[0028] See also Figure 1 An embodiment of the utility model provides a multi-air outlet air curtain machine, including: a housing 10 and a fan 20.

[0029] See also Figure 2 A volute chamber 11, a wind curtain volute tongue 111 and a fan volute tongue 112 are provided in the outer shell 10. The wind curtain volute tongue 111 and the fan volute tongue 112 are arranged in sequence along the direction surrounding the volute chamber 11. A wind curtain air outlet 113 is formed between the wind curtain volute tongue 111 and the outer shell 10. The wind curtain air outlet 113 is located at the bottom of the outer shell 10 and faces the bottom of the outer shell 10. A fan air outlet 114 is formed between the fan volute tongue 112 and the fan volute tongue 112. The direction of the fan air outlet 114 is different from that of the wind curtain air outlet 113. The fan 20 is provided in the volute chamber 11.

[0030] The volute chamber 11 in the conventional cross-flow air curtain machine has only the wind curtain volute tongue 111, which can only form a single air outlet. Even if the air outlet is separated to achieve multiple air outlet directions, the wind flow is easily disrupted, resulting in a small wind pressure and air volume of the air outlet, and a poor wind curtain formation effect. However, the utility model uses the wind curtain volute tongue 111 and the fan volute tongue 112 to stably separate multiple wind flows, avoid reducing the wind pressure and air volume, and the wind flow is blown out from the wind curtain outlet 113 to form a wind curtain, and the wind flow is blown into the room from the fan outlet 114, thereby providing coolness for indoor personnel and promoting indoor air circulation.

[0031] See also Figure 3 In some optional embodiments, a plurality of fan volute tongues 112 are provided in the housing 10, the wind curtain volute tongue 111 and the plurality of fan volute tongues 112 are arranged in sequence along the direction surrounding the volute chamber 11, and fan air outlets 114 are formed between the wind curtain volute tongue 111 and the fan volute tongue 112 closest to the wind curtain volute tongue 111, as well as between adjacent fan volute tongues 112. The plurality of fan air outlets 114 can face different directions, so that the airflow is directed to different areas, which is convenient for customers to use. For example, in a shopping mall, different fan air outlets 114 can face the position where security personnel stand guard and the position of the customer checkout station, etc. The specific direction of the fan air outlet 114 can be designed according to actual needs, and is not limited to this example.

[0032] In some optional embodiments, the angle between the direction of the fan outlet 114 and the horizontal direction is 0°-90°. For example, the angle between the direction of the fan outlet 114 and the horizontal direction is 30°, 45°, or 60°.

[0033] The position of the air inlet 12 of the housing 10 can be designed according to actual needs. For example, in some optional embodiments, an air inlet 12 is provided on the front side of the housing 10, and the fan outlet 114 is located between the air inlet 12 and the wind curtain outlet 113.

[0034] In some optional embodiments, an air inlet grille 13 is provided on the housing 10 and is located at the air inlet 12 to achieve a preliminary filtering effect.

[0035] See also Figure 4 The specific structure of the housing 10 can be designed according to actual needs. For example, in some optional embodiments, the housing 10 includes a front cover 14, a rear cover 15 and two side covers 16. The front cover 14 and the rear cover 15 are detachably connected to each other. The two side covers 16 are arranged between the front cover 14 and the rear cover 15 and are respectively located on both sides of the front cover 14. The front cover 14, the rear cover 15 and the two side covers 16 surround and form the volute 11. The front cover 14, the rear cover 15 and the two side covers 16 can be detachably connected by screws.

[0036] In order to facilitate the installation of the housing 10, in some optional embodiments, the multi-outlet air curtain further includes a mounting bracket 17, which is detachably disposed on the rear side of the housing 10 and can be hung on a wall or other structure.

[0037] The specific structure of the fan 20 can be designed according to actual needs. For example, in some optional embodiments, a motor bracket 18 is provided in the housing 10, and the motor bracket 18 facilitates the installation of the motor 22. The fan 20 includes a wind wheel 21 and a motor 22. The wind wheel 21 is rotatably arranged in the volute 11, and the motor 22 is arranged on the motor bracket 18. The motor 22 is connected to the wind wheel 21 to drive the wind wheel 21 to rotate. In this embodiment, the fan 20 is a cross-flow fan. Of course, the fan 20 can also be a centrifugal fan.

[0038] In some optional embodiments, an air outlet grille 19 is provided on the housing 10. The air outlet grille 19 is located at the fan air outlet 114. The air outlet grille 19 can play a protective role.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
