Description

Technical Field

[0001] The present application relates to a food waste disposer, and more particularly to an anti-clogging 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., and 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 grinding disc in the grinding chamber. The food waste collides with each other under the action of centrifugal force. In a very short time (general household use only takes about ten seconds to complete the disposer), the food waste is ground into fine particles and discharged into the pipeline along the water flow.

[0003] Food waste disposers use water as a medium to process leftover food. When the food waste particles are too large and too much, the pipes may be blocked due to insufficient carrying capacity. Although the existing technology is constantly improving the grinding fineness of food waste disposers, making the size of the crushed food waste smaller and smaller, due to installation errors or processing size problems, it is still difficult to ensure that the fineness of the ground particles can fully meet the requirements. In the case of different particle sizes, the pipes may still be blocked. Once the pipes are blocked, maintenance will be very troublesome and will affect normal life. Summary of the invention

[0004] In view of the deficiencies existing in the above-mentioned technologies, the present application provides an anti-clogging food waste disposer, which can better prevent the crushed food waste from clogging the pipe.

[0010] Furthermore, the bottom of the filter disc is provided with a plurality of outwardly protruding convex portions, the drive disc has corresponding bosses, and the convex portions and / or the bosses are provided with transition surfaces.

[0011] Furthermore, the filter assembly also includes a guide ring connected to the shell, and the disc body of the filter disc is slidably fitted in the guide ring along the vertical direction.

[0012] Furthermore, the guide ring is provided with a plurality of vertically arranged guide grooves, and the disc body is provided with a sliding fitting portion matched with the guide grooves.

[0013] Furthermore, a conical surface inclined toward the filter disc is provided at the upper end of the guide ring, and the conical surface is used to guide the kitchen waste to flow onto the filter disc.

[0014] Furthermore, the shell is provided with a discharge port, the shell further comprises a sealing cover connected to the discharge port, and the guide ring is provided with a guide hole corresponding to the discharge port.

[0015] Furthermore, one end of the spring abuts against the filter disc, and the other end abuts against the grinding assembly.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] like Figure 1 As shown, an anti-clogging food waste disposer corresponding to a preferred embodiment of the present application includes a main body 1 and a sink connecting component 2 connected to the upper end of the main body 1, and the sink connecting component 2 is used to be connected to the sink drain so that the food waste in the sink can be flushed into the main body 1 along with the water flow.

[0036] The main body 1 includes a housing 10 and a driving motor 3 , a grinding assembly 4 and a filtering assembly 5 installed in the housing 10 .

[0037] The housing 10 is usually assembled from a plurality of housings to facilitate installation of the drive motor 3, the grinding assembly 4 and the filter assembly 5 in the housing 10. A motor mounting frame 11 is provided in the housing 10, the drive motor 3 is mounted on the motor mounting frame 11, and the rotating shaft 30 of the drive motor 3 extends upward through the motor mounting frame 11 to drive the grinding assembly 4 and the filter assembly 5 to work. To ensure smooth operation of the motor rotating shaft 30, a first bearing 12 is further provided between the rotating shaft 30 and the motor mounting frame 11.

[0038] The main body 1 also includes a chassis 13 arranged inside the shell 10. The chassis 13 is used to guide the crushed kitchen waste to flow into the sewer along with the water. The shell 10 is provided with a connecting port 100 connected to the sewer. The chassis 13 is provided with a guide portion 130 inclined toward the bottom of the connecting port 100. The guide portion 130 can be in the form of a guide surface or a guide groove, so that the kitchen waste located on the chassis 13 can be gathered to the connecting port 100 under the action of gravity and finally flow into the sewer.

[0039] In the present application, the grinding component 4, the filtering component 5 and the bottom plate 13 are sequentially arranged from top to bottom in the outer shell 10. For the convenience of description, the area above the grinding component 4 is called the grinding area 60, the area between the grinding component 4 and the filtering component 5 is called the filtering area 61, and the area between the filtering component 5 and the bottom plate 13 is called the discharge area 62.

[0040] The grinding assembly 4 is used to crush the kitchen waste, and the crushed kitchen waste will be discharged into the filtering area 61. The grinding assembly 4 includes a grinding ring 40 fixed in the housing 10 and a grinding disc 41 arranged in the grinding ring 40. The grinding disc 41 is connected to the rotating shaft 30 of the driving motor 3 and is driven to rotate by the driving motor 3. The peripheral wall of the grinding ring 40 is provided with a plurality of holes or grooves, and the grinding disc 41 is provided with a grinding hammer 42 and a tearing device and other components. The tearing device is used to tear the kitchen waste and stir the water flow to make the kitchen waste be thrown to the peripheral wall of the grinding ring 40. The kitchen waste on the peripheral wall is ground into fine particles by the cooperation of the grinding hammer 42 and the grinding ring 40, and flows into the filtering area 61.

