Detailed Description

An air conditioner indoor unit 10 according to an embodiment of the present disclosure is described below with reference to fig. 1 to 5. In the description of the present disclosure, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise. When a feature "comprises or comprises" a or some of its intended features, this indicates that other features are not excluded and that other features may be further included, unless expressly stated otherwise.

Fig. 1 is a schematic structural view of an air conditioner indoor unit 10 according to an embodiment of the present invention.

The indoor unit 10 is the indoor portion of a split-room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like. The technical scheme of the utility model can be applied to wall-hanging air conditioner indoor unit 10 or floor air conditioner indoor unit 10, but is not limited to this. The following will explain the technical solution of the present invention in detail by taking the case that the air conditioner indoor unit 10 is a wall-mounted air conditioner indoor unit 10 as an example. On the basis of understanding the following embodiments, those skilled in the art should easily extend the embodiments to other models of the air conditioner indoor unit 10, and the detailed description of the disclosure is omitted.

Fig. 2 is a schematic view of the internal structure of the indoor unit 10 of the air conditioner shown in fig. 1, in which a part of the casing 100, for example, the cover 102, is hidden. Fig. 3 is a schematic exploded view of the internal structure of the indoor unit 10 of the air conditioner shown in fig. 2. Fig. 4 is a partially enlarged view of a portion a in fig. 3. As shown in fig. 1 to 4, the indoor unit 10 of the present invention may generally include a casing 100, an air supply fan 200 and a humidity adjustment assembly 300.

The interior of the cabinet 100 defines an air duct 110. The air duct 110 serves to define a flow path of the supply air flow. For example, the casing 100 may be opened with an air inlet 140 and an air outlet 150 communicating with an external environment (i.e., an indoor environment), and the air duct 110 is formed between the air inlet 140 and the air outlet 150.

The air supply fan 200 is disposed in the air duct 110, and is configured to promote outside air to flow into the casing 100 and flow out of the casing 100 after flowing through the air duct 110, and form a negative pressure airflow activity region 120 for negative pressure airflow activity in the casing 100. When the airflow passes through the air duct 110, a negative pressure is generated in the space near the air duct 110, which results in a negative pressure airflow active region 120 in the space. When the airflow passes through the air duct 110, the air in the negative pressure airflow active region 120 forms a negative pressure airflow under the action of the negative pressure, and flows toward the air duct 110 to mix with the supply airflow.

The humidity adjustment assembly 300 is disposed in the cabinet 100, and has a moisture enrichment part 310. The moisture enrichment part 310 is disposed in the negative pressure airflow active region 120, and is used for enriching moisture when the air supply blower 200 operates, so as to release moisture to the negative pressure airflow passing through it. For example, the moisture enrichment part 310 may have a water absorbing material to enrich moisture. Because the moisture enrichment part 310 can enrich moisture, when the negative pressure airflow flows through the moisture enrichment part 310, the moisture enrichment part 310 is caused to separate from the moisture enriched by the moisture enrichment part, so that the negative pressure airflow carries the moisture to form a high humidity airflow. These high humidity streams may mix with the supply air stream, thereby increasing the humidity of the supply air stream.

In the air conditioner indoor unit 10 of the present embodiment, since the humidity adjustment assembly 300 is disposed in the casing 100, and the humidity adjustment assembly 300 has the moisture enrichment part 310 disposed in the negative pressure airflow active region 120, when the air supply fan 200 operates, the negative pressure airflow active region 120 can be prompted to form a negative pressure airflow, and the negative pressure airflow can flow through the moisture enrichment part 310 to carry moisture. By adopting the scheme of the embodiment, the air conditioning effect of the air conditioner indoor unit 10 can be optimized, so that the air conditioner indoor unit 10 has a humidifying function, and the indoor air is favorably reduced or prevented from being too dry.

Because the moisture-enriching part 310 is disposed in the negative pressure airflow active region 120, the air conditioner indoor unit 10 can rely on the negative pressure generated by the operation of the air supply fan 200 to form a high humidity airflow and send the high humidity airflow out of the casing 100, thereby achieving the air humidifying effect without installing other atomizing mechanisms, facilitating the simplification of the structure of the air conditioner indoor unit 10, reducing the volume and lowering the manufacturing cost.

The negative pressure airflow active region 120 may be located at a side of the blower fan 200, and may be optionally disposed at a side of the air duct 110. The negative airflow active region 120 may be configured such that the supply airflow flowing from the inlet 140 into the air duct 110 and flowing from the outlet 150 out of the air duct 110 hardly flows through the negative airflow active region 120.

