Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a wall-mounted air conditioner indoor unit and its base device. Background Technology

[0002] Wall-mounted air conditioners, as a mainstream type of household air conditioning product, are widely used in various residential and office environments. Their structure typically includes an indoor unit casing, heat exchanger, fan assembly, and base. During operation, especially in cooling or dehumidifying mode, the heat exchanger surface temperature is low, causing water vapor in the air to condense on the heat exchanger surface. This condensate drips through the drainage structure into a drip tray in the base and is eventually discharged through a drain pipe. However, due to the significant temperature difference between the indoor environment and the condensate, condensate can appear on the outer surface of the horizontal end of the base of the wall-mounted air conditioner's indoor unit. This condensate seeps from the indoor unit casing and drips into the room, reducing the user experience.

[0003] Currently, in order to prevent condensation from forming on the outer surface of the lateral ends of the base, some air conditioner manufacturers wrap insulation pads around these ends. However, this increases the production cost of the air conditioner and reduces its assembly efficiency. Utility Model Content

A flow guiding side is set at the position corresponding to the drain outlet. The flow guiding side is inclined to the anti-condensation end in the direction from front to back to guide the condensate in the water receiving trough to flow to the drain outlet.

[0014] Furthermore, the base is provided with a vortex cavity for accommodating the indoor fan of the wall-mounted air conditioner's indoor unit; and,

[0015] The water receiving trough includes a rear trough and a front trough that are interconnected. The rear trough is located behind the volute cavity, and the front trough is located in front of the volute cavity. The horizontal height of the rear trough is higher than that of the front trough. The drain outlet is located on the rear side wall of the front trough.

[0016] A baffle plate and a baffle boss are installed in the front tank. The rear part of the baffle plate is connected to the rear side wall of the rear tank, and the front part of the baffle plate is connected to the rear part of the baffle boss. The front part of the baffle boss is connected to the front side wall of the front tank.

[0017] The anti-condensation end is located at one end of the front tank in the transverse direction.

[0018] Furthermore, a fan housing assembly is provided on the base. This assembly is used to install the indoor fan of the wall-mounted air conditioner's indoor unit. The fan housing assembly is located adjacent to the anti-condensation end and is positioned behind the anti-condensation end.

[0019] The anti-condensation end includes a water-receiving side plate and a connector attached to the front of the water-receiving side plate. The connector is used to connect to the fan housing assembly, and a water-storing gap is provided between the connector and the rear side wall of the front tank. The water-storing gap is located on the side of the water-receiving side plate facing the water-receiving tank. A baffle plate is disposed within the water-storing gap, and the rear part of the baffle plate is connected to the rear side wall of the front tank, while the front part of the baffle plate is connected to the connector.

[0027] The base device of this utility model for a wall-mounted air conditioner indoor unit has a water-blocking part installed in the water receiving groove of the base. This water-blocking part is located inside the water receiving groove at the anti-condensation end, thus preventing condensate from contacting the anti-condensation end and avoiding temperature differences between the inside and outside of the water receiving groove at the anti-condensation end of the base. Therefore, the base device of this utility model can limit condensation on the outer surface of the horizontal end of the base. Furthermore, since there is no need to attach an insulation pad to the base, the production and assembly efficiency of the air conditioner indoor unit can be improved, and the production cost of the wall-mounted air conditioner indoor unit can be reduced.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0042] The following is combined with Figure 1 and Figure 2 This embodiment describes the wall-mounted air conditioner indoor unit.

[0043] Reference Figure 1 and Figure 2 In this embodiment, the wall-mounted air conditioner indoor unit may include the base device described in the following embodiments. Therefore, the wall-mounted air conditioner indoor unit of this embodiment also possesses the beneficial technical effects of the base device described in the following embodiments.

[0044] Specifically, the indoor unit of the wall-mounted air conditioner also includes a housing 100, and a base device is installed inside the housing 100.

[0045] The following is combined with Figures 2 to 5 The base device of the wall-mounted air conditioner indoor unit of this embodiment will be described in detail below. Figure 4 and Figure 5 The structure shown is part of the base 200.

[0046] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the base device of the wall-mounted air conditioner indoor unit may include a base 200 and a water-blocking part 300.

[0047] The base 200 is arranged in a transverse direction and includes a water receiving tray 210 extending in a transverse direction. The water receiving tray 210 has an upward-opening water receiving groove 211 and an anti-condensation end 212 located in its transverse direction.

[0048] The water-blocking part 300 is disposed in the water receiving tank 211 and is disposed adjacent to the anti-condensation end 212. The water-blocking part 300 is disposed on the inside of the anti-condensation end 212 located in the water receiving tank 211. The water-blocking part 300 is used to restrict the condensate in the water receiving tank 211 from contacting the anti-condensation end 212.

