Description

Technical Field

[0001] The present application relates to the field of household cleaning devices, and in particular to kitchen cleaning devices, such as dishwashers. Background Art

[0002] In the prior art, the dishwasher dries the dishes in the washing tank by blowing air after stopping the water circulation. During the drying process, since the filter cartridge in the water collection cup is always connected to the washing tank, the residue in the filter cartridge will emit odor and pollute the cleaned dishes, making the dishes also have odor, causing a bad experience for users. Summary of the invention

[0003] The purpose of the present application is to overcome the above-mentioned defects or problems existing in the background technology and to provide a sprayer with an anti-odor cover and a cleaning device with an anti-odor function, which can prevent the residue in the filter cartridge from emitting odor during the subsequent drying or placement process after drying from contaminating the clean dishes.

[0004] In order to achieve the above purpose, the following technical solutions are adopted:

[0005] A shower with an anti-odor cover comprises: a shower arm which rotates under the reaction force of the water flow when spraying water; a water pipe which supplies water to the shower arm and whose top is connected to the shower arm in a limiting manner along the axial direction; a first protrusion facing inward or outward is provided at its bottom; and an anti-odor cover which is arranged on the outer wall of the water pipe or below the shower arm.

[0006] Furthermore, the deodorizing cover is also provided with a water passing portion, and the water passing portion penetrates the deodorizing cover along the axial direction of the water passing pipe.

[0007] Furthermore, a one-way valve is provided in the water flow portion, and the one-way valve only allows water to pass from one end of the water flow portion close to the spray arm to the other end.

[0008] Furthermore, the water pipe is fixedly connected to the spray arm.

[0009] Furthermore, the water pipe is rotatably connected to the spray arm.

[0010] A cleaning device with an odor-proof function, comprising: a cleaning tank, a water collecting port is provided at the bottom of the cleaning tank; a water collecting cup is fixedly connected to the cleaning tank and communicated with the cleaning tank through the water collecting port; a water supply pipe is provided with a water outlet end facing the water collecting port; and a filter cartridge is placed in the water collecting cup; it also includes the above-mentioned sprayer with an odor-proof cover; the water pipe is slidably connected to the water supply pipe along the axial direction, and the water outlet end of the water supply pipe is provided with a second protrusion facing outward or inward to form an axial limiting structure with the first protrusion to prevent the water pipe from being separated from the water supply pipe due to water pressure impact; the water pipe also passes through the filter cartridge and extends into the cleaning tank through the water collecting port; the odor-proof cover is located in the cleaning tank and shields the water collecting port when the water pipe drops to the lowest point along its axis.

[0011] Furthermore, the water pipe is fixedly connected to the spray arm and is rotatably connected to the water supply pipe.

[0012] Furthermore, the water pipe is rotatably connected to the spray arm and is non-rotatably connected to the water supply pipe.

[0013] Compared with the prior art, the above solution has the following beneficial effects:

[0014] The technical solution of the present application is to design a water pipe to rise up due to the water pressure during the cleaning process, and to slide down relative to the water supply pipe due to the loss of water pressure after the cleaning is completed, and to provide an odor-proof cover on the water pipe wall or under the spray arm, so that the odor-proof cover moves up during the cleaning process, and the cleaning trough is connected with the water collecting cup and the filter cartridge; and after the water supply is stopped, the odor-proof cover moves down to shield the water collecting port, and the cleaning trough is no longer connected with the water collecting cup and the filter cartridge over a large area, thereby achieving an odor-proof effect.

[0015] A one-way valve is provided in the water flow section to allow water to enter the water collecting cup through the water flow section on the odor-proof cover during the water intake process of the cleaning tank, while preventing gas from entering the cleaning tank from the water collecting cup and the filter cartridge.

[0016] No matter the water pipe is fixedly connected to the spray arm or rotatably connected to the water supply pipe, as long as the water pipe is connected to the spray arm along the axial limit connection, the spray arm can drive the water pipe to rise when the water circulates, ensuring that the spray arm can rotate smoothly during the cleaning process.

