Further, the comfort of the wall-mounted indoor unit is improved.

Please refer to Fig. 1 to Fig. 3, in the first embodiment of the wall-mounted indoor unit of the present invention, the wall-mounted indoor unit includes a housing 100, two windshields 10, a pushing mechanism (not shown) and two turning mechanisms ( not shown); wherein, the housing 100 has an air outlet; the windshield 10 is arranged up and down at the air outlet; the pushing mechanism is located in the housing 100 and connects the two windshields 10 to push The two windshields 10 move away from or close to the air outlet; the two turning mechanisms are installed on the pushing mechanism, and are connected to the two windshields 10 correspondingly in order to drive the two windshields 10 to turn over.

Specifically, the top of the housing 100 has an air inlet 111, and the inside of the housing 100 is provided with a heat exchanger 200 and a wind wheel 300 in sequence on the lower side of the air inlet 111; the housing 100 includes a panel 110, and the air outlet is located at the lower end of the panel 110. When the indoor unit of the air conditioner is working, the air in the room enters from the air inlet 111 , and after being exchanged by the heat exchanger 200 , is driven by the wind wheel 300 to flow out to the air outlet.

The windshields 10 are arranged up and down at the air outlet, and through the pushing mechanism, push the two windshields 10 to move away from the air outlet to open the air outlet, or push the two windshields 10 to Move close to the air outlet to close the air outlet.

The two overturning mechanisms are installed on the pushing mechanism, and are correspondingly connected with the two windshields 10 in turn, so that after the pushing mechanism pushes the two windshields 10 away from the air outlet, the two overturning mechanisms drive the two windshields respectively. The wind panels 10 are flipped over to change the deflection angles of the two wind deflectors 10 , so that the two wind deflectors 10 can guide the air outlet airflow to different directions, thereby realizing switching the flow direction of the air outlet airflow from the air outlet.

It should be noted that the reciprocating movement of the pushing mechanism to push the two windshields 10 away from or close to the air outlet is performed outside the air outlet, so that the windshield 10 can obtain a larger The overturning space prevents the windshield 10 from being interfered by the periphery of the air outlet during the overturning process.

When the wall-mounted indoor unit is working, use the controller of the wall-mounted indoor unit to control the pushing mechanism to push the windshield 10 away from the air outlet, and then control the two turning mechanisms to drive the two windshields 10 respectively.

The lower windshield 10 is defined as the second windshield 10B:

Please refer to FIG. 3 , in this mode, the first wind deflector 10A and the second wind deflector 10B are turned over so that their windward surfaces are opposite to each other. The outlet airflow of the wall-mounted indoor unit is not divided, and only one airflow is formed to be blown directly from the air outlet to realize rapid cooling. This mode is suitable for the initial cooling of the wall-mounted indoor unit to quickly cool down the room.

Please refer to FIG. 4 , in this mode, the first windshield 10A is turned over to the upper edge of the windward surface facing the air outlet, and the second windshield 10 is turned so that the windward side is facing the lower edge of the air outlet. edge. The outlet airflow of the wall-mounted indoor unit is divided into two airflows by the two windshields 10, wherein the first airflow is blown upwards along the windward side of the first windshield 10A, and then naturally settles down in the form of spraying. , during this process, the wind speed decreases and will not directly blow to the user; the second airflow is inclined along the windward side of the second windshield 10B and blows downward to the wall of the wall-mounted indoor unit, so the The second air flow will not blow towards the user either. And in this mode, a small gap is formed between the leeward surface of the first windshield 10A and the leeward side of the second windshield 10B, and a small amount of airflow passes through the gap and blows the air. To the leeward side of the first windshield 10A and the second windshield 10B, thereby effectively balancing the temperature difference between the two surfaces of the first windshield 10A and the second windshield 10B, thereby avoiding Condensed water is generated on the leeward side of the second windshield 10B. That is to say, in this mode, the wall-mounted indoor unit realizes two outlets of air, and neither of the two outlets blows directly to the user, so that the wind is blown without wind feeling and at the same time, the generation of condensed water is effectively avoided.

The outer side of the air outlet reciprocates away from or close to the air outlet, so that the windshield 10 can obtain a larger turning space, and after the pushing mechanism pushes the two windshields 10 away from the air outlet, through The two overturning mechanisms installed on the pushing mechanism respectively drive the two windshields 10 to turn over to change the deflection angles of the two windshields 10, so that the outlet airflow can be guided to different directions through the two windshields 10 , so as to switch the flow direction of the airflow from the air outlet.

