Uniformity.

Please refer to FIG. 1 , which is a schematic structural diagram of an embodiment of an air conditioner provided with an air supply device 1 for an air conditioner according to the present invention.

As shown in Figure 1, the air conditioner of this embodiment includes a front panel 2, a rear panel 3, a left side panel, a right side panel, and a top panel and a bottom panel (not marked in the figure), which constitute the air conditioner casing. The internal air duct 4. A mixed air outlet 21 is provided on the top of the air conditioner front panel 2 , and a non-heat exchange air inlet 31 is provided at a position corresponding to the mixed air outlet 21 on the air conditioner rear panel 3 . A blower fan 6, a heat exchanger 5 and an air-conditioning air supply device 1 are arranged from bottom to top in the internal air passage 4, and the setting of the blower blower 6 makes the wind in the air-conditioning internal air passage 4 blow out from the mixed air outlet 21 on the front panel 2 .

For the structure of the air-conditioning air supply device 1 , please refer to the three-dimensional assembly structure schematic diagram in FIG. 2 , the exploded structure schematic diagram in FIG. 3 , and the rear view structural schematic diagram in FIG. 4 .

As shown in Figure 2, Figure 3 and Figure 4, the air-conditioning air supply device 1 includes three non-annular air guide bodies, which are respectively the front non-annular air guide body 11, the first middle non-annular air guide body 13 and the rear end non-annular air guide body. Air guiding body 12. Each of the three non-annular air guide bodies arranged one after the other is a single component and formed independently. Among them, the front non-annular air guide body 11 is connected in the middle and has two front and rear openings, which are respectively the mixed air outlet 111 and the air inlet 112; The air outlet 131 and the air inlet 132; the non-annular air guide body 12 at the rear end runs through the middle and has two front and rear openings, which are the air outlet 121 and the non-heat exchange air inlet 122 respectively. After the front non-annular air guide body 11, the first middle non-annular air guide body 13, and the rear end non-annular air guide body 12 are arranged in sequence, a through-flow passage that runs through all three non-annular air guide bodies is formed in the middle (in the figure not marked). Moreover, a first non-annular heat exchange air duct 14 is formed between the front non-annular air guide body 11 and the first middle non-annular air guide body 13, and the first middle non-annular air guide body 13 and the rear end non-annular air guide body A second non-annular heat exchange air duct 15 is formed between the bodies 12, and the internal air duct 4 in the air conditioner will communicate with the air conditioner through the first non-annular heat exchange air duct 14 and the second non-annular heat exchange air duct 15. The through air passages in the wind device 1 are connected.

An air distribution assembly 16 extending into the first non-annular heat exchange air channel 14 and the second non-annular heat exchange air channel 15 is arranged on the first intermediate non-annular air guide body 13 . Moreover, for the convenience of processing, the air distribution assembly 16 is preferably integrally formed with the first middle non-annular air guiding body 13 . Of course, separate molding is also possible, and then the air distribution assembly 16 is installed and fixed on the first intermediate non-annular air guide body 13 .

When the air conditioner air supply device 1 is assembled into the air conditioner, the rear non-annular air guide body 12 is fixed to the back panel 3 of the air conditioner, and the first middle non-annular air guide body 13 passes through the front non-annular air guide body 11 first. The screws are fixed, and then the front end non-annular air guide body 11 fixed with the first middle non-annular air guide body 13 is fixed on the front panel 2 of the air conditioner. After being fixed in place, the mixed air outlet 111 of the front non-annular air guide body 11 is used as the air outlet of the entire air-conditioning air supply device 1, and will be closed and assembled with the mixed air outlet 21 on the front panel 2; while the rear end non-annular air guide body 12 The non-heat-exchange air inlet 122 in the air conditioner is used as the non-heat-exchange air inlet of the entire air-conditioning air supply device 1, and will be closed and assembled with the non-heat-exchange air inlet 31 on the rear panel 3.

