Background technique

With the improvement of people's living standards, air conditioners have become an important means for people to adjust the indoor temperature. Household air conditioners are usually divided into four categories: wall-mounted air conditioners, cabinet air conditioners, window air conditioners and ceiling-mounted air conditioners. The air conditioner sends the heat or cold produced by the heating or cooling of the internal system to the room through the first fan, so as to achieve the purpose of adjusting the indoor temperature.

Due to the weak health of the elderly and children, if the wind blown from the air outlet is directly blown to the human body, it will cause physical discomfort. Direct the direction of the wind blown from the air outlet from the direction perpendicular to the air outlet to the left and right sides of the air outlet, so as to avoid the wind blowing from the air outlet directly to the human body. However, when the wind deflector is used to change the air outlet direction of the air outlet, the following two problems will occur:

1. Since the existing air conditioner guides the wind bluntly to the left and right through the air deflector, it is bound to be accompanied by the loss of air volume, which affects the heat exchange efficiency of the air conditioner;

2. When the air deflector is swung to the maximum angle on the left and right sides, the air volume is also the smallest at this time, which affects the heat exchange effect at this time, that is, the heat exchange effect when the air deflector of the cabinet air conditioner swings cannot reach the direct wind. The heat transfer effect when blowing forward.

At the same time, the wind deflector cannot completely guide the wind blown from the air outlet to the left and right sides of the air outlet when swinging, so some wind will still directly blow to the human body, causing physical discomfort.

The working principle of the air conditioner indoor unit is to suck indoor air into the shell of the air conditioner indoor unit, exchange heat with the heat exchanger, and send it out to the indoor environment, thereby changing the indoor temperature.

The embodiment of the utility model provides an air conditioner indoor unit, as shown in Fig. 1 to Fig. 4, comprising a shell 1, a heat exchanger 2 and a first fan 3 are arranged in the shell 1, and a The first tuyere 11, the first fan 3 is located on one side of the heat exchanger 2 and opposite to the first tuyere 11, the top of the housing 1 is provided with a second tuyere 12, and the second tuyere 12 and the first tuyere 11 are arranged symmetrically On both sides of the heat exchanger 2 , the second air outlet 12 is also provided with a second blower 4 , which can drive air to blow in from the first air outlet 11 and blow out from the second air outlet 12 .

Compared with the prior art, the air conditioner indoor unit provided by the embodiment of the utility model, when the air is normally blown out, the first fan 3 rotates to send out the air after heat exchange with the heat exchanger 2 through the first tuyere 11, so that The room temperature has changed. If there are old people and children in the family, the second blower fan 4 can be started. At this time, the indoor air is blown into the housing 1 from the first air port 11, and is blown out from the second air port 12 after heat exchange by the heat exchanger 2. The air outlet 12 is arranged on the top of the housing 1, so the air blown out from the second air outlet 12 will flow upwards, and then diffuse along the ceiling to the room, and will not directly blow to the human body, so it will not cause discomfort to the human body. Wherein, the first air outlet 11 can be the air outlet of the existing air conditioner indoor unit, and the second air outlet 12 can be the air inlet of the existing air conditioner indoor unit, and can also be an additional air outlet for realizing the utility model.

The first fan 3 is a fan used in an ordinary air conditioner, so a cross-flow fan is often used as the first fan 3 . Since the cross-flow fan has the advantage of unlimited axial length, technicians can arbitrarily choose the length of the impeller according to different use needs, so as to meet the needs of different types of air-conditioning indoor units; at the same time, the cross-flow fan forms during rotation. The airflow of the cross-flow fan flows through the impeller and is affected by the two forces of the blades, so the airflow can reach a long distance, and it can realize long-distance air supply, which is conducive to quickly changing the indoor temperature; The wind is relatively uniform, so there will not be too much noise, and the user experience is better.

In order to increase the air outlet efficiency of the indoor unit of the air conditioner when the air is discharged from the first air outlet 11, as shown in Figures 2 and 4, the second fan 4 is an axial fan. When the user needs to change the indoor temperature quickly, the first fan 3 and the second fan 4 are started at the same time. At this time, the first fan 3 and the second fan 4 jointly drive air from the second air outlet 12 into the housing 1 of the air conditioner indoor unit. Inside, after heat exchange with the heat exchanger 2, the air is blown out from the first air outlet 11 of the air-conditioning indoor unit. At this time, the air-conditioning indoor unit is jointly discharged by the first fan 3 and the second fan 4, so the air-conditioning indoor unit The air outlet efficiency is high, and the indoor temperature can be changed rapidly. And because the air-conditioning indoor unit blows air from the first air outlet 11 at this time, this requires the direction of the air in and out of the second fan 4 to be opposite to that of the air-conditioning indoor unit when the air is discharged from the second air outlet 12, so the axial flow fan is selected. As the second fan 4, the axial flow fan can change its own rotation direction with the change of the direction of the motor, thereby changing the direction of the air in and out of the axial flow fan. Therefore, after the second fan 4 is set as the axial flow fan, the axial flow fan will When rotating in the first direction, it can realize the demand of air outlet from the second air outlet 12, avoiding the air blown from the indoor unit of the air conditioner to directly blow the human body; when the axial flow fan rotates in the second direction opposite to the first direction, it can improve The air outlet efficiency of the indoor unit makes the indoor temperature change rapidly.