[0038] Embodiment 1

[0039] See also Figure 1 , Figure 1 The sprayer 4 with the anti-odor cover in the first embodiment is shown (for the sake of simplicity, hereinafter referred to as the sprayer 4). Figure 1As shown, the sprayer 4 in the first embodiment includes a spray arm 41, a water pipe 42 and an anti-odor cover 43. The spray arm 41 is composed of two arms extending in opposite directions. The upper surface of each arm has a plurality of nozzles 411. At least part of the nozzles 411 have a projection of their spray direction on the horizontal plane and a line connecting the nozzle 411 to the rotation axis of the spray arm 41, so that the spray arm 41 rotates around the rotation axis of the spray arm 41 under the action of the spray reaction force when spraying water. A spray channel connecting each nozzle 411 is formed in the spray arm 41. In this embodiment, the water pipe 42 is connected to the spray arm 41 as a whole, and is located below the spray arm 41 and is vertically arranged, and its axis coincides with the rotation axis of the spray arm 41. The water pipe 42 has a water channel extending in the vertical direction, and the water channel and the spray channel are connected to each other, so that the water pipe 42 can supply water to the spray arm 41. The bottom outer wall of the water pipe 42 is also provided with a first protrusion 421 protruding outward; the first protrusion 421 is in the shape of a boss in this embodiment. The outer wall of the first protrusion 421 is provided with a first sealing ring groove 422 for installing a sealing ring. In this embodiment, an odor-proof cover 43 is also provided below the spray arm 41 and around the outer wall of the water pipe 42. The odor-proof cover 43 is also provided with a water flow portion 431. A one-way valve 432 is provided in the water flow portion 431. The specific shape of the one-way valve 432 is as follows: Figure 2 The one-way valve shown is a duckbill one-way valve commonly used in the art, with a larger opening at the top and a smaller opening at the bottom, so that water can flow from one end of the water-passing portion 431 close to the spray arm 41 to the other end in one direction. The one-way valve 431 is made of silicone.

[0040] See also Figure 3 and Figure 4 , Figure 3 and Figure 4 The cleaning device 10 with deodorizing function in the first embodiment is shown, which comprises a cleaning tank 1, a water collecting cup 2, a filter cartridge 3, a sprayer 4 as described above, a circulation pump and a sealing ring.

[0041] Wherein the cleaning tank 1 is as Figure 4As shown, in this embodiment, the cleaning tank 1 is a tank where a sink-type dishwasher is located. Of course, the cleaning tank 1 is not limited to the sink of a sink-type dishwasher, and can also be any object that contains objects to be cleaned and performs cleaning operations on the objects to be cleaned. The cleaning tank 1 in this embodiment is characterized in that a top cover is also provided on the top of the cleaning tank 1, and the top cover is hingedly connected to the cleaning tank 1 and can rotate between an open position and a closed position. When the top cover is in the closed position, the top cover and the cleaning tank 1 are enclosed together to form a cleaning cavity. The cleaning cavity can accommodate objects to be cleaned. Generally, for easy access, as in the prior art, the objects to be cleaned (such as dishes) can be placed in a bowl basket first and then placed in the cleaning cavity. The bowl basket is provided with legs, which support the bottom of the bowl basket and form a certain space between the bottom lower surface of the bowl basket and the upper surface of the bottom of the cleaning tank 1. In this embodiment, the cleaning tank 1 is also provided with a water inlet (not shown in the figure) for directly or indirectly introducing cleaning water from the municipal water inlet pipeline. The bottom of the cleaning tank 1 is provided with a water collection port 11 as in the prior art. In this embodiment, the water collection port 11 is located at the center of the bottom of the cleaning tank 1, and the upper surface of the bottom of the cleaning tank 1 is configured to have a certain inclination angle (the inclination angle is not shown in the figure), so that residue and water are more easily concentrated to the water collection port 11.

