Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dishwasher, and particularly to a dishwasher that is efficient and free from corrosion.

Structure of conventional example and its problems A type of tableware device that heats water with a sheathed heater, sprays the water onto plates and bowls, washes the dishes, and then heats the sheathed heater to dry the dishes has been developed in recent years. , its penetration rate has been increasing, especially in ordinary households.

In such a dishwasher, the sheathed heater is heated with detergent and food stains (salt, soy sauce, etc.) in it, and then the sheathed heater is heated in the air to dry the food. Through this series of repetitions, the corrosion resistance of the sheathed heater was the most important control item. In order to satisfy corrosion in liquid and temperature-challenged oxidation in fully fired conditions, the pipe material had to be of a higher grade, or the entire heater had been lengthened to reduce the degree of dry firing (lower temperature).

In addition, the sheathed heaters used for this purpose are mainly metal pipes with a shiny finish or with a thin oxide film attached. , and the emissivity of far-infrared rays, which are effective for heating water, was low.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides a dishwashing device that efficiently heats water and dries dishes, and does not lose its corrosion resistance even when repeatedly heated in water and in the air. be.

Structure of the Invention The present invention is equipped with a body part for storing water, a storage section for storing tableware, a sheathed heater for heating water, and a nozzle for spouting heated water. After cleaning the dirty dishes with a jet stream, a sheathed heater is used to heat the dishes in the air to dry the dishes.The surface of the sheathed heater's metal pipe is coated with a ceramic coating made of heat-resistant hollow, which increases the far-infrared emissivity. It is a tableware method that can improve corrosion resistance as well as improve corrosion resistance.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIG. 1.The tableware utensil of the present invention is modeled as shown in FIG. It has a storage part 4 for storing so-called tableware 3 such as forks and fork knives, and this storage part has a bar-shaped and vertically protruding body 5 on which the tableware 3 can be propped up. The method of using this dishwashing device is to first organize the dirty tableware 3 after a meal in the storage section 4, then pour the water 1 into the body part 2.
Detergent etc. are added and heated with a sheathed heater 6, and the tableware 3 is washed with the heated water 1.

After discarding the dirty liquid, rinse with clean water and discard.

Thereafter, the sheathed heater 6 is energized to warm the atmosphere and sterilize the tableware 3 by drying.
In other words, it is necessary to withstand both corrosion caused by washing with tap water containing detergent, tap water containing salt, soybean oil, etc., and dry corrosion due to aerial oxidation.

Therefore, the configuration of the sheathed heater 6 is important in the present invention. 03US316L, 5U will be explained below with reference to FIG. 2, which shows an enlarged view of the sheathed heater.
S321 and N G p'soo.

A heat-resistant and corrosion-resistant alloy such as NCF600 is used as the pipe 8, and SiO□ is applied to the surface of the sheathed heater pipe 8, which has an insulating powder 9 such as MgO and a heating wire 10 inside, and is finished into an appropriate shape through a normal manufacturing process. - Ceramic coating film 11 made of heat-resistant hollow material mainly composed of BaO
Attach. -The heat-resistant foaming agent not only has good properties such as thermal expansion coefficient, adhesion, and corrosion resistance, but also has the aim of emitting more far infrared rays.

Or,,03. Coo, ZrO2, Fe2O2, etc. are added, and the resulting film is fired at a relatively high temperature (over 900°C) to withstand at least the total firing temperature of the heater. The sheathed heater 6 made in this way is attached to an appropriate part of the body 2 to complete the dishware.

Effects of the Invention The tableware used in this way can be used in a corrosive environment where wet corrosion ← dry corrosion is repeated, corrosive substances such as salt and soy sauce are present, and jet water is present. , it maintains sufficient corrosion resistance and has the effect of being extremely resistant to corrosion.

■ The emissivity of far-infrared rays is higher than that of conventional sheathed heaters, so water heating efficiency is high, tableware drying efficiency is also high, and energy saving can be achieved.0 ■ Conventionally, to suppress corrosion,
Although the surface area of the sheathed heater has been increased to reduce the amount of heat generated per unit area, the sheathed heater of the present invention can be made more compact and can save space more efficiently.

It has such effects, and its value is that of a dog.
