Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, 2, a dryer according to an embodiment of the present application includes: a casing 10, a drum 20 installed in the casing 10, and a base 30 connected to a lower end of the casing 10.

The front end of the casing 10 is provided with an input passage 120 communicating with the front end of the drum 20, and laundry can be put into or taken out of the drum 20 through the input passage 120.

The housing 10 has a substantially hexahedral shape with a front cover, side covers, a rear cover, and a top cover defining the external appearance of the housing 10. The control panel is provided on the front cover and has a plurality of buttons for inputting a drying demand.

The dryer may include a front supporter 12 and a rear supporter 13 for supporting the drum 20. The front supporter 12 is coupled to a front end of the drum 20, and the rear supporter 13 is coupled to a rear end of the drum 20, that is, the front end of the drum 20 is supported by the front supporter 12, and the rear end of the drum 20 is supported by the rear supporter 13.

The front support 12 is hollow to form the above-mentioned input passage 120. The door 14 is installed at the front cover 111 corresponding to the input passage 120 for opening and closing the input passage 120.

The door 14 may include a door frame 141 and a glass member 142 protruding inward of the drum 20, and the drying of the laundry inside the drum 20 may be observed through the glass member 142. When the door 14 is at the closed position, the glass member 142 is inserted into the input passage 120.

The drum 20 is rotatably coupled with respect to the front support 12 and the rear support 13 for receiving laundry to be dried. The arrows in fig. 2 indicate the direction of the air flow, the front end opening of the drum 20 communicates with the input passage 120, the rear end of the drum 20 has an air inlet 21, and the communication between the inside of the drum 20 and the air inlet passage 61 is realized through the air inlet 21.

The air intake passage 61 is connected to the rear support 13 to communicate with the air inlet 21 of the drum 20 so that the air in the air intake passage 61 is supplied into the drum 20 through the air inlet 21. The exhaust passage 62 is connected to the front support 12, communicating with the drum 20.

The base 30 is provided with a heat exchanger cavity 31, and the heat exchanger cavity 31 is communicated with a front exhaust channel 62 and a rear intake channel 61. The air in the drum 20 enters the heat exchanger cavity 31 of the base 30 through the air inlet channel 61 and then is blown into the drum 20 through the air inlet 21 via the air inlet channel 61, thereby realizing the air flow circulation between the drum 20 and the base 30.

Referring to fig. 4 to 6, for the heat pump type clothes dryer, a heat pump system is generally disposed on the base 30, and the heat pump system may include a compressor 41, a condenser 42, an evaporator 45, a throttling device 44, a drying filter 43, and the like, which are connected in series through a refrigerant pipeline: an exhaust port of the compressor 41 is connected to an inlet of the condenser 42 through an exhaust pipe 46, a dry filter 43 and a throttle 44 are sequentially connected between an outlet of the condenser 42 and an inlet of the evaporator 45, and an outlet of the evaporator 45 is connected to an intake port of the compressor 41 through a suction pipe 47, thereby forming a refrigerant circuit.

Wherein, the condenser 42 and the evaporator 45 are arranged in the heat exchanger cavity 31, when a user loads clothes into the drum 20 and then operates the heat pump system, the heat pump system starts to work and simultaneously operates the compressor 41, because the compressor 41 operates, the refrigerant passing through the condenser 42 is changed into a high temperature state, and the refrigerant passing through the evaporator 45 is kept in a low temperature state.

The high-temperature and high-humidity air flowing through the clothes load enters the heat exchanger cavity 31, is cooled by the evaporator 45, then is subjected to heat exchange by the condenser 42 to form high-temperature dry air, and is circulated into the drum 20, so that the dehumidification and drying process of the clothes load is completed circularly.

The throttling device 44 and the dry filter 43 are connected to a refrigerant loop between the evaporator 45 and the condenser 42, the throttling device 44 may be an expansion valve or a throttling capillary tube, mainly keeps a high-low pressure difference between the evaporator 45 and the condenser 42, increases a heat exchange temperature difference between the refrigerant and air, and the dry filter 43 is used for removing moisture and impurities in the refrigerant.

