Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to a wall-mounted air conditioner indoor unit and an air conditioner. Background Technology

[0002] In wall-mounted air conditioner indoor units, a motor cover is often used to secure the cross-flow fan motor. After the motor cover is fixed to the base with screws, the motor cover and base are in a mating state. During the cooling operation of the wall-mounted air conditioner indoor unit, due to the low temperature of the refrigerant pipes, condensation occurs on the wall of the refrigerant pipe receiving cavity in the base due to the exchange of hot and cold air. Since the motor cover and base are located below the refrigerant pipe receiving cavity wall, the mating surface between the motor cover and base prevents condensation from entering the air duct. Furthermore, the motor cover usually has a water-blocking rib; when condensation from the evaporator flows to the motor cover, it flows along the water-blocking rib into the drip tray and is eventually discharged through the drain pipe.

[0003] However, since the motor cover is made of plastic, gaps will form between the motor cover and the base under long-term use or the vibration of the cross-flow fan motor. This allows condensation to flow into the air duct through these gaps. Under the influence of airflow and the centrifugal force of the cross-flow fan, some of the condensation is blown out of the air duct, affecting the user experience, while the rest collects along the air duct to the air outlet and drips, causing leakage. Utility Model Content

[0004] The first objective of this utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem of water leakage caused by the gap between the motor cover and the base of existing wall-mounted air conditioner indoor units, which makes it easy for condensate produced by the evaporator to enter the air duct.

[0005] The wall-mounted air conditioner indoor unit provided by this utility model includes a base and a motor cover. The base is provided with a refrigerant pipe receiving cavity wall, a water inlet groove and a pressing surface from top to bottom. The motor cover is in contact with the pressing surface and the pressing surface is higher than the water inlet groove. The water inlet groove is connected to the drain outlet of the wall-mounted air conditioner indoor unit.

[0006] When the indoor unit of this wall-mounted air conditioner is in cooling operation, condensation generated by the exchange of hot and cold air will form on the wall of the refrigerant pipe housing and flow downwards along the wall. By setting a water guide groove between the wall of the refrigerant pipe housing and the pressing surface of the base for mating with the motor cover, the condensation flowing downwards along the wall of the refrigerant pipe housing will flow into the water guide groove, which is lower than the pressing surface, and then flow further along the water guide groove to the drain outlet of the wall-mounted air conditioner indoor unit, and finally flow out from the drain outlet.

[0007] Therefore, it can be seen that the indoor unit of this wall-mounted air conditioner uses a water channel between the refrigerant pipe housing wall and the motor cover to drain the condensate generated on the refrigerant pipe housing wall, preventing water leakage caused by this condensate entering the air duct through the gap between the motor cover and the base.

[0008] Furthermore, the base is provided with a water channel extending in the left-right direction. One end of the water channel is connected to the water inlet trough, and the other end is connected to the drain outlet. This design of providing a water channel in the base eliminates the need for additional components to form the water channel, saving on the number of parts and ensuring a compact structure for the wall-mounted air conditioner indoor unit. On the other hand, the flow of condensed water in the water channel also helps to remove heat transferred to the base during the operation of the cross-flow fan motor, preventing heat concentration in the base.

[0009] Furthermore, the water inlet trough is provided with an inclined water inlet section, which extends downwards from the water inlet trough towards the water channel. This inclined water inlet section allows condensate entering the water inlet trough to flow smoothly into the water channel under its own weight, reducing the accumulation of condensate in the water inlet trough and preventing condensate from accumulating in the water inlet trough and flowing back into the air channel through the mating part between the motor cover and the base.

[0010] Furthermore, the water inlet trough includes a top wall for connecting to the refrigerant pipe receiving cavity wall, a bottom wall for connecting to the pressing surface, and a connecting wall located between the top wall and the bottom wall. The top wall, the connecting wall, and the bottom wall are arranged in a U-shape, wherein the bottom wall is provided with the inclined water inlet portion. This arrangement allows a groove with a certain capacity to be formed between the refrigerant pipe receiving cavity wall and the pressing surface, thereby meeting the temporary storage needs of a small amount of condensate and preventing leakage from the mating part between the motor cover and the base due to condensate accumulation.

[0011] Furthermore, the water intake channel includes a water intake section and a confluence section arranged sequentially. The confluence section is located between the water intake section and the waterway, and the flow area of ​​the confluence section is larger than that of the water intake section. By setting a confluence section with a larger flow area at the end of the water intake channel, that is, by connecting the water intake channel to the waterway through the confluence section, the condensate in the water intake channel can be temporarily stored and its flow velocity reduced before entering the waterway, thus preventing the condensate from flowing too fast and failing to accurately enter the waterway.

[0012] Furthermore, the connecting wall extends obliquely upwards towards the rear of the base at the junction section. This arrangement allows condensate to be guided away from the pressing surface by the connecting wall when it enters the junction section, i.e., guiding the condensate away from the contact area between the motor cover and the base, thus preventing the condensate from flowing back into the air duct through the aforementioned area.

