In addition, in order to increase the dehumidification effect of the bathroom, a mechanical refrigeration apparatus is installed in the bathroom separately from the ventilator to condense moisture by the condenser cooled according to the mechanical operation of the refrigerator, and most of the condensate is drained to the drain. Water suspended in air was removed by a fan.

The dehumidification means of the conventional bathroom is provided with a ventilator for ventilating the air, and a refrigeration apparatus for condensing moisture in the room, the condensed water condensed by the refrigeration apparatus is drained to the drain and the air containing moisture is dehumidified by the ventilator. In addition, the space and installation efficiency of the installation of the ventilation fan and the refrigeration equipment are inconvenient, and the installation cost is high.In addition, the operation of the refrigeration apparatus causes the noise of the mechanical movement of the compressor to be unpleasant, and the electric energy cost is increased and managed. There was a problem of uncomfortable handling.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ventilator in which a dehumidification mechanism that combines a thermoelectric module, a condenser, a radiator, and a heater pipe is combined, and has a dehumidification mechanism that can serve as a ventilation function and a dehumidification function.

Another object of the present invention is that the dehumidification mechanism is coupled to the ventilator is easy to install, the dehumidification mechanism has no operation noise, and the radiator of the dehumidification apparatus is cooled by the simultaneous exhaust air condensing moisture by the condenser at the inlet side of the ventilator and discharged to the discharge pipe. The purpose of the present invention is to provide a ventilator in which a dehumidification mechanism can be efficiently dehumidified by maintaining a good dehumidification function without reaching a saturation temperature.

The present invention, in order to achieve the above object, a rotating fan is installed in the housing mounted inside the gas and the circulation pipe and the discharge pipe is formed on both sides of the gas to suck the indoor air to the inlet of the housing through the cover by the rotating fan In the ventilator is discharged to the outside or ventilated.

A plurality of thermoelectric modules made of a semiconductor of the dehumidifier are mounted on one side of the gas of the fan and connected to a cold plate of the thermoelectric module by a heat pipe to condense moisture by cooling. A condenser equipped with condensing fins is mounted on the air inlet side of the housing inside the cover under the gas, and is connected to a hot plate of the thermoelectric module to heat the condenser to evaporate condensed water. A radiator having a plurality of radiating fins is configured to be mounted on the exhaust pipe side of the fan.

 The thermoelectric module was invented by Peltier in 1834 and is also known as "Peltier" as the inventor's name. As a special NP type semiconductor, when a predetermined operating current is applied to both electrodes, one pole has a low temperature cold plate. On the other hand, the opposite pole is a known semiconductor device which is used as a refrigeration or freezing mechanism because of its characteristic of being a hot electrode plate having a high temperature. The operating voltage is 12 ~ 20V DC and the current varies depending on the capacity, but it is generally about 30A, and has the thermoelectric characteristics of -50 ℃ on the cold plate side and + 70 ℃ on the hot plate side.

For example, the ventilator of the present invention can be installed in a bathroom to operate a rotating fan inside the housing to suck the indoor air and circulate the circulating pipes to vent the outside air and exhaust the sucked air to the exhaust pipe. It may be.

On the other hand, when dehumidifying by the dehumidifier, when the humidity of the bathroom is 70% or more, the circulating power damper of the fan is closed and the discharge damper is opened according to the detection signal detected by the humidity sensor installed in the ventilator. The module is supplied with a predetermined operating power source. When a DC 20V operating power is applied to the thermoelectronic module, cold air is transferred to the condenser through a heat pipe connected to the cold electrode plate side having a lowered temperature according to the operation of the thermoelectronic module. The heat pipe itself has a function of heat conduction. The cooling temperature is variable, but is set at about 2 ~ 5 ℃. The water in the bathroom is condensed by the endothermic application of multiple cooling fins. The condensed condensed water is drawn into the inlet of the housing and discharged to the discharge pipe by driving the fan together with the air. At this time, heat is transferred through the heat pipe connected to the heated hot plate of the thermoelectric module, and heat is emitted from the radiating fin of the radiator by about 30 to 40 ° C. The radiator is easily discharged by air without adding a separate cooling system. Because of the cooling, the hot electrode plate side of the thermo-electronic module does not reach the saturation temperature, and the operation of the thermo-electronic module continues well and the water of the bathroom is removed. Depending on the exhaust volume of the fan, the dehumidification operation is completed in about 30 minutes.

When the humidity inside the bathroom reaches the normal value by the humidity sensor, the operating power of the fan and the thermoelectric module is automatically shut off.

According to the present invention, the structure of the dehumidification mechanism is simple and can be coupled to the effective space of the ventilator, there is no operation noise, and the automatic control of the dehumidification mechanism can be easily dehumidified in the bathroom.

In the present invention, since the dehumidification mechanism consisting of a thermoelectric module, a condenser, a radiator, and a heater pipe is combined with a fan, the structure is simple and easy to install, and also has a ventilation function and a dehumidification function. Can be.

The dehumidification mechanism has no operation noise because it adopts a thermo-electronic module as the dehumidification mechanism, and the condenser of the dehumidification mechanism is installed on the inlet side of the fan to condense moisture in the intake air and discharge it to the discharge pipe. The radiator is cooled by the exhaust air, and the dehumidification function is maintained well without reaching the saturation temperature, so that ventilation and dehumidification can be efficiently performed.

