Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of washing machines, and particularly relates to a washing machine with a drying function. BACKGROUND

[0002] At present, the common full-automatic washing machine generally only has the washing, rinsing and dehydration functions. After the washing process ends, the air inside and outside the washing tub is still humid. After being used for a long time, mildew will breed in the washing tub. In humid areas, clothes are not easy to dry after washing. If the clothes are not dried for a long time, mildew will breed, which is harmful to human health. With the improvement of people's living standards and the improvement of health and environmental protection awareness, the washing machines newly developed for the above problems have the functions of drying the washing tub and drying clothes. The humidity in the tub is eliminated by the natural wind sucked by the high-speed rotation of the inner tub of the washing machine, and the clothes are dried. The clothes dried have a low water content, which can reduce the drying time, reduce the contact between the clothes and the dust in the air, and reduce secondary pollution.

[0003] At present, the washing machine with the drying program only simply increases the dehydration time, but does not set a special exhaust structure, so that the speed of gas flow is slow, resulting in low drying efficiency. Moreover, a common problem is that in the case of long-time dehydration, the motor works continuously for a long time, and the load is heavy, which can cause the temperature of the motor winding to rise, the heat generation is large, and the service life of the motor is affected. Moreover, the motor keeps running during the drying process, which also consumes a large amount of power.

[0004] In addition, in the case of high-speed rotation of the inner tub, the gas in the outer tub flows upward and mostly flows out through the inlet on the control disc seat, but a part of it will flow into the cavity of the lower opening of the control disc seat, condense in the cavity, and possibly cause damage to the electrical components in the cavity.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] Referring to Figures 1-6 It is the first embodiment of a laundry dryer with drying function provided by the present application, a laundry dryer 100 with drying function comprises: a box body 10, a control disc seat 20, an upper cover 30, the control disc seat 20 is located at the top of the box body 10, and the upper cover 30 is hingedly arranged on the control disc seat 20; further comprising an outer barrel and an inner barrel located in the box body 10, the outer barrel and the inner barrel are arranged in a sleeve structure, and the outer barrel is hung in the box body 10 through a hanger; the middle part of the control disc seat 20 is a clothes feeding port 21, and the clothes feeding port 21 is located above the upper opening of the inner barrel.

[0050] The drying acceleration structure is arranged on the upper cover 30, which is used to accelerate the flow of gas during the drying process of the laundry dryer; by arranging the drying acceleration structure, it is beneficial to increase the speed of the gas flowing out of the laundry dryer, and it is beneficial to improve the drying efficiency.

[0051] Specifically, the drying acceleration structure has a first air outlet 311 arranged on the upper cover 30, a drainage cap 312 arranged above the first air outlet 311 for drainage, and a plurality of second air outlets 313 arranged on the upper cover 30, the second air outlets 313 are located in the direction of the gas flow after being drained by the drainage cap 312. When the inner barrel of the laundry dryer rotates at high speed, the rotating gas flow in the outer barrel flows upward, the gas in the outer barrel flows out at high speed from the clothes feeding port 21 upward, and then flows out from the first air outlet 311 on the upper cover 30, and then changes direction after being drained by the drainage cap 312, the gas flows at high speed along the upper end surface of the upper cover 30, that is, the gas flows at high speed from above the second air outlet 313, so that a negative pressure is formed at the second air outlet 313; it is beneficial for the gas to flow out of the laundry dryer through the second air outlet 313. And when the inner barrel rotates at high speed, the rotating gas flow in the outer barrel also pushes the gas below the upper cover 30 to flow upward from the second air outlet 313.

[0052] Referring to Figure 5As shown, when the inner drum of the washing machine rotates at high speed, the rotating air flow in the outer drum converges upward and to the middle part, and therefore the first air outlet 311 is arranged at the middle part of the upper cover 30, so that the high-speed air flow flows out upward from the first air outlet 311, and forms the high-speed flow deflected air flow after being deflected by the deflection cap 312, the deflected air flow flows along the upper end surface of the upper cover 30, that is, the deflected air flow flows above the second air outlet 313, so that the negative pressure is formed above the second air outlet 313, which is beneficial to sucking the air below the second air outlet 313 upward; and the high-speed air flow in the middle part of the rotating air flow in the outer drum mainly flows out from the first air outlet 311, and the low-speed air flow outside the high-speed air flow also flows upward, and flows out through the second air outlet 313 under the suction of the negative pressure above the second air outlet 313. The high-speed air flow flowing out from the first air outlet 311 is used in the application, and the high-speed air flow flows above the second air outlet 313 after being deflected by the deflection cap 312, so that the negative pressure is formed at the second air outlet 313, and then the air in the washing machine is promoted to flow out from the second air outlet 313.

[0055] In the embodiment, in the direction of the air flow deflected by the deflection cap 312, the size of the deflection cap 312 is smaller than the size of the first air outlet 311, or the size of the deflection cap 312 projected on the first air outlet 311 is smaller than the size of the first air outlet 311, that is, the deflection cap 312 does not completely cover the first air outlet 311, and part of the high-speed air flow flowing upward after flowing through the first air outlet 311 is deflected by the deflection cap 312 to form the deflected air flow; and part of the air flow directly flows out upward, which is referred to as direct flow air flow. That is, the high-speed air flow flowing through the first air outlet 311 is divided into two parts, which is beneficial to promote the air to flow out through the second air outlet 313, and is also beneficial to ensure the air flow through the first air outlet 311.

[0056] In other embodiments, the size of the deflection cap 312 projected on the first air outlet 311 can be equal to or greater than the size of the first air outlet 311.

The two sides of the first air outlet 311 are in the width direction of the first air outlet 311.

