Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a household waste disposal device for incinerating and reducing the amount of garbage such as kitchen waste.

2. Description of the Related Art Conventionally, this type of waste treatment apparatus has had a configuration as shown in FIG. In the figure, a frame body 101 having a lid 104 that can be opened and closed, into which garbage 106 is thrown, has a heat-resistant furnace material 102 provided on its inner wall surface.

A heater 103 protruding into the frame 101 is provided at the inner bottom of the frame 101. Further, inside the frame 101, a garbage processing device 105 is arranged, which has a protrusion 105a surrounding the heater 103 at the bottom. Frame body 101
An air supply port 107 is provided at the bottom of the frame body 101, and an air supply blower 108 is connected thereto to supply air necessary for combustion into the frame body 101. Further, an exhaust port 109 is provided on the side surface of the frame body 101 for exhausting exhaust gas generated by combustion of garbage.
is connected to an exhaust gas purifier 110 via a flue. The purifier 110 is configured by arranging a rod-shaped exhaust gas heating heater 111 and an oxidation catalyst 112 in this order from an exhaust port 1091111. These were covered with an outer shell 113, and the exhaust gas from the purifier 110 was discharged from an exhaust pipe 114.

With the above configuration, when the waste 106 is put into the processing container 105 and the heater 103 is energized, the energy of the heater 103 is efficiently given to the waste 106 to heat the inside of the frame 101, and the waste 106 is dehydrated and dried. Once it becomes a fist, it will eventually ignite and burn, turning into ash. The exhaust gas generated at this time is led into the purifier 11o, heated by the exhaust gas heating heater 111, purified by the oxidation catalyst 112, and discharged from the exhaust pipe 114.

Problems to be Solved by the Invention When such a conventional configuration is installed in a home kitchen, it is necessary to drill a hole in the wall of the kitchen in order to vent the exhaust gas from the waste disposal device to the outside. Installation was time-consuming and there were issues with workability. Therefore, it is possible to connect the exhaust stack 114 to the ventilation system in the kitchen using a duct, but the amount of air that pulls the exhaust gas will not be constant depending on the air volume of the ventilation system, and the ventilation air volume will be larger than the amount of exhaust gas exhausted. As a result, the amount of air supplied to the waste disposal equipment is reduced and increases, making incineration unstable.The amount of exhaust gas also increases and the temperature inside the purifier decreases, resulting in poor purification efficiency and odor and smoke. The problem was that it was more likely to occur.

The present invention solves the above-mentioned problems, and provides an easy-to-install garbage disposal device that eliminates the need to make holes in the walls of the kitchen during installation, and can properly dispose of garbage regardless of the air volume of the ventilation system. The purpose is to

Means for Solving the Problems In order to achieve the above objects, the present invention provides a combustion furnace for reducing waste by incineration, an exhaust port for exhausting exhaust gas generated in the combustion furnace, and a combustion furnace provided in communication with the exhaust port. a purifier that purifies the exhaust gas, a duct that connects the exhaust gas purified by the purifier to the kitchen ventilation system, an exhaust air volume variable device installed in the exhaust route leading to the duct, and an air volume selector switch of the ventilation system. Ni17Il/f confirms the operation of the ventilation system based on the signal from the operation state verification means, and when the ventilation system is stopped based on the signal from the operation state verification means, the ventilation system is driven and the garbage disposal is started. The ventilator operation means stops the ventilation device when the ventilation device is completed, and the exhaust air volume variable device drive means changes the exhaust air volume variable device according to the driving state of the ventilation device.

Effect With this configuration, the exhaust gas from the combustion furnace is guided to the ventilation system in the kitchen through the duct, and the signal from the air volume selector switch of the ventilation system is judged by the operating status confirmation means of the ventilation system, and the ventilation system is stopped. When the ventilation system is running, the ventilation system is operated with a predetermined air volume using the ventilation system operating means, and the
When the ventilation system is in operation, the exhaust air volume variable drive means drives the exhaust landscape variable device to set the exhaust air volume to a predetermined value, so that garbage can be disposed of normally regardless of the air volume of the ventilation system.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. In Figure 1, 1 is a frame made of a highly heat-resistant material such as metal or ceramic in the shape of a box. Material 2 is lined. A heater 3 is provided at the inner bottom of the frame 1, penetrating the furnace material 2 from the outside and protruding into the frame 1. Further, a lid 4 that can be opened and closed is provided on the top of the frame 1 so that garbage 8 can be thrown in. Further, above the heater 3, there is disposed a waste processing container 6 having a concave portion at the bottom so as to enclose the heater 3, so that the waste 6 is stored in the processing container 6.

The frame 1, furnace material 2, heater 3, and processing container 6 constitute a combustion furnace. In addition, an air supply lower is opened at the bottom of the frame 1, and the air necessary for combustion of the garbage 6 is introduced by a blower 8, and the exhaust gas generated by the combustion is discharged through the exhaust gas opened at the side wall of the frame 1. The gas is introduced into a purifier 10 communicating with the port 9, heated by an exhaust gas heating heater 11, purified through an oxidation catalyst 12, and connected to an exhaust gas intake port 17d of a ventilation device 17 through a duct 15.

These are covered by an outer shell 13.

