Description

Technical Field

[0001] This utility model relates to the field of kitchen waste disposers, and in particular to a water-air separation kitchen waste disposer. Background Technology

[0002] Food waste disposers work by heating and stirring food waste to dry it or ferment it into organic fertilizer. Household food waste disposers often have a purification device to prevent the direct emission of odors generated during the heating process. Existing food waste disposers typically include a filter cartridge installed in the air duct and a fan connected in series at the front or rear of the filter cartridge. The fan draws odors from inside the disposer into the air duct and filters them through the filter cartridge, thus achieving purification.

[0003] However, during the heating process of food waste, the moisture in the food waste evaporates, producing gas with a high water vapor content. As the gas passes through a long air duct, condensation occurs due to the gradual decrease in gas temperature. Some of the condensation remains in the air duct, while the rest is carried out of the food waste processor by the gas. The condensation remaining in the air duct cannot be discharged and will accumulate over time, breeding bacteria, causing pollution, and making cleaning difficult. Furthermore, the high-temperature gas carrying condensation can easily invade the electrical components of the fan when passing through it, damaging the fan and resulting in poor reliability and stability, and a high failure rate.

[0033] 8. Inner tub. Detailed Implementation

[0034] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0035] A water-air separation food waste disposer, such as Figures 1 to 7 As shown, the device includes an outer tub 7, an inner tub 8, and a purification device. The inner tub 8 is movably installed inside the outer tub 7. The purification device includes a fan 6, a purification duct, and at least one filter element 5. The first end of the purification duct is connected to the inner tub 8, and the second end of the purification duct is connected to the atmosphere. The fan 6 is connected to the purification duct, and the filter element 5 is disposed inside the purification duct. The purification duct includes a filter channel, a condensation collection chamber 111, and an exhaust duct 141. The inner tub 8 is connected to the filter channel, the filter channel is connected to the condensation collection chamber 111, the condensation collection chamber 111 is connected to the air inlet of the fan 6, the air outlet of the fan 6 is connected to the exhaust duct 141, the exhaust duct 141 is connected to the atmosphere, the filter element 5 is disposed inside the filter channel, the condensation collection chamber 111 is located below the filter channel and the exhaust duct 141, and a drain outlet 121 is provided at the lower part of the condensation collection chamber 111. The drain outlet 121 is sealed with a drainage device.

[0036] Traditional food waste disposers cannot achieve water-air separation in their purification devices. This results in the high-temperature, high-humidity gas generated during the heating of food waste passing directly through the fan 6. The fan 6 operates in this high-temperature, high-humidity environment for extended periods, leading to a high failure rate, short lifespan, and poor reliability and stability. Furthermore, due to the long length of the purification duct, the high-temperature, high-humidity gas gradually cools and condenses during its flow. This condensate adheres to the inner wall of the duct, is difficult to drain, and accumulates over time, easily breeding bacteria and becoming difficult to clean. This invention addresses this by using a condensation collection chamber 111 to condense the high-temperature, high-humidity gas filtered by the filter element 5, thus separating water and air and preventing water from entering the fan 6. The fan 6 is located at the end of the purification duct; the gas cools down after passing through the filter element 5 and the condensation collection chamber 111, preventing the high-temperature gas from causing the fan 6 to overheat, extending its lifespan, reducing the failure rate, and improving reliability and stability. A drainage device drains the condensate from the condensation collection chamber 111, preventing it from accumulating and overflowing into the fan 6, thus preventing bacterial growth and facilitating cleaning.

[0037] Specifically, the drainage device includes a drain valve 2 and a drain switch 3 for opening and closing the drain valve 2. The drain valve 2 is fixedly installed at the drain outlet 121, and the drain switch 3 abuts against the drain valve 2. By sealing the drain outlet 121 with the drain valve 2, the negative pressure of the purification duct is prevented from decreasing due to the drain outlet 121 being open. When it is necessary to drain condensate, the drain valve 2 is opened by pressing the drain switch 3, thereby releasing the drain outlet 121 and allowing the condensate to be discharged from the condensate collection chamber 111 for easy cleaning.

[0038] Specifically, the drain valve 2 includes a valve body 21, a valve core 22, a sealing plug 23, and a drain spring 24. The valve body 21 is located at the lower part of the condensate collection chamber 111 and below the drain outlet 121. The valve core 22 is slidably installed inside the valve body 21. The sealing plug 23 is fixedly installed at the upper end of the valve core 22 and seals against the drain outlet 121. The drain spring 24 is sleeved on the outside of the valve body 21 and abuts against the lower part of the valve core 22. The lower part of the valve core 22 abuts against the drain switch 3. The valve core 22 moves up and down within the valve body 21, causing the sealing plug 23 to press against the sealing drain port 121. When sealing the drain port 121, the drain switch 3 presses upward against the valve core 22, causing the sealing plug 23 to press against the sealing drain port 121. When opening the drain port 121, the drain switch 3 is released, and the drain spring 24 presses against the valve core 22 and moves downward, causing the sealing plug 23 to move away from the drain port 121, thereby releasing the drain port 121. Condensate flows out from the drain port 121 through the valve body 21. The structure is simple and the cost is low.

[0039] Specifically, the drain switch 3 includes a switch base 31, a switch rocker 32, and a switch spring 33. The switch base 31 is fixedly installed at the lower part of the condensate collection chamber 111. The middle part of the switch rocker 32 is hinged to the switch base 31. The first end of the switch rocker 32 is the trigger end 321, and the second end of the switch rocker 32 is the control end 322. The trigger end 321 is located below the valve core 22 and abuts against the valve core 22. The switch spring 33 is disposed between the condensate collection chamber 111 and the control end 322 and abuts against the upper part of the control end 322. In the initial state, under the action of the switch spring 33, the trigger end 321 of the switch rocker 32 rotates upward to abut against the valve core 22, thereby sealing the drain outlet 121. When it is necessary to drain condensate, by pressing the control end 322 upward, the switch spring 33 is compressed, and the trigger end 321 rotates downward to release the valve core 22. The valve core 22 moves downward under the action of the drain spring 24, thereby opening the drain outlet 121.

