Description

Technical Field

[0001] The present application relates to the field of heat exchange technology, and in particular to a water pumping structure, an air conditioner, and an air conditioning range hood system. Background Art

[0002] With the development of society and the improvement of people's living standards, air conditioners are widely used in people's production and life, effectively improving the comfort of people's production and living environment.

[0003] When an air conditioner performs heat exchange, the outside air exchanges heat with the heat exchanger, cooling it and producing condensed water. This condensed water drips from the heat exchanger surface and settles in a water collection trough on the air conditioner base, preventing it from contaminating other air conditioner components or the floor. To fully utilize the condensed water to cool the heat exchanger fins, some air conditioners have a pumping mechanism at the bottom of the heat exchanger fins. This pumping mechanism includes a pumping motor that disperses the condensed water deposited on the air conditioner base and sprays it onto the heat exchanger fins, allowing the refrigerant in the fins to exchange heat with the condensed water. This improves the heat exchange efficiency of the heat exchanger and speeds up the heat exchange process. As the refrigerant flows through the heat exchanger, it releases heat into the condensed water, thereby lowering the refrigerant's temperature.

[0004] However, as the condensed water is scattered and splashed by the impeller of the water pumping motor, the condensed water may splash outside the heat exchange fins, thereby affecting the normal operation of other circuits or components of the air conditioner and affecting the service life of the air conditioner.

[0035] See Figure 1 and Figure 2 , Figure 1 FIG2 shows a partial structural diagram of an air conditioner in an embodiment of the present application. Figure 2 A schematic diagram of the assembly of an air conditioner base and a water pumping assembly according to an embodiment of the present application is shown.

[0036] An embodiment of the present application provides an air-conditioning hood system, comprising an air conditioner and a range hood. The main function of the range hood is to absorb the fumes generated during cooking, while the air conditioner is used to cool the kitchen. The air conditioner comprises an air conditioner base 100 and a heat exchanger mounted on the air conditioner base 100. The air conditioner base 100 is a shell-like structure, and one side surface of the air conditioner base 100 is recessed inward to form a water receiving tank 100a. In the following embodiments, the cross-section of the water receiving tank 100a is roughly rectangular, and the width direction of the water receiving tank 100a is defined as the first direction (i.e. Figure 1 The length direction of the water receiving tank 100a is the second direction (i.e. Figure 1 The depth direction of the water receiving tank 100a is the third direction (i.e. Figure 1 It is understood that the shape of the water receiving tank 100a is not limited thereto and can be configured as needed to meet the requirements for collecting condensed water.

[0037] The heat exchange fins 210 of the heat exchanger are located above the water receiving tank 100a (i.e., on one side of the third direction of the water receiving tank 100a). The condensed water precipitated by the heat exchange and cooling of the outside air by the heat exchanger drips from the surface of the heat exchange fins 210 into the water receiving tank 100a under the action of gravity. The water receiving tank 100a is used to collect and store the condensed water to prevent the condensed water from contaminating other components of the air conditioner or the ground.

[0038] Specifically in some embodiments, the heat exchanger includes a fin bracket 230 and two heat exchange fins 210 installed on the fin bracket 230, and the two heat exchange fins 210 are parallel and spaced apart along a first direction, the thickness direction of each heat exchange fin 210 extends along the first direction, the length direction of the heat exchange fin 210 extends along the second direction, and the height direction of the heat exchange fin 210 extends along the third direction.

[0039] Please continue reading Figure 1 and Figure 2To utilize condensed water to cool the heat exchange fins 210 of the heat exchanger, the air conditioner base 100 further includes a water pumping structure 300. The water pumping structure 300 includes a water pumping assembly 320, which is located on one side of the air conditioner base 100 in the second direction. The water pumping assembly 320 includes a driving member 321 and a water pumping wheel 323. The driving member 321 includes a driving member body 3212 and an output shaft 3214. The driving member body 3212 is mounted on the air conditioner base 100 and is located outside the water receiving tank 100a in the second direction. One end of the output shaft 3214 is connected to the driving member body 3212, and the other end of the output shaft 3214 extends along the first direction between the water receiving tank 100a and the heat exchange fins 210. The water wheel 323 has a disc-shaped structure. The water wheel 323 is fixed to the end of the output shaft 3214 away from the driving member 321 to be in transmission connection with the driving member 321. The central axis of the water wheel 323 extends along the first direction. The water wheel 323 is located between the two heat exchange fins 210 in the first direction and is at least partially located in the water receiving trough 100a. The water wheel 323 can rotate with the central axis of the output shaft 3214 as the rotating axis under the drive of the driving member 321.

[0040] In this way, the water pump 323 can throw the condensed water deposited in the water receiving tank 100a back onto the two adjacent heat exchange fins 210. The condensed water can then exchange heat with the refrigerant flowing within the heat exchange fins 210, reducing the refrigerant's temperature. This allows the condensed water to be reused and improves the heat exchange efficiency of the air conditioner. However, as described in the background art, as the condensed water is rotated and thrown by the water pump assembly 320, it may splash outside the heat exchange fins 210, thereby affecting the normal operation of other circuits and components of the air conditioner.

