Description

Dehumidifier For Home Using The Thermoelectric Element

The present invention relates to a household dehumidifier having a function of humidification and air cleaning, and more specifically, to force suction of contaminated indoor air and to first filter through an internal filter, and to include moisture contained in the air by the thermoelectric assembly. And it relates to a dehumidification apparatus for home use having a humidification function and air cleaning function, as well as a dehumidification is made by adsorption with moisture, fine dust, odors and the like condensed with moisture.

In recent years, among the home appliances that are being released in recent years, air cleaners or dehumidifiers are released separately according to each use purpose, and have been well received by consumers by improving living standards.

In general, the former air purifier has been continuously developed by adding the basic filter method to the negative ion function. The latter dehumidifier has simple functions such as refrigerant circulation method and thermoelectric element control function according to time and pollution degree. It is spreading as a product with improved performance due to the technical improvement of.

For example, Patent Document No. 376384 (an air purifier having a dehumidifying device using a thermoelectric semiconductor element) and Patent No. 709499, which have been proposed as prior arts, will not be described in detail.

However, in the former case, a thermoelectric element is used, but after dehumidifying the air sucked from the outside through the inlet port, the air flowing from the other inlet located at the upper part is purified while going to the outlet port, and then mixed and dried together with the dehumidification air. This method is not desirable in terms of efficiency.

In addition, if the air sucked from the inlet passes through the cooling plate first, in winter, spring, and autumn, when the room temperature is not high, as soon as cold air enters, the cold plate first occurs in the cold cooling plate, which significantly reduces the dehumidification effect. Will occur.

In the latter case, the air is sucked from the upper part and the purified air is discharged to the lower part. In this case, the hot air from the thermoelectric element is discharged directly to the upper part of the device instead of the lower part of the room. There is a big contradiction in its efficiency.

Here, in the case of the dehumidifier using the thermoelectric element, ΔT (delta tee) generated from the heat sink and ΔT (delta tee) generated from the cooling plate do not cancel each other, and thus the heat generation is much higher, so the air coming out of the device is naturally indoors. Because it is supposed to go up.

In other words, in the case of dehumidification using a thermoelectric element, considerable heat is emitted from the heat sink and cooling heat is discharged from the cooling plate, but since the cooling heat is consumed as heat of condensation that condenses moisture, thermal equilibrium does not occur. There is a problem that the air is always higher than the suction temperature.

Due to this, the registered utility model No. 413931, which was previously proposed by the applicant of the present invention to overcome the problems of the prior art as described above: a number other than the household electronic dehumidifier (hereinafter referred to as 'prior art') It has already been known as a matter, a detailed description thereof will be omitted.

In the prior art, in the winter or spring and autumn, the temperature of the air is relatively low, so that the incoming air passes through the cooling plate inside the dehumidifier first, and dehumidification occurs. There was a problem that the dehumidification effect does not occur at all.

In addition, there are disadvantages in that it is insufficient to filter dust or foreign substances having relatively large particles, and defects such as deterioration of the performance of the apparatus are generated as the dust or foreign substances are adsorbed on the thermoelectric element assembly in large quantities. Thus, although the thermoelectric element has some air cleaning function by the adsorption of the cooling plate, there is a limit in its performance, which requires continuous improvement.

In addition, as bacteria, such as harmful to the human body, grow in the dehumidifier, such as contaminating the indoor environment, there is a need for continuous washing and maintenance.

Of course, the economic burden of separately purchasing a dehumidifier or an air purifier as well as a humidifier in a limited indoor space such as a home or an office, and an increase in unnecessary energy consumption by using two products separately, as well as inefficient space utilization There was this.

In addition, in recent years, well-being consumers tend to pursue the convenience of a complex device having a simple, diverse, and convenient function, so that the home dehumidifier having the humidification and air cleaning functions of the present invention can be used very effectively through the dehumidification function.

The household dehumidifier having the humidification and air cleaning functions of the present invention will be more readily understood by the following description of the operating conditions.

First, when the power is connected to the power supply unit 65 and the power switch of the control unit 60 is placed in an ON state, control for operating the device in the control panel 61 is performed.

First, in the initial mode, the air cleaning and dehumidification functions are performed at the same time, and only the air cleaning function can be performed according to the setting of the operation mode switch of the controller. Here, when the desired humidity value is set by the humidity setting volume, the thermoelectric element 32 and the suction fan 40 are automatically activated and deactivated according to the humidity sensed by the humidity sensor 13.

In addition, when the water tank 50 is full of condensed water, the water level indicator is turned on and the operation of the device is temporarily stopped. Thereafter, the collection tank is taken out from the case to discharge condensate, and then remounted to switch to the initial initial mode to resume new dehumidification and cleaning activities.

More specifically, the dehumidifying device having a humidifying and air cleaning function of the present invention forcibly sucks contaminated air from the inside of the case through the suction port 12 by the rear suction fans 40 and 40a of the case 10. The filter 18 in front of the lower surface filters dust or foreign matter in the air and cleans the primary. The filter 18 is very beneficial to the human body by the antibacterial action of charcoal, loess, along with dust and foreign matter, and also prevents harmful bacteria such as bacteria, as well as removing odors.

Next, the primary clean air is dehumidified while passing through the thermoelectric element assembly 30, and at the same time, the dehumidification and secondary adsorption treatment of yellow dust, fine dust and odor by surface tension of water condensed on the cooling plate and Air cleaning is done. In other words, when the thermoelectric element 32 is applied with DC power, the temperature rises on one side and the other side is cooled by the Paltier effect.

Here, the air sucked through the filter is heat-exchanged while passing through a relatively warm heat sink 31 in front of the cartridge, the temperature is raised, then turning through the air passage provided on both sides of the cartridge to the rear suction fan 40 of the cartridge After passing through, it is in contact with the internal cooling plate 33.

At this time, the warm air passing through the heat sink 31 is in contact with the cold plate 33 in the low temperature state, the dehumidification efficiency is significantly increased by the coagulation action due to the temperature difference, fine dust mixed with moisture in the air, yellow sand, As odor component is adsorbed, it flows down with water to purify.

The clean air purified as described above is discharged to the exhaust port 19.
