Description

food waste disposer

technical field

The invention relates to a food waste disposer.

Background technique

Existing general garbage disposer is to directly discharge the treated garbage into the sewer or throw it in the trash can, which will cause hygienic problems such as peculiar smell, breeding of pests and mice. In order to overcome this problem, Korean Utility Model Announcement No. 1996-0010343 requires the installation of waste disposal devices to dispose of food waste discharged from households or canteens in a more hygienic manner.

The structure of the existing food waste disposer is as follows: an inner barrel with a drain outlet and an air purification device at the lower part is installed in the barrel, a heating device is installed inside the inner barrel, an insulated container is connected with the food waste collection box, and the food waste collection box There is a stirring wheel, and the stirring wheel is connected with the motor in transmission, and the heat exhausting device is installed on the cover.

The operation sequence is: first open the cover, put a certain amount of food waste into the food waste collection bin connected to the heat-insulated container, and close the cover; start the control device, and at this time the hot air exhaust device on the cover discharges hot air downwards, At the same time, driven by the motor, the stirring wheel rotates and breaks the food waste into small pieces. At this time, the moisture contained in the waste will evaporate and be discharged into the In the lower drain outlet; after the odor in the food waste is treated by the air purification equipment, it is discharged. After performing the above process for a period of time, the food waste in the food waste collection bin will be completely dehydrated and deodorized, and form a small powder, so it is easy to throw away or can be used as fertilizer for flowers and trees. Disposing of food waste under the condition of ensuring sanitation can prevent environmental pollution caused by food waste.

However, the heat exhaust air equipment in the existing food waste disposer is usually installed on the cover on the upper part of the heat-insulating container, so the structure of the cover will become very complicated, and the design of the cover will also be greatly restricted. At the same time, the temperature of the cover equipped with the heat exhausting air device will increase during operation, resulting in reduced use safety. And the existing garbage disposer must first open the cover during operation, then put the food waste into the food waste collection connected to the heat-insulating container, and start it with the control device after covering the cover, so it is very inconvenient to use.

Contents of the invention

The object of the present invention is to provide a more convenient food waste disposer.

The technical solution of the present invention is: a food waste disposer, which includes a main body, an outer barrel installed in the main body, an inner barrel with crushing blades installed in the outer barrel, and an inner barrel installed in the main body The motor that drives the crushing blade, the heater that heats the food waste in the inner barrel and adheres to the outer barrel, the exhaust pipe that communicates with the inner barrel, and connects with the exhaust pipe The exhaust fan used to discharge the gas in the inner tub, the control part of the motor and heater and the exhaust fan, measures the temperature between the outer tub and the inner tub and sends it to the Temperature switch of the control part.

A filter is installed on the top of the exhaust pipe.

The main body is provided with an exhaust pipe bracket for supporting the exhaust pipe.

Compared with the prior art, the present invention has the following advantages: It can be seen from the above structure that the heater is installed at the bottom of the outer barrel, so the conduction and radiation heat generated by the heater will accelerate the temperature rise of the food waste in the inner barrel , Compared with the existing structure where the heater is installed on the upper part of the cover, the structure of the cover part of the main body is simpler, and the degree of freedom in designing the cover becomes larger, which can avoid excessive temperature generated on the cover and improve the stability of the product.

In addition, the heater adopts an annular tube type, the heating effect becomes better, and the main body space for installing the heater is also greatly reduced, thereby reducing the overall appearance size.

In the present invention, a temperature switch capable of measuring the temperature between the outer barrel and the inner barrel is adopted, and the drying and crushing operations of food waste are automatically controlled according to the temperature change between the inner barrel and the outer barrel, thereby improving the commerciality of the product.

Since the filter is installed at the upper end of the exhaust pipe, replacement is easy.

A bracket capable of supporting the exhaust pipe is installed in the main body, so that the exhaust pipe is firmly installed on the main body at the lower part of the filter.

Because the exhaust fan is installed at the end of the exhaust pipe, the suction of the exhaust fan is used to discharge the odor and water vapor generated during the drying and crushing process of food waste through the above exhaust pipe. This structure is better than the existing one. The structure installed on the upper part of the inner barrel reduces the splash of garbage caused by the direct injection of hot air during the exhaust process, so it can be kept clean.

The structure of the cover part where the main body of the exhaust fan is installed is also simplified, which improves the degree of freedom in designing the cover, reduces overheating of the cover, and improves product stability.

Because the outer barrel and the inner barrel are connected by the first connecting piece and the second connecting piece, the outer barrel and the inner barrel cannot rotate left and right relative to each other, but can only be separated up and down, so it is easy to separate or assemble the inner barrel. After crushing and drying the food waste, you only need to extract the inner bucket, and you can easily throw away the garbage, and the cleaning of the inner bucket after throwing away the garbage is also very simple.

In the present invention, the heater and the crushing blade are automatically stopped by opening or closing the cover, and the user can operate without using other operating means, so it is very convenient to use.
