Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a food waste storage cabinet, and more specifically, to a food waste storage cabinet in which food waste is thrown from the indoor side over the outer wall into a storage case on the outdoor side. It is.

[Prior Art] In recent years, various types of garbage storages have been proposed in which garbage generated in kitchens and the like is put into an outdoor storage case through an input port in an outer wall. By the way, when the lid of the input port for putting food waste in this type of food waste storage is opened, the odor of the food waste inside the outdoor storage case leaks into the room and the odor wafts inside.
As in Japanese Patent No. 151444, it has been proposed that a storage case is provided with a ventilation fan, and when the lid of the input port is opened, the ventilation fan is driven in conjunction with this.

[Problems to be solved by the invention] By the way, in conventional devices in which a ventilation fan is driven when the lid of the input port is opened, the lid of the input port is easily set to the fully open state. Therefore, when quickly opening the lid fully,
The ventilation fan, which is driven in conjunction with the lid opening operation, does not reach full rotation immediately after startup, but reaches full rotation after a certain startup time has elapsed. There was a problem that the ventilation fan did not rotate sufficiently, causing odor to leak into the room.

[Means for solving the problem] In order to solve such problems, the present invention
A normally closed push switch SW and a roller catch 24 for stopping and driving the ventilation fan 3 are provided on the rim of the inlet 4 on the indoor side.
A lock projection 23 having a groove thereon is provided on the lid 5, and this lock projection 23 is press-inserted into the roller catch 24 so as to be releasable in two stages, and a first claw 25 at the tip of the lock projection 23 presses the pressing portion 22 of the push switch SW.

[Function] In the present invention, a normally closed push switch SW for stopping the ventilation fan 3 and a roller catch 24 are provided on the rim of the indoor side of the inlet 4,
and a lock protrusion 23 provided with a second pawl 25 and 26.
is provided on the lid 5, the second claw on the base side is press-fitted into the roller catch 24, and the first claw on the tip is pressed into the roller catch 24.
To open the lid 5 from the fully closed state where the claw 25 presses the pressing part 22 of the push switch SW, the second claw 26 on the base side is removed from the roller catch 24 and the first one is removed from the tip of the push switch SW.
When the claw 25 is separated and the ventilation fan 3 is driven, the first claw 25 on the lid 5 side is still held by the roller catch 24, and while the ventilation fan 3 is being driven in this way, the lid 5 is In this way, the lid 5 can be held in a position close to the fully closed state, and the lid 5 can be held in the initial stage of the opening operation when the lid 5 is slightly opened from the fully closed state, and the ventilation fan 3 can be driven in this held state, and thereafter. When the lid 5 is opened, odor is prevented from entering the room.

[Example] The present invention will be described in detail below with reference to the accompanying drawings. 1 is an outer wall, and a storage case 2 is attached to the indoor side of the outer wall 1. There is a garbage container 6 inside the storage case 2.
The storage case 2 has a front opening 7 provided with a door 8 that can be opened and closed. A ceiling plate 10 is arranged below the top plate 9 of the storage case 2 substantially parallel to the top plate 9, and an exhaust passage 11 is formed between the top plate 9 and the ceiling plate 10. A ventilation fan 3 is provided approximately in the center of the ceiling board 10, and the ventilation fan 3 guides odor from above the garbage receiving container 6 into the exhaust passage 11. An exhaust port 12 is provided in a portion of the exhaust passage 11 facing the upper end of the door 8.
A recess 13 for attaching a deodorizer is provided near the exhaust port 12, and a deodorizer 14 is removably mounted in the recess 13. 15 is an air inlet provided at the lower end of the door 8. A through hole 16 that communicates with the inside of the storage case 2 is bored in the outer wall 1, and an input opening 4 is formed by inserting a rectangular input cylinder 17 into the through hole 16. The flange 18 on the indoor side of the cylinder 17 is in contact with the edge of the through hole 16. A rectangular frame-shaped lid receiving plate 19 is arranged so as to cover the edge of the through hole 16 on the indoor side, and is attached with a fastener such as a wood screw. A lid 5 for opening and closing the input port 4 is attached to the lid receiving plate 19 so as to be openable and closable using a hinge 20.
A switch housing 21 is attached to the input cylinder 17 on the indoor side between the through hole 16 and the input cylinder 17, and a push switch SW is attached to the switch housing 21. This push switch
The SW is a normally closed switch that is turned off when the pressing part 22 is pressed and turned on when the pressing part 22 is stopped. On the other hand, a lock protrusion 23 is provided on the lid 5 corresponding to the pressing portion 22 of the push switch SW, and the lid 5
In the closed state, the pusher switch SW is turned off by pressing the pressing portion 22. In addition, the switch housing 21 has a roller catch 2 as shown in FIG.
4 is provided. Here, the lock protrusion 23 has first and second pawls 25 and 26 formed in a bulging manner.
When the lid 5 is closed, the second pawl 26 is held by the roller catch 24, and the first pawl 25 presses the pressing portion 22. 27 is a handle of the lid 5.

However, when the lid 5 is closed, the push switch SW is turned off and the ventilation fan 3 is stopped. In order to open the lid 5 and throw in food waste, when you hold the handle 27 and open the lid 5, the second claw 26 is first unlocked from the state shown in Figure 3, and as shown in Figure 4. Then, the first pawl 25 shifts to a locked state. At this time, the first claw 25 is removed from the pressing portion 22, the push switch SW is turned on, and the ventilation fan 3 is started. When the lid 5 is further pulled, the first claw 25 is also unlocked and the lid 5 opens, but at this time the ventilation fan 3 is already in full operation.

[Effects of the invention] As described above, the invention provides a normally closed push switch and a roller catch for stopping the ventilation fan on the rim of the indoor side of the inlet, and a locking protrusion with first and second claws is attached to the lid. Since the second claw on the base side of the lock protrusion is press-fitted into the roller catch, and the first claw at the tip presses the pressing part of the push switch to open the lid from the fully closed state, it is necessary to open the lid from the fully closed state. When the second pawl is removed from the roller catch and the first pawl is separated from the tip of the push switch to drive the ventilation fan, the first pawl on the lid side is still held by the roller catch,
In this way, the lid can be held in a position close to the fully closed state while the ventilation fan is being driven, and in this way, the lid can be held at the beginning of the opening operation when the lid is slightly opened from the fully closed state. There is an advantage that the ventilation fan can be driven in such a held state and that odor can be prevented from entering the room when the lid is subsequently opened.
