Abstract

PROBLEM TO BE SOLVED: To safely discharge washing water. SOLUTION: In a dish washing drier provided with a water supply route 51 having a water supply valve 41 and a water discharge route 52 having a water discharge pump 50, where at least one of the water supply route 51 or the water discharge route 52 is incorporated in the other route, washing water is maintained at about 50 to 60 deg.C during a washing process, and heated to about 70 deg.C during a last rinsing process. Thus, the washing water is discharged to the water discharge route 52 in its high temperature state after the washing or in the last rinsing process. But at this time, since a part of the water supply route 51 is incorporated in the water discharge route 52, the washing water sent into the water discharge route 52 is cooled by washing water existing in the water supply route 51, its temperature becomes lower than a specified temperature during the washing or last rinsing process, and thus the washing water is discharged without giving any damage to the sink of a kitchen or a drain pipe.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher for safely discharging washing water.

[0002]

2. Description of the Related Art A conventional dishwasher will be described below.

As shown in FIG. 8, a conventional dishwasher dries a tableware basket 8 containing tableware 7 and the like in a predetermined place, and then starts operation by adding a detergent.

[0004] When the operation is started, the water supply valve 2 is first operated to supply a predetermined amount of washing water 3 from the water supply path 12 to the washing tank 1.
To supply. Then, the cleaning pump 4 pressurizes the cleaning water 3 and injects the cleaning water 3 from the injection holes 6 provided in the nozzle 5 together with the detergent. Thus, the cleaning step is performed. In this cleaning step, the heating element 9 provided in the cleaning tank 1 is energized to heat the cleaning water 3 to a predetermined cleaning temperature.

After a cleaning step for a predetermined time, the tableware 7
The washing water 3 containing the dirt washed off from the apparatus is discharged from the washing tank 1 by the drain pump 10 through the drain passage 13 to the outside of the machine. Subsequently, the cleaning water 3 is newly supplied to the nozzle 5.
Is sprayed again from the injection hole 6 provided in the container, and a step of rinsing the dishware 7 and the like contaminated with detergent or garbage (the food adhered to the ware 7 as dirt is called garbage) is executed. .
When the rinsing step is completed, the washing water 3 is discharged again to the outside of the machine. This rinsing step is repeated several times continuously.

[0006] In the washing and rinsing steps, the residue is collected in a filter 11 provided in the washing tank 1. After a predetermined number of rinsing steps, the drying step starts. In this step, the air blowing means 14 operates, and air outside the machine is sent into the cleaning tank 1 via the air blowing path 15. The sent air dries the tableware 7 and the like, and is exhausted outside from the exhaust port 16. After the drying step, the operation of the dishwasher is completed.

[0007]

However, the dishwasher having the conventional structure has the following problems. In the conventional dishwasher / dryer, as shown in FIG. 9, in the washing step, the washing water 3 is at a predetermined washing temperature of 50-60.
The temperature is controlled to be maintained at a high temperature of ℃, and after the washing process is completed, the water is discharged from the drainage path 13 to the outside of the machine by the drainage pump 10. In the final rinsing step, the washing water 3 is heated to a high temperature of about 70 ° C., which is a predetermined rinsing temperature, and then discharged outside the machine. Therefore, after the completion of the cleaning step, the washing water 3 at 50 to 60 ° C. is discharged out of the machine through the drainage path 13, and in the final rinsing step, the washing water 3 at about 70 ° C. is discharged outside the machine. Therefore, the sink and drain pipe of the kitchen from which the washing water 3 is discharged need to be designed to withstand the high-temperature washing water 3, and there is a problem that a low-cost configuration cannot be achieved.

When high-temperature washing water 3 heated in the washing and rinsing steps is supplied to a sink formed of a material such as stainless steel, the sink undergoes a rapid temperature change from room temperature to high temperature. As a result, the sink expands and becomes distorted. Therefore, there is also a problem that noise is generated from the sink when the sink expands or when the sink contracts to return to the original shape after the expansion.

Further, in order to surely kill bacteria such as O-157 and clean the tableware 7 in a sanitary manner, the temperature of the washing water 3 in the final rinsing step is made higher than 70 ° C. to clean the tableware 7 and the like. A dishwasher / dryer is also provided. Therefore, there is also a problem that a sink or a drain pipe from which the cleaning water 3 is discharged needs to be designed to withstand the higher-temperature cleaning water 3.

SUMMARY OF THE INVENTION In view of the above problems, it is a first object of the present invention to discharge washing water without damaging a kitchen sink or a drain pipe.

It is a second object of the present invention to make the periphery of the dishwasher simpler.

It is a third object of the present invention to discharge washing water without reducing the drying performance of tableware and reducing damage to kitchen sinks and drain pipes.

