The shapes of the first air outlet and the second air outlet can be circular, elliptical, square or polygonal, and there is no specific limitation here.

There are many ways for the front panel 220 to be slidably installed on the housing body 110. For example, the front panel 220 can be slidably installed on the housing body 110 through a rack-and-pinion engagement, or can be matched with a slide rail through a pulley. installed on the shell body 110 in a manner. When the front panel 220 opens the first air outlet, the wall-mounted indoor unit can choose the normal air outlet mode or the multi-sided air outlet mode; when the front panel 220 covers the first air outlet, since the A plurality of ventilation holes 221 are opened, so that the wind speed of the air outlet airflow can be reduced, so as to realize the windless air outlet effect of the wall-mounted indoor unit.

The front panel 220 is provided with a plurality of ventilation holes 221 , wherein the shape of the ventilation holes 221 may be circular holes, square holes, triangular holes or strip holes, which are not specifically limited here. A circular hole will be used as an example for description below. The ventilation holes 221 can be arranged in various ways. For example, the ventilation holes 221 can be arranged vertically to the surface of the front panel 220 , or inclined upward or downward.

In addition, there may be various distribution forms of the plurality of ventilation holes 221 on the front panel 220 . In one embodiment, in order to make the air flow from the front side of the wall-mounted indoor unit more uniform, the diameter of the ventilation hole 221 in the middle of the front panel 220 can be made larger than that of the two ends of the front panel 220.

Further, a mounting frame 310 (as shown in FIG. 5 ) for mounting the guiding fan 300 is provided in the casing 100 . Specifically, an accommodating cavity is formed between the mounting frame 310 and the corresponding side panel 230, and the guiding fan 300 is used to guide the external airflow from the second air outlet into the accommodating cavity. And further lead into the air outlet channel 610.

Wherein, the guiding fan 300 may be a steering fan. For example, the guide fan 300 can rotate forward and backward, when the guide fan 300 rotates forward, the external airflow can be introduced into the air outlet channel 610 from the second air outlet; when the guide fan 300 is reversed, The airflow in the air outlet channel 610 can be led out from the second air outlet. In this embodiment, the wall-mounted indoor unit further includes an electric control board connected to the guiding fan 300 to control the forward rotation and reverse rotation of the guiding fan 300 .

When the wall-mounted indoor unit is working, the wind wheel 500 drives the intake air to enter the casing 100 from the air inlet 121. The flow is blown toward the outlet channel 610 to form an outlet airflow. When the guide fan 300 rotates forward (the wall-mounted indoor unit is in the first use state), the indoor air is introduced into the air outlet channel 610 from the second air outlet, and is exchanged with the air in the air outlet channel 610. The airflow is mixed, and the temperature of the mixed airflow is moderate, which improves the comfort of the user. When the guide fan 300 is reversed (the wall-mounted indoor unit is in the second use state), the airflow in the air outlet channel 610 will flow out from the second air outlet, thereby realizing the multi-faceted outlet of the wall-mounted indoor unit. Wind, specifically, the heat-exchanged air outlet airflow forms a plurality of small airflows at the end of the air outlet channel 610, wherein the first airflow (shown as I in the figure) is blown forward through the first air outlet, The second airflow (shown as II in the figure) is blown out laterally through the second air outlet on the cover plate 140 on one side, and the third airflow (as shown in III in the figure) is blown out through the second air outlet on the cover plate 140 on the other side. The second air outlet blows out sideways. In this way, the multi-faceted air outlet of the wall-mounted indoor unit is realized, thereby effectively preventing the air outlet from blowing directly to the user.

In the technical solution of the present invention, by installing the guide fan 300 on both sides of the air outlet channel 610 and corresponding to the second air outlet, when the wall-mounted indoor unit is working, the indoor air is drawn from the The above-mentioned second air outlet leads into the air outlet channel 610 and mixes with the heat-exchanged airflow in the air outlet channel 610. Since the temperature of the airflow after heat exchange is too high or too low, directly blowing to the user will result in poor user experience , and the mixed airflow can effectively average the airflow temperature, so that the mixed airflow will not be too high or too low, so the user feels better. At the same time, by controlling the guide fan 300 to run forward and reversely, the external airflow is introduced from the second air outlet, or the internal airflow is exported from the second air outlet. Specifically, when the guide fan 300 rotates forward, the indoor air is introduced into the air outlet channel from the second air outlet, mixed with the heat-exchanged airflow and then blown to the user, which is beneficial to improve the use efficiency of the user. comfort. When the guide fan 300 is reversed, the airflow in the air outlet channel can be led out from the second air outlet, so as to realize the multi-faceted air outlet of the wall-mounted indoor unit, so that the wind speed of the air outlet airflow is reduced. Smaller and softer, thereby avoiding the concentrated blowing of the airflow to the user, and improving the comfort of the user.

