Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, in particular to a washing machine for washing tableware. Background Art

[0002] For front-loading dishwashers on the market, it is difficult to completely seal the door and liner components at the left and right lower corners, and some even have no seals. For dishwashers with closed water pumps, since one water pump needs to supply at least two layers of spray, the impact of the water flow is weak, and there is generally no leakage problem at the left and right lower corners of the door and liner components.

[0003] The applicant's prior patent ZL202023348766.9 "A dual pump system and a cleaning machine using the dual pump system" discloses a structure, in which the dual pump system includes an upper impeller, a lower impeller, an upper shell, a lower shell and a driving member, the upper shell having a first accommodating chamber for installing the upper part of the first blade, the upper part of the lower shell having a second accommodating chamber for installing the lower part of the first blade, a first water inlet for supplying water into the second accommodating chamber is opened on the side wall of the lower shell, a third accommodating chamber for installing the lower impeller is opened on the lower part of the lower shell, and a second water inlet and a water outlet are opened on the side wall and / or bottom wall of the lower shell; the cleaning machine includes a box body and a water supply pipe that can transport water at the bottom of the box body upward, the lower shell body is constrained on the bottom wall of the box body and the water outlet is connected to the lower end of the water supply pipe. The cleaning machine adopts the above-mentioned open dual-pump system, which utilizes two non-interfering volutes to independently supply water to the upper and lower spray arms. The water flow and stamping pressure are greatly improved. If a sealing structure is not provided at the left and right lower corners of the door assembly and the liner assembly, water leakage problems are likely to occur.

[0004] However, if a sealing gasket is simply added to block the water, since the space here is small and irregular, the sealing gasket is easily deformed when the door is opened or closed and is difficult to seal completely, resulting in some water flowing into the assembly space at the bottom of the door body assembly and the liner assembly after accumulation. Due to the blocking effect of the sealing gasket, the water entering the assembly space is difficult to flow back into the liner, resulting in more and more water accumulation until a serious overflow problem occurs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning machine that can guide the accumulated water back to the inner tank to avoid the corner overflow problem in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning machine, including an inner tank and a door body, the front edge and the side edge of the bottom of the inner tank extend vertically toward the front side to enclose a water accumulation area connected with the inner cavity of the inner tank, the bottom edge of the cleaning machine is provided with a first sealing strip that can abut the bottom of the door body against the bottom wall of the inner tank when the door is closed, the side edge of the cleaning machine is provided with a second sealing strip that can abut the side of the door body against the side wall of the inner tank when the door is closed, and a water guide member clamped between the bottom wall of the inner tank and the first sealing strip and the second sealing strip is provided at the corner where the water accumulation area is connected to the side wall of the inner tank, and the water guide member is provided with a guide channel for connecting the water accumulation area with the inner cavity of the inner tank.

[0007] Preferably, the water guide is formed into an L-shaped structure that matches the bottom corner of the cleaning machine, and the inner edge of the L-shaped structure smoothly transitions to form an arc-shaped guide surface. Preferably, the guide channel runs through the water guide, and the inner port is arranged corresponding to the guide surface, and the outer port is arranged corresponding to the corner of the L-shaped structure. The above structure is conducive to buffering and guiding the water that impacts the corner, avoiding overflow due to too rapid water flow.

[0008] Preferably, from a top view, the diversion channel is in a Z-shaped structure along the water flow direction, with the first end of the Z-shaped structure located on the diversion surface and the second end located at the corner of the L-shaped structure. With such a structure, the cleaning water sprayed by the spray arm will not rush into the water accumulation area immediately after entering the diversion channel, but will need to turn at a certain angle, thereby improving the water inrush at the left and right corners.

[0009] Preferably, in the closed state, there is a first gap between the end of the first sealing strip and the side wall of the inner container, the front wall of the door body abuts against the second sealing strip, and there is a second gap between the side wall of the door body and the side wall of the inner container, and the first gap and the second gap are connected to form a diversion cavity that surrounds the tip of the L-shaped structure of the water guide and the outer port of the diversion channel. The diversion cavity is conducive to further buffering the water gushing situation and guiding the accumulated water in the water accumulation area back to the inner container as soon as possible.

[0010] Preferably, the water guide is hollow inside to form a buffer cavity that surrounds the outer periphery of the guide channel and is relatively independent of the guide channel, and the inner side wall of the L-shaped structure is provided with an opening for water to enter the buffer cavity. This structure can buffer the water gushing toward the corner, reduce the turbulence of the water flow, and thus prevent a large amount of gushing water from leaking out.

[0011] Preferably, the water guide is provided with barrier ribs for enclosing a flow guide channel. The buffer cavity is provided with flow guide ribs extending from the edge to the inner side wall.

[0012] Preferably, a sheet metal piece extending vertically is provided at the side edge of the inner container, the second sealing strip is provided on the outside of the sheet metal piece, a space for installing a water guide is provided between the bottom of the sheet metal piece and the bottom wall of the inner container, the lower end of the second sealing strip abuts against the upper surface of the water guide, and a positioning piece extending vertically and clamped between the sheet metal piece and the second sealing strip is provided at the top edge of the water guide. The above structure facilitates the installation of the water guide and improves the sealing performance after assembly, allowing only accumulated water to flow through the diversion channel.

[0013] Preferably, a metal sheet extending into the water accumulation area and laterally covering the water accumulation area for condensing steam is provided on the top of the water guide. During the cleaning process, since there is at least one hot water for cleaning, hot water will flow into the left and right corners, and the steam carried by the hot water will easily rise into the door assembly to cause condensed water. The above-mentioned metal sheet is provided to block the steam on the one hand to prevent it from rising, and on the other hand to condense the steam so that it can flow back to the inner tank through the guide channel as condensed water as soon as possible.