[0049] Since the base 200 of the wall-mounted air conditioner indoor unit base device in this embodiment is provided with a water-blocking part 300 in the water receiving groove 211, and the water-blocking part 300 is located on the inner side of the anti-condensation end 212 located in the water receiving groove 211, it can limit the condensate in the water receiving groove 211 from contacting the anti-condensation end 212, so as to avoid the temperature difference between the inside and outside of the water receiving groove 211 on the anti-condensation end 212 of the base 200 in the lateral direction.

[0050] Therefore, the base device of the wall-mounted air conditioner indoor unit in this embodiment can limit the appearance of condensation on the outer surface of the lateral end of the base 200. At the same time, since there is no need to attach an insulation pad to the base 200, the production and assembly efficiency of the air conditioner indoor unit can be improved, and the production cost of the wall-mounted air conditioner indoor unit can be reduced.

[0051] Reference Figure 3 and Figure 4 In this embodiment, the bottom of the water-blocking part 300 is connected to the bottom of the water-receiving trough 211, the top of the water-blocking part 300 extends upward, the front part of the water-blocking part 300 is connected to the front side wall of the water-receiving trough 211, and the rear part of the water-blocking part 300 is connected to the rear side wall of the water-receiving trough 211.

[0052] It is understandable that by connecting the bottom of the water-blocking part 300 to the bottom of the water-receiving trough 211, extending the top of the water-blocking part 300 upward, connecting the front part of the water-blocking part 300 to the front side wall of the water-receiving trough 211, and connecting the rear part of the water-blocking part 300 to the rear side wall of the water-receiving trough 211, the water-blocking part 300 can be positioned on the inner side of the anti-condensation end 212 of the water-receiving trough 211. This not only limits the appearance of condensate on the outer surface of the lateral end of the base 200, but also improves the production and assembly efficiency of the indoor air conditioning unit and reduces the production cost of the wall-mounted indoor air conditioning unit.

[0053] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, a drain outlet 213 is provided on the rear side wall of the water receiving tank 211, and the drain outlet 213 is provided adjacent to the anti-condensation end 212.

[0054] Understandably, a drain pipe connector 2131 is provided on the outer surface of the base 200 at the position corresponding to the drain outlet 213, and a drain pipe extending to the outdoor space can be installed on the drain pipe connector 2131. The condensate in the water collection tank 211 can be discharged to the outside through the drain outlet 213, the drain pipe connector 2131 and the drain pipe in sequence.

[0055] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the water-blocking part 300 may include a water-blocking plate 310 and a water-blocking boss 320.

[0056] A baffle plate 310 is installed inside a water receiving trough 211. The baffle plate 310 is installed adjacent to the anti-condensation end 212, and one side of the baffle plate 310 faces the anti-condensation end 212. The rear part of the baffle plate 310 is connected to the rear side wall of the water receiving trough 211, the bottom of the baffle plate 310 is connected to the bottom of the water receiving trough 211, the top of the baffle plate 310 extends upward, and the drain outlet 213 is located on the side of the baffle plate 310 facing away from the anti-condensation end 212.

[0057] The water-blocking protrusion 320 is located inside the water receiving tank 211. The water-blocking protrusion 320 is set at the bottom of the water receiving tank 211, and the top of the water-blocking protrusion 320 extends upward. The water-blocking protrusion 320 is located in front of the drain outlet 213 and the baffle plate 310, and the rear part of the water-blocking protrusion 320 is connected to the front part of the baffle plate 310. The water-blocking protrusion 320 is provided with a flow guiding side 321 at the position corresponding to the drain outlet 213. The flow guiding side 321 is inclined to the anti-condensation end 212 in the direction from front to back to guide the condensate in the water receiving tank 211 to flow to the drain outlet 213.

[0058] Understandably, the baffle plate 310 can restrict the condensate in the water receiving tank 211 from contacting the anti-condensation end 212, and the baffle boss 320 can guide the condensate in the water receiving tank 211 to flow towards the drain outlet 213 instead of towards the anti-condensation end 212. Therefore, the configuration of the baffle plate 310 and the baffle boss 320 can enable the baffle part 300 to restrict the condensate in the water receiving tank 211 from contacting the anti-condensation end 212, thereby improving the production and assembly efficiency of the indoor air conditioner unit and reducing the production cost of the wall-mounted indoor air conditioner unit while restricting the appearance of condensate on the lateral end outer surface of the base 200.

[0059] Additionally, it should be noted that the condensate in the water collection tank 211 can be configured to be discharged to the outdoor space in real time through the drain outlet 213, so that the liquid level of the condensate in the water collection tank 211 will not be too high. Therefore, the height of the water-blocking protrusion 320 can be set to be lower than the height of the water-blocking plate 310, and the water-blocking protrusion 320 can guide the condensate to the drain outlet 213.

