The present invention allows the temperature of the enclosed hollow room to rise by the frictional heat obtained by promoting friction with air while maintaining the room under reduced pressure by the rotational action of the rotating body, and simultaneously The present invention relates to a pressure reducing equilibrium heating apparatus configured to be dried effectively by a synergistic effect between a depressurizing action and a heating action due to a rotating action of a rotating body.

Conventionally, in order to heat a hollow room, the heat source was necessarily necessarily required, for example, to supply a hot air or to use a heating heater. In particular, the hollow chamber in which the dry items are stored required a blow pump for blowing air and a heat source such as petroleum, gas, or heater to obtain necessary heating air.

Therefore, in the heating apparatus for the purpose of drying, effective energy utilization such as the need for a heat energy source for obtaining heating air besides the energy for blowing air is not made, and energy such as petroleum or gas supplies the pump or the heating apparatus. There were irrationalities such as needlessly consumed large quantities to drive.

An object of the present invention is to solve the drawbacks described above, and the suction pressure reduction action due to the rotational action of the rotating body and the energy for blowing the air without using a special heat source for obtaining heat energy for the sealed hollow chamber and its Decompression maintained

In this way, various dry items such as agricultural and marine products or clothing stored in the hollow chamber can be dried efficiently and quickly by the depressurizing effect and the friction effect.

Another object of the present invention is to generate a rotational force in the intake action of the outside air, by rotating the rotating air conveyer by this rotational force to reduce the temperature distribution in the hollow chamber to achieve a uniform drying action To provide.

Another object of the present invention is to prevent the temperature drop in the hollow chamber by preheating the outside air cooled by the auxiliary heating device on the basis of the suction of the outside air, and the heating device is automatically connected with the temperature conditions in the hollow chamber. It is to provide a reduced pressure balancing heater configured to perform a heating operation manually or manually.

Other objects, features and advantages of the present invention will become more apparent from the following description.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the device according to the present invention.

First, the configuration of FIG. 1 will be described. The hollow chamber 1 having a rectangular parallelepiped shape is sealed by a pair of doors 2 having an openable structure, and an insulating material 3 is interposed between the upper and lower outer walls 3a. It is fitted in and can keep warm. In the suction port 4 opened in the ceiling center of the hollow chamber 1, the rotating body a is arrange | positioned so that it may rotate freely. This rotor (a)

And the frictional heat generation part A is formed in the rotation area | region of the rotating body a.

The outdoor air supply unit 7 for supplying the outdoor air to the hollow chamber 1 has one end 7b connected to the lower portion of the hollow chamber 1 and an end 7c opened to the bottom of the hollow chamber 1. The air supply pipe 7a is disposed below the bottom wall of the hollow chamber 1 having the legs 8.

A control valve 10 is provided on the open end side of the external air supply pipe 7a so that the flow rate of the outside air passing through the inside of the external air supply pipe 7a can be freely adjusted by the handle 10a. In addition, although the control valve 10 is not shown, it can be used as a general automatic control valve that can variably adjust the operating pressure conditions by the temperature difference in the hollow chamber 1 and the pressure inside and outside the hollow chamber 1, It can be automatically opened and closed in accordance with the temperature of the chamber 1 or the depressurized state to supply the outside air.

On the other hand, the door 2 is provided with the window 11 which can observe the inside of the hollow chamber 1, and the display panel 12 which instructs the temperature, pressure, etc. in the hollow chamber 1, and the like. The support cylinder 13 is for holding the electric motor 5, and has an exhaust passage 14, and a noise cylinder 15 for removing noise is provided at the open end thereof. In addition, although not shown in the hollow chamber (1), it is possible to arbitrarily install a shelf and a support frame for supporting the shelf, etc., all of which must have a configuration considering the ventilation effect.

Next, the operation in the above-described configuration will be described.

