Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a drainage structure and an air conditioner. Background Art

[0002] Air conditioner drainage is a key concern during design and operation. Traditional air conditioner drainage systems often involve complex piping layouts and sealing structures, which can be challenging to install and maintain. For example, the air conditioner drain pipe typically requires a secure connection to the housing of the indoor or outdoor unit to ensure smooth drainage of condensed water.

[0003] In the prior art, a pipe joint structure is provided to facilitate the connection between the drain pipe and the casing. However, the pipe joint structure in the prior art is often directly inserted into the casing by utilizing its own elasticity and clamped with the inner side of the casing. This clamping method often requires a large installation thrust and is inconvenient to install. Utility Model Content

[0011] In one embodiment, a radially protruding width of the engaging section along the first end is greater than a radially extending width of the notch section along the first end.

[0012] In one embodiment, a radial width of the spiral clamping portion along the first end gradually increases in a direction approaching the clamping portion.

[0013] In one embodiment, the spiral clamping rib has a second guide surface at one end away from the clamping portion, and the distance from the second guide surface to the mounting hole gradually increases in a direction away from the clamping portion.

[0014] In one embodiment, the clamping portion further includes an elastic portion extending along the circumferential direction of the first end, and the spiral clamping rib is provided on the outer circumferential side of the elastic portion.

[0018] In one embodiment, the drainage structure also includes an annular seal, the outer peripheral surface of the pipe joint is provided with an annular abutment portion spaced apart from the clamping portion, the annular abutment portion and the clamping portion are arranged on opposite sides of the casing, and the annular seal is clamped between the annular abutment portion and the casing.

[0019] The utility model also provides an air conditioner, comprising the drainage structure as described above.

[0020] In one embodiment, the air conditioner includes an air conditioner indoor unit, an air conditioner outdoor unit, a flexible connection component and an outdoor drain pipe, the flexible connection component connects the air conditioner indoor unit and the air conditioner outdoor unit, the flexible connection component includes a sleeve, and a flexible refrigerant pipe and an indoor drain pipe arranged in the sleeve, the indoor drain pipe discharges condensed water in the air conditioner indoor unit to the air conditioner outdoor unit, the air conditioner outdoor unit includes the casing, and the outdoor drain pipe is connected to the pipe joint.

The water outlet can effectively reduce the water outlet height of the pipe joint, thereby reducing the possibility of water remaining on the chassis.

[0025] A first guide surface is provided on a side of the clamping portion facing away from the end surface of the first end, extending helically along the circumference of the first end. During actual installation, the end of the first guide surface closest to the first end extends into the mounting hole along with the first end portion, thereby causing the first guide surface to slide and abut against the circumference of the mounting hole. Then, the pipe joint is rotated axially along the mounting hole, causing the first guide surface to slide relative to the circumference of the mounting hole. Under the guidance of the first guide surface, the first end is rotated and engaged into the mounting hole until the clamping portion is completely screwed into the housing, thereby engaging with the edge of the mounting hole to prevent the pipe joint from being dislodged from the mounting hole. In other words, under the guidance of the first guide surface, the rotational motion of the pipe joint relative to the mounting hole is converted into axial insertion motion of the pipe joint into the mounting hole, thereby eliminating the need to directly press the pipe joint into the mounting hole by utilizing its own elasticity to engage with the inner edge of the mounting hole. This reduces the installation thrust required during installation of the pipe joint and facilitates installation of the pipe joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] The present invention provides a drainage structure for an air conditioner, comprising an outdoor unit 100 and an indoor unit. Flexible refrigerant pipes are connected to the indoor and outdoor units 100, respectively. The air conditioner can be a split-type air conditioner for easy user installation. The flexible refrigerant pipes connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit 100, with refrigerant injected into the refrigerant circuit before the device leaves the factory. Thus, when users install the device themselves, they only need to secure the indoor and outdoor units 100 separately, eliminating the need to assemble the flexible refrigerant pipes or inject refrigerant. This reduces installation complexity and facilitates user-friendly installation.

