Description

Technical Field

[0001] This utility model relates to a dryer, and more particularly to an air-source heat pump circulating drum dryer. Background Technology

[0002] A dryer is a mechanical device specifically designed to remove moisture from items. It works by heating air or other gases and circulating these hot gases through the items to be dried, using convection to accelerate the evaporation of moisture inside the items. The moist air containing moisture is then expelled, thus achieving the purpose of quickly and effectively drying the items.

[0003] Traditional clothes dryers do not have a filtration function. During the operation of the dryer, as the clothes gradually dry, the cotton lint and other fabric debris attached to them also separate from the clothes. These cotton lint and other fabric debris will enter the external environment through the air outlet of the device, causing pollution to the user's living space and even affecting the user's respiratory health.

[0004] Therefore, it is necessary to design an air-source heat pump circulating drum dryer. Utility Model Content

[0005] In order to overcome the shortcomings of traditional clothes dryers that do not have a filtration function, which easily pollute the environment and affect the health of users, the technical problem to be solved by this utility model is: to provide an air source heat pump circulating drum dryer.

[0006] The technical solution of this utility model is: an air-source heat pump circulating drum dryer, including support feet, a box body, a door panel, a filter frame, a first spring, a filter screen, a clamping plate, a drum, an air-source heat pump, a connecting pipe, a motor, and a connecting assembly. The support feet are fixedly connected to the bottom of the box body. An air-source heat pump is installed on one side of the box body. The output end of the air-source heat pump is connected to the inside of the box body through the connecting pipe. A motor is installed on the side of the box body near the air-source heat pump. A drum is rotatably connected inside the box body. The output shaft of the motor is connected to the drum. A connecting assembly is provided on the side of the box body away from the motor. A door panel is connected to the box body through the connecting assembly. A filter frame is provided on the door panel. A filter screen is fixedly connected inside the filter frame. A first spring is provided between the door panel and the filter frame. A clamping plate for limiting the filter frame is rotatably connected to the door panel near the filter frame.

[0007] Furthermore, the filter frame is equipped with two layers of filter screens, and the mesh sizes of the two layers of filter screens are different. The mesh size of the filter screen closer to the inside of the box is larger, and the mesh size of the filter screen closer to the outside of the box is smaller.

[0008] Furthermore, the connecting assembly includes a rotating shaft, a guide rod, and a second spring. The guide rod is fixedly connected to the side of the housing facing away from the motor, and the rotating shaft is slidably connected to the guide rod. The end of the rotating shaft away from the guide rod is fixedly connected to the door panel. The guide rod is provided with a second spring, and the two ends of the second spring are respectively connected to the rotating shaft and the end of the guide rod away from the housing.

[0009] Furthermore, a baffle is fixedly connected inside the box near the connecting pipe.

[0010] Furthermore, telescopic casters are installed at the bottom of the container.

[0011] Furthermore, a wastewater collection tank is fixedly connected to the support legs.

[0012] The beneficial effects of this utility model are: 1. The design of the filter frame and the internal filter screen in this utility model effectively intercepts and collects fabric debris such as cotton lint, reduces the amount of pollutants emitted by the device, keeps the exhaust air clean, and greatly avoids pollution of the living space.

[0013] 2. This utility model, through its baffle design, not only prevents water droplets from splashing into the connecting pipe during the spin-drying process, but also blocks hot air from blowing directly onto the clothes, effectively protecting the clothes from damage and significantly improving the flexibility and practicality of the device.

[0014] 3. This utility model uses a motor to drive the drum to rotate, thereby tumbling the clothes. At the same time, an air-source heat pump provides high-temperature gas to heat the inside of the chamber. The two work together to greatly improve the drying efficiency. Attached Figure Description