[0042] Water collection cup 2 Figure 3 and Figure 4 As shown. In this embodiment, the water collection cup 2 is roughly cup-shaped, and its bottom is inclined. An outer flange is provided at its mouth, which is conducive to fixing the water collection cup 2 to the lower surface of the bottom of the cleaning tank 1. Figure 1 and Figure 2 As shown, when the water collection cup 2 is fixed to the cleaning tank 1, the cup mouth of the water collection cup 2 is sealed and aligned with the water collection port 11 of the cleaning tank 1, so that the water collection cup 2 is connected to the cleaning tank 1 through the water collection port 11 to collect the liquid in the cleaning tank 1 and send it to the circulation pump during the water circulation process, or discharge it to the drainage pipeline after the water circulation is completed. Figure 3 and Figure 4As shown, the inner cavity of the cup body of the water collecting cup 2 forms a water collecting cavity 21. A drain pipe 22 is also provided at the bottom of the inclined cup bottom of the water collecting cup 2, which is obliquely extended downward, and the drain pipe 22 is connected to the water collecting cavity 21. The drain pipe 22 is used to discharge the water in the water collecting cavity 21. In this embodiment, it connects two branches, wherein the first branch is connected to the water inlet end of the circulation pump, and the second branch is connected to the drainage pipeline through a drainage valve. During each water circulation process, the drain pipe 22 is connected to the first branch to supply water to the circulation pump; at the end of each water circulation, the drain pipe 22 is connected to the second branch to discharge water from the water collecting cavity 21 to the drainage pipeline through the drainage valve. In this embodiment, the inner surface of the cup wall of the water collecting cup 2 is provided with a convex rib 23 perpendicular to the axis of the water collecting cup, and the convex rib 23 is used to support the filter cartridge 3 so that the filter cartridge 3 cannot move downward. The water collecting cup 2 is also provided with a water supply pipe 24. The water supply pipe 24 is located in the center of the cup bottom of the water collecting cup 2. The water inlet end of the water supply pipe 24 extends downward from the lower surface of the bottom of the water collecting cup 2 and is connected to the water outlet end of the circulation pump; the water outlet end of the water supply pipe 24 extends upward from the upper surface of the bottom of the water collecting cup 2, extends into the water collecting cavity 21 of the water collecting cup 2, and faces the water collecting port 11. The water supply seat tube is provided with a water supply channel. The water supply channel is a through hole that passes through the water supply pipe 24 in a vertical direction. The lower end of the water supply channel opens to the water inlet end of the water supply pipe 24, and the upper end opens to the water outlet end of the water supply pipe 24. At the water outlet end of the water supply pipe 24, the inner wall of the water supply pipe 24 is also provided with a second protrusion 241 that extends into the water supply channel. There are at least two second protrusions 241, and four in this embodiment.

[0043] Filter cartridge 3 Figure 3 and Figure 4 As shown. In this embodiment, the filter cylinder 3 includes a slag receiving part, a cylinder wall and a cylinder bottom which are connected to each other. Among them, the cylinder wall is located in the middle of the filter cylinder 3, which is a circular ring-shaped object with a certain height, and a plurality of filter holes are provided on the cylinder wall. The slag receiving part has an upper section and a lower section, wherein the upper section is also a circular ring-shaped object with a certain height, and the diameter is greater than the diameter of the cylinder wall, and the lower section is an inverted cone tubular object, wherein the upper end of the lower section is connected with the upper section, and the lower end of the lower section is connected with the cylinder wall; the wall thickness of the slag receiving part is equal to the wall thickness of the cylinder wall, and a plurality of filter holes are also provided on the wall. The cylinder bottom is connected with the lower end of the cylinder wall, and has two parts, an outer part and an inner part, wherein the outer part extends out of the cylinder wall, is in a circular ring shape and is arranged horizontally, and the outer diameter of the outer part of the cylinder bottom is equal to the outer diameter of the slag receiving part. The inner part is located inside the cylinder wall, is in a cone tube shape, and has a through hole. The wall thickness of the cylinder bottom wall is equal to the wall thickness of the cylinder wall, and a plurality of filter holes are also provided on the wall. In this embodiment, after installation, the filter cartridge 3 is against the rib 23 of the water collection cup 2, and is supported by the rib 23 so that it cannot move downward. Of course, even if the filter cartridge 3 is supported by the rib 23, the uppermost edge of the residue-bearing portion of the filter cartridge 3 is not higher than the water collection port 11, so that water and residue can be collected conveniently. In this example, the diameter of the through hole at the bottom of the cartridge is slightly larger than the diameter of the first protrusion 421 on the water pipe 42, so that the filter cartridge 3 can slide on the water pipe 42 without hindrance.

