BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwashing system in which a water heater and a dishwashing device are connected via a hot water supply pipe.

[0002]

2. Description of the Related Art Usually, a dishwasher of this type is provided with a storage tank for storing a predetermined amount of water in a washing chamber for storing dishes, and when cleaning, a predetermined amount of water is stored in the storage tank. Is stored, and the water is jetted toward the dishes through a nozzle by a washing pump to perform washing. The water after cleaning is stored again in the storage tank, and the above operation is repeated. During that time, drainage and water supply are performed appropriately.

When dishwashing is performed in this type of dishwashing apparatus, hot water at an optimum temperature (generally set to 60 ° C.) is used to improve washing efficiency. Therefore, a heater is provided in the storage tank to heat and keep the water in the storage tank at an optimum temperature for cleaning.

In recent years, there has been known a dishwashing system in which a water heater is connected to a dishwashing apparatus and the hot water of the water heater is used when washing dishes. A water heater is well known as a facility for supplying hot water to a sink in a bath or a kitchen, and this kind of dish washing system is one in which a dish washing device is additionally connected to a hot water pipe of the water heater. In addition, the water heater starts and stops the operation of the water heater by a user operating a remote controller or the like connected to the water heater, and the hot and cold water for bath water heating or kitchen water heating is brought to a desired temperature. It can be set. According to this, when washing dishes, the user sets the temperature of hot water at the time of hot water supply to a temperature suitable for dish washing by the remote controller or the like, so that the heating time by the heater in the storage tank of the dish washing apparatus is significantly increased. It can be shortened, and the operation time at the time of dish washing can be shortened.

[0005]

However, in the dishwashing system as described above, the user sets that the water heater is stopped and that the hot water supply temperature of the water heater is set to a temperature not suitable for dishwashing. There is a risk that the dishwasher will start to wash the dishes without noticing that it has been done. When the water heater is stopped or the set temperature of the water heater is set lower than the temperature suitable for dishwashing, water or low-temperature hot water is supplied to the dishwashing device. Even though the water heater is connected, the cleaning time cannot be shortened because it takes a long time to heat the heater. Also, if the set temperature of the water heater is set to a temperature higher than the temperature suitable for dishwashing, the protein attached to the dishes during dishwashing will solidify due to the temperature of the hot water and the state of attachment to the dishes will be reduced. It becomes strong and cleaning efficiency decreases.

In order to eliminate such inconvenience, the present invention surely shortens the operation time during dishwashing by prompting the user to set the hot water supply temperature of the water heater when washing the dishes in the dishwasher.
