In general, mattresses are beddings used for blankets, duvets or beds when sleeping on the floor or on the floor. In addition, the mattress serves as a cushioning material for hard floors and also serves as an insulator that does not affect the temperature of the floor surface.

Insulating the temperature of the floor alone is not enough to create a comfortable sleeping environment, and many efforts have been made to add cooling or heating functions to the mattress.

As one of these efforts, Utility Model Registration No. 20-0378388 has a temperature sensing sensor and a forward / backward switching circuit in addition to a circulation pipe filled with a heat medium inside the mattress and a circulation pump connected between the circulation pipe and the thermoelectric module. The mattress is described. When the mattress temperature is higher than the set temperature, the mattress sends electricity to the thermoelectric module in the cooling direction when the temperature of the mattress is higher than the set temperature, and when the temperature of the mattress is lower than the set temperature, the mattress is heated in the heating direction. By letting go, you will maintain a pleasant sleeping environment.

When a current is connected by connecting different materials, the thermoelectric module using the Peltier effect, in which the temperature drops on one side and the temperature increases on the other side, can heat / cool the heating medium according to the direction of the current. have. Such thermoelectric modules have recently used semiconductors such as bismuth (Bi) and tellurium (Te), and include a reaction surface opposite to the action surface for heating / cooling the heat medium. These mattresses are mainly used for heating in winter, the working surface is exothermic and the reaction surface is endothermic.

At this time, when the reaction surface is an endothermic action and the temperature is lowered, the moisture of the surrounding air is condensed, which has a problem of further drying the indoor air in the dry winter.

Furthermore, condensed water may cause component corrosion or malfunction of the mattress device.

In addition, the condensate attached to the mattress device had to be removed regularly.

The present invention has been invented to solve the above problems, an object of the present invention is to provide a mattress device having a humidity control function by condensate evaporation.

Another object of the present invention is to provide a mattress device that can prevent component corrosion or malfunction by condensate.

The above object is, the mattress portion having a heat-resistant filled circulation tube is disposed inside, and having a heat-resistant layer portion is provided with a temperature sensor at a predetermined position; An operation unit coupled to the mattress unit by placing the circulation pipe and heating or cooling the heat medium; And an evaporation unit for collecting condensate resulting from the operation of the operating unit and evaporating the collected condensate.

Preferably, the operation unit, the heat sink filled with the heat medium; A thermoelectric module having a working surface in thermal contact with the heat medium of the heating sink and a reaction surface in contact with the working surface to heat or cool the heat medium; Forward and reverse switching circuit for switching the heating or cooling operation of the thermoelectric module; A pump for circulation of the heat medium; And a microprocessor controlling the forward / backward switching circuit according to the temperature value detected by the temperature sensing sensor, wherein the evaporator comprises: a condensate tank installed under the outer portion of the thermoelectric module; And an evaporation unit for heating and evaporating the collected condensed water of the condensate tank.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Mattress device having a humidity control function of the present embodiment is composed of a mattress unit 100, the operation unit 200 and the evaporator (240).

The mattress unit 100 includes a cover 110 covering the upper and lower surfaces and a cold / hot layer unit 120 having a predetermined thickness therein, and the circulation pipe 130 and the temperature sensing sensor filled with the heat medium in the cold / hot layer unit 120. 140 is located. The circulation tube 130 is a thin tube that is properly disposed so as to evenly pass through the entire inside of the cold / hot layer part 120, and both ends thereof extend to the outside of the cold / hot layer part 120, and the heat medium filled therein is mainly water. The temperature sensor 140 is installed at a predetermined position of the cold / hot layer unit 120 to detect the temperature of the cold / hot layer unit 120.

The operation unit 200 is installed outside the mattress unit 100 and includes a control unit 210, a heating sink 220, and a thermoelectric module 230.

The controller 210 includes an A / D converter 212 and a thermoelectric module 230 for converting a temperature value detected analog from the keypad 211 and a temperature sensor 140 equipped with a temperature setting switch, a power switch, and the like to digital. The microcomputer for storing the temperature value set in the forward and reverse switching circuit 213 and the keypad 211 for converting the direction of the current entering into the control unit and controlling the forward and reverse switching circuit 213 according to the temperature value detected by the temperature sensor 140. A processor 214.