[0042] Furthermore, the compressor of this split-type air conditioner, which is user-friendly and easy to install, can be installed inside the indoor air conditioner, thereby reducing the weight of the outdoor air conditioner 100 and facilitating its installation outdoors. Accordingly, to reduce the noise generated by the compressor, a noise reduction structure is required for the compressor. However, the present invention is not limited to this. In other embodiments, the air conditioner of the present invention can also be a conventional split-type air conditioner or an integrated air conditioner.

[0043] The air conditioner also includes a flexible connection component, which includes a flexible refrigerant pipe and a sleeve mounted on the refrigerant pipe. Since there are generally two flexible refrigerant pipes to form a refrigerant circuit, the sleeve is mounted on the two flexible refrigerant pipes to form a whole, which facilitates the connection between the air conditioner indoor unit and the air conditioner outdoor unit 100.

[0044] The flexible connection assembly also includes an indoor drain pipe and connecting wires, which connect the indoor and outdoor air conditioner units 100, respectively. The flexible refrigerant pipe, indoor drain pipe, and connecting wires are all threaded through the casing, forming a single unit. This further facilitates the connection between the indoor and outdoor air conditioner units 100. The casing can also be configured as a wire structure, which is wrapped around the outer circumference of the refrigerant pipe, indoor drain pipe, and connecting wires to form the casing.

[0045] The air conditioner also includes an outdoor drain pipe connected to the housing 1 of the outdoor unit 100. This allows condensed water generated by the indoor unit to drain into the outdoor unit 100 through the indoor drain pipe, and then drains the condensed water from the outdoor unit 100 out of the air conditioner through the outdoor drain pipe. To facilitate the installation of the outdoor drain pipe and the housing 1, a pipe joint 11 is fixedly mounted on the housing 1 and sealed therewith. The outdoor drain pipe connection pipe joint 11 is located at one end outside the housing 1, thereby achieving a sealed connection between the outdoor drain pipe and the housing 1. The end of the pipe joint 11 located inside the housing 1 is used to connect to the indoor drain pipe or the interior of the housing 1, thereby draining water from the outdoor unit 100. To reduce the accumulation of condensed water in the outdoor unit 100, the housing 1 includes a chassis 104. The pipe joint 11 is mounted on the chassis 104 or at a location within the housing 1 near the chassis 104. In other embodiments, the pipe joint 11 can also be mounted at other locations within the housing 1. In other embodiments, the pipe joint 11 can also be installed on the housing 1 of the air conditioner indoor unit, and the indoor drainage pipe is connected to the pipe joint 11 to drain the air conditioner indoor unit. The following description takes the drainage structure provided on the air conditioner outdoor unit 100 as an example.

[0046] The indoor drain pipe discharges the condensed water in the indoor unit of the air conditioner into the casing 1 of the outdoor unit 100 of the air conditioner, and then the outdoor drain pipe discharges the condensed water in the casing 1. However, the discharge path of condensed water in the air-conditioning outdoor unit 100 is not restricted. For example, the indoor drain pipe can discharge the condensed water in the air-conditioning indoor unit to the outdoor heat exchanger in the air-conditioning outdoor unit 100 to assist the outdoor heat exchanger in dissipating heat in the cooling mode of the air conditioner, and then drip onto the chassis 104 of the outdoor unit casing 1, and then flow to the outdoor drain pipe through the chassis 104; it can also be directly discharged to the chassis 104 of the outdoor unit casing 1, and then flow to the outdoor drain pipe through the chassis 104. At this time, the pipe joint 11 is directly connected to the interior of the casing 1; the indoor drain pipe can also be directly connected to the outdoor drain pipe, so that it does not stay in the internal space of the casing 1, and the condensed water is directly discharged through the outdoor drain pipe. At this time, the pipe joint 11 is directly connected to the indoor drain pipe, or is connected to the indoor drain pipe through a connecting pipe; that is, as long as the condensed water in the air-conditioning indoor unit can pass through the casing 1, it is not necessary to make the condensed water in the air-conditioning indoor unit stay in the casing 1.