The positions of the air inlet 140 and the air outlet 150 can be set according to actual needs as long as the air duct 110 is ensured to be smooth. For example, the inlet 140 may be opposite to the inlet end of the blower fan 200, and the outlet 150 may be opposite to the outlet end of the blower fan 200. In some alternative embodiments, as shown in fig. 1, when the indoor unit 10 is a wall-mounted indoor unit, the air inlet 140 is located at the top of the casing 100, and the air outlet 150 is located at the lower front portion of the casing 100.

The air conditioner indoor unit 10 of the present disclosure may perform cooling or heating using a vapor compression refrigeration system. A heat exchanger 400 may be further provided in the cabinet 100 of the indoor unit 10 of the air conditioner. The heat exchanger 400, the throttle device, and a compressor, a condenser, and other refrigeration components provided in the outdoor unit of the air conditioner are connected through pipes to form a vapor compression refrigeration cycle system. Under the action of the air supply fan 200, the indoor air enters the casing 100 through the air inlet 140 of the casing 100 and flows through the air duct 110, after the forced convection heat exchange with the heat exchanger 400 is completed, the air supply flow is formed, and then the air is blown to the air outlet 150 under the guidance of the air duct 110. The heat exchanger 400 may be, for example, a three-stage heat exchanger, or a two-stage heat exchanger.

In some alternative embodiments, an air inlet section located upstream of the heat exchanger 400 and an air outlet section located downstream of the heat exchanger 400 and a heat exchange section where the heat exchanger 400 is located may be formed between the air inlet 140 and the air outlet 150. The air inlet section, the heat exchange section and the air outlet section form an air duct 110. When the intake vent 140 is located at the top of the casing 100, the heat exchanger 400 may be a plate heat exchanger 400, and is located inside the intake vent 140 and above the blower fan 200. The moisture enrichment part 310 may be disposed at one lateral side of the air supply fan 200. With this arrangement, the high-humidity airflow formed in the negative-pressure airflow active region 120 hardly flows through the heat exchanger 400, and the humidity can be maintained to a large extent, thereby exhibiting a good air humidification effect.

In some optional embodiments, as shown in fig. 1, the casing 100 may be provided with a negative pressure air port 130 communicating with an external environment. Indoor air can flow into the negative pressure airflow active region 120 from the negative pressure air opening 130, thereby becoming a part of the negative pressure airflow and increasing the airflow rate of the negative pressure airflow. The negative pressure airflow active region 120 is located inside the negative pressure tuyere 130 and is communicated with the negative pressure tuyere 130.

It should be noted that the directions or positional relationships indicated by the terms "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. are based on the directions or positional relationships shown in the drawings or based on the actual use state of the indoor unit 10 of the air conditioner, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

The negative pressure airflow active region 120 is located inside the negative pressure air opening 130, which means that the airflow from the environment outside the enclosure 100 enters the interior of the enclosure 100 through the negative pressure air opening 130 and then flows through the negative pressure airflow active region 120. By additionally forming the negative pressure air inlet 130 on the casing 100, the air flow passing through the negative pressure airflow active region 120 can be increased.

When the negative pressure air opening 130 for communicating the external environment with the negative pressure air flow active region 120 is formed in the casing 100, under the condition that the air supply fan 200 is operated, a large amount of air from the external environment of the casing 100 can enter the negative pressure air flow active region 120 from the negative pressure air opening 130 and flow through the moisture enrichment part 310, so that the flow rate of high humidity air flow can be increased when the air supply fan 200 is operated by the indoor unit 10 of the air conditioner, and the humidification effect of the indoor unit 10 of the air conditioner is improved.

The positions of the negative pressure air opening 130 and the negative pressure airflow active region 120 can be set according to actual needs, as long as it is ensured that the negative pressure airflow active region 120 can be communicated with the external environment of the enclosure 100 through the negative pressure air opening 130. For example, the negative pressure air port 130 can be configured to communicate the negative pressure airflow active region 120 from the top, bottom, front, back, or sides thereof to the environment outside of the enclosure 100.

In some alternative embodiments, as shown in fig. 1, the negative pressure tuyere 130 may be located at one lateral end of the casing 100. Accordingly, the negative pressure airflow active region 120 is located inside the negative pressure tuyere 130 and is adjacent to the negative pressure tuyere 130.

The air duct 110 is disposed inside the negative pressure airflow active region 120 and is parallel to the negative pressure airflow active region 120 along the transverse direction of the enclosure 100. That is, the casing of the casing 100 is provided with the negative pressure air opening 130, the negative pressure airflow active region 120 and the air duct 110 in sequence from outside to inside along the transverse extending direction of the casing 100.

The blowing fan 200 is a cross-flow fan whose rotation axis is parallel to the lateral direction of the casing 100. When the air supply fan 200 is operated, negative pressure is formed in regions at both lateral sides of the air supply fan 200, thereby generating negative pressure air flow.

