Description
Technical Field
[0001] The present application relates to a food waste disposer, and in particular to a metal detection type food waste disposer. Background Art
[0002] The food waste disposer can widely process food waste including cooked food waste and raw food waste. Cooked food waste includes leftovers, leftover rice, vegetable leaves, etc. Raw food waste includes fruit peels, fish bones, vegetable stems, egg shells, tea residues, bones, shells, etc. The food waste disposer includes a sink connection component and a main body connected to the sink connection component. The sink connection component can be quickly connected to the sink drain, so that the food waste falls into the main body through the drain and the sink connection component. The main body is composed of an anti-corrosion grinding chamber, a stainless steel grinding hammer, a stainless steel grinding disc, etc. It uses a high-speed rotating permanent magnet motor to drive the turntable in the grinding chamber. Under the action of centrifugal force, the food waste collides with each other in a very short time (it only takes about 10 seconds for general household use to complete the disposer), and the food waste is ground into fine particles and discharged into the pipeline along the water flow.
[0003] Although food waste disposers can easily process food waste, it is difficult to process if the food waste is mixed with metal parts. In daily life, people usually flush food waste directly into the food waste disposer without checking the food waste. Therefore, once the food waste is accidentally mixed with metal parts, it will most likely enter the food waste disposer. When the turntable rotates at high speed, the metal parts may damage the internal parts of the main body and produce huge noise.
[0004] Although existing food waste disposers are equipped with stall protection and can automatically shut down when stuck by metal parts, this still cannot promptly and effectively detect whether metal parts have fallen into the food waste disposer and prevent the food waste disposer from working when there are metal parts inside, resulting in major usage defects. Summary of the invention
[0005] In view of the deficiencies existing in the above-mentioned technologies, the present application provides a metal detection type food waste disposer, which can promptly detect fallen metal parts.

[0010] A control system is electrically connected to the motor and the first metal detection sensor. When the first metal detection sensor detects the metal part, the control system controls the motor to stop working.
[0011] Furthermore, the metal detection assembly also includes a magnetic ring located above the first metal detection sensor, and the magnetic ring is used to absorb ferromagnetic metal parts passing through the channel.
[0012] Furthermore, the metal detection component also includes an upper connecting member connected to the sink connecting member and a lower connecting member connected to the shell, the lower connecting member and the upper connecting member are respectively provided with a first inner hole and a second inner hole, and the first inner hole and the second inner hole cooperate to form the channel.
[0013] Furthermore, the lower connecting member is provided with a first threaded hole for installing a first metal detection sensor, and the lower connecting member is also provided with a first spacer separating the first threaded hole and the first inner hole.
[0014] Furthermore, the lower connecting member is slidably fitted in the second inner hole of the upper connecting member, the sink connecting assembly is provided with a pipe portion extending to the bottom of the sink, and the metal detection assembly also includes a spring that drives the upper connecting member to press upward against the pipe portion.
[0015] Furthermore, a protruding step ring is provided on the inner wall of the first inner hole, and the magnetic ring is fitted in the first inner hole, with its bottom supported by the step ring.
[0016] Furthermore, the metal detection assembly also includes a pressure ring threadedly connected to the inner wall of the first inner hole, and the pressure ring cooperates with the step ring to clamp the two ends of the magnetic ring.

[0020] Compared with the prior art, the present application has the following beneficial effects:
[0021] 1. By setting a first metal detection sensor capable of detecting the passing of metal pieces, when a metal piece is detected, the first metal detection sensor can feed back a signal to the control system, and the control system controls the motor to stop working, thereby effectively preventing the food waste disposer from forcibly working in the presence of metal pieces, which is safer and more reliable;

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0029] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.
[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0031] like Figure 1 As shown, a metal detection type food waste disposer corresponding to a preferred embodiment of the present application includes a sink connection component 1, a main body 2, and a metal detection component 3 connected between the sink connection component 1 and the main body 2.
[0032] The sink connection assembly 1 is used to connect with the sink drain outlet, and includes a feed ring 10 installed in the sink drain outlet and a locking ring 11 located below the sink drain outlet. The feed ring 10 is inserted into the sink drain outlet and is locked and fixed by the locking ring 11. The feed ring 10 includes a pipe part 12 for objects such as kitchen waste to pass through. The lower end of the pipe part 12 extends to below the sink drain outlet and is connected to the metal detection assembly 3.
[0033] The main body 2 is used to crush kitchen waste and discharge the crushed kitchen waste. It includes a shell 20, a motor disposed in the shell 20, and a grinding assembly driven by the motor. The motor drives the grinding assembly to work to crush the kitchen waste. An annular connection port 21 is formed at the upper end of the shell 20 for connecting to the metal detection assembly 3.