[0013] Furthermore, the waterway includes a front waterway and a rear waterway. The front waterway is formed on the front surface of the base, and the rear waterway is formed on the rear surface of the base. The base also has a flow-through hole, through which the front waterway and the rear waterway communicate. The front waterway is connected to the water inlet channel, and the rear waterway is connected to the drain outlet. This arrangement of the waterway reduces the accumulation of condensate on the front surface of the base, thereby reducing interference with the cross-flow fan motor located at the front of the base.

[0014] Furthermore, the rear water channel is inclined downwards. This design allows condensate entering the rear water channel to flow smoothly to the drain outlet under its own weight, thereby reducing the accumulation of condensate in the rear water channel.

[0015] Furthermore, the pressing surface has at least one connecting hole for fixing the motor cover to the base. This design ensures reliable assembly of the motor cover and the base, preventing the motor cover from detaching from the base.

[0016] The second objective of this utility model is to provide an air conditioner that solves the technical problem of water leakage caused by the gap between the motor cover and the base of the existing wall-mounted air conditioner indoor unit, which makes it easy for the condensate produced by the evaporator to enter the air duct.

[0017] The air conditioner provided by this utility model includes an outdoor unit and the aforementioned wall-mounted indoor unit, wherein the wall-mounted indoor unit is connected to the outdoor unit via a refrigerant pipeline.

[0018] By installing the aforementioned wall-mounted air conditioner indoor unit in the air conditioner, the air conditioner accordingly possesses all the advantages of the aforementioned wall-mounted air conditioner indoor unit, which will not be elaborated upon here. Attached Figure Description

Detailed Implementation

[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0032] This embodiment provides a wall-mounted air conditioner indoor unit, such as Figure 7 and Figure 8 As shown, it includes a base 100 and a motor cover 200. Specifically, the motor cover 200 is in contact with the pressing surface 130.

[0033] like Figures 1 to 4 As shown, the base 100 is provided with a refrigerant pipe receiving cavity wall 110, a water inlet trough 120 and a pressing surface 130 from top to bottom. The pressing surface 130 is higher than the water inlet trough 120, and the water inlet trough 120 is connected to the drain outlet 300 of the wall-mounted air conditioner indoor unit.

[0034] When the indoor unit of this wall-mounted air conditioner is in cooling operation, condensation generated by the exchange of hot and cold air will form on the wall 110 of the refrigerant pipe receiving cavity and flow downwards along the wall 110. By providing a water channel 120 between the wall 110 of the refrigerant pipe receiving cavity and the pressing surface 130 of the base 100 for cooperating with the motor cover 200, the condensation flowing downwards along the wall 110 of the refrigerant pipe receiving cavity will flow into the water channel 120, which is lower than the pressing surface 130, and then flow further along the water channel 120 to the drain outlet 300 of the wall-mounted air conditioner indoor unit, and finally flow out from the drain outlet 300.

[0035] As can be seen, the wall-mounted air conditioner indoor unit utilizes the water channel 120 between the refrigerant pipe receiving cavity wall 110 and the motor cover 200 to drain the condensate generated in the refrigerant pipe receiving cavity wall 110, preventing water leakage caused by this condensate entering the air duct through the gap between the motor cover 200 and the base 100.

[0036] It should be noted that, generally speaking, one side of the wall-mounted air conditioner indoor unit is the side facing the room or the user's activity area; this side is the front of the indoor unit. The side facing a corner or the wall itself is the rear side. When a user is facing the indoor unit, the user's left side is the left side of the indoor unit, and the user's right side is the right side. Specifically, in this embodiment, the vertical, front-back, and horizontal directions of the wall-mounted air conditioner indoor unit are as follows: Figure 1 The corresponding arrows are shown in the diagram.

[0037] In this embodiment, the base 100 is provided with a water channel extending in the left and right direction, wherein one end of the water channel is connected to the water inlet trough 120 and the other end of the water channel is connected to the drain outlet 300.

[0038] This design allows condensed water dripping into the water inlet 120 to flow along the water channels of the base 100 to the drain outlet 300, thus facilitating the discharge of the condensed water. This method of incorporating water channels in the base 100 eliminates the need for additional components to form these channels, saving on parts and ensuring a compact structure for the wall-mounted air conditioner indoor unit. Furthermore, the flow of condensed water in the channels helps to remove heat transferred to the base 100 during the operation of the cross-flow fan motor, preventing heat concentration in the base 100.

[0039] In this embodiment, the waterway may include a front waterway 140 and a rear waterway. Specifically, the front waterway 140 is formed on the front surface of the base 100, and the rear waterway is formed on the rear surface of the base 100. The base 100 is also provided with a flow hole 150. The front waterway 140 and the rear waterway are connected in the flow hole 150. The front waterway 140 is connected to the water inlet trough 120, and the rear waterway is connected to the drain outlet 300.

