Description

Cleaning device for metal container

The invention provides a cleaning device for a metal container.

In metal containers (hereinafter referred to as containers) such as thermos bottles and electric kettles, beverages (contents) such as coffee, tea, soup, etc. are often stored repeatedly, which may cause the inside of the container to change color and adhere to dirt. If this kind of dirt is washed repeatedly (for example: washing with water or neutral detergent), it will not fall easily but will slowly deposit on the inside of the container, even if it is wiped with sponge, etc., it will not fall easily. In this case, the user must use a cleaning solution in which oxygen bleach is dissolved to clean the inside of the container. However, when using an oxygen bleach, the inside of the container must be immersed in the container. The cleaning solution takes several hours to several tens of hours, which is very time consuming. Therefore, it is impossible to respond to the need to clean the container in a short time.

Therefore, by using a cleaning solution that electrolyzes the inside of the container, and using the hydroxyl radical generated by the cleaning solution, dirt attached to the container can be removed in a short time. (Please refer to Patent Document 1). Specifically, in Patent Document 1, a cleaning device is provided on the top of a container, and an electrode rod that is a positive electrode is immersed in a cleaning solution in the container to make a negative electrode. In a state where an electrode pad or an electrode arm is in contact with the upper edge or the inner wall surface of the container, a voltage is applied between the positive and negative electrodes.

In addition, in conventional cleaning devices, the user must The electrode pad or electrode grip arm is in contact with the metal part of the container. However, when the electrode pad cleaning device is used for the negative electrode, it cannot be used to cover the upper edge of the container with a lid member (insulating member) such as plastic. On the other hand, when the negative electrode is used in the cleaning device of the electrode grip arm, it cannot be used in the type with a narrow container opening, and the front end of the electrode grip arm cannot touch the inner wall surface of the container (non-contact).
