The specific structure of the sump dishwasher 1000 according to an embodiment of the present invention is described below with reference to fig. 1 to 14.

According to an embodiment of the present invention, a sump dishwasher 1000, as shown in fig. 1, includes a washing tub 600, a breather 100, and a water softener 400, in which a washing space having an open top is defined in the washing tub 600, and an appliance to be cleaned is placed in the washing space to be washed.

As shown in fig. 4 to 6, the water softener 400 includes a body 410 and a regeneration control member 470, wherein the body 410 defines a soft water chamber 420 and a soft regeneration chamber 430 which are communicated with each other, the regeneration control member 470 is used for controlling the communication and interception between the soft water chamber 420 and the soft regeneration chamber 430, a soft water inlet 411 and a soft water outlet 412 which are respectively communicated with both sides of the soft water chamber 420 are formed on the body 410, a regeneration water inlet 413 and a salt adding port 414 which are communicated with the soft regeneration chamber 430 are also formed on the body 410, the soft water inlet 411 and the regeneration water inlet 413 are used for introducing water, the soft water outlet 412 is communicated with the washing tank 600, and the salt adding port 414 is used for adding regeneration salt into the soft regeneration chamber 430.

The water flow direction in the water softener 400 has two routes: one route is that water can flow into the soft water chamber 420 from the soft water inlet 411, soften in the soft water chamber 420, and the softened water is discharged from the soft water outlet 412; alternatively, water may flow from the regeneration water inlet 413 into the softening regeneration chamber 430, absorbing salt in the softening regeneration chamber 430 to form brine, which then flows into the soft water chamber 420, and eventually the brine is discharged from the soft water outlet 412. When the salt in the softening regeneration chamber 430 is consumed to some extent, the regenerated salt is replenished from the salt adding port 414.

In general, when water is used daily by a person, it is derived from tap water, and the content of Cl, ca, mg and the like in tap water is high, and the daily appliance is washed with tap water, and the residual Cl, ca, mg and the like on the daily appliance are high, so that the water is easily taken in by the user.

In the embodiment of the present invention, the soft water chamber 420 may be filled with resin or other soft water capable of absorbing Cl, ca, mg and other ions, and the soft regeneration chamber 430 may be filled with regeneration salt, wherein the regeneration salt is preferably edible salt (mainly containing NaCl) for convenience of purchase. Of course, the regenerated salt may be any other substance that can wash out Cl, ca, mg and other ions from soft water, and is not limited thereto.

Specifically, when the washing tank 600 needs water, tap water enters the soft water chamber 420 through the soft water inlet 411, soft water in the soft water chamber 420 absorbs Cl, ca, mg plasma in the water, and the absorbed soft water flows into the washing tank 600 through the soft water outlet 412, i.e. the soft water in the soft water chamber 420 has the function of removing Cl, ca, mg plasma in the tap water.

When the soft water matter adsorbs Cl, ca, mg, etc. ions to be saturated, the adsorption effect of the soft water matter is lowered, and at this time, the soft water matter needs to be reduced. Tap water enters the soft water regeneration chamber 430 through the regenerated water inlet 413 of the water softener 400 to form brine, when the soft water adsorption capacity is reduced, the regeneration control member 470 can be controlled to be opened, so that the soft water chamber 420 is communicated with the soft water regeneration chamber 430, the brine in the soft water regeneration chamber 430 enters the soft water chamber 420, the brine flows into the soft water chamber 420 to be subjected to reduction treatment, the softening capacity of the resin is recovered, and the reduced brine is discharged from the soft water outlet 412. When the reduction is not required, the regeneration control member 470 is closed, so that the soft water chamber 420 is blocked from the soft water regeneration chamber 430, and the soft water chamber 420 can perform a soft water operation.

In some embodiments, the soft water inlet 411 and the regeneration water inlet 413 are the same inlet, and the water softener 400 is provided with a three-way valve at the soft water inlet 411 to control inflow water toward one of the soft water chamber 420 and the soft regeneration chamber 430. In some embodiments, the soft water inlet 411 and the reclaimed water inlet 413 are two independent inlets of the water softener 400, so that three-way valves are saved, which is beneficial to reducing cost and simplifying structure. In addition, the water softener 400 has only one regeneration control 470, and the overall control is very simple. In the following description, the soft water inlet 411 and the reclaimed water inlet 413 are taken as two inlets of the water softener 400, which are independent from each other, respectively.

Specifically, as shown in fig. 6 and 4, the soft water chamber 420 and the soft water regeneration chamber 430 are horizontally disposed side by side, the soft water inlet 411 and the regeneration water inlet 413 are disposed side by side above the soft water chamber 420, and the soft water outlet 412 is located at an upper portion of the body 410. The arrangement is more reasonable in structure than the upper and lower distribution of the soft water chamber 420 and the soft water regeneration chamber 430.

