Description

Technical Field

[0001] This invention belongs to the field of clothes dryers, and specifically relates to a clothes dryer and a clothes dryer door with an auxiliary drying device. Background Technology

[0002] Current clothes dryers are mainly divided into vented dryers, condenser dryers, and heat pump dryers. They work by sending hot air into the drum to evaporate the moisture in the clothes. The evaporated moisture is then expelled from the drum with the hot air, thus drying the clothes. However, in existing technologies, the hot air mostly enters the drum from the back. During the drying process, especially when there are many clothes, the clothes at the back of the drum dry faster under the action of the high-temperature gas, while the clothes at the front of the drum are not fully blown by the hot air, resulting in a slower drying speed. This leads to uneven drying inside the dryer.

[0003] Chinese utility model patent application number CN204982471U discloses a clothes dryer with an air guiding mechanism, including a heating wire assembly, a motor, and a circulating fan wheel, all mounted on the rear cover of the drum. An air guiding mechanism is provided on the outside of the heating wire assembly. The air generated by the fan wheel is heated by the heating wire assembly and then blown in different directions inside the dryer drum under the guidance of the air guiding mechanism, thereby improving the uniformity of drying. Although the above solution solves the problem of uneven drying to some extent, since the hot and dry air still enters the drum from the rear, the clothes located in front of the dryer drum cannot be fully dried.

[0004] Chinese utility model patent application number CN211256421U discloses a clothes dryer with ventilation holes on the inner side of the drum and an annular heating air duct on the outer side of the drum. The inner side of the annular heating air duct is tumblingly connected to the outer side of the drum. Dry hot air enters the drum through the ventilation holes to achieve uniform drying of clothes. Although the above solution improves the uniformity of drying clothes, the capacity of the drum is reduced because the drum consists of two tumblingly connected layers.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The purpose of this invention is to address the problems in the prior art by providing a dryer and a dryer door with an auxiliary drying device. The auxiliary drying device is located inside the dryer door and improves the temperature uniformity of the front and rear sides of the drum when the dryer dries clothes by sending air heated by the auxiliary drying device into the front side of the dryer drum.

[0007] To achieve the above objectives, a first aspect of the present invention provides a dryer door with an auxiliary drying device, the auxiliary drying device being disposed inside the door, and the door having an air inlet and an air outlet. The auxiliary drying device includes...

[0008] The air duct assembly is connected to the air inlet and air outlet respectively;

[0009] Heating components are used to heat the air inside the air duct assembly;

[0010] A fan, connected to the duct assembly, is used to exhaust heated air from the outlet.

[0011] The above solution improves the temperature uniformity of the front and rear ends of the dryer drum by placing the auxiliary drying device inside the dryer door, while making full use of the internal space of the door and avoiding the auxiliary drying device occupying the internal space of the dryer.

[0012] Furthermore, the air duct assembly includes an air inlet duct connected to the air inlet and an air outlet duct connected to the air outlet, and the fan is connected to the air inlet and the air outlet respectively through the air inlet duct and the air outlet duct.

[0013] Furthermore, the air inlet duct includes a first air guide portion, which covers the air inlet and is recessed into the door body to form the air inlet duct; the air outlet duct includes a second air guide portion, which covers the air outlet and is recessed into the door body to form the air outlet duct.

[0014] Furthermore, the depth to which the second air guide is recessed into the door body is greater than the depth to which the first air guide is recessed into the door body and less than the distance between the inner wall and the outer wall of the door body, and the fan and the air inlet duct are located below the air outlet duct.

[0015] In the above scheme, the recessed depth of the first air guide and the second air guide is less than the distance between the inner wall and the outer wall of the door, so that the auxiliary drying device can be smoothly installed inside the door. The recessed depth of the second air guide is greater than that of the first air guide. While the air inlet duct is located below the air outlet duct, the fan can also be located below the air outlet duct, which reduces the overall size of the auxiliary drying device and makes it easier to install the auxiliary drying device inside the door.

[0016] Furthermore, the fan is connected to the air inlet duct and the air outlet duct through connection ports respectively provided on the first air guide section and the second air guide section.

