Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 to 8.

Referring to FIG. 1, the laundry treatment apparatus 100 forms an exterior and has a cabinet 111 having an upper portion and an upper portion thereof, and is disposed on the upper portion of the cabinet 111 with the laundry (hereinafter referred to as 'fo'). A cabinet cover 112 having a fabric entrance and exit port formed therein, a door 113 for opening and closing the portal entrance and exit, and an outer tub that is suspended inside the cabinet 111 by the support member 117 and cushioned by the damper 118. And an inner tub 115 disposed inside the outer tub 122 and rotating about a vertical axis to accommodate the cloth. Here, the inner tank 115 is provided with a plurality of manual work 115a to allow the wash water to circulate between the outer tank 122 and the inner tank 115, and a pore access hole (h) to allow the fabric to enter and exit the upper tank 122. The outer cover 114 is formed. The bottom of the inner tank 115 is provided with a pulsator 116 to form a rotational flow, the lower side of the outer tank 122, the motor for generating a rotational force for rotating the inner tank 115 and / or the pulsator 116 ( 130 is disposed. In addition, a drain hose 142 and a drain pump 144 are provided to drain the wash water from the outer tub 122.

The top cover 112 is provided with a control panel 124 to receive a command from the user for the overall operation of the laundry treatment machine 100, a detergent that can accommodate the detergent (D) inside the top cover 112 The box 134 and the detergent box 134 are retractably received, and the detergent box housing forming a flow path such that the washing water introduced from the water supply hose 119 is supplied into the inner tank 115 via the detergent box 134 ( 136 is disposed. In the detergent box housing 136, a distribution hole 136h may be formed to distribute the washing water introduced from the water supply hose 118 to the detergent box 134.

Referring to FIG. 2, when a user sets a washing course, a washing time, and the like through the control panel 124, and the operation of the laundry treatment device 100 is started, detergent must be supplied to wash the laundry. Washing water mixed with detergent (hereinafter, 'washing water mixed with detergent' is referred to as 'detergent') via the detergent box 114 is supplied, and at the same time, the injection unit 150 is supplied into the inner tank 115. Spray the wash water. At this time, since the washing water sprayed by the injection unit 150 directly reaches the cloth while spreading wide, the rinsing performance is improved while reducing the amount of washing water.

Referring to FIG. 3, the washing water sprayed by the sprayer 150 is spread out relatively thinly, and is inclinedly sprayed downwardly of the inner tank 115 while being twisted at a predetermined angle. Therefore, the sprayed washing water comes into contact with the inner and bottom surfaces of the inner tank 115. At this time, the upper boundary line (P) of the portion where the sprayed washing water and the inner tank 115 contact is formed by forming an oblique line from the inner surface of the inner tank 115 to the bottom surface, thereby increasing the spray area.

Referring to FIG. 4, while the inner tank 115 is rotated at a high speed during the washing stroke in which the laundry is washed by the detergent water, intermittent dehydration is performed, and the inner tank 115 is caught by the centrifugal force generated while rotating at a high speed. A phenomenon of sticking to the inner surface of the inner tank 115 may occur. Conventional laundry treatment equipment is a method of supplying the wash water toward the bottom of the inner tank and the washing water is filled with water soaking the cloth, so that a large amount of washing water is consumed to rinse the cloth attached to the inner surface of the inner tank And contaminated washing water used for rinsing still remains in the inner tank, which may cause the fabric to be contaminated again. Therefore, the process of draining the contaminated wash water in the inner tank and supplying clean wash water again must be repeated several times, and the amount of wash water consumed is further increased.

In order to solve the problems as described above, the laundry treatment machine 100 according to an embodiment of the present invention, the inner water so that the washing water directly to the cloth (m) on the inner surface and the bottom surface of the inner tank 115, the inner tank The washing water is sprayed toward the inner side and the bottom side of the 115. At this time, it is preferable that the inner tank 115 is rotated so that the washing water is evenly sprayed on the fabric. It is also possible to continuously rotate the inner tank 115 in one direction or rotate alternately in both directions.

On the other hand, the washing water contaminated while rinsing the cloth is discharged to the outer tank 122 through the hand 115a by centrifugal force, and the drainage pump 144 is operated to be drained to the outside through the drainage passage 142. Thus, recontamination of the fabric is prevented.

Referring to FIG. 5, the injection unit 150 may be disposed at a position close to one side of the detergent water supply units 134 and 136 mounted on the top cover 112. To this end, the detergent box housing 136 may be equipped with a bracket 156 for fixing the injection unit 150.

Hereinafter, referring to FIGS. 3 and 6 to 8, the injection unit 150 has a downward flow direction of the washing water passing through the inflow pipe 151 and the inflow pipe 151 forming a passage through which the washing water flows. It may be inclined to include, and may include a diverging portion 152 formed to gradually increase the cross-sectional area of the flow path so that the wash water passing through the inlet pipe 151 is diverged. The diverging part 152 may be formed in an approximately funnel shape so that the flow passage cross-sectional area gradually increases from the inlet end side through which the washing water is introduced through the inlet pipe 151 to the outlet end side through which the washing water is injected.

