In general, the automatic washing machine for door type shops rinses with warm water (about 10 seconds) after the first washing process (about 1 minute) .The heater is installed in one rinse water tank for about 10 seconds per minute. Rinse and sterilize utensils with enough hot water.
This conventional method requires a large amount of water to be heated in a large rinse water tank.

Because of the large heat loss, the temperature difference in the rinsing water tank is large due to convection of water.In general, the rinsing pump is placed on the floor to lower the temperature of the lower layer of the lower layer than the upper layer in the rinsing tank. It was true that it has been used.

     As described above, the present invention for achieving the above object supplied from the automatic dishwasher is a water tank of the lower portion by using a water tank equipped with the upper and lower double hot water supplied to the rinsing water tank of the automatic dishwasher And install a hot water flow guide partition inside of it to create a meandering hot water flow guide, and the hot water flows along it, and a heater is installed inside the hot water flow guide, When the rinse pump operates for about 10 seconds, the check valve installed at the top is closed to prevent the inflow of low temperature water and only the water heated to the high temperature of the lower tank is used as the rinse water for dish washing. The amount of water drained by the rinse pump is replenished through the hot water inlet pipe, which is then cleaned and cleaned by the heater inside. It is heated for a time (about 1 minute) that is going to be to achieve the above object to be able to rinse at a high temperature.

Hereinafter, the configuration and operation of the present invention to be described in detail by the accompanying drawings.
1 is a side view showing different rinsing water tanks and check valve upper hot water inlet, FIG. 2 is a view showing the flow of water when the rinsing water pump is installed and operated, and FIG. 3 is inside the secondary rinsing water tank. Figure 4 is a perspective view of the hot water flow induction partition and the heater is installed from above the secondary rinsing water tank.
In FIG. 1, a primary rinsing water tank 1 is installed on the secondary rinsing water tank 2, and a heater 6 is installed in the secondary rinsing water tank 2, between both tanks 1 and 2. Block plate (3) is installed to block the hot water flow induction starting point diagram 4 (11) to prevent the hot water inflow pipe (4) is lowered below the block plate (3) to prevent bubbles and hot water coming out A check valve (5) is installed above the rinsing water pump (10) connector side block plate (3) to allow air bubbles and high temperature rinsing water to flow out only, and when the automatic dishwasher is not operated, it is heated by heater as shown in FIG. The condensed water is circulated to the primary rinsing water tank 1 and the secondary rinsing water tank 2 by natural convection.
Inside the secondary rinsing water tank (2) induce hot water flow into the hot water flow induction partitions (7a), (7b), (7c) of several, single-sided """as shown in Figures 3 and 4 The furnace is formed, and the heater 6 is provided between them.

In general, the time required for the first wash of a door type dishwasher is about 1 minute, and the rinse wash time is about 10 seconds after the first wash. "
When the rinsing water pump (10) is operated for about 10 seconds when the rinsing and washing is finished, the check valve (5) is closed at the same time, blocking the inflow of low temperature water and as much as the amount of water drained from the second rinsing water tank (2). To increase the length of the hot water inlet pipe 4 in order to supply water of the upper layer having a relatively higher temperature than the lower layer in the first rinsing water tank 1.
The water coming down the hot water inlet pipe (4) is introduced along the hot water flow path """as shown in FIGS. 3 and 4. ) Is heated and at the same time the external hot water is supplemented to the height of the water level sensor (9) of the primary rinsing water tank (1) through the external hot water inlet (8).

When the rinsing water pump 10 is operated, the check valve 5 is closed at the same time to block the inflow of low temperature water, and the hot water in the secondary rinsing water tank 2 is supplied with hot water flow induction partitions 7a, 7b, and ( 7c) flows toward the outlet with the rinsing water pump 10 sequentially along the hot water flow induction path formed by the water, and the amount of water sold by the rinsing water pump 10 operates by operating the size of the secondary rinsing water tank 2. 2 times larger than the hot water flowing into the secondary rinsing water tank (2) through the hot water inlet pipe (4) is heated sequentially along the hot water flow induction, even higher temperature in front of the final rinse water pump (10) The rinsing water is heated. In addition, when the operation of the rinsing water pump 10 stops, the check valve 5 located on the upper part of the second rinsing water tank 2 is opened to allow air bubbles to discharge due to the heating of the heater 6 and natural convection of the hot water. In addition, the temperature of the water inside the first rinsing water tank (1) and the upper layer was increased.
In describing the present invention, three hot water flow guide partitions (7a), (7b), (7c) are shown on the attached surface, but according to the installation conditions, the rinse water temperature can be increased by installing more hot water flow guide partitions. It is not intended to be.
