Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and more specifically, to a kitchen waste treatment machine. Background Technology

[0002] Most food waste consists of liquid food scraps and household waste with high water content. If it accumulates for a long time, it will produce a very strong odor and harmful bacteria. Usually, it needs to be dehydrated by a food waste disposer. Common food waste disposers use a built-in hot air supply device to dry the food waste after it is loaded.

[0003] However, some food waste disposers have deficiencies in their airflow design, which can affect drying efficiency. For example, some hot air may be exhausted to the outside through the air outlet before entering the food waste storage area, resulting in a reduction in the amount of hot air used to dry the food waste. Also, after drying the food waste, all the hot air may be exhausted to the outside, requiring the fresh air to be reheated, which increases the air heating time. Utility Model Content

[0021] The kitchen waste disposal machine of this utility model includes a shell structure 100 and a hot air supply device 200. The shell structure 100 has a first air inlet 103 and a first air outlet 104. The shell structure 100 is provided with a first cavity 105, a second cavity 106 and a third cavity 107. The first cavity 105 is connected to the first air inlet 103. The second cavity 106 is connected to the first air outlet 104. The third cavity 107 is connected to the first cavity 105 and the second cavity 106 respectively, and is used to contain kitchen waste. The hot air supply device 200 is disposed in the first cavity 105. The inlet of the hot air supply device 200 is connected to the first cavity 105 and the first air inlet 103. The outlet of the hot air supply device 200 is connected to the third cavity 107. The hot air supply device 200 is used to deliver hot air into the third cavity 107.

[0022] Specifically, such as Figure 1 , 2 As shown, the top of the shell structure 100 is provided with a first air inlet 103 and a first air outlet 104. The upper part of the shell structure 100 has a first cavity 105 and a second cavity 106, and the lower part of the shell structure 100 has a third cavity 107. The first cavity 105 and the second cavity 106 are respectively connected to the first air inlet 103 and the first air outlet 104. The top of the third cavity 107 is connected to the lower part of the first cavity 105 and the lower part of the second cavity 106, and is used to contain kitchen waste. The hot air supply device 200 is disposed in the first cavity 105. Its inlet is connected to the first cavity 105 and the first air inlet 103, and its outlet is connected to the third cavity 107. When the hot air supply device 200 is working, it is used to deliver hot air into the third cavity 107.

[0023] In this embodiment, when the hot air supply device 200 is working, air enters the first chamber 105 through the first air inlet 103, is heated by the hot air supply device 200, and then enters the third chamber 107 to dry the kitchen waste. During this process, the hot air has no way to escape before reaching the third chamber 107, reducing the loss of hot air before it enters the waste storage area. Subsequently, a portion of the hot air in the third chamber 107 is discharged from the first air outlet 104 through the second chamber 106; another portion of the hot air in the third chamber 107 flows back to the first chamber 105, mixes with a small amount of fresh air, and is reheated, achieving "waste heat circulation" instead of complete exhaust, thereby avoiding prolonged temperature rise caused by "reheating fresh air". In summary, the kitchen waste processor of this utility model effectively improves the drying efficiency.

[0024] Optionally, the housing structure 100 includes an upper housing 101 and a lower housing 102; the upper housing 101 is detachably mounted on the lower housing 102; the upper housing 101 has a first air inlet 103 and a first air outlet 104, and has a first cavity 105 and a second cavity 106 inside; the lower housing 102 has a third cavity 107 inside.

[0025] Specifically, the housing structure 100 includes two detachable parts, namely an upper housing 101 and a lower housing 102; as Figure 1 As shown, the lower housing 102 has a third cavity 107 inside, and the lower housing 102 has a first mounting port that communicates with the third cavity 107. The lower end of the upper housing 101 is supported at the first mounting port and the first mounting port is sealed. The top of the upper housing 101 has a first air inlet 103 and a first air outlet 104, and has a first cavity 105 and a second cavity 106 inside. The lower housing 102 has a third cavity 107 inside.

[0026] In this optional embodiment, since the upper housing 101 is integrally integrated with the first air inlet 103, the first air outlet 104, the first cavity 105 and the second cavity 106, and can be quickly disassembled and assembled with the lower housing 102; therefore, when the upper housing 101 and the lower housing 102 are separated, the third cavity 107 of the lower housing 102 can be exposed through the first mounting port to realize the putting in and emptying of kitchen waste.

[0027] In other embodiments, the connection method between the upper housing 101 and the lower housing 102 may also include plug-in or snap-fit, which is not limited here and depends on the actual needs.