[0044] After the cleaning device 10 with deodorizing function in this embodiment is connected, the first protrusion 421 at the bottom of the water pipe 42 is located in the water supply channel of the water supply pipe 24, so that the water pipe 42 and the water supply pipe 24 are rotatably connected and slidably connected, and the sealing ring is located in the first sealing ring groove 422 and presses against the wall of the water supply channel to form a seal. After the first protrusion 421 is connected, it is also located below the second protrusion 241, so that the first protrusion 421 and the second protrusion 241 form an axial limiting structure to prevent the water pipe 42 from being separated from the water supply pipe 24 due to water pressure impact. The water pipe 42 also passes through the through hole on the bottom of the filter cartridge 3, and extends into the cleaning tank 1 through the water collection port 11 to connect with the spray arm 41. At this time, the deodorizing cover 43 is of course also located in the cleaning tank 1.

[0045] Figure 3 The first state of the cleaning device 10 with deodorizing function is shown, which is a state without water supply. At this time, the water pipe 42 is at the lowest position, and the deodorizing cover 43 covers the water collection port 11. When cleaning is needed, water enters the cleaning tank 1, and the water flows from the one-way valve 432 to the water collection cup 2 until it reaches a preset height. The circulation pump starts pumping water, and high-pressure water enters the water pipe 42 and the spray arm 41 through the water supply pipe 24. The spray arm 41 drives the water pipe 42 to move upward until the first protrusion 421 hits the second protrusion 241. At this time, the deodorizing cover 43 leaves the water collection port 11, allowing the spray arm 41 to rotate driven by the water flow, and cleaning begins. At this time, the water pipe 42 is driven by the spray arm 41 to rotate relative to the water supply pipe 24. This is as follows Figure 4 After the cleaning is completed and the water pump stops, the sprayer 4 drops down due to its own weight until it returns to the state shown in FIG. Figure 3 The first state is shown.

[0046] The filter cartridge 3 of this embodiment can be disassembled and assembled by simply pulling the water pipe 42 out of the water supply pipe 24 and then removing the filter cartridge 3 from the water pipe 42. When reinstalling the filter cartridge 3, the filter cartridge 3 only needs to be sleeved on the water pipe 42 and then the water pipe 42 is inserted into the water supply channel of the water supply pipe 24, so that the second protrusion 241 is elastically deformed and reset until the first protrusion 421 is located below the second protrusion 241. At this time, the filter cartridge 3 falls onto the rib 23.

[0047] The shower head 4 with the anti-odor cover and the cleaning device 10 with the anti-odor function in this embodiment can move the anti-odor cover 43 downward to cover the water collection port 11 when the water supply is cut off, thereby achieving the anti-odor effect.

[0048] Embodiment 2

[0049] See also Figure 5 , Figure 5 The sprayer 4 in the second embodiment is shown. Figure 5As shown, the sprayer 4 in the second embodiment includes a spray arm 41, a water pipe 42 and an anti-odor cover 43. The difference between the sprayer 4 in this embodiment and the sprayer in the first embodiment is that the spray arm 41 in this embodiment is vertically provided with an insertion tube 412 at the water inlet, and a limiting protrusion 413 is provided on the outer wall of the insertion tube 412. In this embodiment, the top of the water pipe 42 is open, and the anti-odor cover 43 is arranged on the outer wall of the water pipe 42 and connected to the water pipe 42 as a whole. At the position corresponding to the anti-odor cover 43, a limiting groove 424 for inserting the limiting protrusion 413 is provided in the water passage of the water pipe 42; in this embodiment, a stop groove 423 is also provided on the first protrusion 421 along the axial direction, and the stop groove 423 is located below the sealing ring groove 422. When the spray arm 41 in this embodiment is connected to the water pipe 42 , the limiting protrusion 413 is inserted into the limiting groove 424 , so that the spray arm 41 and the water pipe 42 establish an axially limited rotation connection relationship.