[0041] In order to solve the above problems, combined Figure 3 and Figure 4 As shown, Figure 3 A schematic diagram of a water pumping structure in an embodiment of the present application is shown. Figure 4 An exploded schematic diagram of a water pumping structure in one embodiment of the present application is shown. In some embodiments, the water pumping structure 300 of the present application further includes a water retaining assembly 340, which is located on a side of the water pumping wheel 323 axially adjacent to the driving member 321 and / or on a side of the water pumping wheel 323 in a radial direction.

[0042] In this way, the water-blocking component 340 can block the condensed water scattered by the water-pumping component 320, limit the flight path of the condensed water scattered by the water-pumping component 320 to the heat exchanger, effectively prevent the condensed water from splashing outward, and avoid affecting the normal operation of other circuits or components of the air conditioner.

[0043] like Figure 1 、 Figure 3 as well as Figure 4As shown, in some embodiments, the water retaining assembly 340 includes an axial water retaining unit 341, which is located on the side of the water wheel 323 axially (i.e., in the first direction) close to the driving member 321. When the water retaining structure 300 is installed on the air conditioner base 100, the axial water retaining unit 341 is at least partially located on the side of the heat exchange fin 210 in the first direction. In this way, condensed water splashed by the water wheel 323 can be prevented from splashing along the first direction toward the driving member 321.

[0044] It can be understood that in some embodiments, the shape of the axial water retaining unit 341 is not limited and can be set according to the shape of the gap between the heat exchange fins 200 and the air conditioner base 100 and the water pumping assembly 320, thereby playing a good blocking role for the condensed water scattered by the water pumping assembly 320.

[0045] In other embodiments, the axial water retaining unit 341 includes a first axial water retaining member 3412 and a second axial water retaining member 3414. The second axial water retaining member 3414 is connected to the air conditioner base 100 and is mainly used to prevent the condensed water in the water receiving trough 100a from overflowing. The first axial water retaining member 3412 is supported on the side of the second axial water retaining member 3414 facing away from the air conditioner base 100 and is mainly used to prevent the condensed water scattered by the water pumping component 320 from splashing outward.

[0046] Specifically, the second axial water retaining member 3414 is an elongated strip extending along the second direction and extending from one end of the water receiving trough 100a to the other end of the water receiving trough 100a along the second direction. The second axial water retaining member 3414 includes a first water retaining portion 3413 and a second water retaining portion 3415 that are interconnected. The first water retaining portion 3413 extends into the water receiving trough 100a and abuts against a side wall of the water receiving trough 100a that is close to the driving member 321 in the first direction. One side of the second water retaining portion 3415 is connected to the first water retaining portion 3413, and the other side of the second water retaining portion 3415 extends toward the driving member 321. The second water retaining portion 3415 is located outside the water receiving trough 100a and abuts against the air conditioner base 100.

[0047] In this way, the second axial water barrier 3414 is attached to the edge of one side of the water receiving trough 100a close to the driving member 321 in the first direction, thereby increasing the depth of the side of the water receiving trough 100a close to the driving member 321 in the first direction to a certain extent, and then increasing the storage capacity of the water receiving trough 100a, which prevents excessive condensation water from overflowing from the water receiving trough 100a.

[0048] As a preferred embodiment, the second water retaining portion 3415 is provided with a plurality of overflow troughs 3415a. These overflow troughs 3415a are arranged sequentially along the second direction from one end of the water receiving trough 100a to the other, and each overflow trough 3415a is connected to the water receiving trough 100a. This allows for overflowing water in the water receiving trough 100a, preventing it from spilling into other areas of the air conditioner base 100 or onto the ground. It is understood that the shape and number of overflow troughs 3415a are not limited to this and can be configured to meet different requirements.

[0049] In some embodiments, the second water retaining portion 3415 further defines two mounting holes, which are spaced apart along the second direction and are respectively located at the bottom of an overflow groove 3415a. Fasteners such as screws can pass through the mounting holes along the third direction to connect to the air conditioner base 100, thereby removably fixing the first axial water retaining member 3412 to the air conditioner base 100. It will be understood that the number and location of the mounting holes defined in the second water retaining portion 3415 are not limited and can be provided as needed to meet different installation requirements.

[0050] The first axial water stopper 3412 is a generally rectangular plate-shaped structure. It is supported on the first water stopper portion 3413 and the second water stopper portion 3415 of the second axial water stopper 3414 and is located at an end of the second axial water stopper 3414 that is closer to the water pumping assembly 320 in the second direction. The thickness of the first axial water stopper 3412 extends along the first direction, the width of the first axial water stopper 3412 extends along the third direction, and the length of the first axial water stopper 3412 extends along the second direction. The length of the first axial water stopper 3412 is shorter than the length of the second axial water stopper 3414 in the second direction. When installed on the air conditioner base 100, the first axial water stopper 3412 is located below the side of the heat dissipating fins 210 that is closer to the driving member 321 in the first direction, thereby preventing condensed water scattered by the water pumping assembly 320 from splashing outward in the first direction. It is understood that the shape of the first axial water retaining member 3412 is not limited and can be configured according to the shapes of the air conditioner base 100 and the heat exchange fins 210 to effectively block the condensed water dispersed and scattered by the water pumping assembly 320. In other embodiments, the first axial water retaining member 3412 can also be supported only on one of the first water retaining portion 3413 or the second water retaining portion 3415.

