The embodiment of the application provides a base device for clothes drying equipment.

Referring to fig. 1, 4 and 8, the base device includes a base 1, a compressor 2 and a centrifugal fan 3 for dissipating heat of the compressor 2. The base 1 has a first chamber 1a and a second chamber 1b arranged in a longitudinal direction, and the compressor 2 is disposed in the first chamber 1 a; referring to fig. 4, the corresponding sidewall of the second chamber 1b has an opening 1J for communicating the second chamber 1b with the environment outside the drying apparatus.

Referring to fig. 6, the centrifugal fan 3 is disposed in the second chamber 1b, the centrifugal fan 3 has an air inlet 3a and an air outlet 31a, the air inlet 3a of the centrifugal fan 3 is communicated with the first chamber 1a, and the air outlet 31a of the centrifugal fan 3 is disposed through the opening 1J to guide the air flow from the first chamber 1a out of the clothes drying apparatus.

It should be noted that the centrifugal fan 3 is a fan that supplies air in the axial direction and discharges air in the radial direction. For example, referring to fig. 4, the centrifugal fan 3 includes a volute 31 and an impeller 32 disposed in the volute 31, the air inlet 3a is located on one side of the volute 31 along an axial direction of the impeller 32, and the air outlet 31a is located on one side of the volute 31 along a radial direction of the impeller 32. The size of the centrifugal fan 3 in the axial direction can be significantly smaller than the size in the radial direction, and therefore, the centrifugal fan 3 can occupy only a small size of the base 1 in the longitudinal direction, and can be installed in a small space of the second chamber 1 b.

It should be noted that the air outlet portion 31a and other portions of the volute casing 31 may be an integrally formed structure, or may be connected together in a split structure, for example, by screws, bolts, bonding, clamping, welding, etc.

The embodiment of the application still provides a dry clothing equipment, including barrel subassembly, box, circulation wind channel, evaporimeter, condenser and the base device of this application arbitrary embodiment. The drum assembly has a laundry treatment chamber; the barrel component is arranged in the box body; the circulating air duct is communicated with the clothes treatment cavity; the evaporator and the condenser are positioned on the circulating air duct, the evaporator is positioned at the upstream of the condenser along the airflow flowing direction, and the lower end of the box body is covered on the edge of the base 1.

The evaporator, the condenser, and the compressor 2 constitute a part of the heat pump system.

The working principle of the heat pump system is as follows: the compressor 2 sucks low-pressure gaseous refrigerant, the refrigerant is compressed by the compressor 2 and then discharged at high pressure, and the discharged high-pressure refrigerant enters the condenser, is cooled by air at normal temperature and is condensed into high-pressure liquid (meanwhile, heat is transferred to surrounding air); the high-pressure liquid refrigerant passes through the expansion valve for throttling and pressure reduction, then is changed into a low-pressure low-temperature gas-liquid two-phase mixture, and then enters the evaporator, the liquid refrigerant is evaporated and refrigerated in the evaporator (simultaneously absorbs heat in ambient air), and the generated low-pressure gaseous refrigerant is sucked by the compressor 2 again and then is pressurized, and the process is repeated in cycles and is circulated continuously, so that heat exchange is realized. The expansion valve may be replaced with a capillary tube.

The heat pump type clothes drying equipment realizes high utilization of energy, realizes low energy consumption, simultaneously the drying temperature of the heat pump system is far lower than the heating temperature of the electric heating element, and ensures the drying quality of clothes.

