It maintains the internal temperature of high temperature, and the water sprayed through the nozzle during the washing and rinsing is also high temperature. A heating device is provided to heat the fresh water using this water to wash the dishes using waste heat. To a dishwasher.

In general, restaurants and restaurants use a large number of commercial dishwashers to wash a large number of dishes, and when installing the commercial dishwasher in a kitchen, the main body of the dishwasher is disposed between a washing bowl and a drying rack, which also serve as a bulge tank. The washing line is installed so that it can be placed.

In other words, the dishes to be washed are first washed in the washing table, and the washed dishes are placed in a rack at the washing table and then moved to the washing room of the dishwasher, and the dishes in the washing room are finished after washing / rinsing is completed. The washing table, the washing body and the drying table are installed in one washing line so as to be transferred to the drying rack installed on one side of the washing machine and dried.

Here, when looking at the structure and function of the commercial dishwasher Figure 1 is a perspective view showing a conventional general commercial dishwasher, Figure 2 is a view schematically showing the internal structure of a conventional dishwasher, Figure 3 is a conventional dishwasher It is a perspective view which shows the structure which hot water can be supplied.

As shown in the drawing, the dishwasher is a pair of upper / lower washing nozzles 30a and 30b and upper / lower portions at the center of the bottom surface and the upper surface of the washing chamber 11, which are mostly opened by the upper lifting cover 20. The rinse nozzles 50a and 50b are rotatably installed, respectively, and the upper and lower washing nozzles 30a and 30b spray the washing water toward the dishes in the rack placed in the center of the washing chamber 11 to perform a washing step. The upper and lower rinse nozzles 50a and 50b are configured to perform a rinsing step by spraying rinsing water toward the washed dishes.

In addition, the washing water tank 40 and the rinsing water tank 60 are installed in the washer body 10 under the washing chamber 11, and the upper and lower washing nozzles are pumped by pumping the washing water in the washing water tank 40. Operation of the rinsing motor 61 and the dishwasher to pump the washing motor 41 and the rinsing water of the rinsing water tank 60 to the upper and lower rinsing nozzles 50a and 50b. A circuit board (not shown in the figure) or the like of the control unit for controlling the program is provided.

In addition, hot water supplied through the water supply line 71 after being preheated to about 40 to 45 ° C. in a hot water booster or an instant water heater (not shown in the drawing) is provided to the distributor 70 in which each flow path is controlled to be opened and closed by a solenoid valve. It is comprised so that the rinsing water tank 60 and the washing water tank 40 may be filled one by one.

In addition, the rinsing water tank 60 has a structure in which hot water is automatically supplied when the water level is lowered by a valve operated as a water level sensor, and a separate heater 62 is installed in the rinsing water tank 60 to rinse. By heating the water with hot water of approximately 90 ℃ or more so as to achieve a drying effect with the sterilization effect of the rinsed dishes when the rinsing step is performed.

In addition, although not shown in the drawing, a predetermined amount of detergent is introduced into the washing water tank 40 by a separate detergent motor, and a predetermined amount of rinse is introduced into the rinsing water tank 60 by a separate rinse motor. It is structured.

Most of the operation parts of the commercial dishwasher put the rack containing the dishware in the state in which the power on / off switch is turned on in the washing chamber 11, and the lift lid 20 is closed to close the 40 to 45 of the washing water tank 40. ℃ to the washing step is sprayed to the upper and lower washing nozzles (30a, 30b), and when the washing step is completed, hot water of 80 ° C or more in the rinsing water tank 60 to the upper and lower rinsing nozzles (50a) (50b) A rinsing step that is sprayed to rinse and sterilize is programmed to be performed.

Here, the water in the rinsing water tank 60 is heated to 90 ° C. by the heater 62 after receiving the water of the reduced water level by performing the rinsing step once from the instantaneous water heater, and the high temperature (80 ° C. used in the rinsing step). The rinsing water of the above) is lowered to about 60 ~ 70 ℃ during the process of rinsing the dishes, but can be said to be higher than the wash water temperature (40 ~ 45 ℃) in the wash water tank (40).

Therefore, since the use water changed to 60 ~ 70 ℃ during the rinsing step is mostly introduced into the wash water tank 40, the temperature of the wash water in the wash water tank 40 gradually increases while operating the dishwasher due to the temperature of the water used As the water is raised, the washing water in the washing water tank 40 has a structure in which a part of the washing water is discharged through the overflow hole whenever the water is used.

