Description

Technical Field

[0001] This invention relates to the field of dryer technology, and more particularly to a dryer door and a dryer. Background Technology

[0002] A clothes dryer is a household appliance that uses electric heating to instantly evaporate the moisture from washed clothes. Clothes dryers are now widely used in developed countries such as Europe and America. The main structure of a clothes dryer includes a drum, a circulating air duct, a casing, and a door. The circulating air duct includes an evaporator, a condenser, and a fan. The fan blows high-temperature gas into the drum, and as the drum rotates, it dries the clothes inside.

[0003] In existing technology, dryers typically have only one drum (also called a drying drum). When using a dryer to dry clothes, all clothes are placed into the drying drum together. After drying, clothes often become tangled, with larger items wrapping around smaller items. This can lead to deformation and incomplete drying, especially for the smaller items wrapped inside. Therefore, users need to separate large and small items for drying, resulting in longer drying times, wasted energy, and a poor user experience. Summary of the Invention

[0004] Based on the above, the purpose of this invention is to provide a dryer door and a dryer with dual drying drums, which separates the drying areas for large and small items of clothing, and dries both items simultaneously.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dryer door body, comprising:

[0007] The main door is hinged to the main body of the dryer;

[0008] The secondary door includes a first grid hole that communicates with a first drying drum in the main body of the dryer. The first grid hole is configured to be selectively opened or closed.

[0009] The drum wall has one end connected to the main door and the other end connected to the auxiliary door; a second grid hole is provided on the drum wall; the second grid hole is connected to the circulating air duct of the dryer body, and the second grid hole is configured to be selectively opened or closed;

[0010] The main door, the secondary door, and the inner wall together form the second drying tube.

[0011] As an alternative to the dryer door, the secondary door includes a filling blade located within a first grid hole and configured to rotate relative to the first grid hole to selectively open or close the first grid hole.

[0012] As an optional solution for the dryer door, the first grid holes are arranged in an array, with a rotating shaft in each row or column. The filling blades are fixedly connected to the rotating shaft so that the first grid holes in each row or column can be opened or closed independently.

[0013] As an optional solution for the dryer door, the secondary door also includes an electric drive device, which includes a motor and a lead screw. The motor drives the lead screw. One end of the rotating shaft includes a gear or a gear shaft segment. The lead screw meshes with the rotating shaft to enable all the first grid holes to open or close uniformly.

[0014] As an alternative to the dryer door, the secondary door has a first through hole on the surface near the drum wall, a roller on the surface away from the drum wall, and a second through hole at the position of the roller opposite the first through hole. The roller is configured to rotate with the axle so that the first and second through holes are selectively aligned or misaligned.

[0015] As an alternative to the dryer door, the projection of the second through hole on the surface of the secondary door near the drum wall can coincide with or completely cover the first through hole.

[0016] As an alternative to the dryer door, a clothes hanger is provided on the main door and / or drum wall, and the clothes hanger is located inside the second drying drum.

[0017] As an optional solution for the dryer door, the main door and the drum wall are integrally formed, and the secondary door is hinged to the drum wall.

[0018] As an optional solution for the dryer door, the secondary door and the drum wall are integrally formed, and the secondary door or drum wall is hinged to the main door.

[0019] A clothes dryer includes a clothes dryer body and a clothes dryer door as described in any of the above embodiments.

[0020] The beneficial effects of this invention are as follows:

[0021] This invention provides a dryer door, comprising a main door, a secondary door, and a drum wall. The main door is hinged to the dryer body, and opening the main door allows clothes to be placed into or removed from a first drying drum within the dryer body. The secondary door includes a first grid hole communicating with the first drying drum in the dryer body, and the first grid hole is configured to selectively open or close. One end of the drum wall is connected to the main door, and the other end is connected to the secondary door. The drum wall has a second grid hole. The main door, secondary door, and drum wall together form a second drying drum, which is used to store small items of clothing, separating large and small items to prevent small items from being wrapped by larger items and thus unable to dry.