The working process and the clothes drying principle of the clothes drying equipment provided by the embodiment of the application are as follows: the drying hot air flow in the circulating air duct enters the clothes treatment cavity from the downstream of the circulating air duct along the air flow direction, the drying hot air flow flows through the surface of wet clothes in the clothes treatment cavity, the drying hot air flow exchanges heat and humidity with the wet clothes to absorb moisture in the clothes and becomes wet hot air flow, the wet hot air flow enters the upstream of the circulating air duct and sequentially flows through the evaporator and the condenser, the wet hot air flow is condensed and dehumidified by the evaporator in the process of flowing through the evaporator to form low-temperature drying air flow, and the low-temperature drying air flow is heated into the drying hot air flow when passing through the condenser. The hot drying air flow enters the clothes treatment cavity from the downstream of the circulating air duct again, and the clothes are continuously and efficiently dried by the circulating operation.

In the base device of the embodiment of the present application, the compressor 2 generates heat continuously in the working process, which causes the temperature in the first chamber 1a to rise, and the hot air in the first chamber 1a enters the volute 31 of the centrifugal fan 3 along the axial direction of the centrifugal fan 3 under the suction effect of the centrifugal fan 3, and then goes out along the radial direction of the centrifugal fan 3. Since the air outlet portion 31a of the centrifugal fan 3 is inserted into the opening 1J, the centrifugal fan 3 directly delivers the hot air flow to the outside of the clothes drying apparatus. In the air supply process of the centrifugal fan 3, the flow path of the air flow is short, and the centrifugal fan 3 realizes at least 90-degree turning of the air flow direction, so that the air quantity is not attenuated, the wind resistance is not generated, and the effective heat dissipation of the compressor 2 is ensured while the air quantity is not lost.

In addition, the compressor 2 is used as a noise source, and the air flow generates deflection of at least 90 degrees in the process of flowing through the volute 31, so that sound waves generated by the compressor 2 are reflected and attenuated in the volute 31 of the centrifugal fan 3, the sound waves radiated from the tail end of the air outlet part 31a are reverberant sound without direct sound, the sound wave energy emitted by the sound waves is gradually attenuated due to continuous absorption of the volute 31 in the transmission process due to reflection, the noise radiated outwards in the working process of the clothes drying equipment can be effectively reduced, and the user experience is improved.

Moreover, because centrifugal fan 3 has the characteristics of axial air inlet, radial air-out, in the narrow and small space on base 1, centrifugal fan 3 only needs to occupy the less vertical size of base 1, and centrifugal fan 3 can occupy a little great transverse dimension, consequently, centrifugal fan 3 can arrange in the corner of base 1, compact structure.

When the longitudinal direction of the base device is the front-back direction of the clothes drying equipment, the second chamber 1b is positioned at the front side of the first chamber 1a, and when the user stands in front of the clothes drying equipment, the feet of the user are positioned at the front side of the base device.

It should be noted that the hot air in the first chamber 1a is continuously sucked by the centrifugal fan 3, so that a certain negative pressure is formed in the first chamber 1a, and the air in the external environment can be supplemented into the first chamber 1a from the seam between the base 1 and the box body, or the seam between the box body and other structures.

The above-mentioned opening 1J may be located on the side wall of either lateral side of the second chamber 1 b. That is, the air outlet position of the air outlet portion 31a avoids the upper side, so that the wall surface interferes with the box body; the air outlet position of the air outlet part 31a can avoid the lower side, and the influence on air outlet caused by too close distance to the ground is avoided.

In one embodiment, the width of the second chamber 1b is no greater than the width of the first chamber 1a in the lateral direction of the base unit. Specifically, the width of the second chamber 1b is substantially the same as the width of the first chamber 1 a.

In one embodiment, the length of the second compartment 1b is substantially smaller than the length of the first compartment 1a in the longitudinal direction of the base unit. Specifically, the length of the second chamber 1b is 1/6-1/5 of the length of the first chamber 1 a.

It is to be noted that the evaporator and the condenser described above may be arranged at any suitable location of the drying apparatus. For example, in some embodiments, the evaporator and condenser may be disposed above the drum assembly. In other embodiments, the evaporator and condenser are disposed on the base, that is, below the cartridge assembly.