[0040] Specifically, the upper end of the valve core 22 is provided with a connecting protrusion 221, and the sealing plug 23 is sleeved on the connecting protrusion 221. The lower part of the valve core 22 is provided with a limiting step 222, which is located below the valve body 21 and engages with the valve body 21. The drain spring 24 abuts against the limiting step 222. The lower end of the valve core 22 is provided with a trigger protrusion 223, which abuts against the trigger end 321 of the switch rocker 32. The connecting protrusion 221 connects to the sealing plug 23, which facilitates the installation and removal of the sealing plug 23, aids in later maintenance, and reduces maintenance costs. The limiting step 222 limits the valve core 22 and simultaneously fixes the drain spring 24. The trigger protrusion 223 reduces the contact area between the valve core 22 and the switch rocker 32, preventing jamming and reducing obstruction of condensate, thereby increasing the drainage speed.

[0041] Specifically, a water collection box 4 is movably installed at the lower part of the outer tub 7, and the water collection box 4 is located below the drain outlet 121. Condensate is discharged into the water collection box 4 for temporary storage. After the condensate in the condensate collection chamber 111 is completely drained, the drain valve 2 is closed, and then the water collection box 4 is disassembled for cleaning to prevent condensate from being discharged directly and to avoid secondary pollution. The water collection box 4 adopts a drawer-type installation structure.

[0042] Specifically, a trigger port 41 is provided on one side of the water receiving box 4, penetrating the water receiving box 4. The control end 322 of the switch rocker 32 is located above the trigger port 41, and a control button 323 is provided at the lower part of the control end 322. The control button 323 is inserted into the trigger port 41. The trigger port 41 protects and hides the control button 323, preventing accidental activation due to leakage of the control button 323. When drainage is required, insert your finger into the trigger port 41 and press the control button 323 upward to open the drain valve 2. After drainage is completed, release the control button 323 and simultaneously hook the trigger port 41 to pull the water receiving box 4 outward for cleaning. The operation is convenient.

[0043] Specifically, the outer barrel 7 includes an inner shell 71 and an outer shell 72.

The power chamber is located on the rear side of the condensation collection chamber 111. The fan 6 is fixedly installed in the power chamber. A drainage device is provided in the lower part of the filter seat 1. The upper part of the filter seat 1 is provided with an exhaust duct 141 and at least one mounting groove 113. The rear side of the exhaust duct 141 is open and abuts against the side wall of the outer shell 72. The outer shell 72 has multiple exhaust holes 721 corresponding to the position of the exhaust duct 141. The bottom of the mounting groove 113 has multiple arc-shaped filter holes 114 communicating with the condensation collection chamber 111. The lower part of the filter element 5 is inserted into the mounting groove 113. The condensation collection chamber 111 and the exhaust duct 141 are both integrated on the filter base 1, and the filter element 5 is directly installed on the filter base 1, making the structure more compact, reducing the installation space occupied, and reducing the overall size of the machine.

[0044] Specifically, the filter base 1 includes a base body 11, a bottom cover 12, a fixed cover plate 13, and an exhaust hood 14. The bottom of the base body 11 is open, the bottom cover 12 is fixedly installed on the bottom of the base body 11, a drainage device is provided at the lower part of the bottom cover 12, a condensation collection chamber 111 is provided inside the base body 11, a power groove 112 is provided at the rear of the base body 11, the fixed cover plate 13 is provided on the power groove 112, the power groove 112 and the fixed cover plate 13 enclose to form a power cavity, a fan outlet 115 is provided at the upper part of the power cavity, the exhaust hood 14 is fixedly installed on the upper part of the base body 11, the rear side of the exhaust hood 14 is open and abuts against the side wall of the outer shell 72, the exhaust hood 14 and the outer shell 72 enclose to form an exhaust duct 141, and the exhaust duct 141 is connected to the fan outlet 115. The valve body 21 is directly formed on the bottom cover 12, reducing the number of parts and lowering costs. The fan 6 is fixed by the fixing cover plate 13, and the exhaust hood 14 is integrally formed with the fixing cover plate 13, thereby simplifying the assembly process.

[0045] Specifically, the purification device is equipped with two filter elements 5. The upper part of the filter base 1 is provided with two mounting slots 113.

The upper ends of the two filter elements 5 are respectively connected to the two sides of the diversion chamber 731. The air inlet chamber 732 is connected to the inner barrel 8. A temperature and humidity sensor 734 is provided in the diversion channel 733. The two parallel filter elements 5 are set to increase the purification effect. The high temperature and high humidity gas in the inner barrel 8 first enters the air inlet chamber 732, and then enters the diversion chamber 731 through the diversion channel 733. The narrow diversion channel 733 can increase the wind speed and increase the contact area between the temperature and humidity sensor 734 and the gas, thereby improving the measurement accuracy. The gas then enters the two filter elements 5 from the diversion chamber 731 for purification and filtration, and finally gathers in the condensation and collection chamber 111. The condensation and collection chamber 111 has a relatively large volume, which can reduce the flow rate and increase the air pressure, further cooling and condensing the gas. The fan 6 is located on the side of the condensation and collection chamber 111, not at the bottom, so the condensate will not enter the fan 6.
