  • a washing machine including an inner tub, an outer tub and a drying assembly.
  • a condensation cavity is formed between a rear wall of the inner tub and a rear wall of the outer tub.
  • the drying assembly includes a heating air duct, and a fan and a heating device that are disposed in the heating air duct.

  • a position, proximate to the air outlet of the condensation cavity, of an inner side face of the rear wall of the outer tub is recessed in a direction away from the inner tub to form an enlarged cavity.
  • an enlarged cavity recessed in the direction away from the inner tub is formed at the inner side face of the rear wall of the outer tub.
  • the enlarged cavity enlarges a sectional area of the condensation cavity proximate to the air outlet of the condensation cavity, and reduces airflow resistance of this portion of the condensation cavity.
  • the moist air may easily enter the condensation cavity for condensation process, which reduces the amount of moist air without condensation process that escapes from dehydration holes in the side wall of the inner tub to an inner surface of the rear wall of the outer tub, and thus improves a condensing efficiency.
  • orientations or positional relationships indicated by terms “center”, “upper”, “lower”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, etc. are based on orientations or positional relationships shown in the drawings, which is merely to facilitate and simplify the description of the present application, but not to indicate or imply that the referred devices or elements must have a particular orientation, or must be constructed or operated in a particular orientation. Therefore, these terms should not be construed as limitations to the present application.
  • a conventional washing machine with a drying function e.g., a washing machine disclosed in the prior art 1, as shown in FIG. 1 , mainly includes a machine body 01, a tub 02 and a drying assembly.
  • the drying assembly is mainly composed of a drying duct 03, a fan motor 04, a heater 05, and a condenser structure 06.
  • An air outlet of the drying duct 03 is communicated with a front opening portion of the tub 02, an air suction port of the drying duct 03 is connected to the condenser structure 06, and the other end of the condenser structure 06 is communicated with a rear of the tub 02, so that the tub 02 and the drying assembly form a circulating air path, and the circulating air path is powered by the fan motor 04.
  • Air is heated by the heater 05 and is blown into an interior of the tub 02, and the hot air takes away moisture in the laundry after coming in contact with the laundry in a drum, thereby drying the laundry in the tub 02.
  • the hot air takes away moisture in the laundry and converts into moist air, and the moist air is condensed and cooled by the condenser structure 06 to separate air from water in the moist air; and then the air enters the circulating air path to continue to participate in the drying process, and the water is discharged.
  • the prior art CN103797174B discloses a laundry treating machine.
  • the laundry treating machine may include a tub, a drum, an air supply device, a lint filter, a filter cleaning device, and a cooling water supply device.
  • the cooling water supply device supplies cooling water to an inner rear surface of the tub, so that the moist air in the circulating air path is condensed on the inner rear surface of the tub. That is, the inner rear surface of the tub is a condensation region.
  • the hot air After the hot air provided by the air supply device comes in contact with the laundry in the drum, the hot air takes away the moisture in the laundry and becomes moist air. There are two paths for the moist air to leave. One path is that the moist air passes through dehydration holes in a rear wall of the drum and reaches the inner rear surface of the tub, and this part of moist air is able to come in contact with condensed water on the inner rear surface of the tub to separate the air from the water, and dried air is sucked by the air supply device and enters the drum again.
  • the other path is that the moist air passes through dehydration holes in a side wall of the drum and reaches an inner side surface of the tub, this part of moist air is basically not condensed, but is sucked by the air supply device and enters the drum again. That is, the moist air frequently enters the drum to come in contact with the laundry in the drum.
  • the moist air coming out of the dehydration holes in the side wall of the drum occupies most of moist air, which causes problems of long drying time and poor drying effect.
  • Embodiments of the present application provide a washing machine, referring to FIG. 2 , including an inner tub 100, an outer tub 200 and a drying assembly 300.
  • a condensation cavity 400 is formed between a rear wall 110 of the inner tub and a rear wall 210 of the outer tub.
  • the drying assembly 300 includes a heating air duct 310, and a fan 320 and a heating device 330 that are disposed in the heating air duct 310.
  • One end of the heating air duct 310 is communicated with an air outlet 410 of the condensation cavity, and the other end of the heating air duct 310 is communicated with an air inlet 120 of the inner tub.
  • the fan 320 pumps air in the inner tub 100 into the condensation cavity 400 for condensation, guides the air into the heating air duct 310 to be heated by the heating device 330, and then pumps the air into the inner tub 100 to form circulation, so as to dry the laundry.
  • a position, proximate to the air outlet 410 of the condensation cavity, on an inner side face of the rear wall 210 of the outer tub is recessed in a direction away from the inner tub 100 to form an enlarged cavity 220.
  • the enlarged cavity 220 recessed in the direction away from the inner tub 100 is formed at the inner side face of the rear wall 210 of the outer tub.
