Description

Technical Field

[0001] The utility model belongs to the technical field of garbage disposal, and in particular relates to a kitchen waste disposer. Background Art

[0002] Existing food waste disposers generally include a casing with a feed port and a discharge port, a crushing element arranged in the casing, and a driving mechanism for driving the crushing element to work. The crushing element can crush the food waste entering from the feed port under the drive mechanism.

[0003] Specifically, the Chinese utility model patent "A Kitchen Waste Disposer" with patent number 202221965311.8 and authorization announcement number CN218292145U includes a casing and a grinding cover, a grinding disc is installed inside the grinding cover, and the grinding cover includes an upper grinding cover and a lower grinding cover. The upper grinding cover is provided with a feeding port on the top, and the lower grinding cover is provided with a discharge port. An annular wall is installed on the inner peripheral wall of the lower side of the upper grinding cover, and the annular wall is provided above the grinding disc. An annular cavity is formed between the annular wall and the upper grinding cover. A water inlet connected to the annular cavity is provided on the outer peripheral wall of the upper grinding cover, and a water outlet is provided on the inner wall of the annular cavity. An annular cutter that can rotate under the action of water pressure is installed in the annular cavity.

[0004] Another example is the Chinese utility model patent "A Kitchen Waste Treatment System" with patent number 202321652436.X and authorization announcement number CN220538788U, which includes a water sink and a garbage disposer arranged under the water sink. The garbage disposer includes a grinding chamber and a grinding disc arranged in the grinding chamber. The grinding chamber has a discharge port, which is arranged below the grinding disc. It is characterized in that a step structure is formed at the bottom of the water sink, a main feeding port is opened at the top of the step structure, a feeding cover is installed on the main feeding port, and the top of the grinding chamber is installed on the main feeding port.

[0005] In addition to considering the crushing effect, the design of existing food waste disposers also needs to consider the user experience and safety. In order to prevent garbage from splashing out from the feed port during disposal, a cover such as a feeding cover or a splash-proof cover is generally set at the feed port. When feeding, the cover is opened to expose the feed port. After feeding, the cover is closed for garbage disposal. However, when the cover is closed, the food waste disposer is working, and the crushed food waste is quickly discharged from the drainage pipe, negative pressure will be generated in the crushing chamber inside the casing. Negative pressure will affect the rapid discharge of the crushed food waste. At the same time, when the cover needs to be opened, the negative pressure will cause the cover to be unable to open normally. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a kitchen waste disposer capable of balancing air pressure in response to the current status of the existing technology.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a kitchen waste disposer, comprising:

[0008] A housing having a crushing chamber therein, wherein the upper portion of the crushing chamber has a feed port, and the lower portion of the crushing chamber has a discharge port;

[0009] A crushing element is disposed in the crushing chamber and can work under the drive of the driving mechanism to crush the kitchen waste entering from the feed port;

[0010] It is characterized by also including:

[0011] An air intake pipe, a first end of which is connected to the outside world, and a second end of which is open to the cavity wall of the pulverizing chamber, and a pressure balance block is provided in the air intake pipe, the pressure balance block divides the internal space of the air intake pipe into a first channel connected to the pulverizing chamber and a second channel connected to the outside world, and the pressure balance block is arranged to be able to move along the length direction of the air intake pipe under the action of the air pressure difference in the first channel and the second channel.

[0012] The pressure balancing block in the utility model can move along the length direction of the air inlet pipe under the action of the air pressure difference between the first channel and the second channel, thereby balancing the air pressure outside and the air pressure in the pulverizing chamber.

[0013] Preferably, along the direction of air flow from the first end to the second end of the intake duct, at least a portion of the intake duct is inclined upward to allow the pressure balance weight to be movably disposed therein. The pressure balance weight is constantly inclined downward under its own weight. Furthermore, when the air pressure within the first channel is lower than the air pressure within the second channel, the pressure balance weight is configured to move upward, overcoming its own weight. In this manner, under normal conditions, the pressure balance weight can move downward under its own weight and return to its original position. When negative pressure is generated within the pulverizing chamber, the pressure balance weight can move upward, overcoming its own weight, to balance the air pressure inside and outside the pulverizing chamber.

