Description of the Related Art Conventionally, a dishwasher is a pressure-feeding pump for washing while rotating a nozzle for injecting washing water into a washing tank in reaction to the injection, and constantly passes through a filter for adsorbing food debris. While circulating the water in the washing tank, warm the washing water with the heater in the washing tank, further attach the device to drop after washing the detergent preliminarily, perform drainage and water supply for every rinse,
After the rinsing was completed, the heater fan was separately mounted for drying. [0003] In the prior art, the filter is clogged with food debris at the time of pre-washing, and a desired water pressure cannot be obtained at the time of main washing and rinsing. The dishes were washed with the passed sewage, and there was a problem that the washing performance was lacking. SUMMARY OF THE INVENTION The present invention provides a preliminary washing method for washing dishes in a washing container with water, and a tableware for performing a full washing with washing water containing a detergent after the preliminary washing is completed. In the washing machine, a water channel provided with a filter is used at the time of preliminary washing, a water channel that does not pass through the filter is used at the time of main washing, and a lid of a box body in which a detergent is put in a valve body that switches each of the water channels. The lid of the box is opened in conjunction with the switching between the water channel used for pre-washing and the water channel used for main washing.Food debris dropped from tableware by pre-washing is filtered out. After the removal, the main washing and rinsing are performed while circulating the washing water in a water channel that does not pass through the filter, so that it is possible to prevent a decrease in water pressure due to clogging of the filter, and to wash the washing water with food waste. It is possible to prevent soiling and eliminate the need for a special device to drop detergent after pre-washing, with a simple structure and to ensure that detergent is included in washing water at the right time, making the dishwasher lightweight and compact. In addition, the cost can be easily reduced. An embodiment of the present invention will be described below in detail with reference to the drawings. 1 is a sectional view of the entire dishwasher according to the present invention, FIG.
Fig. 3 is a partial explanatory view of the dishwasher, Fig. 3 is a sectional view of the pump, in which (1) is a container lid, (2) is a washing container, and (3).
The main body is formed by a container receiving box, and the rotating shaft projections (4) projecting from the rear ends of the container lid (1) are brought into contact with the receiving portions of the container (2) to open and close the lid (1). The cover (1) is provided with a ventilation hole (29) and a shielding plate (30) with a slight gap at the front surface, so that the washing water does not directly flow out of the ventilation hole (29). A vertical wall (37) is attached near the front surface of the lid (1) and has a lower end opened so as to form a passage for washing water. An odor hole (31) is provided between the front exterior part of the lid (1) and the vertical wall (37) to prevent the odor emitted from the filter (22) for storing food waste from remaining in the container (2). It is because of odor release to the outside air. (9) A pump is a rotation of the impeller (32). When the pump rotates clockwise, the water supply valve (33) is opened and the washing water in the washing tank (15) is opened from the nozzle (7) rotating from the discharge port (5). Is suctioned and sprayed to wash dishes. When the valve is turned counterclockwise, the valve (33) is closed and the drain valve (34) is opened, and the washing tank (15) is opened from the drain pipe (6).
The dirty washing water inside is sucked and discharged. In the course of discharging to the outside, the piston (19)
When the piston (19) is pressed by the water pressure and rises, the bypass lid (16) is pushed open by the push rod (20) of the piston (19) as shown by a dotted line and stopped by the vertical wall (37). The dirty washing water is discharged with the drain port (23) open. The opening and closing of the bi-piper lid (16) is performed by the drainage power of the pump (9). A box lid (17) is attached to a part of the top end of the lid (16), which covers the lid of the detergent charging box (18) attached to the container bottom plate (25) of the container (2). A fan (11) for cooling the motor and a fan (10) for sending out hot air are attached to the shaft of the motor (8) opposite to the pump (9), and the air sucked from the suction port (36) is washed. The cleaning water is warmed by passing through a blower pipe (12), which is a blower passage built in a heater (13) in (15), and hot air is discharged from a blower nozzle (14) into a container lid (1) for cleaning and rinsing. The washing water in the inside is heated, and at the time of drying, the output of the heater (13) is controlled so as to be useful for blast drying at an appropriate temperature. (21) is a drooping valve which hangs down from a filter (22) to a water channel entering the washing tank (15), opens according to the water flow, closes when there is no water flow, and closes the odor from the filter (22) in the container (2). To prevent intrusion. (24) is an electromagnetic valve for opening and closing tap water, and allows tap water to flow into the container (2) through a water pipe (28). (26) is an overflow conduit (2)
7) is a water level sensor which detects the change in resistance between water and air between the two poles, and the reed switch may be operated by a float with a magnet. In this embodiment, the pump (9) attached to one of the two shafts of the drive motor (8) is operated and the drain valve (34) is closed by hydraulic pressure during normal rotation. Then, the water supply valve (33) is opened, and the washing water is sprayed to wash the dishes in the container (2) through the nozzle (7). At this time, the fan (10) attached to the other shaft
Starts blowing air and blows air (12) in the cleaning tank (15).
