Description

[0001] LAUNDRY TREATING MACHINE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clothes processing apparatus, and more particularly, to a clothes processing apparatus in which separate cooling water is supplied to an inner surface of a tub and a portion of the inner surface of the tub is cooled to generate condensed water.

Generally, the clothes processing apparatus is exemplified by a washing apparatus, a drying and washing apparatus, and the like. Here, the washing machine removes various pollutants adhered to clothes, bedding, etc. by using the emulsification action, the frictional action of the water stream due to the pulsator or the rotation of the drum, and the impact acting on the laundry. In the automatic laundry washing machine recently introduced, a series of strokes leading to a washing course, a rinsing course, a dehydrating course and the like are automatically carried out without user's manipulation in the middle.

In addition, the drying and washing machine is a type of washing machine capable of performing the function of the above-described washing machine and washing and drying the laundry. Such a dry-type washing and drying machine includes a condensing type washing and drying machine in which air in the tub is drawn out, water in the air is removed by condensation water, and then heated and then introduced into a tub.

Hereinafter, a conventional condensing type drying and washing apparatus according to the prior art will be briefly described with reference to FIG. As shown in the drawing, the drying and washing machine 10 includes a cabinet 11 forming a receiving space therein, a tub 12 accommodated in the cabinet 11, A condensing duct 14 formed outside the tub 12 so that the air containing moisture generated from the tub 12 can be condensed and a condensing duct 14 formed along the flow direction of the air, A heating duct 15 connected to the downstream side of the condenser duct 14 and heating the air by the heater 16 and providing the air to the inside of the tub 12, 15 for circulating the air through the air blowing fan 17.

The air to be moved to the air blowing fan 17 during the drying of the laundry is heated by the heater 16 provided in the heating duct 15 and the heated air is supplied to the tub 12, And the laundry is dried by the rotation of the drum 13 and hot air.

The heated air after drying the laundry is converted into humid air as the laundry is dried, and the moisture is removed from the condensing duct 14 by flowing into the condensing duct 14 at the tub 12. Here, the condensing duct 14 is supplied with additional cooling water for condensing moist air. Meanwhile, the air introduced into the condensing duct 14 is supplied to the heating duct 15 again by the blowing fan 17, and the air is circulated by repeating the above-described process.

Meanwhile, in the case of the above-described condensing duct 14, it is provided in the form of a pipe in consideration of the air flow capacity of the air blowing fan 17 and the smooth flow of the air, and is heat exchanged with the humid air from the inner surface of the condensing duct 14 The moisture contained in moist air is condensed to remove moisture. For this purpose, in order to condense moisture in the humid air introduced into the condensing duct 14, a large amount of cooling water must be continuously supplied during the drying process of the laundry.

However, since the conventional condensing duct 14 has a relatively small area for heat exchange with humid air, a relatively large amount of cooling water must be supplied for a long period of time, thereby wasting cooling water.

When the laundry is dried, the lint included in the laundry may flow along with the air through the condensing duct 14 and may remain in the condensing duct 14, the blowing fan 17, the heating duct 15, and the like. Therefore, the lint remaining in the condensing duct 14 can reduce the efficiency of the condensing duct, and the lint remaining in the blowing fan 17 can cause the blower to fail, and the lint remaining in the heating duct 15 can be heated There is a problem that the heater 16 provided in the duct 15 may fail or fire may occur.

Meanwhile, in the case of the clothes processing apparatus 100 having the above-described structure, the tub 120 is cooled to generate washing water for washing and rinsing, washing water for washing the lint filter 162, Supply of cooling water is required.

That is, a structure for supplying water separately to the water supply unit 180 for washing and rinsing, the filter washing unit 190 for washing the lint filter, and the cooling water supply unit 200 for cooling the tub 120 It is necessary.

Hereinafter, the structures of the water supply unit 180, the filter cleaning unit 190, and the cooling water supply unit 200 and the structure for supplying water will be described with reference to the drawings.

6, an outer water supply source (not shown) is connected to the inside upper portion of the clothes processing apparatus 100 by respective components (for example, a water supply unit 180, a filter cleaning unit 190, a cooling water supply unit 200, And a valve unit 170 for selectively or simultaneously supplying the water supplied from the water supply unit (not shown).

Here, the valve unit 170 is composed of a plurality of valves corresponding to the respective components to which water is supplied. That is, a water supply valve 172 for controlling the supply of washing water (or rinse water) to the water supply unit 180, a water wash valve 174 for controlling the water supply to the filter washing unit 190, And a cooling water valve 176 for controlling the cooling water supplied to the inner surface of the casing 120. On the other hand, in the case of the valve unit 170, a separate valve may be further provided when there are further additional configurations using water (for example, steam generator, etc.).

