Description

Technical Field

[0001] The utility model relates to the technical field of household food waste disposers, in particular to a household food waste disposer with a circulating deodorizing air duct. Background Art

[0002] There are many types of household food waste, covering all kinds of waste generated during daily eating and cooking. For example, it includes vegetables, fruits, leftovers, meat and processed foods, etc. These food wastes are inevitable in daily household life, but their negative impact on the environment can be reduced through reasonable classification, storage and treatment. For example, some degradable waste can be converted into fertilizer through composting, while some recyclable waste can be reused through the recycling system.

[0003] Nowadays, household food waste disposer, as an environmentally friendly and practical kitchen equipment, can effectively reduce household waste generation and promote resource recycling; it has attracted more and more attention. The household food waste disposer is a modern kitchen equipment, which is designed to efficiently process household food waste to achieve waste reduction and resource utilization. It uses efficient grinding technology to convert food waste into tiny particles for subsequent processing, thereby reducing garbage accumulation and reducing environmental pollution.

[0004] Based on this, a Chinese utility model patent CN212069021U discloses a kitchen waste disposer, which includes a shell, a mounting cavity is formed in the shell, and the shell is also provided with an exhaust port connected to the mounting cavity; a processing barrel, the processing barrel is arranged in the mounting cavity, a receiving cavity for receiving kitchen waste is formed in the processing barrel, the processing barrel is provided with an air vent connected to the receiving cavity, the air vent and the exhaust port are connected to form an air flow channel; and a deodorizing device, the deodorizing device is arranged in the mounting cavity and is located between the air vent and the exhaust port, and the deodorizing device is used to purify the gas discharged from the receiving cavity. During the drying process, this type of kitchen waste disposer can purify and deodorize the gas generated in the process, so as to avoid the waste gas generated in the kitchen waste treatment process from polluting the environment and improve the environmental performance of the kitchen waste disposer.

[0005] However, the above-disclosed kitchen waste disposer still has the technical problem of poor waste gas treatment efficiency. Specifically, in the prior art, most traditional household food waste disposers use multi-bacteria sealed fermentation technology in the process of treating garbage; although this technology can achieve the purpose of decomposing organic waste gas and odor, it still produces a small amount of waste gas. Usually, these remaining waste gases mainly include ammonia, hydrogen sulfide, methane or acetic acid. Although the above patent discloses a purification and deodorization structure, it is provided with a vacuum component, and the air inlet of the vacuum component is connected to the vent, and at the same time, the deodorization device is arranged between the air outlet and the exhaust port. In this way, part of the odor generated during the kitchen waste treatment process can be removed, and the gas will not be blocked from being discharged from the vent. However, this deodorization device mainly reduces the content of waste gas through a single-stage adsorption and filtration structure, and cannot efficiently remove waste gas; moreover, the single-stage adsorption structure will gradually reduce the adsorption effect as the use time increases, and needs to be replaced regularly, which is inconvenient to use.

[0030] Please also read Figures 1 to 6The household food waste disposer with a circulating deodorizing air duct of the utility model comprises: a main body 1, a barrel structure 2, a cover structure 3, a first air induction mechanism 4, a water removal device 5, a water storage tank body 6, a relay connection pipeline structure 7, a second air induction mechanism 8, a thermal treatment waste removal device 9 and a circulation pipeline structure 10; the barrel structure 2 is movably arranged in the main body 1, the cover structure 3 is movably covered and arranged on the barrel structure 2, and the cover structure 3 is connected to the main body 1; the first air induction mechanism 4 is connected to the interior of the barrel structure 2 through the main body 1, the water removal device 5 is respectively connected to the first air induction mechanism 4 and the water storage tank body 6, and the relay connection pipeline structure 7 is respectively connected to the water storage tank body 6 and the second air induction mechanism 8; the thermal treatment waste removal device 9 is connected to the end of the second air induction mechanism 8, the circulation pipeline structure 10 is connected to the thermal treatment waste removal device 9, and the circulation pipeline structure 10 is connected to the interior of the barrel structure 2 through the main body 1.