[0014] Preferably, the air intake pipe has a first air intake section and a second air intake section arranged and connected along the length direction, the port of the first air intake section is the first end of the air intake pipe, the port of the second air intake section is the second end of the air intake pipe, the flow area on the cross section of the first air intake section is larger than the flow area on the cross section of the second air intake section, and the pressure balance block can be movably arranged in the first air intake section.

[0015] Preferably, a step is formed at the junction of the first air intake section and the second air intake section, and a limit block protruding toward the first air intake section is provided on the step surface to limit the pressure balance block from moving further toward the second air intake section.

[0016] In order to further balance the air pressure inside and outside the pulverizing chamber, preferably, the pressure balancing block is provided with a through hole connecting the first channel and the second channel, and is provided with a valve body for opening and closing the through hole.

[0017] Preferably, the valve body is a normally closed valve body. When the pressure balance block is relatively close to the second air inlet section and relatively far away from the port of the first air inlet section, and the air pressure in the first channel is lower than the air pressure in the second channel, the valve body moves under the action of the air pressure difference between the first channel and the second channel to open the through hole.

[0018] In this way, when the air pressure in the crushing chamber decreases, the pressure balance block moves upward and stops when it moves close to the second air inlet section. If the air pressure in the crushing chamber continues to decrease, the normally closed valve body opens under the action of the air pressure difference between the first and second channels, and the air in the second channel enters the first channel and the crushing chamber through the through hole.

[0019] Furthermore, the valve body is a one-way valve disc, the upper side of which is rotatably connected to the through hole, and the lower side of which blocks the through hole under the action of the one-way valve disc's own elastic force or gravity. When the pressure balance block is relatively close to the second air intake section and relatively far away from the port of the first air intake section, and the air pressure in the first channel is lower than the air pressure in the second channel, the lower side of the one-way valve disc rotates toward the first channel under the action of the air pressure difference between the first channel and the second channel to open the through hole.

[0020] Furthermore, the cross section of the air intake duct is circular, and correspondingly, the pressure balance block is cylindrical, and the side wall of the cylinder is in contact with the inner wall surface of the air intake duct.

[0021] In each of the above schemes, preferably, a water inlet pipe is further included, the water inlet end of which is connected to an external water source, and the water outlet end of which is connected to the grinding chamber.

[0022] Preferably, the device also includes a cover, located at the feed opening of the pulverizing chamber to open and close the feed opening. This cover improves the safety of the food waste disposer during operation by preventing food waste from splashing upward. Furthermore, the design of the air intake duct with a pressure balance block in this utility model prevents the cover from being sucked in by the negative pressure within the pulverizing chamber and becoming unable to open.

[0023] Compared with the prior art, the advantages of the present invention are that the pressure balancing block can move along the length of the air intake pipe under the action of the pressure difference between the first channel and the second channel, thereby balancing the air pressure outside and inside the crushing chamber.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 6 As shown, a preferred embodiment of a food waste disposer of the present invention is shown, which includes an organic shell 1, a crushing part 2, an air intake pipe 4, a pressure balance block 5, a valve body 6, a water inlet pipe 7 and a cover body 8.

[0032] The housing 1 includes an outer shell 11 and an inner liner 12 disposed within the outer shell 11. The inner liner 12 is hollow and defines a crushing chamber 10. A feed port 10a is provided at the top of the crushing chamber 10, and a discharge port 10b is provided on the lower sidewall of the crushing chamber 10. A valve is provided at the discharge port 10b to open and close the discharge port 10b. A hollow hole is provided on the bottom wall of the outer shell 11.

[0033] like Figure 2 As shown, the pulverizing element 2 is a conventional grinding disc, equipped with a mating grinding ring 21. The grinding ring 21 is circumferentially positioned within the pulverizing chamber 10, below the feed inlet 10a and above the discharge outlet 10b. The grinding disc is located within the inner periphery of the grinding ring 21 and, driven by a drive mechanism 3 (a motor), is able to rotate circumferentially relative to the grinding ring 21 to pulverize food waste entering through the feed inlet 10a. The principle of the grinding disc and grinding ring 21 cooperating to pulverize waste in this embodiment is similar to that of the prior art and will not be elaborated here.

