Abstract

PURPOSE:To improve properties of design and assemblage and provide the circulator, prominent in performance also, by a method wherein the main body of circulator is constituted of a front section, a rear case holding fans, a switch case encasing electric parts and a rear cover holding the switch case. CONSTITUTION:The main body 1 is separated into the front section 2, the rear case 3, the switch case 3 and the rear cover from functional aspect. According to this method, not only the management of components is very clear but also the property of assemblage is very good such that the wiring between the switch case 4 and a motor 16 can be effected through connectors 37, for example. Centrifugal fans 6 are covered by a front case 2, therefore, the constitution of the circulator is prominent in design also. The upper part of a filter is constituted of a screen while the lower part thereof is constituted of slit-like holes, therefore, the suction stream of air shows a frequency characteristic having no turbulence such as pulsation or the like. Further, indoor convection is effected smoothly from the opening of the circulator during a time from ignition to the point of ON of a stove, therefore, the practicality of the circulator is very high.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a circulator, and particularly to a circulator with improved assemblability and followability of a thermostat. .

[Background of the invention]

Conventionally, the configuration includes a filter.

For example, as shown in Japanese Utility Model Application Publication No. 60-10136, a configuration is known in which filters are installed on the top surfaces of four bodies and one body is formed vertically into a box shape, but this is not only difficult to assemble, but also has problems with thermostats. It had the drawbacks of poor air permeability and lack of followability.

[Purpose of the invention]

The purpose of the present invention is to functionally configure one main body into four blocks to improve design and ease of assembly.

A filter structure that effectively utilizes the characteristics of a once-through fan.

Our goal is to install a thermostat and provide a circulator with excellent performance.

[Summary of the invention]

The present invention greatly improves ease of assembly by forming a main body from a front part, a rear case holding a blower, a switch case part storing electrical parts, and a part of a back cover holding this switch case part. It is.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

1 is the main body, 2 is the front case, 3 is the cow case, 4 is the switch case, 5 is the mounting hook, 6 is the j
8 is a pilot lamp cover, 9 is a "manual-automatic" changeover switch, 10 is a degree adjustment knob that adjusts the temperature sensed by thermostat 10, and electrically the second
The circuit is configured as shown in the figure, and has 11 pull-string switches 11.
By operating the pull string 111, you can set it to "off - strong and weak"! @Start and stop machine 16.

The casing 18 has screws 2 on the inner surface of the front case 2.
0, and is fixed to the screw boss portion 2b of No. 2. A chain side hook 19 is inserted into 18a of 18 by pushing it.

7 is a flapper that changes the direction of the discharged air.

In order to stop and hold it midway, a rubber support 7 is provided on the outer periphery of the shaft of 7, and as shown in Figure 3, if you use the protrusions 18C for lowering 7 and 18, you can move it to the 7' part for summer use. .

Careful consideration has been given to the stoppers 18b and 3f to prevent them from coming into contact with the cross-flow fan 6 even if 7 is operated incorrectly by the customer.

2 and 3 are fixed together by providing hooking protrusions 3a at four places on the upper surface of 3 and hooking them on the protrusions 2C of 2, and the lower surface is attached to the screw boss part 2 of 2.
It is fixed to C with screws 21.

Between 2 and 3, there is a blower section configured as shown in FIG.
7 pin, 5a is the boss part for fitting to 27.30, 31 is the boss part for fitting to 6
It is fixed to 6 with a screw 32 using a holding metal fitting.

31 is fixed to 3 using the screw boss portion 3b of 3.

3C with screws 33.

Reference numeral 22 denotes a switch case, which includes the string-type switch 11 for electrical components shown in FIG. 2, the pilot lamp 12, and the starting capacitor 15. @ Sound prevention capacitor 14, "Manual - Automatic"
Changeover switch 9. When storing the thermostat 10 and assembling the thermostat 2, the work is completed by simply connecting the connectors 6 and 13 with the connector 37.

To fix 22 to 3, push the convex part 22a of 22 into the insertion ring 3e of 3, press the back cover 23 from the rear surface of 22, insert the claw part 23b of 23 into the square hole 3g of 3, and tighten the screw. 25 should be fixed in one place to the screw boss hole 3h of 3.

As shown in FIG. 6, a filter 26 is inserted into the back of the unit 3 to prevent line dust from spreading into the room.

26 is formed by a frame 26 around one side, and a filter 260. The lower part has a slit-like hole 26b attached thereto to prevent vibration during vibration.

A convex portion 26e is provided for attachment to 3, and a finger insertion portion 26a is provided for removal.

〔Effect of the invention〕

According to the present invention configured as described above, the six main body parts are a front part, a cow case part, and a switch case part.

Since the back cover is functionally separated, management is not only very clear, but the switch case part where electrical parts are housed and the motor part can be connected with the connector 37, making it extremely easy to assemble. Since the front case covers the cross-flow fan 6, it has an excellent design.

In addition, since the filter 26 has a cross-hole in the upper part and a slit-like hole in the lower part, the intake air flow generated by the vortex 34 generated near the tip part 3d, which is a characteristic of the cross-flow fan 6, is 3.
As shown in Figure 6, there is a strong characteristic in the perpendicular direction, but since the configuration makes full use of this characteristic, it shows a frequency characteristic with no sagging such as pulsation as shown in Figure 7, and furthermore, the motor side of b in Figure 4 is Since the thermostat is installed in the area 36 where the ventilation flow is most likely to flow, the characteristic after extinguishing the stove is 39 compared to the characteristic 40 of the conventional structure, as shown in Fig. 8. It is extremely excellent.

Furthermore, the time from ignition of the stove to the ON point.

Since the indoor convection can be carried out smoothly through the openings 22C and 23a, a highly practical circulator such as 39 can be provided.