[0047] See also Figures 1 to 6 In one embodiment of the present invention, the drainage structure includes:

[0048] The housing 1 is provided with a mounting hole 101, and the periphery of the mounting hole 101 has a notch section 102 and a snap-fit ​​section 103 adjacent to the notch section 102; and

[0049] The pipe joint 11 has a first end 111 and a second end 112 remote from the first end 111. The first end 111 is provided with a water outlet 113 communicating with the inner circumference of the pipe joint 11. The circumference of the first end 111 is also provided with a clamping portion. The side of the clamping portion facing away from the end surface of the first end 111 is provided with a first guide surface 1141 extending spirally along the circumference of the first end 111. The second end 112 is used to connect to the drain pipe of the drainage structure.

[0050] The engaging portion extends from the notch section 102 into the mounting hole 101 , and under the guidance of the first guide surface 1141 , the first end 111 is rotated and engaged with the mounting hole 101 , and the engaging portion is at least engaged with the engaging section 103 .

[0051] Specifically, the housing 1 has a mounting hole 101 for inserting the pipe connector 11. The mounting hole 101 includes a notched section 102 and a snap-fit ​​section 103 adjacent to the notched section 102. Specifically, a mounting notch is provided along the circumference of the mounting hole 101, and the edge of the mounting hole 101 adjacent to the notch serves as the snap-fit ​​section 103. This notch partially enlarges the diameter of the mounting hole 101, thereby facilitating insertion of the first end 111. The first end 111 of the pipe connector 11 is mounted in the mounting hole 101, thereby connecting the pipe connector 11 to the interior of the housing 1. The second end 112 is connected to the air conditioner's drain pipe, thereby facilitating connection of the drain pipe to the air conditioner's housing 1. In order to facilitate the rapid installation of the pipe joint 11 in the mounting hole 101, a clamping portion is further provided on the circumferential side of the first end 111, and a first guide surface 1141 extending in a circumferential spiral along the first end 111 is provided on the side of the clamping portion facing away from the end face of the first end 111. The clamping portion is at least partially protruded from the circumferential side of the first end 111, thereby forming a first guide surface 1141 facing away from the end face of the first end 111 on the outer periphery of the circumferential side of the first end 111.

[0052] During actual installation, the end of the first guide surface 1141 closest to the first end 111 partially extends into the mounting hole 101 along with the first end 111, so that the first guide surface 1141 slides against the periphery of the mounting hole 101, and then, the pipe joint 11 is rotated along the axial direction of the mounting hole 101, so that the first guide surface 1141 slides relative to the periphery of the mounting hole 101, and under the guidance of the first guide surface 1141, the first end 111 is rotated and clamped into the mounting hole 101 until the clamping portion is completely screwed into the casing 1, so that the clamping portion is clamped with the edge of the mounting hole 101 to prevent the pipe joint 11 from falling out of the mounting hole 101. That is, under the guidance of the first guide surface 1141, the rotational movement of the pipe joint 11 relative to the mounting hole 101 is converted into the movement of the pipe joint 11 axially inserted into the mounting hole 101, so that there is no need to directly press the pipe joint 11 into the mounting hole 101 by utilizing its own elasticity to engage with the inner edge of the mounting hole 101, thereby reducing the installation thrust required for installing the pipe joint 11, thereby facilitating the installation of the pipe joint 11.

[0053] After installation is complete, the clamping portion is at least clamped to the clamping section 103. Generally, the clamping portion is clamped to the clamping section 103 to ensure stable installation of the pipe joint 11. However, sometimes, in order to adjust the drainage direction, the pipe joint 11 needs to be rotated by a certain angle, or the pipe joint 11 may be accidentally rotated, causing the clamping portion and the clamping section 103 to be misaligned. In this case, the clamping section may be clamped to the notch section 102. Therefore, preferably, the length of the clamping portion along the circumference of the first end 111 is greater than the length of the notch section 102 along the circumference of the first end 111, thereby ensuring the installation stability of the first end 111 and the housing 1 and reducing the possibility of the pipe joint 11 accidentally detaching from the housing 1.

[0054] Because the first end 111 is inserted into the mounting hole 101, the water-passing height of the pipe joint 11 is necessarily much greater than the height of the air conditioner chassis 104. Once water enters the air conditioner outdoor unit 100, some of the water will accumulate at the bottom of the casing 1, making it difficult to drain. This also creates the risk of leakage through the assembly gaps of the casing 1. Therefore, a water-passing port 113 is provided at the first end 111, communicating with the inner circumference of the pipe joint 11. This port 113 effectively lowers the water-passing height of the pipe joint 11, thereby reducing the possibility of water remaining on the chassis 104. To facilitate the processing of the port 113, in this embodiment, the port 113 is configured as a water-passing notch provided at the first end 111.

