Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste, and particularly to a household kitchen waste treatment and drying machine. Background Art

[0002] Kitchen waste has a complex composition, mainly being a mixture of various substances such as oil, water, fruit peels, vegetables, rice and noodles, fish, meat, bones, as well as waste tableware, plastics, paper towels, etc. Its characteristics are that it is extremely prone to rot and deteriorate, emit a foul smell, and spread bacteria and viruses. After proper treatment and processing, it can be transformed into new resources. Its characteristic of high organic matter content enables it to be used as fertilizer and feed after strict treatment, and can also produce biogas for fuel or power generation. The oil part can be used to prepare biofuels.

[0003] Chinese Patent Application No.: CN202021929488.3, Patent Name: Household Kitchen Waste Dehydration and Degradation Machine, discloses a household kitchen waste dehydration and degradation machine, including a frame. A scraping filter is installed inside the frame. A degradation chamber is arranged on one side of the frame. A condenser is arranged on the frame above the degradation chamber. The scraping filter is provided with a feed inlet, a waste water drain outlet, and a waste residue discharge outlet. The waste residue discharge outlet is connected to the feed inlet of the degradation chamber. An exhaust port is arranged above the degradation chamber, and the exhaust port is connected to the air inlet of the condenser. The drain outlet at the bottom of the condenser is connected to the waste water drain outlet, and the condenser is provided with an exhaust port. This utility model can be used as fertilizer for cultivating flowers and plants after dehydrating and degrading household kitchen waste; it completely solves the resource treatment and harmless treatment of kitchen waste.

[0004] However, in the actual sales and use process, since the kitchen waste inside it cannot be stirred, when in use, the phenomenon of bottom sticking often occurs. And if a stirring mechanism is added inside the degradation chamber, it will be damaged due to receiving more heat during the stirring process. Moreover, the degradation chamber itself has a lot of dirt and needs to be cleaned after being used for a period of time. And if electrical components are set, it will cause inconvenience in cleaning.

[0005] Therefore, it is necessary to design a household kitchen waste treatment and drying machine that can stir the kitchen waste in the degradation chamber to avoid the occurrence of bottom sticking, and does not need to set electrical components, which is convenient for cleaning the degradation chamber.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment: The present invention provides a household kitchen waste treatment and drying machine, as Figures 1-14As shown in the figure, it includes a housing 1 and a heating box 2, a degradation bin 3, a locking mechanism 4, a water vapor treatment mechanism 5, a dehydration extrusion mechanism 6 and a rotation drive mechanism 7 installed in the housing 1. The degradation bin 3 is inserted into the heating box 2 in a horizontally pullable manner. The locking mechanism 4 is used to fixedly install the degradation bin 3 in the heating box 2. The top of the degradation bin 3 has an open structure. The heating box 2 is provided with a feed inlet connected to the dehydration extrusion mechanism 6. The dehydration extrusion mechanism 6 is used to extrude and convey food waste into the heating box 2. The dehydration extrusion mechanism 6 is provided with a drain pipe 6a, and the drain pipe 6a is used to discharge the garbage water extruded by the dehydration extrusion mechanism 6, so that the food waste entering the heating box 2 can reduce moisture. The top of the heating box 2 is provided with an air inlet and an air outlet. Among them, the air outlet is connected to the suction port of the water vapor treatment mechanism 5. The water vapor treatment mechanism 5 is used to discharge the water vapor evaporated in the degradation bin 3 outside the housing 1. The air inlet is used to supplement the gas sucked away by the water vapor treatment mechanism 5, so that the pressure inside the degradation bin 3 can be stabilized. A rotatable stirring rod 3a is arranged in the degradation bin 3. One end of the stirring rod 3a passes through the inside of the degradation bin 3 and is horizontally inserted into the rotation drive mechanism 7. By controlling the rotation drive mechanism 7 to work, the rotation drive mechanism 7 drives the stirring rod 3a to rotate, and the stirring rod 3a will stir the food waste inside the degradation bin 3 to avoid the occurrence of the bottom sticking phenomenon. And by only arranging the stirring rod 3a, without using electrical components, it is convenient to directly wash the degradation bin 3 later.