[0041] The filter assembly 5 is used to filter the crushed kitchen waste according to its size, and only the small-sized kitchen waste that meets the requirements can flow into the discharge area 62 for discharge, thereby reducing the risk of blockage of the sewer pipe. The filter assembly 5 includes a drive disc 50, a filter disc 51 and a spring 52.

[0042] like Figure 2 As shown, the filter plate 51 is used to filter kitchen waste, and includes a plate body 511 with a plurality of filter holes 510. The size of the filter holes 510 can be designed according to the situation, so as not to block the sewer pipe, and is preferably consistent with the design size of the kitchen waste particles after the kitchen waste disposer grinds them. In this application, kitchen waste that can pass through the filter holes 510 is called small-particle kitchen waste, which basically does not block the sewer pipe, and kitchen waste that cannot pass through the filter holes 510 is called large-particle kitchen waste, which has the risk of blocking the sewer pipe.

[0043] like Figure 3As shown, a plurality of protrusions 512 are provided on the bottom surface of the disk body 511 , and the plurality of protrusions 512 are evenly distributed on the disk body 511 with the center of the filter disk 51 as the center. The protrusions 512 are provided with a first transition surface 513 , and the first transition surface 513 is an inclined surface or an arc surface, and extends to the disk body 511 .

[0044] like Figure 1 , Figure 4 and Figure 5 As shown, the filter assembly 5 also includes a guide ring 54 connected to the inner wall of the housing 10, and the filter disc 51 and the guide ring 54 are slidably matched. Specifically, the outer peripheral surface of the disc body 511 of the filter disc 51 is matched with the inner hole of the guide ring 54, so that the kitchen waste will not pass through the gap between the disc body 511 and the guide ring 54, or the gap between the disc body 511 and the guide ring 54 is less than or equal to the size of small-particle kitchen waste. A plurality of outwardly convex sliding parts 514 are arranged on the outer peripheral surface of the disc body 511, and a guide groove 540 matched with the sliding part 514 is opened on the guide ring 54. The guide groove 540 is vertically arranged. Through the cooperation between the sliding part 514 and the guide groove 540, the filter disc 51 can only move in the up and down direction, and cannot rotate.

[0045] Preferably, an inclined conical surface 541 is provided at the upper end of the guide ring 54 , so that the guide ring 54 is in a trumpet shape that is larger at the top and smaller at the bottom, which can better guide the kitchen waste to gather on the filter plate 51 .

[0046] The driving disc 50 is used to drive the filter disc 51 to vibrate up and down, and is connected to the rotating shaft 30 and can be driven to rotate by the rotating shaft 30. Figure 6 and Figure 7 As shown, the upper surface of the driving disk 50 is provided with an outwardly protruding boss 500, and the position of the boss 500 corresponds to the position of the convex portion 512, and can intermittently contact the convex portion 512 during the rotation of the driving disk 50, so that the filter disk 51 continuously vibrates up and down. Specifically, when the boss 500 contacts the convex portion 512, the height of the filter disk 51 is relatively high, and when the boss 500 gradually separates from the convex portion 512, the height of the filter disk 51 will gradually decrease, and as the boss 500 continues to move to the convex portion 512, the height of the filter disk 51 will rise again, and in this cycle, the filter disk 50 will continuously vibrate up and down. The boss 500 is also provided with a second transition surface 501, and the second transition surface 501 is an inclined surface or a curved surface, which can make the vibration smoother and prevent collision.

[0047] Preferably, the number of bosses 500 is at least two and they are evenly distributed around the center of the driving disk 50, so that the force on the filter disk 51 is more symmetrical and uniform, preventing the filter disk 51 from tilting due to unilateral force.

[0048] The spring 52 is used to apply a downward thrust to the filter disc 51 so that the filter disc 51 and the drive disc 50 can reliably abut against each other, thereby ensuring that the drive disc 50 can drive the filter disc 51 to vibrate reliably.

[0049] In a preferred embodiment, two ends of the spring 52 respectively abut against the filter disc 51 and the grinding disc 41 , thereby applying a downward thrust to the filter disc 51 .

[0050] Since the grinding disc 41 will rotate at a high speed, the spring 52 directly abuts against the grinding disc 41, which may easily damage the spring 52 and reduce its service life. Therefore, in another preferred embodiment, as shown in FIG. Figure 1 and Figure 8 As shown, the filter assembly 5 also includes a gland 53 and a second bearing 55 connected between the gland 53 and the grinding disc 41. A mounting ring 530 is provided at the upper end of the gland 53, and a mounting hole 410 is provided on the grinding disc 41. The second bearing 55 is installed in the mounting ring 530 and the mounting hole 410, and is matched with the rotating shaft 30. The rotating shaft 30 is penetrated in the gland 53 and will not drive the gland 53 to rotate when rotating. Preferably, the second bearing 55 is a thrust bearing or a plane bearing. The two ends of the spring 52 are respectively against the gland 53 and the filter disc 51. Due to the presence of the second bearing 55, the rotation of the grinding disc 41 will not be transmitted to the gland 53, and no torsion will be applied to the spring 52, which is beneficial to protecting the spring 52 and improving its service life.