On the other hand, the injection unit 150 may further include a reinforcing portion 155 for reinforcing the bonding strength when mounted on the tub cover 112. The reinforcement part 155 may be formed of a plate body protruding outward along the outer circumference of the inlet pipe 151. Referring to FIG. 6, the reinforcement part 155 is formed to form a plate body elongated in the horizontal direction.

The injection part 150 is formed symmetrically from left to right around the reference line M, and when viewed from the front as shown in FIG. 6, the reference line M is a predetermined angle θ between the vertical line L and the reference line M. FIG. To achieve this, the angle is aligned with the angle θfh rotated relative to the centerline penetrating the inlet pipe 151 in the longitudinal direction.

Hereinafter, the angle θ is defined as a 'rotation angle'. Since the injection unit 150 is aligned in a state in which the injection unit 150 is rotated at an angle θ with the vertical line L as described above, the washing water that reaches the inner tank 115 is disposed at an inner side surface of the inner tank 115 as illustrated in FIG. 3. Proceed diagonally to form the upper boundary line (P) to the bottom surface. That is, the upper boundary line P is a boundary line formed while the upper boundary surface S of the sprayed washing water meets the inner surface of the inner tank 115. At this time, the upper boundary layer (S) is formed by the washing water is introduced through the inlet pipe 151 is sprayed along the upper surface (152a) of the diverging portion (152).

On the other hand, the upper surface 152a of the diverging portion 152 is formed to form a predetermined angle (V) with the vertical line (L). Hereinafter, the predetermined angle V is defined as the 'tilt angle'. That is, the smaller the inclination angle (V) is the washing water will be sprayed downward. In addition, the smaller the inclination angle (V), the greater the impact the washing water flowing from the inlet pipe 151 receives from the upper surface 152a, the more the washing water collided with the upper surface 152a will be sprayed while spreading widely. will be.

On the other hand, the width of the washing water sprayed by the injection unit 150 is determined by the angle (W in Fig. 6) formed by both side boundaries (w1, w2) forming the width of the flow path formed by the inner surface of the diverging unit 152 All. Hereinafter, the angle W is defined as 'injection width angle'.

Similarly, the thickness of the washing water sprayed by the spraying unit 150 is determined by the angle T formed by both systems t1 and t2 forming the thickness of the flow path formed by the inner surface of the diverging unit 152. Hereinafter, the angle T is defined as the 'injection thickness angle'.

The inlet pipe 151 is formed to decrease the inner diameter toward the outlet end 151b side discharged to the diverging unit 152 from the inlet end 151a side into which the wash water flows. Referring to FIG. 7, the inner diameter of the inlet end 151a is d1, and the inner diameter of the outlet end 151b is represented by d2, where d1> d2 is established. That is, since the diameter of the flow path pipe 151 gradually decreases from the inlet end 151a to the outlet end 151b, the flow rate of the wash water flowing into the diverging part 152 increases and the injection force is improved.

Laundry treatment apparatus 100 according to an embodiment of the present invention is the upper boundary line formed while the washing water and the inner tank 115 is sprayed while the washing water is sprayed toward the inner and bottom surfaces of the inner tank 115 The rotation angle θ, the injection width angle W, the injection thickness angle T and the inclination angle V are determined so as to form an oblique line. In this embodiment, W is larger than T and obtuse, and V and θ are acute.

On the other hand, in order to have a larger amount of washing water sprayed on the inner surface of the inner tank 115, it is preferable to rotate the spraying unit 150 to be mounted on the cabinet cover 112 so that the θ value is larger. In order to spray the washing water thinly in the width direction, it is preferable to form the diverging part 152 so that the T value becomes relatively large compared to the V value.

9 illustrates a situation in which the washing water is sprayed in an empty state of the inner tank 115. 10 illustrates a situation in which the washing water and the washing water are sprayed into the inner tank 115 in which the laundry is saturated.

1, 9, and 10, when the inner tub 115 is empty, the load is applied to the support member 117 and the damper 118 connected to the outer tub 122 at least. In this case, the distance between the injection unit 150 and the upper end of the inner tank 115 becomes l, and the washing water sprayed by the injection unit 150 reaches a height apart from the upper end of the inner tank 115 by h. On the other hand, when the wash water and the laundry are accommodated to the limit capacity that the inner tank 115 can afford, since the support member 117 and the damper 118 are most heavily loaded, the inner tank 115 sags downward. The distance between the injection part 150 and the upper end of the inner tank 115 becomes l '(l <l'), and the sprayed washing water reaches a height apart from the upper end of the inner tank 115 by h '. . (h> h ')

In the laundry treatment apparatus 100 of the present invention, the rotation angle θ, the injection width angle W and the injection thickness angle T of the injection unit 150 are set so that the washing water is sprayed into the inner tank 115 without overflowing the load regardless of the load. desirable.
