  Hereinafter, a washing machine and a deodorizing method thereof according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, a washing machine according to the present invention includes a housing 10 that has an appearance, a door 11 that is openably and closably installed on the front surface of the housing 10 in order to insert a deodorizing object such as clothes, And a driving operation unit 12 provided on the upper side of the door 11 for operating the washing machine.

  A cylindrical drum 20 opened toward the door 11 is provided in the housing 10. The drum 20 is used as a deodorizing tank in the deodorizing process, and has a double structure of a fixed tank 21 and a rotating tank 22. The rotating tank 22 is rotatably installed in the fixed tank 21 and is driven by a drive motor 41 provided on the rear surface of the fixed tank 21. Moreover, the rotation tank 22 is provided with many through-holes 22a in the side surface and the rear surface so as to communicate with the fixed tank 21, and the length direction is provided on the side surface so as to easily lift the internal deodorizing object. Provided with a number of lifters 22b.

  A water supply pipe 44 for supplying water to the inside of the drum 20 is provided in the upper part of the fixed tank 21. One end of the water supply pipe 44 is connected to the rear surface of the housing 10 so that water is supplied from an external water supply source (not shown), and the other end is connected to a detergent box 45 installed on the front side of the housing 10. Connected. In addition, a water supply nozzle 46 for injecting water into the inside of the rotating tub 22 is provided in order to supply water that has passed through the detergent box 45 to the inside of the drum 20. A drainage pipe 42 and a drainage pump 43 for draining water used for washing are provided in the lower part of the fixed tank 21.

  Outside the fixed tank 21, a duct 30 that draws air inside the drum 20 and circulates again inside the drum 20 is provided. The duct 30 is formed vertically on the rear surface of the fixed tank 21, communicates with the lower rear surface of the fixed tank 21, communicates with the upper end of the deodorant duct 31, and extends along the upper part of the fixed tank 21. At the same time, it is divided into an air duct 32 that communicates with the inside of the drum 20 again from the upper front side of the fixed tank 21.

  The deodorizing duct 31 is provided with a deodorizing agent nozzle 31a for injecting a deodorizing agent for removing contaminated odor particles in the air passing through the inside into a mist. A conventional washing machine that provides a drying function includes a condensation duct installed on the rear surface of the fixed tub to condense and remove moisture in hot and humid air flowing from the drum during drying, and the condensation duct. In the washing machine according to the present embodiment, the deodorizing duct 31 and the deodorizing agent nozzle 31a are not separately configured and the conventional condensing duct is provided. And the use of a condensing agent nozzle should be able to perform the deodorizing function without additional components.

  The blower duct 32 includes a blower fan 32 a that generates a fluid force for circulating air inside the drum 20 and the duct 30, and a heater 32 b for heating the air that flows into the drum 20. .

  Hereinafter, the deodorizing method by the washing machine of this invention is demonstrated based on FIG.

  In general, when these odor particles are separated from the object to be deodorized soaked with each odor particle that induces bad odor such as odor of food and drink, the odor particles circulate in the deodorization duct 31 together with the air inside the drum 20. When it is dissolved, it is discharged to the outside of the washing machine together with the deodorant.

  Hereinafter, a method for separating each odor particle soaked in the deodorizing object from the deodorizing object will be described. First, a mechanical impact is applied to the object to be deodorized. That is, when the rotating tank 22 is rotated in a state where the deodorizing object is inserted, the frictional force generated between the deodorizing object and the deodorizing object or between the deodorizing object and the rotating tank 22 and the inside of the rotating tank 22 The odorous molecules are separated from the deodorized object by the impact force generated when the deodorized object that rises and falls in step d. Second, it is a method of applying heat to the object to be deodorized. That is, when the heater 32b is operated to drive the blower fan 32a, hot air heated while passing through the heater 32b is supplied into the drum 20. Thereafter, when the air comes into contact with the object to be deodorized, each particle attached to the object to be deodorized actively moves, so that these particles are separated from the object to be deodorized. The third method is to dissolve and separate the odor particles soaked in the object to be deodorized in water. That is, when a small amount of mist-like water is supplied to the inside of the drum 20 through the water supply nozzle 46, the odor particles adhering to the object to be deodorized are dissolved in the water and then vaporized and separated together with the water. These methods can exhibit further enhanced effects by selectively using any one of them or combining any two or more thereof. Each odor particle that has been stained in the object to be deodorized has different strengths adsorbed on the object to be deodorized depending on the type thereof, and therefore, it is preferable to use the above methods in appropriate combinations depending on the degree of adsorption.

  Each of the odor particles separated by these methods is in a state of floating inside the drum 20, but these odor particles should be discharged to the outside of the drum 20 so as not to adhere to the object to be deodorized again.

  For this reason, when the blower fan 32 a operates, the air inside the drum 20 including each odor particle circulates in the duct 30. At this time, when the deodorizer nozzle 31a is operated to inject the deodorant into the deodorization duct 31, the air rising along the deodorization duct 31 comes to rub while being mixed with the deodorant. Each odor particle floating inside is dissolved in a deodorizer and removed. When using a known liquid deodorant as this deodorizer, a separate device for supplying the deodorizer to the deodorizer nozzle 31a is required. In this embodiment, water is used as the deodorizer. Therefore, a separate device is not necessary, and water supplied by a normal washing machine water supply device may be injected through the deodorizer nozzle 31a. In general, water is a very good solvent. For example, in the case of a gas such as ammonia, 53.5 g is dissolved per 100 g of water at room temperature. Each odor particle in the air is dissolved in water and removed as described above. Next, the water in which each odor particle is dissolved is discharged to the outside of the washing machine by the drain pipe 42 and the drain pump 43.

  In the deodorization process, the operation of separating odor particles and the operation of removing the separated odor particles with a deodorizer are described sequentially for convenience, but these operations are performed substantially simultaneously. .
