Definitions
- the present invention relates to a structure of a circulating water storage device in a laundry processor, and in particular, to the design of a water outlet of a water storage device.
- a washing machine using recycled water is available in the prior art.
- a circulating water storage device is disposed in the washing machine.
- An upstream of the water storage device is connected to a laundry processing barrel of the washing machine through a water pump, and a downstream is connected to a water device such as a laundry processing barrel or a condenser, thereby utilizing water used in the previous operation of the washing machine for a second time or for several times, and achieving the goal of saving water resources.
- a water outlet of the water storage device is generally located at the bottom, water flow is greatly affected by the water level in the water storage device. When the water level is high, the water pressure near the water outlet is high and the water flow is great. As water flows out, the water level declines, the water pressure near the water outlet is reduced, and the water flow becomes smaller.
- the unstable flow is adverse to reasonable utilization of water in some cases.
- secondary water for condensation in the drying process; in this case, the water outlet of the water storage device is connected to a condensation passage to cool drying air passing through the condensation passage, so that water vapor carried in the drying air is cooled and condensed and separated from the air.
- the excessive supply of the secondary water for condensation causes an unnecessary waste, and the insufficient supply fails to produce an expected drying effect.
- the water storage device in the prior art is used to provide cooling water to the condensation passage, the cooling water flow inevitably becomes smaller, thereby failing to achieve an ideal utilizat- tion effect.
- An objective of the present invention is to stabilize the flow at a water outlet of a circulating water storage device. Accordingly, the present invention provides a solution as defined in the independent claim attached. Preferred embodiments of the invention are subjects of dependent claims, the subsequent disclosure and the drawing attached. Therefore the invention adopts the following technical solution:
- a laundry processor by use of circulating water is provided with a water storage device for containing the circulating water.
- the water storage device has a water outlet located at the bottom of the water storage device.
- the water outlet includes a movable wall, and the movable wall is disposed into a drainage passage tending to compress the water outlet under the effect of water pressure.
- the movable wall is made of an elastic material.
- the elastic material may be rubber.
- the laundry processor further includes a condensation passage. The water outlet of the water storage device is connected to the condensation passage, to supply cooling water to the condensation passage.
- the laundry processor further includes a laundry processing barrel.
- An upstream of the water storage device is connected to the laundry processing barrel through a water pump.
- FIG. 1 is a composition block diagram of a washing and drying machine
- FIG. 2 is a cross-section diagram of a first embodiment of a water outlet of a water storage device
- FIG. 3A is a front view of a second embodiment of a water outlet of a water storage device
- FIG. 3B is a cross-section diagram along A-A of second embodiment of a water outlet of a water storage device.
- a laundry processor 1 as embodied in a washing and drying machine 1 includes a laundry processing barrel or tub 2, and the bottom of the laundry processing barrel 2 is connected to a water inlet 5 of a water storage device 4 through a water pump 3.
- Water outlets 6 and 8 located at the bottom of the water storage device 4 are connected to a condensation passage 7, to supply cooling water to the condensation passage 7, so as to cool drying air passing through the condensation passage 7.
- the condensation passage 7 is connected to the laundry processing barrel 2.
- hot and damp drying air carrying moisture enters from the bottom of the condensation passage 7, and after cooled by the cool- ing water, the moisture in the drying air is condensed and separated. The rest of relatively dry air re-enters the laundry processing barrel 2 from the top of the condensation passage 7, and enters next circulation.
- a first embodiment of the water outlet 6 of the water storage device 4 includes a drainage passage 61.
- the drainage passage 61 is provided with a fixed wall 62 made of a hard material and an elastic wall 63 made of an elastic material.
- the elastic wall 63 tends to compress the drainage passage 61 under the effect of water pressure in the water storage device 4, and the compressed degree of the drainage passage 61 increases and decreases as the water pressure increases and decreases. Therefore, when more water is stored in the water storage device 4, a greater water pressure acting force is applied on the elastic wall 63, and the drainage passage 61 becomes narrower; as the water level in the water storage device 4 declines gradually, the water pressure acting force on the elastic wall 63 decreases gradually, and the drainage pas- sage 61 becomes wider gradually.
- a first embodiment of a water outlet 8 of a water storage device 4 includes a drainage passage 81.
- a wall of the drainage passage 81 includes several elastic strips 82 concentrated inwardly to form a taper. The top of the taper is oriented toward the inside of the water storage device 4. Therefore, under the effect of the pressure of water 83, the elastic strips 82 are concentrated inwardly, and compress the drainage passage 81 . Compression of the drainage passage 81 increases and decreases as the water pressure increases or decreases.