[0017] Furthermore, the cross-sectional areas of the air inlet duct and the air outlet duct gradually decrease along the concave direction.

[0018] The above scheme gives the air inlet duct a larger air inlet area, reduces air inlet resistance, and lowers the noise of the auxiliary drying device. The cross-sectional area of ​​the air outlet duct gradually decreases along the concave direction, allowing the airflow to stay in the air outlet duct for a longer time, improving the heating effect of the heating component on the airflow, and also enabling the heated dry air to diffuse evenly.

[0019] Furthermore, the air duct assembly also includes a fixing plate, which is fixedly connected to the air inlet duct and the air outlet duct respectively. The air inlet duct, the air outlet duct and the fixing plate are integrally formed, and the fan is detachably fixed to the fixing plate.

[0020] In the above solution, the air inlet duct, air outlet duct, and fixed plate are integrally formed, and the fan is fixed on the fixed plate, which realizes the stable connection of various components of the auxiliary drying device and improves the stability of the auxiliary drying device.

[0021] Furthermore, one end of the fixing plate is connected to the side of the air outlet duct, and the air inlet duct and the fan are respectively fixed on opposite sides of the fixing plate.

[0022] The above solution reduces the overall size of the auxiliary drying device by placing the air inlet duct and fan on both sides of the fixed plate, allowing the auxiliary drying device to be installed inside the door without affecting the size and thickness of the door.

[0023] Furthermore, the inner wall of the door is provided with an outwardly protruding protrusion structure, and the side of the protrusion structure facing the inside of the door forms a cavity. The air inlet and air outlet are located on the outwardly protruding side of the protrusion structure, and the auxiliary drying device is located inside the cavity.

[0024] Preferably, the protruding structure is an observation window.

[0025] Alternatively, as an alternative to the above solution, the air inlet can be located on the outer wall of the door, and the air outlet can be located on the side of the protruding structure that protrudes outward.

[0026] A second aspect of the present invention also provides a clothes dryer having the clothes dryer door body described in the above-described solution.

[0027] Furthermore, the end of the air outlet duct connected to the door faces the inside of the dryer and communicates with the inside of the dryer through a through hole provided on the door.

[0028] The beneficial effects of this invention are as follows: The auxiliary drying device is located inside the dryer door, avoiding the space occupied by the auxiliary drying device inside the dryer drum; the air inlet duct and the air outlet duct are respectively connected to the same side or opposite sides of the door, allowing the auxiliary drying device to circulate and heat the air on one side of the door, or heat the air on one side of the door and send it to the other side, increasing user selectivity; the air inlet duct is formed by a first air guide covering the air inlet and recessing into the door, and the air outlet duct is formed by a second air guide covering the air outlet and recessing into the door. The depth of the second air guide recessing into the door is greater than the depth of the first air guide recessing into the door and less than the distance between the inner and outer walls of the door, without altering the... The auxiliary drying system is installed inside the door body without compromising its aesthetics or increasing production costs due to structural changes, while the door body size and structure can be modified. The air inlet and outlet ducts are connected to the fixed plate, and these ducts and the fixed plate are integrally formed. The fan is detachably fixed to the fixed plate, making the auxiliary drying device more compact and the connection between the fan and duct components more stable, thus improving the stability of the auxiliary drying device. The cross-sectional area of ​​the air inlet and outlet ducts gradually decreases along the concave direction, reducing airflow resistance and operating noise while allowing the airflow to remain in the outlet duct for a longer time, resulting in more thorough heating by the heating components and improving the heating efficiency of the auxiliary drying device.

[0036] Example 1

[0037] As an embodiment of the present invention, this embodiment provides a door with an auxiliary drying device, the structure of which is as follows: Figure 1 As shown, the door body is provided with an outwardly protruding observation window 4. The side of the observation window 4 facing the inside of the door body forms a cavity. The air inlet 41 and the air outlet 42 are located on the outwardly protruding side of the observation window. The auxiliary drying device is located inside the cavity and includes a fan 2, a heating component 3, and an air duct component 1. The air duct component 1 is connected to the air inlet 41 and the air outlet 42 respectively. The fan 2 is connected to the air duct component 1 and is connected to the air inlet 41 and the air outlet 42 through the air duct component 1.

