Description

Technical Field

[0001] This disclosure relates to the field of dishwasher technology, and in particular to a condenser structure and a dishwasher. Background Technology

[0002] A dishwasher is a household appliance that automatically cleans dishes. During operation, high-temperature steam is generated in the inner drum of the dishwasher. The high-temperature steam accumulates in the cleaning chamber of the inner drum, which is not conducive to the rapid drying of dishes. Therefore, dishwashers are usually equipped with a condenser. The condenser uses a fan to draw the high-temperature steam into the condenser through the air inlet, where it is condensed and separated to form condensate, thus achieving the drying effect of the high-temperature steam.

[0003] Patent No. 2024215849250 discloses a household appliance, including a main body with an inner liner. A kick foot is provided on the lower front side of the main body, and the kick foot has a through mounting opening. The household appliance also includes a duct assembly and a water collection box. The duct assembly includes a duct shell and an exhaust fan. The duct shell has an exhaust port and a condensing duct. The condensing duct tends to extend from top to bottom. The upper end of the condensing duct is connected to the inner cavity of the inner liner through the exhaust port. The exhaust fan guides the humid and hot gas in the inner liner into the condensing duct through the exhaust port. The condensing duct can condense the humid and hot gas. The water collection box is detachably installed in the mounting opening and has a water collection cavity. When installed in the mounting opening, the water collection box is connected to the duct assembly so that the lower end of the condensing duct is connected to the water collection cavity.

[0004] In the aforementioned patent, condensate from household appliances flows through a condensation duct to a collection box for condensation collection. This requires users to clean the collection box regularly; otherwise, the accumulated water may breed bacteria and produce odors, especially in hot and humid environments, increasing the maintenance burden on users. Utility Model Content

[0005] In view of the shortcomings or problems existing in the prior art, this disclosure provides a condenser structure that can effectively condense water vapor.

[0006] The technical solution adopted by this disclosure to solve the above-mentioned technical problem is as follows: a condenser structure, including a shell, a condensation chamber provided in the shell, a condensation structure and a flow guiding structure provided in the condensation chamber, the condensation structure including multiple condensation channels, the flow guiding structure being provided at the end of the condensation channels, the flow guiding structure including a flow guide plate assembly and a water outlet, the water outlet being connected to the inner tank of a dishwasher, and the flow guide plate assembly being used to guide the condensate from the condensation structure to the water outlet.

[0007] In a preferred embodiment, the housing includes a substrate, and the condensation structure includes an inner side plate and an outer side plate disposed on the substrate. A plurality of protruding ridges are equidistantly disposed between the inner side plate and the outer side plate. The plurality of condensation channels include channels between adjacent protruding ridges, channels between the outer side plate and the protruding ridges, and channels between the inner side plate and the protruding ridges.

[0008] In a preferred embodiment, the condensation chamber is provided with an air inlet and a water outlet. The condensation channel includes an ascending flow channel and a descending flow channel. The ascending flow channel is provided at the air inlet, the descending flow channel is provided at the water outlet, and a flow guiding structure is provided at the water outlet.

[0009] In a preferred embodiment, the convex rib includes a first end and a second end. The first end is disposed at the air inlet end, and the second end is disposed at the water outlet end. The ends of the first ends of the plurality of convex ribs are flush in the horizontal direction, and the ends of the second ends are distributed in a stepped manner in the horizontal direction, and decrease sequentially along the direction from the outer side plate to the inner side plate. The water outlet is located below the second end of the convex rib.

[0010] In a preferred embodiment, the guide plate assembly includes a first guide plate that is inclinedly disposed on a substrate. A first end of the first guide plate is connected to an outer side plate, and a second end is located above the water outlet. The height of the first end of the first guide plate is greater than the height of the second end.

[0011] In a preferred embodiment, the protrusion provided near the outer side plate is a first protrusion, the protrusion adjacent to the first protrusion is a second protrusion, the plane where the second end of the first protrusion and the second end of the second protrusion are located is a first plane, and the first guide plate is parallel to the first plane.

[0012] In a preferred embodiment, the guide plate assembly further includes a second guide plate disposed on the substrate.

Therefore, the above terms should not be construed as a limitation of this utility model.

[0026] Please refer to Figure 1 and Figure 2 As shown, this application provides a condenser structure, including a housing 1, a condensation chamber within the housing 1, a condensation structure and a flow guiding structure within the condensation chamber, the condensation structure including multiple condensation channels 2, and the flow guiding structure located at the end of each condensation channel 2. The flow guiding structure includes a flow guide plate assembly and a water outlet 3, the water outlet 3 being connected to the dishwasher inner tub. The flow guide plate assembly guides the condensate from the condensation structure to the water outlet 3. In this application, the water outlet 3 of the condenser is connected to the dishwasher inner tub, allowing the condensed water to directly enter the inner tub through the water outlet 3 and then into the water cup assembly for condensate recycling. Furthermore, the direct connection between the water outlet 3 and the inner tub shortens the drainage path, reducing pipe resistance and leakage risk. The condenser structure of this application is simple, eliminating the need for other devices to hold the condensate. The flow guide plate assembly guides the condensate to flow in a specific direction, preventing condensate accumulation in the condensation chamber, thereby reducing water accumulation and lowering maintenance frequency.