[0060] However, since the horizontal height of the drain outlet 213 is lower than other parts of the bottom of the water receiving tank 211, condensate with a high liquid level may remain in the water storage gap 230 in the following embodiments. Therefore, the height of the baffle plate 310 can be set higher.

[0061] Reference Figure 2 In this embodiment, the base 200 is provided with a vortex 220 for accommodating the indoor fan (not shown) of the wall-mounted air conditioner indoor unit.

[0062] It should be noted that an indoor fan (not shown) is connected to the indoor fan. Driven by the indoor fan, the rotation of the indoor fan (not shown) can cause the indoor airflow to enter the air conditioner indoor unit casing 100, and cause the airflow to flow through the water receiving pan 210 and the indoor heat exchanger (not shown) arranged above the volute 220. Then, the heat-exchanged airflow is caused to flow through the volute 220 on the base 200 and the air outlet duct 270 into the indoor space, so as to regulate the ambient temperature of the indoor space.

[0063] Reference Figure 2 In this embodiment, the water receiving tank 211 includes a rear tank 214 and a front tank 215 that are connected to each other. The rear tank 214 is located behind the volute 220, and the front tank 215 is located in front of the volute 220. The horizontal height of the rear tank 214 is higher than that of the front tank 215. The drain outlet 213 is provided on the rear side wall of the front tank 215.

[0064] Understandably, the cross-section of the indoor heat exchanger can be an inverted "V" shape. Correspondingly, in order for the drip tray 210 to fully collect the condensate sliding down the indoor heat exchanger, the drip tray 211 can be configured as two interconnected tanks (rear tank 214 and front tank 215). Furthermore, in order for the condensate in the two tanks to flow out to the outside through the drain outlet 213, the horizontal height of the front tank 215, which is equipped with the drain outlet 213, can be lower than that of the rear tank 214.

[0065] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the baffle plate 310 and the baffle boss 320 are disposed in the front groove 215. The rear part of the baffle plate 310 is connected to the rear side wall of the rear groove 214, the front part of the baffle plate 310 is connected to the rear part of the baffle boss 320, and the front part of the baffle boss 320 is connected to the front side wall of the front groove 215.

[0066] Furthermore, the anti-condensation end 212 is located at one end of the front tank 215 in the transverse direction.

[0067] It is understood that the water-blocking part 300 can be provided in the front tank 215, and the anti-condensation end 212 can be one end located in the lateral direction of the front tank 215, so as to limit the condensate in the front tank 215 from contacting the anti-condensation end 212 and limit the generation of condensate on the outer surface of one end of the front water receiving tank 211.

[0068] Reference Figure 2 and Figure 3 In this embodiment, a fan housing assembly 400 is provided on the base 200. The fan housing assembly 400 is used to install the indoor fan of the wall-mounted air conditioner indoor unit. The fan housing assembly 400 is provided adjacent to the anti-condensation end 212 and is located behind the anti-condensation end 212.

[0069] Understandably, the indoor fan can be mounted on the base 200 via the fan housing assembly 400, thereby driving the indoor fan connected to the indoor fan and causing the indoor fan to rotate.

[0070] In this embodiment, the fan housing assembly 400 may include a bottom cover 410, a top cover (not shown), and a top cover (not shown).

[0071] The top cover is installed above the bottom cover 410, the indoor fan is fixed between the bottom cover 410 and the top cover, and the cover is installed on the top cover.

[0072] It is important to understand that, because the anti-condensation end 212 is close to the indoor fan, a large amount of heat is generated during the operation of the indoor fan. Under the influence of this heat, a temperature difference will further develop between the inner and outer sides of the water collection tank 211 at the anti-condensation end 212, and condensate will further precipitate on the outer surface of the anti-condensation end 212. Therefore, by providing the aforementioned water-blocking part 300, the base device of this embodiment can limit the contact of condensate with the anti-condensation end 212, thereby limiting the temperature difference between the inner and outer sides of the anti-condensation end 212. Even if the indoor fan dissipates heat to the anti-condensation end 212, condensate can still be limited from appearing on the outer surface of the lateral end (anti-condensation end 212) of the base 200, improving the production and assembly efficiency of the wall-mounted air conditioner indoor unit and reducing its production cost.

[0073] It should also be understood that the electrical control components (e.g., main circuit board, not shown) of the indoor unit are typically located in the anti-condensation end 212 and the outer periphery of the indoor fan. These electrical control components also generate heat. Therefore, for the same reasons mentioned above, the base device of this embodiment can also limit the appearance of condensation on the outer surface of the lateral end (anti-condensation end 212) of the base 200, improve the production and assembly efficiency of the wall-mounted indoor unit, and reduce the production cost of the wall-mounted indoor unit.