[0031] Specifically, when the household food waste disposer with a circulating deodorizing air duct of the utility model uses the main body 1 to control the processing of household food waste placed in the barrel structure 2, the barrel structure 2 will produce odorous waste gas due to the stages of processing waste such as crushing, grinding or fermentation; the waste gas will be blocked by the cover structure 3 and will not be emitted to the external environment. Thereafter, the first air induction mechanism 4 starts to work to guide the waste gas from the barrel structure 2 through the main body 1 to be introduced into the dewatering device 5, and the dewatering device 5 controls the precipitation of water vapor in the waste gas, so that the water vapor in the waste gas condenses into water droplets and gathers in the water storage tank body 6. The waste gas with precipitated water vapor continues to be guided by the first air induction mechanism 8, through the relay connection pipeline structure 7, and passes through the thermal treatment waste removal device 9; after the thermal treatment waste removal device 9 is powered on and started, it can generate high temperature to heat and burn the waste gas; finally, the gas containing odor components in the waste gas is completely removed. Specifically, the kitchen waste contains a large amount of organic matter, such as leftovers, vegetable roots and leaves, skins, hair, fats, etc. of poultry, animals and fish, as well as a certain amount of water. These organic matters, under suitable temperature and humidity conditions, especially in the case of insufficient oxygen, will be affected by anaerobic bacteria, resulting in incomplete oxidation and decomposition of the organic matter, producing gases with pungent odors such as hydrogen sulfide and ammonia. Secondly, there are also a large number of bacteria and fungi in the kitchen waste. These microorganisms will produce odorous metabolites, such as hydrogen sulfide and ammonia, in their life activities, which further aggravates the generation of odors. In addition, the food residues that are not completely digested in the kitchen waste, such as bones, peels, vegetables, etc., are also prone to anaerobic fermentation during the stacking process, producing odorous organic acids and alcohols. These gases are highly volatile and easy to diffuse in the atmosphere, and some gases are toxic and have a strong pungent odor. However, the aforementioned hydrogen sulfide, ammonia, organic acids or alcohols can be heated and decomposed under the action of high temperature, and the final products are all colorless and odorless safe gases. After that, the gas after waste removal flows through the circulation pipeline structure 10 and the main body 1, and then flows back into the barrel structure 2. The aforementioned waste gas outflow, water removal, waste removal and backflow treatment process will be repeated many times until there is no waste gas remaining in the barrel structure 2; thereafter, when the user opens the cover structure 3 to clean the residue in the barrel structure 2, there will be no odor.

Specifically, the inner cavity of the barrel structure 2 is connected to the first air-inducing mechanism 4 and the circulation pipeline structure 10 respectively through the air-permeable grille structure 107b, thereby forming a circulation deodorizing air duct structure.

[0036] Further, the first air induction mechanism 4 has a first air permeable grid lower structure 401, a first air induction channel 402, a first centrifugal fan structure 403 and a dewatering connection pipeline structure 404; the first air permeable grid lower structure 401 is connected to the air permeable grid upper structure 107c, the first air induction channel 402 is respectively connected to the first air permeable grid lower structure 401 and the first centrifugal fan structure 403; the first centrifugal fan structure 403 is connected to the dewatering connection pipeline structure 404, and the dewatering connection pipeline structure 404 is respectively connected to the first centrifugal fan structure 403 and the water storage tank body 6. Specifically, the first centrifugal fan structure 403 can guide the gas inside the barrel structure 2 to the dewatering device 5.

[0037] Furthermore, the dewatering device 5 comprises a first heat sink group 501, a semiconductor refrigeration unit 502, a second heat sink group 503 and a heat dissipation fan structure 504; the first heat sink group 501 is arranged in the dewatering connection pipeline structure 404, the semiconductor refrigeration unit 502 is arranged on the side of the dewatering connection pipeline structure 404, the second heat sink group 503 is arranged outside the dewatering connection pipeline structure 404, the semiconductor refrigeration unit 502 is respectively connected to the first heat sink group 501 and the second heat sink group 503; the heat dissipation fan structure 504 is connected to the adjacent side of the second heat sink group 503. Specifically, when the waste gas containing moisture enters the dewatering connection pipeline structure 404, the first heat sink group 501 arranged in the dewatering connection pipeline structure 404 can exchange the heat in the waste gas, so that the waste gas is cooled, thereby condensing and precipitating the moisture in the waste gas. After the heat is exchanged to the first heat sink group 501, the semiconductor refrigeration unit 502 further absorbs the heat of the first heat sink group 501 and transfers the heat to the second heat sink group 503 disposed outside the water removal connection pipe structure 404; and the second heat sink group 503 can diffuse the heat into the surrounding air through the air cooling effect of the heat dissipation fan structure 504.

Specifically, the incineration channel structure 901 is a stack-shaped structure, which can buffer the dried waste gas therein, and according to its shape, the waste gas is introduced from one end of the dense through-hole structure 902 and discharged from the other end thereof. The dense through-hole structure 902 is a columnar structure as a whole, and its interior is a dense honeycomb through-hole structure, and the through-holes are evenly distributed throughout it; at the same time, the upper and lower parts of the dense through-hole structure 902 are connected to the electric heat control unit 903, and the electric heat control unit 903 can be connected to the external power supply through the control circuit board module 104, so that it can start to power on and transfer heat to the through-hole honeycomb structure 401. When the through-hole honeycomb structure 401 is powered on, it can reach a preset temperature, for example, the temperature is preset to about 260°C. Under this temperature condition, the odorous organic acids, alcohols or hydrogen sulfide contained in various exhaust gases can be effectively confined within the honeycomb through-holes and heated for thermal decomposition, so that they can eventually form odorless gas; so that the gas sent to the circulation pipeline structure 10 can be completely thermally decomposed to achieve the function of purification and deodorization.

[0040] Furthermore, the circulation pipeline structure 10 has a deodorization connection pipeline structure 1001 and a second air-permeable grid lower structure 1002; the deodorization connection pipeline structure 1001 is respectively connected to the incineration channel structure 901 and the second air-permeable grid lower structure 1002, and the second air-permeable grid lower structure 1002 is connected to another air-permeable grid upper structure 107c relative to the first air-permeable grid lower structure 401.