Illustratively, the base 1 comprises a third chamber 1c at one lateral side of the second chamber 1b, and referring to fig. 4 and 8, a space 1f is formed between an outer surface 1b 'of a side wall of the second chamber 1b facing the third chamber 1c and an outer surface 1 c' of a side wall of the third chamber 1c facing the second chamber 1b, that is, the space 1f is located in the external environment of the clothes drying equipment, and the end of the air outlet 31a is located in the space 1 f. In this embodiment, the end of the air outlet portion 31a is hidden in the space 1f, so as to prevent the air outlet portion 31a from being exposed on the appearance surface of the base and prevent the appearance surface of the base from being perforated, and thus the appearance surface of the base is not damaged.

In an embodiment, referring to fig. 4 to 8, the base device further includes a silencer 4 connected to the end of the air outlet portion 31a, the silencer 4 is disposed in the gap 1f, and the airflow discharged from the air outlet portion 31a flows through the silencer 4. The sound waves entering the muffler 4 from the air outlet portion 31a undergo at least one reflection during propagation to the outlet 4a of the muffler 4. The muffler 4 can further reduce the noise of the air flow and further attenuate the noise radiated outside by the clothes drying apparatus.

It is understood that the muffler 4 may not be additionally provided when the noise radiated from the air-out portion 31a has satisfied the preset standard.

The muffler 4 cannot affect the flow rate of the airflow and cannot affect the heat dissipation performance. In one embodiment, the muffler 4 is configured to: the flow direction of the air current discharged from the air outlet portion 31a is deflected by at least 90 °. For example, when the air outlet 31a exhausts along one lateral side, the outlet 4a of the muffler 4 may be located behind the muffler 4 toward the base device, on the one hand, avoiding exhausting hot air flow toward the user's feet, and on the other hand, avoiding affecting the smoothness of the air flow by being too close to the ground.

The specific structure of the muffler 4 is not limited. For example, referring to fig. 5 to 7, the muffler 4 has a substantially irregular box structure, the airflow is turned after entering the muffler 4, and during the turning process, the sound wave is continuously reflected by the inner wall of the muffler 4, and the sound wave energy is further attenuated, so that the muffler 4 can further reduce noise.

It should be noted that, when the noise requirement is higher, a sound absorbing material layer may be disposed on the inner wall of the muffler 4, and the sound wave energy is further attenuated by the sound absorbing material layer, so that the base device has better noise reduction performance. Since the sound-absorbing material layer is attached to the inner wall of the muffler 4, the sound-absorbing material layer does not substantially affect the flow of the air stream.

The sound absorption material layer is not limited to a specific material, and may be a porous sound absorption material, such as mineral wool, glass wool, felt, wood wool sound absorption board, and the like.

In one embodiment, the base 1 includes a partition wall between the first chamber 1a and the second chamber 1b, that is, the first chamber 1a is a longitudinal side of the partition wall, and the second chamber 1b is a longitudinal other side of the partition wall.

That is, the air flow in the first chamber 1a can only flow into the centrifugal fan 3 through the air holes 12a, so that negative pressure can be better generated around the compressor 2 in the first chamber 1a, and heat generated by the compressor 2 can be absorbed in time more effectively.

The specific arrangement of the partition wall is not limited as long as the first chamber 1a and the second chamber 1b can be partitioned.

Illustratively, referring to fig. 1 and 2, the base 1 includes an integrally molded main body 11, wherein the main body 11 is a main body structure of the base 1, and the main body 11 determines the outline and main structure of the base 1.

The arrangement is such that the flow of air between the first chamber 1a and the second chamber 1b does not affect the flow of air between the third chamber 1c and the fourth chamber 1 d.

It should be noted that the third chamber 1c and the fourth chamber 1d form a relatively closed space, and when the air current circulates between the circulating air duct and the clothes processing cavity, a certain air pressure can be formed in the third chamber 1c and the fourth chamber 1d, and the air pressure may be positive or negative relative to the standard atmospheric pressure.