  • the enlarged cavity 220 enlarges a sectional area of a portion of the condensation cavity 400 proximate to the air outlet 410 of the condensation cavity, and reduces airflow resistance of this portion of the condensation cavity 400.
  • the moist air may easily enter the condensation cavity 400 for condensation process, which reduces the amount of moist air without condensation process that escapes from dehydration holes in a side wall 130 of the inner tub to a side wall 230 of the outer tub, and thus improves the condensation efficiency.
  • the moist air entering the condensation cavity 400 performs a heat exchange with the condensed water. After condensation process, air and water in the moist air may be well separated, and the dried air continues to enter the heating air duct 310 to be heated by the heating device 330, and then is pumped into the inner tub 100 to form circulation. In this way, the drying time is shortened and the drying effect is enhanced.
  • the inner tub 100 is a core component for laundry in the washing machine, and is in motion for a long time.
  • the inner tub 100 is formed by connecting the rear wall 110 of the inner tub (i.e., a rear flange of the inner tub 100) and the side wall 130 of the inner tub (i.e., a rim of the inner tub 100).
  • a flanging edge 140 is inevitably formed around the rear of the inner tub 100.
  • the existing flanging edge 140 reduces a gap between this portion of the inner tub 100 and the outer tub 200, i.e., reduces a sectional area of this portion of the condensation cavity 400, thereby increasing airflow resistance to the moist air entering the condensation cavity 400. Since the air flows more easily in a direction with low resistance, the moist air is more likely to flow out through the dehydration holes in the side wall 130 of the inner tub to the side wall 230 of the outer tub. That is, the moist air basically fails to be subjected to the condensation process, and then enters the heating air duct 310 through the air outlet 410 of the condensation cavity.
  • the air outlet 410 of the condensation cavity is located on an upper side of the flanging edge 140, and a partial region of the air outlet 410 is located in a region above a region between the flanging edge 140 and the rear wall 210 of the outer tub.
  • the condensation effect of moist air is directly affected. Moist air that is not subjected to condensation process repeatedly enters circulating air to come in contact with the laundry in the inner tub 100, which causes the problems of long drying time and poor drying effect.
  • the enlarged cavity 220 is provided at a position corresponding to the flanging edge 140, that is, the sectional area of this portion of the condensation cavity 400 is enlarged. As a result, the airflow resistance to the moist air entering the condensation cavity 400 is reduced to promote the moist air to enter the condensation cavity 400, which is conductive to improving the condensation efficiency, shortening the drying time and enhancing the drying effect.
  • Forming the enlarged cavity 220 through the rear wall 210 of the outer tub may be implemented in a variety of manners.
  • an overall thickness of the rear wall 210 of the outer tub may be kept unchanged, and the rear wall 210 of the outer tub locally protrudes outwards to form the enlarged cavity 220.
  • a space may be vacated by shortening the reinforcing ribs 240 to form the enlarged cavity 220.
  • the enlarged cavity 220 of such an implementation makes full use of a space of the machine body occupied by part of the original reinforcing ribs 240 on the outside of the rear wall 210 of the outer tub. Therefore, dimensions of the machine body are not increased.
  • a volume of the enlarged cavity 220 by recessing the rear wall 110 of the inner tub towards an inside of the inner tub 100 at a position proximate to the flanging edge 140.
  • the sectional area of this portion of the condensation cavity 400 is increased, and the airflow resistance to the moist air entering the condensation cavity 400 is reduced, thereby improving the condensation effect, and finally enhancing the drying effect.
  • a temperature inside the outer tub 200 gradually rises.
  • An inner surface 211 of the rear wall of the outer tub is a region where the condensation process mainly occurs.
  • a spray device 500 is provided in the condensation cavity 400, and the spray device 500 includes a spray head 510.
  • the spray head 510 is disposed on the top of the rear wall 210 of the outer tub, and the spray head 510 sprays condensed water onto the inner surface 211 of the rear wall of the outer tub.
  • the spray head 510 is located on the top, so that the condensed water may be fully dispersed on the inner surface 211 of the rear wall of the outer tub from top to bottom as much as possible. In this way, the contact area between the moist air and the condensed water is increased, and further the condensation efficiency is improved.
  • the spray head 510 sprays the condensed water to the top of the rear wall 210 of the outer tub.
  • the condensed water is used in a main region for condensation process, which may improve the condensation efficiency while saving water; and on the other hand, if the condensed water is sprayed randomly, the condensed water may be sprayed on the rear wall 110 of the inner tub, which may prevent the moist air from passing through the dehydration holes in the rear wall 110 of the inner tub. That is, the amount of moist air that reaches the condensation cavity 400 for condensation process is reduced, thereby weakening the condensation effect, and further affecting the drying time and the drying effect.
