housing than the second groove portion. In the width direction of the housing, the depth of the first groove portion is less than the depth of the second groove portion. The second slot is formed on the groove wall of the second groove portion. This increases the elasticity of the groove wall at the location of the second slot, facilitating the engagement and fixation of the second latching part with the second slot.

[0049] In addition, since the depth of the first tank section is smaller than that of the second tank section, compared to the method where the depths of the first and second tank sections are the same, the space occupied by the pipe trench on the base can be reduced, so that the base can have more space to install the indoor heat exchanger. This facilitates the assembly of the indoor heat exchanger and improves installation efficiency. Attached Figure Description

[0087] The indoor unit of a wall-mounted air conditioner typically includes components such as a casing, an indoor heat exchanger, an electrical control box, and refrigerant piping. The indoor heat exchanger, refrigerant piping, and electrical control box are usually arranged along the length of the casing.

[0088] Currently, with the development of air conditioning technology, and considering that wall-mounted air conditioner indoor units are almost always suspended indoors, their size is relatively small to facilitate installation. However, in order to meet the miniaturization design requirements of wall-mounted air conditioner indoor units, the installation space along the length of the unit's casing is limited. Furthermore, because the casing needs to accommodate components such as the indoor heat exchanger, refrigerant piping, and electrical control box along its length, the space available for installing the indoor heat exchanger is limited. This results in a smaller heat exchanger area, lower energy efficiency, and higher power consumption, making it difficult to meet the high energy efficiency design requirements of wall-mounted air conditioners.

[0089] In view of this, the present application provides a wall-mounted air conditioner that can achieve a miniaturized indoor unit design while increasing the length and heat exchange area of ​​the indoor heat exchanger, thereby improving the energy efficiency of the wall-mounted air conditioner.

[0090] The technical solutions of some 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.

[0091] This application discloses a wall-mounted air conditioner that primarily uses a compressor, condenser, expansion valve, and evaporator to perform a refrigeration cycle. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0092] The compressor compresses the refrigerant gas at a low temperature and low pressure, discharging it as a high temperature and high pressure 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.

[0093] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout this cycle, the wall-mounted air conditioner regulates the temperature of the indoor space.

[0094] The wall-mounted air conditioner provided in this application embodiment can have various implementation forms, such as... Figure 1 As shown, Figure 1 This is an exemplary specific implementation of the wall-mounted air conditioner provided in the embodiments of this application. The wall-mounted air conditioner 100 provided in the embodiments of this application includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 is installed in an indoor space, and the indoor unit 10 can be connected to the outdoor unit 20 installed in an outdoor space through a pipe 30.

[0095] In this design, outdoor unit 20 refers to the portion of the refrigeration cycle that includes the compressor and outdoor heat exchanger, while indoor unit 10 refers to the portion of the refrigeration cycle that includes the indoor heat exchanger. An expansion valve can be provided in either the indoor or outdoor unit. The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger functions as a condenser, the wall-mounted air conditioner 100 functions as a heater in heating mode; when the indoor heat exchanger functions as an evaporator, the wall-mounted air conditioner 100 functions as a cooler in cooling mode.

[0096] Please see Figure 2 , Figure 2This is an exemplary structural diagram of a wall-mounted air conditioner indoor unit provided in an embodiment of this application. The indoor unit 10 provided in this embodiment of the application can be a wall-mounted unit or other structure. The indoor unit 10 includes a housing 11, which forms the overall appearance of the indoor unit 10.

[0097] For example, such as Figure 2 As shown, the housing 11 has a top and a bottom, with the top and bottom of the housing 11 being opposite ends. The distance from the top to the bottom of the housing 11 is the height direction of the housing 11, such as the vertical direction in Figure 2. The housing 11 also has a left and a right side, with the left and right sides of the housing 11 being opposite ends. The distance from the left to the right side of the housing 11 is the length direction of the housing 11, such as... Figure 2 The left and right directions; the housing 11 has a front side and a rear side, the front side and the rear side of the housing 11 are opposite sides, and the direction from the front side to the rear side of the housing 11 is the thickness direction of the housing 11, for example Figure 2 The front and back directions in the middle.

[0098] The casing 11 is located at the top of the room or in the upper space of the room, with the front of the casing 11 facing the user and the rear of the casing 11 facing the wall.

