This will be described in detail with reference to FIG. One or more open / close switches are provided, and a manual switch 45, a foot switch 4
6. It is composed of a non-contact switch 47 and the like. The open / close switches 45, 46, and 47 are all connected to a controller 57. The controller 57 is further connected to an actuator that rotationally drives the closing lid 12, and the actuator is a lid open / close motor 51 in this embodiment. However, it is also possible to use a cylinder or the like.

The manual switch 45 is provided with the closing lid 1.
It is arranged in the center of the left and right of the upper surface of the front of 2, and every time you press it,
This is a single push button type switch for both on and off, which switches between “on and off” corresponding to “open and close” of the input lid 12.
By pressing the manual switch 45, an open / close signal is transmitted to the controller 57, and the controller 57 drives the lid open / close motor 51 to rotate based on the open / close signal. The lid opening / closing motor 51 is provided inside the rear left upper portion of the garbage disposal machine 9. An opening / closing shaft 87 is connected to a rotating shaft extending rightward from the lid opening / closing motor 51. The rear edge of the loading lid 12 is pivotally supported by 87.

Alternatively, when the manual switch 45 on the closed lid 12 is pressed by using a part of a garbage can, the manual switch 4 is pressed.
5, the opening signal is transmitted to the controller 57, and the lid opening / closing motor 51 is driven. The lid opening / closing motor 51 rotates the opening / closing shaft 87 in the opening direction, and the closing lid 12 is opened.

That is, since an opening / closing switch such as a manual switch 45 for opening / closing the closing lid 12 is provided, it is not necessary to grasp a part of the closing lid by hand as in the conventional case, and to open / close the opening / closing switch. It can be opened and closed simply by touching, so that hands and clothes do not become dirty with dirt attached to the charging lid 12, and this is preferable from the viewpoint of hygiene. Further, since the on / off operation of the open / close switch requires much less labor than the conventional open / close operation performed by manually gripping and moving a part of the input lid, a garbage can is provided. The opening / closing switch can be turned on / off to open and close the input lid 12, and there is no need to temporarily place the garbage bin and then open the input lid by hand.
The labor involved in the garbage input operation can be greatly reduced.

An open / close switch is provided on the manual switch 45 provided on the upper surface or the periphery of the input lid 12 as described above.
If you use the palm and elbows, or part of the garbage can,
The input lid 12 can be reliably opened at a timing desired by the operator, and the garbage input operation can proceed smoothly. The manual switch 45 of the present embodiment includes:
Although the single push button switch used for both on and off as described above was used, on and off switches such as a multiple push button switch with separate on and off switches and a seesaw switch that switches on and off by tilting back and forth are used. The switch is not particularly limited as long as the switch is easy to operate.

A foot switch 46 protrudes from the front lower portion of the garbage disposal machine 9 and is supported by a foot pedal 46a and an upward spring by a spring or the like. A stay 46b to be energized and a switch 4 fixed on the bottom 10c below the stay 46b
6c, and the switch 46c is a switch that switches between “open and closed” each time the switch is pressed, similarly to the manual switch 45.

In such a configuration, the foot pedal 46a of the garbage disposal machine 9 in which the loading lid 12 is closed.
Is depressed with the foot, the switch 46c is turned on by the lower portion of the stay 46b, an open signal is transmitted to the controller 57, the lid open / close motor 51 is driven by the controller 57, and the open / close shaft 87 rotates in the open direction, The charging lid 12 is opened.

That is, when the open / close switch is the foot switch 46 provided at the lower part of the garbage disposal machine 9, the foot switch 46 is easily depressed with the foot while holding the garbage box with both hands. Since the input lid 12 can be opened and the input lid 12 does not need to be touched at all, hand contact with the dirt attached to the input lid 12 can be almost cut off, and there is little occurrence of sanitary problems. . Compared with the manual switch 45, since both hands can be used only for supporting the garbage bin, the supporting force of the garbage bin is weakened by holding one hand for a long time, and garbage is erroneously spilled around the garbage input port 10a. Such troubles can be reliably avoided.

The front wall 10 on the front side of the garbage disposal 9 is also provided.
b, a non-contact switch 47 is provided, and a human body detection sensor is used for the non-contact switch 47. The human body detection sensor of the present embodiment is a pyroelectric infrared sensor that utilizes the fact that the human body temperature is higher than the surrounding temperature.In the pyroelectric infrared sensor, when a high-temperature object enters the sensor range, The amount of incident infrared rays increases and a voltage is generated, so that the approach of an object can be detected. Whether or not the object is a human body is determined in advance by setting a threshold voltage of the human body, and when the voltage at which the threshold value is exceeded exceeds the threshold, it is determined that the object is a human body.