[0034] refer to Figure 1 and Figure 2The metal detection assembly 3 includes an upper connection member 30 connected to the tube portion 12, a lower connection member 31 connected to the connection port 21, and a first metal detection sensor 32 connected to the lower connection member 31. The lower connection member 31 is annular and is provided with a first inner hole 310. There can be multiple first metal detection sensors 32, which are used to detect whether metal passes through the first inner hole 310. The first metal detection sensor 32 is threadedly connected to the first threaded hole 31a on the lower connection member 31, and is horizontally arranged and points to the center of the first inner hole 310. When the lower connection member 31 is in a circular tube shape, the first metal detection sensor 32 is radially arranged on the lower connection member 31.
[0035] The metal detection sensor can detect whether there is a metal piece passing through the first inner hole 310. When a metal piece passes through the first inner hole 310, it can generate an induction signal. Preferably, the metal detection sensor is a metal detection proximity switch. The first metal detection sensor 32 is electrically connected to the control system of the kitchen waste disposer. When a metal piece is detected passing through the first inner hole 310, it can transmit a signal to the control system. The control system can issue an alarm through sound and light to remind the user that a metal piece has fallen into the main body 2. When a metal piece falls into the kitchen waste disposer, the control system will control the motor to stop working. In this application, controlling the motor to stop working includes the following two situations: when the kitchen waste has not yet worked, the motor will not be able to be started to work; and when the kitchen waste disposer is running, the control system will control the motor to stop rotating. Only when the reset button is manually pressed, the motor of the kitchen waste disposer can work normally. In this way, the user can be prompted to remove the metal piece and better protect the kitchen waste disposer.
[0036] Preferably, the first metal detection sensor 32 is not directly exposed in the first inner hole 310, and the two are separated by the first spacer 36 to better protect the first metal detection sensor 32. In a preferred embodiment, the first threaded hole 31a is set as a blind hole, and the first spacer 36 is the material on the lower connecting member 31 that separates the first inner hole 310 and the first threaded hole 31a; in another preferred embodiment, the first threaded hole 31a is a through hole, and the first spacer 36 is an independent component that blocks the bottom of the first threaded hole 31a. Through the isolation effect of the first spacer 36, kitchen waste, water, oil and other objects will not contact the first metal detection sensor 32, effectively ensuring the reliability and service life of the metal detection sensor 32.
[0037] like Figure 2 As shown, a first conical surface 312 is provided at the upper end of the lower connecting member 31, so that the upper end of the lower connecting member 31 is in the shape of a trumpet with a larger upper portion and a smaller lower portion, which can guide the kitchen waste more smoothly into the first inner hole 310 and prevent the kitchen waste from accumulating at the upper end of the lower connecting member 31.
[0038] The bottom of the lower connecting member 31 is supported by the connecting port 21, and a plurality of positioning pins 22 are arranged on the connecting port 21. The lower connecting member 31 is provided with pin holes 313 that cooperate with the positioning pins 22, and is positioned by the positioning pins 22. A sealing ring 23 is also arranged between the lower connecting member 31 and the connecting port 21, and the elastic force of the spring 33 drives the lower connecting member 31 and the connecting port 21 to clamp the sealing ring 23.
[0039] In order to minimize the metal parts from falling into the main body 2, a magnetic ring 34 is provided on the inner wall of the lower connecting member 31. The magnetic ring 34 is made of an annular magnet. When the ferromagnetic metal parts pass through the magnetic ring 34, they will be adsorbed by the magnetic ring 34, thereby preventing them from falling into the main body 2, which is safer. In addition, since the magnetic ring 34 can reduce the ferromagnetic metal parts from falling into the main body 2, the magnetic ring 34 can reduce the frequency of the first metal detection sensor 32 detecting the metal parts, thereby reducing the number of alarms of the kitchen waste disposer, which is more convenient to use.
[0040] In order to facilitate the installation of the metal detection assembly 3 and to facilitate the removal of the metal parts adsorbed by the magnetic ring 34, a sliding matching method is adopted between the upper connecting member 30 and the lower connecting member 31, and a spring 33 is arranged between the upper connecting member 30 and the lower connecting member 31. Specifically, the upper connecting member 30 is provided with a second inner hole 300 matched with the outer surface of the lower connecting member 31, and the lower connecting member 31 can slide along the second inner hole 300. A convex step surface 311 is arranged at the lower part of the lower connecting member 31, and the spring 33 is sleeved on the lower connecting member 31, and the two ends are respectively against the bottom surface 301 and the step surface 311 of the upper connecting member 30. The spring 33 is in a compressed state and can drive the upper connecting member 30 to press against the pipe part 12 upward. A receiving groove 302 matched with the pipe part 12 is arranged at the upper end of the upper connecting member 30, and the pipe part 12 can be inserted into the receiving groove 302 and press against the upper connecting member 30, thereby improving the sealing between the two.
