Definitions

  • the present invention relates to a laundry drying machine having an air heating channel, and in particular, to an air heating channel for use in such laundry drying machine.
  • a laundry drying machine usually has a drying compartment for holding laundry to be dried.
  • the drying compartment is connected to a condensation channel, a blowing apparatus, and an air heating channel. An outlet of the air heating channel is finally connected to the drying compartment.
  • the condensed water in the condensation channel and/or cooling water for heat exchange also enter(s) the air heating channel under the effect of the blowing apparatus.
  • the water that enters the air heating channel brings an abnormal change to a surface of the air heating channel, and abnormal control to signal collection of a temperature sensor.
  • the water enters the drying compartment from the air heating channel and wets laundry, and even a temperature fuse is abnormal, leading to various risks.
  • An objective of the present invention is to discharge water that enters an air heating channel.
  • the present invention provides a laundry drying machine having an air heating channel, where a heating apparatus is disposed in the air heating channel, the upstream of the air heating channel is connected to a condensation channel and a blowing apparatus, and the downstream is connected to a drying compartment.
  • a water blocking structure that blocks water and a water guiding structure that guides blocked water out of the air heating channel are disposed on the bottom of the air heating channel. Under the combined effect of the water blocking structure and the water guiding structure, the water that enters the air heating channel is blocked and discharged, so as to avoid an adverse impact brought by the water in the air heating channel or prevent the water from entering the drying compartment and wetting laundry.
  • the laundry drying machine includes various machines that may perform drying operations on laundry.
  • the water blocking structure may be implemented as a groove formed on a bottom wall of the air heating channel. After the water enters the groove, a flowing path is cut off.
  • the water guiding structure includes a water guiding hole formed on the bottom of the groove, and a water guiding channel connected to the water guiding hole. Through the water guiding structure, the water in the groove is guided out.
  • the water blocking structure may alternatively be implemented as a water blocking portion that rises up from a bottom surface of the air heating channel.
  • the water guiding structure may include a water guiding hole formed at the upstream of the water blocking portion and disposed close to the water blocking portion, and a water guiding channel connected to the water guiding hole.
  • the water blocking portion may be a protrusion integrated with the bottom wall of the air heating channel or a water blocking plate connected to the bottom wall of the air heating channel.
  • the water blocking structure is close to the inlet of the air heating channel. Therefore, most air heating channels are not affected by water.
  • the water blocking structure is located at the upstream of the heating apparatus.
  • the electronic components are disposed in the air heating channel, and the water blocking structure is located at the upstream of the electronic components. In this way, normal work and service life of the electronic components are ensured.
  • the electronic components may include a sensor and a temperature fuse.
  • the water blocking structure is a long-narrow structure, and has an extension direction crossed with an air flow direction in the air heating channel. Water that enters the air heating channel flows with airflow, and has a flow direction consistent with the air flow direction.
  • the water blocking structure crossed with the air flow direction cuts off the water flow direction.
  • upstream and downstream in this specification refer to the upstream and downstream of a flow direction of air blown by the blowing apparatus.
  • a laundry drying machine 100 has a drying compartment 2 that accommodates laundry, and an air heating channel 3 that is in fluid communication of the drying compartment 2.
  • a heating apparatus 6 is disposed in the air heating channel 3, to heat flowing air.
  • the upstream of the air heating channel 3 is connected to a condensation channel 4 and a blowing apparatus 5, and the downstream is connected to the drying compartment 2.
  • the other end of the condensation channel 4 is connected to the drying compartment 2.
  • the blowing apparatus 5 drives air to flow. Therefore, the air enters the drying compartment 2 after being heated in the air heating channel 3.
  • the high-temperature hot air exchanges heat with laundry in the drying compartment 2, and water in the laundry evaporates, and enters the condensation channel 4 with the air.
  • a water blocking structure 10 To block the water that enters the air heating channel 3, a water blocking structure 10, and a water guiding structure 20 that guides blocked water out of the air heating channel 3 are disposed on the bottom of the air heating channel 3.
  • the water blocking structure 10 should be disposed at the upstream of electronic components such as a sensor 7 and a temperature fuse 8.
  • the water blocking structure 10 may alternatively be located at the upstream of the heating apparatus 6.
  • the water blocking structure 10 is close to an inlet 31 of the air heating channel 3.
  • the water blocking structure 10 is a long-narrow structure, and has an extension direction crossed with an air flow direction in the air heating channel 3.
  • the water guiding structure 20 includes a water guiding channel 21.
  • An outlet of the water guiding channel 21 is connected to the bottom of the drying compartment 2, or another mechanism such as the condensation channel 4, so as to discharge water.
  • the water blocking structure 10 may be implemented as a groove 11 formed on a bottom wall 32 of the air heating channel 3.
  • a water guiding hole 22 is disposed on the bottom of the groove 11.
  • the water guiding channel 21 is connected to the water guiding hole 22.
  • the water guiding hole 22 constitutes a part of the water guiding structure 20.
  • the water blocking structure 10 may alternatively be implemented as a protrusion 12 that integrally rises up from a bottom surface 33 of the air heating channel 3.
  • the water guiding hole 23 is formed at the upstream of the protrusion 12 and is disposed close to the protrusion 12.
  • the water blocking structure 10 may alternatively be implemented as a water blocking plate 13 connected to the bottom wall 32 of the air heating channel 3.
  • the water guiding hole 24 is formed at the upstream of the water blocking plate 13 and disposed close to the water blocking plate 13.
