Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A dishwasher 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 7.

As shown in fig. 1, 2 and 3, the dishwasher 100 may generally include a first tub 10, a blow-dry assembly 20, and an exhaust overflow 30.

Specifically, as shown in fig. 1, 2 and 3, the first water tank 10 is formed with a first cavity, and the first water tank 10 has a first air inlet 11 and a first air outlet 12. The first cavity in the first water tank 10 is used for washing articles to be washed, when the dishwasher 100 washes the articles, water enters the first cavity of the dishwasher 100, most of the water in the dishwasher 100 is discharged after the dishwasher 100 finishes washing, and a small part of the water is attached to the articles to be washed, the side wall of the first cavity and the door cover 50 for sealing the first cavity in the form of water drops, a strand of water flow and water vapor. At this moment, need dry in the first cavity to breed the bacterium, through setting up first air intake 11 and first air outlet 12, accelerate the air in the first cavity and flow, thereby accelerate the evaporation of the moisture in the first cavity, reach dry purpose.

The air supply drying assembly 20 is communicated with the first air inlet 11 to supply air into the first cavity. In other words, the air supply drying assembly 20 supplies air into the first cavity through the first air inlet 11, and then is discharged from the first air outlet 12, and partial water vapor in the first cavity can be taken away by the air flow entering the first cavity, so that a drying effect is achieved.

Further, the exhaust overflow 30 has a first inlet 306, the first inlet 306 is communicated with at least one of the first intake vent 11 and the first exhaust vent 12, and the exhaust overflow 30 has a first outlet 301 for exhausting and draining air. Taking the exhaust overflow 30 as an example of being communicated with the first outlet 12, the exhaust overflow 30 further has a first inlet 306 communicated with the first outlet 12, and the wind exhausted through the first outlet 12 enters the exhaust overflow 30 through the first inlet 306 and is exhausted through the first outlet 301 of the exhaust overflow 30.

It can be understood that, due to the first air inlet 11 and the first air outlet 12 provided on the dishwasher 100, during the washing process of the dishwasher 100, there may be a case of overflowing through the first air inlet 11 or the first air outlet 12, especially a case of high water level inside the dishwasher 100, and water in the first cavity may be discharged through the first air inlet 11 or the first air outlet 12.

To avoid short circuiting the circuit when overflowing, the present application provides a vent overflow 30 to protect the internal circuitry of the dishwasher 100. Taking the exhaust overflow member 30 and the first air outlet 12 as an example, at this time, the first air inlet 11 is higher than the first air outlet 12, so that the first air outlet 12 overflows, in other words, the first air inlet 11 is disposed at the upper portion of the first water tank 10, and the first air outlet 12 is disposed at the lower portion of the first water tank 10, so that the air entering the first cavity from the first air inlet 11 can be blown to the door 50, and the door 50 is dried. When the overflow condition occurs, the water in the first cavity is discharged to the exhaust overflow member 30 through the first outlet 301, the water entering the exhaust overflow member 30 is discharged through the first outlet 301, and the first outlet 301 is communicated with the overflow drain pipe 60 and flows to the sewer through the overflow drain pipe 60.

That is, the exhaust overflow 30 plays a role of exhausting and draining, and integrates the exhausting function and the draining function into one component, so that the cost can be saved, and the assembly is also facilitated.

Therefore, according to the dishwasher 100 of the embodiment of the present invention, the dishwasher 100 has the first air inlet 11 and the first air outlet 12, and the exhaust overflow member 30 is communicated with the first air inlet 11 or the first air outlet 12, so that the safety factor of the dishwasher 100 can be improved, and the cost can be saved.

In some embodiments, as shown in fig. 7, the exhaust overflow 30 has a water blocking rib 32 extending upward from the bottom of the exhaust overflow 30, the water blocking rib 32 divides the inner space of the exhaust overflow 30 into a blowing chamber 304 and a water passing chamber 305, the blowing chamber 304 is communicated with the upper portion of the water passing chamber 305 and is separated from the lower portion thereof, the first outlet 12 is communicated with the blowing chamber 304, and the first outlet 301 is communicated with the water passing chamber 305. In other words, the exhaust overflow 30 has a blowing chamber 304 and a water passing chamber 305 inside, and the blowing chamber 304 and the water passing chamber 305 are separated by the water blocking rib 32, wherein the blowing chamber 304 communicates with the first outlet 12, and the upper end of the blowing chamber 304 communicates with the upper end of the water passing chamber 305. Thus, the water flowing into the exhaust overflow 30 from the first outlet 12 enters the air blowing chamber 304, then enters the water passing chamber 305 through the gap between the water blocking rib 32 and the exhaust overflow 30, and then is discharged through the first outlet 301 communicated with the water passing chamber 305. Therefore, the exhaust overflow member 30 is internally divided into the air supply cavity 304 and the water passing cavity 305, so that the exhaust overflow member 30 can work normally during exhaust and drainage, and the functions of the exhaust overflow member 30 are diversified.