Since the windshield 10 is flipped on the outside of the air outlet to guide the wind, the airflow blown out through the air outlet will blow along the windshield 10 to a farther position, and finally spread to the indoor environment In this way, cooling/heating can be performed on an area farther away from the wall-mounted indoor unit. However, in the prior art, the conventional windshield 10 only swings in the air outlet to change the flow direction of the air outlet. cooling/heating in the area of the above-mentioned wall-mounted indoor unit. It can be seen that the windshield 10 of the wall-mounted indoor unit of the present invention also has the effect of extending the air supply distance of the air flow.

Please refer to FIG. 2 to FIG. 4 , there are various arrangements for the structure of the pushing mechanism, and the pushing mechanism can push the two windshields 10 to move synchronously, or push the two windshields 10 to move independently.

Push the wind deflector 10 outward or inward to move.

The manner in which the push rod is slidably installed in the housing 100 may be that a collar or a slideway is provided in the housing 100, and the inner end of the push rod slides with the housing 100 through the collar or slideway. Connection, in order to prevent the push rod from slipping off from the collar, the inner end of the push rod and the collar are provided with a matching anti-off structure, such as an anti-off buckle or an anti-off self-locking shrapnel.

In order to reduce the energy consumption of the first motor, the driving device can also be provided with a return spring at the inner end of the push rod, one end of the return spring is connected with the inner end of the push rod, and the return spring The other end of the other end is connected with the housing 100, so as to utilize the elasticity of the return spring to assist the reciprocating movement of the push rod, thereby reducing the energy consumption of the first motor.

In other embodiments, if the pushing device drives the two windshields 10 to move synchronously, the pushing device includes a first motor, a gear connected to the first motor, and a push rod bracket. The push rod bracket is slidably installed inside and outside the housing 100, the push rod bracket has a first push rod connected with the first windshield 10A, a second pushrod connected with the second windshield 10B, And a connecting rod connecting the first push rod and the second push rod. The first push rod or the second push rod is provided with a rack meshed with the gear to drive the push rod bracket to slide inward or outward through the first motor to drive the two windshields 10 reciprocating outside the air outlet.

Please refer to FIG. 3 and FIG. 4 , the structure of the turning mechanism can be arranged in various ways, which are not limited here.

In this embodiment, the two overturning mechanisms are respectively arranged on two groups of the driving groups, each of the overturning mechanisms includes a second motor installed on the outer end of the push rod of the driving group, and the windshield 10 Lugs are provided on the windward side, and the drive shaft of the second motor is connected to the lugs to drive the windshield 10 to turn up and down.

Specifically, the outer end of each push rod is arranged in the motor box, the second motor of the turning mechanism is installed in the motor box, and the drive shaft of the second motor protrudes from the motor box to be in contact with the motor box. The lugs are connected, and the wind deflector 10 is driven to rotate by the second motor.

In other embodiments, the turning mechanism may include a second motor and a crank mounted on the outer end of the push rod, one end of the crank is connected to the drive shaft of the second motor, and the other end of the crank is connected to the stopper. The windward side of the windshield 10 is connected, and the second motor is used to drive the crank to swing to drive the windshield 10 to turn up and down.

Please refer to FIG. 4 , in this embodiment, the windshield 10 can be arranged in a flat shape or in an arc shape, and there is no specific limitation. However, considering the flat windshield 10, its air guide effect is relatively poor, and when the outflow airflow with a relatively high wind speed directly hits the flat windshield 10, relatively large noises are likely to be generated. .

Therefore, preferably, the windward surface of each windshield 10 is arranged in an outwardly concave arc shape from its upper edge to its lower edge. Such setting makes the windward surface of the windshield 10 form an arc-shaped guide surface, and when the outlet airflow with a relatively high wind speed blows to the windward surface of the windshield 10, it will be blown smoothly along the arc-shaped guide surface, thereby enhancing its Diversion effect, and not easy to generate noise.

Please refer to Fig. 4, in this embodiment, in order to facilitate the windshield 10 to dredge the outlet air flow, the windward surface of the windshield 10 is provided with a plurality of guide grooves extending along the width direction of the windshield 10 (not shown). ), and a plurality of said guide grooves are arranged at intervals along the length direction of the wind deflector 10 .

Specifically, the length direction of the windshield 10 is consistent with the length direction of the air outlet, and the guide groove can be arranged in a U-shape or a V-shape opening to the air outlet side. A plurality of guide grooves on the windshield 10, on the one hand, can comb the outlet airflow into a plurality of smaller airflows when the outlet airflow blows to the windshield 10, so that the outlet airflow flows more gently toward the windshield 10. to avoid dizziness or cold and other uncomfortable symptoms caused by the strong wind feeling; Enlarging the contact area between the windshield 10 and the air outlet airflow effectively increases the wind resistance of the airflow flow, thereby helping to reduce the wind speed of the air outlet airflow and realize windless airflow.

