Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dishwasher equipped with both a washing nozzle and a rinsing nozzle in a washing tank. It was designed to improve safety even though it is equipped with a hot water storage tank.

An embodiment of the present invention will be described below with reference to the attached drawings. In the drawings, 1 is the main body of the dishwasher, 2 is a washing tank disposed inside the main body 1, 3 is a washing circulation pump for circulating washing water, and 4 is a washing circulation pump. A rinse pump for sending rinse water, 5 and 6 are upper and lower cleaning nozzles arranged inside the cleaning tank 2, and 8 is the upper part of the cleaning tank 2 like the cleaning nozzles 5 and 6. and a nozzle for disposing at the bottom, and 9 are nozzle bearings that rotatably support the cleaning nozzles 6.6, and are of the same top and bottom shapes. 1o is a leftover filter provided on the bottom of the cleaning tank 2, 11 is a tableware basket, 12 is a discharge pipe for the cleaning nozzle on the upper side whose one end is connected to the circulation pump 3, and 13 is the inside of the main body 1 and the cleaning tank 2. A rinse pipe is arranged vertically between the outer side of the drain pipe and the lower end is connected to the rinse pump 4. Reference numeral 14 indicates an in-tank connection nozzle (eve) having one end connected to the scrubbing nozzle 7.8 and the other end to the scrubbing pipe 13; In the water heater, 016, which is located before the rinse pump 4, is a water supply valve that supplies water into the water heater 16, 17 is an electric heater that is a heat source for the water heater 16, and 18 is a water boiler. A water supply pipe that guides the rinse water in the vessel 16 to the rinse bonder 4, 19 a sacsidine pipe that guides cleaning water to the cleaning pump 3, and 20 a drainage pump. 23 is the hot water storage tank 2 of the water heater 16.
A water supply pipe 18 is connected to a hot water supply inlet consisting of an L-shaped pipe for supplying rinse water from 6). 24 is a water supply port provided in the hot water storage tank 26 of the water heater 16, and 26 is an overflow pipe provided in the hot water storage tank 26.

And an L-shaped pipe 23 installed in the hot water storage tank 26 of the water heater 16
The suction height B is higher than the top surface height C of the electric heater 17, and the water level height A is higher than the amount of rinsing water used in the - times.
I am trying to make it possible to take it.

Therefore, if the first stage water level increases or if water is not supplied from the water supply port 24, the electric heater 17 will always remain underwater even if the first stage water level drops to water level B. Even if the heater 17 is energized, there will be no abnormal temperature rise until the remaining water evaporates. Further, by turning off the power to the heater 17 through temperature control within the time required for the remaining water to evaporate, dry heating of the electric heater 17 can be prevented and safety can be improved.

As described above, the present invention provides a hot water storage system in which a cleaning nozzle connected to a circulation pump and a rinsing nozzle connected to a rinsing pump are arranged in a cleaning tank, and the hot water storage is located in the main body together with the cleaning tank. A hot water supply port to which a water pipe connected to the rinsing pump is connected is provided in the tank, and this hot water supply port is positioned above the electric heater inserted into the hot water storage tank to prevent the electric heater from running dry. It is a dog of industrial value that provides a highly safe dishwasher.
