Description

Technical Field

[0001] The invention belongs to the technical field of clothes dryers, in particular to a clothes dryer with a hot air flow circulation function. Background Art

[0002] The development of clothes dryers stems from people's higher demand for clothes drying methods. It mainly consists of a clothes dryer body, a rotatable drum, a hot air blower and a condensing box. Its working method is that the operator places the clothes in the drum, and the hot air blower blows hot air from bottom to top. The hot air passes through the clothes and carries the moisture on the clothes upward through the exhaust pipe into the condensing box. The condensing box condenses the moisture in the hot air and discharges the dry gas. However, this method will make the heat discharged by the hot air blower unable to be recycled, which will cause the hot air blower to waste a lot of energy, thereby increasing the overall power consumption of the clothes dryer. Therefore, in order to solve the above problems, a clothes dryer with a hot air flow circulation function is proposed. Summary of the invention

[0003] To solve the problems raised in the above background technology, the present invention provides a clothes dryer with hot air circulation function, which solves the problem that the hot air discharged by the hot air blower cannot be recycled after being condensed, resulting in increased power consumption of the clothes dryer.

[0005] The drum mechanism comprises an isolation cover fixedly mounted inside the shell, a drum body is movably connected inside the isolation cover, and a driving assembly for driving the drum body to rotate is fixedly connected to the top of the door panel;

[0006] The circulating drying component includes a hot air blower and a condensing box body fixedly connected to the bottom of the shell, a heat exchange box is fixedly connected to the top of the condensing box body, an air outlet pipe and an air inlet pipe are also arranged on the hot air blower, the air outlet pipe is connected to the bottom of the isolation cover, the air inlet pipe horizontally passes through the heat exchange box and is connected to the outside world, the part of the air inlet pipe located inside the heat exchange box is flat, a pipe 2 connected to the condensing box body is fixedly connected to the bottom of the heat exchange box, a pipe 1 connected to the outside world is arranged on the side of the condensing box body, a pipe 3 connected to the top of the isolation cover is fixedly connected to the top of the heat exchange box, a drain pipe is also fixedly connected to the bottom of the condensing box body, and a condensing pipe is fixedly connected to the inside of the condensing box body.

[0007] Preferably, the outer periphery of the air inlet pipe and the portion located inside the heat exchange box are also fixed with heat conducting fins at equal intervals.

[0008] Preferably, a porous plate is fixedly connected inside the air inlet pipe.

[0009] Preferably, a spiral fin is fixedly connected to the interior of the second pipe, and the heat exchange box is connected to the interior of the condensation box through a gap between the spiral fin and the second pipe.

[0010] Preferably, the regulating assembly comprises a cover body fixedly connected to the condensing box body and the heat exchange box respectively, and an electric partition plate is fixedly connected to the middle of the cover body;

[0011] The electric partition plate divides the cover into two parts, an upper part and a lower part;

[0012] One end of the air inlet pipe and the pipeline one respectively extends to the upper part and the lower part of the cover body, and both are connected with the outside through the cover body.

[0013] Preferably, a connecting cover is fixedly connected to the bottom of the isolation cover, and the air outlet pipe is connected to the isolation cover through the connecting cover.

[0014] Preferably, both sides of the connection cover are fixedly connected with a pipe four, the top end of the pipe four passes through the isolation cover and extends to the inside of the isolation cover, and the top of the pipe four is flat and faces the inner wall of the isolation cover.

[0015] Preferably, a valve flap is symmetrically fixed inside the connection cover, and one opposite end of the valve flap cooperates to seal;

[0016] The bottom end of the pipeline 4 is located below the valve disc.

[0017] Preferably, a plurality of guide plates located above the valve disc are also provided at the bottom of the isolation cover.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The above scheme drives the drum body to rotate in the isolation cover by running the driving component, and runs the hot air blower to transport the hot air flow from the bottom of the isolation cover upward through the air outlet pipe. The hot air flow passes through the clothes and the drum body and rises to the top of the isolation cover. Then the hot air flow enters the heat exchange box through the pipe three. At the same time, the outside air will enter the air inlet pipe through the regulating component. At this time, the outside will be preheated by the hot air flow transported by the pipe three through the flat part of the air inlet pipe and enter the hot air blower. Since the air inlet pipe and the pipe one are close to each other and are both connected to the outside through the regulating component, the small amount of cold air discharged from the pipe one will be extracted by the air inlet pipe and preheated for use, thereby improving the utilization efficiency of the hot air flow and reducing the power consumption of the dryer.

[0020] The above scheme connects the upper and lower parts of the cover body by rotating the electric partition plate. At this time, the dry cold air discharged from the first pipe will enter the air inlet pipe through the cover body. At this time, the air inlet pipe will extract the outside air and the cold air discharged from the first pipe, and mix them through the porous plate and then be preheated, thereby improving the dryness of the air extracted from the air inlet pipe, so as to improve the dryness of the hot air heated by the hot air blower and transported through the air outlet pipe, thereby improving the drying efficiency of the clothes.