[0055] The first end 111 and the second end 112 are configured as the two connecting ends of the pipe joint 11. Therefore, the second end 112 is arranged away from the first end 111. However, the first end 111 and the second end 112 can be arranged relative to each other, in which case the pipe joint 11 is arranged as a straight cylinder. The first end 111 and the second end 112 can also be arranged not relative to each other, in which case the pipe joint 11 is arranged as a bent cylinder. The second end 112 is connected to the drain pipe. Therefore, under normal circumstances, the drain pipe is sleeved on the second end 112. Therefore, the outer peripheral surface of the second end 112 is provided with a rough section to increase the friction between the second end 112 and the drain pipe, ensuring a stable connection between the pipe joint 11 and the drain pipe.

[0056] In an embodiment of the present invention, the clamping portion includes a spiral clamping rib 114 that extends spirally along the circumference of the first end 111, and a first guide surface 1141 is provided on the side of the spiral clamping rib 114 that faces away from the end face of the first end 111. Specifically, the spiral clamping rib 114 extends spirally in a direction close to the end face of the first end 111, thereby forming the first guide surface 1141 on the side of the spiral clamping rib 114 that faces away from the end face of the first end 111, thereby guiding the axial movement of the first end 111 relative to the mounting hole 101. In this embodiment, the formation of the first guide surface 1141 by providing the spiral clamping rib 114 facilitates the processing of the first guide surface 1141. In other embodiments, the circumferential side wall of the first end 111 may be partially thickened, and a guide step may be formed on the side away from the end face of the first end 111, with the first guide surface 1141 formed on the side of the guide step facing away from the first end 111.

[0057] To ensure the stable connection between the clamping portion and the inner edge of the mounting hole 101, please refer to Figures 2 to 4 、 Figure 7 and Figure 8 In an embodiment of the present invention, a snap-fitting portion 1142 is provided at one end of the spiral snap-fitting rib 114 away from the end surface of the first end 111, and the snap-fitting portion 1142 abuts against the inner side of the snap-fitting section 103. Specifically, the snap-fitting portion 1142 is used to abut against the inner side of the snap-fitting section 103, thereby preventing the first end 111 from escaping from the mounting hole 101. In order to improve the abutment stability between the snap-fitting portion and the inner edge of the mounting hole 101, a side of the snap-fitting portion 1142 facing away from the end surface of the first end 111 forms an abutment surface parallel to the snap-fitting section 103, thereby increasing the abutment area between the snap-fitting portion and the snap-fitting portion 1142. Therefore, preferably, the snap-fitting portion 1142 is provided parallel to the snap-fitting section 103, and the circumferential length of the snap-fitting portion 1142 is greater than or equal to the circumferential length of the notch section 102.

[0058] To further facilitate the installation of the pipe joint 11, in an embodiment of the present invention, the radial width of the spiral clamping portion along the first end 111 gradually increases in a direction approaching the clamping portion 1142. Specifically, the radial width of the spiral clamping portion along the first end 111 gradually increases in a direction approaching the clamping portion 1142, so that the outer circumferential surface of the spiral clamping portion can also form a guide surface, thereby guiding the rotation of the spiral clamping portion relative to the mounting hole 101, and reducing the possibility of the spiral clamping portion being obstructed by the formation of steps due to local dimensional changes in the spiral clamping portion. Preferably, at least a portion of the outer circumferential surface of the spiral clamping portion is parallel to the outer circumferential surface of the first end 111, that is, at least a portion of the spiral clamping portion is configured with an arc segment.