As shown in FIGS. 1 and 2, a rotating fan 3 is installed in a housing 2 mounted inside the body 1, and a circulation tube 4 is formed on one side of the body 1. A discharge pipe 5 is formed on the other side of the base 1, and a central inner side of the cover 6 is formed of an outer plate 6a mounted on the bottom of the base 1 and an inner plate 6b having a ventilation gap 6c. In the fan (F) in which the air inlet (2h) is formed in the housing (2) to vent or exhaust the indoor air.

On one side of the base 1, a thermoelectric module 7 made of a semiconductor of the dehumidifier C is mounted. The thermoelectronic module is a rectangular solid, and can be easily installed in the effective space inside the gas of the fan. 3 and 4, indoor air is sucked into the condenser 8 having a plurality of cooling fins 8f formed on the heat pipe 8p connected to the cold electrode plate 7c side of the thermoelectric module 7. The cold electrode plate 7c of the thermoelectric module 7 is mounted together with a shutter S which opens and closes the air intake port 2h between the inside of the cover 6, which is a passage, and the air intake port 2h side of the housing 2. Moisture contained in the air of the room is condensed to the cooling fin (8f) cooled by the endothermic action of. The exhaust pipe 5 of the fan so that the heat radiator 9 having a plurality of heat dissipation fins 9f formed on the heat pipe 9p connected to the hot electrode plate 7h of the thermoelectric module 7 can be cooled in surface contact with the discharge air. Mounted on the side so that the heat of the hot electrode plate 9h of the thermoelectric module 7 is transferred to the heat pipe 9p so that it can be cooled by the simultaneous discharge air to radiate heat from the radiating fin 9f of the radiator 9. Combination to construct.

  For example, when the fan (F) of the present invention is installed on the ceiling of a bathroom, and is intended to be used for the purpose of venting, when a vent switch (not shown) is connected, operating power is supplied from an electronic controller (not shown) provided in the ventilator. The unshown power damper on the discharge pipe 5 side is closed, the unshown damper on the circulation pipe 4 side is opened, and the driving power is supplied to the drive motor 3m of the fan F so that the rotating fan 3 Driven. The air sucked into the inlet port 2h of the housing 2 through the ventilation gap 6c between the outer plate 6a and the inner plate 9b of the cover 6 as the rotary fan 3 is driven is circulated. The outside air is discharged to the outside and the outside air is sucked through the space of the bathroom back to the intake port (2h) of the housing (2) of the fan (F) to be repeatedly vented. Therefore, the bathroom is kept dry. When the ventilation of the bathroom ends, the fan is stopped.

After using or using the bathroom, when the bathroom has a humidity of 70% or more, the circulation pipe of the fan (F) by the operating power supplied from the electronic controller in accordance with the detection signal of the humidity sensor (not shown) installed in the fan (F) ( 4) The side power damper is closed and the discharge pipe 5 side damper is opened, and the rotary fan 3 of the fan F is driven. On the other hand, predetermined operating power sources DC 12V, 20A, are supplied to the thermoelectric module 7 of the dehumidifying mechanism C. When the operating power is applied to the thermoelectronic module 7, the heat pipe 8p connected to the cold electrode plate side 8p whose temperature is lowered by the endothermic action is also lowered according to the operation of the thermoelectric module 7 and the heat pipe 8p. The condenser 8, in which the cooling fins 8f are formed, is also cooled. The heat pipe itself has a function of heat conduction. Cooling temperature is variable, but about 2 ~ 5 ℃. The water in the bathroom is condensed by the endothermic application of the plurality of cooling fins 8f. The water molecules condensed on the cooling fins 8f are separated from the cooling fins by the flow energy of the air, are sucked together with the air to the inlet 2h of the housing 2, and discharged to the open discharge pipe 5. At this time, heat is transferred through the heat pipe 9p connected to the heated hot plate 9p of the thermoelectric module 7, and heat of about 30 ° C. to 40 ° C. is released from the heat radiating fin 9f of the radiator 9. Since the radiator 9 is located at the discharge pipe 5 side of the fan, the discharged air discharged to the discharge pipe 5 between the plurality of heat radiating fins 9f moves to the surface contact and quickly discharges the radiated heat to the outside. The radiator 9 is kept in good heat dissipation by the exhaust air. Therefore, the temperature of the column electrode 7h side of the thermoelectronic module 7 is controlled so as not to reach the saturation temperature, so that the operation of the thermoelectronic module 7 continues well. In this way, the operation of the dehumidification mechanism of the ventilator is maintained smoothly, the dehumidification is good. When the humidity inside the bathroom reaches the normal value by the humidity sensor, the operating power of the fan and the thermoelectric module is automatically cut off.

    In the practice of the present invention, the condenser of the dehumidification mechanism is located on the air inlet side of the fan to easily move the moisture condensed on the cooling fins of the condenser by the moving energy to the suctioned air together with the air. It is possible to maintain the cooling by the exhaust air radiator heat dissipation heat to position the condition that the operation of the thermoelectric module of the dehumidification mechanism is maintained satisfactorily can be dehumidified efficiently.

In addition, the heat exchange operation of the thermo-electronic module has no mechanical operation or noise, easy to control the electric field, and can be used more conveniently than the conventional fan because it is simple to use and manage.
