An air conditioner 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 4, and the air conditioner 100 may be explicitly installed at the top of a room in a semi-hidden state, is beautiful and convenient to maintain, and can ensure thermal comfort with an increased installation height.

As shown in fig. 1 and 3 to 4, an air conditioner 100 according to an embodiment of the present invention includes: a housing 1, a volute assembly 2, a wind wheel 3 and an indoor heat exchanger 4.

As shown in fig. 3 to 4, an air inlet 11 may be provided on the housing 1, and an air outlet 12 may be provided on the front wall of the housing 1, and indoor air may enter the housing 1 through the air inlet 11, and air flow after heat exchange may enter the indoor space through the air outlet 12.

As shown in fig. 1 and fig. 3-4, the volute assembly 2 may be disposed in the housing 1, the wind wheel 3 may be disposed in the volute assembly 2, the volute assembly 2 may be provided with an air guiding duct 24, and the air flow may circulate in the air guiding duct 24. At least a portion of the indoor heat exchanger 4 may be disposed within the housing 1 and may be located between the air intake 11 and the inlet end of the volute body 21. Specifically, the wind wheel 3 can form negative pressure in the housing 1 by rotating, and under the action of the negative pressure, indoor air can enter the housing 1 through the air inlet 11, and indoor air flow exchanges heat with the indoor heat exchanger 4 in the housing 1. The air flow after heat exchange can enter the volute assembly 2 through the inlet end of the volute body 21, circulate in the air guide duct 24 and sequentially enter the indoor space through the outlet end of the volute body 21 and the air outlet 12.

As shown in fig. 1-2, the volute assembly 2 may include a volute body 21, a volute tongue 22, and a diffuser section 23, the volute tongue 22 may be connected to a lower surface of an outlet end of the volute body 21 and the volute tongue 22 may be rotatable with respect to the volute body 21, the diffuser section 23 may be connected to a front end of the volute tongue 22 to be synchronously rotated by the volute tongue 22, and the diffuser section 23 may have a wind guide section 231 extending obliquely downward.

Specifically, the volute assembly 2 has the effect of directing the air flow. The volute tongue 22 can rotate relative to the volute main body 21, and the volute tongue 22 can drive the diffuser section 23 to rotate while rotating, so that the air outlet direction of the air outlet 12 can be adjusted. For example, as shown in FIG. 1, when the volute tongue 22 is rotated counterclockwise, the air flow may be directed to blow out obliquely upward of the air conditioner 100. When the volute tongue 22 rotates clockwise, the air flow can be directed to blow out obliquely downward of the air conditioner 100. The air guide section 231 may function as an air guide, so that an air guide effect of the volute assembly 2 may be improved.

Alternatively, the wind guide 231 may be inclined at an angle of 0 ° -90 ° with respect to the horizontal direction. For example, when the air conditioner 100 performs a cooling operation, the air guide 231 may be set to have an inclination angle of 0 ° with respect to the horizontal direction, thereby preventing cold air from being directly blown to indoor users and improving the use comfort of the users. When the air conditioner 100 performs a heating operation, the air guide 231 may be provided to have an inclination angle of 60 ° with respect to the horizontal direction, so that hot air may be circulated obliquely downward of the air conditioner 100, thereby ensuring that the hot air may circulate to the indoor floor, and improving the heating effect of the air conditioner 100.

It will be appreciated that the angle and direction of rotation of the volute tongue 22 may be selected based on the actual application requirements. For example, when the installation height of the air conditioner 100 is high, the rotation angle of the volute tongue 22 in the clockwise direction may be appropriately increased. When the installation height of the air conditioner 100 is low, the rotation angle of the volute tongue 22 in the clockwise direction can be properly reduced, and can be flexibly selected according to actual use conditions.

In the specific example shown in fig. 3, when the air conditioner 100 is in the cooling operation mode, since the air density of the cool air is high, in order to prevent the cool air from being directly blown to indoor users, the rotation angle of the volute tongue 22 may be adjusted to control the cool air flow to be blown out in the horizontal direction. Under the action of gravity, the cold air flow can slowly circulate from top to bottom in the indoor space, so that the indoor temperature distribution is more uniform, and a better refrigerating effect can be realized.

In the specific example shown in fig. 4, when the air conditioner 100 is in the heating mode, since the air density of the hot air is low and the circulation speed is low, in order to ensure that the hot air can be blown onto the floor, the volute tongue 22 can be rotated clockwise to incline a certain angle, and the air guiding section 231 can guide the hot air flow to blow out towards the obliquely lower side of the air conditioner 100, so that the hot air flow can smoothly circulate onto the indoor floor, and the use comfort of the user can be improved.