After the air conditioner air supply device 1 with the above structure is adopted in the air conditioner, when the air conditioner is running, the indoor air enters the interior of the air conditioner, and under the action of the fan 6, it is accelerated and blown to the heat exchanger 5 for heat exchange. The heat-exchanged air after heat exchange is blown from the internal air duct 4 to the air-conditioning air supply device 1 . Under the distribution of the air distribution assembly 16, the heat exchange air evenly enters the first non-annular heat exchange air duct 14 and the second non-annular heat exchange air duct 15 along the circumferential direction, and then enters through the heat exchange air duct Through the air passage, and then blow out from the mixed air outlet 111 on the front non-annular air guide body 11 and the mixed air outlet 21 on the front panel 2 through the through air passage. Since the speed of the heat exchange air blown from the non-annular heat exchange air duct increases, the surface pressure of the corresponding non-annular air guide body decreases and a negative pressure is formed in the through air duct, and the indoor air outside the air conditioner is used as non-heat exchange air. Under the effect of negative pressure, the non-heat exchange air inlet 31 on the rear panel 3 and the non-heat exchange air inlet 122 of the non-annular air guide body 12 at the rear end enter the through air passage, and the non-annular heat exchange air The heat exchange air blown by the duct forms a mixed air and sends it to the room together.

At a certain fan speed, the air volume test and temperature detection of the vertical air conditioner are carried out. After the above-mentioned air conditioner air supply device 1 is adopted, the non-heat exchange air introduced is about 0.65 times the heat exchange air volume, and the obtained mixed air volume is heat exchange. About 1.65 times of the air volume, compared with the air supply of the air conditioner that does not adopt the air conditioner air supply device 1 under the same situation, the air outlet of the air conditioner has increased by about 0.65 times. Moreover, if the room temperature is about 27°C, the wind blown by the air conditioner without the air conditioner air supply device 1 is heat exchange air, and its temperature is about 13°C; and after using the air conditioner air supply device 1, the mixed air sent by the air conditioner is Around 18°C, the temperature of the mixed wind is more in line with the comfort requirements of the human body temperature. Such mixed wind is relatively soft, and the user will feel more comfortable when it blows on the body, which improves the user's comfort experience effect. At the same time, the negative pressure generated by the air supply device 1 is used to inhale part of the external unheated wind to participate in the final air outlet of the air conditioner, which increases the overall air intake of the air conditioner, speeds up the flow of indoor air, and further improves the efficiency of the air conditioner. Overall uniformity of indoor air.

In this embodiment, the air-conditioning air supply device 1 is composed of a plurality of non-annular air guide bodies in the form of single parts, which is convenient for flexibly controlling the structure of each non-annular air guide body according to the air supply requirements, and conveniently processing the structure Different non-annular air guide bodies to ensure the uniformity and speed of air supply. Moreover, since each non-annular air guiding body is a single component, the assembly method of the entire air-conditioning air supply device 1 in the air conditioner can be flexibly selected, thereby improving the application range of the air-conditioning air supply device 1 and the production efficiency of the air conditioner. Moreover, by setting the air distribution assembly 16 in the heat exchange air passage, the heat exchange air entering the air supply device can be distributed in the circumferential direction by the air distribution assembly 16, thereby improving the air supply uniformity of the air supply device.

All air distribution plates are curved distribution plates with the same bending direction, and the surface of each air distribution plate is a curved curved surface, which can effectively guide the air direction and reduce the pressure loss and noise of the air flow during the distribution process, achieving low High-speed air supply under the premise of noise. The four pairs of air distribution plates are in the order of the main air distribution plates 161 and 162, the first auxiliary air distribution plates 163 and 164, the second auxiliary air distribution plates 165 and 166 and the third auxiliary air distribution plates 167 and 168, and the upper order. Left-right symmetrical distribution in the circumferential direction of the first non-annular heat exchange air passage 14 and the second non-annular heat exchange air passage 15 .

Moreover, the bending direction of each air distribution plate is opposite to the blowing direction of the heat exchange air. That is to say, if the air supply direction of the heat exchange air is from bottom to top, the bending direction of each air distribution plate will be opposite to the air supply direction, that is, the counterclockwise bending as shown in FIG. 4 .

The heat exchange air from the heat exchanger can be divided into left, middle and right by using the main air distribution plates 161 and 162 by setting the air distribution assembly 16 composed of a plurality of radially symmetrically distributed curved air distribution plates in the heat exchange air channel. Three parts, and the heat exchange air on the left and right sides can be divided again by each auxiliary air distribution plate, finally realizing the uniformity of the air inlet and outlet of the heat exchange air duct of the air conditioner air supply device 1 in the circumferential direction , the uniformity of the air supply of the air-conditioning air supply device 1 is improved.

Certainly, the air distribution assembly 16 can adopt other structures besides adopting a plurality of curved air distribution plates, as long as the heat exchanging air from the heat exchanger 5 can be evenly distributed in the circumferential direction.
