Description

Air conditioner

Technical Field

The application relates to the technical field of air conditioners, in particular to an air conditioner.

Background

At present, the functions of the air conditioner are more and more abundant. Because the vertical air conditioner is large in size, the air conditioner with the purification function is favored by wide consumers in the market.

In order to realize the purification function of the air conditioner, a purification water tank is an indispensable component. After the purifying water tank is used for a plurality of times, the purifying water tank needs to be detached from the air conditioner for cleaning. When the air conditioner is used for purifying air, air flows into the purifying water tank and then flows into the fan. After the purification water tank is disassembled for many times, the gap between the purification water tank and the fan is enlarged, the air flow cannot flow into the fan completely after passing through the outlet of the purification water tank, and part of the air flow can flow out through the gap between the purification water tank and the fan, so that the efficiency of air purification is reduced.

Disclosure of Invention

The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed embodiments. This summary is not an extensive overview, and is intended to neither identify key/critical elements nor delineate the scope of such embodiments, but is intended as a prelude to the more detailed description that follows.

The embodiment of the disclosure provides an air conditioner, which ensures that air flow passing through a purification water tank flows to a fan as completely as possible, reduces the loss of the air flow and improves the air purification efficiency.

In some embodiments, the air conditioner includes: the top of the purification water tank is provided with an air outlet; the air duct assembly is provided with an air inlet; the windward component is arranged on the windward side of the air inlet; the air outlet assembly is arranged at the air outlet side of the air outlet and the bottom of the windward assembly, and the air outlet assembly and the windward assembly are overlapped along the air flow direction under the condition that the air outlet is communicated with the air inlet.

The air conditioner provided by the embodiment of the disclosure can realize the following technical effects:

firstly, air flows out through the air outlet side of the air outlet component when passing through the purifying water tank, flows in through the windward side of the air inlet of the windward component, then enters the cross flow fan, and finally flows out from the outlet of the air channel component. Because the air outlet component is overlapped with the windward component, the air flow is limited in the airtight space formed by the air outlet component and the windward component. Meanwhile, the air outlet component and the windward component are arranged along the direction of the air flow, when the air flow enters the sealed space, all or nearly all the air flows along the direction vertical to the top of the purifying water tank, and the air flow flowing out of the sealed space is smaller. Therefore, the device effectively reduces the air flow loss and improves the air purification efficiency.

1-2, wherein FIG. 1 is a longitudinal cross-sectional view as shown in FIG. 2. The embodiment of the disclosure provides an air conditioner, which comprises a purified water tank 1, an air duct assembly 2, a windward assembly 3 and an air outlet assembly 4. The top of the purified water tank 1 is provided with an air outlet 1a. The air duct assembly 2 is provided with an air inlet 2a. The windward component 3 is disposed on the windward side of the air inlet 2a. The air outlet assembly 4 is arranged at the air outlet side of the air outlet 1a and at the bottom of the windward assembly 3, and the air outlet assembly 4 and the windward assembly 3 are overlapped along the air flow direction under the condition that the air outlet 1a is communicated with the air inlet 2a. Wherein the stacking fingers are arranged in a stacked manner.

Therefore, when the air flow passes through the purification water tank, the air flows out through the air outlet side of the air outlet component, flows in through the windward side of the air inlet of the windward component, then enters the cross flow fan, and finally flows out from the outlet of the air channel component. Because the air outlet component is overlapped with the windward component, the air flow is limited in the airtight space formed by the air outlet component and the windward component. Meanwhile, the air outlet component and the windward component are arranged along the direction of the air flow, when the air flow enters the sealed space, all or nearly all the air flows along the direction vertical to the top of the purifying water tank, and the air flow flowing out of the sealed space is smaller. Therefore, the device effectively reduces the air flow loss and improves the air purification efficiency. In addition, parameters affecting the operation of the cross-flow fan are flow and wind pressure. The device has small air flow loss, so that all or nearly all air enters the cross flow fan, thereby improving the operation efficiency of the cross flow fan.