[0028] Optionally, the upper housing 101 includes a first housing body 1011 and a support plate 1012; the first housing body 1011 has a first air inlet 103 and a first air outlet 104, and has a first cavity 105 and a second cavity 106 inside; the support plate 1012 is installed on one end of the first housing body 1011 facing the lower housing 102, and is used to connect with the lower housing 102 in a detachable manner; the support plate 1012 has a through-hole 10121, a second through-hole 10122 and a third through-hole 10123 along the thickness direction; the third cavity 107 is connected to the outlet of the hot air supply device 200 through the first through-hole 10121, and to the first cavity 105 through the second through-hole 10122, and to the second cavity 106 through the third through-hole 10123.

[0029] Specifically, such as Figure 3 , 4As shown, the first shell body 1011 is an injection molded part, with a first air inlet 103 and a first air outlet 104 at its top, a second mounting port 10111 at its bottom, and an internal first cavity 105, a second cavity 106, and a first fixing post 10114; as Figure 5 As shown, the support plate 1012 is provided with a second fixing post 10124. When the support plate 1012 is installed at the second mounting port 10111 of the first shell body 1011, the first fixing post 10114 and the second fixing post 10124 are aligned and fixedly connected by threaded parts. The support plate 1012 is provided with a first through port 10121, a second through port 10122 and a third through port 10123 along the thickness direction. The first through port 10121 connects the outlet of the hot air supply device 200 and the third cavity 107. The second through port 10122 connects the first cavity 105 and the third cavity 107. The third through port 10123 connects the second cavity 106 and the third cavity 107.

[0030] In this optional embodiment, the support plate 1012 is sandwiched between the first shell body 1011 and the lower shell 102, and is provided with a first through-hole 10121, a second through-hole 10122 and a third through-hole 10123. Therefore, the support plate 1012 can support the upper shell 101 on the lower shell 102 while realizing effective communication between the third cavity 107 and the outlet of the hot air supply device 200, the first cavity 105 and the second cavity 106.

[0031] Optionally, the food waste disposer also includes a grid plate 700, which is disposed on the first housing body 1011 and is used to cover the first air outlet 104.

[0032] Specifically, such as Figure 3 As shown, the top surface of the first housing body 1011 is provided with a first mounting groove 10112, and the grid plate 700 is disposed at the first mounting groove 10112 and is used to cover the first air outlet 104.

[0033] In this optional embodiment, the food waste disposer achieves multiple effects simultaneously—protection, dust prevention, and ensuring unobstructed airflow—by providing a grid plate 700 on the first housing 1011 that covers the first air outlet 104. The grid plate 700, covering the first air outlet 104, directly blocks external foreign objects (such as dust and small items) from entering the equipment, ensuring the cleanliness of the internal structure and stable operation. Simultaneously, the perforated structure of the grid plate 700 prevents blockage of the first air outlet 104, ensuring smooth airflow and not affecting the overall air circulation and drying efficiency of the equipment.

[0034] Optionally, the hot air supply device 200 includes a ventilation device 201 and a heating device 202 connected to each other; the ventilation end of the ventilation device 201 is connected to the first cavity 105 and the first air inlet 103; the air outlet of the ventilation device 201 is connected to the air inlet of the heating device 202, and the air outlet of the heating device 202 is fixed in the first through-hole 10121 and connected to the third cavity 107 through the first through-hole 10121.

[0035] Specifically, such as Figure 1 As shown, the exhaust device 201 and the heating device 202 are connected sequentially from top to bottom. The exhaust end (i.e., the upper end) of the exhaust device 201 is connected to the first cavity 105 and the first air inlet 103. The air outlet end (i.e., the lower end) of the exhaust device 201 is connected to the air inlet end (i.e., the upper end) of the heating device 202. The air outlet end (i.e., the lower end) of the heating device 202 is fixed in the first through-hole 10121 and is connected to the third cavity 107 through the first through-hole 10121.

[0036] In this optional embodiment, the exhaust end of the exhaust device 201 is directly connected to the first cavity 105 and the first air inlet 103, which can draw air from the outside or inside the first cavity 105, avoiding heat loss caused by turbulent airflow; the exhaust end of the exhaust device 201 is connected to the air inlet of the heating device 202, which can ensure that all the extracted air enters the heating device 202 for full heating, reducing the problem of unheated air mixing in and affecting the drying effect; and the exhaust end of the heating device 202 is fixed to the first through-hole 10121 and directly connected to the third cavity 107, which allows the heated hot air to reach the kitchen waste storage area without leakage, which not only solves the problem of hot air being discharged before acting on the kitchen waste, but also ensures the stability of hot air delivery.

