AI Technical Summary
Existing dryers have low condensation efficiency in their condensers, and the small area on which water flows over the inner wall of the condenser leads to lint buildup that affects the condensation effect. Insufficient contact between the airflow and the water flow on the inner wall also prevents efficient condensation of water vapor in the humid air.
Design a condenser that employs a first spray assembly and a second spray assembly. The first spray assembly changes the water outlet direction through the reaction force of the sprayed water, while the second spray assembly increases the water mist coverage area through an atomizing plate and a conical cylinder, thereby increasing the contact area between the humid and hot air and the water.
It effectively removes lint from the inner wall of the condenser, increases the contact area between humid air and water, improves condensation efficiency, and achieves efficient drying of humid air.

The condenser 2 comprises a half shell 21, the half shell 21 is buckled on the outer surface of the side wall of the rear drum cover 1, the half shell 21 and part of the side wall of the rear drum cover 1 together constitute the shell of the condenser 2 and enclose a cavity 22 in the shell. The lower position of the part of the side wall of the rear drum cover 1 which constitutes the shell of the condenser 2 is formed with an air inlet 211 which communicates with the cavity 22, the air inlet 211 communicates with the inside of the clothes treatment drum, the air inlet 211 also serves as the drainage port of the condenser 2, the upper part of the half shell 21 is formed with an air outlet 212 which communicates with the cavity 22, the air outlet 212 is connected to the opening on the front drum cover through a circulating air duct (not shown in the figure) to communicate with the inside of the clothes treatment drum, a circulating fan and an electric heater downstream of the circulating fan are arranged in the circulating air duct. The upper part of the half shell 21 is provided with a first spraying assembly 3 and a second spraying assembly 4.
[0048] As shown in Figure 4 As shown, the first spray assembly 3 includes a first water inlet pipe 31 and a first spray member connected to the first water inlet pipe 31. The outlet end of the first water inlet pipe 31 extends downward from the outside of the half-shell 21 into the half-shell 21. The first water inlet pipe 31 is fixedly connected to the half-shell 21. The first spray member is a cylindrical spray arm 32 located inside the cavity 22. The spray arm 32 extends in a horizontal plane, and a connecting pipe 33 extends upward from the middle of the spray arm 32. The upper end of the connecting pipe 33 is inserted into the outlet end of the first water inlet pipe 31 and is coaxially and rotatably connected to the outlet end of the first water inlet pipe 31. Two first spray holes 321 and multiple second spray holes 322 are formed on the spray arm 32. One first spray hole 321 is located on the front side of the spray arm 32 (i.e., Figure 4 On the side facing outwards from the paper, near the right end, another first water spray hole 321 is located on the rear side of the spray arm 32 (i.e., on the side facing outwards from the paper). Figure 4 Located on the left side (towards the inside of the paper), the axis of the first water spray hole 321 is in a horizontal plane and perpendicular to the axis of the spray arm 32. Multiple second water spray holes 322 are evenly distributed on the outer circumferential surface of the spray arm 32. The diameter of the second water spray holes 322 is smaller than the diameter of the first water spray hole 321, and the second water spray holes 322 are used to atomize the sprayed water.
[0049] like Figure 4 and Figure 5 As shown, the second spray assembly 4 includes a second water inlet pipe 41, an atomizing plate 42, and a conical cylinder 43. The outlet end of the second water inlet pipe 41 extends into the cavity 22. The small end of the conical cylinder 43 is connected to the outlet end of the second water inlet pipe 41, and the large end of the conical cylinder 43 faces the middle region of the upper end of the cavity 22. The atomizing plate 42 is connected to the outlet end of the second water inlet pipe 41. A plurality of microholes 421 are formed on the atomizing plate 42, which penetrate along its thickness direction, so that the water in the second water inlet pipe 41 passes through the microholes 421 and forms a water mist.
[0050] When drying the laundry, the fan in the circulating air duct works, the hot and humid air in the laundry treatment cylinder enters the cavity 22 through the air inlet 211 and flows to the air outlet 212, the first water inlet pipe 31 supplies water to the spray arm 32, and the second water inlet pipe 41 supplies water to the atomizing plate 42. The water entering the spray arm 32 is sprayed out through the first water spray hole 321 and the second water spray hole 322. Under the action of the reaction force of the water flow sprayed out of the first water spray hole 321, the spray arm 32 rotates around its rotation shaft (i.e. the axis of the connecting pipe 33), and the water flow sprayed out of the first water spray hole 321 is sprayed onto the inner wall of the condenser 2 and flows downward along the inner wall of the condenser 2 under the action of gravity; the water sprayed out of the second water spray hole 322 forms water mist, and the water mist sprayed out of the second water spray hole 322 disperses in the cavity 22 and falls downward under the action of gravity while the spray arm 32 rotates. The water in the second water inlet pipe 41 becomes water mist after passing through the micro-holes 421 on the atomizing plate 42, and the water mist is guided by the conical cylinder 43 to the middle area of the upper end of the cavity 22 and falls downward under the action of gravity. The hot and humid air entering the cavity 22 contacts the water mist in the cavity 22 and the water flow on the inner wall of the condenser 2 during flowing to the air outlet 212, and the water vapor in the hot and humid air condenses into liquid water when meeting the low-temperature water mist and water flow, and the liquid water falls onto the inner wall of the condenser 2 to combine with the water flow, and finally the water flow enters the laundry treatment cylinder through the water outlet (i.e. the air inlet 211) of the condenser and is discharged through the drain hole 13, the hot and humid air becomes low-temperature dry air and flows from the air outlet 212 into the circulating air duct, the low-temperature dry air becomes high-temperature dry air after being heated by the electric heater and flows back to the laundry treatment cylinder along the circulating air duct, the laundry in the laundry treatment cylinder contacts the high-temperature dry air, and the water on the laundry evaporates into water vapor, thereby forming hot and humid air in the laundry treatment cylinder.
