[Detailed description of the device]

The present invention is an air circulation type heating device which is the gist of the "space body device for heating or heat retention" of the publication number 2747, No. 2747, which was filed by the applicant of the present invention and has been registered as a utility model. Concerning the structural improvement of.

[Industrial applications]

That is, this technical idea is based on two directions such as a hot air bathroom, a drying cabinet, a space body mainly for heating or heat retention, or a vertical and horizontal direction or a vertical direction, which is a main part of a box-shaped heating blower. At the same time, the circulation type air heating device including the heating air delivery system is a newly developed improvement for the purpose of responding to handling needs mainly for labor saving of maintenance such as repair and inspection and simplification of technology, and production of new device It is a novel technical idea that contributes to labor saving in stages and advanced quality control.

[Prior art]

An example of a conventional technique will be described with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing an outline of a heating mechanism of a hot air bathroom according to an embodiment based on the utility model. The main body (1) of a circulation type air heating device is placed diagonally across both a wall and a floor surface.
That is, a heating air passage is provided, a motor (5) is attached to the outside of the heating air passage, the rotary shaft of the motor is inserted into the air passage, and a fan (indicated by a dotted line) is locked on the shaft so that a heater (10) is provided above and below the air passage. ) (10 ') and the lid (2) with the air suction port (11) is attached to the upper surface of the flow path body to assemble the parts sequentially, as shown by the solid arrow (a). The ambient air is sucked in and kinetic energy is given by a fan and thermal energy is given by a heater, and a hot air flow in both the upper and lower directions as shown by the double-lined arrow (b) is provided as the outlet (1
2) The data is continuously transmitted from (12 ').

In such a case, it is functionally unfavorable for the motor to operate in a high temperature atmosphere, so that the fan should be located in the air flow path in the main body while the motor is located outside the main body as if it were located outside the main body. That is, the bottom plate (1 ') of the main body is sandwiched so that it is positioned on the opposite side of the fan, and the fan is pivotally supported on the rotary shaft of the motor protruding into the flow path. That is, the body bottom plate (1 '), which is the core of the circulation device structure, is used as the substrate, and the motor (5) is first screwed to the side without hot air on one side, that is, the lower side of the body in the figure, and then the opposite. The fan (3) is assembled on the rotary flow path side where high temperature air exists on the surface by a "component sequential assembly system" in which the fan (3) is locked on the rotary shaft.

[Problems to be solved by the device]

When the circulation type air heating device is used for the above purpose and usage, the influence of heat generated by the device accumulates on the rotary bearing portion of the motor, and eventually the oil runs out and wear occurs. Noise is generated and rotation is hindered, and maintenance or inspection or repair or replacement is required. In such a case, remove this lid from the place where the heat source is installed in the space to be heated or kept warm (Fig. 2), and attach the lid (2) mounting screw. 7th
As shown in the figure, loosen the fixing pin (3B) on the side of the central boss (3A) of the fan (so-called sirocco type) (3) and remove it to the upper part of the figure. And the metal fittings (6) are uncoupled, the combination of the motor (5) and the self-cooling fan (13) is attached to the outside of the main body of the device, that is, the lower side of the main body in the figure, and then the motor is cleaned or replaced. After that, the circulating air heating device is assembled in the reverse order and fixedly installed at a predetermined position.

Further, during the above-mentioned work operation, it is necessary to remove the electric wire for supplying electricity and the like from the relay terminal board for each heating device and to attach it. Generally, the installation place is narrow, or two or more heating devices are operated in parallel in many cases, and the troublesomeness is considerably serious. b. The fan fixing shaft (3B) is provided in the direction perpendicular to the rotating shaft (4), and its operation must be performed with an elongated hexagonal spanner inserted through a slight gap between the blades of the sirocco type fan. Is surrounded by air guides (9) and heaters (10), (10 '), etc., and it is difficult to work on site due to its narrow space. In addition, there are many cases in which the fan boss and the rotary shaft cause seizure. Handling techniques are required. If such a seizure of the rotating shaft and the fan causes seizure, and if it is difficult to remove it, forcibly disengaging it causes the fan to be distorted, causing distortion and unstable rotation during reassembly, and Problems such as difficulty in adjustment are likely to occur. The inspection, repair, and replacement of the motor inevitably require a certain degree of skill, and in addition to the time and troublesome crying.