Preferably, the guide groove has two connected guide surfaces, and the angle formed between the two guide surfaces ranges from 30° to 120°, such as 45°, 65°, 85° or 115°. Can. If the α is less than 30°, the angle formed between the two connected diversion surfaces of the diversion groove 120 is too small, and the resistance of the diversion groove 120 to the outlet air flow is relatively large, and the outlet air flow is not easy to self-direct. Groove 120 passes; If described α is greater than 120 °, then the included angle formed between the two connected diversion surfaces of diversion groove 120 is too large, and diversion groove 120 is less to the resistance of outlet air flow, and outlet air flow Passing through the guide groove 120 quickly, the combing effect of the guide groove 120 on the outlet airflow is not obvious. Therefore, the range of the included angle formed between two connected diversion surfaces of the diversion groove 120 is limited to 30°˜120°.

Please refer to Figure 3. In this embodiment, in order to enhance the dredging effect of the flow guide groove on the outlet air flow, the depth of the flow guide groove is gradually reduced in the flow direction of the flow guide groove. .

This setting method is to take into account that the wind speed of the air outlet airflow before entering the diversion groove is relatively large. If the depth of the diversion groove is small, the outlet air flow is easy to rush out of the diversion groove, and it is not easy to gather into the diversion groove. Blow out from the diversion tank. Therefore, by gradually reducing the depth of the flow guide groove in the flow direction of the flow guide groove, the groove cavity at the front end of the flow guide groove can be made larger, on the one hand The contact area between the guide groove and the air outlet air flow is relatively large, which is beneficial to increase the wind resistance to reduce the wind speed of the air outlet air flow. flow effect; and the groove cavity at the rear end of the diversion groove in the diversion direction is smaller, the contact area between the diversion groove and the outlet air flow is smaller, and the wind resistance is smaller, which is conducive to the outlet air flow from the The rear end of the diversion tank is exported.

Considering that, in different modes, the flow direction of the flow guide grooves on the two wind deflectors 10 is different, so the design should be selected according to the air outlet mode mainly used by the user.

Please refer to Figure 4. If the user uses the windless air outlet mode 1 of the above-mentioned wall-mounted indoor unit more often, and the other air outlet modes are less used, then the air guide of the two windshields 10 in the first air outlet mode direction prevails. Wherein, the depth of the diversion groove on the first windshield 10A is gradually reduced from the lower edge of the first windshield 10A to its upper edge, so as to strengthen the upward dredging of the first windshield 10A to the airflow. The effect of flow; the depth of the diversion groove on the second windshield 10B is gradually reduced from the upper edge of the second windshield 10B to its lower edge, so as to strengthen the second windshield 10B to the air flow upward dredging effect. Therefore, the air blowing effect of the windless mode can be enhanced.

Please refer to FIG. 5 , if the user is more accustomed to the windless air outlet mode 2 of the above-mentioned wall-mounted indoor unit, then the air guide direction of the two windshields 10 in the air outlet mode 2 shall prevail. As shown in Figure 5, the depths of the guide grooves on the first windshield 10A and the second windshield 10B are gradually reduced from bottom to top, so that the first windshield 10A and the second windshield can be strengthened. The wind plate 10B has the effect of dredging the air flow upward at the same time.

Please refer to FIG. 6 , if the user is more accustomed to the air outlet mode 3 of the above-mentioned wall-mounted indoor unit, the flow direction of the two windshields 10 in the air outlet mode 3 shall prevail. That is to say, the depths of the guide grooves on the first windshield 10A and the second windshield 10B are set to gradually decrease from bottom to top, so as to strengthen the first windshield 10A and the second windshield 10B to let out the air at the same time. The effect of flow downward dredging.

Please refer to Figures 4 to 6. In this embodiment, in order to effectively guide the air outlet airflow driven by the wind wheel 300 to the air outlet, a volute 400 is provided in the housing 100, and the volute 400 has a The air outlet duct 410 connected to the air outlet, the volute 400 is rotatably installed in the air outlet duct 410 with the deflector 20 .

The rotation installation method of the deflector 20 can be pivoted or hinged. By adjusting the angle at which the deflector 20 turns, the flow direction of the airflow in the air outlet channel can be adjusted to be biased towards the windward side of the two windshields 10, and then The amount of air blown upward or downward by the outlet airflow can be controlled.

Considering that the temperature of the air outlet is relatively low, when the air outlet is blown out from the air outlet, the leeward sides of the two windshields 10 will generate condensed water, so preferably, the windward side of the windshields 10 is provided with an insulating layer. Specifically, the windward surfaces of the two windshields 10 are all provided with the insulation layer, and the insulation layer can be thermal insulation cotton or heat insulation foam, so as to prevent the airflow from passing through the air outlet, the windshield 10 Condensation occurs on the leeward side of the