[0051] Furthermore, an annular sealing portion 413 matched with the mounting ring 530 is provided on the grinding disc 41, and the outer periphery of the mounting ring 530 is matched with the inner hole of the sealing portion 413, and a sealing ring 411 is provided between the mounting ring 530 and the sealing portion 413, so that food waste, water and other debris will not contact the second bearing 55, which is conducive to the reliable operation of the second bearing 55.

[0052] Furthermore, if Figure 2 and Fig. 9 As shown, the body 511 of the filter disc 51 is provided with an upwardly extending mounting portion 516, the mounting portion 516 is provided with an annular mounting groove 517, and the spring 52 is installed in the mounting groove 517. As a preferred embodiment, the pressure cover 53 is covered on the mounting portion 516, which includes a pressing plate 533 and a cover ring 531 connected to the pressing plate 533, the cover ring 531 is sleeved on the outside of the mounting portion 516, and a sealing ring can also be arranged between the two, so that kitchen waste and water and other debris will not enter the mounting portion 516 to affect the work of the spring 52. A plurality of vertically arranged slide grooves 532 are also arranged on the inner wall of the cover ring 531, and the mounting portion 516 is provided with a plurality of externally protruding guide blocks 518, which are matched with the slide grooves 532, can further prevent the pressure cover 53 from rotating, and at the same time do not affect the up and down vibration of the filter disc 51.

[0053] like Figure 1 As shown, a discharge port 101 is provided at a position corresponding to the filter area 61 on the housing 10, and the discharge port 101 is used to discharge large particles of kitchen waste on the filter plate 51. Figure 4 and Figure 5 As shown, a guide hole 542 is provided at a position corresponding to the discharge port 101 on the guide ring 54, and a bottom surface 543 of the guide hole 542 is inclined downward to discharge the kitchen waste more smoothly from the discharge port 101. A sealing cover 102 is detachably connected to the discharge port 101, and the sealing cover 102 can be threadedly connected to the discharge port 101 or connected to the housing 10 by bolts. When large particles of waste need to be discharged, the sealing cover 102 is opened, and then the drive motor 3 can be turned on. The drive motor 3 will drive the filter plate 51 to vibrate, so that the large particles of kitchen waste move toward the discharge port 101 during the vibration process, and finally discharge the discharge port 101.

[0054] Furthermore, a transparent observation window 103 is provided at a position corresponding to the filter area on the housing 10, through which the accumulation of kitchen waste on the filter plate 51 can be observed. When a lot of kitchen waste is accumulated, the sealing cover 102 can be opened for cleaning.

[0055] When the anti-clogging kitchen waste disposer of the present application is working, the driving motor 3 will simultaneously drive the grinding disc 41 and the driving disc 30 to rotate, that is, the grinding assembly 4 and the filtering assembly 5 will work at the same time, and the kitchen waste entering the main body 1 will first be crushed and ground at the grinding assembly 4, and then enter the filtering assembly 5, and the small particles of kitchen waste can be discharged to the sewer pipe through the connecting port 100 after passing through the filter disc 31, and the large particles of kitchen waste are left on the filter disc 31. Since the filter disc 31 is constantly vibrating during the filtering process, the filtering is more sufficient and rapid. Preferably, the kitchen waste disposer continues to work for a period of time after the water valve stops inletting water, so that the filter disc 31 can be vibrated and filtered in the absence of water or less water, and the filtering effect is better. When there is a lot of kitchen waste piled up on the filter disc 31, the sealing cover 102 can be opened, and the driving motor 3 can be started, so that the large particles of kitchen waste can be discharged from the sealing cover 102 under the driving of the vibration force, which is very convenient.

[0056] The anti-clogging kitchen waste disposer of the present application has at least the following advantages:

[0057] 1. The anti-clogging food waste disposer of the present application is provided with a filter plate in the housing, which can allow small particles of food waste to pass through and intercept large particles of food waste, so that only small particles of food waste can enter the sewer pipe, effectively reducing the risk of clogging of the sewer pipe and making it more reliable to use;

[0058] 2. The anti-clogging kitchen waste disposer of the present application is also provided with a driving disc driven to rotate by a driving motor shaft and a spring driving the filter disc to press against the driving disc. The boss on the driving disc cooperates with the convex part on the filter disc, and can drive the filter disc to vibrate up and down during the rotation of the driving disc, thereby accelerating the filtering speed and making the filtering more complete.

[0059] 3. The anti-clogging food waste disposer of the present application is also provided with a discharge port corresponding to the filter plate and a sealing cover arranged in the discharge port. When the sealing cover is removed, the food waste accumulated on the filter plate can be discharged through the discharge port, which is more convenient.

[0060] 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.