Specifically, if the soft water chamber 420 and the soft water chamber 430 are distributed up and down, when the soft water chamber 420 is located above the soft water chamber 430, when the regeneration control member 470 is opened, the brine in the soft water chamber 430 automatically flows into the soft water chamber 420 with excessive consumption resistance; when the soft water regeneration chamber 430 is positioned above the soft water chamber 420, the water flow needs to flow through the long route for time consuming.

In fig. 4 to 6, the soft water chamber 420 is formed as a cylindrical chamber extending in the up-down direction, and the soft water regeneration chamber 430 is formed as a generally elongated chamber having a wide upper portion and a narrow lower portion.

According to the water softener 400 of the embodiment of the invention, the soft water cavity 420 and the soft regeneration cavity 430 which are mutually communicated are arranged in the inner cavity of the water softener 400, so that the softening treatment process and the reduction treatment process can be respectively carried out in the soft water cavity 420 and the soft regeneration cavity 430, and the normal operation of the water softener 400 is ensured. The water softener 400 has the advantages of simple and compact structure and reasonable layout, is favorable for realizing the division of different functional areas, and has high use reliability.

In some embodiments, as shown in fig. 5, the body 410 includes an upper cover 401, a lower cover 402, and a structure body 403, and the upper cover 401 and the lower cover 402 are respectively provided at upper and lower ends of the structure body 403, which may facilitate processing to form respective internal passages of the body 410. Wherein, the outer edge of the upper cover 401 is formed with an upturned edge extending downward and abutting with the upper end of the structural body 403, and the outer edge of the lower cover 402 is formed with a downturned edge extending upward and abutting with the lower end of the structural body 403.

In some embodiments, as shown in fig. 6, a water outlet buffer cavity 422 is disposed above a soft water cavity 420 in a body 410, a water inlet buffer cavity 425 is disposed below the soft water cavity 420, a soft water outlet 412 is communicated with the water outlet buffer cavity 422, a soft water inlet 411 and a soft water regeneration cavity 430 are both communicated with the water inlet buffer cavity 425, a water inlet buffer plate 426 is spaced between the soft water cavity 420 and the water inlet buffer cavity 425, a water outlet buffer plate 423 is spaced between the soft water cavity 420 and the water outlet buffer cavity 422, and water channels 421 are disposed on the water inlet buffer plate 426 and the water outlet buffer plate 423.

As shown in fig. 5 and 7, at least one of the water-in buffer plate 426 and the water-out buffer plate 423 is provided with a plurality of slits to constitute a grill, each slit being a part of the water passage 421, the width of the slit being smaller than the diameter of the resin particles. Alternatively, the width of the slit may be as large as 0.1-1.5mm, and thus the grating structure is provided to facilitate water passing and prevent resin particles from leaking out.

Specifically, the water outlet buffer plate 423 and the water inlet buffer plate 426 are circular plates, and the plurality of slits are circumferentially arranged around the axis of the soft water chamber 420, so that the liquid can uniformly enter the soft water chamber 420, thereby ensuring that the tap water can be uniformly softened, and the salt water can uniformly wash the resin particles. Of course, the arrangement of the slits is not limited to the arrangement circumferentially around the axis of the soft water chamber 420, but may be arranged in other irregular patterns.

Specifically, when the water-entering buffer plate 426 is provided with a slit, as shown in fig. 6, the width of the slit facing the water-entering buffer chamber 425 is greater than the width of the slit facing the soft water chamber 420. Thus, the liquid can be ensured to enter the soft water cavity 420 faster, and the resin particles can be prevented from leaking out. More specifically, in fig. 6, the width of the slit is gradually reduced in the direction from the water inflow buffer chamber 425 to the soft water chamber 420, and then is maintained.

Specifically, when the water outlet buffer plate 423 is provided with a slit, as shown in fig. 6, a width of the slit toward the water outlet buffer chamber 422 is greater than a width of the slit toward the soft water chamber 420. Thus, it is possible to ensure that the liquid leaves the soft water chamber 420 faster and also to prevent the resin particles from leaking out. More specifically, in fig. 6, the width of the slit is gradually reduced in the direction from the water discharge buffer chamber 422 to the soft water chamber 420, and then is maintained.

Further, as shown in fig. 6, a lower protrusion 427 is formed downward at the middle portion of the water inlet buffer plate 426, and the water passing passage 421 of the water inlet buffer plate 426 is provided at the lower protrusion 427. The soft water inlet 411 and the softening and regenerating chamber 430 are both communicated with the outer peripheral position of the water inlet buffer chamber 425, when water is introduced from the soft water inlet 411 or the softening and regenerating chamber 430, water flows around one circle under the guiding and guiding of the lower convex part 427, the water flows from the outer periphery to the lower part of the lower convex part 427 along the radial direction, and then the water flows upwards through the water channel 421 on the water inlet buffer plate 426. The lower protrusion 427 is beneficial to uniformly distributing the water flow of the water inlet soft water cavity 420 in the circumferential direction.