Alternatively, fig. 2 and 5 are combined, wherein fig. 5 shows a corresponding isometric view of the bottom of the housing 21. The air duct assembly 2 includes a housing 21 and a cross flow fan 22. The lower part of the housing 21 is an opening 21a, and the opening 21a serves as an air inlet 2a. The cross flow fan 22 is fixedly arranged in the shell 21, and the air inlet 2a is arranged below the cross flow fan 22. Wherein, windward component 3 is disposed below air inlet 2a. Therefore, the through-flow fan makes air flow out from the air outlet side of the air outlet and then enter the windward side of the air inlet in an air suction mode, and directly flows to the through-flow fan from the windward side of the air inlet, so that the operation efficiency of the through-flow fan is improved.

Alternatively, as shown in connection with fig. 2 and 7, the purge tank and windward assembly are shown in perspective in fig. 7. The windward component 3 comprises an annular portion 31. The annular portion 31 abuts against the bottom of the housing 21 in the circumferential direction of the housing 21. Therefore, the tightness of the windward component is improved, and meanwhile, the windward component is abutted against the bottom of the shell along the circumferential direction of the shell, so that a gap between the windward component and the shell is as small as possible, and the tightness between the windward component and the shell is improved.

Alternatively, as shown in connection with fig. 2-4, the air outlet assembly 4 is fixedly arranged on top of the clean water tank 1. The air outlet assembly 4 comprises a first baffle 41 and a second baffle 42. The first baffle 41 is located on the inner side of the cross-flow fan 22 and abuts against the inner wall of the annular portion 31. The second baffle 42 is located outside the cross-flow fan 22, abuts against the outer wall of the annular portion 31, and forms an annular structure after being enclosed with the first baffle 41. Like this, the leakproofness between first baffle and the annular portion is better, simultaneously, and second baffle and the annular portion leakproofness are better to improved the leakproofness between air-out subassembly and the windward subassembly.

Optionally, a cover plate 11 is arranged on top of the clean water tank 1. A schematic perspective view of the cover plate 11 is shown in fig. 4. An air outlet component 4 is fixedly arranged above the cover plate 11. The cover plate 11 is provided with an air outlet 1a.

Optionally, the air outlets 1a are waist-shaped holes and are distributed in the cover plate 11 in an array. Therefore, the air outlet has a flow dividing function on the air flow, so that the air flow is divided into a plurality of sections and flows into the air inlet, the air flow and the cross flow fan have larger contact area, and the air flow rate of the cross flow fan is improved.

Alternatively, as shown in connection with fig. 4, the first baffle 41 is a U-shaped plate, and the second baffle 42 is an arc-shaped plate. Like this, the laminating degree of first baffle, second baffle and annular portion is better to the leakproofness of windward subassembly and air-out subassembly has been improved.

Alternatively, the first baffle 41 includes a first wall surface 41a, a second wall surface 41c, and a third wall surface 41b. The first wall surface 41a and the second wall surface 41c are disposed adjacent to each other, and the second wall surface 41c and the third wall surface 41b are disposed adjacent to each other. The first wall surface 41a is perpendicular to the cover plate 11. The second wall surface 41c is perpendicular to the cover plate 11. The third wall surface 41b is perpendicular to the cover plate 11. When the air flow flows into the airtight space through the windward side of the windward component air inlet, the first wall surface, the second wall surface and the third wall surface are perpendicular to the cover plate, the arrangement direction of the first baffle is approximately the same as the air flow direction, the air flow is prevented from entering a gap between the first baffle and the first vertical plate, and the loss of the air flow is reduced.

Optionally, the second baffle 42 is disposed outside the cross-flow fan 22. Thus, when the purge tank needs to be removed, the purge tank can be removed from the air conditioner in a direction away from the cross flow fan.

Alternatively, as shown in connection with fig. 8, the annular portion 31 includes a first riser 311 and a second riser 312. The first vertical plate 311 is located at the inner side of the cross-flow fan 22, and the first baffle 41 abuts against the inner wall of the first vertical plate 311. The second vertical plate 312 is located outside the cross-flow fan 22, and the second baffle 42 abuts against the outer wall of the second vertical plate 312.

Optionally, the annular portion 31 further comprises a third riser 313 and a fourth riser 314. The third riser 313 is located between the first riser 311 and the second riser 312. The fourth riser 314 is located between the first riser 311 and the second riser 312. The third standing plate 313 abuts against the first wall surface 41a of the first barrier 41. The fourth riser 314 abuts against the second wall surface 41c of the first barrier 41. In this way, the first, third, second and fourth standing plates 311, 313, 312 and 314 form a ring-shaped structure, improving sealability of the ring-shaped portion.