[0099] In some embodiments, such as Figure 2 and Figure 3 As shown, the indoor unit 10 provided in this application embodiment also includes a base 12, which is disposed inside the housing 11, and a heat exchange air duct 111 is formed between the base 12 and the housing 11. The heat exchange air duct 111 can be used to accommodate various functional devices of the wall-mounted air conditioner indoor unit 10, such as the indoor heat exchanger 13, heat exchange fan 14 and drive motor 15 mentioned later.

[0100] In some embodiments, such as Figure 3 and Figure 4 As shown, the housing 11 also has an air inlet 112 and an air outlet 113 that communicate with the heat exchange air duct 111. The air inlet 112 is located at the top of the housing 11, and the air outlet 113 is located at the bottom of the housing 11. Alternatively, the air outlet 113 is located on the front side of the housing 11 and near the bottom of the housing 11, that is, the air outlet 113 is located on the lower front side of the housing 11.

[0101] Please see Figure 3 and Figure 4 The indoor unit 10 provided in this application embodiment also includes an indoor heat exchanger 13, which is disposed on the base 12 and located in the heat exchange air duct 111. The indoor heat exchanger 13 is used to exchange heat with indoor air entering the heat exchange air duct 111 through the air inlet 112 to form air conditioning air to meet the user's cooling or heating needs.

[0102] The air conditioning can provide cold air, hot air, or even air at room temperature.

[0103] Optionally, the indoor heat exchanger 13 is positioned near the air inlet 112.

[0104] like Figure 4 As shown, the indoor unit 10 provided in this embodiment of the application also includes a heat exchange fan 14. The heat exchange fan 14 is disposed on the base 12 and located in the heat exchange duct 111 and on the leeward side of the indoor heat exchanger 13. The heat exchange fan 14 is used to drive indoor air into the heat exchange duct 111 through the air inlet 112 and exchange heat through the indoor heat exchanger 13. The heat-exchanged indoor air is discharged through the air outlet 113, that is, the heat-exchanged air flows into the room through the air outlet 113, thereby realizing the temperature regulation of the indoor space.

[0105] Optionally, the heat exchange fan 14 may be a cross-flow fan, and the rotation axis of the heat exchange fan 14 extends along the length of the housing 11.

[0106] Optionally, the heat exchange fan 14 is positioned near the air outlet 113.

[0107] In some embodiments, the indoor unit 10 provided in this application further includes a drive motor 15, which is disposed on the base 12 and located in the heat exchange duct 111. The drive motor 15 and the heat exchange fan 14 are arranged along the length of the casing and connected to the heat exchange fan 14 so that the drive motor 15 can be used to drive the heat exchange fan 14 to rotate. Thus, under the drive of the heat exchange fan 14, indoor air enters the heat exchange duct 111 from the air inlet 112 and exchanges heat with the indoor heat exchanger 13. The air after heat exchange by the indoor heat exchanger 13, such as cooled cold air or heated hot air, is blown into the indoor space through the air outlet 113 to change the air temperature of the indoor space, such as lowering or raising the air temperature of the indoor space.

[0108] In some embodiments, such as Figure 4 and Figure 5 As shown, the indoor unit 10 provided in this application embodiment also includes an electrical control box 16, which is disposed on the base 12 and electrically connected to the drive motor 15 to provide power, control, and protection for the drive motor 15.

[0109] The electrical control box 16 can be located inside the heat exchange duct.

[0110] Optionally, the electrical control box 16 may include a box body and an electrical control board, with the box body mounted on the base 12 and the electrical control board mounted in the center and electrically connected to the drive motor 15.

[0111] In some embodiments, such as Figure 5 and Figure 6 As shown, the indoor unit 10 provided in this embodiment of the application also includes a refrigerant pipeline 17. The refrigerant pipeline 17 is connected to the indoor heat exchanger 13 and is arranged along the length of the casing. The refrigerant pipeline 17 has inlet and outlet pipe sections 171, which are inserted into the pipe groove 114 and used to connect to the outdoor unit, so that the indoor unit and the outdoor unit are connected through the refrigerant pipeline 17, thereby realizing the exchange of heat.

