Description

Technical Field

[0001] This utility model relates to the technical field of dryer processing equipment, and more specifically to a heating cover assembly for a dryer. Background Technology

[0002] A clothes dryer is a household cleaning appliance that uses electric heating to instantly evaporate and dry the moisture in washed clothes.

[0003] However, existing electric heating dryers have high energy consumption and high cost, so many dryers now use heat pump dryers.

[0004] Existing heat pump dryers typically have heat exchange modules including a compressor, evaporator, condenser, and expansion valve, all of which are fixed to the bottom plate of the casing. Additionally, a water collection tank is fixed below the evaporator to collect condensate. This separate water collection tank is structurally complex and difficult to manufacture. Furthermore, because the water collection tank is located below the evaporator, the water pump's inlet pipe is obstructed by the evaporator, making installation difficult.

[0005] Meanwhile, existing dryer heat exchange modules typically only have one condenser and one evaporator, resulting in relatively low drying efficiency during use. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heating cover assembly for a clothes dryer. It has two condensers and one evaporator, which increases the volume of condensation and drying, thereby increasing the output of hot air and improving the drying effect. Moreover, the entire water receiving structure is directly formed at the bottom seat below the horizontally placed plate, and the water flows directly into the water receiving tank at the rear. This means that the water inlet pipe of the water pump only needs to be inserted into the water receiving tank. It is easy to install and has good performance.

[0007] The solution of this utility model to the aforementioned technical problem is:

[0008] A heating cover assembly for a clothes dryer includes a main housing. The main housing includes a bottom base. A front baffle portion extending upward is formed on the front side of the top surface of the bottom base. A middle baffle portion extending upward is formed in the middle of the top surface of the bottom base. A right baffle portion is formed on the right side of the top surface of the bottom base. A rear baffle portion extending obliquely to the left and rear is formed on the inner side wall of the rear part of the right baffle portion. The bottom surface of the rear baffle portion is formed on the top surface of the bottom base. A main heat exchange cavity is formed between the front baffle portion, the middle baffle portion, the right baffle portion, the rear baffle portion and the top surface of the bottom base. A main air inlet is formed on the part of the front baffle portion facing the main heat exchange cavity. The top surface of the main heat exchange cavity is covered with a top cover plate. The edge of the top cover plate is fixedly connected to the top surface of the front baffle portion, the middle baffle portion and the right baffle portion by bolts.

[0009] The main heat exchange chamber is equipped with an evaporator and two condensers. The evaporator is close to the front baffle, and the two condensers are side by side close to and behind the evaporator. The front side of the condenser is close to the rear of the evaporator, and the top surfaces of the evaporator and the two condensers are close to the bottom surface of the upper cover plate.

[0010] The top surfaces of the evaporator and the two condensers are pressed against a heat insulation plate, and the top surface of the heat insulation plate is fixed to the bottom surface of the upper cover plate.

[0011] The bottom surface of the main heat exchange cavity has an upwardly extending central protrusion. The left side wall of the central protrusion is formed on the right side wall of the central baffle. There is a front flow groove between the front end of the central protrusion and the front baffle. A right flow groove is formed between the right side of the central protrusion and the right side baffle. The front flow groove and the right flow groove are connected. The top surface of the central protrusion is an inclined wall surface that extends obliquely upward from the front end to the rear end.

[0012] A horizontal plate is fixed to the top surface of the central protrusion. The bottom surface of the horizontal plate presses against the rear of the top surface of the central protrusion. The bottom surface of the part of the horizontal plate directly above the right flow channel and the front flow channel is formed with multiple downwardly extending support protrusions. The bottom surface of the support protrusions presses against the bottom surface of the corresponding right flow channel and the front flow channel.

[0013] The front of the horizontally placed plate is formed with an elongated through groove extending to the left and right. The evaporator is installed at the front of the horizontally placed plate, with the bottom of the evaporator facing the elongated through groove.

[0014] The top surface of the horizontally placed plate behind the elongated through-slot is formed with left and right extending partitions and barriers. The two condensers are located behind the partitions and barriers and are installed on the horizontally placed plate.