As shown in fig. 6, the middle portion of the water outlet buffer plate 423 is upwardly formed with an upper protrusion 424, and the water passing channel 421 of the water outlet buffer plate 423 is provided on the upper protrusion 424. The soft water outlet 412 is connected to the outer circumferential position of the outlet buffer chamber 422, and when the water flows out of the soft water chamber 420, the water flows in the outer circumferential direction after contacting the top, and then is collected at the soft water outlet 412 to be discharged. The provision of the upper protrusion 424 facilitates the uniform flow in the entire circumferential direction of the water outlet buffer chamber 422 when water is discharged, and facilitates the smooth flow of water.

Specifically, as shown in fig. 7, each slit is provided to extend in the radial direction of the soft water chamber 420. The extending direction of the slit is consistent with the flowing direction of the water flow, so that the flowing resistance is reduced, the liquid amount entering and exiting the soft water cavity 420 from the slit can be increased, and the softening speed of tap water or the washing speed of the resin particles by the salt water can be improved.

In some embodiments, as shown in fig. 4 and 5, the body 410 further defines a regeneration water inlet 440, the regeneration water inlet 440 is located at the outer side of the soft water cavity 420, and the regeneration water inlet 440 extends from the regeneration water inlet 413 to the softening regeneration cavity 430 and is communicated to the bottom of the softening regeneration cavity 430, so that when the regeneration water enters the water, the water flow flows from top to bottom, which can ensure smooth flow and avoid backflow. Because the regeneration salt or the salt water is contained in the softening and regenerating cavity 430, undissolved salt is easy to sink due to the higher density, so that the water flowing into the softening and regenerating cavity 430 flows from bottom to top, which is beneficial to fully dissolving the regeneration salt.

Specifically, as shown in fig. 4, the regeneration water inlet 440 extends vertically to the bottom wall of the body 410, and then extends to the softening regeneration chamber 430 after bypassing the soft water chamber 420 along the bottom wall of the body 410. The regeneration water inlet 440 is thus provided, and the regeneration water inlet 440 is easily formed when the body 410 is processed.

Specifically, as shown in fig. 4, 5 and 7, the regeneration water inlet 440 includes a vertical section 441, a surrounding section 442 and an inlet section 443, the vertical section 441 is located at the outer side of the soft water chamber 420 and extends vertically, the top of the vertical section 441 is a regeneration water inlet 413, the surrounding section 442 extends from the bottom end of the vertical section 441 along the circumferential wall of the soft water chamber 420 in a direction away from the soft water inlet 411, and the inlet section 443 is connected to the surrounding section 442 and communicates with the soft water regeneration chamber 430.

The vertical section 441 extends on the same vertical plane, and the surrounding section 442 and the inlet section 443 extend on the same horizontal plane, so that the housing structure is simplified, and the processing is convenient.

Further, as shown in fig. 7 and 8, a plurality of water through holes 444 are provided in the side wall of the regeneration water inlet passage 440 facing the softening regeneration chamber 430, and the water through holes 444 are provided in the peripheral wall of the inlet section 443. The regeneration water inlet 440 communicates with the softening regeneration chamber 430 only through the plurality of water through-holes 444, so that the regeneration salt in the softening regeneration chamber 430 is prevented from flowing into the regeneration water inlet 440. That is, the water passage 444 is provided to allow water to pass therethrough but to prevent salt leakage.

Specifically, as shown in fig. 5, the water passage holes 444 are formed as slits extending in the up-down direction.

Specifically, as shown in fig. 8, the water passage 444 has a larger flow area toward the end of the regeneration water inlet 440 than the end of the softening regeneration chamber 430. In this way, the water flowing in has a certain guiding function, but the regenerated salt can be well intercepted.

Specifically, as shown in fig. 8, the water passage 444 includes: the second straight hole section 4441 and the second cone section 4442, the second straight hole section 4441 is arranged adjacent to the softening regeneration chamber 430, the second cone section 4442 is arranged towards the regeneration water inlet channel 440, and the flow area of the second cone section 4442 is gradually reduced in the water flow direction. Wherein the flow area of the second straight hole section 4441 is unchanged in the water flow direction, and the second cone section 4442 forms a funnel shape. The arrangement of the second straight hole section 4441 ensures that the narrower part of the water through hole 444 has a certain thickness, and is not easy to deform and widen under the impact of water flow. The second cone 4442 is shaped like a funnel, which is beneficial to processing and shaping, and the water flow is quickened in the inflow process, so that the water flow flowing into the softening regeneration cavity 430 has a certain impact force, and the regenerated salt at the bottom is beneficial to being dispersed.

