Description

Embodiments of the present invention relate to clothes dryers.

2. Description of the Related Art A drum-type washer/dryer, which is an example of a clothes dryer for drying clothes, includes a water tank as a drying chamber in which clothes are stored, and a circulation air passage for circulating air in the water tank. In addition, an evaporator that constitutes a well-known heat pump mechanism for drying is arranged as a dehumidifying section in this circulation air passage. In the drying process of drying the clothes, the air in the water tank is circulated through the circulation air passage. The air flowing through the air circulation path contains foreign matter such as lint and dust. Therefore, in the middle of the air circulation path, a drying filter is provided on the windward side of the dehumidifying section to capture the foreign matter.

By the way, by reducing the mesh size of the dry filter, it is possible to improve the ability to trap foreign matter. However, the smaller the mesh size of the dry filter, the greater the resistance of the air passage due to the dry filter, making it impossible to secure a sufficient circulating air volume. Therefore, there is a limit to reducing the mesh size of the dry filter. Therefore, the dry filter cannot capture all the foreign matter, and it is impossible to completely prevent the foreign matter from passing through the dry filter. Have difficulty. After passing through the dry filter, the foreign matter further flows downwind in the circulation air passage and reaches the dehumidifying section. Therefore, in a washing/drying machine equipped with a heat pump mechanism for drying, there is a problem that foreign matter that has passed through the drying filter accumulates on the windward side of the dehumidifying section after long-term use.

In order to solve such problems, conventionally, the development of techniques for removing foreign matter deposited on the windward side of the dehumidifying section has been studied. For example, Patent Literature 1 discloses a configuration in which water is discharged to the windward side of a dehumidifying section to remove foreign matter accumulated in the section.

In the conventional configuration, the cleaning device that discharges water to the windward side of the dehumidifying section has an elongated shape along the windward side end surface of the dehumidifying section, and the discharge port that discharges water extends along the longitudinal direction of the device. It has an arranged structure. In addition, the cleaning device in the conventional configuration has a water supply port to which water is supplied at one end in the longitudinal direction of the device. In the conventional cleaning apparatus constructed in this way, if the force of the water supplied from the water supply port is too strong, the water passes through the discharge port on the water supply port side, and the water flows out from the discharge port on the water supply port side. Discharge becomes difficult. Therefore, there is a concern that the portion of the windward side end face of the dehumidifying section on the side of the water inlet may be insufficiently cleaned.

Therefore, the present embodiment provides a clothes dryer having a washing function by discharging water to the dehumidifying section, and provides a configuration that enables water to be discharged as evenly as possible to the dehumidifying section.

The first wall portion 153 configured in this manner weakens the force of water supplied from the water supply port 101 into the water inlet portion 152 . Then, the water weakened by the first wall portion 153 flows toward the washing device main body portion 151 through the gap S1.

The cleaning device 100 also has a second wall portion 154 inside. The second wall portion 154 is an example of a second water weakening portion, and is provided between the first wall portion 153 and the plurality of discharge ports 140 in this case. In this case, the second wall portion 154 extends in a direction substantially or completely orthogonal to the longitudinal direction A1, in other words, in a direction substantially or completely along the airflow direction A2. Also, the second wall portion 154 forms a gap S2 having a predetermined size with the first wall portion 153 . Further, the second wall portion 154 is provided so as to face the gap S1 described above. The second wall portion 154 configured in this manner further weakens the momentum of the water flowing from the inside of the water inlet portion 152 toward the washing device main body portion 151 through the gap S1.

Also, the intervals between the plurality of recesses 155 may all be the same interval, or may be different intervals. When the intervals between the plurality of recesses 155 are different, the intervals between the recesses 155 are shortened on the side of the water supply port 101 where water easily passes, and the intervals between the recesses 155 are shortened on the side opposite to the water supply port 101 where water does not easily pass. A configuration such as lengthening can be adopted.

Further, the inflow promoting portion is not limited to the configuration in which the upper portion of the upper wall portion 123 is cut away, and may be a hole or a slit penetrating through the upper wall portion 123, for example. That is, various configurations can be applied to the inflow promoting section as long as it is configured to promote the inflow of water from the upstream space 131 into the downstream space 132 .

Further, the position of the water supply port 101 in the washing device 100 can be changed as appropriate. In this case, depending on the position of the water supply port 101 in the cleaning device 100, the positions, extending directions, lengths, etc. of the first wall portion 153, the second wall portion 154, and the upper wall portion 123 are appropriately adjusted to achieve the above-described It is possible to obtain the same effect as the embodiment described above.

In addition to the first wall portion 153 and the second wall portion 154, the cleaning device 100 may further include one or more walls, that is, walls capable of weakening the momentum of the water. .

Further, the end surface of the upper wall portion 123 in the longitudinal direction A1 of the washing device 100, the end surface on the side opposite to the water supply port 101 may be in contact with the inner surface of the upper recessed portion 112a. That is, the upstream space 131 and the downstream space 132 do not communicate with each other on the side opposite to the water supply port 101 among both sides of the upper wall 123 in the longitudinal direction A1 of the cleaning device 100. may be configured.

Further, the configuration of the discharge port 140 can be changed as appropriate. For example, the diameter and length of the inlet portion 141 and the outlet portion 142 can be changed as appropriate. In addition, the outlet portion 142 of the discharge port 140 may be tapered such that the diameter increases downward. According to this configuration example, the water discharged from the discharge port 140 can be spread more easily.

In addition, the ejection port 140 may have a uniform diameter as a whole. That is, the ejection port 140 may be configured without the outlet portion 142 . Also with this configuration example, it is possible to spread and discharge water by the force of the water flowing through the inlet 141, for example.

Also, the number of discharge ports 140 provided in the cleaning device 100 can be changed as appropriate. Moreover, the discharge port 140 is not limited to a cylindrical tubular structure, and various structures can be applied as long as it has a through-hole structure capable of discharging water.