According to the air conditioner 100 of the embodiment of the invention, the rotatable volute tongue 22 is arranged in the volute component 2, and the volute tongue 22 can drive the diffuser section 23 to rotate through rotation so as to adjust the air outlet direction of the air conditioner 100, so that the rotation angle of the volute tongue 22 can be flexibly adjusted according to the actual installation height and the use requirement of the air conditioner 100, and the use flexibility and the use comfort of a user can be improved. The air conditioner 100 has a simple structure, is convenient to operate, has high flexibility in use, and has strong practicality. In particular, when the air conditioner is installed at a height of more than 2.2m, for example, 2.8m, it is possible to blow wind to the ground during heating, thereby contributing to improvement of thermal comfort of the room.

As shown in fig. 1 and 3-4, in some alternative embodiments of the present invention, a rotation guide section 232 may be provided at a lower end of the air guiding section 231, and the rotation guide section 232 may be slidably engaged with an inner bottom wall of the housing 1, so that the operational stability of the volute assembly 2 may be improved. Specifically, when the volute tongue 22 drives the diffuser section 23 to rotate, the rotation guide section 232 can slide relative to the inner bottom wall of the casing 1, so that the operation of the air guide section 231 is smoother, and a better air guide effect can be achieved.

Further, the bottom wall of the housing 1 may be provided with an inclined section 13 extending obliquely forward and upward, and the rotation guide section 232 may be slidably engaged with an inner bottom wall of the inclined section 13, thereby enabling the rotation guide section 232 to be engaged with the bottom wall of the housing 1 more smoothly. In the specific example shown in fig. 2, the rotation guide section 232 is formed in a circular arc shape, a circular arc-shaped engaging portion 13a is provided on the inner bottom wall of the inclined section 13, and the rotation guide section 232 is engaged with the engaging portion 13a in a cambered surface. Thus, by the above arrangement, the fitting of the rotation guide section 232 with the housing 1 can be made smoother.

In some alternative embodiments of the present invention, the rotatable angle of the air guide 231 may be in the range of 0 ° -60 °, thereby improving the air outlet effect of the air conditioner 100. It should be understood that the rotation angle range of the air guiding section 231 is not limited thereto, and the rotation angle range of the air guiding section 231 may be adjusted according to the air outlet requirement of the air conditioner 100.

As shown in fig. 1 and 3-4, according to some embodiments of the present invention, the air conditioner 100 may include an air guide assembly 5 for changing an air outlet direction of the air outlet 12, whereby an air outlet effect of the air conditioner 100 may be improved. In particular, the air guide assembly 5 may function to direct an air flow. For example, when the air conditioner 100 performs a cooling operation, the air guide assembly 5 may be controlled to guide the air flow to flow directly in front of or obliquely above the casing 1. When the air conditioner 100 performs a heating operation, the air guide assembly 5 may be controlled to guide the air flow to circulate obliquely downward of the casing 1.

In the embodiment shown in fig. 3 to 4, the air guiding assembly 5 may include two sets of air guiding plates 51 spaced in the up-down direction, so that the overall structure of the air guiding assembly 5 is simpler and is convenient to install and operate. Specifically, the air deflectors 51 may rotate relative to the housing 1, and the two sets of air deflectors 51 may cooperate with each other to adjust the air outlet direction of the air outlet 12.

For example, as shown in fig. 3, when the air conditioner 100 is in the cooling operation mode, the air guide plate 51 may be controlled to be rotated to a direction perpendicular to the front wall of the housing 1, whereby the air guide assembly 5 may guide the air flow to be blown out in the horizontal direction. Because the air density of cold wind is great, under the effect of gravity, cold air current can flow slowly from top to bottom in indoor space, from this not only can make indoor temperature distribution more even, can also realize the effect of no sense of wind to can promote user's use comfort.

As another example, as shown in fig. 4, when the air conditioner 100 is in the heating operation mode, the air guide plate 51 may be controlled to rotate clockwise and be inclined toward the obliquely lower side of the casing 1, whereby the air guide assembly 5 may guide the air flow to blow out toward the obliquely lower side of the casing 1. Due to the arrangement, the hot air can smoothly circulate to the indoor floor, so that the heating effect of the air conditioner 100 can be improved.

It will be understood that the design of the air guiding assembly 5 is not limited thereto, and the air guiding assembly 5 may also include a plurality of air guiding plates 51 distributed at intervals in the up-down direction, and may be selectively arranged according to the size of the air outlet area of the air outlet 12.

As shown in fig. 1 and 3-4, in some embodiments of the present invention, the air inlet 11 may be provided on the bottom wall of the casing 1, so that the working efficiency of the air conditioner 100 may be improved. It will be appreciated that the air conditioner 100 may be installed on an indoor ceiling, and the air inlet 11 may be provided on the bottom wall of the housing 1 to shorten the circulation distance of the air flow, thereby improving the cooling and heating efficiency of the air conditioner 100.