The water supply unit 180 includes a water supply line 182 for supplying wash water from the water supply valve 172 and water supplied through the water supply line 182 on the water supply line 182, And a detergent supply device 184 into which the detergent is input so as to be introduced into the inside of the detergent dispenser 120. The washing water having passed through the detergent supply unit 184 is supplied into the tub 120 from the front of the tub 120 through a separate hose.

The filter cleaning unit 190 includes a washing water line 192 for supplying washing water from the washing water valve 174 and an air return port 161 which is fixed to the inside of the air return port 161 through the air return port 161, And a spray nozzle 194 connected to the wash water line 192 from the outside of the spray nozzle 161 (see FIG. 7).

The injection nozzle 194 includes a coupling part 195 fixed to the inside of the air recovery port 161 and connected to the washing water line 192 and a plurality of nozzles 170 coupled to the coupling part 195, And a diffusion portion 196 for spraying the washing water on almost the entire surface of the lint filter 162. [ Here, a hollow (not shown) communicating with the coupling part 195 and the diffusion part 196 is formed. Since the inner and outer structures of the injection nozzle 194 can be variously implemented, a detailed description thereof will be omitted.

The cooling water supply unit 200 is for removing moisture from the humid air by drying the laundry by generating condensed water on the inner circumferential surface of the tub 120 by using the inner circumferential surface of the tub 120 as a cooling surface. The cooling water supply unit 200 includes a cooling water line 210 supplied from the cooling water valve 176 and a cooling water nozzle 220 positioned on the rear upper side of the tub 120 and injecting cooling water on the inner rear surface of the tub 120. [ Respectively.

Hereinafter, the cooling water supply unit 200 will be described in detail with reference to the accompanying drawings. FIG. 8 is a schematic view showing the inner rear surface of the tub of the clothes processing apparatus according to the present invention, and FIG. 9 is a partial sectional view showing the line A-A 'in FIG.

As shown in FIGS. 8 to 9, the cooling water nozzle 220 of the cooling water supply unit 200 is provided at the upper portion of the rear side of the tub 120. Preferably about 20 degrees with respect to a vertical plane with respect to the rotary shaft 135, more preferably about 20 degrees with respect to a vertical plane with respect to the rotary shaft 135, with respect to the air recovery port 161 formed in the tub 120, It is located between angles of ~ 40 °. The reason why the cooling water nozzle 220 of the cooling water supply unit 200 is located at such a position is that the cooling water sprayed from the cooling water nozzle 220 can smoothly flow along the rear surface of the tub 120.

That is, when the cooling water nozzle 220 is positioned at the upper center of the tub 120, the cooling water injected from the cooling water nozzle 220 flows along the rear gasket 126 and the tub back wall 125 coupled to the rear surface of the tub 120 And flows in the vertical direction. In this case, the area of the cooling water flowing down is small, and the time for cooling the rear surface of the tub 120 is short, thereby deteriorating the cooling effect.

When the cooling water nozzle 220 is located at the outermost side of the tub 120, the area of the cooling water injected from the cooling water nozzle 220 is small and the time for cooling the rear surface of the tub 120 is short, 120 is lowered.

The cooling water jetted from the cooling water nozzle 220 is relatively moved along the rear surface of the tub 120 when the water is provided at a position of about 20 to 40 degrees relative to the vertical surface in the direction opposite to the air recovery port 161, And the tub 120 flows downward over a wide area, so that the cooling efficiency can be increased.

That is, the generation of condensed water using the inner surface of the tub 120 can generate condensed water using a larger area than that of the condensed water generating structure using the conventional condensed duct, thereby improving condensate production efficiency.

Meanwhile, the cooling water nozzle 220 of the cooling water supply unit 200 needs to spray the cooling water supplied from the cooling water line 210 widely on the rear surface of the tub 120. The cooling water nozzle 220 has a hollow body and has a connecting end 222 connected to a cooling water line 210 at an upper portion thereof and a nozzle end 226 located at an inner side of the tub 120 at a lower portion thereof. Is formed. Between the connection end 222 and the nozzle end 226, a locking end 224 is formed for the cooling water nozzle 220 to be installed on the tub 120. The lower end of the nozzle stage 226 is further provided with a reflection plate 228 for reflecting the cooling water supplied to the rear side of the tub 120 to be diffused.

