Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] Air conditioners are widely used to adjust indoor temperature. Air conditioners include indoor units and outdoor units. The indoor units are usually installed indoors and can be used to exchange heat with indoor air. The outdoor units are installed outdoors and can be used to exchange heat in the refrigerant with outdoor air.

[0003] The air conditioner indoor unit is equipped with a fresh air module, through which fresh air from outdoor is introduced into the room, realizing the function of indoor fresh air exchange and meeting the user's usage needs.

[0004] However, currently household split air conditioners have a single air outlet and cannot achieve distributed air supply at multiple locations. The indoor air circulation effect is poor, and it is difficult to achieve distributed air supply in the entire space. The indoor airflow organization is poor, and there are problems such as cold and hot air making people uncomfortable.

[0005] In addition, split air conditioners with fresh air function only consider introducing fresh air to improve indoor air quality. When the outdoor air condition is close to the target state of physical comfort, it does not consider using fresh air to bear the indoor heat and humidity load to achieve the purpose of energy-saving operation.

[0006] In addition, when introducing fresh air, it is difficult to significantly increase the fresh air volume due to the fixed position of the indoor unit and the small structural space, and the limitation of the noise of the fresh air module. Taking the 1.5p fresh air air conditioner as an example, its fresh air volume is only about 5% of the indoor unit's circulating air volume. When there is a need to cool the room air, it is difficult to adjust the indoor heat and humidity load through fresh air. Utility Model Content

[0133] In some embodiments, the fresh air inner door panel 7-17-1 and the second gear 7-2 are integrally formed, which can reduce the installation of parts and components and improve installation efficiency.

[0134] In some embodiments, the second gear 7 - 2 is configured as an incomplete gear.

[0135] In some embodiments, the second gear 7 - 2 is configured in a sector shape.

[0136] In some embodiments, in some embodiments, one side of the fresh air inner door plate 7-17-1 is set as a straight edge, and the rotation axis of the second gear 7-2 coincides with one side of the fresh air inner door plate 7-17-1.

[0137] In some embodiments, the side edges of the fresh air inner door panel 7-17-1 can be set as non-straight edges.

[0138] In some embodiments, the fresh air inner door panel 7-17-1 can rotate in the fresh air cavity. When the fresh air inner door panel 7-17-1 rotates too much, it will occupy too much space in the fresh air cavity, which is not conducive to streamlining the size of the fresh air cavity and leads to excessively high cost. Therefore, the maximum rotation angle of the fresh air inner door panel is set to less than 40°, or the maximum rotation angle of the fresh air inner door panel is set to less than 45°, or the maximum rotation angle of the fresh air inner door panel is set to less than 50°.

[0139] When the rotation angle of the fresh air inner door panel 7-17-1 is too small, the opening angle of the fresh air inner door panel 7-17-1 is too small, which is not conducive to the outdoor air flowing through the fresh air cavity and is not conducive to increasing the amount of fresh air delivered to the room. Therefore, the minimum rotation angle of the fresh air inner door panel is set to be greater than 30°, or the maximum rotation angle of the fresh air inner door panel is set to be greater than 35°, or the maximum rotation angle of the fresh air inner door panel is set to be greater than 40°.

[0140] In some embodiments, the fresh air inner door plate 7-17-1 and the second gear 7-2 are configured to be adhesively connected, and the fresh air inner door plate 7-17-1 and the second gear 7-2 are fixed by gluing.

[0141] In some embodiments, the fresh air module further includes a second filter component 5, which is disposed in the fresh air cavity. The second filter component 5 is used to filter the air flowing into the first cavity through the fresh air cavity.

[0142] In some embodiments, the second filter assembly 5 includes a second filter frame 5 - 1 , which is used to support the second filter assembly 5 , thereby improving the structural strength of the second filter assembly 5 and preventing the second filter assembly 5 from being easily deformed.

[0143] In some embodiments, the second filter assembly 5 includes a second filter 5-32-3, and the second filter 5-32-3 is arranged inside the second filter frame 5-1. Outdoor air can flow into the first cavity through the second filter 5-32-3. The second filter 5-32-3 can filter out the hair and impurities in the outdoor air again. It can be arranged that the second filter 5-32-3 adopts a high-efficiency filter, and the second filter 5-32-3 is a HEPA filter.

[0144] In some embodiments, the second filter assembly 5 includes a limiting groove 5-2, which is arranged on the second filter frame 5-1. A connecting boss is arranged in the fresh air box body 1, and the connecting boss cooperates with the second filter frame 5-1. The second filter frame 5-1 can slide along the extension direction of the limiting groove 5-2.

[0145] In some embodiments, the limiting groove 5 - 2 is extended in a straight line direction to facilitate the sliding of the second filter frame 5 - 1 .

[0146] In some embodiments, the brush 3-2 is disposed on the fresh air door panel, the brush 3-2 abuts against the first filter 3-3, and the brush 3-2 can slide against the first filter 3-3 as the door panel moves. As the door panel moves, the brush 3-2 cleans the dust and floccules on the first filter 3-3, thereby cleaning the first filter 3-3.

[0147] When the fresh air door plate opens the fresh air inlet, the fresh air inner door plate 7-17-1 rotates to connect the fresh air inlet and the fresh air outlet 8, and the outdoor air can enter the fresh air cavity through the fresh air inlet, and flow to the indoor space through the fresh air outlet 8 and the heat exchange outlet.

[0148] When the fresh air mode is turned on, the fresh air inlet drive motor 4-1 drives the first gear and the second gear 7-2 to rotate and then drives the rack part 3-4 and the fresh air door plate to move upward, and the fresh air door plate slides upward along the track 3-1 through the sliding part 3-5 thereon to realize the fresh air door plate opening the fresh air inlet. At the same time, the fresh air inner drive motor 6-1 drives the fresh air inner door plate 7-17-1 to rotate 45 degrees around the axis to open. The first filter component 2 performs a coarse filter on the fresh air, and then it is transported through the first cavity and filtered through the first filter component 2, and then enters the first cavity from the fresh air outlet 8, and then transported to the indoor space through the fan.

[0149] When the fresh air mode is turned off, the fresh air inlet drive motor 4-1 drives the first gear and the second gear 7-2 to rotate and then drives the rack portion 3-4 and the fresh air door plate to move to close the fresh air inlet. During the closing process, the brush 3-2 on the fresh air door plate brushes the first filter 3-3 from top to bottom to remove dust and flocs attached to the first filter 3-3. At the same time, the fresh air inner drive motor 6-1 drives the fresh air inner door plate 7-17-1 to rotate 45 degrees in the opposite direction around the axis to close. At this time, the fresh air module stops working.