A non-contact switch 47 using such a pyroelectric infrared sensor is provided with a detection head 47a for detecting infrared rays, and is provided by the detection head 47a.
A non-contact switch 4 that detects a temperature rise due to the human body temperature
7, a non-contact switch 47 is turned on, an open signal is transmitted to the controller 57, and the lid opening / closing motor is transmitted by the controller 57 based on the open signal. 51 is driven to rotate the opening / closing shaft 87 in the opening direction, and the loading lid 12 is opened.

That is, when the open / close switch is a non-contact switch 47 using a human body detection sensor provided on the top or side surface of the machine body, it is turned on simply by approaching the garbage disposal machine 9 while holding the garbage box. The lid 12 can be opened,
Since the worker can concentrate on only the garbage input operation, the efficiency of the garbage input operation can be further improved. In addition, as the human body detection sensor, in addition to the pyroelectric infrared sensor of the present embodiment, a sensor using capacitance or a sensor using high frequency may be used.
If the approach of the human body can be detected quickly and reliably,
There is no particular limitation.

Next, such open / close switches 45 and 46
An automatic opening / closing control mechanism of the input lid 12 using the 47 will be described with reference to FIGS. 5, 6, and 7
As shown in the figure, on the operation panel 13, a detection mode setting device 48, an open hold time setting device 49, and a grace time setting device 50 are provided. It is connected to the controller 57 that controls the rotation drive of the opening / closing motor 51.

The detection mode setting unit 48 selects an operable open / close switch from among the open / close switches 45, 46, 47.
Opening and closing control by the hand switch, opening and closing control by the foot switch 46 in the foot mode, opening and closing control by the non-contact switch 47 in the sensor mode, and these are referred to as detection modes, and one or more of these modes can be selected. I have to.

The open hold time setting unit 49 sets a time (hereinafter referred to as an "open hold time") for holding the open state from when the open / close switch is turned on and the closing lid 12 is opened until it is closed. If the open holding time is too short, the garbage input operation must be performed in a hurry, causing a problem that garbage is spilled around the garbage input port 10a by mistake. If the length is too long, the odor of the garbage will escape to the outside of the tank, the insects will approach, and the loss of heat will be prevented.

The grace time setting unit 50 is a controller that, when the detection head 47a detects a human body and the non-contact switch 47 is turned on while the detection mode is the sensor mode, the controller 57 actually operates the lid opening / closing motor 51. A time lag (hereinafter referred to as “grace time”) until an open signal is issued is set separately. By providing the time lag, a person can simply pass in front of the garbage disposal machine 9 so that the loading lid can be closed. It is possible to prevent such a trouble that the opening 12 is opened.

In such a configuration, the automatic opening / closing control of the charging lid 12 is performed according to the following procedure. As shown in FIG. 8, first, the open hold time and the grace time are input by the open hold time setting device 49 and the grace time setting device 50 (S1), and then the detection mode is confirmed. If the detection mode is the hand mode (S2-Y) and the manual switch 45 is turned on (S4-Y), a contact opening / closing process is performed. Then, the detection mode is the sensor mode (S3-
Y), if the non-contact switch 47 is on (S6-Y),
A non-contact opening / closing process is performed. If the detection mode is the remaining foot mode (S3-N) and the foot switch 46 is turned on (S5-Y), a contact opening / closing process is performed.

As shown in FIG. 9, the contact opening / closing process S7
In, the controller 57 transmits an opening signal to the lid opening / closing motor 51 to open the loading lid 12 (S9), and counts an elapsed time since the loading lid 12 was opened (hereinafter referred to as “opening time”). To go. And the controller 57
When the open time exceeds the open hold time set by the open hold time setting unit 49 (S10-Y), a closing signal is transmitted to the cover opening / closing motor 51 to close the closing cover 12 (S11).

As shown in FIG. 10, in the non-contact opening / closing process S8, the controller 57 determines the elapsed time from when the approach of the human body is detected and the open signal is received from the non-contact switch 47 (hereinafter referred to as "detection time"). If the detection time exceeds the grace time set by the grace time setting device 50 (S12-Y), an opening signal is transmitted to the cover opening / closing motor 51 to open the closing cover 12 (S13). . At the same time, the controller 57 counts the open time,
If the open time exceeds the open hold time set by the open hold time setting device 49 (S14-Y), a closing signal is transmitted to the cover opening / closing motor 51 to close the closing cover 12 (S15).