[0059] Furthermore, the end of the spiral clamping rib 114 away from the engaging portion 1142 has a second guide surface 1143, and the distance between the second guide surface 1143 and the mounting hole 101 gradually increases in a direction away from the engaging portion 1142. Specifically, the second guide surface 1143 is provided at the end of the spiral clamping rib 114 away from the engaging portion 1142. That is, the second guide surface 1143 is the portion where the first end 111 extends into the mounting hole 101 during initial installation. Therefore, the distance between the second guide surface 1143 and the mounting hole 101 gradually increases in a direction away from the engaging portion 1142. Therefore, the second guide surface 1143 is configured as a flat surface, thereby further facilitating the first end 111 to extend into the mounting hole 101 and guiding the subsequent rotation of the pipe joint 11 relative to the mounting hole 101.

[0060] To reduce the possibility of the first end 111 being separated from the mounting hole 101, the radially protruding width of the engaging section 103 along the first end 111 is greater than the radially protruding width of the notch section 102 along the first end 111. Specifically, the radially protruding width of the engaging section 103 along the first end 111 is greater than the radially protruding width of the notch section 102 along the first end 111. In other words, the thickness of the engaging section 103 is greater than the depth of the notch section 102, thereby ensuring that the engaging section 103 will not be separated from the mounting hole 101 by the notch section 102.

[0061] When the radial width of the engaging section 103 along the first end 111 is greater than the radial width of the notch section 102 along the first end 111, the difficulty of inserting the first end 111 into the mounting hole 101 may be increased. Therefore, in order to facilitate the installation of the pipe joint 11, in the embodiment of the present invention, please refer to Figure 3 and Figure 4The clamping portion further includes an elastic portion 115 extending circumferentially along the first end 111, with a spiral clamping rib 114 disposed on the outer circumference of the elastic portion 115. The elastic portion 115 is elastically mounted to the first end 111, and the spiral clamping rib 114 is disposed on the outer circumference of the elastic portion 115. During installation, as the pipe joint 11 rotates, the edge of the mounting hole 101 presses against the elastic portion 115, causing the elastic portion 115 to retract the spiral clamping rib 114, thereby reducing the maximum diameter of the first end 111 and facilitating installation of the first end 111. After installation is complete, the elastic portion 115 rebounds, causing the spiral clamping rib 114 to engage with the inner side of the mounting hole 101, ensuring installation stability.

[0062] In other embodiments, the spiral clamping rib 114 can also be directly arranged on the outer peripheral side of the first end 111. In this case, the protruding height of the first end 111 is equal to or slightly less than or slightly greater than the depth of the notch section 102. At this time, the elasticity of the first end 111 itself can be facilitated to pass through the mounting hole 101.

[0063] To facilitate the periphery of the mounting hole 101 to press against the elastic portion 115, in the embodiment of the present invention, a third guide surface 1151 is further provided on the outer circumference of the elastic portion 115. The third guide surface 1151 is located on the side of the spiral clamping rib 114 away from the end surface of the first end 111, and the distance between the third guide surface 1151 and the mounting hole 101 gradually decreases in the direction approaching the clamping portion 1142.

[0064] When the first end 111 is rotated and inserted into the mounting hole 101 , the third guide surface 1151 slides against the periphery of the mounting hole 101 , so that the periphery of the mounting hole 101 presses the elastic portion 115 toward the inner periphery of the pipe joint 11 .

[0065] Specifically, the third guide surface 1151 is located on the side of the spiral clamping rib 114 away from the end face of the first end 111, and the distance from the third guide surface 1151 to the mounting hole 101 gradually decreases in the direction close to the clamping portion 1142, that is, the thickness of the elastic portion 115 gradually increases in the direction close to the clamping portion 1142, so that when the first end 111 is rotated to clamp into the mounting hole 101, the third guide surface 1151 slides and abuts against the periphery of the mounting hole 101, and the pressing strength between the two gradually increases, so that the periphery of the mounting hole 101 presses the elastic portion 115 toward the inner periphery of the pipe joint 11, thereby promoting the elastic portion 115 to drive the spiral clamping rib 114 to gradually retract, further facilitating the installation of the pipe joint 11.

[0066] To facilitate the processing of the first end 111, please refer to Figure 3 and Figure 4In an embodiment of the present invention, the first end 111 is provided with an opening 116. The opening 116 has two opposing sides along the circumference of the first end 111. The elastic portion 115 is provided on one side of the opening 116, and the other side is connected to the through-sprue 113.
