Abstract

PURPOSE:To carry out a drying of grabage quickly without leaking odor outside using dry air. CONSTITUTION:This machine is provided with a drying section 12 which has a blower 18 on the upstream side of an adsorbing section 17 composed of an adsorbent 15 and a heater 16 and contains a blowing path provided with a suction port 19 at the upstream end thereof and an exhaust port 20 on the downstream side thereof, a drying chamber 11 connected to the drying section 12 with first and second air paths 13 and 14 and a control means for the blower, the heater and the switching of the air path. Air in the drying chamber 11 is sucked up with the blower 18 and after the dehumidification of the air with the adsorbent 15, the air is returned into the drying chamber as dry air thereby allowing the removal of the moisture of garbage efficiently and completely. Moreover, when the moisture adsorbed by the adsorbent 15 is released, with the switching of the air path, external air is sucked in and discharged outside thereby eliminating the leakage of smell of the garbage.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste dryer for dehydrating and drying food waste generated in a kitchen or kitchen.

[0002]

2. Description of the Related Art A conventional garbage drier of this type will be described with reference to the drawings. In FIG. 4, 1 is a drying chamber, 2 is an intake port, and 3 is an exhaust port. A blower 4 and a heater 5 are provided downstream of the intake port 1. Further, it comprises a blower 4 and a control means 6 for controlling the heater 5.

The operation of the above configuration will be described. When the operation is started, the heater 5 is energized by the control means 6, the blower 4 is activated, and the air is sucked from the intake port 2. The sucked air is heated by the heater 5 and sent as hot air into the drying chamber 1. Raw garbage 7 to be dried is put in the drying chamber 1, and water is taken away by the warm air. Since the air containing the moisture in the drying chamber 1 is discharged to the outside through the exhaust port 3, the moisture content of the raw garbage 7 decreases with time, and eventually the raw garbage 7 dries.

[0004]

However, in the above-mentioned conventional structure, since the drying is performed only by heating, it takes a long time to dry, and further, the drying time becomes longer when the external atmospheric humidity is high. there were. In addition, since the air in the drying chamber is released to the outside, there is a problem that the smell of raw garbage inside also comes out.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to dry food waste by using dry air quickly and without giving off an odor to the outside.

[0006]

A garbage drier according to the present invention has a blower on the upstream side of an adsorption section composed of an adsorbent and a heater, and has an intake port on the upstream end and an exhaust port on the downstream side. A drying unit having a built-in air passage, a drying chamber connected to the drying unit by first and second ventilation passages, on / off of the heater and the blower, and switching control of the air passage in the drying unit. The drying unit includes a first air passage switching unit that connects the upstream air passage of the adsorption unit to one of the intake port and the first ventilation passage, and a downstream air passage of the adsorption unit. A second air passage switching unit that communicates a passage with one of the exhaust port and the second air passage, the control means operates the blower in a non-energized state with respect to the heater, and The first and second air passage switching units are controlled, and the drying is performed through the first air passage. Adsorption operation control for sending the air in the chamber to the adsorption unit and further returning it to the drying chamber through the second ventilation passage, operating the blower while energizing the heater, and performing the first and the first operations. The second air passage switching unit is controlled to suck air from the intake port, send the air to the adsorption unit, and further, desorption operation control of discharging the air from the exhaust port are alternately repeated.

[0007]

According to the present invention, since the air in the drying chamber is sucked by the blower and dehumidified by the adsorbent and returned to the drying chamber as dry air by the above-mentioned structure, the moisture of raw garbage can be efficiently and completely removed. Can be taken. Furthermore, when releasing the water adsorbed by the adsorbent, the air in the chamber is sucked out and discharged to the outside by switching the air passage, so that the air in the chamber does not come out to the outside.
It can be dried quickly without leaking the smell of raw garbage.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1-3, 11 is a drying chamber, 12
Is a drying section, and both are connected by a first ventilation path 13 and a second ventilation path 14. In the air duct in the drying section 12,
An adsorption unit 17 including an adsorbent 15 and a heater 16 is provided, and a blower 18 is provided on the upstream side. Further, an intake port 19 is formed at the upstream end of the air passage, and an exhaust port 20 is formed at the downstream end. 21 on the upstream side of the adsorption unit 17 is a second air passage switching unit, and 22 on the downstream side is a second air passage switching unit, which is switched by the control means 23 together with the heater 16 in accordance with the operation mode. . The control means 23 is configured to alternately repeat the adsorption operation control and the desorption operation control described below.

In the adsorption operation control, as shown in FIG. 2, the first air passage switching unit 21 is connected to the first air passage 13 and the second air passage switching unit 22 is connected to the second air passage 14. The blower 18 is connected to the heater 16 without energizing the heater 16.
To drive. In this state, the air in the drying chamber 11 is sent to the adsorption unit 17 through the first ventilation passage 13 and the adsorbent 15 removes almost all the water. At this time,
The temperature of the dry air rises slightly due to the heat of adsorption generated together with the adsorption action. The dry air that has passed through the adsorbent 15 is returned to the drying chamber 11 again through the second passage 14. Dry air flows around the garbage 7 in the drying chamber 11 to remove water from the garbage. The moist air passes through the first passage and is again dried by the adsorbent.
As described above, in the adsorption operation control, the moisture of raw garbage is absorbed by dry air, and the moisture in the air is adsorbed by the adsorbent.

Next, in the desorption operation control, as shown in FIG. 3, the first air passage switching unit 21 is communicated with the intake port 19,
The second air passage switching unit 22 is communicated with the exhaust port 20, the heater 16 is energized, and the blower 18 is operated. At this time, the air sucked from the intake port 19 is heated by the heater 16 and becomes warm air and flows into the adsorbent 15.
The adsorbent 15 is heated by this warm air to desorb the adsorbed water. The air containing the desorbed moisture is exhausted to the outside through the exhaust port 20. Thus, in the desorption operation control,
The water adsorbed on the adsorbent is desorbed and is then discharged to the outside.

By repeating the above adsorption operation control and desorption operation control, it is possible to discharge only moisture without leaking the smell of raw garbage to the surroundings, and to efficiently dry raw garbage with dry air. it can.

[0012]

As described above, the garbage drier of the present invention produces dry air to remove moisture from the garbage.
It is faster than drying with warm air only, and the effect is constant regardless of atmospheric humidity. Further, since only the water is discharged to the outside without discharging the air in the drying chamber to the outside, the effect that the smell of the garbage is not leaked to the outside can be obtained.
