Definitions

  • the present invention relates to a detergent supply device of a front-loading-type washing machine.
  • a detergent supply device of a front-loading-type washing machine which makes the pressure of washing water to be supplied constant in order to prevent formation of detergent bubbles from increasing due to the pressure of washing water during water supply being high and low, is suggested (for example, refer to PTL 1).
  • Fig. 6 is an exploded perspective view showing the configuration of the front-loading-type washing machine of the related art.
  • the front-loading-type washing machine of the related art is equipped with bottomed cylindrical water tub 11 that is installed inside main body 10 in order to contain washing water, and washing tub 12 that is a bottomed cylindrical rotary drum installed rotatably inside water tub 11.
  • the wall surface of washing tub 12 is formed with a plurality of spin-drying holes 12A.
  • Drive motor 13 that rotates washing tub 12 in normal and reverse directions in order to perform washing, rinsing and spin-drying steps is provided below water tub 11.
  • Water supply device 20 that supplies washing water to the inside of water tub 11, detergent supply device 15 that supplies detergents in a water supply step, and connecting pipe 24 that guides the water, which has passed through detergent supply device 15, to the inside of water tub 11 are provided above water tub 11.
  • Water supply device 20 is constituted by a plurality of water supply valves 21 (21a to 21d) that are connected to an external water supply hose (not shown) and control water supply, and a plurality of water supply pipes 23 (23a to 23d) that connect water supply valves 21 and detergent supply device 15 to each other.
  • Detergent supply device 15 has box-shaped housing 30 that is formed with opening portion 34 having an opening in the front surface thereof, and detergent case 35 that is detachably combined with the inside of housing 30 through opening portion 34 of housing 30.
  • Detergent supply device 15 is provided at an upper front surface portion of main body 10 in order to operate detergent case 35 like a drawer outside main body 10.
  • Fig. 7 is a plan view showing a channel configuration within the detergent case of the detergent supply device of the front-loading-type washing machine.
  • Fig. 7 is a view when the detergent supply device 15 is viewed from above.
  • detergent case 35 of detergent supply device 15 is constituted by at least rinsing agent loading portion water supply channel 45, rinsing agent loading portion water supply portion 43, rinsing agent loading portion 35c, and bleaching agent loading portion 35d.
  • Rinsing agent loading portion water supply channel 45 is formed with pressure regulating holes 45a. In a case where high-pressure washing water flows through rinsing agent loading portion water supply channel 45, a large amount of washing water falls into bleaching agent loading portion 35d through pressure regulating holes 45a. In a case where low-pressure washing water flows, a relatively small amount of washing water falls into bleaching agent loading portion 35d through pressure regulating holes 45a.
  • the pressure of the washing water that reaches rinsing agent loading portion water supply portion 43 is regulated within a predetermined range while passing through rinsing agent loading portion water supply channel 45.
  • the pressure of the washing water jetted to rinsing agent loading portion 35c is also regulated within a predetermined range. This prevents the fullness of detergent bubbles, which are generated by the supply of high-pressure washing water, within detergent case 35. As a result, the washing water containing detergents is smoothly supplied to prevent an occurrence of leak from other than a predetermined channel or the like.
  • detergent supply device 15 of the related art functions effectively, for example, in a case where water supply valve 21c is opened to supply a large amount of washing water into detergent supply device 15 via water supply pipe 23c from the outside of the washing machine at a pressure equal to or higher than a predetermined pressure.
  • the detergent bubbles are filled into detergent case 35 on any other conditions (for example, the detergent bubbles generated within water tub 11 has flowed back to detergent supply device 15)
  • a circulating water stream system which circulates the washing water with a pump to spray the washing water to the laundry, enters the mainstream. Since the circulating water stream system circulates the washing water while taking a lot of air into the washing water, a large amount of detergent bubbles are generated within water tub 11. For this reason, the pressure within water tub 11 is increased by the detergent bubbles, and the generated detergent bubbles flows back into detergent case 35. As a result, the water supply channel from detergent supply device 15 to water tub 11 is blocked, and the washing water flows out of, other than the predetermined channel, during water supply.
  • DE 295 16 998 U1 describes a combined machine for washing and drying of laundry, having a washing tank, a rotatable drum in said washing tank, which is suitable for accommodating the laundry, and which is adapted to rotate at different velocities including the spin speed, an outlet conduit arranged below said washing tank, a circulation circuit for the drying air, which consists of at least a first line for sucking moist air from the interior of the washing tank, a circulation wheel for said drying air, a heating element for said drying air and a line for returning the drying air to said washing tank, wherein said machine is adapted to perform at least a washing cycle comprising at least one rinsing phase following the washing phase, wherein said circulation wheel is switched on for the hot air for a predetermined period of time after said washing phase and before said rinsing phase.
  • JP 2007-068801 A discloses a drum type washing machine with a structure for treating steam generated inside a water tub if the washing machine has a function of heating washing water to a prescribed temperature.
  • a heater is disposed in a washing water heating tub, formed under the water tub in which a rotary drum is stored, for heating washing water.
  • Steam generated inside the water tub when heated is guided into a detergent loading part through an exhaust pipe, and into a water injection lid body for injecting water into a detergent storage chamber, and the steam is cooled in the water injection lid body. Then, the cooled steam is condensed, and water generated by the dew-condensation is fed from the detergent loading part through a water supply pipe and a water supply port to be collected in the water tub 3.