[0022] When the second grid opening is open, the second drying drum is connected to the circulating air duct of the dryer body. When the second grid opening is closed, the second drying drum becomes an independent insulated space. When the first grid opening on the secondary door is open, the second drying drum is connected to the first drying drum in the dryer body. When both the first and second grid openings are open, part of the hot airflow for drying clothes passes through the first drying drum and directly enters the circulating air duct, while the other part passes through the first drying drum, enters the second drying drum through the first grid opening, and then enters the circulating air duct through the second grid opening. This allows large items in the first drying drum and small items in the second drying drum to be dried simultaneously, shortening the drying cycle, achieving energy savings, and improving the user experience.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Figure 1 This is a schematic diagram of a clothes dryer provided in a specific embodiment of the present invention. Figure 2 This is a schematic diagram of the dryer door in the open state according to a specific embodiment of the present invention, referring to... Figure 1 and Figure 2 This embodiment provides a dryer door and a dryer. The device includes a main door 1, a secondary door 2, and a drum wall 3. The main door 1 is hinged to the dryer body 100. After opening the main door 1, clothes can be placed into or removed from the first drying drum 110 in the dryer body 100. The main door 1 includes an outer surface and an inner surface. The inner surface of the main door is close to the dryer body 100, and the outer surface of the main door is away from the dryer body 100.

[0037] The secondary door 2 includes a first grid hole 21, which communicates with the first drying drum 110 in the dryer body 100. The first grid hole 21 is configured to be selectively opened or closed.

[0038] Figure 3 This is a schematic diagram of the dryer door in the closed state according to a specific embodiment of the present invention, with reference to... Figure 3 One end of the cylinder wall 3 is connected to the inner surface of the main door 1, and the other end of the cylinder wall 3 is connected to the auxiliary door 2. The cylinder wall 3 is provided with a second grid hole, which is connected to the circulating air duct 120 of the dryer body 100. The second grid hole is configured to be selectively opened or closed.

[0039] The main door 1, the secondary door 2, and the drum wall 3 together form the second drying drum. The second drying drum is used to store small items of clothing, separating large and small items to prevent small items from being wrapped up by larger items and unable to dry. When the second grid opening is open, the second drying drum is connected to the circulating air duct 120 of the dryer body 100. When the second grid opening is closed, the second drying drum becomes an independent insulated space. When the first grid opening 21 on the secondary door 2 is open, the second drying drum is connected to the first drying drum 110 in the dryer body 100. When both the first grid hole 21 and the second grid hole are open, part of the hot airflow for drying clothes passes through the first drying drum 110 and directly enters the circulating air duct 120, while the other part passes through the first drying drum 110 and enters the second drying drum through the first grid hole 21, and then enters the circulating air duct 120 through the second grid hole. This allows large items of clothing in the first drying drum 110 and small items of clothing in the second drying drum to be dried simultaneously, shortening the drying cycle, achieving energy-saving effects, and improving the user experience.

[0040] Specifically, in this embodiment, the first grid holes 21 are arranged in an array. Preferably, the first grid holes 21 are arranged in multiple rows with equal spacing. Each row of the first grid holes 21 is provided with a rotating shaft. The secondary door 2 also includes filling blades 22, which are located inside the first grid holes 21 and fixedly connected to the rotating shaft. When the rotating shaft rotates, it drives the filling blades 22 to rotate relative to the first grid holes 21, so that each row of the first grid holes 21 can be opened or closed independently. More specifically, the filling blades 22 are rectangular blades, and through holes are provided on the axis of the rectangular blade along its length. The through holes are connected to the rotating shaft, so that the filling blades 22 are connected to the first grid holes 21.

[0041] In existing technologies, variable frequency fans are typically used to change the total air intake, thereby affecting the drying speed of clothes inside the dryer drum. Compared to existing technologies, the dryer door provided in this embodiment can control the total air intake of the second drying drum by changing the rotation angle of the filling blades 22, thereby adjusting the drying speed of clothes inside the second drying drum.

[0042] As a preferred technical solution, the secondary door 2 also includes an electric drive device, which comprises a motor and a lead screw, with the motor driving the lead screw. One end of the rotating shaft includes a gear or gear shaft segment, and the lead screw meshes with the gear or gear shaft segment on the rotating shaft, thereby realizing the electric drive of the filling blades 22. This facilitates the automatic control of the filling blades 22, allowing them to rotate according to the time and angle set in the drying program, achieving selective opening or closing. More preferably, in this embodiment, there are multiple rows of first grid holes 21, and the multiple rows are evenly spaced. According to actual usage needs, the gears or gear shaft segments on multiple rotating shafts can be arranged on the same side, so that the lead screw can simultaneously mesh with multiple rotating shafts, realizing the unified opening or closing of all first grid holes 21.