[0051] By the arrangement of the first spray assembly 3, water can be sprayed in different directions inside the shell of the condenser 2. This not only allows water to be sprayed to different positions of the inner wall of the shell of the condenser 2, increases the area of water flow on the inner wall of the shell of the condenser 2, effectively washes away the dust attached to the inner wall of the shell of the condenser 2, eliminates the influence of the attached dust on the condensing effect of the condenser 2, but also allows water to be sprayed into the cavity 22. The water in the cavity 22 falls downward, and the humid hot air entering the cavity 22 from the air inlet 211 at the lower part of the condenser 2 flows to the air outlet 212 at the upper part of the condenser 2. The water falling in the cavity 22 contacts the humid hot air flowing in the cavity 22, thereby further increasing the contact area of the humid hot air and the water for condensation, thereby improving the condensing efficiency of the condenser 2. The water mist sprayed through the second water spraying hole 322 of the spray arm 32 is uniformly dispersed in the cavity 22 of the condenser 2 while the spray arm 32 rotates. The water mist contacts the humid hot air flowing in the cavity 22 of the condenser 2, thereby further increasing the contact area of the humid hot air and the water for condensation, thereby more efficiently condensing the water vapor in the humid hot air into liquid water to dry the humid hot air. The plurality of second water spraying holes 322 are distributed on the outer peripheral surface of the spray arm 32, and the water mist sprayed through the second water spraying holes 322 has a larger spraying area, which can further increase the contact area of the humid hot air and the water for condensation, thereby improving the condensing efficiency of the condenser 2.
[0052] By the arrangement of the second spray assembly 4, the water mist sprayed into the cavity 22 of the condenser 2 is increased. The water mist contacts the humid hot air flowing in the cavity 22 of the condenser 2, thereby further increasing the contact area of the humid hot air and the water for condensation, thereby more efficiently condensing the water vapor in the humid hot air into liquid water to dry the humid hot air. The conical cylinder 43 of the second spray assembly 4 allows the water mist sprayed by the second spray assembly 4 to fall downward in the cavity 22 as much as possible, thereby reducing the situation that the water mist floats to the inner wall of the shell of the condenser 2, thereby improving the utilization rate of the water mist sprayed by the second spray assembly 4.
[0053] It should be noted that the large end of the conical cylinder 43 is directed to the middle region of the upper end of the cavity 22, which is only a specific arrangement, and in actual applications, it can be adjusted, such as the second spraying assembly 4 is arranged at the middle height of the half shell 21, the large end of the conical cylinder 43 is directed to the middle region of the middle height of the cavity 22, or the second spraying assembly 4 is arranged at other positions of the half shell 21, as long as it is higher than the air inlet 211, and the large end of the conical cylinder 43 is directed to the middle region of the corresponding position of the cavity 22. In addition, the second spraying assembly 4 includes the above-mentioned conical cylinder 43, which is only a more preferred arrangement, and in actual applications, it can be adjusted, such as in a feasible embodiment, the second spraying assembly 4 does not include the above-mentioned conical cylinder 43. In addition, the second spraying assembly 4 is arranged on the shell of the condenser 2, which is also a more preferred arrangement, and in actual applications, it can be adjusted, such as in a feasible embodiment, the above-mentioned second spraying assembly 4 is not arranged.

In addition, the plurality of second water spraying holes 322 are formed on the spraying arm 32, which is also a more preferred arrangement, and in actual applications, it can be adjusted, such as in a feasible embodiment, only the above-mentioned first water spraying hole 321 is formed on the spraying arm 32 without forming the above-mentioned second water spraying hole 322. In addition, two first water spraying holes 321 are formed on the spraying arm 32, one first water spraying hole 321 is located on the front side (i.e. Figure 4 the side facing out of the paper) of the spraying arm 32 near the right end, and the other first water spraying hole 321 is located on the back side (i.e. Figure 4The first water spraying hole 321 is formed at a position close to the left end of the spraying arm 32, which is only a specific arrangement, and in actual application, it can be adjusted, for example, in one possible embodiment, the spraying arm 32 only forms the above-mentioned first water spraying hole 321; in another possible embodiment, the axis of the above-mentioned first water spraying hole is perpendicular to the axis of the spraying arm 32 and forms an angle of 30° with the horizontal plane, and the axis of the first water spraying hole can also be arranged in other directions, as long as it is neither intersected nor parallel to the rotation axis of the spraying arm 32. In addition, the middle part of the spraying arm 32 extends upwardly to form a connecting pipe 33, the upper end of the connecting pipe 33 is inserted into the water outlet end of the first water inlet pipe 31 and is rotatably connected coaxially with the water outlet end of the first water inlet pipe 31, which is also a specific arrangement, and in actual application, it can be adjusted, for example, the first end of the spraying arm is rotatably connected with the water outlet end of the first water inlet pipe 31, the axis of the spraying arm is perpendicular to the axis of the first water inlet pipe 31, and the first water spraying hole is formed at a position close to the second end of one side of the spraying arm, and the axis of the first water spraying hole is neither intersected nor parallel to the rotation axis of the spraying arm.