[0040] When the indoor unit of the wall-mounted air conditioner is in cooling mode, the condensate formed on the refrigerant pipe cavity wall 110 flows downward through the multi-layer slope of the cavity wall and enters the water inlet 120. Then, the condensate flows out through the water inlet 120 to the front water channel 140, and further flows through the flow hole 150 to the rear water channel. Finally, it flows through the rear water channel to the drain outlet 300 to be discharged to the outside of the indoor unit of the wall-mounted air conditioner.

[0041] This waterway configuration reduces the accumulation of condensate on the front surface of the base 100, thereby minimizing interference with the cross-flow fan motor located at the front of the base 100.

[0042] In this embodiment, the length of the rear water channel is greater than the length of the front water channel 140. That is, the front water channel 140 is shorter and the rear water channel is longer. This arrangement allows the condensate flowing from the water inlet trough 120 to the front water channel 140 to flow to the rear water channel as quickly as possible, thereby further reducing interference with the cross-flow fan motor at the front of the base 100.

[0043] In this embodiment, the rear waterway is inclined downwards.

[0044] This design allows condensate entering the back drain to flow smoothly to the drain outlet 300 under its own weight, thus reducing the accumulation of condensate in the back drain.

[0045] Please continue to refer to Figure 3 In this embodiment, the water inlet trough 120 is provided with an inclined water inlet 124. Specifically, the inclined water inlet 124 extends downward in an inclined manner from the water inlet trough 120 toward the waterway.

[0046] The aforementioned inclined water inlet 124 allows the condensate entering the water inlet trough 120 to flow smoothly into the waterway under its own weight, thereby reducing the accumulation of condensate in the water inlet trough 120 and preventing the condensate from flowing back into the airway through the mating part between the motor cover 200 and the base 100 due to the accumulation of condensate in the water inlet trough 120.

[0047] like Figure 5 and Figure 6 As shown, in this embodiment, the water inlet trough 120 includes a top wall 121 for connecting to the refrigerant pipe receiving cavity wall 110, a bottom wall 122 for connecting to the pressing surface 130, and a connecting wall 123 located between the top wall 121 and the bottom wall 122. The top wall 121, the connecting wall 123 and the bottom wall 122 are arranged in a U-shape, wherein the bottom wall 122 is provided with an inclined water inlet portion 124.

[0048] The above-described structure of the water inlet trough 120 allows a groove with a certain capacity to be formed between the refrigerant pipe receiving cavity wall 110 and the pressing surface 130, thereby meeting the temporary storage requirements for a small amount of condensate and preventing leakage from the mating part of the motor cover 200 and the base 100 due to condensate accumulation.

[0049] Please continue to refer to Figure 3 In this embodiment, the water intake channel 120 may include a water intake section 125 and a confluence section 126 arranged in sequence. The confluence section 126 is located between the water intake section 125 and the waterway, and the flow area of ​​the confluence section 126 is greater than the flow area of ​​the water intake section 125.

[0050] By setting a confluence section 126 with a large flow area at the end of the water intake channel 120, that is, by connecting the water intake channel 120 to the waterway through the confluence section 126, the condensate in the water intake channel 120 can be temporarily stored in the confluence section 126 and the flow rate can be reduced before entering the waterway, so as to avoid the condensate from flowing too fast and failing to enter the waterway accurately.

[0051] Please continue to refer to Figure 3 In this embodiment, the connecting wall 123 extends obliquely upward toward the rear of the base 100 at the junction section 126.

[0052] This design allows the condensate to be guided away from the pressing surface 130 by the connecting wall 123 when it enters the confluence section 126. In other words, it guides the condensate away from the contact area between the motor cover 200 and the base 100, preventing the condensate from flowing back into the air duct through the aforementioned area.

[0053] Please continue to refer to Figure 3 In this embodiment, the pressing surface 130 is provided with at least one connecting hole 131, which is used to fix the motor cover 200 and the base 100. This method of connecting the motor cover 200 and the base 100 together using the connecting hole 131 can ensure the reliable assembly of the motor cover 200 and the base 100 and prevent the motor cover 200 from falling off the base 100.

[0054] Specifically, in this embodiment, the connecting hole 131 can be a threaded hole. Correspondingly, a light hole can be opened in the motor cover 200. By passing the connecting screw through the light hole of the motor cover 200 and screwing it into the connecting hole 131 opened in the pressing surface 130, the assembly connection between the motor cover 200 and the base 100 can be realized.

[0055] In this embodiment, the pressing surface 130 has two connecting holes 131.

[0056] In addition, this embodiment also provides an air conditioner, including an outdoor unit and the aforementioned wall-mounted indoor unit, wherein the wall-mounted indoor unit is connected to the outdoor unit via a refrigerant pipeline.

[0057] By installing the aforementioned wall-mounted air conditioner indoor unit in the air conditioner, the air conditioner accordingly possesses all the advantages of the aforementioned wall-mounted air conditioner indoor unit, which will not be elaborated upon here.
