Description

[Detailed description of the invention]

The present invention relates to a convenient dehydrating washing machine that makes it easy to use powdered soap. Powdered soap is difficult to dissolve in low-temperature water, so if you put powdered soap directly into the inner tank of a dehydrating washing machine and wash it without it completely dissolving, the soap powder will remain attached to the outside of the inner tank. As a result, there was a risk that mold and the like would grow, which would re-adhere to the laundry and contaminate the items to be washed. Therefore, in the past, soap powder had to be thoroughly dissolved in hot water before being used in a dehydrating washing machine, making it difficult to use soap powder. The present invention was provided for the purpose of solving such conventional problems. Hereinafter, one embodiment of the present invention will be described based on the drawings. In Figs. 1 and 2, 1 is the washing machine main body, 2 is a dehydration receiver installed in the washing machine main body 1, and 3 is a washing machine and dehydrator. The inner tank serves as a water tank, and is rotatably installed inside the dehydration receiving cylinder 2. The inner tank 3 has a pulsator 4 in the center of the lower part, a large number of dehydration holes 5 in the peripheral wall, and a dehydration hole in the upper opening edge. A balancer 6 is provided in each case to reduce the vibrations. A driving motor 7 is capable of driving the pulsator 4 and the inner tank 3 via a belt transmission mechanism 8 and a clutch mechanism 9. The dewatering receiver 2 is suspended from the washing machine main body 1 by a suspension 10 and supported in a vibration-proof manner, and a drain hose 12 is connected to the dewatering receiver 2 via a drain electromagnetic valve 11. At the top of the washing machine body 1, there is provided an upper part 14 to which a lid 13 is attached so that it can be opened and closed, and a time switch 15 for electrically controlling a series of washing processes and a water supply for hot water are provided in a part of the upper part 14. A panel section 21 equipped with a solenoid valve 16, a water supply solenoid valve 17 exclusively for water, a pressure switch 18 that detects the water level in the inner tank 3, a lid safety switch 19 that is linked to the opening and closing of the lid 13, a changeover switch 20 that switches between hot and cold water, etc. will be provided. time switch 1
5 has therein _a timer motor 22, cam switches _T1 to _T5 which operate in accordance with the program shown in FIG. 23 is the power supply, 2
4 is a capacitor. Note that the changeover switch 20 operates as a contact point as shown in the following table.

[Table] However, W indicates hot water, and C indicates cold water. In the above configuration, when the contact S ₁ of the changeover switch 20 is turned on when water is supplied for washing, the water is supplied via the power supply 23 → cam switch T ₁ → NC of the pressure switch 18 → a of the cam switch T ₃ to the water-only water supply solenoid valve 17. is energized, and the power supply 23
→ Cam switch T ₁ → NC of pressure switch 18 → a of cam switch T ₃ → a of cam switch T ₂ → contact S of changeover switch 20 The water supply solenoid valve 16 exclusively for hot water is energized via the contact S ₁ , and the hot water is mixed with water. Water is supplied into the inner tank 3. Contact S ₁ of changeover switch 20 is OFF
If it is, only the water supply electromagnetic valve 17 exclusively for water is energized, and only water is supplied into the inner tank 3. The reason why only the water supply electromagnetic valve 16 for hot water was not operated is because water at a very high temperature is not required to dissolve powdered soap. When a specified amount of water is supplied into the inner tank 3, the pressure switch 18 is switched from NC to NO, and the drive motor 7 and timer motor 22 are energized, and the drive motor is switched on according to the reversing cam switch _T6 . The pulsator 7 is reversed at regular intervals, and washing is performed while the pulsator 4 is rotated forward and backward. During draining, the drain solenoid valve 11 is energized via the power supply 22 → cam switch T ₁ → pressure switch 18 NO → cam switch T ₄ a → cam switch T ₅ b, and the water to be washed in the dewatering receiver 2 is drained from the drain hose 12. The water is drained outside the machine. When rinsing, as well as when washing, it is possible to supply both hot water and cold water when contact S ₂ of the changeover switch 20 is ON, and only water when contact S ₂ is OFF.
By setting the contacts S ₁ and S ₂ , it is possible to switch in three ways: washing and rinsing with lukewarm water, washing with lukewarm water and rinsing with water, and washing and rinsing with water only. It is very convenient and effective to use. A short-circuit switch 25 that short-circuits the water supply solenoid valve 16 exclusively for hot water and the drive motor 7 so that they form a parallel circuit.
If the short-circuiting switch 25 is configured to short-circuit only when the button is pressed, powdered soap can be added and the driving motor 7 can be energized even while hot water is being poured, and the pulsator 4 can be rotated. Further, by turning off the changeover switch 20 after the powdered soap has melted, unnecessary hot water can be saved, and a dehydrating washing machine that is highly desirable from the standpoint of energy saving can be obtained. According to the present invention, when washing and rinsing, it is possible to appropriately select and supply hot water and water using the time switch and changeover switch, and therefore powder soap dissolves well in the inner tank, so powder soap can be used. has become extremely versatile, and its practical value is extremely large. Further, according to the present invention, the water supply solenoid valve and the washer drive motor of the drive mechanism are connected in parallel only when the button is pressed, so that the drive motor is operated only when water is supplied in the washing process, Equipped with a short-circuit switch to stir the liquid in the inner tank, it is possible to reliably dissolve detergent such as powdered soap before the washing operation, and it also prevents accidental short circuits when there is no liquid in the inner tank. Even if the switch button is pressed, the drive motor does not operate, making it possible to reliably prevent clothing from being damaged.
