Field of the Invention The present invention relates to a hood in a range hood having a hood and a blower, and a device for sucking smoke, steam, odor, etc. generated during cooking and discharging the same to the outside and cleaning the inside of the hood. The present invention relates to a device for mounting a cleaning liquid tank.

[0002]

2. Description of the Related Art A range hood is installed above a range and sucks smoke, steam, odor, etc. (hereinafter referred to as oily smoke) generated during cooking and discharges it to the outside.

[0003] As an example of this range hood, a fan and a filter are attached to a hood for catching oily smoke, and the blower is driven to suck in the oily smoke. Air and
A device that discharges the air to the outside through a discharge duct or the like is known.

[0004] In the above-described range hood, oil and the like adhere to the filter, so it is necessary to periodically remove the filter from the hood and clean it. However, since the hood is mounted above the range, it is cumbersome to remove the filter from the hood, it is easy to forget to clean the filter without noticing the dirt on the filter, and if you notice it, it will take a long time. In most cases, dirt adheres to and deteriorates the filter, and it is very troublesome to clean the filter.

[0005] As a range hood that solves the above-mentioned problem, there is known a range hood that cleans a filter disclosed in Japanese Patent No. 2604937, for example. This range hood is equipped with a receiving tank at the top and bottom of the filter,
The cleaning liquid in the lower liquid receiving tank is sent to the upper liquid receiving tank by a pump, and the cleaning liquid is caused to flow along the filter to wash away oil and the like attached to the filter.

[0006]

In the above described range hood, when the filter is washed, the washing liquid circulates between the upper and lower receiving tanks, and after the filter is washed, the washing liquid flows to the lower receiving tank. Since the cleaning liquid is accumulated, the cleaning liquid can be used repeatedly.

[0007] When the present inventors cleaned the filter for a long time by repeatedly using the cleaning liquid as described above, the cleaning effect of the filter gradually decreased, and finally the filter could not be cleaned.

As a result of intensive studies and experiments on the cause, the following has been found. Since the cleaning liquid is used to wash away oil and the like adhering to the filter, the cleaning liquid is contaminated by the oil and the like, and the cleaning effect of the filter is reduced. When the cleaning operation is not performed, the cleaning liquid stays in the lower liquid receiving tank, so that the inside of the lower liquid receiving tank is contaminated with the dirty cleaning liquid, and the dirt promotes the cleaning liquid.

[0009] From the above, in order to prevent the cleaning effect of the filter from deteriorating, it is necessary to replace the cleaning liquid,
It has been found that it is effective to clean the inside of the lower liquid receiving tank.

However, the above-mentioned range hood does not take the above into consideration at all, and it is very difficult to replace the cleaning solution and clean the inside of the lower receiving tank. However, it is practically impossible to clean the inside of the liquid receiving tank.

Accordingly, an object of the present invention is to provide a cleaning liquid tank mounting apparatus for a range hood which can solve the above-mentioned problems.