[0038] The above solution enables the circulating heating of air on one side of the dryer door.

[0039] In this embodiment, the structure of the air duct assembly 1 is as follows: Figure 2 and Figure 3 As shown, the air inlet 41 is located below the air outlet 42. The air duct assembly includes an air inlet duct 12 communicating with the air inlet 41, an air outlet duct 11 communicating with the air outlet 42, and a fixing plate 13 connecting the air inlet duct 12 and the air outlet duct 11. The air inlet duct 12, the air outlet duct 11 and the fixing plate 13 are integrally formed. The fan is connected to the air inlet 41 and the air outlet 42 through the air inlet duct 12 and the air outlet duct 11, respectively.

[0040] Furthermore, the air inlet duct 12 includes a first air guide 121, which covers the air inlet 41 and is recessed into the door body to form the air inlet duct 12. The air outlet duct 11 includes a second air guide 111, which covers the air outlet 42 and is recessed into the door body to form the air outlet duct 11.

[0041] Furthermore, the depth of the second air guide 111 recessed into the door body is greater than the depth of the first air guide 121 recessed into the door body and less than the distance between the inner wall and outer wall of the door body opposite to the position of the second air guide 111. The fan 2 and the air inlet duct 12 are located below the air outlet duct 11.

[0042] The above solution allows the auxiliary drying device to be installed inside the door. At the same time, the depth of the air outlet duct 11 is greater than the depth of the air inlet duct 12, so that the air inlet duct 12 and the fan can be set below the air outlet duct 11, making the auxiliary drying device have a more compact structure and preventing the fan 2 from protruding from the duct assembly and affecting the overall structure of the door.

[0043] Furthermore, one end of the fixing plate 13 is connected to the side of the air outlet duct 11, and the air inlet duct 12 and the fan 2 are respectively fixed on opposite sides of the fixing plate 13.

[0044] The above solution achieves a more stable and tighter connection between the fan 2 and the air duct assembly by fixing the fan 2 to the fixed plate 13, thereby improving the stability of the auxiliary drying device.

[0045] Furthermore, based on the above scheme, the fan 2 is connected to the air inlet duct 12 and the air outlet duct 11 through connection ports respectively provided on the first air guide section 121 and the second air guide section 111.

[0046] Furthermore, the connection port is set close to the fixing plate 13, and the air outlet of the fan 2 can be directly inserted into the connection port to connect with the air outlet duct 11, avoiding the need to set up an additional connection duct, which would increase the overall size of the auxiliary drying device.

[0047] Furthermore, on the other side of the connection port opposite to the fixing plate 13, there is a baffle rib protruding outward from the air outlet duct 11 parallel to the fixing plate 13. The fixing plate 13 is provided with a convex rib protruding to the side where the fan 2 is fixed. The fan 2 is positioned by the baffle rib and the convex rib.

[0048] In the above scheme, when the fan 2 is installed in place, the fixing plate 13 and the baffle can position the air outlet of the fan 2. At the same time, the outer shell of the fan 2 is tightly attached to the protruding rib on the fixing plate 13 to prevent the fan 2 from falling off due to vibration, thereby improving the stability of the auxiliary drying device.

[0049] Furthermore, the air inlet duct 12 and the air outlet duct 11 are provided with a first fixing member 5 extending outward from the duct. When the auxiliary drying device is installed in place, the first fixing member 5 is attached to the door wall on the side of the door with the observation window 4, and the auxiliary drying device is fixed inside the door by the first fixing member 5.

[0050] Furthermore, the cross-sectional areas of the air inlet duct 12 and the air outlet duct 11 gradually increase along the direction away from the fan 2.

[0051] The above solution reduces air intake resistance and lowers the operating noise of the auxiliary drying device, while allowing the airflow to stay in the air outlet duct 11 for a longer time and be heated more fully by the heating component 3, thereby improving the heating efficiency of the auxiliary drying device.

[0052] Example 2

[0053] As another embodiment of the present invention, this embodiment provides a door with an auxiliary drying device. The door is provided with an air inlet and an air outlet. The auxiliary drying device is located inside the door and includes a fan, a heating component and an air duct component.