[0015] A compressor assembly and a drive motor are mounted on the top surface of the bottom seat on the left side of the middle baffle portion. The output shaft of the drive motor is inserted into the middle through hole of the left extension plate formed at the rear end of the middle baffle portion. The middle part of the output shaft of the drive motor is located in a cavity between the left extension plate and the left end of the rear baffle portion formed at the left end, which is connected to the main heat exchange cavity.

[0016] The outstanding effect of this utility model is:

[0017] Compared with existing technologies, it has two condensers and one evaporator, which increases the volume of its condensation and drying process, thereby increasing the output of hot air and improving the drying effect. Moreover, the entire water receiving structure is directly formed at the bottom seat below the horizontally placed plate, and the water flows directly to the water receiving tank at the rear. This means that the water pump inlet pipe only needs to be inserted into the water receiving tank, making it easy to install and effective. Attached Figure Description

[0027] For example, see below. Figures 1 to 9 As shown, a heating cover assembly for a clothes dryer includes a main housing 10. The main housing 10 includes a bottom seat 11. A front baffle portion 12 extending upward is formed on the front side of the top surface of the bottom seat 11. A middle baffle portion 13 extending upward is formed in the middle of the top surface of the bottom seat 11. A right baffle portion 14 is formed on the right side of the top surface of the bottom seat 11. The front ends of the right baffle portion 14 and the middle baffle portion 13 are formed on the rear wall surface of the front baffle portion 12.

[0028] The inner wall of the rear part of the right side baffle 14 is formed with a rear baffle 15 extending obliquely to the left and rear. The bottom surface of the rear baffle 15 is formed on the top surface of the bottom seat 11. A main heat exchange cavity is formed between the front baffle 12, the middle baffle 13, the right side baffle 14, the rear baffle 15 and the top surface of the bottom seat 11. A main air inlet 121 is formed on the part of the front baffle 12 facing the main heat exchange cavity. The top surface of the main heat exchange cavity is covered with an upper cover plate 20. The edge of the upper cover plate 20 is fixedly connected to the top surface of the front baffle 12, the middle baffle 13 and the right side baffle 14 by bolts.

[0029] An evaporator 30 and two condensers 40 are installed in the main heat exchange chamber. The evaporator 30 is close to the front baffle 12, and the two condensers 40 are side by side close to and behind the evaporator 30. The front side of the front condenser 40 is close to the rear of the evaporator 30, and the top surfaces of the evaporator 30 and the two condensers 40 are close to the bottom surface of the upper cover plate 20.

[0030] Furthermore, the top surfaces of the evaporator 30 and the two condensers 40 are pressed against the heat insulation plate 1, and the top surface of the heat insulation plate 1 is fixed to the bottom surface of the upper cover plate 20.

[0031] Furthermore, the bottom surface of the main heat exchange cavity is formed with an upwardly extending central protrusion 16. The left side wall of the central protrusion 16 is formed on the right side wall of the central baffle portion 13. A front flow groove 161 is formed between the front end of the central protrusion 16 and the front baffle portion 12. A right flow groove 162 is formed between the right side of the central protrusion 16 and the right baffle portion 14. The front flow groove 161 and the right flow groove 162 are connected. The top surface of the central protrusion 16 is an inclined wall surface that extends obliquely upward from the front end to the rear end.

[0032] Furthermore, a horizontally placed plate 50 is fixed to the top surface of the central protrusion 16. The bottom surface of the horizontally placed plate 50 presses against the rear part of the top surface of the central protrusion 16. The bottom surface of the portion of the horizontally placed plate 50 directly above the right flow channel 162 and the front flow channel 161 is formed with multiple downwardly extending support protrusions. The bottom surface of the support protrusions presses against the bottom surface of the corresponding right flow channel 162 and the front flow channel 161.

[0033] The front of the horizontal placement plate 50 is formed with an elongated through groove 51 extending from left to right. Multiple first baffles 52 extending from left to right and multiple second baffles 53 extending from front to back are formed on the inner side wall of the elongated through groove 51. The first baffles 52 and the second baffles 53 are formed together at the intersection. The evaporator 30 is installed at the front of the horizontal placement plate 50, and the bottom of the evaporator 30 faces the elongated through groove 51.