Optionally, one end of the cross-flow fan 22 is fixedly disposed on the third vertical plate 313, and the other end is fixedly disposed on the fourth vertical plate 314. Therefore, the third vertical plate and the fourth vertical plate can also play a role in fixing the cross-flow fan on the basis of forming an annular structure with the first vertical plate and the second vertical plate.

Optionally, the third upright 313 is provided with a recess 313a. A driving motor (not shown) is provided in the recess 313a.

Optionally, the third upright 313 is provided with a first fixing hole 313b. The fourth riser 314 is provided with a second fixing hole 314a. The first fixing hole 313b is disposed opposite to the second fixing hole 314 b. One end of the cross flow fan 22 is fixed in the first fixing hole 313b and electrically connected to the driving motor. The other end of the cross flow fan 22 is fixed in the second fixing hole 314 b.

Alternatively, as shown in connection with fig. 2, the X direction indicates the removal direction of the purge tank. The lower edge of the second vertical plate 312 is higher than the upper edge of the first baffle 41. Thus, the second vertical plate and the first baffle plate have a height difference. When the purification water tank needs to be moved out of the air conditioner, as the second vertical plate and the first baffle are provided with the height difference, the air outlet component fixedly arranged at the top of the purification water tank moves along the purification water tank in the process of moving out of the purification water tank along the plane where the cover plate is positioned, and the second vertical plate cannot block the first baffle, so that the windward assembly plate cannot block the air outlet component, and the purification water tank can be smoothly moved out. Therefore, by the design of the height difference between the second vertical plate and the first baffle, the purified water tank can be smoothly moved out of the air conditioner on the basis of reducing the air flow loss.

Alternatively, as shown in fig. 8, the ring-shaped portion 31 has a three-dimensional structure, and the first standing plate 311 includes a support plate 311a. The support plate 311a is plate-shaped, and the housing 21 overlaps the support plate 311a. Therefore, the bearing plate is lapped on the shell due to gravity, the gap between the bearing plate and the shell is as small as possible, and meanwhile, the bearing plate is of a plate-shaped structure, occupies small space and cannot block the airflow.

Alternatively, the housing 21 may be configured in a three-dimensional manner as shown in fig. 5 and 6, with fig. 6 showing a corresponding isometric view of the top of the housing 21. The housing 21 includes a bracket 211 and a first step 212. The bottom of the bracket 211 abuts against the top of the support plate 311a. The first step 212 is located on the side of the support, which is opposite to the cross-flow fan 22, and the outer wall of the support plate abuts against the inner wall of the first step 212. In this way, the first step portion is firmly abutted against the inside of the first step portion, so that the stability between the first vertical plate and the housing is improved.

Optionally, a limiting rib 211a is disposed on the outer wall of the bracket 211. The bottom of the limiting rib 211a is fixedly arranged at the top of the first step portion 212. Therefore, the limiting ribs have supporting effect on the support, and the strength of the support is improved.

Optionally, the limiting ribs 211a are distributed on the outer wall of the bracket 211 in an array. In this way, the strength of the stent is further increased.

Optionally, the limiting ribs 211a are uniformly distributed on the outer wall of the bracket 211.

Alternatively, as shown in conjunction with fig. 8, the first standing plate 311 further includes a second stepped portion 311b. The second step portion 311b is located at a side of the support plate 311a facing away from the cross-flow fan 22, and the bottom of the first step portion 212 abuts against the top of the second step portion 311b. Therefore, the second step part and the first step part are of a structure which enables the tightness between the first vertical plate and the shell to be better, and meanwhile, the shell is firmly lapped on the first vertical plate.

Optionally, the first upright plate 311 further includes a stop strip 311c. The stop strip 311c is disposed on the outer wall of the support plate 311a. The bottom of the stop strip 311c abuts against the top of the second step 311b. The outer wall of the stop strip 311c abuts against the inner wall of the first step 212. Thus, after the first step part of the shell is abutted against the second step part, the shell and the first vertical plate are prevented from shaking, and the stability between the first vertical plate and the shell is improved.
