Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heater in which a device main body is provided with an exhaust port for discharging hot air from an internal heat source, and a lid is provided to allow the exhaust port to be opened and closed.

Conventionally, in this type of heater, the heat source operator was locked in an inoperative position when the exhaust port was closed to prevent the heat source from being accidentally activated with the exhaust port closed by the lid. Although it is known,
(No. 4722 Publication), if you leave the exhaust port open, the controls will become unlocked and move when you touch them carelessly, or as a result of a child's mischief. Therefore, it is desirable to take child-proof measures to prevent this.

The present invention has been proposed to meet such demands, and includes forming an exhaust port 3 in the appliance body 1 for discharging hot air from an internal heat source 2;
In a device provided with a lid body 4 that can be opened and closed freely,
A door 6 that can be opened and closed and covers the arrangement part of the operator 5 of the heat source 2 is attached to the side surface of the device main body 1, and a shaft 6a is attached to the upper side of the door 6.
The lid body 4 is pivotally supported in an upward-opening manner.
A locking mechanism 7 is provided which locks the door 6 in the closed position in conjunction with the opening/closing operation of the door 6 when the door 6 closes.

Figures 1 to 3 show a gas brazier as a heater, and the brazier has a heat source 2 consisting of a gas burner in a housing-shaped appliance main body 1 having an exhaust port 3 on the top surface and facing the exhaust port 3. The exhaust port 3 can be opened and closed by a lid 4 detachably placed thereon, and when not used as a brazier, the exhaust port 3 can be closed with the lid 4 and used as a stand.

and an operator 5 of the heat source 2 consisting of a kettle pick.
is housed in the instrument main body 1 facing the operation window 8 on the side, and the operation window 8 is provided with the door 6 which can be opened and closed as described above. Further, the lock mechanism 7 described above is
A lock piece 1 that can be raised and lowered is biased upward by a spring 9.
0, and a locking hole 11 in the side frame of the door 6 through which the bent portion 10a at the lower end of the lock piece 10 is inserted, and the locking hole 11 is longitudinal in the vertical direction and has a locking hole 11 at the upper end. The locking piece 10 is provided with an escape groove 11a for releasing the engagement with the bent part 10a, and the locking piece 10 has its upper end 10b inserted into a through hole 12 formed at the opening edge of the exhaust port 3 that supports the lid 4. I decided to have him present.

In the drawings, reference numeral 13 indicates a drawer for storing small items provided on the side of the main body 1 of the instrument.

Next, the operation will be explained. According to the closing operation of the lid 4, the lid 4 closes the upper end 10 of the lock piece 10.
b, the lock piece 10 contacts the spring 9 and moves downward, and the bent part 10a engages with the locking hole 11.
The door 6 is locked in the closed position, but when the lid 4 is opened, the lock piece 10 is released from the downward pressing force of the lid 4 and moves upward by the spring 9. The curved portion 10a faces the relief groove 11a, the door 6 is unlocked, and the door 6 can be opened to perform ignition operation using the operator 5.

After use, return the operator 5 to the "stop" position and close the door 6.
Close the door 6 to prevent the operator 5 from being moved carelessly due to a child's mischief, etc. In this case, close the door 6.
If the door 6 is made to open upward, the door 6 will automatically close due to its own weight, which is advantageous in terms of child proofing since it will not be forgotten to close.

In the above embodiment, ignition operation with the exhaust port 3 closed is prevented, but to further improve safety, it is possible to prevent the exhaust port 3 from being accidentally closed with the lid 4 during ignition operation. It is desirable to be able to notify the user that ignition is in progress when attempting to do so.

FIGS. 4 to 6 show an embodiment that satisfies such demands, and detects the rotational position of the operator 5 on the door 6, and when the operating element 5 is not returned to the "stop" position, the door 6 is placed under the locking piece 10. A lock lever 14 is provided which operates to prevent movement.

To explain this in more detail, the lock lever 14 is:
The operating portion 14a at one end thereof is pivotably supported in an operating position facing the locking hole 11 and an inoperative position in front thereof, and is normally biased to the inoperative position by a spring 15. , when the operator 5 is returned to the "stop" position, the lock lever 14 is held in the inoperative position even if the door 6 is closed, but if the operator 5 is returned to the "stop" position If not, when the door 6 is closed, the detection portion 14b extending behind the other end of the lock lever 14 comes into contact with the grip protrusion 5a on the front surface of the operator 5, and the lock lever 14 is pressed against the spring 15.
The bent portion 10a of the lock piece 10 that is inserted into the locking hole 11 comes into contact with the operating portion 14a of the lock lever 14 and is prevented from moving downward, and the lock piece The upper end 10b of the lid 10 is locked in a state protruding upward from the above-mentioned through hole 12, thereby preventing the closing operation of the lid 4, thereby informing the user that ignition is in progress.

In the drawing, reference numeral 16 indicates a stopper of the lock lever 14.

In the above embodiment, a gas burner was used as the heat source 2, but the present invention is not limited to this, and an electric heater may also be used.

In this way, according to the present invention, a door 6 which can be opened and closed and which covers the arrangement part of the operator 5 of the heat source 2 is supported on the side surface of the main body 1 of the apparatus in an upward-opening manner by the shaft 6a at the upper end thereof. Since the door 6 is provided, the door 6 can be closed freely.
This prevents the user from forgetting to close the door 6, and therefore, when the cover 4 is next applied to the exhaust port 3, the door 6 can be locked in the closed position by the locking mechanism 7 that is linked to this closing operation. As a result, the operator 5 cannot be touched when the lid 4 is attached, and as a result, the operator 5 may be operated with the lid 4 attached, and the operator 5 may be damaged or operated incorrectly. This has the effect of completely eliminating the inconvenience of the heat source 2 being activated by the operation of the child 5.
