Furthermore, the repeated moving and rotating of the indoor and outdoor units during production increases unnecessary movement and reduces production efficiency. Utility Model Content

[0003] The main purpose of this utility model is to propose an air conditioner that designs the connection between the flexible pipe and the indoor / outdoor unit of the air conditioner as a detachable structure that can be quickly separated, thus taking into account both pre-installation efficiency and on-site flexibility.

[0004] To achieve the above objectives, the air conditioner proposed in this utility model includes:

[0005] Air conditioner indoor unit;

[0006] Air conditioner outdoor unit; and

[0007] A refrigerant hose assembly connects the indoor unit and the outdoor unit of an air conditioner. The refrigerant hose assembly includes a first refrigerant pipe group and a first electrical wire. The indoor unit and / or the outdoor unit of the air conditioner are provided with a connection end. The connection end has a second refrigerant pipe group corresponding to the first refrigerant pipe group and a second electrical wire corresponding to the first electrical wire. The first refrigerant pipe group and the second refrigerant pipe group are detachably connected, and the first electrical wire and the second electrical wire are detachably electrically connected.

[0008] In one embodiment, the refrigerant hose assembly further includes a first drain pipe, and the connecting end also has a second drain pipe corresponding to the first drain pipe, wherein the first drain pipe and the second drain pipe are detachably connected.

[0009] In one embodiment, the indoor unit and / or the outdoor unit of the air conditioner are further provided with a positioning bracket, and the second refrigerant pipe assembly, the second electrical wire and the second drain pipe are all detachably fixed to the positioning bracket.

[0010] In one embodiment, the first drain pipe and the second drain pipe are sealed together by a quick-connect pipe structure.

[0011] In one embodiment, the quick-connect structure is configured as a connecting valve head that connects the first drain pipe and the second drain pipe respectively.

[0012] In one embodiment, the quick-connect structure for water pipes is configured as a first drain connector and a second drain connector that achieve a sealed connection by axial locking, wherein the first drain connector is disposed on the first drain pipe and the second drain connector is disposed on the second drain pipe.

[0013] In one embodiment, the positioning bracket is provided with a water pipe slot, and the wall of the second drain pipe is fixedly engaged in the water pipe slot.

[0014] In one embodiment, the first refrigerant pipe assembly and the second refrigerant pipe assembly are sealed together by a refrigerant quick-connect structure.

[0015] In one embodiment, the first refrigerant pipe assembly is provided with a first refrigerant connector at the mating end, and the second refrigerant pipe assembly is provided with a second refrigerant connector. The refrigerant quick-connect structure is configured to achieve a sealed connection between the first refrigerant connector and the second refrigerant connector through axial locking.

[0016] In one embodiment, the positioning bracket is further provided with a connector mounting cavity, and the second refrigerant connector is installed in the connector mounting cavity.

[0017] In one embodiment, the indoor unit and / or the outdoor unit of the air conditioner are provided with an electrical connection box, and the first electrical wire and the second electrical wire are both electrically connected to the electrical connection box.

[0021] In one embodiment, one end of the refrigerant hose assembly is pre-installed with the outdoor unit of the air conditioner, and the other end is detachably connected to the indoor unit of the air conditioner.

[0022] This invention uses a refrigerant hose assembly as an intermediate carrier to achieve a detachable connection with the indoor and / or outdoor units of an air conditioner, solving problems related to production efficiency, packaging, and installation. Specifically, the refrigerant hose assembly is detachably connected to the indoor unit; or detachably connected to the outdoor unit; or detachably connected to both the indoor and outdoor units. Compared to previous methods where the refrigerant hose assembly was pre-installed as a single unit during production, at least one of the indoor and outdoor units can be processed separately during production.

Furthermore, at least one of the indoor and outdoor units can be packaged separately, reducing packaging complexity and volume. In addition, it expands the specific application scenarios. When it is impossible to move only one of the indoor and outdoor air conditioning units and place them on both sides of an obstacle (such as when the user installs the unit by drilling holes in the wall and cannot place the connecting pipe in the wall hole), the refrigerant hose assembly can be disassembled to remove the constraint between the indoor and outdoor air conditioning units and improve on-site flexibility.