[0014] Compared with the prior art, the advantages of the present invention are: the present invention changes the idea of ​​the prior art of sealing by blocking the outflow of gushing water, and instead allows the gushing water to flow out to the water accumulation area first, and then allows the accumulated water to flow back into the inner tank through the diversion channel, and adopts the idea of ​​"changing blockage to drainage" to seal the angle of the cleaning machine, thereby effectively avoiding the problem of angle overflow.

[0023] The present invention is further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 8 As shown, the cleaning machine of this embodiment includes an inner tank 1 and a door body 2. The front edge and the side edge of the bottom of the inner tank 1 extend vertically toward the front side to enclose a water accumulation area 10 connected to the inner cavity of the inner tank 1. Below the inner tank 1 is a cleaning machine base, which is provided with a water storage tank and an alarm device. An overflow port 101 is provided at the top edge of the water accumulation area 10, and the overflow port 101 is connected to the water storage tank of the base through an overflow pipe.

[0025] The bottom edge of the cleaning machine is provided with a first sealing strip 100 that can abut the bottom of the door body 2 against the bottom wall of the inner tank 1 when the door is closed. The first sealing strip 100 is constrained at the bottom edge of the door body 2. The side edge of the cleaning machine is provided with a second sealing strip 200 that can abut the side of the door body 2 against the side wall of the inner tank 1 when the door is closed. The second sealing strip 200 is usually constrained at the edge of the inner tank 1.

[0026] In this embodiment, a water guide member 3 is provided at the corner where the water accumulation area 10 is connected to the side wall of the inner tank 1, and is clamped between the bottom wall of the inner tank 1 and the bottom of the first sealing strip 100 and the bottom of the second sealing strip 200. The water guide member 3 is provided with a guide channel 31 for connecting the water accumulation area 10 with the inner cavity of the inner tank 1.

[0027] The water guide 3 is formed into an L-shaped structure that matches the bottom corner of the cleaning machine, and the inner edge of the L-shaped structure smoothly transitions to form an arc-shaped guide surface 32. The guide channel 31 runs through the water guide 3, and the inner port 311 is arranged corresponding to the guide surface 32, and the outer port 312 is arranged corresponding to the corner of the L-shaped structure. The above structure is conducive to buffering and guiding the water that impacts the corner, avoiding overflow due to too fast water flow.

[0028] From a top view, the flow guide channel 31 is in a Z-shaped structure along the water flow direction, with the first end of the Z-shaped structure located on the flow guide surface 32 and the second end located at the corner of the L-shaped structure. With such a structure, the cleaning water sprayed by the spray arm will not rush into the water accumulation area 10 immediately after entering the flow guide channel 31, but needs to turn at a certain angle, thereby improving the water inrush at the left and right corners.

[0029] In the closed state, there is a first gap 01 between the end of the first sealing strip 100 and the side wall of the inner container 1, the front wall of the door body 2 abuts against the second sealing strip 200, and there is a second gap 02 between the side wall of the door body 2 and the side wall of the inner container 1. The first gap 01 and the second gap 02 are connected to form a guide cavity that surrounds the tip of the L-shaped structure of the water guide member 3 and the outer port 312 of the guide channel 31. The above-mentioned guide cavity is conducive to further buffering the water gushing situation and guiding the accumulated water in the water accumulation area 10 back to the inner container 1 as soon as possible.

[0030] The water guide 3 is hollow inside to form a buffer cavity 33 that surrounds the outer periphery of the diversion channel 31 and is relatively independent of the diversion channel 31. The water guide 3 is provided with a barrier rib 313 for enclosing the diversion channel 31, and the inner side wall of the L-shaped structure is provided with an opening 331 for water to enter the buffer cavity 33. The buffer cavity 33 is provided with a diversion rib 332 extending from the edge to the inner side wall. This structure can buffer the water gushing toward the corner, reduce the turbulence of the water flow, and thus prevent a large amount of water from leaking out.

[0031] In this embodiment, a sheet metal part 4 extending vertically is provided at the side edge of the inner liner 1, a second sealing strip 200 is provided on the outer side of the sheet metal part 4, a space for installing the water guide 3 is provided between the bottom of the sheet metal part 4 and the bottom wall of the inner liner 1, the lower end of the second sealing strip 200 abuts against the upper surface of the water guide 3, and a positioning piece 34 extending vertically and clamped between the sheet metal part 4 and the second sealing strip 200 is provided at the top edge of the water guide 3. The above structure facilitates the installation of the water guide 3 and improves the sealing after assembly, allowing only the accumulated water to flow through the diversion channel 31.

[0032] The top of the water guide 3 is provided with a metal sheet 5 extending into the water accumulation area 10 and laterally covering the water accumulation area 10 for condensing steam. During the cleaning process, since there is at least one hot water for cleaning, hot water will flow into the left and right corners, and the steam carried by the hot water will easily rise into the door assembly to cause condensed water. The above-mentioned metal sheet 5 is provided to block the steam on the one hand to prevent it from rising, and on the other hand to condense the steam so that it can flow back to the inner tank through the guide channel as condensed water as soon as possible.

[0033] The present embodiment changes the idea of ​​sealing by blocking the outflow of gushing water in the prior art, and instead allows the gushing water to flow out to the water accumulation area 10 first, and then allows the accumulated water to flow back to the inner tank 1 through the guide channel 31. The idea of ​​"changing blockage to drainage" is adopted to seal the angle of the cleaning machine, thereby effectively avoiding the problem of angle overflow.