[0034] The cover 8 is disposed at the feed opening 10a of the grinding chamber 10 to close the feed opening 10a. In this embodiment, the cover 8 can adopt an existing cover structure, which will not be described in detail here, and the cover 8 can be separated from the feed opening 10a upward under the action of an external force to open the feed opening 10a.

[0035] The above-mentioned air intake pipe 4 is arranged inside the outer shell 11 and outside the inner tank 12, and the first end of the air intake pipe 4 is connected to the outside through the hollow hole on the outer shell 11, and the second end of the air intake pipe 4 is open to the cavity wall of the crushing chamber 10, and a pressure balance block 5 is provided in the air intake pipe 4. The pressure balance block 5 divides the internal space of the air intake pipe 4 into a first channel 41 connected to the crushing chamber 10 and a second channel 42 connected to the outside, and the pressure balance block 5 is arranged to be able to move along the length direction of the air intake pipe 4 under the action of the air pressure difference between the first channel 41 and the second channel 42.

[0036] Specifically, the cross section of the air intake duct 4 is circular, and the air intake duct 4 has a first air intake section 401 and a second air intake section 402 arranged and connected along the length direction. The port of the first air intake section 401 is the first end of the air intake duct 4, and the port of the second air intake section 402 is the second end of the air intake duct 4. The flow area on the cross section of the first air intake section 401 is greater than the flow area on the cross section of the second air intake section 402, and a step 403 is formed at the junction of the first air intake section 401 and the second air intake section 402, and a limit block 404 protruding toward the first air intake section 401 is provided on the step surface. The pressure balance block 5 is arranged in the first air intake section 401 so as to be movable back and forth, and the pressure balance block 5 is cylindrical, and the side circumferential wall of the cylinder is in contact with the inner wall surface of the first air intake section 401. In addition, as Figure 5 、 6 As shown, along the direction of air flowing from the first end to the second end of the intake duct 4, the first intake section 401 of the intake duct 4 is inclined upward so that the pressure balance block 5 always has a tendency to move downward under the action of its own gravity. At the same time, when the air pressure in the first channel 41 is lower than the air pressure in the second channel 42, the pressure balance block 5 is arranged to overcome its own gravity and move upward until it stops moving under the obstruction of the limit block 404.

[0037] At the same time, if Figure 4 、 6As shown, in this embodiment, the pressure balance block 5 is provided with an axially extending through-hole 50 for connecting the first channel 41 and the second channel 42. A valve body 6 is provided on the pressure balance block 5 for opening and closing the through-hole 50. The valve body 6 is a normally closed valve. When the pressure balance block 5 is relatively close to the second air inlet section 402 and relatively far from the port of the first air inlet section 401, and the air pressure in the first channel 41 is lower than the air pressure in the second channel 42, the valve body 6 moves under the action of the air pressure difference between the first channel 41 and the second channel 42 to open the through-hole 50. Specifically, the valve body 6 is a one-way valve disc, the upper side of which is rotatably connected to the through hole 50, and the lower side of which blocks the through hole 50 under the action of the one-way valve disc's own elastic force or gravity. When the pressure balance block 5 is relatively close to the second air intake section 402 and relatively far away from the port of the first air intake section 401, and the air pressure in the first channel 41 is lower than the air pressure in the second channel 42, the lower side of the one-way valve disc rotates toward the first channel 41 under the action of the air pressure difference between the first channel 41 and the second channel 42 to open the through hole 50.

[0038] In this way, when the air pressure in the pulverizing chamber 10 decreases, the pressure balance block 5 moves upward in the first air inlet section 401 until it is blocked by the limit block 404 and stops moving upward. At this time, if the air pressure in the pulverizing chamber 10 continues to decrease, the normally closed valve body opens under the action of the air pressure difference between the first and second channels, and the air in the second channel 42 enters the first channel 41 and the pulverizing chamber 10 through the through hole 50, thereby balancing the air pressure inside and outside the pulverizing chamber.

[0039] The water inlet end of the water inlet pipe 7 is connected to the external water source, and the water outlet end is connected to the grinding chamber 10. In this embodiment, the water outlet end of the water inlet pipe 7 is the second end of the air inlet pipe 4 opening to the wall of the grinding chamber 10.

[0040] In the specification and claims of this utility model, directional terms such as "upper," "lower," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the utility model. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these directional terms are intended for illustration only and should not be construed as limiting. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