[0047] In the design and production of air conditioning systems, refrigerant hose assemblies are pre-installed as a single unit by connecting the indoor and outdoor units during the production stage. They are packaged, transported, and even used by users when plugged in. All three are tightly connected and cannot be disassembled.

[0048] It has the following disadvantages:

[0049] 1. The indoor and outdoor units of the air conditioner need to be produced simultaneously, resulting in a long production line and complex material organization. In addition, the indoor and outdoor units need to be repeatedly moved and rotated during the production process, which increases unnecessary movements and reduces production efficiency.

[0050] 2. The internal and external packaging is integrated, resulting in a large packaging volume, inconvenience for production personnel to operate, and high labor intensity.

[0051] 3. It limits the usage scenarios. For example, if the user installs it by drilling a hole in the wall, the connecting pipe cannot be placed in the wall hole.

[0052] Therefore, this utility model proposes an air conditioner that designs the connection between the flexible pipe and the indoor / outdoor unit of the air conditioner as a detachable structure that can be quickly separated, taking into account both pre-installation efficiency and on-site flexibility.

[0053] Please see Figures 1 to 6 In one embodiment of the present invention, the air conditioner includes an indoor unit 10, an outdoor unit 20, and a refrigerant hose assembly 30. At least one end of the refrigerant hose assembly 30 is provided with a docking end 301. The indoor unit 10 and / or the outdoor unit 20 are provided with a connecting end 102. The refrigerant hose assembly 30 includes a first refrigerant pipe group 31 and a first electrical wire 32. The connecting end 102 has a second refrigerant pipe group 11 corresponding to the first refrigerant pipe group 31 and a second electrical wire 12 corresponding to the first electrical wire 32. The first refrigerant pipe group 31 and the second refrigerant pipe group 11 are detachably connected, and the first electrical wire 32 and the second electrical wire 12 are detachably electrically connected.

[0054] The technical solution of this utility model uses the refrigerant hose assembly 30 as an intermediate carrier to achieve flexible and detachable connection with the indoor unit 10 and the outdoor unit 20 of the air conditioner, solving the problems of production efficiency, packaging, and installation. Specifically, the refrigerant hose assembly 30 is detachably connected to the indoor unit 10; or the refrigerant hose assembly 30 is detachably connected to the outdoor unit 20; or the refrigerant hose assembly 30 is detachably connected to both the indoor unit 10 and the outdoor unit 20. Compared with the previous solution where the refrigerant hose assembly 30 was pre-connected to the indoor unit 10 and the outdoor unit 20 as a whole during the production stage, at least one of the indoor unit 10 and the outdoor unit 20 can be processed separately during the production stage. This reduces the length of the production line and the complexity of material organization, reduces the need for repeated handling during the production process, and improves production efficiency. Furthermore, at least one of the indoor unit 10 and the outdoor unit 20 can be packaged separately, reducing the complexity of the packaging process and the volume of the packaging. In addition, it expands the specific application scenarios. When it is impossible to move only one of the indoor unit 10 and the outdoor unit 20 and place them on both sides of an obstacle (such as when the user installs by drilling holes in the wall and cannot place the connecting pipe in the wall hole), the refrigerant hose assembly 30 can be disassembled to release the constraint between the indoor unit 10 and the outdoor unit 20 and improve on-site flexibility.

[0055] Reference Figures 2 to 4 In one embodiment, the refrigerant hose assembly 30 includes an external flexible protective sleeve 301 and a first refrigerant pipe group 31 (two refrigerant pipes) disposed within the flexible protective sleeve 301, and a set of electrical wires (including at least motor leads and sensor leads, which power the compressor, fan motor and other components of the outdoor unit 20 of the air conditioner, and transmit sensor data (such as temperature and pressure signals) and commands (such as power on / off and mode switching)).

[0056] In this embodiment, the refrigerant hose assembly 30 also includes a first drain pipe 33. In cooling mode, the indoor unit 10 of the air conditioner produces condensate (moisture in the air condenses on the evaporator surface). The drain pipe guides the condensate through the flexible refrigerant hose to the outdoor unit 20 of the air conditioner or directly discharges it outdoors.

[0057] Therefore, in the scheme of not setting the first drain pipe 33 in the refrigerant hose assembly 30, an alternative can be to set a water storage box at the bottom of the air conditioner indoor unit 10 or to set the second drain pipe 13 as an independent pipe, so that the condensate can be discharged directly to the outside through the independently set second drain pipe 13.