[0037] Optionally, the food waste disposer also includes a control panel 800, which is mounted on the first housing body 1011; the control panel 800 is electrically connected to the hot air supply device 200.

[0038] Specifically, such as Figure 3 As shown, the top surface of the first housing body 1011 is provided with a second mounting groove 10113, and the control panel 800 is disposed in the second mounting groove 10113 and is used to electrically connect with the exhaust device 201 and the heating device 202 of the hot air supply device 200.

[0039] In this optional embodiment, the food waste disposer significantly improves the ease of operation and controllability of the drying process by providing a control panel 800 electrically connected to the hot air supply device 200 on the first housing body 1011. As the core of human-machine interaction, the control panel 800 allows users to operate directly on the housing surface without disassembling the device, such as turning the hot air supply device 200 on / off, adjusting the hot air temperature, or adjusting the drying time, thus solving the problem of cumbersome operation of traditional devices without a control panel 800.

[0040] Optionally, the food waste disposer also includes an air filter 300, which is disposed within the second cavity 106.

[0041] Specifically, the air filtration device 300 is an activated carbon filter element, which is detachably installed in the second cavity 106 and fits against the inner wall of the second cavity 106 to remove harmful impurities and odors from the air.

[0042] In this optional embodiment, during the drying process, air carrying odors, moisture, and small debris particles enters the second chamber 106 from the third chamber 107; the air filtration device 300 can filter this air here, removing harmful impurities and odors, preventing untreated polluted air from being directly discharged to the outside, which reduces pollution to the surrounding environment and reduces the impact of odor diffusion on users' lives. At the same time, it can also prevent impurities from clogging the first air outlet 104, indirectly ensuring the long-term stable operation of the whole machine.

[0043] Optionally, the food waste disposer also includes a water-blocking structure 400, which is disposed in the second cavity 106 and located on the side of the air filter device 300 facing the third cavity 107.

[0044] In this optional embodiment, the hot and humid air generated by drying kitchen waste in the third chamber 107 carries water vapor into the second chamber 106. If it directly contacts the air filter device 300, it can easily cause the adsorbent material to become damp and clump together, reducing its adsorption capacity. The water-blocking structure 400 can first block, guide, or preliminarily dehydrate the hot and humid air here, reducing the direct impact of water vapor on the air filter device 300 and preventing the filter material from failing or growing bacteria due to the high humidity environment. At the same time, the dry air after being blocked by the water can then enter the air filter device 300, allowing the adsorbent material to focus more on capturing odor molecules, improving the deodorization efficiency, and indirectly reducing the frequency and cost of replacing the filter element for users.

[0045] Optionally, the water-blocking structure 400 includes a first plate 401 and a second plate 402; the first plate 401 and the second plate 402 are disposed opposite to each other and spaced apart within the second cavity 106 along the depth direction of the second cavity 106; a portion of the first plate 401 forms a first passage 403 with the inner wall of the second cavity 106, and a portion of the second plate 402 forms a second passage 404 with the inner wall of the second cavity 106; the projection of the second passage 404 on the first plate 401 is located within the outline of the first plate 401.

[0046] Specifically, such as Figure 6 As shown, both the first plate 401 and the second plate 402 extend horizontally and are positioned opposite each other and spaced apart within the second cavity 106 along the depth direction (i.e., the vertical direction). The spacing between them is not specifically limited and can be determined according to actual needs. The left end of the first plate 401 forms a first passage 403 with the inner wall of the second cavity 106, and the right end of the second plate 402 forms a second passage 404 with the inner wall of the second cavity 106. The projection of the second passage 404 on the first plate 401 is located within the outline of the first plate 401.

[0047] In this optional embodiment, the first plate 401 and the second plate 402 are spaced apart along the depth direction of the second cavity 106, and form airflow paths with the inner wall of the second cavity 106 through the first passage 403 and the second passage 404, respectively. This layered structure allows the humid and hot air entering from the third cavity 107 to first contact the second plate 402, initially blocking some water vapor and changing the airflow direction. At the same time, the projection of the second passage 404 on the first plate 401 is completely within the outline of the first plate 401, so that the airflow passing through the first passage 403 must bypass the second plate 402 again before entering the second passage 404. This prolongs the flow path and residence time of the airflow in the water-blocking structure 400, allowing more water vapor to condense and separate due to collision with the plate wall, avoiding a large amount of water vapor directly entering the air filter device 300 and causing it to become damp and fail, thereby more stably ensuring the deodorization performance and service life of the air filter device 300.

