Abstract

PURPOSE:To improve cleaning workability by a method wherein the power line of a blower motor is automatically turned OFF when a hood front plate is dismounted from the front opening of the hood main body of a range hood fan. CONSTITUTION:A hood front plate 17 and a pugh-off type switch are provided on a hood main body 1, near the front opening of which a lever 30 energized so as to puch the operator 24 of the switch at all times is pivotally provided. An engaging part 33, which is engageable with a part to be engaged 21 of the hood front plate 17 is formed on the lever 30. When the engaging part 33 and the part to be engaged 21 are in engagement, the lever 30 and the hood front plate 17 interlock so that the pressing and release of pressing of the operator 24 of the switch is performed in accordance with the mounting and dismounting of the hood front plate 17. When the hood front plate 17 is dismounted from the front opening of the hood main body 1, the operator 24 of the switch is pressed by the lever 30, resulting in automatically turning the switch OFF. Consequently, no pulling of the plug of a power cable out of a power plug receptacle is necessary when the cleaning of the hood main body is performed.

に[Field of the Invention] The present invention provides a rotating +il fi
ii, I: One removable hood iii: + board,
(i2 F, c ventilation) Relates to ventilation. (Technical cost of the invention) Conventionally, ventilation devices called range hood fans have been
3 (between 1q side and t side 1.
/A blower, such as a ventilation fan, is installed on the main body of the hood, and in order to open and close it between part 1 and 1 of the front of the main body, rotate the front plate. (According to μ theory, in history, when the upper surface of the node main body is opened [A when the operation j'- is pressed near the first part), the energizing path of the motor of the ventilation fan is cut off. Switch J
- is installed on the front board of the hood next to INJ g 115 on the front board of the node. Turn off the energized circuit, release the pressure on the switch 1'+- of the hood with a tenon on the open surface of the node front plate, and remove the switch. In the conventional 414 configuration, the front frontage is reduced by 1.1 mm in order to reduce the inside of the hood body. When removing the hood plate from the hood front plate, press 1] - of the switch operator by the hood front plate is released.
This is extremely dangerous as it can turn off the power supply and cause the ventilation fan to become energized overnight, so when cleaning, It is necessary to pull it out from the power outlet I- and put it in place.
'i! Contains non-molluscs that are difficult to remove. Also, it is conceivable to place another switch in the energized path of the shutter that can be operated manually to turn on and off the valve, but this would result in an extra switch being used. There is a 4. problem with the C-1 store tab. (Objective of the Invention) Kokumei made C in view of the circumstances in item 11, and the purpose (41. When it is removed, it is possible to automatically turn on the switch for the Tanabata passage of one feeder, so that the cleaning work efficiency is reduced and there is no loss (~P). (Summary of the Invention) The present invention provides a node front plate and a bussine type switch on the hood body to reduce the odor C1 of the hood front plate. Form an engaged part in the above-mentioned No. 1~ Always near the front opening of the main body) Operation of the J switch The lever is provided with an engaging part that can be engaged with the engaged part of the front plate of the hood, and when engaged with the engaged part of the front plate of the hood.

When the hood front plate 17 is mounted on the support piece 4.1 of the hood main body 1, the support J'+20.20 of the hood front plate 17 is fitted from above to support it, and then Screw the front ends of the pull lock levers 39, 39 to the cock mechanisms 38 and 38. Then, as the hood front plate 17 is rotated in the direction of arrow CIi, which is the closing direction, the engaged member 21 The engaged protruding piece 22 presses the outer surface of the arc-shaped hook portion 35 of the engaging member 33, and as a result, the engaging member 33 is pressed against the tension coil spring 3G. When the engaging member 33 is rotated in the direction of the arrow B and the opposite direction of the arrow Ij against the spring force of the engaging member 33 L, L tension coil spring The knock part 3 is rotated by the spring force of 36 in the direction of arrow 137J.

Ventilation operation is started one day later. Furthermore, when the node front plate 17 is rotated in the direction opposite to the direction of arrow C at an angle 31, the locking mechanism 38.38M causes the hood front plate 1t to maintain its constant open angle position. [1] will be added to [1]. As a result, between the lower surface of the hood main body 1 that serves as the intake port [1 part is the part where the hood front plate 17 is opened (there is a part C that becomes closed).When stopping the ventilation operation, the hood front plate 17 Once the turning force in the closing direction (arrow C direction) is
After applying the turning force in the opening direction (the direction of arrow C is the opposite direction), fj+ is applied again.
Therefore, if the hood front plate 17 is rotated again in the closing direction, it will return to the closed state shown in FIG. 1, and the switch 25 will turn Δ
The electric current path of the motor 8 of the ventilation fan 5 is damaged. On the other hand, in order to remove the inside of the hood body 1 by 11'il, the node front plate 17 is not removed from the 11 part between the front surfaces of the hood body 1. 15]. 19 without removing r=I screw 41.

For example, if J is used, then the following J: B is the effect of the Song and Qin Dynasties. That is, the lever that presses the pressing protrusion 32 that presses the handle 1 and 2'l of Suin J-2!5. The hook part 335 of this retaining member 33 is engaged with the engaged part 22 of the engaged member 21 of the hood front plate 17. (Therefore, the lever 30 can be moved to the hood front plate 17).The hood front plate 17 can be closed and the lever 3''30 can be pressed in response to the operation 1'. When the piece 32 presses and releases the pressure 34 against the operator 24 of the soup cup 25, the hood front plate 17 is removed from the front part 1 of the hood main body 1. At this time, the engagement between the joint part 22 and the knock part 35 of the cover 1 system is automatically released and the pressing protrusion 32 of the C lever 30 presses the 1!

The 171 part between the front surfaces of the hood body 1 protrudes toward the horn.
The thing is 4I: <, therefore, when performing C11, 11 division, there is no possibility that a human body, object, etc. will accidentally collide with the operator 24 of the switch 25 and the C switch 25 will be damaged by 1 (1). Fig. 4 shows a second embodiment of the present invention, which differs from the previous embodiment (instead of the pull cord 37, a manual operation member is used to release the part IJ/I2, which is located at the Iζ point. The member 712 is installed in the guide bin 43 on the back side of the hood front plate 17 so as to be able to move downward, and is always moved to the upper blade by the spring force of the tension spring 44. Furthermore, a release protrusion 45 corresponding to the hook portion 35 of the engagement member 33 is provided at the upper end of the release member 42 in a 11-piece pattern. ,
The upper end of the release member 42 is connected to the upper end of the release member 42 (, - is connected to the upper end of the M soi 1 174G, and the lower end of the side plate 19 is connected to the upper end of the Therefore, the locking member 47 is connected to the 1 parking part 4Δ/!7.
In particular, J, through the connecting wire 1746, "CW (pulling the removed part 7' I2) spring force kX of Ilpone 4/l resists 1・J'r L2 movement, and release. The protrusion 45 engages with the hook portion 35 and pulls the engagement member 33, causing it to rotate in the direction opposite to the direction of arrow B against the force. Therefore, the engagement of the knock portion 35 with the engaged protrusion portion 22 is removed by M7. In the example of 2, J, -) (the above example/

When operated in the direction, the engaging portion 33 pulls the spring 3
The knock portion 35 is rotated in the direction opposite to the direction of the arrow B against the spring force of 6.
In this third embodiment, the effect of the first implementation limit 4X can be obtained. In the above-mentioned embodiment 'C-', one tension spring 36 is configured to force the lever 30 to rotate in the direction of the arrow Δh and to urge the engaging member 33 to rotate in the direction of the arrow B.