As shown in fig. 1, 3-4, according to some embodiments of the present invention, the air conditioner 100 further includes a water tray 6, and the indoor heat exchanger 4 may be placed in the water tray 6, thereby facilitating collection and drainage of condensed water. Specifically, when the indoor heat exchanger 4 is in operation, a large amount of condensed water is generated on the surface of the indoor heat exchanger 4, and the water receiving tray 6 can play a role in collecting the condensed water. Alternatively, a water outlet communicating with the water pan 6 may be provided on the housing 1, and a drain pipe may be installed at the water outlet, so that water in the water pan 6 may be led out, and thus normal operation of the air conditioner 100 may be ensured.

In some alternative embodiments of the present invention, the indoor heat exchanger 4 may be vertically placed in the water pan 6, and condensed water on the surface of the indoor heat exchanger 4 may flow into the water pan 6 by gravity, thereby improving drainage efficiency of the indoor heat exchanger 4. It will of course be appreciated that the indoor heat exchanger 4 may also be placed obliquely, optionally depending on the actual installation conditions.

In some optional embodiments of the present invention, the wind wheel 3 may be a centrifugal wind wheel, and the centrifugal wind wheel has the advantages of high running stability, large generated negative pressure value, and the like, so that not only the air supply efficiency of the wind wheel 3 can be improved, but also the working noise of the air conditioner 100 can be reduced, and the use comfort of a user can be improved.

In some embodiments of the present invention, the cross section of the tongue 22 may be formed as an arc, and the tongue 22 may be rotatable around its center, thereby improving the operational stability of the tongue 22, as shown in fig. 2. It will be appreciated that, since the volute tongue 22 is formed in an arc shape, the lower surface of the outlet end of the volute body 21 and the volute tongue 22 can be formed in an arc fit, so that the rotational resistance of the volute tongue 22 can be reduced, and the operation of the volute tongue 22 can be made smoother.

An air conditioner 100 according to an embodiment of the present invention, which may be used in the air conditioner, is described in detail below with reference to fig. 1 to 4. It is to be understood that the following description is exemplary only and is not intended to limit the invention in any way.

As shown in fig. 1 and 3 to 4, an air conditioner 100 according to an embodiment of the present invention includes: the device comprises a shell 1, a volute assembly 2, a wind wheel 3, an indoor heat exchanger 4, an air guide assembly 5 and a water receiving disc 6.

As shown in fig. 3-4, an air inlet 11 is formed in the bottom wall of the housing 1, an air outlet 12 is formed in the front wall of the housing 1, an air guide assembly 5 for changing the air outlet direction of the air outlet 12 is arranged at the air outlet 12, the air guide assembly 5 comprises two groups of air guide plates 51 which are arranged at intervals in the up-down direction, and the two groups of air guide plates 51 can rotate relative to the housing 1.

As shown in fig. 1 and 3-4, the volute assembly 2 is accommodated in the housing 1, the wind wheel 3 is arranged in the volute assembly 2, and the wind guide duct 24 is arranged in the volute assembly 2. As shown in fig. 1-2, the volute assembly 2 includes a volute body 21, a volute tongue 22, and a diffuser 23. The cross section of the volute tongue 22 is circular arc-shaped, and the volute tongue 22 can rotate around the circle center. The diffuser 23 is connected to the front end of the volute tongue 22 to be synchronously rotated by the volute tongue 22, and the diffuser 23 has a downward-inclined air guide section 231. The lower end of the air guiding section 231 is provided with a rotation guiding section 232, the bottom wall of the shell 1 is provided with an inclined section 13 extending forwards and upwards in an inclined mode, and the rotation guiding section 232 is in sliding fit with the inner bottom wall of the inclined section 13.

Specifically, when the air conditioner 100 performs the heating operation, since the air density of the hot air is small and the circulation speed is slow, in order to ensure that the hot air can be blown onto the floor, the volute tongue 22 and the air deflector 51 may be rotated clockwise, and the air guide section 231 and the air deflector 51 may guide the hot air flow to blow out toward the obliquely lower side of the casing 1, thereby enabling the hot air flow to smoothly circulate onto the floor in the room and improving the use comfort of the user.

When the air conditioner 100 is in the cooling operation mode, since the air density of the cool air is high, in order to prevent the cool air from being directly blown to indoor users, the rotation direction and rotation angle of the volute tongue 22 and the air guide assembly 5 may be adjusted, so that the cool air flow may be controlled to be blown out in the horizontal direction. Under the action of gravity, the cold air flow can slowly circulate from top to bottom in the indoor space, so that the indoor temperature distribution is more uniform, and a better refrigerating effect can be realized.

The volute tongue 22 may be rotated clockwise to incline obliquely downward of the casing 1 when the installation height of the air conditioner 100 increases, and the volute tongue 22 may be rotated clockwise when the installation height of the air conditioner 100 decreases. Thus, through the above arrangement, the volute tongue 22 can cooperate with the air guide assembly 5 to circulate the air flow with the heat exchanged to the indoor floor, so that the cooling and heating effects of the air conditioner 100 can be improved.
