2. Description of the Related Art Recently, chemical substances generated from house building materials and furniture have an adverse effect on the human body, and particularly in newly built houses, many cases of harmful health have occurred, which has become a social problem. Most of them are harmful chemical substances such as formalin gas generated from new building materials. Efforts to reduce these harmful chemicals are being actively carried out by building material manufacturers and others, but the results have not been satisfactory yet, and removal of harmful substances from the air is indispensable for maintaining the health of residents. is necessary. On the other hand, although an excellent effect of adsorbing formalin or the like on tea leaves has been reported, there is no invention of an apparatus for drying wet used tea leaves and automatically operating the same equipment until air cleaning in the same appliance.

[0003]

There is a need for an effective substance that rapidly absorbs toxic chemical substances generated from homes, especially new building materials, and excludes them from the air. It has been reported that tea leaves are extremely effective for adsorption, and it is said that tea leaves extracted and used are sufficient for the adsorption. However, the tea leaves immediately after use are wet, and if left as it is, decay and the like proceed, so that the tea leaves need to be dried quickly. If it is possible to dry tea leaves and clean the air in the same instrument, it is possible to save energy and remove harmful substances. Therefore, the present invention is an electric appliance that automatically dries used wet tea leaves and circulates indoor air inside to remove toxic chemicals.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic structure of the present invention resides in a mechanism having both a function of drying used wet tea leaves and a function of adsorbing toxic substances circulating in the air. That is, the subject of the present invention is an idea of performing drying of tea leaves and air cleaning in the same appliance. An appliance having both a tea leaf drying function and an air circulation function belongs to the category of the present invention. Concretely, an inlet (lid) for introducing tea leaves into a device, a drum for drying tea leaves (there may be a propeller shaft for stirring tea leaves inside), a heater for drying tea leaves, a fan for taking in air and blowing air, drying Humidity sensor for instrument and temperature sensor in instrument, filter for dust adsorption, motor for drum operation, electronic control device for controlling the entire operation, collecting tray for water droplets, dust, etc.
It is composed of parts such as an outlet for removing the water droplet dust and the like and a structure including these parts. Add an air intake and a vent to this. Explaining the purpose of use of each part according to the actual operation, the wet tea leaves are opened into the appliance by opening the lid of the inlet, and then the tea leaves are connected to the inlet and the tea leaf drying drum The excess water drops drop down further. There is a water and dust collecting tray below the drying drum, and the water and dust collect in the lower collecting tray. When the water and dust outlet at the bottom of the instrument is opened, unnecessary water and dust are discharged out of the instrument. it can. When the inlet is closed and the device is started, the drum (or the propeller for stirring inside the drum) rotates and the tea leaves are stirred inside, the heater for drying tea leaves is heated,
By starting the blower fan, the heated air starts drying the wet tea leaves in the drum. The progress of the drying is monitored by a humidity sensor for detecting the drying and a temperature sensor, and the data is constantly sent to an electronic control unit to be monitored. Air intake (after passing through the dust adsorption filter)
Newer air is taken into the instrument and blows out of the instrument from the outlet. At this time, the air comes into contact with the tea leaves,
Harmful substances are adsorbed on tea leaves. The function of the humidity sensor and temperature sensor for drying detection
The output of the drying heater is controlled by the control of the electronic control device, and the control of the entire air blow is also performed. When new used tea leaves are generated, they may be further added to this instrument. On the other hand, when the tea leaves are full in the instrument, take them out of the slot, pack them in a bag (in this case, it is more convenient to remove the tea drying drum) and leave them in the furniture or indoors. Thus, the effect as an adsorbent for toxic substances can be expected, and its use as an apparatus for drying used tea leaves can also be expected. As a daily maintenance management, extra water droplets and spilled dust may be taken out of the instrument from the bottom water drop / dust extraction port and discarded.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The concrete working method will be further described with reference to FIG. 1. The extracted and used wet tea leaves are put into a drying inner cylinder inside the instrument from an input port. The inner cylinder is mesh-shaped or porous so that air can easily pass therethrough in order to ensure air permeability, but a structure that does not leak tea leaves is required. In order to restrict the roll of the inner cylinder, an outer cylinder is set and the inner cylinder is held. The outer cylinder must also have sufficient air permeability. The air in the instrument is forcibly taken in from outside by an air intake fan, circulates in the instrument, and is discharged from the air outlet. At this time, the tea leaves are touched to adsorb toxic substances to the tea leaves and promote the drying of the tea leaves. The wet tea leaves are stirred by rotation of a motor connected to the inner cylinder or rotation of a tea leaf stirring propeller installed inside the inner cylinder. Agitation of tea leaves is indispensable and effective for adsorption and drying of toxic substances. Water droplets and tea leaf powder leaking from the inner cylinder are caught in a lower collecting tray, and the tray portion is designed to have a structure that can be easily cleaned from the removal / extraction port. Drying of wet tea leaves requires drying and heating of the air inside the instrument.Humidity sensors and temperature sensors are installed to control the heater for air heating and to stop the heater when drying is completed. Then, electronic control is performed. In addition, as a control mechanism that incorporates the user's requirements (time, wind, etc.)
This electronic control device is used for overall control.
When the amount of tea leaves inside the machine increases, it is desirable to have a mechanism in which only the inner cylinder is removed for taking out the tea leaves and can be taken out, so that a mechanism for removing the inner cylinder and a mechanism for connection are provided.

[0006]

According to the present invention, the relatively simple electric appliance can effectively use the waste of extracted and used tea leaves,
The effect of two birds per stone can be expected when considering environmental conservation, such as removing toxic chemicals in the room. If the health of residents, such as new housing, can be maintained using waste, the social effects are considered to be enormous.