  • the current technological production level is relatively developed, and the spray head 510 may be integrally formed with the rear wall 210 of the outer tub.
  • the spray head 510 may be integrally formed with the rear wall 210 of the outer tub.
  • the number of water outlets 511 of the condensed water spray head may be set to two, specifically, a water outlet 511a of the spray head and a water outlet 511b of the spray head.
  • the water outlet 511a of the spray head and the water outlet 511b of the spray head have opposite water outlet directions, and both spray condensed water tightly against the inner surface 211 of the rear wall of the outer tub along a direction parallel to the rear wall 210 of the outer tub.
  • the water outlet 511a of the spray head and the water outlet 511b of the spray head have the opposite water outlet directions, so that distribution of the condensed water on the inner surface 211 of the rear wall of the outer tub may be better taken into account comprehensively; in addition, the spray head 510 sprays the condensed water tightly against the inner surface 211 of the rear wall of the outer tub along the direction parallel to the rear wall 210 of the outer tub, which may reduce the amount of condensed water splashed into a region in the condensation cavity 400 except for the inner surface 211 of the rear wall of the outer tub, thereby improving the condensation efficiency while avoiding water waste.
  • the outer tub 200 includes an outer tub front cover 250 and an outer tub rear cover 260.
  • the inner tub 100 may be first assembled to the outer tub rear cover 260 through a bearing, and then the outer tub front cover 250 is connected to the outer tub rear cover; in addition, a sealing ring is provided at a joint between the outer tub front cover 250 and the outer tub rear cover 260. In this way, it may be ensured that the outer tub 200 has a good sealing performance and is not likely to leak water and air.
  • small impurities such as lint and flocks may be produced from the laundry. These small impurities are easily sucked into the heating air duct 310, and then are attached to fan blades of the fan 320 and heating pipes of the heating device 330. If the fan blades absorb too many impurities, performance reduction or even failure of the fan 320 is caused, thereby affecting the drying efficiency; and if too many impurities are adhered to the heating pipes, a scorching smell or even a hidden danger of fire is easily caused. Therefore, if these impurities are not removed in time, a service life of the product may be shortened, and even potential safety hazards are brought to users. In order to reduce the occurrence of the above situation, referring to FIG.
  • the air outlet 410 of the condensation cavity is provided in the side wall 230 of the outer tub.
  • the air outlet 410 of the condensation cavity and the side wall 230 of the outer tub are integrally formed.
  • a filter screen 600 is provided in the air outlet 410 of the condensation cavity, and the filter screen 600 may filter small impurities such as lint to prevent excessive lint from attaching to the heating air duct 310 to block the heating air duct 310, thereby increasing the circulation efficiency.
  • the filter screen 600 may be implemented in a variety of manners.
  • the filter screen 600 may be integrally formed with the side wall 230 of the outer tub.
  • the filter screen 600 and the side wall 230 of the outer tub are integrally formed, which may increase a strength of the thinned portion of the rear wall 210 of the outer tub to prevent the rear wall 210 of the outer tub from being locally deformed.
  • the filter screen 600 may also be produced separately and then installed in the air outlet 410 of the condensation cavity, and this implementation has an advantage of low requirements on a production process.
  • a filter screen cleaning spray head 700 may be provided at the filter screen 600, and the filter screen cleaning spray head 700 is used for washing the filter screen 600.
  • the air outlet 410 of the condensation cavity is generally disposed at a position slightly lower than the top of the outer side wall of the outer tub 200 in actual situations, that is, the air outlet 410 of the condensation cavity is slightly inclined downwards.
  • the filter screen 600 also has a downward inclined angle, and thus the filter screen cleaning spray head 700 is designed to have a circular arc-shaped structure. As shown in FIGS.
  • cleaning water sprayed by a cleaning spray head with this structure will flow downwards along the filter screen 600, which may clean a large area of the filter screen 600 while saving product materials.
  • the water outlet of the filter screen cleaning spray head 700 may be processed into a circular arc-shaped water outlet, a plurality of small holes, or other forms according to actual needs.
  • the filter screen cleaning spray head 700 may also be designed to have a fan-shaped duckbill structure.
  • the filter screen cleaning spray head 700 may share a water inlet valve with a main water inlet pipe, or may be connected to a water inlet valve separately.
  • the filter screen cleaning spray head 700 For spray washing of the filter screen 600, if the filter screen cleaning spray head 700 shares a water inlet valve with the main water inlet pipe, the filter screen may be washed in a washing period. In a drying period, when the filter screen is blocked by too many impurities, a power of the fan 320 is decreased. In this case, a control panel of the fan 320 may output a signal to an upper computer, and the washing machine controls the water inlet valve to feed water for spraying after receiving the signal to clean the filter screen 600. If the filter screen cleaning spray head 700 is connected to a water inlet valve separately, it may be controlled separately according to actual needs.