In order to make the air blown into the room clean, as shown in FIG. 1 , a filter assembly 5 is provided at the second air outlet 12 . When the air-conditioning indoor unit blows air from the first air outlet 11, the indoor air enters the inside of the housing 1 of the air-conditioning indoor unit from the second air outlet 12, and since the second air outlet 12 is provided with a filter assembly 5, the air passes through the filter assembly At 5 o'clock, the impurities carried in the air are filtered by the filter assembly 5, so the air blown into the room is clean air. And when this air-conditioning indoor unit blows out from the second tuyere 12, the indoor air enters the inside of the housing 1 of the air-conditioning indoor unit from the first tuyere 11, and is blown out from the second tuyere 12 after exchanging heat with the heat exchanger 2. The second air outlet 12 is provided with a filter assembly 5, so before the air is blown out from the second air outlet 12, the impurities carried in the air will be filtered by the filter assembly 5, so the air blown into the room is clean air.

In order to achieve a better filtering effect, as shown in FIG. 1 , the filter assembly 5 includes a grille 51 and a filter screen 52 , and the grille 51 is disposed between the filter screen 52 and the second air outlet 12 . When the filter assembly 5 is arranged as a double-layer structure composed of the grid 51 and the filter net 52 , impurities in the air can be filtered more effectively. At the same time, since the grille 51 is closer to the second air outlet 12, when the air is blown from the second air outlet 12 into the housing 1 of the indoor unit of the air conditioner, it will first pass through the grille 51. The impurities with larger particles are filtered, and the air needs to pass through the filter 52 after passing through the grille 51. The filter 52 will filter the smaller particles in the air, so that the air blown into the indoor unit of the air conditioner is formed. Clean air, this part of clean air will not pollute the heat exchanger 2 when exchanging heat with the heat exchanger 2 . At the same time, since the grille 51 filters larger particles in the air, the service life of the filter screen 52 is prolonged in a disguised form. And when this air-conditioning indoor unit is blown out from the second tuyere 12, the air will also pass through the filter screen 52 and the grille 51 successively before blowing out, so the air blown into the room is clean air.

The second fan 4 will increase the load of the indoor unit of the air conditioner, therefore, the second fan 4 is detachably connected to the grill 51 . When the user does not need to let the air-conditioning indoor unit output air from the second air outlet 12, the second fan 4 can be removed from the grille 51, which reduces the load of the air-conditioning indoor unit and reduces energy consumption.

It should be noted that the second fan 4 can be detachably connected to the grille 51 through a connection structure such as buckle or bolt. The way of buckle connection is more convenient to disassemble and assemble, which is convenient for users to disassemble and assemble by themselves. The connection strength of the bolted connection is relatively high, which can ensure the long-term stable operation of the second blower fan 4 .

When the air conditioner indoor unit blows air from the second air outlet 12, the blown air is directly blown to the top of the air conditioner, flows along the indoor ceiling, and then diffuses into the indoor environment, so the indoor temperature changes slowly. To solve this problem , as shown in Fig. 3 and Fig. 4, there is a guide structure at the second air outlet 12, the air entering the indoor unit of the air conditioner is blown out from the second air outlet 12 after being heat-exchanged by the heat exchanger 2, and blows along the guide structure. To the front side of the housing 1, the air blown from the indoor unit of the air conditioner is directly diffused in the indoor environment, and the speed of the indoor temperature change is accelerated.

Specifically, as shown in FIG. 4 , the flow guide structure is a flow guide cover 6 covering the second tuyere 12, and the cover body of the flow guide cover 6 facing the front side of the housing 1 is provided with a flow guide opening 61, from which The air blown out by the second tuyere 12 flows along the inner wall of the air guide cover 6 to the air guide port 61 on the cover body of the air guide cover 6 facing the front side of the housing 1, and then blows out from the air guide port 61, and is directly diffused on the air guide cover 6. In the indoor environment, the indoor temperature changes rapidly.

In order to prevent impurities in the indoor air from contaminating the first fan 3 and the heat exchanger 2 , a filter assembly is also provided at the first tuyere 11 . When the air-conditioning indoor unit blows air from the second air outlet 12, the indoor air enters the inside of the housing 1 of the air-conditioning indoor unit from the first air outlet 11, exchanges heat with the heat exchanger 2, and blows out from the second air outlet 12. A filter assembly is provided at a tuyere 11, so before the air is blown into the casing 1 of the air conditioner indoor unit, the impurities carried in the air will be filtered by the filter assembly, so that the air is blown into the casing 1 of the air conditioner indoor unit The air is clean air, and this part of the clean air will not pollute the first fan 3 and the heat exchanger 2 after being in contact with the first fan 3 and the heat exchanger 2.

It should be noted that, when the air conditioner indoor unit blows air from the first air outlet 11, the first fan 3 or the axial flow fan can be turned on separately. When the first blower 3 is turned on alone, the indoor air is blown into the housing 1 of the indoor unit of the air conditioner from the second air outlet 12, and after exchanging heat by the heat exchanger 2, it is blown out from the first air outlet 11, thereby changing the indoor temperature. When the axial flow fan is turned on alone, the axial flow fan rotates in the second direction, driving the air from the second air outlet 12 into the interior of the housing 1 of the air conditioner indoor unit to exchange heat with the heat exchanger 2, and then from the first air outlet 11 Blow out to make changes to the room temperature.

Other configurations of the air-conditioning indoor unit in the embodiment of the present invention are well known to those skilled in the art, and will not be described in detail here.

The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Anyone familiar with the technical field can easily think of changes or changes within the technical scope disclosed by the utility model Replacement should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