Heat the washing water and the air in the vessel (2) through the heated heater (13) in the interior. When the pre-washing is completed and the motor (8) is rotated in reverse, the drain valve (34) is opened by water pressure and the water supply valve (33) is closed, and dirty washing water is drained by pump pressure. [0020] When the piston (19) mounted in the drain pipe (6) rises by the water pressure and the bypass lid (16) rises and the bypass water passage is opened, the washing water dropped after spraying and washing the dishes during the preliminary washing is used as a container. Flow through the bottom plate (25) and filter (2
Enter 2), where food waste is absorbed and washed (15)
The water is sucked into the suction port of the pump (9) and the injection is repeated. However, after draining, a bypass channel is formed that does not pass through the filter (22). The food debris accumulates and the suction force of the pump (9) is not weakened. The detergent prepared in advance is supplied to the input box (18) provided at one corner of the container bottom plate (25) during the preliminary washing.
The bypass lid (16) is closed by the box lid (17) of the bypass lid (16), and is set so as to prevent intrusion of washing water. The bypass lid (16) tilts in the opposite direction with force, stops against the vertical wall (37) installed vertically from the container lid (1), and the wall (37) and the container bottom plate (25). Then, the water passage leading to the filter (22) through the through-hole window between the two is cut off, so that a bypass water passage is formed. The drainage port to the outside is opened by the rise of the piston (19), and drainage is performed in that state. When drainage is completed and water supply is started and the water level sensor (27) reaches a specified water level, the solenoid valve (24) closes and water supply stops, and when the pump (9) rotates forward and main washing starts, water is removed. When the water is injected through the nozzle (7) and the injected water hits the tableware and drops, the water enters the detergent and the detergent flows because the bypass lid (16) of the detergent in the input box (18) is open. put out. After the first main washing, the detergent is dissolved in the water heated by the heater (13) to become washing water, so that the washing effect is further enhanced. After the main washing, the rinsing process of drainage, water supply, and drainage is repeated through the bypass water channel. When the washing is completed, the motor (8) is idled with only the fans (11) and (10), and the motor (8) is operated by the fan (10). An appropriate amount of warm air is sent into the container (2) from the blower nozzle (14) through a blower tube (12) with a built-in heater (13) to enter tableware drying, and a ventilation hole (perforated in the ceiling of the container top cover (1)) is formed. Exhaust through 29). As is apparent from the above embodiments, the present invention provides a preliminary washing in which the dishes in the washing container (2) are washed with water, and after the preliminary washing, washing with washing water containing a detergent. In a dishwasher that performs main washing, a water channel provided with a filter (22) is used at the time of preliminary washing, a water channel that does not pass through the filter (22) is used at the time of main washing, and a valve body that switches each of the water channels ( 16) is provided with a lid (17) of a box (18) into which a detergent is to be charged. The lid (17) of the box (18) is interlocked with switching between a water channel used for preliminary washing and a water channel used for main washing. After removing food debris dropped from tableware by a filter (22) with a filter (22), the washing water is circulated through a water channel that does not pass through the filter (22). Wash Since the rinsing is performed, it is possible to prevent a decrease in water pressure due to clogging of the filter (22), to prevent washing water from being stained with food debris, and to eliminate the need for a dedicated device for pre-washing the detergent and dropping it, thereby achieving a simple structure. In addition, the detergent can be surely contained in the washing water at an appropriate timing, and there is a remarkable effect that the dishwasher can be made lightweight and compact and the cost can be easily reduced.