In addition, the front panel 220 is provided with a plurality of ventilation holes 221, and the front panel can slide up and down to open or cover the first air outlet. In this way, when the front panel 220 opens the first air outlet, The wall-mounted indoor unit can choose the normal air outlet mode or the multi-face air outlet mode; when the front panel 220 covers the first air outlet, since the front panel 220 is provided with a plurality of ventilation holes 221, the air outlet can be The wind speed of the flow is reduced, so as to realize the wind-free effect of the wall-mounted indoor unit.

In a preferred embodiment, referring to FIG. 6 and FIG. 7, the housing 100 may further include side panels 230 disposed on the left and right sides of the front panel 220, and the side panels 230 can slide up and down to move the first The second air outlet is at least partially opened or closed. Specifically, the two sides and the front panel 220 are integrally formed.

In order to realize that the wall-mounted indoor unit can selectively control the air outlet from any side or multiple sides, the electric control board is connected separately to independently control the two guide fans 300 .

Specifically, for the convenience of explanation, the guide fan 300 located on the left side of the air outlet channel 610 is defined as the first fan, and the second air outlet corresponding to the first fan is defined as the left air outlet; The guide fan 300 on the right side of the channel 610 is defined as the second fan, and the second air outlet corresponding to the second fan is defined as the right air outlet.

If the electric control board controls the rotation of the first fan and controls the second fan to stop, the first fan will blow a part of the air flow from the left air outlet to the room, and the remaining part of the air flow will be blown to the room from the first air outlet. If the electric control board controls the first blower to stop rotating and controls the second blower to rotate, the second blower blows a part of the air flow from the right air outlet to the room, and the rest of the air flow is blown to the room from the first air outlet. If the electric control board controls the rotation of the first fan and controls the rotation of the second fan, the first fan will blow a part of the air flow from the left air outlet to the room, and the second fan will blow the other part of the air flow from the right outlet to the room. The remaining part of the air flow is blown into the room from the first air outlet, so as to realize three sides (the front side and the left and right sides) of the air. If the electric control board controls the first fan to stop rotating, and controls the second fan to stop rotating, the air outlet airflow is only blown to the room from the first air outlet, and the conventional air outlet mode can be realized.

Further, in order to better realize that the wall-mounted indoor unit can selectively control the air outlet from any one or more sides of the indoor unit, there may be provided in the housing 100 a device that communicates with the second air outlet and the air outlet channel 610 . The air outlet 620, the air outlet 620 is movably installed with a damper, and the damper is used to open or close the air outlet 620, so that by controlling the switch state of the damper, the wall-mounted indoor unit can be selectively controlled. Wind from one or more sides.

For ease of explanation, the damper corresponding to the first fan may be defined as a first damper, and the damper corresponding to the second fan may be defined as a second damper. Wherein, when the first damper and the second damper are closed, the air outlet airflow is only blown into the room from the first air outlet to realize the normal air outlet mode; At the end of the air outlet channel 610, the flow is split from the first air outlet, the left air outlet and the right air outlet to blow out from three sides (front side and left and right sides).

In one embodiment, the damper is slidably connected with the shell body 110 , so that the damper slides to open or close the air outlet 620 . In other embodiments, the air door and the shell body 110 may also be pivotally connected, so that the air door can rotate to open or close the air outlet 620 .

Wherein, if the damper is slidably connected with the housing body 110, sliders (not shown) can be provided at both ends of the damper, and a corresponding chute (not shown) for the slider to be installed is provided on the housing body 110, and The damper is driven to slide in the chute by a driving device (not shown), so as to open or close the second air outlet 620 . This movable installation method has a relatively simple structure and is easy to manufacture. In addition, if the damper is pivotally connected to the housing body 110, a pivot shaft (not shown) may be provided at both ends of the damper, and a corresponding shaft hole (not shown) for pivoting the pivot shaft may be provided on the housing body 110. ), and the damper is driven to rotate through the driving device to open or close the air outlet 620.

