The present invention relates to a bed capable of cooling the bed top plate material using thermoelectric semiconductor. Since the thermoelectric semiconductor driving power source uses low voltage direct current electricity, there is no risk of electromagnetic waves, fire, electric shock, etc. This has the advantage of being used with confidence.

In particular, the polarization of the thermoelectric semiconductor is reversed to make the top plate hot in winter, and the top plate cool in the summer, and the heat sink and cooling fan installed in the lower part of the thermoelectric semiconductor are improved for cooling or heating with a low heat dissipation structure. It relates to the cold temperature of the bed top plate using a thermoelectric semiconductor so as to improve the efficiency.

The bed only for the thermal effect has a problem of electromagnetic waves, fire, electric shock, etc., because the use of alternating current generally has a problem of avoiding the use of the elderly and pregnant women as well as the public.

An object of the present invention for solving the problems as described above is to have a function to cool the bed top plate and to make the bed top plate in the winter and to cool the top plate in the summer season by using a polarized electric switch configured in the temperature controller It can be used by the elderly and pregnant women with low risk of electric wave, fire, electric shock, etc. by using low voltage direct current while providing cold and hot function.

In the bed top plate cold temperature apparatus with a thermoelectric semiconductor according to the present invention, the top plate 200 is formed in the bed frame 100 on the top as shown in FIGS. 1 to 4, and the top plate 200 and the heat transfer plate 10 are provided. In close contact with the fastening after applying a heat-dissipating grease to the upper end of the heat transfer plate 10 in order to increase the thermal conductivity.

The fastening bolt 11 and the aluminum plate 10 and the heat dissipation end 30 which can be fastened to the heat sink 30 with the aluminum plate 10 and the thermoelectric semiconductor 20 interposed therebetween. In order to prevent heat conducting through the fastening bolt 11 at the time of fastening, the heat insulating color 12 penetrates from the fastening hole of the heat transfer plate 10 to the fastening hole 31 of the heat dissipation plate and to increase the thermal conductivity in the upper and lower portions of the thermoelectric semiconductor 20. The heat dissipation grease process is inserted between the heat transfer plate 10 and the heat dissipation plate 30 and fastened to the fastening bolt 11 by using the fastening nut 31.

The blower tube 33 and the cooling fan 34 which help the heat dissipation effect are integrated into the blower tube fastening hole 36 by using the blower tube fastening bolt 35.

Below is a look at the bed top plate cold-temperature method using a thermoelectric semiconductor according to the present invention configured as described above.

First of all, the peltier effect is explained by applying a direct current electric current to a thermoelectric module. At a metal / semiconductor contact that is negatively charged, electrons absorbing thermal energy from the surroundings move into the thermoelectric semiconductor and one side is cooled. This happens and the other side is a fever.

In this state, if the polarity of the electrode is changed, the cooling side generates heat and the heating side generates cooling.

Using this phenomenon, bed tops can be cold and warm.

First, the cooling of the upper plate during summer use will be described.

When the temperature controller 40 of FIG. 4 selects cold / cold temperature of the polarity telephone part 41, a low voltage direct current is applied to the thermoelectric semiconductor through a relay contact of the power supply relay part 42, and a Peltier phenomenon occurs.

Here, the heat transfer plate 10 becomes cold and the heat sink 30 becomes hot.

Cooling efficiency is maximized only when the heat of the heat sink is efficiently released, so the cooling fan 34 formed integrally with the air blower 33 on the heat sink 30 is blown to cool the heat sink 30 to cool the heat sink 10. It can be maximized.

As described above, since the heat transfer plate 10 is cold and the heat sink 30 is hot, the heat insulating material 300 is treated at the interface between the heat insulation collar 12 and the heat transfer plate 10 and the heat sink 30 which can prevent the conduction of heat.

In contrast to the above operation method for the winter heat effect by selecting the on of the polarity switching unit 41 can be obtained the heat effect of the top plate material as opposed to the top plate cooling.

According to the present invention as described above, it can be used according to the user's choice during the winter season, summer season can be hot or cold, can be used according to the four seasons sense and risk factors such as electromagnetic wave fire electric shock by using DC low voltage electricity, not AC electricity There is no effect that the elderly and pregnant women can use with confidence.

Meanwhile, the present invention exemplifies the best embodiment thereof, but is not limited thereto, and if the present invention can be practiced without departing from the scope of the present invention, it may be considered to change the embodiments described so far. Of course.