The heating sink 220 is connected to both ends of the circulation pipe 130 and filled with a heat medium therein, and includes a pump 221. The pump 221 is operated by the submersible motor, and circulates the heat medium inside the circulation tube 130. The thermoelectric module 230 receives electricity from the controller 210 and includes a reaction surface 231 for heating / cooling the heat medium and a reaction surface 232 coupled to the opposite side of the operating surface 231. An inner heat radiation fin 236 is attached to the working surface 231, and the inner heat radiation fin 236 contacts the heat medium inside the heat sink 220 to change the temperature of the heat medium. The reaction surface 232 has an exothermic / endothermic reaction opposite to the action surface 231, and attaches an external heat dissipation fin 233 and a heat dissipation fan 234 that emit heat or cold air generated from the reaction surface 232. do.

In addition, a heating unit 235 is installed between the reaction surface 232 and the external heat dissipation fin 233 to heat the reaction surface 232. The kind of the heating unit 235 is not particularly limited, and for example, a PTC heater, a ceramic heater, a film heater, or the like may be used. The heating unit 235 operates only when the temperature of the reaction surface 232 decreases, that is, when heating the heat medium.

The evaporator 240 includes a condensate tank 241 and the evaporation unit 242. The condensate tank 241 is a place where water condensed from the external heat dissipation fin 233 falls and collects, and is located below the external heat dissipation fin 233. The evaporation unit 242 is connected to the condensation tank 241 to evaporate the water collected in the condensation tank 241, and has a general structure using heat or ultrasonic waves.

The mattress device having a thermoelectric module according to the present embodiment having the above configuration works as follows.

The microprocessor 214 compares the set temperature input by the user through the keypad 211 and the temperature of the mattress measured by the temperature sensor 140, and controls the reverse switching circuit 213 according to the result. The module 230 causes the heating medium to heat or cool. As a result, the temperature of the cold / hot layer unit 120 is close to the set temperature.

When the thermoelectric module 230 cools the heat medium, the working surface 231 is lowered in temperature, and the reaction surface 232 is raised in temperature. At this time, the working surface 231 absorbs heat from the heat medium so that the change in temperature is small, but the reaction surface 232 continues to rise in temperature. When the temperature difference between the working surface 231 and the reaction surface 232 becomes large, the thermoelectric module Since the efficiency of the 230 is not preferable, the heat is discharged through the external heat dissipation fin 233 and the heat dissipation fan 234 attached to the reaction surface 232.

On the contrary, when the thermoelectric module 230 heats the heating medium, the working surface 231 increases in temperature, and the reaction surface 232 decreases in temperature. At this time, the working surface 231 releases heat to the heat medium so that the change in temperature is small, but the reaction surface 232 continues to decrease in temperature. In order to increase the efficiency of the thermoelectric module 230, the heating unit 235 attached to the reaction surface 232 is operated to increase the temperature of the reaction surface 232 to reduce the temperature difference with the working surface 231. Accordingly, the temperature difference between the working surface 231 and the reaction surface 232 is not large, thereby increasing the efficiency of the thermoelectric module 230.

When the thermoelectric module 230 heats the heating medium, the working surface 231 increases in temperature and the reaction surface 232 decreases in temperature. When the temperature of the reaction surface 232 is lowered than the temperature of the ambient atmosphere, heat exchange with the atmosphere through the external heat radiation fins 233.

At this time, since the temperature of the external heat dissipation fin 233 is low, moisture in the air condenses on the external heat dissipation fin 233, and as the moisture in the air condenses, the air in the room is dried. If the amount of condensation increases, the water is agglomerated and the water droplets increase and fall from the external heat dissipation fin 233 to collect in the condensate tank 241.

In this way, the water collected in the condensate tank 241 is evaporated by the evaporation unit 242, and is released into the atmosphere. Therefore, by increasing the humidity of the dry room, you can create a comfortable environment.

Meanwhile, according to another embodiment of the present invention, it may include a humidity setting unit. The humidity setting unit may include a humidity sensor, a setting humidity input unit, and an on / off switch. Therefore, the user can set the desired humidity, when the humidity is reached, the on-off switch stops the operation of the evaporation unit, and thus the evaporation of the condensate is stopped. After the humidity drops below the set humidity, the humidity sensor detects this and restarts the evaporation unit to resume the operation of increasing the humidity again.

In the above, the present invention has been illustrated and described with respect to specific embodiments. However, the present invention is not limited only to the above-described embodiment, and those skilled in the art to which the present invention pertains can make various changes without departing from the technical spirit of the present invention. Therefore, the scope of the present invention should not be limited to the specific embodiments, but should be construed as defined by the appended claims.
