Description

DISHWASHER {DISH WASHER}

The present invention relates to a dishwasher, and more particularly, to a dishwasher having improved drying performance.

In general, the dishwasher is a device for sanitary and efficient dish washing, and performs a function of washing the dirty dishes and drying the dishes.

Drying of the dishwasher promotes the evaporation of the water on the dishwasher by washing and rinsing by using high temperature water and raising the temperature inside the dishwasher. Evaporated water vapor is condensed in the cooling ducts or removed using an absorbent. Alternatively, condensation from cooling ducts and an absorbent may be used together.

The use of the absorbent requires drying (regeneration) of the absorbent in order to enable the absorbent to absorb water vapor in the next cycle. Regeneration of the re-humidant is performed by heating the absorbent during the washing and rinsing process before the drying process using a heater provided separately.

That is, during the washing or rinsing process, the moisture absorbent is heated by the heater to evaporate the moisture from the absorbent, and the vaporized vapor is sent into the dishwasher. After the washing process, the previously absorbed moisture absorbs the moisture again. By doing so, the dishes are dried.

However, there is a problem that the drying efficiency is lowered due to the wet steam generated during the regeneration process, thereby increasing the energy required for the drying process.

The dishwasher according to the present invention aims to increase drying efficiency and save energy in the process of drying dishes.

2 is a cross-sectional view showing a side of the dish washer 2 according to the first embodiment of the present invention, Figure 3 is a plan view of FIG.

The dishwasher 2 according to the first embodiment of the present invention includes a case 10, a washing tank 20 provided inside the case 10 to receive dishes, and a circulation unit communicating with the washing tank to circulate air. Include.

The circulation unit is in communication with the washing tank 20, the inlet 100 is introduced into the air, the inlet 100 is in communication with the condensation unit (210,220), condensation unit (210, 220) for condensing water vapor in the air and includes an absorbent The absorbent unit 300 includes a heater 40 generating heat to regenerate the absorbent 310, and a discharge port 600 communicating with the washing tank 20 and discharging air introduced into the inlet 100.

Hereinafter, the drying process of the dishwasher 2 will be described based on the circulation unit.

During the drying process, as the inside of the washing tank 20 becomes high temperature, the moisture in the dishes is evaporated to become water vapor. Air containing the steam (hereinafter referred to as 'air') is introduced into the circulation unit through the inlet (100).

Inlet 100 may be located above the washing tank (20). Inlet 100 may be provided with a cap 110 to prevent the water condensed from the first condensing unit 210 is introduced into the washing tank (20).

The air introduced through the inlet 100 is condensed while passing through the first condenser 210. The condensation unit 210 or 220 may increase the surface area to improve the degree of condensation of water vapor in the air (hereinafter referred to as 'condensation efficiency'). The air condensed with a certain amount of water vapor passing through the first condenser 210 passes through the absorbent part 300 including the absorbent 310.

The absorbent part 300 may include a absorbent plate 320 on which the absorbent 310 and the absorbent 310 are placed.

The moisture absorbent 310 absorbs moisture in the air flowing through the circulation unit and is made of a material having excellent hygroscopicity. As the material of the absorbent 310, zeolite, active carbon, super absorbent polymer, porous fiber, or the like may be used.

Zeolites are minerals that are aluminum silicate hydrates of alkali and alkaline earth metals, and are characterized by colorless or white translucent color. Active carbon is highly adsorptive, and most of its constituents are carbonaceous materials, which absorb gas or moisture with an adsorbent. Super Absorbent Polymer is a resin that absorbs water from tens to hundreds of times its own weight. Since the material itself absorbs water, it absorbs more water than cotton wool or cotton cloth, and does not emit water at moderate pressure. There is a characteristic.

The moisture absorbent 310 includes various forms such as granular, powder, granule, or fibrous form. In order to increase the surface area in contact with the air, it is possible to place the layer layer while spreading wide. At this time, the absorbent plate 320 may be disposed in the middle so that the absorbent 310 may be placed.

As the air passes through the moisture absorbent unit 300, the moisture in the air moves to the moisture absorbent 310, thereby lowering the moisture content. As the humidity of the air is lowered, the moisture absorbent 310 contains moisture, and as the moisture absorbent 310 becomes more absorbent, the efficiency of the moisture absorbent 310 is lowered. Therefore, in order to reversibly use the absorbent 310, a regeneration process for removing moisture absorbed by the absorbent 310 is required.

The first condensation unit 210 and the moisture absorbent 300 may be located above the washing tank 20. In this case, the inlet part 100 is located in the front of the washing tank 20 (where 'forward' refers to the direction in which the door 40 is located) so that the first condensing part 210 and the moisture absorbent part 300 are positioned. You can make room for it.

The air having a low moisture content while passing through the moisture absorbent unit 300 passes through the second condensation unit 220 and undergoes a condensation process once again. The second condensation unit 220 may be located at the side of the washing tank 20. When the second condensation unit 220 is located on the side of the washing tank 20, it may be located in the space between the washing tank 20 and the case 10 without providing a separate space, so that the compact dishwasher (2) can help to produce.

The outlet 600 may be located below the side of the washing tank (20). The second condenser 220 is to increase the amount of water condensed by condensing the air while the air passing through the moisture absorbent 300 is discharged to the outlet 600.