It is a fourth object of the present invention to discharge washing water with less damage to a kitchen sink and a drain pipe, and to more efficiently dry tableware.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is directed to a water supply path having a washing tank, a tableware for storing dishes and the like, a water supply valve for supplying washing water, A washing pump for pressurizing the washing water, a nozzle having an injection hole for injecting the washing water, a drainage path having a drainage pump for discharging the washing water, and a blowing path having a blowing means for blowing air, The water supply path is configured such that at least a part of the water supply path is provided in the drainage path, so that the dishwasher and the dishwasher wash the dishes in accordance with a predetermined operation program. To maintain
In the final rinsing step, heating is performed by a heating element until the temperature reaches about 70 ° C.

[0017] Therefore, the washing water is discharged to the drainage channel by the drainage pump in a high temperature state after the completion of the cleaning process or the final rinsing process. At this time, a part of the water supply channel is provided in the drainage channel. Since the low-temperature washing water newly supplied to the washing tank is present in the water supply path, the washing water sent to the drainage path is cooled by the washing water existing in the water supply path, and is provided in a predetermined manner in the washing or final rinsing step. It becomes lower than the temperature of. Therefore, the washing water can be discharged without damaging the kitchen sink and the drain pipe.

Further, since the low-temperature washing water newly supplied to the washing tank is heated by the high-temperature washing water discharged from the drain passage, the washing water having a higher temperature than before can be supplied to the washing tank. This has the effect that the time for heating the cleaning water to a predetermined temperature in the cleaning or rinsing step can be reduced, and the energy required for the heating element to heat the cleaning water can be reduced.

According to a second aspect of the present invention, in addition to the first aspect, a water supply path or a drainage path is provided at least at a portion connecting the dishwasher main body and the water tap. By adopting a configuration that is installed in the channel, the water supply channel is entirely installed in the drainage channel, which connects the dishwasher and the faucet or branch faucet. Alternatively, a path including a water supply path and a drainage path can be provided between the tap and the branch tap, and a drainage path alone can be provided between the tap or branch tap and the kitchen sink. Only one path can be output from the dryer body.

Therefore, the number of paths output from the dishwasher body can be reduced to one without providing two water supply paths and drainage paths as in the related art, so that the peripheral portion and installation of the dishwasher can be simplified. It has the effect that it can be made into a thing of a simple structure.

According to a third aspect of the present invention, in addition to the first or second aspect, the water supply path is connected so as to directly supply cleaning water to a substantially bottom portion of the cleaning tank, and is provided with a drain pump. By adopting a configuration in which new washing water is supplied before the washing water is discharged, in the washing or rinsing step, the washing water is heated to a predetermined temperature in each step. Before the water is drained out of the machine via the drainage path by the drainage pump, the water supply valve is energized to supply new low-temperature washing water directly from the water supply path directly to the approximate bottom of the washing tank. The discharged washing water can be changed from high temperature to low temperature.

When the washing water is discharged to the outside of the machine after the temperature becomes low, low-temperature washing water is discharged to the kitchen sink and the drain pipe. Damage can be reliably and further reduced.

In addition, since the water supply path is connected to the substantially bottom of the washing tank, low-temperature washing water does not come into contact with the high-temperature dishware at the end of the final rinsing step, so that the high-temperature dishware is cooled. There is an effect that the new low-temperature washing water can be supplied to the high-temperature washing water and cooled without the need.

According to a fourth aspect of the present invention, in addition to any one of the first to third aspects, an auxiliary tank is provided at a portion of the drainage path connecting the washing tank and the drainage pump. The auxiliary tank is provided with an air heating unit that conducts heat conduction or heat transfer with the air supply path. When the washing and rinsing steps are completed, the on-off valve opens, and the washing water present in the washing tank is removed from the auxiliary tank. Sent to The cleaning water sent to the auxiliary tank is supplied to a drainage path by a drainage pump, cooled by low-temperature cleaning water existing in a water supply path, and discharged outside the machine. When the final rinsing step is completed, the on-off valve opens and the washing water is sent to the auxiliary tank.

At this time, the drain pump does not operate,
The process proceeds to the drying step while the high-temperature washing water is present in the auxiliary tank, and the washing water existing in the auxiliary tank is discharged by the drain pump during or after the drying step. Therefore, since the high-temperature washing water is present in the auxiliary tank even during the drying process, after the drying process is started, the outside air that is blown into the blowing route by the blowing means is supplied to the blowing route via the air heating unit. The washing water present in the auxiliary tank provided therein is cooled and simultaneously heated by the washing water. Therefore, the washing water discharged after the end of the final rinsing step is cooled not only by the low-temperature washing water existing in the water supply path but also by the outside air passing through the blowing path during the drying step. Therefore, the high-temperature washing water discharged in the final rinsing step can be discharged to the outside at a lower temperature.

Further, since the air outside the machine is heated by the cleaning water present in the auxiliary tank via the aeration heat section, higher-temperature air can be supplied into the cleaning tank, and the air can be more efficiently supplied. It has the effect that dishes can be dried.
