Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and more specifically, to a condenser and a dishwasher. Background Technology

[0002] Dishwashers clean dishes by spraying them with hot water, and then dry them. During the washing phase, a large amount of hot, humid steam accumulates inside the drum. This steam is expelled through a breather to achieve pressure balance. During the drying phase, the hot, humid air inside the dishwasher needs to be quickly expelled. Current dishwashers typically use automatic door opening for steam venting or hot air drying. Automatic door opening releases steam by opening the door while the dishwasher is running, but this causes users to feel the steam while standing in front of the dishwasher, and a large amount of steam is directly released into the kitchen, creating smoke and moisture that negatively impacts the user experience. Hot air drying uses heating to rapidly evaporate water, effectively drying the surface moisture of the dishes. This generates a large amount of steam at high temperatures.

[0003] Therefore, existing dishwashers are equipped with condensers on the side walls of the inner drum to expel the steam generated during the washing and drying process. These condensers typically extend from the top of the inner drum towards the base, meaning the water outlet is located at the base, which can easily lead to condensate leaking outside the dishwasher. To improve this leakage problem, some condensers use a structure where the air outlet is located on the side of the inner drum. However, these air ducts are usually short, resulting in poor drying efficiency. This means the air exiting the outlet still carries steam, and when this air comes into direct contact with the cabinet, condensation occurs, which can lead to mold growth on the cabinet over time. Utility Model Content

[0004] The purpose of this invention is to provide a condenser and a dishwasher to solve the technical problem of poor air drying effect of existing condensers.

[0005] The condenser of this utility model can be achieved through the following technical solutions:

[0006] A condenser includes a condensation channel, an air inlet channel, an air outlet channel, and a fan. The condensation channel is provided with an air inlet, and the air outlet channel is provided with an air outlet. The condensation channel, the air inlet channel, and the air outlet channel are connected in sequence. The fan is located at the connection between the air inlet channel and the air outlet channel. A plurality of condensation plates are arranged at intervals in the condensation channel.

[0007] In one embodiment, several of the condenser plates are staggered, and a condensate return port is formed between two adjacent condenser plates.

[0008] In one embodiment, the condenser plate extends outward from the side wall of the condensation channel and is inclined toward the air inlet.

[0009] In one embodiment, the condensation channel is parallel to the air inlet channel, and the condensation channel and the air outlet channel form an L-shaped structure.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0025] Example 1

[0026] Please see Figure 1-5A condenser 10 is installed on the outer wall of the dishwasher's inner tub. The condenser 10 includes a condensation channel 11, an air inlet channel 12, an air outlet channel 13, and a fan 14. The condensation channel 11 has an air inlet 111. The condensation channel 11, air inlet channel 12, and air outlet channel 13 are sequentially connected. The fan 14 is located at the connection between the air inlet channel 12 and the air outlet channel 13. The air outlet channel 13 has an air outlet 131. Several condensing plates 112 are spaced apart within the condensation channel 11. The air inlet 111 is connected to the inner tub or a breather, allowing hot, humid steam to enter the condensation channel 11 from the air inlet 111. The hot, humid steam is cooled upon contact with the condensing plates 112, forming condensate. The condensate flows back from the air inlet 111 to the inner tub or breather. During this return flow, the condensate comes into contact with the steam at the air inlet 111, performing initial condensation of the hot, humid steam at the air inlet 111, thus significantly improving the steam condensation effect. After being cooled by the condensation channel 11, the steam is cooled and the water vapor is removed, turning it into low-temperature air. The low-temperature air is cooled again by passing through the air inlet channel 12 and the air outlet channel 13 in sequence, and finally becomes dry air without water vapor and is discharged to the outside of the dishwasher from the air outlet 131.

[0027] In this embodiment, the fan 14 draws the hot, humid steam from the inner liner into the condensation channel 11, which accelerates the discharge of steam from the inner liner and improves the drying efficiency of the tableware during the drying stage. The fan 14 is installed at the connection between the air inlet channel 12 and the air outlet channel 13, specifically: the air inlet end of the fan 14 is connected to the air outlet end 122 of the air inlet channel 12, and the air outlet end of the fan 14 is connected to the air inlet end of the air outlet channel 13. With this design, the air cooled by the condensation channel 11 is naturally cooled again during its passage through the air inlet channel 12, ensuring that the air in contact with the fan 14 is low-temperature and dry. This avoids the direct contact of high-temperature steam with the fan 14, preventing condensation and reducing the risk of the fan 14 malfunctioning and shutting down due to contact with condensate.

[0028] Please refer to 2-4. The condensation channel 11 is provided with a flow channel 114, and the air inlet 111 is located below the flow channel 114. Hot, humid steam flows into the flow channel 114 after passing through the air inlet 111. Several condensing plates 112 are staggered within the flow channel 114, forming a condensate return port 113 between adjacent condensing plates 112. The condensate collected on the condensing plates 112 flows out through the condensate return port 113 and finally exits from the air inlet 111. When the air inlet 111 is directly connected to the inner liner, the condensate flows back into the inner liner. When the air inlet 111 is connected to the respirator, the condensate flows back into the respirator.