The process of deodorizing the air by the moisture absorbent 310 is an exothermic process. Therefore, the air temperature rises while passing through the moisture absorbent unit 300. This increase in air temperature increases the condensation efficiency of the second condenser 220. Therefore, to pass the second condensation unit 220 before discharging the air having a temperature rise while passing through the moisture absorbent unit 300 to the discharge port 600, there is no second condensation unit 220, or Improves drying efficiency compared to when positioned forward.

The drying process may repeat the circulation of the circulation unit two or more times. As the number of repetitions increases, more moisture in the dishes evaporates, improving the degree of drying, while consuming more energy. Therefore, the second condensation unit 220 of the present invention condenses the air passing through the moisture absorbent unit 300 once more, thereby reducing the number of repetitions of the air circulating through the circulation unit, which consequently saves energy. It has an effect.

Hereinafter, the regeneration process of the absorbent 310 will be described.

The moisture absorbent 310 absorbs moisture in the air during the drying process, thereby increasing the moisture content. This acts as a factor to lower the moisture absorption efficiency. Therefore, in order to use the absorbent 310 reversibly, the amount of moisture contained in the absorbent 310 should be reduced.

The process of heating the moisture absorbent 310 so that the moisture absorbed by the moisture absorbent 310 can be released again is called a regeneration process. The circulation unit may include a heater 400 for regeneration of the moisture absorbent 310. The heater 400 is a device that generates heat to heat the moisture absorbent 310 to evaporate the moisture absorbed by the moisture absorbent 310. The air whose humidity is increased due to the evaporated water is condensed while passing through the second condensation unit 220 and discharged through the outlet 600.

The air discharged through the outlet 600 is introduced again through the inlet 100 to condense in the condensing unit 210 and 220 while circulating the circulation unit, thereby lowering the humidity. During the regeneration process, the moisture absorbent 310 is dried to restore the moisture absorption efficiency, and the air containing moisture of the moisture absorbent 310 is also condensed in the process of circulating the circulation unit so that the drying efficiency may not be reduced.

The regeneration process can be carried out when no drying process takes place. That is, not only washing and rinsing but also regenerating during the rest period can increase the drying efficiency in the next drying process.

In addition, the conventional method includes directly discharging moisture to the outside to remove moisture generated during the regeneration process. However, as the water vapor generated during the regeneration process is immediately condensed through the second condenser 220, there is no need to discharge moisture to the outside. This eliminates the risk factors associated with the discharge of hot and humid air and prevents the odor from the exhausted air.

The circulation unit may include a circulation fan 500 to promote circulation of air. The circulation fan 500 circulates the air so that the air introduced into the inlet 100 may flow out through the outlet 600. To this end, the circulation fan 500 imparts kinetic energy in the air circulation direction. The circulation fan 500 may be located in front of the heater 400. In this case, by absorbing the heat of the heater 400 there is an advantage that can promote the circulation of the air temperature rises. Of course, the circulation fan 500 may be spaced apart from the heater 400.

4 is a cross-sectional view showing a side of the dishwasher 3 according to the second embodiment of the present invention, Figure 5 is a plan view of FIG.

In the dishwasher 3 according to the second embodiment of the present invention, the inlet 100 and the first condenser 210 are positioned at the upper portion of the washing tank 20, and the moisture absorbent 300 and the second condenser 220 are disposed. , And the outlet 600 may be located on the side of the washing tank (20).

Compared with the dishwasher 2 according to the first embodiment of the present invention, the space in which the first condenser 210 may be increased may improve condensation efficiency.

At this time, the heater 400 may be located in close proximity to the absorbent 300 for efficient regeneration of the absorbent 300. 4 and 5 illustrate that the heater 400 is positioned at the end of the first condensation unit 210. Alternatively, the heater 400 may be positioned immediately above the moisture absorbent 300.

Positioning the absorbent unit 300 between the side of the washing tank 20 and the case 10 can help to produce a compact dishwasher 3 using space efficiently. The second condensation unit 220 connected to the moisture absorbent unit 300 may also be located between the side of the washing tank 20 and the case 10.

6 is a cross-sectional view showing a side of the dishwasher 4 according to the third embodiment of the present invention, Figure 7 is a bottom view of FIG.

In the dishwasher 4 according to the third embodiment of the present invention, the inlet 100 may be located at the side of the washing tank 20, and the outlet 600 may be located at the bottom of the washing tank 20. The air introduced into the inlet 100 moves through the first condensing unit 210 positioned between the side of the washing tank 20 and the case 10 to the hygroscopic unit 300.

The moisture absorbent 300 and the second condenser 220 may be located at the bottom of the washing tank 20. In order to prevent the water condensed in the first condenser 210 from flowing into the moisture absorbent 300, the first condenser 210 may include a drip tray 700.

The heater 400 may be located between the first condenser 210 and the moisture absorbent 300. 6 and 7 illustrate that the heater 400 is positioned at the end of the first condenser 210. Since the heater 400 is located near the moisture absorbent 300, heat may be transferred to the moisture absorbent 300 without loss.

The outlet 600 may be located in front of the bottom of the washing tank (20). This is to secure sufficient space for the second condensation unit 220 to be located. The outlet 600 may be provided with a cap 610 to prevent the moisture in the washing tank 20 to penetrate.