In the related art, the throttling device 44 and the dry filter 43 are generally disposed near the compressor 41, so that the vibration generated when the compressor 41 is operated easily causes the intake and exhaust pipes to collide with the throttling device 44 and the dry filter 43, thereby generating abnormal sound and increasing the risk of leakage.

Therefore, in the embodiment of the clothes dryer of the present application, the throttling device 44 and the drying filter 43 are disposed in the heat exchanger cavity 31, so that the throttling device 44 and the drying filter 43 can be far away from the air inlet and outlet pipe, and the risk of collision is avoided.

In addition, in the related art, the throttling device 44 and the dry filter 43 are arranged outside the heat exchanger cavity 31, so that both a pipeline connecting the throttling device 44 with the evaporator 45 and a pipeline connecting the dry filter 43 with the condenser 42 need to pass through the side wall of the heat exchanger cavity 31, and an air inlet and exhaust pipe also needs to pass through the side wall of the heat exchanger cavity 31, so that four holes need to be arranged on the side wall of the heat exchanger cavity 31, and the air leakage risk of the heat exchanger cavity 31 is greatly increased.

In the present application, the throttling device 44 and the dry filter 43 are arranged in the heat exchanger cavity 31, and only two holes penetrating through the air inlet and outlet pipes need to be arranged on the side wall of the heat exchanger cavity 31, so that the air leakage risk of the heat exchanger cavity 31 can be reduced.

Specifically, referring to fig. 4, the base 30 further includes a compressor chamber 32, a compressor 41 is disposed in the compressor chamber 32, and the compressor 41 compresses a refrigerant and sends the compressed refrigerant to the condenser 6 to power the whole heat pump cycle. The discharge pipe 46 is connected to the discharge port of the compressor 41 and the inlet of the condenser 42, and delivers the high-temperature and high-pressure gas discharged from the compressor 41 to the condenser 45, and the suction pipe 47 is connected to the suction port of the compressor 41 and the outlet of the evaporator 45, and delivers the low-temperature and low-pressure gas of the evaporator 45 to the compressor 41 for compression.

Referring to fig. 5, a partition 33 is disposed on the base 30, and the partition 33 is used for separating the compressor cavity 32 and the heat exchanger cavity 31; the partition 33 is provided with holes for the suction pipe and the exhaust pipe to pass through, the holes include a first hole 331 and a second hole 332, the suction pipe 47 is disposed through the first hole 331, and the exhaust pipe 46 is disposed through the second hole 332.

Referring to fig. 3, the dryer may further include an upper cover 301 coupled to an upper end of the heat exchanger chamber 31 to close the heat exchanger chamber 31. The upper cover 301 is provided with an upper plate (not shown) abutting against the partition 33 on the base 30, the first hole 331 and the second hole 332 are arranged at the abutting joint of the upper plate and the partition 33, that is, the lower semicircle of the first hole 331 and the second hole 332 is arranged at the upper end of the partition 33, the upper semicircle of the first hole 331 and the second hole 332 is arranged at the lower end of the upper plate, and the lower semicircle and the upper semicircle are abutted into a whole circle, so that when the air suction pipe 47 is arranged at the first hole 331 from the upper end of the first hole 331, the exhaust pipe 46 is arranged at the second hole 332 from the upper end of the second hole 332, and the installation is not required to be carried out by penetrating the first hole 331 and the second hole 332, thereby improving the convenience and efficiency of installation.