[0050] See also Figure 6 and Figure 7 , Figure 6 and Figure 7 A cleaning device 10 with a deodorizing function in the second embodiment is shown, which comprises a cleaning tank 1, a water collecting cup 2, a filter cartridge 3, a sprayer 4 as described above, a circulation pump and a sealing ring.

[0051] The cleaning tank 1 and the filter cartridge 3 in this embodiment are not different from the corresponding components in the first embodiment, and will not be described in detail here.

[0052] The water collecting cup 2 in this embodiment is different from the water collecting cup 2 in the first embodiment in that a stop rib 242 extending toward the water supply channel is provided on the inner wall at the water inlet of the water supply pipe 24 along the axis of the water supply pipe 24, and the stop rib 242 matches the stop groove 423 on the water pipe 42, so that the water pipe 42 and the water supply pipe 24 only have a sliding connection relationship and cannot rotate relative to each other.

[0053] After the cleaning device 10 with deodorizing function in this embodiment is connected, the first protrusion 421 at the bottom of the water pipe 42 is located in the water supply channel of the water supply pipe 24, and the anti-rotation rib 242 of the water supply pipe 24 is inserted into the anti-rotation groove 423 of the water pipe 42, so that the water pipe 42 and the water supply pipe 24 form a non-rotating sliding connection, and the sealing ring is located in the first sealing ring groove 422 and presses against the wall of the water supply channel to form a seal. After the first protrusion 421 is connected, it is also located below the second protrusion 241, so that the first protrusion 421 and the second protrusion 241 form an axial limiting structure to prevent the water pipe 42 from being separated from the water supply pipe 24 due to the impact of water pressure. The water pipe 42 also passes through the through hole on the bottom of the filter cartridge 3, and extends into the cleaning tank 1 through the water collection port 11 to connect with the spray arm 41. At this time, the deodorizing cover 43 is of course also located in the cleaning tank 1.

[0054] Figure 6The first state of the cleaning device 10 with deodorizing function is shown, which is a state without water supply. At this time, the water pipe 42 is at the lowest position, and the deodorizing cover 43 covers the water collection port 11. When cleaning is needed, water enters the cleaning tank 1, and the water flows from the one-way valve 432 to the water collection cup 2 until it reaches the preset height. The circulation pump starts pumping water, and the high-pressure water enters the water pipe 42 and the spray arm 41 through the water supply pipe 24. The spray arm 41 drives the water pipe 42 to move upward until the first protrusion 421 hits the second protrusion 241. At this time, the deodorizing cover 43 leaves the water collection port 11, so that the spray arm 41 is driven by the water flow to rotate and cleaning begins. At this time, since the water pipe 42 is non-rotatingly connected to the water supply pipe 24, the spray arm 41 rotates relative to the water pipe 42. This is as shown in FIG. Figure 7 After the cleaning is completed and the water pump stops, the sprayer 4 drops down due to its own weight until it returns to the state shown in FIG. Figure 6 The first state is shown.

[0055] The disassembly and assembly scheme of the filter cartridge 3 in this embodiment is the same as that in Embodiment 1. Of course, this embodiment also realizes the function of allowing the deodorizing cover 43 to move down to cover the water collection port 11 when the water supply is cut off, thus achieving a deodorizing effect.