[0112] Specifically, the inlet and outlet piping section 171 includes a first inlet and outlet piping section 171a and a second inlet and outlet piping section 171b. The first inlet and outlet piping section 171a connects to the outdoor heat exchanger, and the second inlet and outlet piping section 171b connects to the compressor. In cooling mode, high-temperature, high-pressure gaseous refrigerant is discharged from the compressor and enters the outdoor heat exchanger (e.g., the outdoor condenser) of the outdoor unit. The refrigerant dissipates heat in the outdoor condenser and gradually cools into a high-pressure liquid state. The high-pressure liquid refrigerant is throttled and depressurized through the expansion valve, becoming a low-temperature, low-pressure liquid / gas mixture. The low-temperature refrigerant enters the refrigerant pipeline 17 and the indoor heat exchanger 13 (e.g., the indoor evaporator) sequentially through the first inlet and outlet piping section 171a. After absorbing indoor heat in the indoor evaporator, the low-temperature refrigerant evaporates into a low-pressure gaseous state. The low-pressure gaseous refrigerant returns to the compressor sequentially through the refrigerant pipeline 17 and the second inlet and outlet piping section 171b, completing the cycle.

[0113] In cooling mode, the four-way valve changes the refrigerant flow direction, turning the indoor heat exchanger 13 into an indoor condenser and the outdoor heat exchanger into an outdoor evaporator. High-temperature, high-pressure gaseous refrigerant is discharged from the compressor and flows directly to the indoor heat exchanger 13 (e.g., the indoor condenser) through the second inlet / outlet piping section 171b. The refrigerant releases heat in the indoor condenser (e.g., heating the room) and condenses into a high-pressure liquid. The high-pressure liquid refrigerant is then depressurized by the expansion valve, becoming a low-temperature, low-pressure liquid / gas mixture. The low-temperature refrigerant sequentially enters the outdoor heat exchanger (e.g., the outdoor evaporator) through refrigerant piping 17 and the first inlet / outlet piping section 171a. In the outdoor evaporator, the low-temperature refrigerant absorbs heat from the outside environment and evaporates into a low-pressure gas. The low-pressure gaseous refrigerant returns from the outdoor evaporator to the compressor, completing the cycle.

[0114] In some embodiments, the indoor unit provided in this application also includes a piping pressure plate 18, which is connected to the base 12 and is used to limit the inlet and outlet piping sections 171 in the pipe groove 114, thereby fixing and limiting the inlet and outlet piping sections 171, and preventing after-sales installation inconvenience caused by misalignment of the inlet and outlet piping sections 171, or causing the inlet and outlet piping sections 171 to collide with other parts, thereby damaging the pipeline and affecting product quality.

[0115] In some embodiments, such as Figure 6 and Figure 7As shown, the electrical control box 16 can be located on the front side of the indoor heat exchanger 13 in the width direction of the casing. The through-tube groove 114 has a first groove 1141 and a second groove 1142 that are connected. The first groove 1141 passes through the rear sidewall 12a of the base 12 in the width direction of the casing, and the second groove 1142 passes through the first sidewall 12b of the base 12 in the length direction of the casing. The second groove 1142 also passes through the rear side of the first sidewall 12b in the width direction of the casing, and the second groove 1142 extends along the width direction of the casing to communicate with the first groove 1141. The piping clamp 18 includes a first clamping plate portion 18a and a second clamping plate portion 18b. The first clamping plate portion 18a is connected to the rear side wall 12a of the base and covers the first slot 1141 to prevent the inlet and outlet piping sections 171 from leaving the pipe groove 114 through the first slot 1141. The second clamping plate portion 18b is connected to the first clamping plate portion 18a at an angle and is connected to the first side wall 12b of the base. The second clamping plate portion 18b covers the second slot 1142 to prevent the inlet and outlet piping sections 171 from leaving the pipe groove 114 through the second slot 1142, thereby limiting the inlet and outlet piping sections 171 in the pipe groove 114.

[0116] By placing the electrical control box 16 on the front side of the indoor heat exchanger 13 in the width direction of the casing, the electrical control box 16 no longer occupies the space of the heat exchange air duct in the length direction of the casing, freeing up a certain amount of space. Furthermore, the pipe groove 114 on the base 12 passes through the first side wall 12b of the base 12 in the length direction of the casing. This can be seen as the pipe groove 114 moving towards the first side wall 12b of the base 12 in the length direction of the casing, allowing the refrigerant pipe 17 to approach the first side wall 12b of the base 12 in the length direction of the casing, while still maintaining the inlet and outlet distribution. Pipe segment 171 can be inserted into pipe groove 114, thereby providing a certain length of space for indoor heat exchanger 13 in the length direction of the casing within the limited length space of base 12. This allows indoor heat exchanger 13 to make full use of the length space of base 12, thereby achieving miniaturization of indoor unit design. For example, without increasing the length of casing in its length direction, the length of indoor heat exchanger 13 can be increased, thereby increasing the heat exchange area of ​​indoor heat exchanger 13. This can improve the energy efficiency of wall-mounted air conditioner and save electricity.