[0034] When installing the degradation bin 3, there will be the following problems. First, how can the degradation bin 3 be clamped with the rotary drive mechanism 7 during the installation process? Second, how to determine whether the position of the horizontal push of the degradation bin 3 is accurate? Third, how can the rotary drive mechanism 7 pass through the heating box 2 to establish a connection with the degradation bin 3? To solve these three problems, a conical column 3b is fixedly arranged at the end of the stirring rod 3a, and a clamping column 3c is fixedly arranged perpendicular to the axis of the conical column 3b. A sleeve 7c is fixedly connected to the output end of the rotary drive mechanism 7. The conical column 3b is horizontally slidably inserted into the sleeve 7c. A notch 7c1 for the clamping column 3c to be inserted is formed on the wall surface of the sleeve 7c. A shaft seat 7a is fixedly arranged on the heating box 2. One end of the sleeve 7c passes through the shaft seat 7a and is inserted into the heating box 2, that is, a connection is established between the rotary drive mechanism 7 passing through the heating box 2 and the degradation bin 3, and the sleeve 7c is rotatably connected to the shaft seat 7a. When the rotary drive mechanism 7 drives the sleeve 7c to rotate, the sleeve 7c will drive the clamping column 3c to rotate, so that the clamping column 3c drives the stirring rod 3a to rotate through the conical column 3b, that is, the stirring rod 3a can stir the kitchen waste inside the degradation bin 3. During the process of inserting the degradation bin 3, the degradation bin 3 drives the sleeve 7c to rotate continuously. When the user inserts it, if it is felt that the stirring rod 3a is driven to rotate, it means that the stirring rod 3a is connected to the rotary drive mechanism 7, that is, the problem of how the degradation bin 3 can be clamped with the rotary drive mechanism 7 during the installation process is solved.

[0035] In order to solve the problem of how to determine whether the position of the horizontal push of the degradation bin 3 is accurate, a positioner 8 is fixedly arranged on the heating box 2. The positioner 8 includes a microswitch 8a, a trash can thimble 8b, a washer 8c, a thimble bracket 8d, a positioning flap 8e and a snap ring 8f. The positioning flap 8e, the thimble bracket 8d and the microswitch 8a are all fixedly installed on the heating box 2. One end of the trash can thimble 8b contacts the sensing end of the microswitch 8a. The trash can thimble 8b is slidably connected to the thimble bracket 8d. The washer 8c is clamped inside the positioning flap 8e. The snap ring 8f is fixedly installed on the trash can thimble 8b. The other end of the trash can thimble 8b passes through the washer 8c and contacts the degradation bin 3. A convex block 3h that contacts the trash can thimble 8b is fixedly arranged on the degradation bin 3. The snap ring 8f is fixedly installed on the outer edge of the trash can thimble 8b. When the end of the trash can thimble 8b contacts the sensing end of the microswitch 8a, the snap ring 8f fits with the washer 8c, and the trash can thimble 8b is limited by the elastic force of the sensing end of the microswitch 8a to prevent the trash can thimble 8b from shaking. During the pushing process of the degradation bin 3, when the convex block 3h pushes the trash can thimble 8b, the microswitch 8a will sense the movement of the trash can thimble 8b. At this time, the microswitch 8a transmits a signal to the controller, and the indicator light on the housing 1 will turn green. The user can move by pushing the locking mechanism 4, so that the locking mechanism 4 locks the degradation bin 3, that is, to determine whether the position of the horizontal push of the degradation bin 3 is accurate.

[0036] The degradation bin 3 includes a box body 3d, a box cover 3e and a stirring shaft 3f. A discharge port 3d1 is opened at the top of the box body 3d. The discharge port 3d1 is the opening structure at the top of the degradation bin 3. The box cover 3e is fixedly installed on the box body 3d. One end of the stirring shaft 3f is rotatably connected to the box cover 3e. The other end of the stirring shaft 3f passes through the box body 3d and is rotatably connected to it. A plurality of stirring rods are arranged along the axial direction of the stirring shaft 3f. Three bayonets 3e1 are fixedly arranged on the box cover 3e. The locking mechanism 4 is fixedly connected to the degradation bin 3 through the three bayonets 3e1. The three are distributed in a triangle along the outer edge of the box cover 3e. The convex block 3h is located on the outer wall of the box body 3d. Driving the stirring shaft 3f to rotate through the rotation driving mechanism 7 will cause the stirring shaft 3f to drive a plurality of stirring rods to stir the kitchen waste. After the degradation bin 3 is taken out and the garbage inside the degradation bin 3 is cleaned, the garbage is led out along the discharge port 3d1 instead of opening the 3e. And after the garbage is poured out, by adding water into the box body 3d for flushing and pouring out the cleaned water, the cleaning of the degradation bin 3 can be realized.

[0037] When the dryer is working, the discharge port of the dehydration and extrusion mechanism 6, the air inlet and the air outlet of the water vapor treatment mechanism 5 are all located above the discharge port 3d1, so that the kitchen waste can be added into the box body 3d along the discharge port 3d1, and the water vapor generated by heating can pass through the discharge port 3d1 and be sucked away along the water vapor treatment mechanism 5.