[0051] As a preferred embodiment, the shape of the end wall of the first axial water retaining member 3412 that contacts the second water retaining portion 3415 matches the shape of the second water retaining portion 3415, thereby tightly fitting with the second water retaining portion 3415 to close the gap between the heat exchange fins 210 and the air conditioner base 100. Furthermore, the first axial water retaining member 3412 has an avoidance groove at one end in the second direction to facilitate the passage of the output shaft 3214 of the driving member 321.

[0052] Furthermore, in some embodiments, the first axial water retaining member 3412 is further provided with a connecting clip 3412a, through which the first axial water retaining member 4312 is connected to the fin bracket 230, thereby improving the installation stability of the first axial water retaining member 3412. It is understood that the location, shape, and number of the connecting clips 3412a are not limited and can be set as needed to meet different connection requirements between the two.

[0053] In some embodiments, the water retaining assembly 340 includes a radial water retaining member 343, which is located on one side of the water pumping wheel 323 in the radial direction and is disposed at one end of the axial water retaining member 340 in the second direction. When the radial water retaining member 343 is installed on the air conditioner base 100, the radial water retaining member 343 is located on an edge of the air conditioner base 100 near the water pumping wheel 323 in the second direction and is disposed adjacent to the heat exchange fins 210 in the second direction, thereby preventing condensed water scattered by the water pumping assembly 320 from splashing outward in the second direction.

[0054] Specifically in one embodiment, the radial water retaining member 343 is a boxed structure, including a radial water retaining body 3432 and a radial water retaining edge 3434. The radial water retaining body 3432 is a flat plate structure arranged perpendicular to the second direction. The radial water retaining edge 3434 extends from the edge of the radial water retaining body 3432 toward the axial water retaining unit 341 and circumferentially surrounds the radial water retaining body 3432, thereby effectively preventing the condensed water scattered by the water-pumping assembly 320 from splashing outward along the second direction.

[0055] Furthermore, a first connecting portion 3436 is protruding from a side edge of the radial water retaining member 343 in the second direction, and a first mounting hole is provided in the first connecting portion 3436. A second mounting hole 3412b is provided at one end of the first axial water retaining member 3412 in the second direction, which is close to the radial water retaining member 343, and corresponds to the first mounting hole. A fastener can pass through the second mounting hole 3412b and the first mounting hole in sequence to connect the radial water retaining member 343 and the first axial water retaining member 3412. A second connecting portion 3438 is protruding from one end of the radial water retaining member 343 in the third direction, which is away from the water receiving trough 100a. The second connecting portion 3438 is provided with a third mounting hole. The fastener can pass through the third mounting hole to be fixed to the fin bracket 230. In this way, the radial water retaining member 343 is detachably connected to the first axial water retaining member 3412 and the fin bracket 230, respectively, thereby having higher installation stability.

[0056] When the water pumping assembly 320 needs to be repaired, the radial water stop 343 and the first axial water stop 3412 can be removed first to form a maintenance port, and the water pumping assembly 320 can be disassembled and repaired without removing the second axial water stop 3414, thereby having high disassembly and assembly convenience.

[0057] In some embodiments, a wiring groove 3432a is defined on the side of the radial water retaining member 343 facing away from the water wheel 323. The wiring groove 3432a extends generally along a first direction to embed and secure a wiring harness passing through the surface. It is understood that the shape, position, and number of the wiring grooves 3432a are not limited and can be configured as needed to meet different wiring requirements.

[0058] The aforementioned water pumping structure 300 and the air conditioner equipped therewith, through the provision of the water retaining assembly 340, can partially close the gap between the heat exchanger and the air conditioner base 100 and effectively wrap the water pumping parts of the water pumping assembly 320, thereby limiting the flight path of the dispersed condensed water to the two heat exchange fins 210, preventing the condensed water from splashing onto other circuits or components of the air conditioner and affecting its normal operation. This fully utilizes the condensed water generated during the operation of the air conditioner to dissipate heat from the heat exchange fins 210, effectively improving the heat exchange efficiency of the heat exchanger and achieving the effect of reducing costs and increasing efficiency. Furthermore, when the water pumping assembly 320 needs to be repaired, there is no need to disassemble the heat exchange fins 210. Simply removing the radial water retaining member 343 and the first axial water retaining member 3412 exposes the water pumping assembly 320 and allows it to be removed from the air conditioner base 100, thereby improving the repairability of the water pumping assembly 320.

[0059] It should be noted that the above embodiments are merely exemplary and do not limit the technical scope of this application. It is understood that in other embodiments, the water retaining structure 300 may also be applied to a separate air conditioning system such as a mobile air conditioner that is only used to adjust the indoor temperature, which is not limited here.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
