Abstract
The invention relates to an automatic lifting return air grille device of a ceiling air conditioner. The automatic lifting return air grille device comprises a return air grill which is fixedly connected with racks and motors with gears, the racks are perpendicular to the back surface of the return air grill, and the gears of the motors are meshed with the racks on the return air grill. The motors with the gears are four and respectively arranged on four angles in an indoor unit, and the gears are arranged on rotary shafts of the motors. The racks which correspond to the four gears are four and respectively arranged on four angles of the return air grill, one end of each rack is fixed at the back surface of the return air grill, and each rack is meshed with the corresponding gear. The automatic lifting return air grille fixedly connects the racks which are meshed with the gears of the motors on the return air grill and drives the racks to carry out upward and downward motion by the rotation of the gears of the motors, thereby realizing the lifting of the return air grill, leading the dusty return air grill to very easily descend from a high place and further facilitating the cleaning.
Description
Technical field
The present invention relates to air-conditioner, particularly relate to the air inlet barrier of air-conditioner.
Background technology
Air-conditioner is a kind of electrical installation of indoor temperature being regulated and remained on the required situation of user, mainly is made of cooling cycle system and air circulation system.The air conditioning effect of air-conditioner is finished jointly by cooling cycle system and air circulation system.Cooling cycle system comprises heat exchanger, compressor and throttling expansion device.Air circulation system comprises fan and fan electromotor, inlet and outlet and air filter.The cooling cycle system of air-conditioner and the operation of air circulation system are controlled by electrical apparatus control system, the refrigerating/heating operation of control air-conditioner, and carry out room temperature setting and wind speed control etc.
Cold-producing medium in the air-conditioner cooling cycle system absorbs heat and heat release in the circulation of compression → condensation → expansion → evaporation, and carry out heat exchange with room air by the fan forced flow of air circulation system, to realize room temperature lowering or intensification, for people provide fresh, comfortable indoor air environment.
Under the control of electrical apparatus control system, the refrigerant in the cylinder is compressed in the running of compressor, and the refrigerant of compressed machine compression circulates by the order of compression → condensation → expansion → evaporation in refrigeration system.The HTHP gaseous coolant that from compressor, spues, through warm high-pressure liquid refrigerant in changing into after the condenser heat release, become the low-temp low-pressure liquid refrigerants by the throttling expansion device again, then in evaporimeter with evaporimeter outside circulating air carry out heat exchange and endothermic transition is the low-temp low-pressure gaseous coolant, enter again to carry out kind of refrigeration cycle along said sequence after compressor compresses becomes the HTHP gaseous coolant.The refrigerant and the indoor flow air of circulation are carried out heat exchange in the refrigeration system, and carrying out room temperature lowering or intensification, it is temperature required that indoor temperature is remained on the user.
Air-conditioner is broadly divided into package AC plant and detachable air conditioner.Package AC plant all is contained in all parts in the casing, is installed in indoor and outdoor junction, as is installed in the window air conditioner on the room window.The heat exchanger of evaporimeter or condenser effect has been set respectively in the indoor and outdoors part.Cold-producing medium circulates in evaporimeter and condenser by the conduit that connects between the indoor and outdoors and carries out the heat exchange circulation, moves with the refrigerating state operation that realizes air-conditioner or the state that heats.
Detachable air conditioner is made up of indoor set and off-premises station, and the heat exchanger of evaporimeter or condenser effect has been set respectively in indoor set and off-premises station.Cold-producing medium circulates in evaporimeter and condenser by the conduit that connects between indoor set and the off-premises station and carries out the heat exchange circulation, moves with the refrigerating state operation that realizes air-conditioner or the state that heats.
Detachable air conditioner is broadly divided into cabinet-type, wall-hanging and ceiling-mounted air conditioner.
Ceiling-mounted air conditioner adopts ceiling embedded indoor set, and indoor units is a flat, and the air outlet of indoor set and return air inlet are arranged on the base plate of giving prominence to the ceiling below.By the room air of return air inlet suction, the heat exchanger in indoor set carries out heat exchange, flows back to indoorly again from air outlet, realizes the adjustment of room air.
Fig. 1 shows a kind of ceiling type air conditioner air conditioner indoor machine base arrangement schematic diagram of prior art.As shown in Figure 1, the outstanding base plate 1 below ceiling of indoor set is provided with return air inlet and air outlet, and return air inlet places the central authorities of base plate 1, four air outlets be arranged on return air inlet around.Air outlet is provided with wind blade 2, and the wind blade 2 of rotation is regulated air-out direction.Return air grid 3 is set on the return air inlet, and return air grid 3 prevents that foreign matter from entering indoor set from return air inlet.Return air grid 3 is passages that room air enters indoor set, is easy to be stained with dust, needs often to clean.
The indoor set of above-mentioned ceiling-mounted air conditioner shown in Figure 1, return air grid 3 on the base plate 1 is fixedly mounted on the return air inlet, and return air inlet is arranged near on the base plate 1 of ceiling, therefore, the dismounting of return air grid 3, clean very inconveniently, influence the result of use of air-conditioner.
Summary of the invention
The indoor set return air grid dismounting that exists at the ceiling-mounted air conditioner of above-mentioned prior art, clean very inconvenient problem, the present invention releases the return air grid of automatic lifting, by the fixedly connected tooth bar that meshes with motor gear on the return air grid, move up and down by the rotating band carry-over bar of motor gear and to realize the lifting of return air grid, make the return air grid that is stained with dust be easy to fall, conveniently to clean from eminence.
Ceiling-mounted air conditioner automatic lifting return air grid device involved in the present invention, comprise return air grid that is fixedly connected with tooth bar and the motor that has gear, one end of tooth bar is fixed on the back side of return air grid and vertical with the return air grid, the tooth bar engagement on the gear of motor and the return air grid.
The above-mentioned motor that has gear has four, is installed in respectively on four angles of indoor set inside, and gear is contained on the motor rotary shaft.The tooth bar of answering with four gear mesh is four, is installed on four angles of return air grid every toothed rack and a corresponding gears engaged respectively.
Motor is connected with same power switch, and under the control of a power switch, four motor start simultaneously and cut out.Gear in the motor drives rotating shaft rotates, and the tooth bar of the gear driven engagement of rotation moves up and down, and four toothed rack that move up and down simultaneously drive the lifting of return air grid.
Ceiling-mounted air conditioner automatic lifting return air grid device involved in the present invention, the rotating band carry-over bar by motor gear move up and down and realize the lifting of return air grid, and the return air grid that is stained with dust is fallen from ceiling, easily clean.