[0117] For example, with the design of this application, the length ratio of the indoor heat exchanger 13 to the casing can be as high as 84% ​​or more, such as 84%, 84.5%, 85%, 85.6%, 86%, 86.4%, 86.8%, 87%, 87.5%, 88%, 88.7%, 89%, 89.3%, or 90%, etc.

[0118] In addition, since the pipe groove 114 has a second groove 1142 that penetrates the first side wall 12b of the base 12, and the second groove 1142 penetrates the rear side of the first side wall 12b in the width direction of the housing, during assembly, the inlet and outlet pipe sections can enter the pipe groove 114 not only from the first groove 1141, but also from the second groove 1142, which facilitates the assembly of the pipe groove 114 and helps to improve assembly efficiency.

[0119] In some embodiments, in the length direction of the casing, the second pressure plate portion 18b and the drive motor 15 (e.g., motor cover) are both flush with the first side wall 12b of the base 12. Thus, in the length direction of the casing, there can be only one second pressure plate portion 18b between the inlet and outlet pipe section 171 and the casing, thereby providing as much space as possible for the indoor heat exchanger 13, allowing the indoor heat exchanger 13 to be longer, and thus allowing the heat exchange area of ​​the indoor heat exchanger 13 to be larger. This can greatly improve the energy efficiency of the wall-mounted air conditioner and save electricity.

[0120] In some embodiments, the first pressure plate portion 18a and the second pressure plate portion 18b may be arranged at 90° or approximately 90°, in which case the piping pressure plate 18 may be or approximately an L-shaped component. It is understood that during the production process, process factors such as equipment precision and measurement errors may affect the actual molding effect of the housing, causing the included angle between the first pressure plate portion 18a and the second pressure plate portion 18b to be approximately 90°, for example, 88°, 89°, 91°, or 92°.

[0121] It is understood that in other embodiments, the angle between the first pressure plate portion 18a and the second pressure plate portion 18b can be other angles, such as 80°, 85°, etc.

[0122] Optionally, the first pressure plate portion 18a and the second pressure plate portion 18b are integrally formed. This eliminates the need for joints between the first pressure plate portion 18a and the second pressure plate portion 18b, resulting in a stronger and more durable overall structure for the piping pressure plate 18; it also reduces assembly steps, saving time and costs.

[0123] In some embodiments, such as Figure 8 and Figure 9As shown, one of the first pressure plate portion 18a and the rear side wall 12a of the base is provided with a first latching portion 181, and the other of the first pressure plate portion 18a and the rear side wall 12a of the base is provided with a first slot 121 extending along the length direction of the housing. That is, when the first pressure plate portion 18a is provided with the first latching portion 181, the rear side wall 12a of the base is provided with the first slot 121 extending along the length direction of the housing; and when the first pressure plate portion 18a is provided with the first slot 121 extending along the length direction of the housing, the rear side wall 12a of the base is provided with the first latching portion 181. The first latching portion 181 is inserted into the first slot 121 along the length direction of the housing and is engaged and fixed with the first slot 121.

[0124] The connection and fixation between the first pressure plate 18a and the rear side wall 12a of the base are achieved by using a snap-fit ​​method. The connection method is relatively simple and facilitates the assembly between the first pressure plate 18a and the rear side wall 12a of the base.

[0125] In some embodiments, the first slot 121 includes a first sub-slot 1211 and a second sub-slot 1212 arranged along the height direction of the housing, and the first latching portion 181 includes a first sub-latching portion 181a and a second sub-latching portion 181b arranged along the height direction of the housing. The first sub-latching portion 181a is latched and fixed to the first sub-slot 1211, and the second sub-latching portion 181b is latched and fixed to the second sub-slot 1212. This arrangement allows the first pressure plate portion 18a and the rear sidewall 12a of the base to be latched and fixed through the engagement of multiple first latching portions 181 with multiple first slots 121, thereby improving the connection stability between the first pressure plate portion 18a and the rear sidewall 12a of the base.

[0126] The following will describe in detail the specific structure of the first buckle 181 and the first slot 121, taking the first pressure plate 18a as an example where the first buckle 18a is provided with the first buckle 181 and the rear side wall 12a of the base is provided with the first slot 121. When the first pressure plate 18a is provided with the first slot 121 and the rear side wall 12a of the base is provided with the first buckle 181, the specific structure of the first buckle 181 and the first slot 121 can be referred to the description when the first pressure plate 18a is provided with the first buckle 181 and the rear side wall 12a of the base is provided with the first slot 121.

