Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dishwasher for general household use.

Conventional structure and its problems The structure of a general dishwasher is as shown in the drawings. That is, 1 is the main body of the dishwasher, 2 is a washing tank installed inside the main body 1, 3 is a washing pump that circulates washing water in the washing tank 2, and is rotationally driven by a washing pump motor 4.
The cleaning water is sucked through the drain hole 5 and flows through the lower cleaning nozzle 6.
and is sprayed by the upper cleaning nozzle 7. Also, in order to wash the dishes efficiently, there is a bottom where the dishes can be arranged in an orderly manner.8. The upper vane 9 is installed in the cleaning tank 2. 1o is an exhaust port that communicates the cleaning tank 2 with the outside air, and discharges steam during drying. The driving cycle will now be explained. Conventionally, the operating cycle of a dishwasher generally starts with a pre-washing process, then consists of a washing process, a rinsing process, and a drying process, and each process is automatically controlled by a time switch, etc. There is. Furthermore, there is a pre-washing process and a cleaning process.

In the rinsing process, a certain amount of water or hot water is supplied at the beginning of each process, and immediately the washing pump 3 pressurizes and circulates the washing water, and sprays it onto the dishes to wash them.

This is for rinsing. Here, when hot water with a fairly high temperature (1) is supplied and the cleaning pump 3 is operated immediately, the cold air in the cleaning tank 2 is suddenly warmed and expands, and is blown out from the exhaust port 10 together with the cleaning water. There was a problem with putting it away. In addition, even when the door is opened and closed during operation and the operation is restarted, the steam in the cleaning tank 2 is replaced with outside air and hot cleaning water is spouted into the cold cleaning tank 2. There was a problem that the same phenomenon as 313,-7 occurred.

Purpose of the Invention The present invention solves these conventional problems and provides a dishwasher that supplies high-temperature hot water and does not spray out washing water from the exhaust port even if the door is opened or closed during operation. It is something to do.

Structure of the Invention The dishwasher of the present invention has a hot water temperature detection device, and if the hot water temperature is above a certain temperature, the washing water injection operation is started after hot water is supplied, and after the door is opened and closed during operation. It has a control program that waits a certain period of time before restarting the cleaning water injection operation, so even if the water temperature is high, the inside of the cleaning tank will be filled with steam whenever the cleaning water injection operation starts. Since the tank is warmed up by heating, it is possible to prevent the air inside the cleaning tank from rapidly expanding, and it is also possible to prevent cleaning water from spouting out from the exhaust port.

Description of examples An embodiment of the present invention will be described based on the drawings.

Reference numeral 11 denotes a hot water temperature detection device installed at the bottom of the cleaning tank 2, which can easily detect the temperature of the cleaning water. A trench cleaning tank? The hot water temperature detection device 11 detects when the temperature of the hot water supplied to the water exceeds a certain temperature, and after supplying the hot water, a control program is executed to set a certain period of time between the washing water injection operations. make it work. Therefore, during that time, the inside of the cleaning tank 2 is filled with steam from the cleaning water, and the air inside the cleaning tank 2 is warmed, so that even if the operation is continued thereafter, the cleaning water will not be spouted out from the exhaust port 10. Even if the door is opened and closed during hot water operation, the air inside the cleaning tank 2 is replaced with outside air, and the inside of the cleaning tank 2 becomes cold. Because of the spacing, the cleaning water injection operation starts when the inside of the cleaning tank 2 is warm, and no cleaning water is sprayed out from the exhaust port 1o.

Effects of the Invention As is clear from the above embodiments, the dishwasher of the present invention detects the water temperature, and if the water temperature is above a certain level, the water temperature is detected before the washing water injection operation starts after hot water is supplied or after the door is opened or closed during operation. By waiting for a certain period of time, the inside of the cleaning tank 6 vane can be warmed, and the effect of preventing the cleaning water from spouting out from the exhaust port can be measured.