That is, since the loading lid 12 is configured to be capable of automatic opening / closing control in this manner, after the garbage loading operation is completed, a part of the loading lid 12 is grasped and reclosed by hand, or various opening / closing operations are performed. The turning off of the switches 45, 46, and 47 can be omitted without fail, and even after the garbage input operation is completed, the input lid 12 does not need to be touched at all. Hand contact can be completely eliminated and no hygiene problems arise. In addition, since the loading lid 12 automatically closes, it is possible to completely prevent forgetting to close after the garbage loading operation, and to reliably prevent the odor of the garbage from escaping outside the tank, approaching insects, and losing heat. You can do it.

In addition to providing a plurality of open / close switches,
Since the detection mode setting device 48 which can preset the opening / closing switches 45, 46, 47 to be operated is provided, the non-contact switch 47 which can concentrate on carrying and putting in the garbage bin with both hands for a weak elderly person or a child is used. Can be easily switched to a detection mode suitable for the worker,
It is possible to strongly support the worker's garbage input work.

Next, the deodorization when opening the charging lid 12 is performed.
An air curtain effective for heat insulation will be described with reference to FIGS. 7, 11, and 12. FIG. As shown in FIGS. 11 and 12, the fermenter 1 in the vicinity of the exhaust unit 20 is formed with a fan case 1 c that is concaved inward in a substantially fan shape when viewed from the side, and the fan case 1 c and the rear wall 10 e are formed. Screen fan 5 between
2 are interposed.

The screen fan 52 is composed of a plurality of fins 52a that are laterally mounted on the fan case 1c.
52a, and support plates 52b, 52b for supporting the left and right ends of the fins 52a, 52a, and the substantially central portions of the left and right support plates 52b, 52b. Fin shaft 5 rotatably fitted to the boss portion
2c and a fin motor 53 having an output shaft connected to the right end of the fin shaft 52c. The fin 52a
Reference numeral 52a denotes a band-like plate formed in a substantially crescent shape in a side sectional view, and is disposed on the circumference in the support plates 52b.

Above the screen fan 52, an air outlet 54 extending forward from the upper part of the fermenter 1 and the rear wall 10e is formed, and on the same plane as the air outlet 54. An air inlet 55 extends rearward from the fermenter 1 and the upper portion of the front wall 10b. Also,
In the vicinity of the suction port below the screen fan 52, a cartridge 93 filled with a deodorant is replaceably mounted.

Here, as shown in FIG. 7, the fin motor 53 is connected to a controller 57 for automatically controlling the opening and closing of the loading lid 12, and an opening signal is transmitted from the controller 57 to the lid opening and closing motor 51. At this time, a drive signal is also transmitted to the fin motor 53 at the same time.

In such a configuration, when the loading lid 12 is opened, the fin motor 53 is automatically driven to drive the fin shaft 5.
2c rotates, and the fin 5 rotates about the fin shaft 52c.
2a, 52a, ... rotate. Then, the air in the air passage 88 below the fermenter 1 is sucked up, and is blown out in a band shape over the entire upper surface of the fermenter 1 from the air outlet 54 above the screen fan 52 to close the upper part of the fermenter 1. An air curtain is formed, and the effect of the air curtain suppresses the odor 92 rising from the processing object 80 and the escape of hot air.

Further, when the blown-out air takes in the odor 92 and the like and is sucked through the air suction port 55, the air passes through the air passage 88 and the deodorant in the cartridge 93 is mixed. It is sucked and blown out from the air blowout port 54 to form an air curtain. By such air circulation, the fin motor 53
During driving, the fermenter 1 is always closed by the air curtain.

That is, by providing an air curtain near the inlet 1e and mixing a deodorant into the air to be blown out, the odor 92 and the escape of hot air rising from the processed material 80 even during the garbage input operation are effectively suppressed. Therefore, a favorable working environment for the worker can be ensured, and a decrease in the fermentation decomposition efficiency can be prevented.

Incidentally, instead of the cartridge 93 filled with the deodorant, an ozone generator 89 or an activated carbon cartridge 15 may be provided. In this case, the ozone generator 89 is attached to the upper and lower portions of an air discharge passage 91 formed between the fermenter 1 and the front wall 10b below the air suction port 55, and below it, activated carbon Cartridge 9
0 is interchangeably mounted. The ozone generator 89 is also connected to the controller 57 that performs automatic opening / closing control of the loading lid 12, and when an open signal is transmitted from the controller 57 to the lid opening / closing motor 51, similarly to the fin motor 53, The drive signal is also transmitted to the ozone generator 89.

In such a configuration, when the loading lid 12 is opened, the ozone generator 89 operates together with the fin motor 53 to decompose the odor in the air sucked from the air suction port 55 with ozone. The activated carbon removes the ozone odor, and the purified air is blown out from the air blowout port 54, so that a better working environment can be secured.