In some alternative embodiments, as shown in fig. 7, the bottom surface of the water passing chamber 305 extends downward below the first outlet 301 in a direction toward the first outlet 301. In this way, the height of the bottom surface of the water passing cavity 305 is gradually reduced in the direction close to the first outlet 301, so that the water flow can naturally flow to the first outlet 301 under the action of gravity, and the water flow is convenient to flow out. In addition, by limiting the bottom surface of the water passing chamber 305 to be disposed below the first outlet 301, the bottom surface of the water passing chamber 305 may be flush with the bottom of the first outlet 301, and the bottom surface of the water passing chamber 305 may be slightly higher than the bottom of the first outlet 301 but lower than the top of the first outlet 301.

In some alternative embodiments, as shown in fig. 4, 5 and 7, the top of the exhaust overflow 30 has a second outlet 302, and the second outlet 302 communicates with the plenum chamber 304. Thus, since the exhaust overflow 30 has the second outlet 302 at the top, most of the air flow entering the air supply chamber 304 from the first air inlet 11 is discharged through the second outlet 302 at the top of the exhaust overflow 30, and the other part of the air flow enters the water passing chamber 305 communicating with the air supply chamber 304 and is discharged through the first outlet 301. Furthermore, in the event of a limited overflow condition of sewer blockage, the water flow cannot exit into the sewer through the first outlet 301, at which time the water flow can exit through the second outlet 302 located at the top of the exhaust overflow 30.

In one embodiment, a filter screen (not shown) is disposed at the second outlet 302. By providing the filter screen, it is possible to prevent dust, insects and small animals from entering the dishwasher 100 through the second outlet 302 to contaminate the dishwasher 100.

In some embodiments, as shown in fig. 1, 2 and 3, the dishwasher 100 further includes a second water tank 40, the second water tank 40 having a second cavity, the second water tank 40 having a second intake vent 401, the exhaust overflow 30 having a third outlet 303, the third outlet 303 communicating with the second intake vent 401. In this application, the air supply drying component 20 can supply hot air to the first cavity for drying speed in the first cavity, and thus, the partial air flow entering the exhaust overflow part 30 from the first air inlet 11 can flow to the second air inlet 401 through the third outlet 303 and flow into the second cavity to dry the articles in the second cavity, so that the recycling effect is achieved, and the resource utilization rate is improved. The second air inlet 401 is connected to the third outlet 303 through the connecting pipe 70, and since the air entering the connecting pipe 70 is hot air, the hot air may be condensed when contacting the connecting pipe 70, that is, the connecting pipe 70 plays a role of dehumidification, so that the air flow entering the second chamber is still relatively dry, and the condensed water may flow to the exhaust overflow 30 through the connecting pipe 70 and then be discharged through the first outlet 301. In addition, when a high water level overflow condition occurs in the second water tank 40, the water flow may be discharged from the second chamber to the exhaust overflow 30 through the second air inlet 401 and discharged to the sewer through the first outlet 301, and when a limit water level overflow condition in which the sewer is blocked occurs in the second water tank 40, the water flow may be discharged from the second chamber to the exhaust overflow 30 through the second air inlet 401 and discharged through the second outlet 302.

In some embodiments, as shown in fig. 1, 2 and 3, the top of the exhaust overflow 30 has a second outlet 302, the second outlet 302 is communicated with the blowing cavity 304, and the second inlet 401 is higher than the second outlet 302. According to the principle of communicating pipe, by disposing the second air inlet 401 above the second outlet 302, it is possible to avoid that water flows into the second chamber through the third outlet 303 to be wetted or cause secondary pollution to the articles in the second chamber in the case of extreme overflow.

In some alternative embodiments, as shown in fig. 4, 5, 6 and 7, the third outlet 303 is higher than the first outlet 301. In this way, the condensed water flows back into the exhaust overflow 30 through the third outlet 303, and the condensed water flowing back into the exhaust overflow 30 can be discharged through the first outlet 301 located below the third outlet 303.