[0058] At least one end of the refrigerant hose assembly 30 is provided with a mating end 301, and the indoor unit 10 and / or outdoor unit 20 of the air conditioner are provided with a connecting end 102. The connecting end 102 refers to the interface portion fixed on the indoor unit 10 or the outdoor unit 20 of the air conditioner (including the refrigerant pipe interface and electrical interface corresponding to the refrigerant hose assembly 30), which is used to receive the mating end 301 of the refrigerant hose assembly 30 to achieve stable transmission of refrigerant and electrical signals. For example, the connecting end 102 may include a pre-installed copper pipe flare (refrigerant interface) and a quick-connect terminal (electrical interface). In this way, when the mating end 301 of the refrigerant hose assembly 30 is inserted into the connecting end 102 of the indoor unit 10 of the air conditioner, the refrigerant quick-connect valve automatically locks and seals, and the electrical terminal is anti-foolproof. The whole process does not require tools. During maintenance, the mating end 301 and the connecting end 102 can be separated by pressing the unlocking mechanism to achieve non-destructive disassembly of the refrigerant pipe and electrical wires.

[0059] The refrigerant hose assembly 30 can be connected to the indoor unit 10 and the outdoor unit 20 of the air conditioner in three ways: the refrigerant hose assembly 30 can be detachably connected to the indoor unit 10; or the refrigerant hose assembly 30 can be detachably connected to the outdoor unit 20; or the refrigerant hose assembly 30 can be detachably connected to both the indoor unit 10 and the outdoor unit 20.

[0060] Reference Figures 2 to 4 The following description uses the refrigerant hose assembly 30 as an example, which is detachably connected to the indoor unit 10 of the air conditioner and to the outdoor unit 20 of the air conditioner.

[0061] Combination Figure 6 The indoor unit 10 of the air conditioner includes a housing 101 and components disposed within the housing 101 (refer to a general basic structure); the housing 101 is rectangular and made of sheet metal (or other materials). The back panel of the housing 101 (or other locations) is provided with a wire harness outlet groove 103 (rectangular through groove) along the height direction of the housing 101. The wire harness outlet groove 103 is located near the left side (or right side) of the back panel. An air intake grille is provided on the right side (if the back panel is divided into 4 rectangular areas from top to bottom along the left and right direction, the area where the rectangular through groove is located occupies 1 / 4, and the air intake grille occupies 3 / 4).

[0062] In one embodiment, the refrigerant hose assembly 30 has a docking module at the connection end 102. For example, the first refrigerant hose group 31 and the first electrical wire 32 are both connected to the docking module. The docking module includes an integrated refrigerant quick-connect valve and electrical terminals wrapped with anti-slip rubber. Correspondingly, a connection module is provided at the connection end 102. The connection module is pre-installed with a copper tube flare (refrigerant interface) and quick-connect terminals (electrical interface). Thus, quick insertion and removal can be achieved by matching the docking module and the connection module. The docking module and the connection module are integrated plug and socket components.

[0063] Reference Figures 2 to 4In this embodiment, the first refrigerant pipe group 31, the first electrical wire 32, the refrigerant hose assembly 30 and the first drain pipe 33 extend beyond the flexible protective sleeve 301. The extended portions are respectively provided with corresponding quick-release connectors, and the electrical wires are detachably connected (e.g., by using keyway plugs to ensure a unique docking direction; or in some solutions, spring pin contacts are used to reduce contact resistance).

[0064] Combination Figure 5 To facilitate the fixing of the wiring harness of the indoor unit 10 and its connection with the wiring harness in the refrigerant hose assembly 30, a positioning bracket 40 is provided at the wiring harness outlet groove 103. The second refrigerant pipe assembly 11, the second electrical wire 12, and the second drain pipe 13 can all be detachably fixed to the positioning bracket 40. In other solutions, a snap-fit ​​structure can also be used to fix the wiring harness.

[0065] Understandably, the first electrical wire 32 can also be fixed on the positioning bracket 40.

[0066] The positioning bracket 40 is provided with a fixing structure 43 for connecting to the indoor unit 10 of the air conditioner. In this embodiment, the fixing structure 43 is configured as a fixing groove, which allows screws to be fastened and concealed. In other embodiments, the fixing structure may also be configured as a snap-fit ​​or the like.

