Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a sink overflow seat structure and an integrated sink dishwasher. Background Art

[0002] Dishwashers have become one of the indispensable household appliances in modern kitchens because of their advantages of saving time and effort, cleaning thoroughly, disinfecting thoroughly, saving energy and electricity, etc. Existing dishwashers mostly have exhaust ports on the door panels, but high-temperature steam can easily enter the door panels from the exhaust ports, which can easily damage internal parts after long-term use. At the same time, high-temperature water vapor can easily flow into the cabinets from the sides, which can easily damage the cabinets. In addition, the exhaust holes are small, which indirectly affects the drying effect of the dishwasher.

[0003] Therefore, integrated sink dishwashers integrated with sinks have appeared on the market. The exhaust port of the high-temperature steam in the dishwasher is connected to the overflow port of the sink. However, in order to prevent excessive water accumulation in the sink, the overflow port needs to be connected to the sewer pipe. Therefore, high-temperature steam can easily enter the sewer pipe directly through the overflow port, accumulate a large amount of high-temperature steam in the sewer pipe, and then flow upward through the drain port at the bottom of the sink in the sewer pipe, affecting the user experience. Utility Model Content

[0004] Based on this, the utility model provides a water tank overflow seat structure for the above-mentioned technical problems.

[0005] A sink overflow seat structure comprises: a seat body, a chamber is constructed in the seat body, a first connecting port, a second connecting port and an overflow port are provided on the cavity wall of the cavity, and the overflow port is used to communicate with the sink; a first connecting pipe, one end of which is connected to the seat body and communicated with the first connecting port, and the other end is used to connect to a dishwasher for water vapor circulation; a second connecting pipe, one end of which is connected to the seat body and communicated with the second connecting port, and the other end is used to communicate with a sewer pipe; wherein the seat body also includes a stop plate, which is connected to the cavity wall of the chamber and is located between the first connecting port and the second connecting port.

Because a second connecting port connected to the sewer pipe is provided on the cavity wall of the chamber, when there is too much water in the sink, the stored water can enter the sewer pipe through the second connecting port on the overflow seat, thereby preventing the stored water in the sink from overflowing. In order to solve the problem that the high-temperature water vapor flowing out of the first connecting port directly enters the sewer pipe through the second connecting port, the present application adds a stopper plate, which is provided between the first connecting port and the second connecting port, and blocks the path of the water vapor flowing directly from the first connecting port to the second connecting port, so as to reduce the amount of water vapor entering the second connecting port, so that more water vapor flows out from the overflow port instead of entering the sewer pipe. At the same time, the stopper plate can also form a stopper effect on the flow of the odor in the sewer pipe toward the first connecting port, thereby preventing the odor in the sewer pipe from returning to the dishwasher. The baffle plate can also provide support for the overflow seat, improve its structural strength and make it more durable. In addition, when the water in the sink rises to the position of the baffle plate, the baffle plate will break the tension of the water surface, allowing the water to flow down faster, thus enhancing the siphon effect of the sewer pipe.

[0031] The utility model provides a sink overflow seat structure 100, which blocks high-temperature steam from directly entering the sewer pipe 203 by setting a stop plate 12, thereby preventing a large amount of high-temperature steam from flowing out of the sewer port at the bottom of the sink 201.

[0032] See also Figure 1-Figure 3 The sink overflow seat structure 100 includes a seat body 10, a first connecting pipe 20 and a second connecting pipe 30. A chamber 11 is constructed in the seat body 10. A first connecting port 111, a second connecting port 112 and an overflow port 113 are provided on the cavity wall of the cavity 11, and the overflow port 113 is used to communicate with the sink 201; one end of the first connecting pipe 20 is connected to the seat body 10 and communicates with the first connecting port 111, and the other end is used to connect with the dishwasher 202 for water vapor circulation; one end of the second connecting pipe 30 is connected to the seat body 10 and communicates with the second connecting port 112, and the other end is used to communicate with the sewer pipe 203; wherein the seat body 10 also includes a stop plate 12, which is connected to the cavity wall of the cavity 11 and is located between the first connecting port 111 and the second connecting port 112.