It can be understood that, in order to enhance the windless air outlet effect of the wall-mounted indoor unit, the housing 100 is provided with an air outlet 620 connecting the second air outlet and the air outlet channel 610, and the air outlet 620 is installed There are air grilles (not shown). By arranging the air-passing grille, the wind speed of the air-outflow passing through the air-passing grille can be reduced, and when the airflow after the reduced wind speed passes through the first diffuser hole, the wind speed of the air-outlet airflow is further reduced, which The windless effect is better.

Please refer to Fig. 1, Fig. 2 and Fig. 4, in order to increase the windless wind effect of the wall-mounted indoor unit, a first windshield 200 can be installed in the second air outlet, and the first windshield The board 200 is provided with a plurality of first air diffuser holes through which the wall-mounted indoor unit can realize windless airflow through the first air diffuser holes. Preferably, the first windshield 200 and the side cover 140 are integrally formed.

The first windshield 200 can be fixedly installed at the second air outlet, of course, in order to change the direction of the wind from the second air outlet, the first windshield 200 can also be rotatably installed on the second air outlet. At the air outlet. It is worth mentioning that the shape of the first ventilation hole can be a round hole, a square hole, a polygonal hole, or a special-shaped hole. For example, the first air-diffusing hole is set as a round hole, which has a simple structure and is easier to manufacture; or the first air-diffusing hole is set as a petal-shaped hole, so that it can achieve the effect of no wind feeling, It can also play the role of decorating the appearance of the housing.

Further, the diameter of the first ventilation holes gradually increases from top to bottom, or/and the arrangement density of the first ventilation holes gradually increases from top to bottom. Because the distance between the first diffuser hole at the upper end of the first windshield 200 and the air inlet 121 is relatively close, and the distance between the first diffuser hole at the lower end of the first windshield 200 is far from the air inlet 121, if the first windshield The aperture of the first air diffuser hole on the wind plate 200 gradually increases from top to bottom, so that the air outlet airflow is mainly blown out from the first air diffuser hole at the lower end of the first windshield 200, which can prevent the wind from the first windshield. The airflow blown out from the first air diffuser hole at the upper end of the wind plate 200 directly flows into the casing 100 from the air inlet 121 , thereby effectively avoiding backwind. Furthermore, in order to prevent the airflow blown out from the first air diffuser hole from directly blowing to the wall, the penetrating direction of the first air diffuser hole can be set downward or/and inclined forward.

Referring to Fig. 3, the wall-mounted indoor unit further includes a second windshield 210, which is rotatably mounted on the first air outlet to open or cover the first air outlet, Wherein, the second windshield 210 is provided with a plurality of second diffuser holes.

When the wall-mounted indoor unit is working, the following two air outlet modes can be realized by opening or closing the second windshield 210:

In this mode, the second windshield 210 opens the first air outlet, and the outlet airflow is divided into multiple small airflows at the end of the air outlet channel 610, wherein the first airflow is blown out through the first air outlet; The second airflow is blown out laterally through the first diffuser hole on the first windshield 200 on one side; the third airflow is blown laterally through the first diffuser hole on the first windshield 200 on the other side blow out. That is to say, the air outlet airflow is divided into multiple airflows at the end of the air outlet channel 610 and is blown out from the lower end of the casing 100 in a diffuse manner, so that the wall-mounted indoor unit has a larger windless air outlet range. Among them, the air flow of the first air flow is obviously greater than the air flow of other air flows, and the wind speed is faster. This air outlet mode is suitable for the initial stage of cooling/heating, and can diffuse air into the room relatively quickly.

Since the wall-mounted indoor unit distributes and disperses the wind through the first windshield 200 and the second windshield 210, the airflow of the first airflow is smaller than the airflow of the conventional centralized airflow, so even the first airflow The airflow is still blown straight forward and still not focused on the user.