[0056] Embodiment 3

[0057] See also Figure 8 , Figure 8 The sprayer 4 in the third embodiment is shown. Figure 8 As shown, the sprayer 4 in the third embodiment includes a spray arm 41, a water pipe 42 and an anti-odor cover 43. The sprayer 4 in this embodiment is different from the sprayer in the first embodiment in that at least two first protrusions 421 extending in the direction of the water passage are provided at the bottom of the water pipe 42, and the number of the first protrusions 421 in this embodiment is four. The water pipe 42 is no longer provided with a first sealing ring groove 422.

[0058] See also Fig. 9 and Fig.10 , Fig. 9 and Fig.10 A cleaning device 10 with a deodorizing function in the third embodiment is shown, which comprises a cleaning tank 1, a water collecting cup 2, a filter cartridge 3, a sprayer 4 as described above, a circulation pump and a sealing ring.

[0059] The cleaning tank 1 and the filter cartridge 3 in this embodiment are not different from the corresponding components in the first embodiment, and will not be described in detail here.

[0060] The water collecting cup 2 in this embodiment is different from the water collecting cup 2 in the first embodiment in that the outer wall of the water outlet end of the water supply pipe 24 is provided with a second protrusion 241 protruding outward, the second protrusion 241 is in the shape of a boss, and its outer wall is provided with a second sealing ring groove for accommodating a sealing ring.

[0061] After the cleaning device 10 with deodorizing function in this embodiment is connected, the first protrusion 421 at the bottom of the water pipe 42 is sleeved on the outside of the second protrusion 241 of the water supply pipe 24, so that the water pipe 42 and the water supply pipe 24 are rotatably connected and slidably connected, and the sealing ring is located in the second sealing ring groove and presses against the wall of the water passage to form a seal. After the first protrusion 421 is connected, it is located below the second protrusion 241, so that the first protrusion 421 and the second protrusion 241 form an axial limiting structure to prevent the water pipe 42 from being separated from the water supply pipe 24 due to the impact of water pressure. The water pipe 42 also passes through the through hole on the bottom of the filter cartridge 3, and extends into the cleaning tank 1 through the water collection port 11 to connect with the spray arm 41. At this time, the deodorizing cover 43 is of course also located in the cleaning tank 1.

[0062] Fig. 9 The figure shows the first state of the cleaning device 10 with deodorizing function, which is a state without water supply. At this time, the water pipe 42 is at the lowest position, and the deodorizing cover 43 covers the water collection port 11. When cleaning is needed, water enters the cleaning tank 1, and the water flows from the one-way valve 432 to the water collection cup 2 until it reaches a preset height. The circulation pump starts pumping water, and high-pressure water enters the water pipe 42 and the spray arm 41 through the water supply pipe 24. The spray arm 41 drives the water pipe 42 to move upward until the first protrusion 421 abuts against the second protrusion 241. At this time, the deodorizing cover 43 leaves the water collection port 11, so that the spray arm 41 is driven by the water flow to rotate and start cleaning. At this time, the water pipe 42 is also driven by the spray arm 41 to rotate relative to the water supply pipe 24. This is as follows Fig.10 After the cleaning is completed and the water pump stops, the sprayer 4 drops down due to its own weight until it returns to the state shown in FIG. Fig. 9 The first state is shown.

[0063] The disassembly and assembly of the filter cartridge 3 of this embodiment only requires pulling out the water pipe 42 from the water supply pipe 24, and then removing the filter cartridge 3 from the water pipe 42. When reinstalling the filter cartridge 3, it is only necessary to sleeve the filter cartridge 3 on the water pipe 42, and then sleeve the water pipe 42 on the second protrusion 241 of the water supply pipe 24, and elastically deform the first protrusion 421 and reset it until the first protrusion 421 is located below the second protrusion 241. At this time, the filter cartridge 3 falls on the rib 23. Of course, this embodiment also realizes the function of allowing the anti-odor cover 43 to move down to cover the water collection port 11 when the water is cut off, thereby achieving an anti-odor effect.

[0064] The above specification and description of the embodiments are used to explain the protection scope of the present application, but do not constitute a limitation on the protection scope of the present application.
