Description

  The present invention relates to a dishwasher. More specifically, the present invention relates to a dishwasher that prevents foreign matter from entering a machine from a water supply pipe during a trial run after installation.

Recently, the penetration rate of dishwashers has increased, and dishwashers are often installed at the time of new construction or renovation of houses. There are many foreign substances such as iron powder generated during construction in the water supply equipment piping of new houses and renovated houses. Therefore, it is necessary to remove foreign matters in the water supply equipment piping before installing the dishwasher and performing a test run. Foreign matter in the water supply equipment piping can be easily removed by flowing a certain amount of water.
However, there are no facilities such as sinks and waterproof pans at the planned installation location of the built-in dishwasher built in the system kitchen, and the water supply and drainage pipes with stop cocks only protrude from the floor and walls. Therefore, until the water supply hose of the dishwasher is connected to the water supply pipe and the drainage hose of the dishwasher is connected to the drain pipe, the water faucet cannot be opened because the water cannot be drained. Therefore, water is supplied to the dishwasher before the foreign matter has been removed. If water mixed with foreign matter is supplied into the machine through the water supply hose of the dishwasher, the water supply electromagnetic valve may bite the foreign matter. If the water supply solenoid valve bites in a foreign object, it will cause the valve to close poorly and lead to a water leak accident. Moreover, the built-in type dishwasher is planned to be installed at a position below the counter of the system kitchen, and if a water leak accident occurs, repair work becomes difficult. Therefore, usually, measures such as attaching a filter to the water supply hose are taken in order to prevent entry of foreign matter. However, even if a filter is attached, it is difficult to completely prevent foreign matter from entering the machine.

  In view of this, several techniques have been disclosed in which it is assumed that a poor closing of the water supply valve occurs when a foreign object is caught in the water supply valve, and the poor closing of the water supply valve is promptly resolved. For example, in the dishwasher of Patent Document 1, when a poor closing of the water supply valve is detected, the water supply valve is forcibly opened for a predetermined time and the drainage pump is driven to remove the foreign matter biting into the water supply valve. Remove by flushing with water supply. Moreover, in the dishwasher of patent document 2, when the poor closing of a water supply valve is detected, the foreign material which had bitten into the water supply valve is removed by repeating the opening / closing operation | movement of a water supply valve several times.