[0074] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the anti-condensation end 212 includes a water receiving side plate 2121 and a connector 2122 connected to the front of the water receiving side plate 2121. The connector 2122 is used to connect the fan housing assembly 400. A water storage gap 230 is provided between the connector 2122 and the rear side wall of the front tank 215. The water storage gap 230 is located on the side of the water receiving side plate 2121 facing the water receiving tank 211. A baffle plate 310 is disposed in the water storage gap 230, and the rear part of the baffle plate 310 is connected to the rear side wall of the front tank 215, while the front part of the baffle plate 310 is connected to the connector 2122.

[0075] Furthermore, the water-blocking boss 320 is connected to the side of the connector 2122 facing the water inlet 211, and the rear of the water-blocking boss 320 extends to the front of the water-blocking plate 310.

[0076] Understandably, the fan housing assembly 400 can be connected to the base 200 via the connector 2122. Specifically, the cover can be connected to the connector 2122 (connecting screw post 2123).

[0077] Reference Figure 3 and Figure 4 In this embodiment, a reinforcing rib 240 is provided between the top surface of the water-blocking boss 320 and the side of the connector 2122 facing the water receiving tank 211 to ensure the connection stability between the connector 2122 and the base 200.

[0078] Reference Figure 3 and Figure 4 In this embodiment, the number of reinforcing ribs 240 can be set to multiple, and the multiple reinforcing ribs 240 can be spaced apart along the front-back direction to further ensure the connection stability between the connector 2122 and the base 200.

[0079] Reference Figure 4 In this embodiment, a water storage tank 250 is provided between the connector 2122, the water receiving side plate 2121, and the water baffle 310. Furthermore,

[0080] The top of the water baffle 310 has a connecting notch 311.

[0081] It should be understood that the configuration of the baffle plate 310 will create a water storage tank 250 at the water storage gap 230. In some cases (a small probability), condensate may fall into the water storage tank 250, and after a certain period of time, the condensate will lose its coldness and turn into room temperature water. In this case, the room temperature water in the water storage tank 250 will further isolate the condensate in the water receiving tank 211 from the anti-condensation end 212 (water receiving side plate 2121) to exchange heat, so as to further prevent condensate from appearing on the outer surface of the transverse end (anti-condensation end 212 or water receiving side plate 2121) of the base 200.

[0082] Furthermore, by setting the connecting gap 311, the water in the water storage tank 250 is guided to flow into the receiving tank 211 and then to the outside through the drain outlet 213, thus preventing the water in the water storage tank 250 from overflowing and falling onto the indoor floor, ensuring the user's experience.

[0083] Reference Figure 3 and Figure 4 In this embodiment, the water-blocking boss 320 has a water-blocking side 323 facing away from the anti-condensation end 212 and a water-storing side 322 facing the drain outlet 213, and the flow-guiding side 321 is located between the water-blocking side 323 and the water-storing side 322.

[0084] Understandably, the water-blocking side 323 can restrict the flow of condensate in the water receiving tank 211 to the anti-condensation end 212 and promote its flow to the flow-guiding side 321; the water-storing side 322 can restrict the flow of condensate between the water-storing side 322 and the rear side wall of the front tank 215 to the anti-condensation end 212 (connector 2122), and thus the water-blocking boss 320 can restrict the condensate from contacting the anti-condensation end 212 (connector 2122).

[0085] Reference Figure 5 In this embodiment, a water-blocking recess 260 is provided on the outer bottom surface of the water receiving tray 210 at the position corresponding to the water-blocking protrusion 320.

[0086] It is understandable that the water-blocking protrusion 320 can be formed by recessing the water-blocking protrusion 320 into the outer bottom surface of the water receiving tray 210 at the position corresponding to the water-blocking protrusion 320, in order to reduce the production and manufacturing costs of the water-blocking part 300, the water receiving tray 210 and the base 200.

[0087] In some other embodiments, the difference from the above embodiments is that the water-blocking part 300 may include a water-blocking plate 310 extending in the front-rear direction.

[0088] Specifically, the front end of the baffle plate 310 is connected to the front side wall of the water receiving trough 211, and the rear end of the baffle plate 310 is connected to the rear side wall of the water receiving trough 211. Similarly, it can restrict the water in the water receiving trough 211 from contacting the anti-condensation end 212 and suppress the appearance of condensation on the outer surface of the lateral end of the base 200.

[0089] In some other embodiments, the difference from the above embodiments is that the water-blocking part 300 may include a water-blocking platform extending in the front-rear direction.

[0090] Specifically, the front end of the water baffle is connected to the front side wall of the water receiving trough 211, and the rear end of the water baffle is connected to the rear side wall of the water receiving trough 211. Similarly, it can restrict the water in the water receiving trough 211 from contacting the anti-condensation end 212 and suppress the appearance of condensation on the outer surface of the lateral end of the base 200.
