Abstract

PURPOSE:To realize a quick drying by a method wherein blowing air is turned into a dry hot air by using an absorbent. CONSTITUTION:A heat source 3 and a fan 5 are arranged in a wind passage 1 and an absorbent 2 is also provided there. The fan 5 is controlled by a control circuit 8 to rotate reversibly so that a flowing direction of introduced air can be switched between directions indicated by arrows 9 and 10. In the case that drying operation is carried out, air indtroduced by the fan 5 through a first communication port 6 is deprived of moisture it contains by absorption while it is passing through the absorbent 2, so that the air can become a dry air. The dried air thus obtained is then heated by a heat source 3 and diffused through a second communication port 7 as a hot air. If substance to be dried is placed in front of the second communication port 7, by contact with the dry air diffused out of the second communiction port 7, the substance to be dried is deprived of moisture it contains and dried.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer capable of performing rapid drying by using dry air as hot air blown out.

[0002]

2. Description of the Related Art A conventional dryer of this type will be described with reference to FIG. In FIG. 3, 01 is an air duct. Wind path 01
Inside the heating source 02 and the blower 0 for blowing air to the heating source 02
3 is provided. A suction port 04 is provided at the upstream end of the air passage 01, and an air outlet 05 is provided at the downstream end of the air passage 01. Further, it is composed of a control circuit 06 for controlling the heating source 02 and the blower 03.

The operation of the above structure will be described. When a main power source (not shown) is turned on, the control circuit energizes the heating source 02 to generate heat, and also activates the blower 03 to blow air to the heating source 02. By the above operation, the air 07 is supplied from the suction port 04, is heated by the heating source 02 to become warm air, and is blown out from the air outlet 05 to perform a predetermined drying.

[0004]

However, the above conventional structure has the following problems. (1) Since the drying is performed only by heating, the drying time is long. (2) Further, in order to shorten the drying time, it is necessary to raise the temperature of warm air, and there is a limit in terms of safety such as heat resistance of the constituent members and the material to be dried.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to realize rapid drying by using dry air as the hot air blown out.

[0006]

In order to achieve the above-mentioned object, the present invention provides an adsorbing section composed of an adsorbent and a heating source arranged in an air duct, and air in the adsorbing section in the air duct. The air blower includes a first communication port and a second communication port provided at both ends of the air passage, and a control circuit that controls the operation of the heating source and the blower. An ON signal is issued to the drying circuit at the time of the separation circuit and the start of operation, and an OFF signal is issued to the drying circuit at the end of the operation, and an ON signal is issued to the desorption circuit, and the desorption circuit receives the signal of the built-in timer circuit. A main control circuit that outputs an off signal is used as a means for solving the problem.

[0007]

According to the present invention, with the above-described structure, air is introduced into the air passage and heated by the heating source to be hot air. When the introduced air is heated, the adsorbent preliminarily removes moisture in the air. Removed and made dry air. Therefore, the blown-out air is a dry hot air that does not contain moisture, and the rate of removing moisture when contacting an object to be dried is faster than the conventional means.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

The configuration of the equipment will be described with reference to FIG. 1
Is the wind path. Inside the air passage 1, there are provided an adsorbing section 4 composed of an adsorbent 2 and a heating source 3, and a blower 5 capable of sending air to the adsorbing section 4 in the forward and reverse directions. A first communication port 6 is provided at the upper end of the air passage 1, and a second communication port 7 is provided at the lower end of the air passage 1. The control circuit 8 controls the operation of the heating source 3 and the blower 5.

The configuration of the control circuit 8 will be described with reference to FIG. The control circuit 8 is composed of a main control circuit 21, a drying circuit 22 and a desorption circuit 23. The drying circuit 22 is a blower first operation circuit 24 that controls the operation of the blower 5 and a heating source first operation circuit 25 that controls the operation of the heating source 3 and a dryer that controls the blower first operation circuit 24 and the heating source first operation circuit 25. And a driving circuit 26. The desorption circuit 23 controls the blower second operation circuit 27 that controls the operation of the blower 5 and the heating source second operation circuit 28 that controls the operation of the heating source 3 and the blower second operation circuit 27 and the heating source second operation circuit 28. The desorption operation circuit 29. The main control circuit 21 includes an operation circuit 30 that controls the drying operation circuit 26 and the desorption operation circuit 29, and a timer circuit 31 that issues a signal at predetermined time intervals.

The operation of the above configuration will be described. When the main power source (not shown) is turned on, the operation circuit 30 sends a signal to the desorption operation circuit 29 to rotate the blower 5 in the reverse direction and energize the heating source 3 to generate heat. The air 10 is supplied from the second communication port 7 and becomes warm air in the heating source 3, and the moisture adsorbed on the adsorbent 2 is desorbed and exhausted from the first communication port 6. After the adsorbent 2 is dried by the desorption operation and desorbed for a predetermined time by the timer circuit 31, the blower 5 and the heating source 3 are weakly operated by the blower second operation circuit 27 and the heating source second operation circuit 28, The adsorbent 2 is preheated and continues in a standby state in which it remains dry.

When an operation switch (not shown) is turned on in the standby state, the operation circuit 30 sends a signal to the drying operation circuit 26 to rotate the blower 5 in the forward direction and energize the heating source 3 to generate heat. The air 9 is supplied from the first communication port 6,
After the moisture content is removed by the adsorbent 2, it is heated by the heating source 3 and blown out as hot air from the second communication port 7. This blown air is a dry air that not only raises the temperature but also does not contain moisture, so that when it comes into contact with the material to be dried, the moisture can be removed and dried more quickly than with conventional means.

When the operation is stopped, the operation circuit 30 sends a signal to the desorption circuit 29, performs the desorption operation as described above, desorbs and dries the adsorbent 2, and enters the standby state again.

[0014]

As described above, the dryer of the present invention is
Since the blown-out air is a dry air that does not only increase the temperature but also does not contain moisture, the moisture can be removed and dried more quickly than the conventional means when it comes into contact with an object to be dried.