[0127] In some embodiments, combined with Figures 9 to 12As shown, the first sub-slot 1211 of the first slot 121 penetrates the rear sidewall 12a of the base on the side of the housing width direction. The second sub-slot 1212 does not penetrate the rear sidewall 12a of the base on the side of the housing width direction. The second sub-slot 1212 has a first groove wall (not shown) on the housing width direction. The first groove wall and the bottom wall of the first sub-slot 1211 have opposite orientations. For example, the first groove wall faces the front of the housing, and the bottom wall of the first sub-slot 1211 faces the rear of the housing. The first sub-clamping part 181a extends along the length direction of the housing. For example, the first sub-clamping part 181a is a plate-like structure extending along the length direction of the housing. The first sub-clamping part 181a is disposed in the first sub-slot 1211 and abuts against the groove wall of the first sub-slot 1211. The second sub-clamping part 181b includes a first part 1811 and a second part 1812 connected at an angle. The first part 1811 is connected to the first pressure plate part 18a and extends along the length direction of the housing. The first part 1811 passes through the second sub-clamping groove 1212 and abuts against the first groove wall. The second part 1812 passes through the second sub-clamping groove 1212 to abut against the rear side wall 12a of the base in the length direction of the housing.

[0128] Understandably, the second sub-clamping part 181b can be engaged in the second sub-clamping slot 1212 by its own elastic deformation.

[0129] If neither the first sub-slot 1211 nor the second sub-slot 1212 penetrates the side of the rear sidewall 12a of the base 12 in the width direction of the housing, both the first sub-slot 181a and the second sub-slot 181b include a first part 1811 and a second part 1812 connected at an angle. Since the second part 1812 is set at an angle to the first part 1811, the size of the position of the second part 1812 in the width direction of the housing is usually larger than the size of the first part 1811. In order to ensure that the second part 1812 can... The first part 1811 can pass through the first sub-slot 1211 to abut against the rear side wall 12a of the base in the length direction of the housing. In the width direction of the housing, the size of the first sub-slot 1211 is greater than or equal to the size of the position where the second part 1812 is located. Therefore, in the width direction of the housing, the size of the first sub-slot 1211 is greater than the size of the first part 1811. When each of the first parts 1811 is respectively inserted into the first sub-slot 1211 and the second sub-slot 1212, there is a possibility that the first part 1811 may move along the width direction of the housing.

[0130] Therefore, this application, by having the first sub-slot 1211 penetrate the rear sidewall 12a of the base in the width direction of the housing, and the second sub-slot 1212 not penetrate the rear sidewall 12a of the base in the width direction of the housing, and by making the first sub-clamping part 181a, which cooperates with the first sub-slot 1211, a plate-like structure extending along the length direction of the housing, and the second sub-clamping part 181b, which cooperates with the second sub-slot 1212, including a first part 1811 and a second part 1812 connected at an angle, can, on the one hand, reduce the obstruction of the first sub-clamping part 181a by the groove wall of the first sub-slot 1211 in the width direction of the housing, thus facilitating the insertion of the first sub-clamping part 181a. 1a is inserted into the first sub-slot 1211; on the other hand, the mutual abutment between the first sub-slot 181a and the bottom wall of the first sub-slot 1211, and the mutual abutment between the first part 1811 and the first slot wall, can prevent the first pressure plate part 18a from moving in the width direction of the housing. At the same time, the mutual abutment between the second part 1812 and the rear side wall 12a of the base 12, and the mutual abutment between the first pressure plate part 18a and the rear side wall 12a of the base, can prevent the first pressure plate part 18a from moving in the length direction of the housing. This can improve the installation stability of the first pressure plate part 18a on the base 12, thereby improving the anti-drop performance of the piping pressure plate 18.

[0131] In some embodiments, the first part 1811 and the second part 1812 may be set at 90° or approximately 90°. It is understood that during the production process, process factors such as equipment accuracy and measurement errors may affect the actual molding effect of the box, so that the included angle between the first part 1811 and the second part 1812 may be approximately 90°, such as 88°, 89°, 91° or 92°.

[0132] It is understood that in other embodiments, the angle between the first part 1811 and the second part 1812 may be other angles, such as 80°, 85°, etc.