[0027] Specifically, the housing 1 includes a base plate, and the condensation structure includes an inner side plate 6 and an outer side plate 7 disposed on the base plate. Several protruding ribs 5 are equidistantly arranged between the inner side plate 6 and the outer side plate 7. Multiple condensation channels 2 include channels between adjacent protruding ribs 5, channels between the outer side plate 7 and the protruding ribs 5, and channels between the inner side plate 6 and the protruding ribs 5. The base plate, inner side plate 6, and outer side plate 7 are formed by hot-plate welding. The inner walls of the multiple condensation channels 2 (including the surfaces of the protruding ribs 5) are the sites for heat exchange between the high-temperature airflow and the condensation structure. Compared to a single planar condensation structure, this arrangement increases the condensation surface area, allowing the high-temperature airflow more opportunities to contact the condensation surface, thereby improving condensation efficiency. Furthermore, the arrangement of multiple condensation channels 2 causes the airflow, after entering from the inlet, to be divided into multiple streams, flowing separately in each condensation channel 2. This dispersed airflow path avoids localized excessively fast or slow airflow, ensuring a more uniform condensation effect throughout the entire condensation chamber.

[0028] Specifically, the condensing chamber is equipped with an air inlet and a water outlet. The condensing channel 2 includes an ascending flow channel 8 and a descending flow channel 9. The ascending flow channel 8 is located at the air inlet, and the descending flow channel 9 is located at the water outlet. A flow guide structure is located at the water outlet. Hot steam tends to rise. The high-temperature airflow entering from the air inlet rises along the ascending flow channel 8. By placing the ascending flow channel 8 at the air inlet, the high-temperature airflow has a longer contact time with the condensing channel 2 during its ascent, thus ensuring sufficient contact between the high-temperature airflow and the inner wall of the ascending flow channel 8, thereby improving condensation efficiency. After condensate forms in the ascending flow channel 8, it adheres to the inner wall of the channel as the airflow rises. When the airflow enters the descending flow channel 9, the condensate flows downward along the inner wall of the channel under the action of gravity, eventually flowing to the water outlet 3. This arrangement effectively reduces the backflow and accumulation of condensate in the condensing chamber, improving condensation efficiency. Preferably, the length of the rising section flow channel 8 is shorter than that of the falling section flow channel 9. The longer falling section flow channel 9 ensures that the condensate flows fully under the action of gravity, reducing the accumulation of condensate in the condensation chamber. At the same time, the longer falling section flow channel 9 can further extend the contact time between the high-temperature airflow and the surface of the condensation structure, allowing the water vapor in the airflow to condense more fully.

[0029] The protruding rib 5 has an arc-shaped section, comprising a first end and a second end. The arc-shaped section is located between the first and second ends. The first end is located at the air inlet, and the second end is located at the water outlet. The ends of the first ends of several protruding ribs 5 are flush in the horizontal direction, while the ends of the second ends are distributed in a stepped manner in the horizontal direction, decreasing sequentially from the outer side plate 7 to the inner side plate 6. The water outlet 3 is located below the second end of the protruding rib 5. Since the condensate is subject to gravity during flow, the stepped structure ensures that the condensate does not accumulate in a localized area, thereby reducing the interference of condensate on the condensation process.

[0030] The guide plate assembly includes a first guide plate 12 inclinedly disposed on a substrate. The first end of the first guide plate 12 is connected to the outer side plate 7, and the second end is located above the outlet 3. The height of the first end of the first guide plate 12 is greater than the height of the second end. A protruding rib 5 near the outer side plate 7 is a first protruding rib, and a protruding rib 5 adjacent to the first protruding rib is a second protruding rib. The plane where the second ends of the first and second protruding ribs are located is a first plane. Preferably, the first guide plate 12 is parallel to the first plane, that is, the inclination angle of the first guide plate 12 is parallel to the direction in which the ends of the second ends of the protruding ribs 5 decrease sequentially in the horizontal direction. During the downward flow of condensate in the descending section flow channel 9, some condensate will fall onto the first guide plate 12. The inclined design of the guide plate can reduce the accumulation of condensate in the condensation channel 2 and quickly guide the condensate to the outlet 3, thereby achieving efficient condensation within a limited space.

[0031] Furthermore, the guide plate assembly also includes a second guide plate 13 disposed on the substrate. The second guide plate 13 is an arc-shaped plate, with an inner concave surface facing the center and an outer convex surface away from the center. The inner surface of the arc-shaped plate faces the descending flow channel 9, and the outlet 3 is located on the inner surface of the arc-shaped plate. The second guide plate 13 is disposed below the outlet 3, serving two purposes: firstly, to block the condensate from flowing further downwards past the outlet 3; and secondly, to guide the condensate as it flows along the inner concave surface of the arc-shaped plate, ultimately converging at the outlet 3, thus preventing backflow or accumulation of condensate in the condensation chamber and improving the operating efficiency of the condenser. Preferably, a support plate 10 is also disposed on the substrate. The first end of the second guide plate 13 is connected to the inner plate 6, and the second end is connected to the support plate 10. Since the second guide plate 13 is subjected to long-term impact from condensate, the support plate 10 can effectively support the second guide plate 13. The second end of the first guide plate 12 is located between the first and second ends of the second guide plate 13 to ensure that the first guide plate 12 can accurately guide the condensate to the outlet 3.

[0032] Please refer to Figure 3 and Figure 4 As shown, this application also provides a dishwasher, including an inner tub. The aforementioned condenser structure is disposed on the outer side of the inner tub. A through hole is provided at the lower part of the inner tub, and the water outlet 3 is connected to the through hole, allowing condensate to enter the inner tub and then into the water cup assembly, thus realizing the recovery of condensate. A breather 11 is also provided on the inner tub. The air inlet of the breather 11 is connected to the interior of the inner tub, and the air outlet of the breather 11 is connected to the air inlet of the condensation chamber. Hot airflow in the dishwasher inner tub enters the condenser structure through the breather 11.
