Detailed implementation manners
[0027] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the protection scope of the present application.
[0028] Figure 1 An example of the kitchen waste treatment device is schematically shown in a sectional view. The kitchen waste treatment device includes a crushing unit 1 and a drying unit 2 that are connected and communicated. Here, the connection and communication means that the waste crushed by the crushing unit 1 can enter the drying unit 2 for subsequent treatment.
[0029] The drying unit 2 includes a drying chamber 20, a heating assembly, a discharge channel, a liquid detector and a controller. Among them, the drying chamber 20 is used to receive the waste crushed by the crushing unit 1. Since liquid is generated during the crushing process and flows into the drying chamber 20, if the heating program is started for drying at this time, the drying efficiency is low and it is not energy-saving.
[0030] Therefore, after the shredded garbage enters the drying chamber 20, first wait for the liquid to be completely drained from the discharge channel. A liquid detector is provided for detecting the water flow rate of the discharge channel, and the detection result will be sent to the controller. After the water flow rate is less than the first preset value, the controller controls the heating component to start working. The first preset value should be a water flow rate value or range close to zero, which is not limited here. It can be understood that after the water flow rate is less than the first preset value, there is no or only very little visible liquid in the drying chamber 20. This drying method of starting heating after the liquid is drained effectively improves the drying efficiency and energy-saving effect.
[0031] According to an exemplary embodiment of the present application, as Figure 2 shown, the discharge channel includes a liquid discharge channel 21 and a slag discharge channel 22 separately provided at the bottom of the drying chamber 20. The liquid detector is arranged close to the liquid discharge channel 21, which is beneficial to improving the accuracy of water flow rate detection.
[0032] Further, as Figure 3 shown, the liquid discharge channel 21 includes a drain hole 211 and a thimble 212 corresponding to the drain hole 211. Among them, the thimble 212 is configured to be movable up and down to dredge the drain hole 211 to prevent the drain hole 211 from being blocked by relatively small garbage. Specifically, the thimble 212 is located below the drain hole 211 and can be driven by a motor to move up and down. When in the lower position, the drain hole 211 is completely opened for drainage. When in the higher position, the thimble 212 extends upward into the drain hole 211 to dredge it. In addition, when the heating component is working, the thimble 212 is always in the higher position to block the drain hole 211 to avoid unnecessary blockage.
[0033] In one example, the liquid detector is an infrared detector and is at least arranged in at least one of the above drain holes 211. The infrared detector includes at least one infrared emission end and an infrared receiving end, which are respectively arranged on opposite sides of the hole wall of the drain hole 211. When water flows through the drain hole 211, the signal emitted by the infrared receiving end is interfered and changed. The red hair emission end receives the interfered signal and transmits it to the controller, indicating that the water flow rate at this stage is still greater than the first preset value. When the water flow rate is less than the first preset value or there is no more water flowing, the signal emitted by the infrared receiving end is not sufficient to be interfered. The red hair emission end receives the normal signal and transmits it to the controller, indicating that the heating component can be controlled to start working.
[0034] According to an exemplary embodiment of the present application, in order to more accurately know when the expected effect is achieved, the drying unit 2 further includes a humidity sensor. The humidity sensor can be arranged on the inner wall of the drying chamber 20 for detecting the humidity in the drying chamber 20 and sending it to the controller. After the humidity is less than the second preset value, the controller controls the heating component to stop working.
[0035] Because different types of garbage have varying moisture contents, setting the humidity to a fixed second preset value as described above does not ensure that each type of garbage reaches its optimal dryness. Therefore, in another example, the humidity sensor is configured to periodically detect the humidity within the drying chamber 20 and transmit this information to the controller. The controller then controls the heating assembly to stop operating when the difference between two adjacent humidity readings falls below a third preset value. This determination is based on whether the humidity measured at two adjacent time points remains constant or changes very little, which helps improve the intelligence and accuracy of the control.
[0036] According to an exemplary embodiment of the present application, the slag discharge channel 22 is configured to open after the heating assembly stops working, and the dried garbage is discharged from the drying chamber 20 through the slag discharge channel 22 .
[0037] According to an exemplary embodiment of the present application, Figure 2 As shown, the drying chamber 20 also includes a stirring assembly 23, which is driven by a motor to rotate and stir the garbage in the drying chamber 20 when the heating assembly is operating or when the slag discharge channel 22 is open. On the one hand, stirring the garbage during heating can accelerate the drying process and improve the drying effect; on the other hand, stirring the garbage after the slag discharge channel 22 is opened can cause the garbage to be discharged through the slag discharge channel 22.
[0038] According to an exemplary embodiment of the present application, Figure 4 As shown, the drying unit includes a gas circulation pipeline connected to the drying chamber 20. The gas circulation pipeline includes a fan 24, a condensing assembly 25, and a deodorizing module 26, which are arranged in this order. During the drying process, the hot and humid gas generated in the drying chamber 20 enters the condensing assembly 25 via the fan 24. After passing through the condensing assembly 25, the heat and moisture of the gas are exchanged. The dry and cold air is then deodorized by the deodorizing module 26 and re-enters the drying chamber 20, completing the cycle.
[0039] Furthermore, the condensation component 25 includes a condensation fan 251 for bringing in external cold air and a condensation water channel 252 for discharging condensed water; the deodorization module 26 can be an ozone generator or a carbon box.
[0040] According to an exemplary embodiment of the present application, Figure 1 As shown, the pulverizing unit 1 includes a centrifugal drum 11 above a drying chamber 20 and a retaining ring 12 surrounding the centrifugal drum 11. The centrifugal drum 11 is driven by a motor to rotate at high speed. A plurality of through holes are provided on its wall. The waste in the drum is pulverized by centrifugal force and brushed out of the centrifugal drum. The brushed out waste is blocked by the retaining ring 12 and falls into the drying chamber 20.
[0041] According to an exemplary embodiment of the present application, Figure 1As shown, the kitchen waste treatment device further includes a storage cavity 3 located above the crushing unit 1, and the storage cavity 3 is configured to store and transport the waste to the crushing unit 1.
[0042] Components of different embodiments can be combined with each other in any feasible way to achieve the purpose of this application.
[0043] It should be additionally noted that this application should not be construed as limited to the embodiments described above, but should be construed as covering all possible implementation cases determined by the combination of the claims of this application and the content disclosed in the specification. Therefore, any simple modifications, equivalent changes and decorations made to the above embodiments based on the technical essence of this application without departing from the technical solution of this application all fall within the protection scope of the technical solution of this application.
