The invention discloses a defrosting control device, an air conditioner and a defrosting control method of the air conditioner. The defrosting control device comprises an air bag device which is usedfor forming an air bag layer when the to-be-controlled air conditioner enters in a defrosting mode to isolate an outdoor heat exchanger of the to-be-controlled air conditioner from external flowing air of the outdoor heat exchanger. According to the scheme, the defects that in the prior art, the defrosting heat loss is large, the defrosting effect is poor, and the user experience is poor can be overcome, and the beneficial effects that the defrosting heat loss is few, the defrosting effect is good, and the user experience is good are achieved.

The invention relates to an air-conditioner with an air refreshing function. The air-conditioner comprises a base disc, a top cover, a back plate, a left lateral plate, a right lateral plate, an air outlet frame, an upper panel body and a lower panel body which form a machine casing together, a heat exchanger, a volute, a motor and the like which are arranged in the machine casing, air inlets arranged on the left lateral plate and the right lateral plate and a filtering screen assembly or a baffle rotatably installed at the position of the air inlets through a rotating shaft. The filtering screen assembly or the baffle is controlled by the motor to rotate with the rotating shaft as the center to open / close the air inlets. When smoke and dust are required to be removed, the motor controls the filtering screen assembly or the baffle to approach the air inlets, air needs to pass through a filtering screen to enter a volute air channel system to clear smoke and dust in the air. When smoke and dust removing is not required, the motor controls the filtering screen assembly or the baffle to be far away from the air inlets, and the air can directly enter the volute air channel system from the air inlets without affecting air inlet quantity of the air-conditioner. Therefore, working efficiency of the air-conditioner is improved.

The invention relates to a desktop air conditioner. Specifically, the desktop air conditioner is provided with a body and a maintenance cover board; the body comprises a body housing, the surrounding wall of the body housing is provided with a maintenance opening and a baffle formed in the maintenance opening, and the baffle is provided with an air inlet; the maintenance cover board is so arranged as to operably open and close the maintenance opening, the maintenance cover board is provided with a first air inlet part, and an airflow passage is formed between the maintenance cover board and the baffle to receive airflow coming from the first air inlet part and supply the airflow into the body housing via the air inlet of the baffle. Since the desktop air conditioner is provided with the maintenance opening and the maintenance cover board, parts which often need to be taken out of or put into the desktop air conditioner can be conveniently taken out and put in. Moreover, since the airflow passage is formed between the maintenance cover board and the baffle, air on the first air inlet part can get into the body housing as rapidly and sufficiently as possible.

The invention discloses a dustproof case. The dustproof case comprises a case body, wherein a dustproof box, a cover plate and a screening plate are arranged on the side face of the case body; the dustproof box comprises a box body, the box body is of a hollow cube structure protruding out of the side wall of the case body, the lower end of the box body is provided with an opening which is an airguide port, an air inlet is arranged at the inner side of the box body and located at the position, close to the top end of the box body, on the side wall of the case body, and a strip-like through slot is arranged at the position, close to the side wall of the case body, of the top end of the box body; the cover plate is of a flat plate structure with one side face provided with a baffle, the part, located at one side of the baffle, of the flat plate is a ventilation part, the part, located at the other side of the baffle, of the flat plate is an air resisting part, and both the ventilation part and the air resisting part can be inserted through the strip-like through slot at the top end of the box body; and the oblique screening plate is movably connected to the box body. The dustproof case has a good dustproof effect.

The invention relates to an air conditioner with air refreshing function, comprising: a chassis, a top cover, a back plate, a left side plate, a right side plate, an air exhaust frame, an upper plate body and a lower plate body which jointly form a casing; air conditioner components arranged inside the casing, such as a heat exchanger, a volute casing, an electric motor and the like; air inlets arranged on the left side plate and the right side plate; and filter screen modules or baffle plates which can be rotatably mounted at the air inlets via rotating shafts, wherein the filter screen modules or the baffle plates are controlled by the electric motor so that the rotating shafts implement central rotation to open / close the air inlets. When smoke and dust need to be removed, the electric motor control the filter screen modules or the baffle plates to get close to the air inlets, the air can enter a volute casing air channel system only after passing through the filter screen so that smoke and dust in the air can be cleared away; when smoke and dust do not need to be removed, the electric motor control the filter screen modules or the baffle plates to get away from the air inlets, the air can enter the volute casing air channel system directly from the air inlets without having an effect on the air intake of the air conditioner, thereby enhancing the working efficiency of the air conditioner.

The invention discloses a stacking door device for a cooling tower. The stacking door device includes: guide rail uprights; reels, arranged on the top of the pair of double guide rail uprights, and are controlled and driven to rotate; wind curtains; a plurality of wind-resistant rods, the plurality of wind-resistant rods are arranged horizontally on the wind curtain; and a traction member whose upper end is wound by the reel and whose lower end is fixed to one of the lower wind-resistant rods, wherein the traction member passes through the plurality of wind-resistant At least a part of the rod is a part on the wind-resistant rod, so as to adjust the position of the lower end of the wind control curtain under the winding of the reel. According to the stacking door device of the present invention, not only can satisfy the overall wind resistance performance of the air curtain, but also can be stacked neatly, with small stacking volume, simple structure and low cost. In addition, the stacking door device does not affect the air intake of the cooling tower in summer, thereby meeting the cold protection and energy saving requirements of the cooling tower with the stacking curtain.

The invention provides a wall-mounted air conditioner indoor machine adopting an air purification device. The wall-mounted air conditioner indoor machine comprises an enclosure, a heat exchanger in the enclosure, an air inlet at the top of the enclosure and an air purification module at the air inlet, and is characterized in that the air inlet of the enclosure at the heat exchanger is provided with a guide rail; the air purification module is in a flaky flexible or foldaway shutter shape; and the air purification module moves along the guide rail, can move to a position where the air purification module shields the air inlet of an air conditioner and can move to a position where the air purification module is away from the air inlet of the air conditioner and integrally moves into the enclosure, so that not only can the air purification effect of the air purification device be exerted, but also the air purification device does not influence the inlet air quantity of the air conditioner when only the air conditioning function is utilized. The wall-mounted air conditioner indoor machine is simple and compact in structure and convenient in operation.