[Means for Solving Problems]

The measures to be solved are (1) Do not remove the circulation heating device from the installation site. (2) Since the lid of the heating device is on the front side and can be easily removed, the motor can be replaced without removing the fan. For the purpose of labor saving and prevention of troubles, etc., the configuration was improved and the creation of a new technical idea such as this case was brought to fruition.

It is fixed to the same plate by coupling with the set metal fitting (6), and the fan (3) is fitted on the other surface of the fixing plate, that is, the upper end of the rotating shaft (4) projecting upward in the drawing, to fix the fan (3B). ) Is connected and pivotally supported on the rotating shaft, and three peripheral devices such as a fan, a fixed plate, and a motor are integrated to independently process, move, store, etc. as shown in FIG. Unit type "electric fan assembly composition" article group that can Put formed and on. In addition, this fixing plate needs to have a flat portion in contact with the fan, but the shape of the remaining portion is not specified.

On the other hand, an appropriate size of "passing gear" through which the motor (5) can easily pass in and out in the middle of the portion of the bottom plate (1 ') of the apparatus body (1) which becomes the heated air flow path (or in the lid). A hole "(16) is specially provided. A series of air flow passages are formed by the "air passage structure with passage hole", that is, the device body, the lid (2) with the suction port (11) (or the "cover with passage hole" and the "body"). The heater (10) (10 ') of the electric heating mechanism is attached therein to form a "fluid-equipped apparatus main body assembly constituent" article group as a stationary fixed part peripheral device in the same manner as the above. Prepare and put it down.

The motor of the "electric fan assembly component" article group is moved to the outside of the air channel by passing through a "drilling hole" specially provided in the apparatus body (or lid) of the "device assembly assembly with flow channel" article group. The mounting fixing plate (14) in the latter group of articles is placed on the bottom plate of the air channel in the former group of articles so that the fan is placed in the air channel and the screw holes (15A) of both are placed.

[Effect of device]

As described above, the fan is connected by sandwiching the bottom plate on the rotary shaft in the heating air flow path of the motor, which is directly fixed to the main body bottom plate (1 ') by "screws". The general "parts sequential assembly method" with the above configuration is abolished, and the newly installed "mounting and fixing plate" is used as a substrate to connect the motor and fan to enable independent storage of an independent unit type "electric fan assembly configuration" Primarily formed by placing a group of articles,
"Multiple article group combination" in which both article groups are secondarily combined in such a manner that "motor" and "fan" are arranged at predetermined positions by utilizing special "drilling holes" in the flow path structure. A) The system has been improved by using the "system" to achieve the simplification of the technology so that even non-experts can easily perform maintenance work such as inspection, repair, and replacement of the motor that involves attaching and detaching the fan. did it. That is, instead of a skilled worker, this "composition"
It can be completed easily by exchanging according to the "manual". (B) It is possible to maintain the function and improve the usability of the heat source device of the space body for heating or heat retention, which is often installed in a narrow place, by perfecting its maintenance. C. Even in the new production of the air circulation heating device, by assembling and adjusting the "rotating part related equipment" and the members having different properties from the structural parts such as the device main body are separately manufactured by separate dedicated lines. Labor saving of work process and efficiency of quality control can be achieved, and there are great social and economic merits of quality improvement and cost reduction. The effect is remarkable, and it is equivalent to the creation of a useful "new technical idea" related to "structure or combination of articles" in Articles 3 and 2 of the Utility Model Law, and is a great idea that contributes to the people's lives.
