Abstract
The utility model discloses a dew prevention device which is used for an air opening of a central air-conditioner. The utility model comprises a heating element and a humidity controller, and is characterized in that the heating element is arranged in the air opening of the air-conditioner, and the humidity controller is connected with the heating element. The humidity controller consists of connection of a humidity sensor and a switching circuit. The input end of the switching circuit is connected with the output end of the humidity sensor, and the output end of the switching circuit is connected with the heating element. The utility model effectively prevents the dewing of the air opening of the central air-conditioner, facilitates the reduction of the maintenance cost caused by the water leakage and the safety of the electrical equipment and indoor occupant.
Description
Technical field
The utility model relates to a kind of central air-conditioning anti-condensation tuyere device.
Background technology
Domestic central air-conditioning air port is merely to be made of framework at present, dewfall in use often occurs, can bring following harm like this: destroy the interior decoration environment, endanger the safety of electric equipment and bring harm to indoor occupant.
The utility model content
The purpose of this utility model just be to provide a kind of can be effectively and prevent the anti-condensation tuyere device air port dewfall, that be used for the central air-conditioning air port at low cost.
The purpose of this utility model can realize by following measure:
The utility model is included in heater element and the humidity controller of installing on the air conditioning air outlet.Humidity controller links to each other with heater element, and controller is connected and composed by humidity sensor, on-off circuit, the output of the input termination humidity sensor of on-off circuit, the output sending and receiving thermal element of on-off circuit.
Humidity controller of the present utility model is worked automatically according to the size of humidity, when humidity reaches 80% (this control point is adjustable), and heater element work, on the contrary then quit work.Working stability is reliable, and waterproof, insulation, high temperature resistant.During the humidity controller dehumidifying, the air conditioning air outlet temperature does not have significant change, can not influence the temperature in room.The utility model is discontinuity work, and energy consumption is extremely low, and is more much smaller than the annual maintenance cost of bringing because of leaking.
Description of drawings
Fig. 1 is the utility model electrical schematic diagram
The specific embodiment
As shown in the figure, heater element (1) is located to be embedded in air conditioning air outlet (2) around mode, the power circuit output end of air-conditioning temperature controller connects humidity controller (3,4), humidity controller (3,4) is connected and composed by humidity sensor (3) and on-off circuit (4), and on-off circuit (4) is connected and composed by relay (5) and resistance, electric capacity, triode, diode, the input termination humidity sensor (3) of on-off circuit (4), output links to each other with the heater element (1) of air conditioning air outlet (2).Humidity sensor (3) can be reacted to the variation of humidity, when humidity reaches 80%, the on-off circuit (4) that is made of relay (5) closes with heater element (1) from movable contact and links to each other, heater element (1) heating, the humidity of air conditioning air outlet (2) reduces, and so just the work by heater element (1) of installation in the air port (2) prevents air port (2) dewfall, when air port (2) humidity less than 80% the time, automatic and heater element (1) disconnection of relay (5), heater element (1) is not worked.
The utility model has the advantages that: effectively prevented the dewfall of central air conditioner air inlet, favourable In reducing the maintenance cost of bringing because leaking, be conducive to the safety of electric equipment and indoor occupant.
Claims (2)
1, a kind of central air-conditioning anti-condensation tuyere device comprises heater element and humidity controller, it is characterized in that heater element is contained in the air conditioning air outlet, and humidity controller links to each other with heater element.
2, a kind of central air-conditioning anti-condensation tuyere device according to claim 1, it is characterized in that humidity controller is connected and composed by humidity sensor, on-off circuit, the output of the input termination humidity sensor of on-off circuit, the output sending and receiving thermal element of on-off circuit.