[0029] Specifically, the condenser plate 112 extends outward from the side wall of the condensation channel 11, and is inclined towards the air inlet 111. It can be understood that one end of the condenser plate 112 is connected to the side wall of the condensation channel 11, and the other end of the condenser plate 112 has a gap with the side wall of the condensation channel 11. Because the condenser plates 112 are staggered, steam can only pass through the condensate return port 113 during the cooling process, increasing the contact area between the steam and the condenser plate 112, further improving the condensation effect. More specifically, in this embodiment, when the condenser 10 is vertically installed on the inner liner side wall, the condensate return port 113 is adjacent to the side wall of the condensation channel 11. It is understandable that the gap between one of the condensing plates 112 and the side wall of the condensing channel 11 is small, and the gap is adjacent to another condensing plate 112, so that the several condensate return ports 113 are also staggered, which extends the cooling path of the steam, ensures that the steam is fully cooled, and can better improve the condensation effect, so that the air entering the air inlet channel 12 has a low moisture content, ensuring that the air discharged from the air outlet 131 is dry air.

[0030] More specifically, the diameter of the air inlet 111 is D1, and the width of the flow channel 114 is W1, where D1 > W1. When the condenser is directly connected to the inner liner, the air inlet 111 is usually circular, and D1 refers to the inner diameter of the air inlet. When the condenser is connected to the breather, the air inlet can be rectangular to facilitate connection between the condenser and the breather, and D1 refers to the length of the longest side of the air inlet 111. The diameter of the air inlet 111 is greater than the width of the flow channel 114, which allows for rapid extraction of hot, humid steam into the flow channel 114, resulting in faster overall condensation efficiency and shorter exhaust time for the inner liner.

[0031] Please see Figure 3-4 The condenser 10 is generally L-shaped. The condensation channel 11 is parallel to the air inlet channel 12, and the condensation channel 11 and the air outlet channel 13 form an L-shaped structure, that is, there is an angle α between the condensation channel 11 and the air outlet channel 13, preferably 90°≤α≤135°. In this embodiment, the condensation channel 11 and the air outlet channel 13 are perpendicular, that is, the angle is 90°. The L-shape can make more reasonable use of the space on the inner wall of the liner and avoid the inability to install due to the condenser being too long. In addition, the L-shaped structure of the condenser can adjust the position of the air outlet 131 as needed, which can be directed towards the rear of the dishwasher or towards the front of the dishwasher.

[0032] Specifically, the air inlet channel 12 has an air inlet end 121 and an air outlet end 122. The air inlet end 121 is connected to the condensation channel 11. To prevent the low-temperature air entering the air inlet channel 12 from naturally cooling and generating a small amount of condensate, the air inlet channel 12 is provided with a liquid collection area 123, which is located at the lowest point of the air outlet end 121. Since the air temperature entering the air inlet channel 12 is low and the water vapor content is also low, the moisture in the liquid collection area 123 is also very small and can be naturally dried.

[0033] More specifically, the condenser 10 also has a mounting cavity 15, and the fan 14 is located inside the mounting cavity 15. The air outlet 122 is provided with a baffle 124, which is located at the edge of the mounting cavity 15, guiding the air discharged from the air outlet 122 to the air inlet of the fan 14. In this embodiment, the condensation channel 11 and the air inlet channel 12 are separated by a partition. The baffle 15 is connected to the partition and forms an angle, which is the liquid collection area 123, located at the lowest position. A small amount of condensate will not flow into the fan mounting cavity 15 through the port of the air outlet 122. The air outlet channel 13 is provided with a guide section 132, which is inclined towards the air outlet of the fan 14, so that the air outlet channel 13 can fit better with the fan 14.

[0034] Example 2

[0035] A dishwasher includes a breather 20 and a condenser 10 as described in Embodiment 1. The breather 20 is connected to the inner tub, and the condenser 10 is connected to the breather 20. The breather 20 has a breather port 21 and an air outlet 22. The breather port 21 is connected to the inner tub, and high-temperature, humid steam in the inner tub enters the interior of the breather 20 through the breather port 21. The air outlet 22 is connected to the air inlet 111. The steam, which has been initially condensed by the breather 20, overflows from the air outlet 22 and then enters the condensation channel 11 in the condenser through the air inlet 111. The condensate in the condensation channel 11 flows sequentially through the air inlet 11 and the air outlet 22, and then flows back into the breather 20.

[0036] Specifically, the condenser 10 has a protrusion 16 adjacent to the air outlet 131, and a groove (not shown in the figure) is provided at the air outlet 22. When the condenser 10 is connected to the breather 20, the protrusion 16 is embedded in the groove. That is, the condenser 10 is inserted into the breather 20, and the protrusion 16 is set on the outer wall of the condensation channel 11, so that after the two are installed together, the air inlet 111 is embedded in the air outlet 22, preventing steam from overflowing from the air outlet 22.

[0037] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