[0133] In some embodiments, there may be two second sub-clamping parts 181b, with a first sub-clamping part 181a located between the two second sub-clamping parts 181b. Correspondingly, there may be two second sub-slots 1212, with a first slot 121 located between the two second sub-slots 1212. The two second sub-clamping parts 181b are respectively engaged and fixed with the corresponding second sub-slots 1212, thereby further improving the connection stability between the first pressure plate part 18a and the base 12.

[0134] As one embodiment, the first slot 121 has an inlet side, and the first latching part 181 is inserted into the first slot 121 from the inlet side. The inlet side is provided with a first guide slope 1213. For example, in the insertion direction of the first latching part 181 into the first slot 121, the size of the first slot 121 in the width direction and / or height direction of the housing is reduced to form the first guide slope 1213 on the inlet side. The first guide slope 1213 is used to guide the first latching part 181 into the first slot 121.

[0135] The first guide slope 1213 is provided so that when the first latching part 181 is inserted into the first slot 121, it first contacts the first guide slope 1213. The first guide slope 1213 can play a guiding role, so that the first latching part 181 can be guided to be inserted into the first slot 121, thereby allowing the first latching part 181 to be smoothly inserted into the first slot 121.

[0136] In another embodiment, the first latching part 181 has a first insertion end. Specifically, the first insertion end is formed at one end of the second part 1812 facing away from the first part 1811. The first latching part 181 is inserted into the first slot 121 from the first insertion end. The end of the first insertion end is provided with a second guide slope 1813. For example, in the insertion direction of the first latching part 181 into the first slot 121, the size of the second part 1812 in the width direction and / or height direction of the housing is reduced to form the second guide slope 1813 at the first insertion end. The second guide slope 1813 is used to guide the first latching part 181 into the first slot 121.

[0137] The second guide slope 1813 is provided so that when the first latching part 181 is inserted into the first latching groove 121, the second guide slope 1813 first contacts the groove wall of the first latching groove 121. The second guide slope 1813 can play a guiding and guiding role, so that the first latching part 181 can be guided to be inserted into the first latching groove 121, thereby allowing the first latching part 181 to be smoothly inserted into the first latching groove 121.

[0138] In another embodiment, a first guide slope 1213 is provided on the entrance side of the first slot 121, and a second guide slope 1813 is provided on the first insertion end of the first latching part 181. Both the first guide slope 1213 and the second guide slope 1813 are used to guide the first latching part 181 into the first slot 121. The provision of the first guide slope 1213 and the second guide slope 1813 enables the first latching part 181 to be inserted into the first slot 121 more easily during the process of inserting the first latching part 181 into the first slot 121, thereby achieving the snap-fit ​​fixation of the two.

[0139] In some embodiments, such as Figures 15 to 17 As shown, one of the second pressure plate portion 18b and the first side wall 12b of the base is provided with a second latching portion 182, and the other of the second pressure plate portion 18b and the first side wall 12b of the base is provided with a second slot 122 extending along the length direction of the housing. That is, when the second pressure plate portion 18b is provided with the second latching portion 182, the first side wall 12b of the base 12 is provided with the second slot 122 extending along the length direction of the housing; and when the second pressure plate portion 18b is provided with the second slot 122 extending along the length direction of the housing, the first side wall 12b of the base is provided with the second latching portion 182. The second latching portion 182 is inserted into the second slot 122 along the length direction of the housing and is engaged and fixed with the second slot 122.

[0140] The connection and fixation between the second pressure plate part 18b and the first side wall 12b of the base are achieved by using a snap-fit ​​method. The connection method is relatively simple and facilitates the assembly between the second pressure plate part 18b and the first side wall 12b of the base.

[0141] The following will describe in detail the specific structure of the second latching part 182 and the second slot 122, taking the second pressure plate part 18b as an example where the second latching part 18b is provided with the second latching part 182 and the first side wall 12b of the base is provided with the second latching part 122. When the second pressure plate part 18b is provided with the second slot 122 and the first side wall 12b of the base is provided with the second latching part 182, the specific structure of the second latching part 182 and the second slot 122 can be referred to the description when the second pressure plate part 18b is provided with the second latching part 182 and the first side wall 12b of the base is provided with the second slot 122.