[0067] Specifically, the first drain pipe 33 and the second drain pipe 13 are sealed together by a quick-connect pipe structure 34.

[0068] In one embodiment, the quick-connect structure 34 is configured to connect the docking valve head 131 of the first drain pipe 33 and the second drain pipe 13 respectively.

[0069] In one embodiment, the quick-connect structure 34 is configured as a first drain connector and a second drain connector to achieve a sealed connection by axial locking. The first drain connector is located on the first drain pipe 33, and the second drain connector is located on the second drain pipe 13.

[0070] To facilitate the fixing of the drain pipe, the positioning bracket 40 is provided with a pipe slot 41, and the pipe wall of the second drain pipe 13 is fixed in the pipe slot 41. Compared with using metal clamps (such as flat steel or ABS material) to wrap the pipe wall, the fixing is more convenient.

[0071] Specifically, the first refrigerant pipe assembly 31 is provided with a first refrigerant connector 311 at the docking end 301, the second refrigerant pipe assembly 11 is provided with a second refrigerant connector 111, and the refrigerant quick-connect structure 35 is configured to achieve a sealed connection between the first refrigerant connector 311 and the second refrigerant connector 111 through axial locking.

[0072] The detachable connection of the refrigerant pipe is achieved by mechanical sealing through an axial locking mechanism (such as a rotary buckle or spring lock); or some solutions use a refrigerant quick-connect valve with self-sealing function to prevent refrigerant leakage during disassembly.

[0073] Combination Figure 6 To facilitate the fixing of the second refrigerant connector 111, the positioning bracket 40 is also provided with a connector mounting cavity 42, in which the second refrigerant connector 111 is installed. The positioning bracket 40 is configured as a positioning box, and the positioning box has a mounting groove that axially matches the contour of the second refrigerant connector 111. The bottom of the mounting cavity has an opening for the pipe body of the second refrigerant pipe assembly 11 to pass through. The water pipe clamping groove 41 is located on the outer edge of the positioning box and clamps the outer wall of the second drain pipe 13 to fix the second drain pipe 13.

[0074] Reference Figures 2 to 4 Specifically, the indoor unit 10 of the air conditioner is provided with an electrical connection box 50, and the electrical connection box 50 is provided with quick-connect terminals. The first electrical wire 32 and the second electrical wire 12 are both electrically connected to the quick-connect terminals.

[0075] An electrical connection box 50 (with an internal circuit connector) is provided on the back plate of the positioning bracket 40 or the housing 101. The electrical connection box 50 is equipped with quick-connect terminals (posts, locking rings), and the second electrical wire 12 can be pre-connected to the electrical connection box 50.

[0076] This allows the indoor unit 10 and outdoor unit 20 of the air conditioner to be manufactured, packaged, and transported separately. Using this solution simplifies production organization and allows for more flexible assembly of indoor and outdoor units. During production and assembly, it reduces the need for additional handling and rotating of the indoor unit 10 and outdoor unit 20, while also reducing packaging volume for easier operation, lowering worker workload, and significantly improving assembly efficiency. This also makes it suitable for a wider range of application scenarios.

[0077] Because they can be set up separately, if it is necessary to separate the indoor unit 10 and the outdoor unit 20 of the air conditioner, for example, on both sides of a wall, the indoor unit 10 and the outdoor unit 20 can be moved separately, reducing the difficulty of installation. For example, if the outdoor unit 20 is placed outdoors or on a balcony, you only need to pull the refrigerant hose assembly 30 into the room and connect the wiring harness inside the refrigerant hose assembly 30 to the wiring harness of the indoor unit 10.

[0078] During production, the indoor unit 10 of the air conditioner can be produced and packaged separately (with the pipe cover 14 pre-assembled during production), while the outdoor unit 20 of the air conditioner and the refrigerant hose assembly 30 can be produced and packaged together. Before use, the user can connect the connecting pipe to the indoor unit 10 of the air conditioner and then use it normally.

