Description
Technical Field
[0001] This utility model relates to the field of garbage bin technology, specifically a refrigerated kitchen waste bin. Background Technology
[0002] Kitchen waste has always constituted a large proportion of all household waste. The vast majority of kitchen waste is organic matter, which is prone to rotting and deterioration when piled up in garbage cans, emitting unpleasant odors. This phenomenon is especially pronounced in the hot summer when the ambient temperature is high, making it easy for flies and insects to breed, becoming a source of germs and posing a threat to people's health. Currently, refrigerated garbage cans are used to store kitchen waste in order to delay its decomposition.
[0003] Existing refrigerated trash cans continuously release cold air during operation to slow down the decomposition of food waste. However, as the cold air circulates, it can easily carry away the odors and bacteria from the food waste itself, thus polluting the surrounding air. Furthermore, after prolonged use, refrigerated trash cans require internal rinsing and sterilization, but manual cleaning is troublesome and inefficient. Therefore, we have proposed a refrigerated food waste bin. Utility Model Content
[0004] The purpose of this utility model is to provide a refrigerated food waste bin to solve the problems mentioned in the background art. Existing refrigerated garbage bins continuously release cold air during operation to slow down the decomposition time of food waste. However, the cold air tends to carry away the odor and bacteria of the food waste itself during its flow, thereby polluting the surrounding air. Furthermore, after prolonged use, refrigerated garbage bins require internal rinsing and sterilization, but manual cleaning is troublesome and inefficient.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigerated kitchen waste bin, comprising an outer bin, a purification box, and a water tank. The purification box is fixedly connected to the upper left side wall of the outer bin, and the water tank is fixedly connected to the middle of the right side wall of the outer bin. An activated carbon filter plate is fixedly connected between the inner side walls of the purification box. A sterilization box is fixedly connected to the bottom of the purification box, and the sterilization box is connected to the sterilization box via a pipe. An ultraviolet lamp is fixedly connected to the inner side wall of the sterilization box. A deodorization box is fixedly connected to the bottom of the sterilization box, and the deodorization box is connected to the sterilization box via a pipe. A bamboo charcoal deodorizing agent filter plate is fixedly connected between the inner side walls of the deodorization box, and an air outlet is provided on the left side wall of the deodorization box.
[0006] As a further description of the above technical solution:
[0007] The inner tub is placed inside the outer tub. An air conditioner is fixedly connected to the lower left side wall of the outer tub. A connecting pipe is fixedly connected to the top of the air conditioner. The end of the connecting pipe passes through the outer tub and extends into the inner tub. A one-way valve is fixedly connected to the middle of the outer side wall of the connecting pipe via a flange.
[0008] As a further description of the above technical solution:
[0009] The top of the outer barrel is rotatably connected to a barrel lid, a handle is fixedly connected to the top left side of the barrel lid, a groove is opened at the bottom of the barrel lid, a spray pipe is fixedly connected to the top of the inner cavity of the groove, and a high-pressure nozzle is fixedly connected to the bottom of the spray pipe.
[0010] As a further description of the above technical solution:
[0011] A drain pipe is fixedly connected to the lower right side wall of the outer barrel, and a valve is fixedly connected to the middle of the outer side wall of the drain pipe via a flange.
[0012] As a further description of the above technical solution:
[0013] A water inlet pipe is fixedly connected to the upper right side wall of the water tank, a feed port is fixedly connected to the top right side of the water tank, and a water pump is fixedly connected to the top left side of the water tank. The water pump is connected to the water tank and the spray pipe through a telescopic hose.
[0014] As a further description of the above technical solution:
[0015] A motor is fixedly connected to the bottom center of the water tank. The end of the motor's power output shaft passes through the water tank and extends into the inner cavity of the water tank. A stirring rod is fixedly connected to the end of the motor's power output shaft.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This refrigerated kitchen waste bin uses flowing cold air to enter the purification chamber through pipes. The activated carbon filter plate initially purifies the cold air, reducing odors. Then, the cold air enters the sterilization chamber, where ultraviolet lamps emit ultraviolet light to irradiate the cold air, killing bacteria carried in it. Finally, the cold air enters the deodorization chamber, where bamboo charcoal deodorizing filter plates further purify and deodorize the cold air, completely eliminating odors. This prevents the device from carrying kitchen waste odors to the outside environment, avoiding air pollution.
[0018] 2. This refrigerated kitchen waste bin allows disinfectant to be added through the filling port, while a water supply pipe delivers clean water to the water tank. Both disinfectant and water enter the tank, and a motor drives a stirring rod to mix the disinfectant and water evenly, forming a disinfectant solution. A water pump then pumps the solution to a spray pipe, where high-pressure nozzles spray the solution onto the inside and outside of the outer bin, thus disinfecting and rinsing both surfaces. Finally, by opening a valve, the wastewater generated during cleaning is discharged through a drain pipe. This automatic disinfection and rinsing system improves cleaning efficiency.