In some embodiments, as shown in fig. 7, the exhaust overflow 30 has a plurality of air guiding ribs extending in the up-down direction, and the plurality of air guiding ribs are disposed around and spaced apart from the upper portion of the first inlet 306. The air guiding ribs guide the air flow entering the exhaust overflow member 30, so that the air flow in the exhaust overflow member 30 can be discharged out of the exhaust overflow member 30 along a predetermined direction. For example, the air guiding ribs are arranged perpendicular to the second outlet 302, so that the air flow can vertically pass through the second outlet 302 to be discharged out of the exhaust overflow member 30 through the air guiding function of the air guiding ribs, and the exhaust efficiency is improved. Wherein, a plurality of air guide ribs encircle first import 306 and interval arrangement, can divide into the stranded with the air current, make the wind-guiding effect better.

In some embodiments, as shown in fig. 4, 5, 6, and 7, the first outlet 301 is located at a lower portion of the exhaust overflow 30. Thus, the liquid entering the exhaust overflow member 30 can be conveniently discharged, and the residue can be avoided.

In some embodiments, as shown in fig. 1 and 2, the first water tank 10 is further provided with a water guiding groove 80, the water guiding groove 80 is located below the exhaust overflow member 30, and the water guiding groove 80 is inclined in the up-down direction. Thus, the water overflowing through the exhaust overflow member 30 is received by the water chute 80 and flows along the predetermined track under the action of gravity, so as to prevent the water flowing out of the exhaust overflow member 30 from overflowing out of order to spread and contaminate the bottom surface or cause short circuit to the electrical components in the bottom cover 90. The water guiding groove 80 may be connected to the first water groove 10, the first water groove 10 may be disposed around the exhaust overflow 30, and further, the water guiding groove 80 may be disposed vertically or obliquely to the first water groove 10 or the exhaust overflow 30.

In alternative embodiments, the water chute 80 has a cross-section that is at least one of U-shaped, V-shaped, and L-shaped. For example, the water chute 80 is a U-shaped water chute 80, and the U-shaped water chute 80 can guide the flow conveniently. Of course, the above embodiments are only illustrative and should not be construed as limiting the scope of the present invention, for example, the cross section of the water chute 80 may also be E-shaped, F-shaped, etc.

In some embodiments, as shown in fig. 1, 2 and 3, the first wind inlet 11 is disposed at an upper portion of the first water tank 10, and the first wind outlet 12 is disposed at a lower portion of the first water tank 10. From this, 11 air intakes of first air intake can be to covering the door closure 50 of locating first cavity and blow, carry out the drying to door closure 50, and because first air outlet 12 is located the lower part, can be so that the air current from last down flow, take away more vapor, improve drying efficiency.

In one embodiment, the dishwasher 100 includes a door cover 50, a first tub 10, an exhaust overflow 30, a bottom cover 90, a water guide 80, an overflow drain 60, a connection pipe 70, a second tub 40, and an overflow assembly of the second tub 40.

The exhaust overflow 30 has a specific structure including: the exhaust assembly comprises an exhaust assembly shell, a first outlet 301, a second outlet 302, a third outlet 303, a water retaining rib 32 and an air guide rib.

The exhaust overflow 30 is connected to the bottom of the first water tank 10 by a nut, the third outlet 303 of the exhaust overflow 30 is connected to the overflow port of the second water tank 40 by a connection pipe 70, and the first outlet 301 of the exhaust overflow 30 is connected to the sewer by an overflow drain pipe 60. The water chute 80 is welded to the bottom of the deep groove and is inclined downward to the left. The exhaust overflow member 30 is internally provided with a water retaining rib 32 and an air guiding rib for drainage guide and exhaust guide, respectively. The filter screen is arranged on the top of the exhaust overflow piece 30 and used for dust prevention and insect prevention.

The positions of the first air inlet 11 and the first air outlet 12 may be opposite or not, that is, the positional relationship between the exhaust overflow member 30 and the blower drying assembly 20 may be various. For example, the blow drying assembly 20 is located between the first sink 10 and the second sink 40, which may provide for greater integrity of the dishwasher 100.

During normal operation, when there is not high water level limit overflow, exhaust assembly normally works, and wind enters from the air inlet, goes out from the gas vent, and the second export 302 of top is discharged to most of wind, and a small part is discharged through connecting pipe 70 and overflow drain pipe 60, and the air current that gets into in the connecting pipe 70 can be at the pipeline condensation. The condensed water can flow into the sewer through the connection pipe 70 through the exhaust overflow 30 and through the first outlet 301.

When the high water level overflows, the water is discharged to the sewage through the overflow drain pipe 60. The overflow water can flow into the sewer through the connection pipe 70 through the exhaust overflow 30 and through the first outlet 301.

In extreme cases, when the sewer is blocked, water overflows from the top of the exhaust assembly and flows obliquely into the outside along the water chute 80 (the water chute 80 can prevent the water from flowing into the electric device of the dishwasher 100 along the bottom cover 90, so that the potential safety hazard of the electric device is ensured).