In some embodiments, as shown in FIG. 7, the access section 443 includes a main support 4431 extending along the bottom edge of the softening regeneration chamber 430, and the access section 443 further includes a branch 4432 connected to the main support 4431 and extending to the bottom center region of the softening regeneration chamber 430.

The main support 4431 extends along the bottom edge of the softening regeneration chamber 430, so that the main support 4431 and the softening regeneration chamber 430 share a side wall, which is beneficial to simplifying the structure and processing difficulty. And branch 4432 is provided to allow water flow into the middle region of the softening regeneration chamber 430. With the arrangement of main and branch 4431, 4432, the inflowing water is evenly distributed at the bottom of the softening regeneration chamber 430, which is advantageous for equalizing the brine concentration in the softening regeneration chamber 430.

Specifically, as shown in fig. 4, a plurality of water through holes 444 are provided on the side wall of the inlet section 443 facing the softening regeneration chamber 430, and water through holes 444 are provided on the side walls of the main branch 4431 and the branch 4432.

Specifically, as shown in fig. 4 and 9, the bottoms of the main support 4431 and the branch 4432 are flush with the bottom of the softening and regenerating chamber 430, and the tops of the main support 4431 and the branch 4432 are isolated from the softening and regenerating chamber 430, that is, the water through holes 444 are formed in the side walls of the main support 4431 and the branch 4432, and water flows flush into the softening and regenerating chamber 430 along the horizontal direction, so that the water flows upward after being uniformly distributed at the bottom of the softening and regenerating chamber 430 are facilitated. And the regenerated water rushing in the horizontal direction can impact regenerated salt at the bottom, which is beneficial to the full dissolution of the regenerated salt.

In some embodiments, as shown in fig. 5 and 9, a regeneration water outlet 450 is defined in the body 410, one end of the regeneration water outlet 450 communicates with the soft water chamber 420, and the other end of the regeneration water outlet 450 communicates with the soft water chamber 430.

Specifically, as shown in fig. 5, the regeneration water outlet 450 is vertically disposed between the soft water chamber 420 and the soft water chamber 430, the top end of the regeneration water outlet 450 is communicated with the soft water chamber 430, and the bottom end of the regeneration water outlet 450 is communicated with the soft water chamber 420.

This prevents the regenerated salt in the softening regeneration chamber 430 from flowing into the soft water chamber 420, and the water filtering holes 451 are provided to pass the brine but prevent the salt from leaking.

Specifically, as shown in fig. 9, the water filtering hole 451 has a larger flow area toward the end of the regeneration water outlet 450 than the flow area toward the end of the softening regeneration chamber 430. Thus, on the premise of salt leakage prevention, the water outlet of the salt water is ensured to be smoother. Since the water filtering hole 451 has a large flow area at the end facing the regenerated water outlet 450, the flow speed of the water becomes gentle, and the flow of the water is prevented from washing away the regenerated salt.

More specifically, as shown in fig. 9, the water filtering hole 451 includes: a first straight hole section 4511 and a first cone section 4512, the first straight hole section 4511 being disposed adjacent to the softening regeneration chamber 430, the first cone section 4512 being disposed toward the regeneration water outlet 450, the flow-through area of the first cone section 4512 gradually increasing in the direction of flow of water, the first cone section 4512 being formed in the shape of a funnel. The provision of the first straight hole portion 4511 ensures that the narrower portion of the water filtering hole 451 has a certain thickness and is not easily deformed and widened under the impact of water flow. The first cone 4512 is shaped to facilitate shaping, and the water flow slows down during inflow.

In fig. 9, at least a portion of the valve core 471 of the control valve may block the regenerant water outlet 450.

Specifically, a control valve is positioned between the soft water chamber 420 and the soft regeneration chamber 430, the control valve being mounted on the outer sidewall of the water inlet passage 460.

This arrangement facilitates the flow of the regeneration water outlet 450 from the lowermost end, and avoids liquid accumulation.

Alternatively, the on-off port 452 and the groove 453 are integrally formed by cutting with a drill, whereby the processing is very easy.

Further, as shown in fig. 9, an on-off tube 454 is provided on the side wall between the reclaimed water outlet 450 and the water inlet 460, and the orifice of the on-off tube 454 constitutes the on-off port 452. The on-off tube 454 extends away from the softening regeneration chamber 430, and the valve core 471 of the regeneration control member 470 mates with the channel tube 454. The provision of the on-off tube 454 can eliminate the need for the valve core 471 of the regeneration control member 470 to be set too long, reducing the overall size of the regeneration control member 470.