In this mode, the second windshield 210 covers the first air outlet, and the outlet air flow is divided into multiple small airflows at the end of the air outlet channel 610, wherein the first airflow passes through the second windshield 210. The second airflow is blown out through the first airflow hole on the first windshield 200 on one side; the third airflow is blown out through the first windshield 200 on the other side The first diffuser hole blows out sideways. This mode is suitable for the wall-mounted indoor unit to diffuse air evenly and softly into the room after the wall-mounted indoor unit has been working for a period of time. It should be noted that, in this mode, if the front panel 220 is slid downward and the first air outlet is covered, the second windshield 210 is located inside the front panel 220, so that the airflow blown from the first air outlet Passing through the second diffuser holes on the second windshield 210 and the ventilation holes 221 on the front panel 220 in sequence, the effect of no wind feeling can be further enhanced.

Here, by reasonably setting the penetrating direction of the first air diffuser hole and the second air diffuser hole, the air outlet range or air outlet direction of the wall-mounted indoor unit can be adjusted accordingly.

In the first embodiment, the penetrating direction of the first air diffuser hole is perpendicular to the surface of the first windshield 200, and the penetrating direction of the second air diffuser hole is inclined downwards to enlarge the The windless range of the wall-mounted indoor unit. Specifically, the first diffuser hole is perpendicular to the surface of the first windshield 200 and penetrates through the first windshield 200 , and the penetrating direction of the second diffuser hole is inclined downward. With this arrangement, the windless range of the wall-mounted indoor unit can be widened.

In the second embodiment, the penetrating directions of the first air diffuser hole and the second air diffuser hole are inclined forward, so that the wall-mounted indoor unit sends air forward as a whole, avoiding blown by the air flow. towards the wall. Specifically, the first air diffuser hole is penetrated from the windward side of the first windshield 200 to its air outlet surface, and the penetrating direction of the first diffuser hole is inclined forward, and the second diffuser hole penetrates The installation direction is parallel to the installation direction of the first diffuser hole, so that the outlet airflow of the wall-mounted indoor unit is blown forward as a whole, and the outlet airflow is prevented from blowing to the wall. And because the air outlet airflow passing through the first diffuser hole and the second diffuser hole is softer and the speed is lower, so the user will not feel the wind speed, which can avoid causing discomfort to the user.

In the third embodiment, the penetrating direction of the first air diffuser hole and the penetrating direction of the second air diffuser hole are set at an acute angle, so that the outlet airflow of the wall-mounted indoor unit diverges toward the indoor diffusion. Specifically, the first air diffuser hole is penetrated from the windward side of the first windshield 200 to its air outlet surface, and the penetrating direction of the first diffuser hole is inclined forward, and the second air diffuser hole The second windshield 210 is penetrated from the windward side to its wind outlet surface, and the penetrating direction of the second diffuser hole is also inclined forward, and the penetrated direction of the first diffuser hole is the same as that of the first diffuser hole. The penetrating directions of the two diffuser holes form an acute angle, so that the outlet air flows out from the first diffuser hole and the second diffuser hole respectively, and diffuses into the room in a divergent manner.

In this embodiment, in order to facilitate the introduction of part of the airflow into the first and second diffuser holes, the inner ends of the first diffuser hole and the second diffuser hole are curved from the inside to the outside. The tapered shape is arranged so that the air outlet airflow is correspondingly introduced into the first diffuser hole and the second diffuser hole.

Further, in order to facilitate the outlet air flow from the first and second diffuser holes, the outer ends of the first diffuser hole and the second diffuser hole are arc-shaped from the inside to the outside Flared setting. Specifically take the first diffuser hole as an example to illustrate the function of the arc flare: the outer end of the first diffuser hole is set as an arc flare, which reduces the air flow on the one hand. resistance, which is conducive to the rapid diffusion of the airflow passing through the first diffuser hole; on the other hand, part of the airflow diffuses along the arc-shaped flare to the wind outlet surface of the first windshield 200 to balance the airflow of the first windshield. The temperature difference between the windward side and the wind outlet side of the windshield 200 prevents condensed water from being generated on the windshield side of the first windshield 200 .

The present invention also proposes an air conditioner, which includes a wall-mounted outdoor unit and a wall-mounted indoor unit. The specific structure of the wall-mounted indoor unit refers to the above-mentioned embodiments, since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments , so at least it has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be repeated here.
