2. Description of the Related Art Garbage disposal equipment is originally intended for kitchen garbage (organic matter).
In the presence of, an aerobic bacterium is grown by supplying an appropriate amount of water and oxygen, and is decomposed by the bacterium. However, depending on the input amount and the garbage to be input, the amount of water may be excessive, resulting in a shortage of oxygen supply, a phenomenon such as hardening of the processing base material, which may promote the generation of odor or shorten the life of the processing base material. become. Therefore, it is an important point to adjust the water content in the tank with the kitchen waste treatment apparatus.

In the prior art, as measures for solving such problems, JP-A-7-185508, JP-A-7-96269 and JP-A-7-18 are disclosed.
No. 7308 has been filed.

FIG. 5 shows the details of the conventional technique disclosed in Japanese Patent Application Laid-Open No. 7-185508. In FIG. 5, reference numeral 1 denotes a processing tank into which garbage is put, 3 denotes a lid, and 4 denotes an outer case. 6 is a processing base material prepared in advance in the processing tank 1,
Reference numeral 7 denotes a stirrer for mixing a material to be processed consisting of kitchen waste and the processing base material 6. 9 is a blower for ventilating the inside of the processing tank 1. Reference numeral 12 denotes a shooter which is easy to receive when throwing garbage, and 13 denotes a throwing shutter which does not emit odor from inside when throwing garbage into the processing tank 1. Reference numeral 14 denotes a humidity sensor which is a central element of the present invention and detects humidity in the processing tank 1.

The conventional technique disclosed in Japanese Unexamined Patent Publication No. Hei 7-187308 prepares a dew condensation sensor and operates a blower when dew condensation is detected (not shown).

[0006]

As described above, in the conventional kitchen waste processing apparatus, the humidity in the processing apparatus is detected by the sensor. This is described as an effective means for changing the detected value into an electric signal and automatically operating the blower.
However, the humidity sensor has a drawback that accuracy cannot be maintained due to surface contamination. This problem is remarkable in an environment in which a processing base such as sawdust is liable to be turned into fine powder, such as a kitchen waste processing apparatus, and in which an agitator and a blower are operated. Then, when the surface of the humidity sensor becomes dirty, it is detected in a direction in which the humidity increases, so that the blower is operated. Therefore, unnecessary energy is used. In addition, since the humidity sensor is expensive, it is not practical to replace it frequently in the present situation where an inexpensive device such as a household kitchen waste disposal device is required.

[0007] Further, in the case of automatic control, even if a large amount of garbage is put in, the air continues to be blown until the humidity drops, and an unreasonable operation is performed, resulting in shortening the life of the treated base material.

The present invention makes it possible to simply and accurately detect the humidity in a processing tank by using a humidity indicator card, and it is possible to put garbage in accordance with the humidity, thereby suppressing odors, It is an object of the present invention to obtain a garbage disposal device capable of extending the life of a substrate.

In order to achieve the above object, the present invention uses an inexpensive and easy-to-handle humidity indicator card which stops automatic control.

The humidity indicator card is set so that a predetermined humidity can be detected at certain intervals, and it is sufficient to read the humidity where the color changes from blue to pink. It is reversible and returns to its original blue when the humidity drops.

According to the present invention, in order to extend the service life of the humidity indicator, the waste heat of the heater is used to dry it normally, and when the lid is opened at the time of putting in the garbage, the humidity is manually placed on the processing tank side. When the detection object is moved and the humidity in the processing tank is detected, the state is returned to the original state. The input of kitchen garbage is executed according to the detection display on the humidity indicator card. If the operation cannot be restarted unless the humidity detector is returned to the original position, the durability of the humidity indicator card can be reliably maintained.

Incidentally, the humidity indicator card deteriorates,
When the color no longer changes, it is necessary to replace it. Therefore, the humidity indicator card holding portion of the humidity detector is taken out and has a structure that can be easily fitted.

According to the first aspect of the present invention, there is provided a kitchen waste treatment apparatus, wherein a treatment tank for fermenting the material to be treated, a stirring device for stirring the material to be treated in the treatment tank, and ventilation of the inside of the treatment tank. And a heater for heating the inside of the processing tank, wherein a reversible humidity indicator card is used for detecting humidity in the processing tank.

[0014] In the garbage disposal apparatus of the second invention, the humidity detector holding the humidity indicator card is located at a position for receiving the residual heat air of a heater provided outside the processing tank for heating the processing tank. It is arranged so that it can be moved to a position for receiving air in the processing tank only when it is desired to measure humidity.

In the garbage disposal apparatus according to a third aspect of the present invention, the stirrer is stopped unless the operating member for operating the stirrer is brought into contact with the humidity detector at a fixed position.

According to a fourth aspect of the present invention, a humidity indicator card is detachably mounted on the humidity detector.

According to a fifth aspect of the present invention, there is provided a garbage disposal apparatus wherein the limit of the amount of garbage to be thrown is displayed according to the humidity detected by the humidity indicator card.