[0043] In existing technologies, variable frequency fans are typically used to change the total air intake, thereby affecting the drying speed of clothes inside the dryer drum. Compared to existing technologies, the dryer door provided in this embodiment can control the total air intake of the second drying drum by changing the rotation angle of the filling blades 22, thereby adjusting the drying speed of clothes inside the second drying drum.

[0044] More specifically, in this embodiment, the second grid hole is connected to the circulation duct 120 of the dryer body 100. Preferably, the second grid hole is directly opposite the circulation duct 120 of the dryer body 100. More preferably, the second grid hole has the same structure as the first grid hole 21, which will not be described in detail here. It should be noted that in some embodiments, the second grid hole can also be replaced by a perforated through hole. The perforated through hole can be considered as a normally open second grid hole, so it can ensure that the second grid hole is connected to the circulation duct 120 of the dryer body 100. However, the perforated through hole cannot be closed, so the second drying drum cannot be sealed as an independent heat preservation space.

[0045] As a preferred technical solution, a clothes hanger 4 is provided on the inner surface of the main door 1 and / or the cylinder wall 3, and the clothes hanger 4 is located inside the second drying cylinder. In this embodiment, the clothes hanger 4 is a horizontal clothes drying rack or hook, which is convenient for placing small items of clothing, especially suitable for underwear, socks, etc.

[0046] As a preferred technical solution, the main door 1 and the cylindrical wall 3 are integrally formed, and the secondary door 2 is hinged to the cylindrical wall 3.

[0047] As a preferred technical solution, the secondary door 2 and the cylindrical wall 3 are integrally formed, and the secondary door 2 or the cylindrical wall 3 is hinged to the main door 1.

[0048] Example 2

[0049] The basic structure of the dryer door provided in this embodiment is the same as that in Embodiment 1, with only some structural differences. This embodiment only describes the structures that differ from those in Embodiment 1. Figure 4 This is a schematic diagram of the dryer door in the open state according to a specific embodiment two of the present invention. Figure 4 As shown.

[0050] As a preferred technical solution, the secondary door 2 has a first through hole on its surface near the cylinder wall 3. In this embodiment, the shape of the first through hole is not limited; for example, a round hole, a square hole, or an irregular hole are all applicable. The first through holes are evenly distributed on the surface of the secondary door 2 near the cylinder wall 3 so that the air passing through the first through holes can be evenly blown to all areas inside the second drying drum.

[0051] A rotating wheel 23 is provided on the surface of the secondary door 2 away from the cylinder wall 3. A second through hole is located at the position of the rotating wheel 23 directly opposite the first through hole, and the remaining positions are closed solids. The rotating wheel 23 can rotate with the axle located at the center of the rotating wheel 23, so that the second through hole is directly opposite the first through hole or misaligned with the first through hole 21. When the second through hole is directly opposite the first through hole, the second drying drum is connected to the first drying drum 110, realizing simultaneous drying of the second drying drum, the first drying drum 110, and the clothes; when the second through hole is misaligned with the first through hole, the second drying drum is separated from the first drying drum 110. At this time, the second drying drum can be used as an independent storage space.

[0052] In some embodiments, a handwheel is connected to one end of the axle of the rotating wheel 23. Rotating the handwheel controls the opening and closing degree of the first and second through holes, thereby controlling the airflow inside the second drying drum. When the first through hole is directly opposite the second through hole, the opening and closing degree is the largest, and the ventilation volume is also the largest. When the first and second through holes are completely misaligned, the opening and closing degree is the smallest, and the ventilation volume is zero.

[0053] As a preferred technical solution, the projection of the second through hole on the surface of the secondary door 2 near the cylinder wall 3 can coincide with or completely cover the first through hole. This arrangement allows control of the maximum airflow of the second drying drum via the diameter of the first through hole, and adjustment of the airflow between zero and maximum airflow via the degree of opening and closing of the second and first through holes.

[0054] In other embodiments, one end of the axle of the wheel 23 is connected to an electric drive device to realize the electric drive of the wheel 23, which is beneficial to realize the automatic control of the wheel 23.

Therefore, it possesses the beneficial effects of the dryer door as described in any of the above embodiments. The dryer body 100 includes a first drying drum 110, a circulation duct 120, and a housing 130. The circulation duct 120 includes an evaporator 121, a condenser 122, and a fan 123. High-temperature gas is blown into the first and second drying drums by the fan 123 to dry the clothes inside the drums.