[0034] Furthermore, a left-right extending partition 54 is formed on the top surface of the horizontally placed plate 50 behind the elongated channel 51. The two condensers 40 are located behind the partition 54 and mounted on the horizontally placed plate 50. The partition 54 can prevent the condensate from the evaporator 30 from flowing to the area below the condenser 40.

[0035] The top surfaces of the left and right sides of the horizontally placed plate 50 are each formed with upwardly extending side extensions 55. Two side through grooves are formed at the front of each side extension 55. Vertically extending slots are formed on the front and rear inner walls of each side through groove. All end plates on the same side of the evaporator 30 and the two condensers 40 are fixed to form a common end plate, with the front and rear parts of the common end plate inserted into corresponding slots. The slots enable the positioning of the evaporator 30 and the two condensers 40 during installation.

[0036] The rear end of the right-side flow channel 162 extends out of the rear baffle portion 15 and communicates with the water receiving channel 18 formed on the top surface of the rear part of the bottom seat 11.

[0037] A compressor assembly 60 and a drive motor 70 are mounted on the top surface of the bottom seat 11 at the left side of the middle baffle portion 13. The output shaft of the drive motor 70 is inserted into the middle through hole of the left extension plate 131 extending to the left at the rear end of the middle baffle portion 13. The middle part of the output shaft of the drive motor 70 is located in a cavity between the left extension plate 131 and the left extension portion 151 extending to the left at the left end of the rear baffle portion 15. This cavity is connected to the main heat exchange cavity.

[0038] In this embodiment, the outlet of the compressor assembly 60 is connected to the inlet of the condenser 40 behind it via a connecting pipe. The outlet of the condenser 40 behind it is connected to the inlet of the condenser 40 in front of it via a connecting pipe. The outlet of the condenser 40 in front of it is connected to the inlet of the capillary tube via a connecting pipe. The outlet of the capillary tube is connected to the inlet of the evaporator 30 via a connecting pipe. The outlet of the evaporator 30 is connected to the inlet of the compressor assembly 60 via a connecting pipe. This principle and structure are consistent with existing refrigeration systems and will not be described in detail here.

[0039] Furthermore, a left blocking portion is formed between the left extension plate 131 and the left end of the rear extension portion 151. The bottom end of the left blocking portion is formed on the top surface of the bottom seat 11. A left covering extension portion 21 is formed on the left side of the rear part of the upper cover plate 20, which covers the top surface of the cavity and is fixed to the top surface of the left blocking portion, the left extension plate 131 and the rear extension portion 151.

[0040] In this embodiment, an impeller (not shown in the attached figure) is fixed on the output shaft of the drive motor 70. The impeller is located in the cavity, and the air outlet in the middle of the rear end face of the cavity is connected to the inlet end of the dryer drum. The outlet end of the dryer drum is connected to the main air inlet 121. The dryer drum and other components of the dryer are conventional structures and will not be described in detail here.

[0041] It operates by driving motor 70, which allows air to circulate. After the air in the drying drum enters the main heat exchange chamber through air inlet 121, it first condenses through evaporator 30 (the temperature of the refrigerant in evaporator 30 is lower than that of the air). The resulting condensate drips down through elongated channel 51. Since the top surface of the central protrusion 16 is an inclined wall extending upward from the front end to the rear end, the condensate enters the right flow channel 162 and the front flow channel 161, and then flows to the water collection tank 18. A water pump can be installed on the upper part of the water collection tank 18 to extract the water from the water collection tank 18. The water collection tank 18 is located on the rear outer side, making it very convenient to insert the water inlet pipe of the water pump.

[0042] The condensed air flows through two condensers 40 (the refrigerant temperature in the condensers 40 is high), which causes its temperature to rise rapidly, raising the air temperature. Then, it enters the drying drum of the dryer through the air outlet in the middle of the rear end face of the cavity to dry the clothes. This cycle is repeated, resulting in good drying effect and high efficiency.

[0043] Finally, the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
