Description

[Detailed description of the invention] Industrial applications The present invention relates to a household dishwasher.

Structure of the conventional example and its problems The basic structure of this type of dishwasher, as shown in FIG. , a door 7, a backing 8, etc., a certain amount of water is supplied from a water supply solenoid valve 4, and the washing water pressurized by a washing pump 2 is sprayed onto tableware 9 installed in rank 6. , It was supposed to be washed.

On the other hand, a conventional dishwasher operation program generally starts with a pre-washing process 11, and consists of a washing process 12, a rinsing process 13, and a drying process 14, and each process is automatically sterilized by a time switch, etc. The system was such that it would be done. Furthermore, in the pre-washing process 11, the washing process 12, and the rinsing process 13, a certain amount of water is supplied from the water supply solenoid valve 4 at the beginning of each process, and the washing water is pressurized and circulated by the washing pump 2, and the washing water is poured into the tableware 9. The system was designed to spray dirty water to clean the machine for a certain period of time, and then, after a certain period of time had elapsed, the washing pump 2 was stopped and the drainage pump 3 was started to discharge the dirty water to the outside of the machine. In particular, the rinsing process was repeated several times until the washing water became clean. After the rinsing process is completed, the heater 10 is energized to heat and dry the inside of the washing tank 1° and the tableware 9. Furthermore, as shown in Figure 2, the operating programs include a program that runs the entire process from pre-washing to drying ■, a program that runs from washing to drying ■, a program that runs from rinsing to drying ■, and a program that only pre-washes ■. ,
The system allows you to select a program according to each purpose using a selection switch, etc., but for example, if you want to dry hand-washed dishes, you can further improve the functionality by setting up a drying-only program. Dishwashers did not have a built-in drying only program, and if you wanted to dry hand-washed dishes, you would use a dish dryer that only had the function of drying dishes. However, since the functions of dish dryers are limited, they do not fully satisfy the users.Furthermore, in dish dryers, the user must drain the water that has accumulated in the chamber himself/herself each time. It also had some aspects that made it difficult to use in practice.

OBJECTS OF THE INVENTION The present invention solves the conventional problems by providing a drying only function during the selection program of a dishwasher that automatically operates each step of prewashing, washing, rinsing, and drying.

The purpose of this program is to improve the functionality of dishwashers.

Structure of the Invention The present invention is a dishwasher that can automatically operate each step of pre-washing, washing, rinsing, and drying, and it is possible to select whether to operate all or part of the steps depending on the purpose of use. , this selection process includes at least a program with only a drying process, and a drainage process is provided in the process of this drying only program, so that dishes can be stored cleanly.
It is.

DESCRIPTION OF EMBODIMENTS The structure of the present invention starts with a pre-washing process 11, washing process 12, rinsing process 13, and drying process 14. Each of these processes is automatically operated, and all processes are operated. It has a function that allows you to select a program to run a part of the process, or a program to run a part of the process. If program I is selected now, the pre-washing, washing, rinsing, and drying steps are automatically operated to wash and dry heavily soiled dishes. If program ① is selected, the washing, rinsing, and drying processes are automatically operated, and the washing and drying functions can be performed for ordinary dirty dishes. In this way, it is possible to improve the functions of a dishwasher by providing many programs depending on the purpose, but conventionally, from a practical and cost perspective, the programs shown in Figure 2 are Generally, programs from I to ■ were provided. However, in this embodiment, by adding a program only for the drying process, the functionality can be further improved and a new dishwasher can be provided that combines the functions of a conventional dishwasher and a dish dryer. It is something. In particular, in the drying-only program V, a drain step 15 is provided at the beginning, middle, or end of the program to operate the drain pump 3. Furthermore, by draining the water accumulated in the cleaning tank 1 to the outside of the machine, the drying performance is improved and the inside of the cleaning tank 1 is always kept clean. In the drying process, the inside of the washing tank 1 and the dishes 9 are heated and dried by energizing the heater 10, but other methods such as blowing hot air into the washing tank 1 are also conceivable.

Effects of the Invention In the present invention, the dishwasher can be used as a dish dryer by providing a drying only program, which improves the functionality of the dishwasher. The provision of this process has great practical effects, such as improved drying performance and the ability to always store tableware cleanly.