[0142] In some embodiments, such as Figure 16 and Figure 17 As shown, the second latching part 182 includes a third part 1821 and a fourth part 1822 connected at an angle. The third part 1821 is connected to the second pressure plate part 18b and extends along the width direction of the housing. In the length direction of the housing, the third part 1821 abuts against the groove wall of the through-tube groove 114. The fourth part 1822 passes through the second latching groove 122 to restrict the movement of the second pressure plate part 18b in the width direction of the housing. The second pressure plate part 18b is also provided with a baffle 183. The baffle 183 and the second latching part 182 are arranged along the height direction of the housing. The third part 1821 and the baffle 183 abut against the groove wall of the through-tube groove 114 on both sides in the length direction of the housing to restrict the movement of the second pressure plate part 18b in the length direction of the housing.

[0143] In the above structural design, the cooperation between the fourth part 1822 and the second slot 122 can restrict the movement of the second pressure plate part 18b in the width direction of the housing. At the same time, the mutual abutment between the third part 1821 and the first side wall 12b of the base 12, and the mutual abutment between the baffle 183 and the first side wall 12b of the base 12, can prevent the second pressure plate part 18b from moving in the length direction of the housing. This can improve the installation stability of the second pressure plate part 18b on the base 12, thereby improving the anti-drop performance of the piping pressure plate 18.

[0144] Furthermore, compared to the fourth part 1822 having an extension portion that extends along the width direction of the housing and is spaced apart from the third part 1821, the method of restricting the movement of the second pressure plate part 18b in the length direction of the housing by having the third part 1821 and the extension portion respectively abut against the groove wall of the through-tube groove 114 on both sides of the housing length direction is more convenient to insert into the second slot 122 and cooperate with the second slot 122, thereby realizing the second snap-fit ​​part 182 and the second slot 122 snap-fit ​​and fix.

[0145] Understandably, the fourth part 1822 can be engaged in the second slot 122 by relying on the elastic deformation of the third part 1821.

[0146] In some embodiments, such as Figures 17 to 20 As shown, the third part 1821 and the fourth part 1822 can be set at 90° or approximately 90°. Understandably, during the production process, process factors such as equipment precision and measurement errors may affect the actual molding effect of the box, so that the included angle between the third part 1821 and the fourth part 1822 can be approximately 90°, such as 88°, 89°, 91° or 92°, etc.

[0147] It is understood that in other embodiments, the angle between the third part 1821 and the fourth part 1822 may be other angles, such as 80°, 85°, etc.

[0148] In some embodiments, there may be two baffles 183, with the second latching portion 182 located between the two baffles 183. By utilizing the two baffles 183 to abut against the first sidewall 12b of the base respectively, the second pressure plate portion 18b can be better limited in the length direction of the housing, further reducing the possibility of the second pressure plate portion 18b moving along the length direction of the housing.

[0149] In some embodiments, the second latching portion 182 further includes a fifth portion 1823 that is angularly connected to the third portion 1821. The fifth portion 1823 is spaced apart from the fourth portion 1822 in the width direction of the housing. The third portion 1821 is connected to the surface of the second pressure plate portion 18b facing the first pressure plate portion 18a via the fifth portion 1823, so that the second pressure plate portion 18b can abut against the first side wall 12b of the base in the width direction of the housing. At the same time, in the width direction of the housing, the fourth portion 1822 abuts against the groove wall of the second slot 122 near the fifth portion 1823 to restrict the movement of the second pressure plate portion 18b in the width direction of the housing.

[0150] By setting the fifth part 1823, the third part 1821 is connected to the surface of the second pressure plate part 18b facing the first pressure plate part 18a through the fifth part 1823, so that the second pressure plate part 18b can abut against the first side wall 12b in the width direction of the housing. At the same time, the fourth part 1822 abuts against the groove wall of the second slot 122 near the fifth part 1823 to restrict the movement of the second pressure plate part 18b in the width direction of the housing. Therefore, it is not necessary to use the fourth part 1822 to restrict the movement of the second pressure plate part 18b in the width direction of the housing by using the two groove walls of the second slot 122 in the width direction of the housing. As a result, the size of the second slot 122 in the width direction of the housing can be larger than the size of the fourth part 1822 in the width direction of the housing, so that the fourth part 1822 can be inserted into the second slot 122 and fixed in place.

[0151] In some embodiments, a clearance ramp 1824 is provided at the connection between the third part 1821 and the fifth part 1823. This reduces the space occupied by the third part 1821 and the fifth part 1823 in the pipe groove 114 and avoids the inlet and outlet piping sections.

[0152] In some embodiments, the third part 1821 and the fifth part 1823 may be set at 90° or approximately 90°. It is understood that during the production process, process factors such as equipment accuracy and measurement errors may affect the actual molding effect of the box, so that the included angle between the third part 1821 and the fifth part 1823 may be approximately 90°, such as 88°, 89°, 91° or 92°.