By adopting the structure, the negative pressure generated in the operation process of the air supply fan 200 can be fully utilized to form high-humidity negative pressure airflow, so that the humidity of the air supply airflow is improved. And the air conditioner indoor unit 10 can mount the humidity adjusting assembly 300 into the cabinet 100 without increasing the thickness and width of the cabinet 100, so that the air conditioner indoor unit 10 can add a humidifying function without significant appearance change.

The moisture enrichment part 310 may be provided as any component or member capable of enriching and releasing moisture, for example, in some embodiments, the moisture enrichment part 310 may include a water absorption cloth made of a water absorption material, or the like. Alternatively, the water absorbent material may be provided with breathability. The humidity adjustment assembly 300 may be further provided with a water source, and the moisture enrichment part 310 may be configured to reciprocate between a position close to the water source and a position far from the water source when the air blower 200 is operated, thereby periodically enriching and releasing moisture.

In some alternative embodiments, as shown in fig. 2-4, the moisture enrichment part 310 may be an impeller that enriches moisture and releases moisture by rotating around a shaft. That is, the moisture enrichment part 310 of the present embodiment is controlled to be pivotably disposed. When the moisture-enriched portion 310 rotates, the enriched moisture is thrown out by centrifugal motion, and is released into the negative pressure airflow flowing through, so as to form a high humidity airflow.

With the above structure, the moisture-enriched part 310 can easily release moisture to the negative pressure airflow flowing through the moisture-enriched part based on the rotation around the shaft, so as to improve the humidity of the negative pressure airflow flowing through the moisture-enriched part 310 and obtain high air humidification efficiency.

In the present embodiment, the moisture enrichment section 310 may generally include a hub 311 and at least one blade 312. The hub 311 is provided with a shaft hole (not shown) penetrating along the thickness direction thereof, so that the driving shaft 313 of the moisture enrichment part 310 can pass through the shaft hole. The blades 312 are formed to extend radially outward from the outer circumferential surface of the hub 311. The blades 312 are provided with a water absorbing material (not shown) such as a water absorbing cloth or the like for enriching water. The position of the driving shaft 313 of the moisture-enriched portion 310 relative to the hub 311 is a shaft hole, which is not marked in the drawing.

The humidity conditioning assembly 300 further includes a moisture supply portion 320 including a water storage means 321 for containing moisture and having a top opening 321 a. For example, the water storage device 321 may be a water storage tank.

The moisture enrichment part 310 is disposed above the moisture supply part 320 and allows at least a portion thereof to protrude into the water storage means 321 from the top opening 321a when pivoting. For example, the moisture enrichment part 310 allows the blades 312 to protrude into the water storage means 321 from the top opening 321a when rotating around the axis. That is, the blades 312 of the moisture enrichment part 310 may extend into the water storage 321 from the top opening 321a of the water storage 321 to contact with the moisture contained in the water storage 321, so as to absorb and enrich the moisture.

The moisture supply part 320 may be fixed in the cabinet 100, for example, a wall of the water storage 321 may be fixedly connected to an inner wall of the cabinet 100. Fixed attachment means include, but are not limited to, threading, welding, bonding, and snapping.

In some alternative embodiments, the enclosure 100 includes a skeleton 101 and a cover 102 assembled to each other. The moisture supply part 320 further includes a mounting plate 322 fixedly connected to or integrated with the wall of the water storage means 321 and having a connection part for fixedly connecting with the framework 101. That is, the water storage 321 may be indirectly fixed in the cabinet 100 by the mounting plate 322.

For example, mounting plate 322 may include first vertical plate 322a, second vertical plate 322b arranged at intervals in a lateral direction of cabinet 100, first connecting plate 322c connected to a top of first vertical plate 322a and a top of second vertical plate 322b, and second connecting plate 322d connected between a rear end of first vertical plate 322a and a rear end of second vertical plate 322b, thereby defining a channel having a front opening. The first vertical plate 322a and the second vertical plate 322b are respectively parallel to the front-rear extension direction of the cabinet 100, and are respectively connected to the rear ends of the two side walls at the two lateral ends of the water storage device 321 one by one. Second upright plate 322b is positioned inboard of first upright plate 322 a.

Fig. 5 is a schematic structural diagram of an air conditioner indoor unit 10 according to another embodiment of the present invention, which is a schematic diagram of a rear side view angle of the air conditioner indoor unit 10. As shown in fig. 5, the coupling portion may be provided on an outer surface of second vertical plate 322b of mounting plate 322. The connection part may include a first connection member 322e and a second connection member 322f protruding from an outer surface of the second vertical plate 322b toward the inside of the cabinet 100. The frame 101 is correspondingly formed with a first engaging portion and a second engaging portion fixedly connected to the first connecting member 322e and the second connecting member 322f, respectively. For example, the first connecting member 322e can be a claw, and the first mating portion can be a slot, so that the first connecting member 322e can extend into the slot and achieve a snap fit. The second connecting member 322f may be plate-shaped and have an opening, the second mating portion may be a threaded hole, and the second connecting member 322f and the second mating portion may be fixedly connected by a screw passing through the opening of the second connecting member 322f and screwing into the threaded hole.

