Description

Heater mstitution structure of dishwasher

The present invention relates to a heater installation structure of a commercial dishwasher, and more particularly, to install a heating unit of the heater installed in the washing water tank or the rinsing water tank to heat the water for washing or rinsing so as not to directly contact the water It prevents the build-up of water on the scale and efficiently dissipates heat, and prevents the heater from being damaged by the scale, thus extending the life of the heater.In addition, the water in the washing water tank or the rinsing water tank during the replacement work of the heater. It can be replaced without removing the water, which can prevent unnecessary water loss and shorten the time required for replacement work. In addition, the heater is damaged by the drainage rod when installing and removing the drainage rod in the wash water tank. It also relates to a heater installation structure of a commercial dishwasher that can be prevented in advance.

In general, restaurants such as restaurants use a lot of commercial dishwashers (hereinafter referred to as dishwashers) to wash a large amount of tableware, and when installing the dishwasher in a kitchen, most of them use a boil bath. It is installed so that the dishwasher main body is placed between and the drying rack.

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, looking at the structure and function of the dishwasher, the dishwasher is rotatably installed with a pair of upper / lower washing nozzles and upper / lower rinsing nozzles on the bottom surface and the center of the upper surface of the washing chamber, which are mostly opened by a liftable lid on the upper side. The upper and lower washing nozzles disperse water toward the dishes in the rack placed in the center of the washing chamber, and face the washing step, and the upper and lower rinsing nozzles are configured to perform the rinsing step by spraying water toward the washed dishes.

In addition, a washing water tank and a rinsing water tank are installed inside the washer body under the washing chamber, and a washing motor that pumps water from the washing water tank to the upper and lower washing nozzles and pumps water from the rinsing water tank to the upper and lower sides. A rinse motor supplied to the rinse nozzle, a circuit board of the control unit for controlling an operation program of the dishwasher, and the like are provided.

The hot water supplied through the water supply line after being preheated to about 42 ℃ ~ 52 ℃ 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. It is.

In addition, 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 in the washing water tank and the rinsing water tank, and the water of the washing water tank is approximately 60 ~. The water of the rinsing water tank is heated to 65 ° C. and heated to approximately 80 ° C. to 85 ° C. or higher hot water, so that the drying effect can be obtained together with the sterilization effect of the dishes being rinsed.

Most of the operation parts of the dishwasher put the rack containing the dishware in the washing room with the power on / off switch "on", and when the lid is lowered and closed, 60 to 65 ° C of the washing water tank is sprayed to the upper and lower washing nozzles. The washing step is performed, and when the washing step is completed, hot water of 80 ° C. to 85 ° C. of the rinsing water tank is sprayed into the upper and lower rinsing nozzles so that the rinsing step of rinsing and sterilizing is performed.

  Here, the water in the rinsing water tank is heated to 80 ° C ~ 85 ° C or higher by the heater after receiving water from the instantaneous water heater, which is reduced by performing the rinsing step once, and the high temperature (80 ° C ~ 85 ° C) used in the rinsing step. ), The temperature of the water is lowered to 60 ℃ ~ 70 ℃ in the process of rinsing the dishes, but can be said to be higher than the water temperature (60 ℃ ~ 65 ℃) 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 wash water temperature in the wash water tank gradually increases while the dishwasher is running due to the incoming water temperature. The internal washing water is structured so that some of the washing water flows out of the dishwasher through the overflow hole whenever the water level rises.

However, the conventional heater in the dishwasher operated by such a structure has a number of problems as described in detail as follows.

That is, as shown in FIGS. 1 to 3, the washing water tank 20a and the rinsing water tank 20b installed in the washing main body 10 to wash the water to an appropriate temperature are provided in the washing water tank 20a or the rinsing water tank. As the inside of the 20b, the terminal portion 32 of the heater 30 projects out of one side wall 21 of the washing water tank 20a or the rinsing water tank 20b, and the heat of the heater 30 dissipates heat. The heating part 31 is installed to protrude into the washing water tank 20a or the rinsing water tank 20b.

However, when the heating part 31 of the heater 30 that radiates heat protrudes into the washing water tank 20a or the rinsing water tank 20b, the heating part 31 is always submerged in water, and thus the scale is Since it is easily caught on the surface of the heating part 31, and the heat conduction state becomes poor, the heat generated from the heating part 31 is not properly conducted, so that it takes a long time to heat the water, and the trouble caused by the water is frequent. There arises a problem that the life of the heater 30 is shortened by that.

In particular, when the washing and rinsing water enters the washing water tank 20a to be reused, food wastes, etc., which have been stained with the utensils, enter together, and thus, the heating part 31 of the heater 30 installed in the washing water tank 20a. ) Will have more scale.