In some embodiments of the present application, a first sheath is disposed outside the air suction pipe 47, a second sheath is disposed outside the air discharge pipe 46, the first sheath is located between the air suction pipe 47 and the first hole 331, and the second sheath is disposed between the air discharge pipe 46 and the second hole 332, so that the first hole 331 and the second hole 332 can be sealed by the first sheath and the second sheath, air leakage of the heat exchanger cavity 31 is further prevented, heat waste is avoided, and the work efficiency of the clothes dryer is ensured. The suction pipe 47 and the discharge pipe 46 are fixed at the first hole 331 and the second hole 332, respectively, and the first sheath and the second sheath can also relieve the collision caused by the vibration of the suction pipe 47 and the discharge pipe 46 when the compressor 41 vibrates.

In the correlation technique, it is relatively unset between evaporimeter 45 and the condenser 42, and both are mostly split type structures, and throttling arrangement 44, drier-filter 43, evaporimeter 45 and condenser 42 need place the welding behind base 30 during the installation, and the on-the-spot solder joint is too many, and base 30 is the working of plastics again, and on-the-spot welding can increase the risk of burning base 30.

Therefore, in the embodiment of the dryer of the present application, referring to fig. 6 to 9, the throttling means 44, the drying filter 43, the evaporator 45 and the condenser 42 are connected as an integrated structure, which can be pre-assembled, thereby reducing the number of assembly welding points disposed behind the base 30.

Specifically, the evaporator 45 and the condenser 42 are connected together; the two ends of the evaporator 45 are provided with the first end plates 451, the two ends of the condenser 42 are provided with the second end plates 421, and the first end plates 451 are connected with the second end plates 421, so that the evaporator 45 and the condenser 42 are fixed into a whole, the evaporator 45, the condenser 42, the throttling device 44 and the drying filter 43 can be welded into a whole in advance, welding spots on site are reduced, and the risk of burning out the base is reduced.

In the current embodiment, the first end plate 451 and the second end plate 421 are fixed as one body by a rivet; however, in other embodiments, the first end plate 451 and the second end plate 421 may be connected by screws or welding.

According to the embodiment of the present application, the first end plate 451 has the first extending portion 452 extending toward the condenser 42, the second end plate 421 has the second extending portion 422 extending toward the evaporator 45, and the first extending portion 452 is connected to the second extending portion 422. For example, referring to fig. 8 in particular, the first extending portion 452 and the second extending portion 422 are overlapped in a direction perpendicular to the first extending portion 452 or the second extending portion 422, and in the assembled state, the first extending portion 452 close to the end (lower end in the drawing) of the compressor 41 is located inside the second extending portion 422, and the first extending portion 452 far from the end (upper end in the drawing) of the compressor 41 is located outside the second extending portion 422.

Since the areas corresponding to the outer sides of the first extending portion 452 and the second extending portion 422 do not have the refrigerant elbow 48, in some embodiments of the present application, the throttling device 44 and the filter-drier 43 are correspondingly disposed in the areas outside the first extending portion 452 and the second extending portion 422, so as to fully utilize the empty space around the evaporator 45 and the condenser 42, thereby avoiding the problem that the volume of the heat exchanger cavity 31 is increased by disposing the throttling device 44 and the filter-drier 43 in the heat exchanger cavity 31.

During installation, the evaporator 45 and the condenser 42 can be connected firstly, and the throttling device 44, the drying filter 43, the evaporator 45 and the condenser 42 are arranged in the base 30 after being welded into an integrated structure, so that the problem of more welding points during split type welding can be solved.

According to the application, the throttling device 44 and the drying filter 43 are arranged in the heat exchanger cavity 31, only two holes passing through the air suction and exhaust pipe need to be arranged between the compressor cavity 32 and the heat exchanger cavity 31, and the arrangement of the holes is reduced, so that the risk of air leakage of the heat exchanger cavity 31 is reduced, and the efficiency of the clothes dryer is improved.

According to the application, the evaporator 45, the condenser 42, the throttling device 44 and the drying filter 43 are integrated into a whole structure, welding can be performed in a preassembling mode, assembling welding spots behind the base are reduced, and therefore the risk of burning the base is reduced.