[0038] Two temperature sensing devices 9 are fixedly arranged on the heating box 2. The two temperature sensing devices 9 are used to detect the temperature of the kitchen waste inside the degradation bin 3. Each temperature sensing device 9 includes a temperature electrode 9a, a guide post 9b, a spring 9c, a temperature electrode nut 9d and a rear contact bracket 9e. The rear contact bracket 9e is fixedly installed on the heating box 2. The guide post 9b is slidably installed on the rear contact bracket 9e horizontally. The spring 9c is used to provide an elastic force for the guide post 9b to approach the degradation bin 3. The temperature electrode nut 9d is fixedly installed at the end of the guide post 9b. One end of the temperature electrode 9a is a conical structure, and a stud meshing with the temperature electrode nut 9d is arranged at the other end of the temperature electrode 9a. An insertion hole for the end of the temperature electrode 9a to insert is formed on the degradation bin 3. By setting the end of the temperature electrode 9a into a conical shape, the insertion hole of the degradation bin 3 can be sealed to prevent the kitchen waste from discharging along the insertion hole. And the spring 9c can push the temperature electrode 9a to closely fit on the degradation bin 3. The temperature electrode 9a is connected to the controller through a signal wire. The two temperature sensing devices 9 can detect the temperature inside the degradation bin 3 at multiple points. When the temperature of the kitchen waste is relatively high, it is necessary to control the heating box 2 to cool down to avoid the risk of overheating.

[0039] The heating box 2 includes a heater 2a, a heat conducting arc plate 2b, a material guiding arc plate 2c and a housing 2d. The heater 2a is fixedly installed inside the housing 1. The internal cavity of the heater 2a is a waist-shaped structure. The material guiding arc plate 2c is fixedly installed at the top of the cavity. The heat conducting arc plate 2b is fixedly installed at the bottom of the cavity. The heater 2a is fixedly installed on the outer edge of the heat conducting arc plate 2b. The heat conducting arc plate 2b is used to conduct the heat generated by the heater 2a to the box body 3d. A heat dissipation hole for the heater 2a to pass through is formed at the bottom of the housing 2d. Two box bodies 3d are arranged on both sides of the box body 3d. The box body 3d is used to avoid the ends of the material guiding arc plate 2c and the heat conducting arc plate 2b, so as to prevent the ends of the material guiding arc plate 2c and the heat conducting arc plate 2b from warping and blocking the degradation bin 3 when the degradation bin 3 is inserted. When the box body 3d is inserted into the material guiding arc plate 2c and the heat conducting arc plate 2b, the heat generated by the heating of the heater 2a will be transferred to the groove 3d2 through the heat conducting arc plate 2b. Both the heat conducting arc plate 2b and the material guiding arc plate 2c adopt a thin plate structure with a thickness of 1 mm, so that the heat transfer speed is fast and the energy loss is less. The material guiding arc plate 2c and the heat conducting arc plate 2b adopt a split structure, mainly to prevent the heat from being transferred to the material guiding arc plate 2c. Since there is no kitchen waste in the area of the degradation bin 3 covered by the material guiding arc plate 2c and there is no need for heating, energy can be saved.

[0040] The rotation drive mechanism 7 further includes a drive motor 7b, a motor mounting base 7e, and a cooling fan 7f. The output end of the drive motor 7b is fixedly connected to the bushing 7c. The drive motor 7b is fixedly mounted on the housing 1 through the motor mounting base 7e. The cooling fan 7f is located at the tail of the drive motor 7b. The cooling fan 7f is used to discharge the heat generated by the drive motor 7b out of the housing 1. The housing 1 is provided with ventilation holes for the airflow of the cooling fan 7f to pass through. When the drive motor 7b is rotating, it will generate a lot of heat. By using the cooling fan 7f for heat dissipation, the heat can be discharged, increasing the service life of the drive motor 7b.

[0041] As Figure 4 shown, a water seal ring 7d is provided on the outer edge of the bushing 7c. A snap ring 3d3 is fixedly provided on the box body 3d. The snap ring 3d3 is sleeved on the outer edge of the tapered column 3b. When the bushing 7c is clamped with the tapered column 3b, the end of the bushing 7c is inserted into the snap ring 3d3. The water seal ring 7d is located between the bushing 7c and the snap ring 3d3. The outer edge of the water seal ring 7d contacts the water seal ring 7d3, and the inner edge of the water seal ring 7d contacts the bushing 7c. By providing the water seal ring 7d, it is possible to prevent water vapor from passing through the water seal ring 7d and entering the equipment, protecting the safety of the equipment.

[0042] During use, the user inserts the degradation bin 3 into the heating box 2. In the final stage of the insertion process of the degradation bin 3, the clamping post 3c will be clamped with the notch 7c1. At the same time, the tapered column 3b will touch the trash can thimble 8b, enabling the micro switch 8a to generate a signal and transmit it to the controller, and the green indicator light on the housing 1 will light up. At this time, the user fixes the degradation bin 3 through the locking mechanism 4. After the preparation work is completed, the equipment starts to work. The kitchen waste is pushed into the degradation bin 3 after being extruded by the dehydration and extrusion mechanism 6, and then the heating box 2 heats the degradation bin 3. At the same time, the rotation drive mechanism 7 drives the stirring rod 3a to rotate, so that the water in the kitchen waste is evaporated, and then the water vapor treatment mechanism 5 inhales the water vapor into the sewer pipe. During the heating process of the heating box 2, the temperature sensing device 9 senses the temperature inside the heating box 2 to prevent the inside of the heating box 2 from overheating.

[0043] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