On the other hand, conventionally used high temperature water used through the rinsing step is introduced into the wash water tank 40 and is discharged through the overflow hole, this time using the temperature of the discarded waste water rinsing water tank 60 In order to increase the temperature of the water flowing into the rinsing water in the rinsing water tank (60) to heat the heater 62 to heat the heater 62 so as to reduce the heating time has already been proposed, double application In the case of "waste heat energy recycling device for dishwasher" filed under No. 10-2003-0009241 and registered under No. 10-0462171, a method of recycling waste heat energy contained in waste washing water discarded by using a double wrinkled pipe has also been proposed. However, since the double pleated pipe is exposed to the outside and is not effective in terms of thermal efficiency management, the heating time of the heater for adjusting the rinsing water to the set temperature is sufficient. There was not no more than a problem.

In addition, a variety of devices and methods for using waste heat when using the dishwasher, the general commercial dishwasher is to perform the washing step, the rinsing step as described above.

That is, the washing water tank and the rinsing water tank are installed inside the washer body at the bottom of the washing chamber, and the washing motor pumping the washing water of the washing water tank and supplying the upper and lower washing nozzles to the rinsing water of the rinsing water tank. A rinsing motor for supplying the upper and lower rinsing nozzles and a circuit board for a control unit for controlling an operation program of the dishwasher are provided.

In addition, the hot water supplied through the water supply line after being preheated to about 42-52 ° C. in the hot water booster or instant water heater is configured to fill the rinsing water tank and the washing water tank in turn by a distributor in which each flow path is controlled by a solenoid valve. Some products are configured so that hot water is supplied directly to the rinsing water tank without using a distributor.

The rinsing water tank has a structure in which hot water is automatically supplied when the water level is lowered by a valve operated as a water level sensor. A separate heater is installed inside the rinsing water tank to heat the rinsing water with hot water of about 80 ° C. or more. As a result, when the rinsing step is performed, a drying effect can be obtained together with a sterilizing effect of the dishes dished.

Most of the operation parts of these commercial dishwashers have a rack containing dishware to be washed with the power on / off switch turned on in the cleaning room, and the lift cover is closed to close the water, and the washing tank has 55 to 60 ° C of water. When the washing step is carried out, and the washing step is completed, hot water of 80 ° C. or higher of the rinsing water tank is sprayed to the upper / lower rinsing nozzles so that the rinsing step of rinsing and sterilizing is performed.

Here, the water in the rinsing water tank is rinsed at a high temperature (more than 80 ~ 90 ℃) used in the rinsing step after receiving the water of the water level reduced by performing the rinsing step once and being supplied from the instant water heater. The temperature is lowered to 60 ~ 70 ℃ during the process of rinsing dishes, but can be said to be higher than the wash water temperature (55 ~ 60 ℃) in the wash water tank.

Therefore, most of the water used at 60 ~ 70 ℃ during the rinsing step flows into the wash water tank, so the temperature of the wash water in the wash water tank gradually increases while the dishwasher is running due to the temperature of the used water. Wash water is used

Each time the water flows in, some parts are drained out through the overflow hole provided in the wash water tank.

The water supplied to the rinsing water tank is preheated by about 42 to 52 ° C. by a hot water booster or an instantaneous water heater, as shown in FIG. 3, and the water supplied to the rinsing water tank and the washing water tank is thus heated. Alternatively, the instantaneous water heater may be supplied, but hot water may be supplied to the dishwasher through a waste heat recovery apparatus using high temperature water discharged from the dishwasher in order to reduce costs and ease of installation due to fuel consumption.

That is, in the conventional waste heat recovery device, the raw water inlet is formed on one side of the enclosure to be connected to the water pipe, and the hot water supply is formed on the other side of the enclosure to be opened and closed by a solenoid valve so as to be connected to the rinsing water tank and the washing water tank of the dishwasher. It is connected to the distributor, and the inside of the housing is connected to the raw water inlet, and the other end is connected to the hot water supply, the raw water pipe is bent irregularly.

In addition, a discharge inlet is formed at one side of the enclosure so that hot water can overflow from the wash water tank of the dishwasher, and a discharge outlet is provided at the other side of the enclosure so that the discharged water entering the discharge inlet can be discharged back to the outside. Formed.

Therefore, the inside of the enclosure is filled with the hot water inflow from the water inlet, the raw water pipe is heated by the water, and the raw water exiting the hot water supply through the raw water pipe through the water inlet is heat-exchanged with the hot water As the hot water is introduced into the rinsing water tank through the distributor, the heating time of the heater for raising the rinsing water of the rinsing water tank to the set temperature can be reduced, thereby reducing the cost of fuel consumption.

However, in the conventional waste heat recovery apparatus as described above, the raw water of the raw water pipe located inside the enclosure is discharged to the drainage outlet as the hot water discharged into the discharge inlet of the enclosure does not stay sufficiently in the interior of the enclosure and is discharged to the discharge outlet immediately. There was a problem that the efficiency of the waste heat recovery device is reduced because the heating time of the heater to increase the rinsing water of the rinsing water tank to the set temperature is not shortened because the raw water is not heated sufficiently without heat exchange.