[0048] Optionally, the food waste disposer further includes a first connecting structure 500 and a second connecting structure 600. The first connecting structure 500 is disposed on the end face of the first plate 401 facing the second plate 402, and the second connecting structure 600 is disposed on the end face of the second plate 402 facing the first plate 401. The first connecting structure 500 and the second connecting structure 600 are detachably connected.

[0049] Specifically, such as Figure 4 As shown, the first connecting structure 500 is a first connecting post disposed on the end face of the first plate 401 facing the second plate 402; as Figure 6As shown, the second connecting structure 600 is a second connecting post disposed on the end face of the second plate 402 facing the first plate 401, and the second connecting post is provided with a first slot structure for the first connecting post to be inserted.

[0050] In this optional embodiment, the first plate 401 and the second plate 402 are detachably connected by a connection structure arranged in opposite directions. When the water-blocking structure 400 has been used for a long time, dirt or residual garbage may adhere to the surface of the plate due to water vapor condensation. The user can disassemble the second plate 402 for cleaning, avoiding the complicated operation of disassembling the whole structure. At the same time, if the second plate 402 is damaged, it is not necessary to replace the entire water-blocking structure 400, but only to replace it separately, which reduces maintenance costs.

[0051] In other embodiments, the first connecting structure 500 is a third connecting post disposed on the end face of the first plate 401 facing the second plate 402, and the third connecting post is provided with a second slot structure; the second connecting structure 600 is a fourth connecting post disposed on the end face of the second plate 402 facing the first plate 401, and the fourth connecting post is inserted into the second slot structure.

[0052] Optionally, the lower shell 102 includes a second shell body 1021 and an inner cylinder 1022; the inner cylinder 1022 is located inside the second shell body 1021 and is provided with a third cavity 107; the outer wall of the inner cylinder 1022 and the inner wall of the second shell body 1021 form a return air duct 1023; the inner cylinder 1022 is provided with a plurality of fourth through holes 10221, and the fourth through holes 10221 connect the return air duct 1023 and the third cavity 107.

[0053] Specifically, such as Figure 7 As shown, the second shell body 1021 is an injection molded part, which is a cavity structure with an open top. The inner cylinder 1022 is located inside the second shell body 1021 and is provided with a third cavity 107. When the inner cylinder 1022 is located inside the second shell body 1021, the side wall of the inner cylinder 1022 and the side wall of the second shell body 1021, as well as the bottom wall of the inner cylinder 1022 and the bottom wall of the second shell body 1021, form a return air duct 1023. The side wall and bottom wall of the inner cylinder 1022 are respectively provided with a plurality of fourth through holes 10221, which connect the return air duct 1023 and the third cavity 107, thereby realizing the flow of hot air between the return air duct 1023 and the third cavity 107.

[0054] In this optional embodiment, the inner cylinder 1022 separates the third cavity 107 from the return air duct 1023, while connecting the two through multiple fourth through holes 10221, allowing hot air to circulate within the third cavity 107, avoiding uneven drying due to insufficient hot air in local areas, and further improving the overall drying efficiency and effect.

[0055] Optionally, the inner bottom wall of the second shell body 1021 is provided with a first support member 10211, and the inner cylinder 1022 is provided with a fixing groove 10222 that cooperates with the first support member 10211. Part of the first support member 10211 is supported in the fixing groove 10222, so that the bottom of the inner cylinder 1022 and the inner bottom wall of the second shell body 1021 form part of the return air duct 1023.

[0056] Specifically, such as Figure 6 As shown, a first support member 10211 protrudes from the middle of the inner bottom wall of the second shell body 1021. The shape of the first support member 10211 is not specifically limited and can be selected according to actual needs; for example... Figure 8 As shown, the bottom end of the inner cylinder 1022 is provided with a fixing groove 10222. The upper part of the first support member 10211 is supported in the fixing groove 10222 and is adapted to the shape of the fixing groove 10222. The bottom of the inner cylinder 1022 and the inner bottom wall of the second shell body 1021 form part of the return air duct 1023.

[0057] In this optional embodiment, the first support member 10211 is partially embedded in the fixing groove 10222 of the inner cylinder 1022, which can form a precise positioning and stable support for the inner cylinder 1022 placed inside the second shell body 1021. At the same time, this support method allows a gap to be naturally formed between the bottom of the inner cylinder 1022 and the inner bottom wall of the second shell body 1021. This gap directly constitutes part of the return air duct 1023, eliminating the need for additional complex air duct separation structures. This simplifies the overall assembly process of the lower shell 102, ensures the unobstructed flow of the return air duct 1023, guarantees the integrity of the hot air circulation path, and further improves the hot air utilization rate and drying efficiency.

[0058] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