When the rotary blade 6 is rotated by supplying electric power to the electric motor 5, the air in the sealed hollow chamber 1 is gradually decompressed by the suction and exhaust action of the rotary blade 6, so that the inside and the outside of the hollow chamber 1 are reduced. The pressure difference becomes larger, but is almost equilibrated when a certain pressure difference is reached. The pressure difference inside and outside the hollow chamber 1 in this substantially constant equilibrium state is determined by the size of the rotational suction force of the rotary blade 6 and the gap size between the suction port 4 and the rotary blade 6, but the rotary blade 6 This equilibrium state is maintained as long as the rotation action of.

In this equilibrium state, air stays in the frictional heat generating portion A in the rotational region of the rotary blades 6, and frictional heat with the rotary blades 6 continues and the frictional heat is generated and the temperature gradually rises. Then, the frictional heat is sequentially transferred into the hollow chamber 1 to heat the room to a desired temperature.

Therefore, if the dry matter is accommodated in the hollow chamber 1, the glass properties of the dry matter can be improved by the depressurization action, and the free moisture of the dry matter is heated by heating to the dry matter by rising the room temperature. It is possible to promote the divergence of the membrane and to obtain a highly efficient drying effect.

In addition, when the control valve 10 is opened from the external air supply pipe 7a to supply external air in the course of the heating operation, the temperature in the hollow chamber 1 drops, but water vapor in the hollow chamber 1 is reduced by the amount of the supplied air. By being discharged to the outside by the rotary blades 6, it is possible to further promote the drying action.

The present invention, as described above, as a device for heat generation, as in the conventional heater

Next, the Example of FIG. 2 and FIG. 3 is demonstrated.

The difference between the embodiment shown in FIG. 1 and the embodiment shown in FIGS. 2 and 3 is in the configuration of the external air supply unit, and the others are all in the same technical configuration. The same configuration as the embodiment shown in FIG. 1 is denoted by the same reference numerals, and description thereof is omitted. That is, the outside air supply section 16 is arranged on the inner bottom surface of the hollow chamber 1 to provide an intake air inlet passage 17 with the inlet 16a open on the front surface thereof, and is introduced to the intake air inlet passage 17. The adjustment nozzle 19 which protruded the handle 18a to the front surface was provided in the front-end | tip of the pipe 18. As shown in FIG.

4 is a view showing another configuration of the outside air supply unit according to the above embodiment, wherein the introduction path 20c of the outside air supply unit 20 is detachably filled with a vibration suppression filter 21 to replace the outside air. It is a structure which can remove the dust etc. in it.

The outdoor air supply pipe 20b is directed to the inside of the hollow chamber 1 and communicates with the internal opening 20a. The outside air is supplied into the hollow chamber 1 by operating the valve 22 with the handle 22a.

Next, the embodiment shown in FIGS. 5 to 11 will be described. The basic configuration of this embodiment is the same as that of the above embodiment, but differs in that an external air supply unit, a flow rate adjusting mechanism, and the like are added. Since the same components as those of the above embodiment are denoted by the same reference numerals, the description thereof will be omitted.

The outside air supply section 25 is disposed below the hollow chamber 1, the outer end 25a of which is faced to the outside from the outer circumferential wall of the hollow chamber 1, and the inner end 25b is rotating air.

In addition, although not shown, the heater 30 may be automatically controlled to maintain a set room temperature at all times by a temperature controller or the like.

In addition, the control valve 31 can also be used as an automatic control valve that detects a temperature difference inside or outside the room and automatically opens and closes the valve instead of manual operation.

The slit-shaped opening 33 is formed on the stirring cylinder 32 of the radially projecting rotary air carrier 26, and the outside air which rotates the sirocco fan 27 to drive the perforated plate 34 is formed. After being fed into each stirring barrel 32, it can be discharged upward from the slit-shaped opening 33. A bearing 35 is provided between the rocking fan fan 27 and the shaft cylinder portion 28 of the rotary air feeder 26, and the air volume adjusting mechanism 36 is disposed above the rotary air feeder 26. The airflow control mechanism 36 is composed of a plurality of inclined plates 37 arranged in parallel and a gap g formed between adjacent inclined plates 37. The supplied heating air is moved through the gap g and in accordance with the inclination angle of the inclined plate 37 so that a uniform temperature distribution can be obtained in the room. In this case, the free end of the inclined plate 37 is raised upwards to automatically narrow the gap g so that the flow rate can be suppressed.