Further, an exhaust air volume variable device 16 is provided in the exhaust path 15a leading to the duct 16, so that the cross-sectional area of the exhaust path leading to the duct 16 can be changed by changing the angle of a damper provided in the exhaust path 15a. It has become. Further, the ventilation device 17 includes an exhaust gas intake port 17a and a general intake port 17.
b, and a ventilation opening 18, and is ventilated by a ventilation blower 19. The control means 22 includes an operation state confirmation means 23 for inputting a signal from the air volume selector switch 21 of the ventilation apparatus 17, a ventilation apparatus driving means 24 for driving the ventilation apparatus 17 based on this signal, and a ventilation air volume variable control means 23 for checking the operating state of the ventilation apparatus 17. and a ventilation air volume variable device driving means 25 that drives the ventilation airflow rate variable device 16. Note that 2o is a start switch that starts the garbage processing operation.

In the above configuration, the waste 6 is thrown into the processing container 6 by opening the lid 4. Then, when the start switch 20 is turned on, the heater 3 is energized and generates heat, so the waste 6 is heated and dehydrated, and then ignited and reduced in volume by incineration. At this time, the air necessary for combustion enters the frame 1 through the air supply lower opening in the frame 1 through the blower 8, and the exhaust gas generated by the combustion of the garbage 6 enters the frame 1 through the exhaust port opened in the frame 1. The exhaust gas is guided into the purification i10 connected to the exhaust gas heater 11, heated by the exhaust gas heating heater 11, purified by the oxidation catalyst 12, and then introduced into the duct 15.

Next, the principle of setting the exhaust air volume of exhaust gas will be explained with reference to FIG. 2. The processing time t of the garbage processing device. During this period, the operating state checking means 23 detects the vJ operation state of the air volume selector switch 21 of the ventilation device 17, and accordingly, the exhaust air volume variable device 16 changes the air volume selector switch 21 of the ventilation device 17 during the time period t2, for example. is the dedicated notch for waste disposal, but at that time the exhaust air volume variable device 16 is opened to the dedicated air volume state. During the time period t3, the air volume selector switch 21 is set to a low level by the user, and at that time, the air volume drawn by the ventilation device 17 increases, so that the exhaust air volume of the waste disposal device increases. Therefore, in order to keep the exhaust air volume constant, the exhaust air flow rate variable device 16 is used to narrow the exhaust route. Similarly, at times t4 and t6, the exhaust air volume variable device 16 is changed to change the cross-sectional area of the exhaust path 16a in order to keep the exhaust air volume constant according to the change in the air volume of the ventilation device 17. Also, during the time periods tl and t6, when the garbage 6 is not being processed, the ventilation system 17 is operating with the air volume selector switch 21 in the notch state, and in the case of t6, the garbage processing is completed. This shows that the ventilation 2 device 17 continues to operate even when the air conditioner is on.

FIG. 3 shows an example of a specific circuit of the main part. Ventilation device 1
7 and the exhaust air volume variable device 16 are connected to an AC power source via a ventilation system operating means 24 and an exhaust air volume variable device driving means 26 controlled by the control means 22. This control means 22 uses a signal from the start switch 20 to turn on the ventilation system operating means 24 so that the ventilation system 17 is driven with the air volume of the garbage processing notch if the air volume selector switch 21 is in the off state. Then, the exhaust air volume variable drive means 26 is turned on so that the exhaust air volume variable device 16 is driven in the dedicated notch state. When the ventilation device 17 is used at a different air volume by manually switching the air volume changeover switch 21 during the primary processing, the exhaust air volume variable device 16 is also set to a damper angle corresponding to the air volume. Once the waste 6 has been disposed of, the ventilation system 17 continues to operate with the air volume selector switch 21 manually turned on.

Next, the operation of the exhaust gas ventilation process of the garbage disposal device will be explained using the flowchart shown in FIG. When the garbage disposal device is started, the operating state checking means 23 determines whether the air volume selector switch 21 of the ventilation device 17 is in an off, dedicated, weak, or strong state. (Step 41). If the ventilator 17 is in the off state, the ventilation device 17 is driven in the dedicated notch by the ventilation device driving means 24 in step 42, and in step 43, the exhaust air volume variable device 16 is driven in the dedicated notch state by the exhaust landscape variable drive means 26. be made into

If it is determined in step 44 that the garbage disposal device has stopped, the ventilation device 1 is stopped in step 46, and the ventilation process is ended. In addition, if the air volume selector switch 21 is found to be switched to the weak notch during processing, or if it is determined in step 41 that the air volume selector switch 21 has been operating in the weak notch before the processing, the operating state confirmation means 23 When it is determined that the selector switch 21 is in the weak notch position (step 46), the exhaust air volume variable drive means 26 operates the exhaust air volume variable device 16 to the weak notch position (step 46).
7). If it is determined in step 48 that the garbage disposal device has stopped, the ventilation device 17 continues to be operated at a weak notch and ends. Similarly, during processing, the air volume selector switch 21
If it is determined in step 41 that the air volume switch 21 has been switched to a strong notch or has been operating in a strong notch before the processing, it is determined in step 46 that the air volume changeover switch 21 is in a strong notch,
After the exhaust air volume variable device is set to high level (step 49) and the garbage disposal equipment is stopped, the ventilation system 17 continues to be operated at the high level, and the process ends. Note that the ventilation device 17 has a strong and weak air volume selector switch, and the ventilation device 17 is configured to not be able to switch to a dedicated air volume.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, when a garbage disposal device is installed in a kitchen, the exhaust pipe is connected to the ventilation system of the kitchen through a duct, and the exhaust of the kitchen garbage disposal device is Since the structure is equipped with a means to control the air volume, it is possible to stably dispose of garbage without being affected by the air volume of the ventilation system. Also, there is no need to make a separate hole for the exhaust pipe in the kitchen wall, making installation easier. Furthermore, it is possible to obtain a sanitary garbage disposal device that does not emit exhaust gas into the room.
