Technical field

The invention relates to the technical field of laundry and drying equipment, and in particular to a condensing device and a laundry washing and drying machine therewith.

Background technique

With the improvement of living standards, people's requirements for washing and drying clothes have also increased. At present, the washing and drying machine on the market has low drying efficiency, and it takes a long time to dry the clothes, and a large amount of wire scraps and impurities are not discharged with the condensed water during the drying process, and are attached to the clothes on the one hand. Allergic skin damage; on the other hand, the wire impurities adhere to the condenser and the dryer, causing the blockage to affect the drying efficiency.

At present, the drying machine on the market is connected to the outer cylinder by a drying fan and a condenser, which is enough to form a recyclable system. The drying fan is heated to form steam in the cylinder, and the steam is liquefied with cooling water. Take the moisture from the clothes while taking away the lint and impurities in the steam.

In the structure of the existing condenser, the cooling water is smoothly drained along the outer wall of the condenser to the air inlet of the condenser, the water flow is gentle, the cooling water participating in the heat exchange is limited, and the heat exchange efficiency between the steam and the cooling water is poor, resulting in poor condensation efficiency. Thereby the drying efficiency is poor. Moreover, the poor condensing efficiency also causes the steam to enter the condenser without sufficient condensation. The scraps and impurities in the steam enter the condenser and the drying fan, and accumulate at the condenser outlet and the dryer, thereby further affecting the drying. Dry efficiency.

Washing machines, as a kind of household appliances, have gradually become an indispensable part of people's lives. With the improvement of living standards, the rapid laundry can no longer meet people's daily needs. Sometimes people also require clothes to be worn in the shortest time after washing, so the dryer is also a kind of drying equipment. The more you walk into people's homes.

However, if a washing machine and a clothes dryer are placed in the home, not only does it occupy a large space, but also people need to transfer the clothes washed in the washing machine to the clothes dryer, because the capacity of the clothes dryer is generally smaller. The capacity of the washing machine, so the laundry that is washed once can not be processed once in the dryer, and needs to be divided into two or even multiple times. In addition, there is now a drum washing machine having a drying function, but the washing machine is generally limited in capacity due to the need for drying, and the entire washing and drying process takes a long time.

The combined washing and drying machine of the utility model combines a well-known washing machine and a clothes dryer to manufacture materials, which can save manufacturing materials and reduce manufacturing cost. Because of combined manufacturing, the floor space occupied by the use is small, because the clothes dryer is in the upper position. It is easy to use because it forms a working height.

The above utility model patent combines a clothes dryer and a washing machine to solve the problem of simultaneous laundry and drying, but due to the different working processes of the washing machine and the dryer, the two are not integrated, resulting in both resources. waste.

The top end of 102 is gently sloped and extends to the air inlet 103. The top end portion of the projection 102 protrudes toward the inside of the condensation duct 101, and a retracting structure for accelerating the flow of the steam 105 is formed in the condensation duct 101.

In the above arrangement, by the arrangement of the structure of the protrusion 102, a retracting structure for accelerating the flow of the steam 105 is formed in the condensing duct 101, so that the steam 105 enters the condensing duct 101 of the condensing device, and the flow path is narrowed and the flow rate is narrowed. The speed is increased, thereby accelerating the heat exchange efficiency of the steam 105 and the cooling air, so that the efficiency of converting the steam 105 into the condensed water 104 is further improved, and the efficiency of the steam 105 converted into the condensed water 104 is increased while being attached to the steam 105.

In another solution, the protrusion 102 is configured to have a non-smooth transition with the inner wall of the condensing duct 101, and the protrusion 102 has a small angle with the inner wall of the adjacent upstream condensing duct 101, such as 90- At 1011020 degrees, the water velocity of the condensed water 104 flowing down from the upstream is higher at this time, so that after the collision with the protrusion 102, the movement speed changes greatly, and almost appears to condense in a direction perpendicular to the flow direction.