[0054] In this embodiment, the air inlet and air outlet are located on the inner wall of the door, with the air inlet located below the air outlet. The air duct assembly includes independently set air inlet and air outlet ducts. The air inlet end of the fan is connected to the air inlet on the door through the air inlet duct, and the air outlet end of the fan is connected to the air outlet end on the door through the air outlet duct.

[0055] In the above solution, the air outlet is located above the air inlet to prevent hot air from blowing directly onto the clothes, thus improving the uniformity and effectiveness of drying while avoiding damage to the clothes.

[0056] Furthermore, the air inlet duct includes a first air guide section, which covers the air inlet and is recessed into the door body to form the air inlet duct, and the air outlet duct includes a second air guide section, which covers the air outlet and is recessed into the door body to form the air outlet duct.

[0057] Furthermore, the air inlet and air outlet ducts are provided with connecting ports, and the air inlet and air outlet of the fan are connected to the air inlet and air outlet ducts respectively through the connecting ports provided on the air inlet and air outlet ducts.

[0058] Furthermore, a sealing ring is provided at the connection port. The fan passes through the connection port and achieves a tight connection with the air inlet and outlet ducts through the sealing ring.

[0059] Furthermore, the depth of the second air guide recess into the door body is greater than the depth of the first air guide recess into the door body and less than the distance between the inner and outer walls of the door body. The fan and the air inlet duct are located below the air outlet duct.

[0060] In the above solution, the auxiliary drying device can be smoothly installed inside the door. At the same time, the depth of the air outlet duct is greater than the depth of the air inlet duct, so the air inlet duct and the fan can be set below the air outlet duct, making the auxiliary drying device have a more compact structure and preventing the fan from protruding from the duct assembly. This allows the auxiliary drying device to be installed inside the door without increasing the door thickness.

[0061] Furthermore, the air inlet of the fan is fixedly connected to the connecting port on the air inlet duct, and the air outlet of the fan is fixedly connected to the connecting port on the air outlet duct.

[0062] The air inlet duct and air outlet duct are connected to the door body at one end, and a first fixing member is provided on the first fixing member. The first fixing member is provided with a through hole for screws to pass through. The screws pass through the through hole to fix the auxiliary drying device inside the door body.

[0063] In the above scheme, the air inlet and air outlet of the fan are fixedly connected to the connecting ports on the air inlet and air outlet ducts, respectively, to prevent the fan from falling off due to vibration; the fan is fixed inside the door body by the fixing parts set on the air inlet and air outlet ducts, realizing the connection between the auxiliary drying device and the door body, and improving the stability of the auxiliary drying device.

[0064] Furthermore, the first fixing member extends outward from the end of the air inlet and outlet ducts that are connected to the door body.

[0065] The above solution avoids the first fixing component affecting the normal exhaust of the air inlet and outlet ducts, thus improving the working stability of the auxiliary drying device.

[0066] Furthermore, the cross-sectional areas of the air inlet duct and the air outlet duct gradually increase in the direction away from the fan.

[0067] The above solution reduces air intake resistance and lowers the operating noise of the auxiliary drying device, while allowing the airflow to stay in the air outlet duct for a longer time and be heated more fully by the heating components, thus improving the heating efficiency of the auxiliary drying device.

[0075] In this embodiment, the side of the door with the observation window faces the inside of the dryer, and the air inlet and air outlet on the observation window are connected to the inside of the dryer.

[0076] The above solution enables the air in front of the dryer drum to be circulated and heated, thereby improving the drying speed of the dryer and the temperature consistency between the front and back sides of the dryer drum.

[0077] Example 6

[0078] As another embodiment of the present invention, this embodiment provides a clothes dryer, wherein the door of the clothes dryer is the clothes dryer door with auxiliary drying device described in Embodiment 3.

[0079] In this embodiment, the side of the door with the observation window faces the inside of the dryer, the air outlet on the observation window is connected to the inside of the dryer, and the air inlet is connected to the outside of the dryer.

[0080] The above method introduces air from outside the dryer into the door for heating before it is circulated into the dryer, thus avoiding the problem of water vapor remaining in the fan after heating the humid air inside the drum, which could affect the normal operation of the fan.