[0058] Preferably, the two drainage plates 3121 are close to each other and connected in the upward direction, and by setting the downward inclination of the drainage plate 3121 in the flow direction of the diverted airflow, it is beneficial to make the diverted airflow after flowing through the drainage plate 3121 flow close to the upper end surface of the upper cover 30, so that the negative pressure at the second air outlet 313 is larger.

[0059] In other embodiments, the two drainage plates 3121 can also be arranged perpendicular to the first air outlet 311.

[0061] In the embodiment, the second air outlet 313 is a long strip, and the second air outlet 313 is arranged parallel to the first air outlet 311.

[0062] In other embodiments, the second air outlet 313 can also be arranged as a long strip, and the second air outlet 313 is arranged perpendicular to the first air outlet 311. Or the second air outlet 313 is circular, and a plurality of second air outlets 313 are arranged on both sides of the first air outlet 311.

[0063] In the embodiment, the control disc seat 20 has a clothes throwing opening 21 and a lower open cavity. In order to avoid the humid airflow in the outer barrel from condensing in the cavity, a ventilation hole 22 for gas outflow in the cavity is arranged on the control disc seat 20, so that the gas in the cavity can flow outward from the ventilation hole 22.

[0064] In the embodiment, a plurality of ventilation holes 22 are arranged on the left and right side walls of the control disc seat 20. In other embodiments, the ventilation hole 22 can also be arranged at other positions of the control disc seat 20.

[0065] Referring to Figures 1-2 、 Figures 7-8 , the second embodiment of the laundry washing machine with air-drying function is provided, and the main difference between the second embodiment and the first embodiment is that the specific structure of the air-drying acceleration structure is different, and other structures can be the same as those of the first embodiment.

[0066] The laundry washing machine 100 with air-drying function comprises a cabinet 10, a control disc seat 20, and an upper cover 30, the control disc seat 20 is located at the top of the cabinet 10, and the upper cover 30 is hingedly arranged on the control disc seat 20; further comprising an outer drum and an inner drum located in the cabinet 10, the outer drum and the inner drum are arranged in a sleeve manner, and the outer drum is hung in the cabinet 10 through a hanger; the middle part of the control disc seat 20 is a laundry throwing opening 21, and the laundry throwing opening 21 is located above the upper opening of the inner drum.

When the inner drum of the laundry washing machine rotates at a high speed, the rotating gas flow in the outer drum flows upwards, the gas in the outer drum flows out at a high speed from the laundry throwing opening 21, and then flows out from the first air outlet 311 of the upper cover 30, and then changes direction after being guided by the flow guide cap 312, and the gas flows at a high speed along the upper end surface of the upper cover 30, that is, the gas flows at a high speed from above the second air outlet 313, so that a negative pressure is formed at the second air outlet 313; the gas in the laundry washing machine is beneficial to flow out upwards through the second air outlet 313. And when the inner drum rotates at a high speed, the rotating gas flow in the outer drum also pushes the gas below the upper cover 30 to flow upwards from the second air outlet 313.

[0069] When the inner tub of the washing machine rotates at high speed, the rotating air flow in the outer tub converges upward and to the middle part, and therefore the first air outlet 311 is arranged at the middle part of the upper cover 30, so that the high-speed air flow flows out upward from the first air outlet 311, and forms the high-speed flow deflected air flow after being deflected by the deflection cap 312, the deflected air flow flows along the upper end surface of the upper cover 30, that is, the deflected air flow flows above the second air outlet 313, so that the negative pressure is formed above the second air outlet 313, which is beneficial to the air below the second air outlet 313 being sucked upward, and the low-speed air flow outside the high-speed air flow in the rotating air flow in the outer tub also flows upward and flows out through the second air outlet 313 under the suction of the negative pressure above the second air outlet 313. The high-speed air flow flowing out from the first air outlet 311 is utilized in the application, the high-speed air flow flows above the second air outlet 313 after being deflected by the deflection cap 312, so that the negative pressure is formed at the second air outlet 313, and then the air in the washing machine is promoted to flow out from the second air outlet 313.

[0070] In the embodiment, when the inner tub of the washing machine rotates at high speed, the rotating air flow in the outer tub converges upward and to the middle part, and the first air outlet 311 is a circular hole arranged at the middle part of the upper cover 30, so that the high-speed air flow flowing upward from the laundry throwing opening 21 passes through the circular first air outlet 311, and the first air outlet 311 is filled with the high-speed air flow, which is beneficial to improving the discharge amount and discharge speed of the high-speed air flow and improving the drying efficiency.

[0072] Preferably, the deflection cap 312 has a tapered plate 3123 which is narrow at the top and wide at the bottom, and is arranged downwardly inclined in the flow direction of the deflected air flow, which is beneficial to making the deflected air flow flow close to the upper end surface of the upper cover 30 after passing through the tapered plate, so that the negative pressure at the second air outlet 313 is larger.

[0073] In other embodiments, the deflection cap 312 can be arranged in a herringbone deflection plate structure similar to the first embodiment, so that the deflected air flow flows in two directions.

[0074] In the embodiment, the second air outlet 313 is an arc-shaped opening coaxially arranged with the first air outlet 311, so that the area of the second air outlet 313 is larger in the direction close to the second air outlet 313, and the speed of the deflected air flow gradually decreases in the direction away from the first air outlet 311, and therefore the second air outlet 313 is arranged as an arc-shaped opening, which is beneficial to improving the air volume flowing through the second air outlet 313.

[0075] In other embodiments, the second air outlet 313 is long strip-shaped, and a plurality of second air outlets 313 are arranged radially in the circumference of the first air outlet 311. Alternatively, the second air outlet 313 is a circular hole arranged in the circumference of the first air outlet 311.