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0022] Example: An air-source heat pump circulating drum dryer, such as Figures 1-5 As shown, the device includes a support leg 1, a housing 2, a door panel 3, a filter frame 301, a first spring 302, a filter screen 303, a retaining plate 304, a roller 4, an air source heat pump 5, a connecting pipe 501, a motor 6, and a connecting assembly. The support leg 1 is fixedly connected to the bottom of the housing 2. The air source heat pump 5 is installed on one side of the housing 2, and its output end is connected to the inside of the housing 2 through the connecting pipe 501. The motor 6 is installed on the side of the housing 2 near the air source heat pump 5. The roller 4 is rotatably connected inside the housing 2, and the output shaft of the motor 6 is connected to the roller 4. A connecting assembly is provided on the side of the housing 2 facing away from the motor 6. The door panel 3 is connected to the housing 2 through the connecting assembly. The filter frame 301 is provided on the door panel 3, and a filter screen is fixedly connected inside the filter frame 301. 303. A first spring 302 is provided between the door panel 3 and the filter frame 301. A retaining plate 304 for limiting the filter frame 301 is rotatably connected to the door panel 3 near the filter frame 301. The filter frame 301 has two layers of filter screens 303 inside, and the mesh size of the two layers of filter screens 303 is different. The mesh size of the filter screen 303 near the inner side of the box 2 is larger, and the mesh size of the filter screen 303 near the outer side of the box 2 is smaller. Here, by flipping the retaining plate 304 90 degrees, the retaining plate 304 is no longer in contact with the filter frame 301. At this time, the first spring 302 returns to its original compressed state. During the return process, the first spring 302 pushes the filter frame 301, thereby pushing the filter frame 301 out, so that the user can clean or replace the filter frame 301 as needed.

[0023] like Figure 3 As shown, the connecting assembly includes a rotating shaft 305, a guide rod 306, and a second spring 307. The guide rod 306 is fixedly connected to the side of the housing 2 facing away from the motor 6. The rotating shaft 305 is slidably connected to the guide rod 306. The end of the rotating shaft 305 away from the guide rod 306 is fixedly connected to the door panel 3. The guide rod 306 is provided with a second spring 307. The two ends of the second spring 307 are respectively connected to the rotating shaft 305 and the end of the guide rod 306 away from the housing 2.

[0024] like Figure 3 As shown, a baffle 502 is fixedly connected inside the housing 2 near the connecting pipe 501. The design of the baffle 502 can block splashing water droplets during the spin-drying process of the device, preventing water droplets from entering the connecting pipe 501. At the same time, it can block the hot air delivered by the air source heat pump 5, preventing the hot air from blowing directly on the clothes and avoiding damage to the clothes.

[0025] like Figure 5 As shown, telescopic casters 7 are installed at the bottom of the housing 2. The design of the telescopic casters 7 allows the device to move according to the user's needs. When the telescopic casters 7 extend, they lift the device, so that the support feet 1 no longer contact the ground, thus enabling free movement and improving the flexibility of the device.

[0026] like Figure 3 As shown, a wastewater collection tank 8 is fixedly connected to the support leg 1. Here, a drain outlet controlled by an electronic switch is provided at the bottom of the tank body 2. The wastewater collection tank 8 is designed to collect the waste liquid flowing out of the device's drain outlet after the device finishes its spin-drying operation, preventing the waste liquid from accumulating inside the tank body 2 and affecting the device's drying efficiency.

[0027] This device is used for drying clothes. In use, pull the door panel 3 outwards. The door panel 3 drives the rotating shaft 305 to move away from the cabinet 2, so that the door panel 3 is no longer in contact with the cabinet 2. Then, the guide rod 306 rotates the door panel 3 90 degrees to open the device. Next, place the clothes to be dried into the drum 4. Then, move the door panel 3 to the initial position to close the device. Then, start the motor 6. The output shaft of the drum 4 rotates, causing the connected drum 4 to rotate, thus rotating the clothes inside the drum 4, achieving a spin-drying effect and separating the clothes from the moisture. Then, start the air source heat pump 5. The air source heat pump 5 absorbs outside air and then converts the air into high-temperature gas through the heat pump circulation principle. This high-temperature gas is transported to the interior of the chamber 2 through the connecting pipe 501, and the interior temperature of the chamber 2 is heated. Through the coordinated operation of the motor 6 and the air source heat pump 5, the clothes are tumble dried. During the drying process, as the clothes gradually dry, the cotton lint and other fabric debris attached to them are separated from the clothes. These cotton lint and other fabric debris float under the action of hot air and drift with the air flow to the air outlet at the door panel 3. At this time, the filter screen 303 inside the filter frame 301 intercepts and collects the cotton lint and other fabric debris. The cotton lint and other fabric debris pass through the large mesh filter screen 303 and are intercepted by the small mesh filter screen 303, thus collecting the cotton lint and other fabric debris in the filter frame 301. This completes the filtration of the air discharged from the device.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