[0021] In the above scheme, the hot air transported by the air outlet pipe enters the connecting cover. Due to the obstruction of the valve disc, the pressure of the gas inside the connecting cover increases. At this time, the gas inside the connecting cover will first enter the pipe four, and be discharged through the top of the pipe four to form a layer of hot air flow barrier on the inner wall of the isolation cover. At the same time, the air flow inside the connecting cover will also push the valve disc open and slowly rise after being guided by the guide plate to dry the clothes. At this time, part of the hot air flow carrying water vapor is blocked by the hot air flow barrier, which prevents a large number of water droplets from condensing on the inner wall of the isolation cover to reduce the drying effect of the device.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides a clothes dryer with a hot air circulation function, comprising a housing 1 and a drum mechanism 2, wherein the housing 1 comprises an isolation plate 11 and a door plate 12 installed inside the housing 1, and further comprises: a circulation drying component 3 installed at the bottom of the housing 1; an adjustment component 4 used to adjust the ratio of the circulation drying component 3 and the external air circulation;

[0033] The drum mechanism 2 includes an isolation cover 21 fixedly installed inside the housing 1, a drum body 22 is movably connected inside the isolation cover 21, and a driving assembly 23 for driving the drum body 22 to rotate is fixedly connected to the top of the door panel 12;

[0034] The circulating drying component 3 includes a hot air blower 31 and a condensing box 32 fixedly connected to the bottom of the shell 1, a heat exchange box 33 is fixedly connected to the top of the condensing box 32, an air outlet pipe 311 and an air inlet pipe 312 are also arranged on the hot air blower 31, the air outlet pipe 311 is connected to the bottom of the isolation cover 21, the air inlet pipe 312 horizontally penetrates the heat exchange box 33 and is connected to the outside, the part of the air inlet pipe 312 located inside the heat exchange box 33 is flat, a pipe 2 331 connected to the condensing box 32 is fixedly connected to the bottom of the heat exchange box 33, a pipe 1 321 connected to the outside is arranged on the side of the condensing box 32, a pipe 3 34 connected to the top of the heat exchange box 33 is fixedly connected to the top of the isolation cover 21, a drain pipe 322 is also fixedly connected to the bottom of the condensing box 32, and a condensing pipe 323 is fixedly connected to the inside of the condensing box 32;

[0035] The outer periphery of the air inlet pipe 312 and the portion located inside the heat exchange box 33 are also fixed with heat conducting fins 3121 at equal intervals;

[0036] By adopting the above scheme, the drum body 22 is driven to rotate in the isolation cover 21 by running the driving component 23, and the hot air blower 31 is operated to transport the hot air flow from the bottom of the isolation cover 21 upward through the air outlet pipe 311. The hot air flow passes through the clothes and the drum body 22 and rises to the top of the isolation cover 21. Then, the hot air flow enters the heat exchange box 33 through the pipe three 34. At the same time, the external air will enter the air inlet pipe 312 through the regulating component 4. At this time, the outside will be preheated by the hot air flow transported by the pipe three 34 through the flat part of the air inlet pipe 312 and enter the hot air blower 31. Since the air inlet pipe 312 and the pipe one 321 are close to each other and are both connected to the outside through the regulating component 4, a small amount of cold air discharged from the pipe one 321 will be extracted by the air inlet pipe 312 and preheated for use, thereby improving the utilization efficiency of the hot air flow and reducing the power consumption of the dryer.

[0037] The installation of the heat-conducting fins 3121 can increase the efficiency of the exchange between the air inlet pipe 312 and the hot air inside the heat exchange box 33 .

[0038] like Figure 2 , Figure 3 and Figure 7 As shown, the regulating assembly 4 includes a cover body 41 which is fixedly connected to the condensing box 32 and the heat exchange box 33 respectively, and an electric partition plate 42 is fixedly connected to the middle of the cover body 41;

[0039] The electric partition plate 42 divides the cover body 41 into two parts, the upper and lower parts; the air inlet pipe 312 and one end of the pipe 1 321 extend to the upper and lower parts of the cover body 41 respectively, and both are connected to the outside through the cover body 41;

[0040] A porous plate 3122 is also fixedly connected inside the air inlet pipe 312;

[0041] By adopting the above scheme, the upper and lower parts of the cover body 41 are connected by operating the electric partition plate 42 to rotate. At this time, the dry cold air discharged from the pipe 321 will enter the air inlet pipe 312 through the cover body 41. At this time, the air inlet pipe 312 will draw the external gas and the cold air discharged from the pipe 321, and mix them through the porous plate 3122 and then be preheated, thereby improving the dryness of the gas extracted by the air inlet pipe 312, so as to improve the dryness of the hot air heated by the hot air blower 31 and then transported through the air outlet pipe 311, thereby improving the drying efficiency of the clothes.