[0033] In this way, a first connecting port 111 connected to the dishwasher 202 is opened on the cavity wall of the chamber 11, so that the high-temperature water vapor flowing out of the dishwasher 202 can enter the chamber 11, and an overflow port 113 is also opened on the cavity wall of the chamber 11, so the water vapor can flow out from the overflow port 113. Because a second connecting port 112 connected to the sewer pipe 203 is opened on the cavity wall of the chamber 11, when there is too much water in the water tank 201, the stored water can enter the sewer pipe 203 through the second connecting port 112 on the overflow seat, thereby preventing the stored water in the water tank 201 from overflowing. In order to solve the problem that the high-temperature water vapor flowing out of the first communication port 111 directly enters the sewer pipe 203 through the second communication port 112, the present application adds a stopper plate 12, which is arranged between the first communication port 111 and the second communication port 112 to block the path of water vapor directly flowing from the first communication port 111 to the second communication port 112, so as to reduce the amount of water vapor entering the second communication port 112, so that more water vapor flows out from the overflow port 113 instead of entering the sewer pipe 203, and at the same time, the stopper plate 12 can also form a stopper effect on the flow of odor in the sewer pipe 203 toward the first communication port 111, so as to prevent the odor in the sewer pipe 203 from returning to the dishwasher 202. In addition, the stopper plate 12 can also provide a support effect for the overflow seat, improve its structural strength, and make it more durable. In addition, when the water in the water tank 201 rises to the position where the stopper plate 12 is located, the stopper plate 12 will destroy the tension of the water surface, allowing the water to flow downward faster, thereby enhancing the siphon effect of the sewer pipe 203.

[0034] Further, the cavity wall of the chamber 11 has a top wall, a bottom wall 115 and a side wall 116, the top wall is located at the top of the chamber 11, the side walls 116 are located on both sides of the chamber 11 in the horizontal direction, and the bottom wall 115 is located at the bottom of the chamber 11; the second communication port 112 is opened on the bottom wall 115; the first communication port 111 is opened on the top wall, and / or the first communication port 111 is opened at one end of the side wall 116 close to the top wall. In this way, since the sewer pipe 203 is located below the sink 201 as a whole, the second communication port 112 is opened on the bottom wall 115, which is convenient for it to communicate with the sewer pipe 203. For the second communication port 112 opened on the bottom wall 115, the first communication port 111 is opened on the side wall 116 or the top wall, which can facilitate the setting of the stopper 12 and also facilitate the high-temperature steam discharged from the dishwasher 202 during drying to flow out from the overflow port 113.

[0035] In this embodiment, the first connecting port 111 is opened on the side wall 116. In other embodiments, the first connecting port 111 can also be opened on the top wall and arranged opposite to the second connecting port 112, or two connecting ports can be arranged at the same time to communicate with the dishwasher 202, both of which can achieve technical effects.

[0036] The stopper plate 12 is arranged in the horizontal direction, so that the stopping effect for the second connecting port 112 opened on the bottom wall 115 is the best. Both ends of the stopper plate 12 in the length direction are spaced from the side wall 116, so that when there is too much water vapor and the flow effect of the overflow port 113 cannot meet the speed of the water vapor generated by the dishwasher 202, part of the water vapor is allowed to flow from the gaps on both sides of the stopper plate 12 to the second connecting port 112 and enter the sewer pipe 203.

[0037] The seat body 10 further includes at least two spaced apart positioning posts 13, which are connected to the cavity wall of the chamber 11 and extend in the horizontal direction, and a positioning hole 131 is provided at the axis position of the positioning post 13. Thus, the positioning post 13 is used to connect the seat body 10 with the side wall 116 of the water tank 201, and the positioning hole 131 in the positioning post 13 can be inserted into a connecting piece such as a screw, so as to realize the connection between the seat body 10 and the water tank 201.

[0038] Preferably, in this embodiment, both ends of the stop plate 12 are respectively connected to the two positioning columns 13. The positioning columns 13 facilitate the arrangement of the stop plate 12, can support the stop plate 12, and cooperate with the stop plate 12 to enhance the structural strength of the seat body 10.

[0039] In other embodiments, the stop plate 12 may also be provided separately, and does not have to be connected to the positioning column 13 .