With the above structure, the moisture supply unit 320 can be flexibly disassembled according to actual needs, and the operation difficulty of the disassembling process is low, which is beneficial to reducing the maintenance cost of the indoor unit 10 of the air conditioner.

The number of blades 312 may be one, two, or more. In some embodiments, as shown in fig. 2 and 3, the blades 312 are multiple and evenly distributed along the circumferential direction of the hub 311. The hub 311 may have a substantially cylindrical shape, and an outer peripheral surface thereof may be a cylindrical side surface.

When a part of the blades 312 extend into the water storage 321 to enrich water, another part of the blades 312 can release water. The plurality of blades 312 alternately "enrich" and "release" the moisture, facilitating the continuous formation of a high humidity air flow with uniform humidity.

The angle between the surface of each blade 312 and the thickness direction of the hub 311 is 0 °. The thickness direction of the hub 311 is parallel to the height direction of the column of the hub 311. Since the driving rotation shaft 313 of the moisture enrichment part 310 passes through the shaft hole of the hub 311, when the negative pressure airflow passes through the blades 312 in the thickness direction of the hub 311, the blade surfaces of the blades 312 are parallel to the flow direction of the negative pressure airflow, and the blade surfaces hardly block the negative pressure airflow.

When the moisture enrichment part 310 is provided with a plurality of blades 312, and the included angle between the blade surface of each blade 312 and the thickness direction of the hub 311 is 0 °, the airflow can naturally flow along the blade surface of the blade 312 and hardly bends the path, which is beneficial to reducing the wind resistance, and the airflow can fully contact with each blade 312 of the moisture enrichment part 310, the contact area is large, the airflow flowing through the blades 312 can carry more moisture, and the humidifying effect is further improved.

The shape of the blade 312 can be set according to actual needs, and for example, it can be circular, square, triangular or other irregular shape.

In some alternative embodiments, as shown in fig. 4, the blade 312 has a first blade rim 312a and a second blade rim 312b arranged at intervals in the thickness direction of the hub 311, and a connection She Biankuang c connected between the first blade rim 312a and the second blade rim 312b, so that the blade 312 defines an in-frame area 312d for installing the water absorbing material. The in-frame region 312d is collectively enclosed and defined by a first leaf rim 312a, a second leaf rim 312b, and a connection She Biankuang c. An absorbent material such as absorbent cloth may be attached to the framed interior area 312d by gluing, tying, or sewing, which is not shown in the drawings.

In some further embodiments, a connection She Biankuang c may be connected between the top of the first blade rim 312a and the top of the second blade rim 312b to enlarge the in-frame area 312d as much as possible, increasing the water uptake of the individual blade 312.

The humidity adjustment assembly 300 may further include a bracket extending upward from a sidewall of the water storage 321 of the moisture supply part 320 and having a fitting hole into which the driving rotation shaft 313 of the water supply part 310 is fitted to rotatably fit, thereby supporting the moisture enrichment part 310.

In some alternative embodiments, as shown in fig. 2-4, the thickness direction of the hub 311 is parallel to the lateral direction of the casing 100.

The humidity adjustment assembly 300 further includes a driving motor 330, and an output shaft of the driving motor 330 is fixedly connected to the driving rotation shaft 313 of the moisture enrichment part 310, or is inserted into a shaft hole of the hub 311 and serves as the driving rotation shaft 313. The driving motor 330 of the present embodiment may be a micro stepping motor. When the air conditioner indoor unit 10 starts the humidifying function, the driving motor 330 is controlled to be started to drive the moisture enriching part 310 to rotate, thereby circulating the blade 312 between the moisture enriching position and the moisture releasing position.

The inner wall of the housing 102 of the casing 100 may be formed with a groove for the driving motor 330 to be at least partially assembled therein, so as to fix the driving motor 330, and thus the driving motor 330 is assembled to the casing 100, thereby improving the structural stability of the whole air conditioner indoor unit 10.

In the air conditioner indoor unit 10 of the above embodiment, since the humidity adjustment assembly 300 is disposed in the casing 100, and the humidity adjustment assembly 300 has the moisture enrichment part 310 disposed in the negative pressure airflow active region 120, when the air supply fan 200 operates, the negative pressure airflow active region 120 can be prompted to form a negative pressure airflow, and the negative pressure airflow can flow through the moisture enrichment part 310 to carry moisture. Adopt the utility model discloses a scheme can optimize the air conditioning effect of air conditioner 10, makes air conditioner 10 possess the humidification function, is favorable to reducing or avoids the room air too dry.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