[0079] Of course, the indoor unit 10, outdoor unit 20, and refrigerant hose assembly 30 can also be pre-assembled at the factory. The disadvantage is that the packaging is still a single unit. The advantage is that the indoor and outdoor units can be produced separately and then connected before final packaging, saving some extra handling and rotation of the indoor and outdoor units, thus improving production efficiency and reducing labor intensity.

[0080] Specifically, in the docking direction, the electrical connector box 50 is located above the positioning bracket 40. When the electrical connector box 50 is located above the positioning bracket 40, a natural "top-down" wiring harness routing can be formed, reducing the cable bending radius and avoiding insulation wear or signal interference caused by excessive bending; in addition, the high position of the electrical connector box 50 forms a "suspended" structure with the positioning bracket 40 below, allowing the wiring harness to naturally expand and contract with temperature changes, avoiding stress concentration.

[0081] Reference Figure 1 Specifically, the indoor unit 10 of the air conditioner is also equipped with a piping cover 14, which at least covers the connection point between the connecting end 102 and the docking end 301. The piping cover 14 is fixed to the casing 101 of the indoor unit 10 of the air conditioner by a snap-fit ​​structure, which serves to protect the connecting components. The piping cover 14 must at least cover the connection point between the connecting end 102 (the interface fixed to the indoor unit 10 of the air conditioner) and the docking end 301 (the detachable interface of the refrigerant hose assembly 30). The piping cover 14 wraps around or surrounds the docking area of ​​components such as refrigerant pipes and electrical wires, such as covering the copper pipe flared joint, electrical terminal plug points, and drain pipe groove 41, to prevent external impacts from causing the interface to loosen or deform (such as refrigerant pipe welding points breaking or electrical terminals falling off), and to prevent dust, moisture, insects, etc. from entering the connection point, reducing the risk of short circuits or blockages.

[0082] The indoor unit 10 and outdoor unit 20 of the air conditioner are connected by a refrigerant hose assembly 30. This allows for easy installation by individual users. The refrigerant hose assembly 30 connects the indoor heat exchanger of the indoor unit 10 and the outdoor heat exchanger of the outdoor unit 20, and refrigerant is pre-filled into the refrigerant circuit before the unit leaves the factory. Therefore, when users install the unit themselves, they only need to fix the indoor unit 10 and outdoor unit 20 separately, without needing to install refrigerant pipes or add refrigerant, thus reducing installation difficulty and enabling individual installation.

[0083] When the air conditioner is configured as a split-type air conditioner (the outdoor unit 20 and the indoor unit 10 are connected by a refrigerant hose assembly), the compressor can be further located in the indoor unit 10. This reduces the weight of the outdoor unit 20, making it easier for users to move the outdoor unit 20 to a suitable installation location, reducing installation difficulty and labor costs, especially in areas with high labor costs, enabling individual installation. Correspondingly, to reduce noise, the compressor in the indoor unit 10 undergoes noise reduction treatment, such as filling it with noise-reducing materials and setting up a buffer structure to reduce compressor vibration transmission.

[0084] In addition, since the compressor is located in the indoor unit 10, casters are provided at the bottom of the indoor unit 10 to facilitate user movement within the room (see figure). This eliminates the need for users to laboriously move the heavy indoor unit 10; they can simply push it to move it. This is especially convenient for users who frequently need to adjust the air conditioner's position or move it between rooms. When the air conditioner is not in use, users can push it to a corner or storage room, thus saving indoor space.

[0085] Furthermore, the design of the moving wheels also includes a locking mechanism, such as a brake device, to prevent the air conditioner from sliding on its own when it is not needed.

[0086] Furthermore, considering that different floor materials (such as carpet, wood flooring, and tile) exert varying degrees of friction on the casters, which may affect the smoothness of movement, casters suitable for various floor materials are provided.

[0087] Furthermore, since one end of the refrigerant hose assembly 30 is pre-installed with the outdoor unit 20 and the other end is detachably connected to the indoor unit 10, if it is necessary to separate the indoor unit 10 and the outdoor unit 20, for example, on opposite sides of a wall, the indoor unit 10 and the outdoor unit 20 can be moved separately, reducing the difficulty of installation. For example, if the outdoor unit 20 is placed outdoors or on a balcony, it is only necessary to pull the refrigerant hose assembly 30 into the room and connect the wiring harness inside the refrigerant hose assembly 30 to the wiring harness of the indoor unit 10.

[0088] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