[0153] It is understood that in other embodiments, the angle between the third part 1821 and the fifth part 1823 may be other angles, such as 80°, 85°, etc.

[0154] In this application, for ease of description, such as Figure 20 and Figure 21As shown, the surface where the first sidewall 12b abuts against the third portion 1821 is defined as the first surface 123. It is understood that the above definition is merely for ease of description and should not be construed as limiting the scope of protection of this application.

[0155] In one embodiment, the first surface 123 includes a third guide slope 1231. In the width direction of the housing, the third guide slope 1231 corresponds to the second slot 122 and is used to guide the fourth part 1822 to move into the second slot 122. Thus, during the process of inserting the second latching part 182 into the second slot 122, the third guide slope 1231 guides the fourth part 1822 to move into the second slot 122, allowing the fourth part 1822 to be smoothly inserted into the second slot 122.

[0156] In another embodiment, the fourth part 1822 has a second insertion end, which is inserted into the second slot 122. The end of the second insertion end is provided with a fourth guide slope 1825. For example, in the insertion direction of the fourth part 1822 into the second slot 122, the size of the fourth part 1822 in the width and / or height direction of the housing is reduced to form the fourth guide slope 1825 at the second insertion end. The fourth guide slope 1825 is used to guide the fourth part 1822 into the second slot 122.

[0157] The fourth guide slope 1825 is provided so that when the fourth part 1822 is inserted into the second slot 122, the fourth guide slope 1825 first contacts the slot wall of the second slot 122. The fourth guide slope 1825 can play a guiding and guiding role, so that the fourth part 1822 can be guided to be inserted into the second slot 122, thereby allowing the fourth part 1822 to be smoothly inserted into the second slot 122.

[0158] In another embodiment, the first surface 123 includes a third guide slope 1231. In the width direction of the housing, the third guide slope 1231 is provided corresponding to the second slot 122, and the third guide slope 1231 is used to guide the fourth part 1822 to move to the second slot 122; and the end of the second insertion end is provided with a fourth guide slope 1825, which is used to guide the fourth part 1822 to be inserted into the second slot 122.

[0159] Thus, during the process of inserting the second latching part 182 into the second slot 122, the fourth part 1822 can be guided to move into the second slot 122 with the help of the guiding and guiding effect of the third guide slope 1231, and the fourth part 1822 can be guided into the second slot 122 with the help of the guiding and guiding effect of the fourth guide slope 1825. This makes it easier for the fourth part 1822 to be inserted into the second slot 122, thereby achieving the snap-fit ​​and fixation of the second latching part 182 and the second slot 122.

[0160] In some embodiments, the first surface 123 further includes a plane 1232 parallel to the width direction of the housing, the plane 1232 connecting the groove wall of the second slot 122 and the third guide slope 1231, and the plane 1232 abutting against the third portion 1821.

[0161] The plane 1232 can prevent sharp corners from forming at the connection between the third guide slope 1231 and the groove wall of the second slot 122, and increase the contact area between the third part 1821 and the first side wall 12b, which can play a more stable limiting role in the length direction of the housing.

[0162] In some embodiments, such as Figure 22 As shown, in the height direction of the housing, the through-tube groove 114 includes a first groove portion 114a and a second groove portion 114b that are connected. The first groove portion 114a is closer to the top of the housing than the second groove portion 114b. In the width direction of the housing, the depth of the first groove portion 114a is smaller than the depth of the second groove portion 114b. The second slot 122 is formed on the groove wall of the second groove portion 114b. This increases the elasticity of the groove wall at the location of the second slot 122, making it easier for the second latching part 182 to engage and fix with the second slot 122.

[0163] In addition, since the depth of the first tank portion 114a is smaller than the depth of the second tank portion 114b, compared to the method where the depths of the first tank portion 114a and the second tank portion 114b are the same, the space occupied by the through-tube groove 114 on the base can be reduced, so that the base can have more space to install the indoor heat exchanger, thereby facilitating the assembly of the indoor heat exchanger and improving installation efficiency.

[0164] In some embodiments, such as Figure 23 As shown, the piping pressure plate 18 (e.g., the first pressure plate part 18a) is provided with a weight reduction groove 1814 to save materials and reduce the weight of the piping pressure plate 18, thereby achieving a lightweight design and enabling faster injection molding.

[0165] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0166] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