Hereinafter, the operation of the clothes processing apparatus of the present invention as described above will be described. Here, the filter cleaning unit and the cooling water supply unit, which are the main components of the present invention, operate during the drying process of the clothes processing apparatus 100. The description of the washing and rinsing processes of the clothes processing apparatus 100 will be omitted and only the drying process related to the present invention will be briefly described. In the meantime, each element mentioned below should be understood with reference to the above description and drawings.

First, as the drying process is progressed, the air blowing fan 163 of the air supply device 160 is operated, and the air inside the tub 120 is sucked through the air return port 161 according to the operation of the air blowing fan 163, And is moved to the side of the heating duct 164 by the blowing fan 163. The air that is moved to the heating duct 164 is heated by the heater provided in the heating duct 164 and supplied to the inside of the tub 120 through the air outlet 165.

The air supplied to the inside of the tub 120 causes the laundry in the tub 120 (specifically, the drum 130) to dry. The air dried by the laundry is converted into a humidifier by the moisture evaporated in the laundry, and is then introduced into the air recovery port (161) and circulated.

Meanwhile, the lint generated in the laundry in the drying process is filtered by the lint filter 162 of the air recovery port 161, and the filtered lint is removed during the drying process or the washing / rinsing process, The dust is separated from the lint filter 162 and flows into the tub 120 and discharged to the outside of the clothes processing apparatus 100 by the drain of the tub 120. [

Also, as the above-described process proceeds, the moisture generated in the laundry is circulated like air. The removal of moisture through the cooling water supply unit 200 is performed. First, when cooling water is supplied under the control of the cooling water valve 176, the cooling water is moved along the cooling water line 210 and is sprayed to the rear surface of the tub 120 by the cooling water nozzle 220. The cooling water sprayed on the rear surface of the tub 120 flows down along the rear surface of the tub 120 to cool the inner circumferential surface of the tub 120. [ The moist air exchanges heat with the surface of the tub, and the moisture contained in the humid air condenses on the rear surface of the tub 120 to generate condensed water.

On the other hand, the cooling water supplied by the cooling water supply unit 200 is discharged to the outside of the clothes processing apparatus 100 through the drainage part of the tub 120 after cooling the rear surface of the tub 120. Here, the cooling water supply time and supply interval supplied by the cooling water supply part 200 are formed to be shorter by a shorter time and interval than the drainage part. In this case, the time taken for the supplied cooling water to stay in the tub becomes longer, and the cooling effect of the tub is further increased. Preferably, the cooling water supplied by the cooling water supply unit 200 is supplied for 3 to 5 seconds while it is stopped for 5 to 7 seconds to several to several tens of times. Then, the cooling water drained from the drainage section is drained for 10 to 20 seconds, and the drainage is repeated for several to several tens of times for 240 to 270 seconds.

Meanwhile, in the present invention, humid air having a high temperature stays in the tub 120, and air having a relatively lower temperature than the inside of the tub 120 stays outside the tub 120. Therefore, even if the washing water is not supplied from the cooling water supply unit 200, condensation may occur on the inner circumferential surface of the tub 120 due to a temperature difference between the inside and the outside of the tub 120.

In this case, the condensation amount can be relatively increased as compared with the case of using the condensing duct according to the prior art. That is, in the case of the conventional condensing duct, condensation is induced in an area relatively smaller than the inner circumferential surface of the tub 120. However, when inducing condensation on the inner circumferential surface of the tub 120 as in the case of the present invention, the cooling surface for condensation is relatively increased as compared with the condensed duct. Therefore, the condensation efficiency can be increased because the condensation surface is relatively formed as compared with the conventional technology using the condensation duct.

Furthermore, by supplying the cooling water to the rear surface of the tub 120, it is possible to further increase the cooling efficiency than when the cooling water is not supplied.

As described above, according to the clothes processing apparatus of the present invention, since the inner surface of the tub is formed as a condensing surface to remove the moisture of the hot air dried by the laundry, the condensing surface is wider than the condensing structure using the existing condensing duct, And it is possible to prevent the cooling water for condensation from being wasted.

In addition, the present invention has a lint filter for filtering the lint contained in air circulated after drying the laundry, thereby preventing a failure of the clothes processing apparatus by the lint.

Further, the lint filter can be easily cleaned by providing a filter cleaning structure for maintenance of the lint filter for filtering the lint contained in the circulated air after the laundry is dried.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, The present invention may be modified in various ways. Therefore, modifications of the embodiments of the present invention will not depart from the scope of the present invention.
