Description

Drying Washing Machine {WASHING MACHINE WITH DRY APPARATUS}

The present invention relates to a washing machine, and more particularly, to a dry washing machine having a structure including a heater equipped with a far infrared ray emission function.

In general, a washing machine is mainly for washing clothes by a mechanical operation through an electric motor. The washing machine is classified into an agitator type, a drum type, and a pulsator type according to its structure and washing method. , Roughly, a washing unit directly contributing to washing, a driving unit for supplying power for operation of the washing unit, and a case forming an outer shape, and the washing machine provided with a drying function further includes a drying device.

In the case of the washing section, for example, a spiral winding type washing machine, as shown in FIG. 1, the storage tank 12 installed in the case 10, the washing tank 14 embedded in the storage tank 12, and the washing tank 14 are located in the washing tank 14. It includes a pulsator (16) connected to the drive motor 20 and the transmission 22 and a supply, drain valve (not shown), etc. The reservoir 12 is a suspension in the case 10 It is supported by a mechanism (not shown), and the washing tank 14 is provided with a structure in which a plurality of dehydration holes 14a are provided on the wall thereof and rotatable by the drive motor 20.

In addition, the drying apparatus 30 for a drying function includes a heater 32 disposed above the washing tank 14, a blowing fan 34 provided at one side of the heater 32, and a heater (from the blowing fan 34). 32 is provided between the blower case 36 and the blower case 36 and the reservoir 12 to form a flow path extending over the reservoir 12, and the reservoir 12 generated when the washing tank 14 rotates. The bellows pipe 38 which forms a flow path to the washing tank 14 side, absorbing a vibration suitably is comprised.

According to the so-called dry washing machine equipped with a drying function configured as described above, the washing water and the laundry by the rotation of the pulsator 16 after the water supply stroke and the washing water is supplied to the washing tank 14 by the water supply valve. A washing stroke which is stirred for a predetermined time, and after the washing stroke is finished, the washing water is drained through the drain valve, and then rinsed again to rinse the laundry for a predetermined number of times, and after the rinsing stroke is finished, the washing tank 14 is rotated at a high speed to wash the laundry. After the dehydration stroke to dehydrate, and after the dehydration stroke, the drying stroke to dry the laundry by the drying device 30 proceeds sequentially to complete the entire washing process.

Here, the drying stroke is discharged into the washing tank 14 that is heated by passing the heater 32 through the heater 32 and then slowly rotates by the blowing operation of the blower fan 34 in the heating state of the heater 32. In this drying process, according to the drying process, the water remaining in the laundry is evaporated by the high temperature dry warm air (indicated by the arrow shown in the drawing) sprayed into the washing tank 14, so that the laundry is dried, so that the laundry is removed from the washing machine and dried. The convenience at the time of washing increases, such as not having to perform a drying operation.

However, according to this prior art, the heater 32 is composed of a heating wire and a sheath surrounding the heat conducting only a simple heating action, convection due to the warm air circulating in the washing tank 14 through the heater 32 Since the drying operation is performed only by heat, when a large amount of laundry is piled up or piles up, there is a problem that drying is not performed properly because heat is not evenly transmitted to the laundry below.

The present invention has been made to solve the above-mentioned conventional problems, by comprising a heater equipped with a far-infrared emission function of the combined dry washing machine exhibiting a high drying efficiency through the radiant heat by far-infrared with the convective heat caused by the circulation of warm air. It is for the purpose of providing.

Drying washing machine provided to achieve the above object is a washing unit consisting of a water tank and a washing tank rotatably embedded in the water tank, a drive unit consisting of a drive motor for rotating operation of the washing tank, and installed above the washing tank to generate heat And a far infrared heater which performs a far infrared ray emission action, a reflection shade which is installed above the far infrared heater and concentrates the far infrared rays emitted to the washing tank side, and a blower fan installed at one side of the far infrared heater to blow heated air into the washing tank. Including the device.

Here, the far-infrared heater is composed of a bulb coated with a far-infrared film and a heating wire configured in the bulb, so that the far-infrared radiation is emitted from the far-infrared film by the heating action of the heating wire.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying FIG. 2, and the same reference numerals will be given to the same parts as the prior art configurations of the present invention.

First, the combined dry washing machine according to the embodiment of the present invention, as shown in the figure, a washing unit consisting of a reservoir 12 and a washing tank 14 rotatably embedded in the reservoir 12, and the rotary operation of the washing tank It consists of a drive unit consisting of a drive motor 20 and the like, and a drying device for drying the laundry.

Here, the drying apparatus is installed above the washing tank 14, the far-infrared heater 40, which performs heat generation and far-infrared ray emitting action, and the far-infrared ray mounted and released above the far-infrared heater 40 to the washing tank 14 side. The reflection shade 42 to focus and the blowing fan 44 is installed on one side of the far infrared heater 40 to blow the heated air into the washing tank 12, the far infrared heater 40 is the surface of the far infrared film A coated bulb 401, and a heating wire 402 formed in the bulb 401, the blowing fan 44 is composed of a centrifugal fan.

According to the embodiment of the present invention as described above, when the dehydration stroke is finished, and the drying stroke starts, first, the air around the bulb 401 is heated by the heating action of the heating wire 402, the heated air is blown The blowing air is blown into the washing tank 14 by the action of the fan 44 to circulate the warm air into the washing tank 14. Therefore, the laundry is dried by the convective heat caused by the circulation of the warm air.

At the same time, the far infrared rays are emitted from the far-infrared film on the surface of the bulb 401 by the exothermic action of the heating wire 402, and the emitted far-infrared rays are concentrated downward by the reflecting shade 42 and injected into the washing tank 14, thereby radiating heat by far infrared rays. Due to this, the moisture of the laundry is heated and evaporated.

Therefore, according to an embodiment of the present invention, not only the laundry is dried more quickly by the so-called double heating action through the combination of convective heat caused by circulation of warm air and radiant heat caused by far infrared rays, but also due to the strong penetration characteristics of far infrared rays, The laundry is placed and heated to even drying.

According to the drying combined washing machine according to the present invention as described above, because the structure of the far-infrared heater constituting the drying apparatus, the drying operation of the laundry is performed by a dual heating method in which convective heat by simple heat generation and radiant heat by far-infrared radiation are combined. There is an advantage that a quick and even drying effect can be obtained.