In addition, conventionally, since the heater 30 is installed inside the washing water tank 20a or the rinsing water tank 20b, when the heater 30 needs to be replaced due to a failure of the heater 30, the washing water tank 20a or rinsing is performed. The replacement of the heater 30 in the state in which all the water in the water tank (20b) has been removed, there is a loss of unnecessary water, the work time for replacing the heater 30 also takes a long time.

In addition, since the heating unit 31 of the heater 30 is submerged as described above, the underwater heater is used, which is expensive and requires a long installation time to prevent electric shock.

In addition, the washing water tank 20a is provided with a water repellent rod 40 that overflows when there is a lot of water. In the related art, when the water repellent rod 40 is removed while the heater 30 is installed, the water repellent rod 40 is slightly inadvertently inserted. ) Is in direct contact with the heating unit 31 of the heater 30, the heating unit 31 is damaged and there is a closed end to shorten the life of the heater 30 in this case.

Therefore, the present invention is to solve such a conventional problem is that the object of the present invention is installed so that the heating portion of the heater is not in direct contact with the water to prevent the pinch caught in the heating portion so that the heat is efficiently conducted conduction It prevents the heater from being damaged by scale and extends the life of the heater.Also, it is possible to replace the heater without removing the water in the wash water tank or the rinse water tank. It is to provide a heater installation structure of the commercial dishwasher to shorten the time required, and also to prevent the heater from being damaged by the drainage rod when the drainage rod in the wash water tank is separated or installed.

In order to achieve the object of the present invention, the present invention is to install a heater consisting of a heating unit and a terminal unit in the wash water tank or the rinsing water tank to heat the wash water or rinsing water supplied into the washing body for commercial use, washing water tank or rinsing water A heater fitting hole is formed on one side wall of the tank, and a heater installation part into which the heater is fitted from the outside through the heater fitting hole is formed in a protrusion in the washing water or the rinsing water tank so that the heater is filled in the washing water tank or the rinsing water tank. It is characterized in that it is installed from the outside through the heater fitting hole without being in direct contact with water.

As such, the present invention prevents water from being caught in the heating part by directly heating the heater by the heater installation part, so that heat can be dissipated efficiently, as well as preventing the trouble caused by the water. Therefore, it is possible to extend the life of the heater, and it is not necessary to drain the water in the washing water tank and the rinsing water tank during the replacement of the heater, thereby preventing unnecessary water loss and shortening the time required for the replacement operation. Since contact with the heater can be avoided during installation and removal of the rod, there is an effect of preventing the heater from being damaged.

Hereinafter, with reference to the accompanying drawings, the technical configuration and operation effects as a preferred embodiment that can effectively achieve the features of the present invention will be described.

To enter the heater installation unit 212, the terminal 320 of the heater 300 is protruded to the outside of the side wall 210 of the wash water tank (200a) or rinsing water tank (200b).

Since the end of the heater 300, while opening and closing the heater fitting hole 211, the fixing unit 330 for installing the heater 310 is placed in the heater installation unit 212 inside the washing water tank (200a) or rinsing water When detachably fixed to the side wall 210 of the tank 200b, the heater 300 is installed in the washing water tank 200a or the rinsing water tank 200b.

Thus, when the heater 300 is installed to protrude into the washing water tank 200a or the rinsing water tank 200b in a state in which the heating part 310 of the heater 300 is wrapped with the heater installation part 212, the washing water tank 200a. Alternatively, even if water is put into the rinsing water tank 200b, the heating unit 310 does not come into contact with the water at all, and only the heater installation unit 212 maintains the state in contact with water. The water will not be caught in the 310.

Here, the heater installation unit 212 is emitted from the heating unit 310 even if the heating unit 310 of the heater 300 for dissipating heat by using a material having excellent heat conduction is wrapped in the heater installation unit 212. The heat is efficiently conducted to the water of the wash water tank (200a) or rinse water tank (200b).

In this way, the heating unit 310 of the heater 300 enters the heater installation unit 212 formed in the washing water tank 200a or the rinsing water tank 200b, and thus, the outside of the washing water tank 200a or the rinsing water tank 200b. Since the heater 300 is installed in the heater 300, even when the heater 300 is removed, only the fixing part 330 for fixing the heater 300 is separated, and then the heater 300 is pulled out and the heating part of the heater 300 ( When the 310 is released from the heater installation unit 212, since the heater 300 is easily separated from the washing water tank 200a or the rinsing water tank 200b, the present invention provides a washing water tank during the replacement operation of the heater 300.