[0041] When the connecting piece 30 is pressed down, it will be separated from the tube 12, thereby freeing up space for a person's hand to reach in, making it easier to remove the adsorbed metal piece.
[0042] The installation method of the magnetic ring 34 and the lower connecting member 31 is not limited. For example, the two can be connected by gluing, or by a tight fit, or by using a method such as Figure 2The connection is as shown: an outwardly convex step ring 316 is provided on the inner wall of the lower connecting member 31, the outer surface of the magnetic ring 34 is matched with the first inner hole 310, the bottom is supported by the step ring 316, and a pressure ring 314 is provided on the upper end of the magnetic ring 34. The pressure ring 314 is threadedly connected to the inner wall of the lower connecting member 31, so that the magnetic ring 34 can be clamped and fixed between the pressure ring 314 and the step ring 316. A second conical surface 315 is provided on the upper end of the step ring 316 to facilitate the entry of kitchen waste. Preferably, the taper of the second conical surface 315 is the same as that of the first conical surface 312, and the two have a smooth transition. Further, the inner surface of the pressure ring 314, the inner surface of the magnetic ring 34 and the inner surface of the step ring 316 are flush.
[0043] In order to enable the user to better judge whether there is a metal piece adsorbed by the magnetic ring 34, the metal detection assembly 3 also includes a second metal detection sensor 35 disposed on the upper connecting member 30. The second metal detection sensor 35 is also used to detect whether there is metal passing through and is electrically connected to the control system. Since the second metal detection sensor 35 is above the magnetic ring 34, when the second metal detection sensor 35 detects that there is metal passing through, but the first metal detection sensor 32 fails to detect it, it indicates that the metal piece has been adsorbed by the magnetic ring 34. At this time, the control system can prompt the user to remove the metal piece.
[0044] Obviously, a second spacer 37 may be disposed between the second threaded hole 30a for mounting the second metal detection sensor 35 and the second inner hole 300 to protect the second metal detection sensor 35. The second spacer 37 has a similar structure to the first spacer 36 and will not be described in detail herein.
[0045] To ensure that the metal detection sensor works reliably, the first spacer 36 and the second spacer 37 are made of insulating material. More preferably, the upper connecting member 30 and the lower connecting member 31 are both made of insulating material.
[0046] In the present application, the first inner hole 310 and the second inner hole 300 together constitute a channel for kitchen waste to enter the main body 2. The kitchen waste in the sink can enter the channel through the feeding ring 10 and be detected by the metal detection sensor in the channel, wherein the ferromagnetic material will be adsorbed by the magnetic ring 34. Specifically, the kitchen waste will pass through the second metal detection sensor 35, the magnetic ring 34 and the first metal detection sensor 32 in sequence. When metal pieces are mixed in the kitchen waste and the metal pieces are detected by the first metal detection sensor 32, it indicates that the metal pieces have fallen into the main body 2. At this time, the control system controls the motor to stop working; when the first metal detection sensor 32 fails to detect the metal pieces, and the second metal detection sensor 35 detects the metal pieces, it indicates that the metal pieces are ferromagnetic metal pieces and have been adsorbed by the magnetic ring 34. At this time, the control system issues an alarm that the magnetic ring 34 adsorbs the metal pieces. The alarm can be realized by voice prompts or text displays, etc. In this case, the kitchen waste disposer can work normally.
[0047] The metal detection type kitchen waste disposer of the present application has at least the following advantages:
[0048] 1. By setting a first metal detection sensor capable of detecting the passing of metal pieces, when a metal piece is detected, the first metal detection sensor can feed back a signal to the control system, and the control system controls the motor to stop working, thereby effectively preventing the food waste disposer from forcibly working in the presence of metal pieces, which is safer and more reliable;
[0049] 2. By setting a magnetic ring at the upper end of the first metal detection sensor, some ferromagnetic metal parts can be adsorbed, which reduces the frequency of the kitchen waste disposer stopping working and is more convenient to use;
[0050] 3. By setting a second metal detection sensor located at the upper end of the magnetic ring, the control system can determine whether there are ferromagnetic metal parts adsorbed on the magnetic ring based on the feedback signals received from the first and second metal detection sensors, thereby reminding the user to clean the metal parts on the magnetic ring, which is more convenient.
[0051] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