The porous plate 39 supported on the upper portion of the hollow chamber 1 serves to uniformly suck the air sucked by the suction-rotation action of the rotor a from the whole surface and is exposed to the rotor ( Shielding a) prevents the risk of handling.

Furthermore, although not shown in detail, the hollow chamber 1 may optionally include a shelf for placing the object and a supporting frame for supporting the shelf, all of which must have a configuration considering the ventilation effect.

Referring to the heating operation of the above embodiment.

Since the heating action in the hollow chamber 1 is performed by the suction decompression action and the friction action by the rotary blade 6, it is the same as the above-mentioned embodiment. In this embodiment, the outside air supply section 25 is operated after the temperature in the hollow chamber 1 reaches the desired set temperature. That is, when the control valve 31 is operated by the handle 31a to introduce the outside air into the outside air supply section 25, the outside air is auxiliaryly heated by the heater 30 and is equal to the temperature in the hollow chamber 1. Or at a temperature close to that, the air is fed into the hollow chamber 1.

In addition, the outside air heated by the rotating air conveying member 26 is fed in a rotating state and adjusted so that the temperature distribution is uniform by the airflow control mechanism 36 at all times, so that the object to be dried in the hollow chamber 1 is Even at all times it can receive a uniform drying action.

In this intake introduction path 41, a plurality of heaters 43 separated by a plurality of shield plates 42 are incorporated, so that the sucked outside air tends to stay on the heater 43 by the shield plate 42. The outside air is heated efficiently. The intake air intake passage 41 is connected to a conduit 44 which is connected to a vane cylinder 48 having a bearing cylinder 47 via an adjustment cock 45. Opening and closing of the adjustment cock 45 is performed by the operation of the handle 45a, and the bypass pipe 46 is arranged in parallel with the conduit 44.

In the vane cylinder 48, a rotating air conveyer 50 having a vane 54 is rotatably inserted. The slit 52 is provided along the upper edge of the radial inclined spreading blade 51 provided in the rotary air carrier 50, and the air heated from the slit 52 into the hollow chamber 1 is supplied. The temperature distribution inside the hollow chamber 1 is made uniform by discharging and assisting the rotation of the vanes 54 by the reaction to smoothly rotate the rotating air conveyer 50.

In addition, in the hollow chamber 1, not only the air volume control mechanism 36 shown in FIGS. 10 and 11, but also a plurality of porous shelves 60 are attached as shown in FIG.

It is possible to generate frictional heat by the friction action of the rotating body and air, and the hollow chamber can be heated by the temperature rise due to the frictional heat. Furthermore, after the temperature in the hollow chamber reaches the desired temperature, the outside air is supplied to the outside air heated to the desired temperature from the external air supply unit, thereby discharging the vapor content of the dry matter to the outside through the inlet port and preventing the temperature drop in the hollow chamber. The drying effect can be further increased.

In addition, since the air feeder is provided with a rotating air feeder, the feeder can be rotated during intake to uniformize the temperature distribution in the hollow chamber, so that the dried object can obtain a uniform drying effect at any position of the hollow chamber. .

As described above, the present invention omits the use of a direct heat source such as a heater or a fuel, and uses only a small heater that auxiliaryly heats the outside air as in the related art, thereby greatly reducing energy consumption. Therefore, various dry items such as agricultural and marine products or clothing contained in the hollow chamber are effectively and quickly dried.

Moreover, the hollow chamber itself is a heating source as the inside of the hollow chamber is filled with heating air, so that the heating air can be used for various heaters such as indoor warmers, water heaters, greenhouse heaters, and the like.