[0042] like Figure 3 As shown, a spiral fin 3311 is fixedly connected to the inside of the second pipe 331, and the heat exchange box 33 is connected to the inside of the condensation box 32 through the gap between the spiral fin 3311 and the second pipe 331;

[0043] By adopting the above solution, through the design of the spiral fins 3311, it is avoided that the hot air transported from the heat exchange box 33 to the condensation box 32 will disturb the cold air inside the condensation box 32, causing the cold air to reversely enter the heat exchange box 33 and affect the preheating efficiency of the air flow inside the air inlet pipe 312.

[0044] like Figure 1 and Figure 4-7 As shown, the bottom of the isolation cover 21 is fixedly connected to a connecting cover 5, and the air outlet pipe 311 is connected to the isolation cover 21 through the connecting cover 5;

[0045] Both sides of the connection cover 5 are fixedly connected with a pipe 4 51, the top of the pipe 4 51 passes through the isolation cover 21 and extends to the inside of the isolation cover 21, and the top of the pipe 4 51 is flat and faces the inner wall of the isolation cover 21;

[0046] A valve flap 52 is symmetrically fixed inside the connection cover 5, and the valve flap 52 cooperates with one end of the opposite end to seal; the bottom end of the pipeline 4 51 is located below the valve flap 52;

[0047] The bottom of the isolation cover 21 is also provided with a plurality of guide plates 53 located above the valve flap 52;

[0048] By adopting the above scheme, the hot air transported through the air outlet pipe 311 enters the connecting cover 5. Due to the obstruction of the valve flap 52, the pressure of the gas inside the connecting cover 5 increases. At this time, the gas inside the connecting cover 5 will first enter the pipe four 51, and be discharged through the top of the pipe four 51 and form a layer of hot air flow barrier on the inner wall of the isolation cover 21. At the same time, the air flow inside the connecting cover 5 will also push the valve flap 52 open and be guided by the guide plate 53 and then slowly rise to dry the clothes. At this time, part of the hot air flow carrying water vapor is blocked by the hot air flow barrier, which prevents a large number of water droplets from condensing on the inner wall of the isolation cover 21 to reduce the drying effect of the device.

[0049] The working principle and use process of the present invention:

[0050] The clothes to be dried are placed into the drum body 22 after the isolation plate 11 is opened, and then the isolation plate 11 is closed to seal the front end of the drum body 22;

[0051] The operation drive component 23 drives the drum body 22 to rotate in the isolation cover 21, and the operation hot air blower 31 transports the hot air flow from the bottom of the isolation cover 21 upward through the air outlet pipe 311. The hot air flow passes through the clothes and the drum body 22 and rises to the top of the isolation cover 21. Then the hot air flow enters the heat exchange box 33 through the pipe three 34, and at the same time, the external air enters the air inlet pipe 312 through the regulating component 4. At this time, the outside world will be preheated by the hot air flow transported by the pipe three 34 through the flat part of the air inlet pipe 312 and enter the hot air blower 31. Then the hot air flow carrying water vapor will enter the condensation box 32 through the pipe two 331 and be condensed and dried by the condensation pipe 323. The gas is discharged through the pipe one 321 and the regulating component 4, and the condensed water is discharged through the drain pipe 322. Since the air inlet pipe 312 and the pipe one 321 are close to each other and are both connected to the outside world through the regulating component 4, at this time, a small amount of cold air discharged from the pipe one 321 will be extracted by the air inlet pipe 312 and preheated for use;

[0052] By operating the electric partition plate 42 to rotate, the upper and lower parts of the cover body 41 are connected, and the dry cold air discharged from the pipe 1 321 will enter the air inlet pipe 312 through the cover body 41. At this time, the air inlet pipe 312 will extract the outside air and the cold air discharged from the pipe 1 321, and mix them through the porous plate 3122 and then be preheated, thereby improving the dryness of the air extracted by the air inlet pipe 312, so as to improve the dryness of the hot air heated by the hot air blower 31 and transported through the air outlet pipe 311, thereby improving the effect of improving the drying efficiency of the clothes;

[0053] When the hot air transported by the air outlet pipe 311 passes through the connecting cover 5, the pressure of the gas inside the connecting cover 5 increases due to the obstruction of the valve flap 52. At this time, the gas inside the connecting cover 5 will first enter the pipe four 51, and be discharged through the top of the pipe four 51 and form a layer of hot air flow barrier on the inner wall of the isolation cover 21. At the same time, the air flow inside the connecting cover 5 will also push the valve flap 52 open and be guided by the guide plate 53 and then slowly rise to dry the clothes. At this time, part of the hot air flow carrying water vapor is blocked by the hot air flow barrier, which prevents a large amount of water droplets from condensing on the inner wall of the isolation cover 21 to reduce the drying effect of the device.