[0040] In this embodiment, the outer side wall 116 of the positioning column 13 has an upper side 132 and a lower side 133, with the horizontal plane where the axis of the positioning column 13 is located as the boundary, the side of the positioning column 13 facing away from the second connecting port 112 is the upper side 132, and the side of the positioning column 13 facing the second connecting port 112 is the lower side 133, and both ends of the stop plate 12 are connected to the upper side 132 of the outer side wall 116 of the positioning column 13. In this way, as described above, the stop plate 12 can destroy the tension of the stored water to facilitate its discharge, so here the stop plate 12 is connected to the upper side 132 of the positioning column 13 (that is, the position of the stop plate 12 is higher), when the position of the stop plate 12 is higher, the siphon effect of the sewer pipe 203 is more obvious, so that the overflow speed of the second connecting port 112 increases, which greatly reduces the risk of water overflowing from the countertop when the sink 201 is filled with water.

[0041] It is understandable that the position of the stop plate 12 is not as high as possible, otherwise it is easy to affect the space for water vapor to be discharged. Therefore, in this embodiment, the stop plate 12 is connected to the positioning column 13, and the positioning column 13 is located in the middle of the seat body 10 in the vertical direction to ensure that the water vapor can be discharged smoothly. The stop plate 12 is located on the upper side 132 of the positioning column 13 to ensure that it helps the overflow effect, so that two technical effects are met at the same time.

[0042] Of course, if the working conditions require that the ability to discharge water vapor must be prioritized while the overflow effect must be weakened, the stop plate 12 can also be connected to the lower side 133 of the positioning column 13. This will not cause the sink overflow seat structure 100 to fail to achieve its effect. The position of the stop plate 12 should be flexibly adjusted according to work needs.

[0043] A reinforcing rib 14 is further provided between the positioning column 13 and the cavity wall of the chamber 11, one side of the reinforcing rib 14 is connected to the outer wall 116 of the positioning column 13 and extends along the axial direction of the positioning column 13, and the other side is connected to the cavity wall of the chamber 11. In this way, the reinforcing rib 14 further improves the structural strength of the positioning column 13 to prevent its deformation or shaking.

[0044] The side wall 116 of the seat body 10 is provided with a plurality of openings 15 in the horizontal direction, and the plurality of openings 15 are arranged at intervals along the edge of the overflow port 113. In this way, the seat body 10 is lightweight, consumables and costs are reduced, and the side wall 116 of the seat body 10 is made thinner, which facilitates demoulding and simplifies the process.

[0045] See also Figure 4-Figure 6 The utility model also provides an integrated sink dishwasher 200, as well as a sink 201, a dishwasher 202 and a sewer pipe 203. The sink overflow seat structure 100 is connected to the side wall 116 of the sink 201 and is connected to the sink 201 through the overflow port 113. One end of the first connecting pipe 20 is connected to the seat body 10, and the other end is connected to the dishwasher 202. One end of the second connecting pipe 30 is connected to the seat body 10, and the other end is connected to the sewer pipe 203. A sewer port is provided at the bottom of the sink 201, and the sewer port is connected to the sewer pipe 203.

[0046] Thus, the overall working process of the integrated sink dishwasher 200 is as follows: the sink 201 is used alone, and the overflow seat of the sink 201 is used to prevent the water in the sink 201 from overflowing from the countertop due to excessive water, and the water in the sink 201 can flow from the second connecting port 112 to the sewer pipe 203. When the integrated sink dishwasher 200 finishes working and enters the drying process, high-temperature water vapor is generated, and at this time, the high-temperature water vapor enters the chamber 11 in the seat body 10 through the first connecting pipe 20, flows out from the overflow port 113, and is stopped by the stop plate 12, and only a small amount of the water vapor enters the sewer pipe 203 through the second connecting port 112.

[0047] The side wall 116 of the water tank 201 has a passage 205, and the water tank 201 includes at least two connecting plates 204. Both ends of the connecting plates 204 are connected to the side wall 116 of the water tank 201, and the connecting plates 204 extend from one side of the passage 205 to the other side. The connecting plates 204 are provided with connecting holes 2041, and connecting members are passed through the connecting holes 2041 and extend into the positioning holes 131, thereby realizing the connection between the positioning column 13 and the connecting plates 204, thereby realizing the fixation of the water tank overflow seat structure 100.

[0048] Compared with the prior art, the utility model provides a stop plate 12 in the sink overflow seat structure 100. The stop plate 12 can not only reduce the amount of water vapor entering the chamber 11 from the first connecting port 111 and flowing to the second connecting port 112, but also prevent the odor in the second connecting port 112 connected to the sewer pipe 203 from being fed back into the dishwasher 202 through the first connecting port 111, and also strengthen the structural strength of the seat body 10, thereby improving the overall durability of the device.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
