Abstract
Description
Technical Field
[0001] The present application relates to the technical field of clothes dryers, and in particular to a clothes dryer host. Background Art
[0002] At present, the dryers on the market are cleaning household appliances that evaporate the moisture in clothes instantly by blowing hot air into the clothes cover. They are suitable for daily washing, care and drying, and are especially suitable for use in humid areas or in weather such as haze and rainy seasons.
[0003] In the existing clothes dryer, the main dryer is arranged at the bottom, and the clothes to be dried placed in the clothes cover are located above the main dryer. The main dryer draws the air with lower outside temperature into the air duct, and then the lower temperature air is heated by the heating element to form hot air and blown upward. The hot air blows toward the clothes to be dried to gradually dry them, and the hot air is finally discharged from the exhaust holes on the clothes cover.
[0004] At present, most of the clothes dryer main units are large in size. Although they can be disassembled and installed, the installation steps are cumbersome, and they take up a large space after installation. It is difficult to store them after disassembly, which is difficult to meet the current requirements of fast drying and portability and space saving. For this reason, some clothes dryer main units adopt a foldable body structure, which can reduce the storage volume when folded and increase the drying capacity when unfolded, solving the contradiction between large drying capacity and small storage volume in the existing technology.
[0005] However, during the folding or unfolding process of the dryer main unit, the wires inside the dryer main unit will also be pulled with the movement of the dryer main unit, causing the wires inside the dryer main unit to stretch or contract, and further causing problems such as wire clamping, wire hanging, wire cutting, and wire stretching. Not only will the wires be easily damaged, but the wires will also affect the rotation of the dryer main unit, resulting in the dryer main unit being unable to rotate to the unfolded state or unable to return to the folded state. Summary of the invention
[0006] Based on this, it is necessary to provide a clothes dryer host to address the problem that the wires inside the clothes dryer host will be pulled as the body moves, thereby causing the wires inside the clothes dryer host to stretch or shrink.

[0050] See also Figure 1 and Figure 2 A clothes drying main unit provided in one embodiment of the present application includes a fixed body 10 and a movable body 30. The movable body 30 is movably connected to the fixed body 10 so that the movable body 30 can move relative to the fixed body 10, thereby realizing the unfolding and folding of the body.
[0051] Specifically, the movable body 30 is rotatable relative to the fixed body 10 around a rotation axis, and a movable air outlet 42 is formed on the movable body 30. When the movable body 30 and the fixed body 10 are completely folded, as shown in FIG. Figure 1 As shown, the movable air outlet 42 is located between the movable body 30 and the fixed body 10. In this way, after the clothes dryer main unit is folded, not only can the space be reduced, but the movable air outlet 42 can also be closed to prevent external dust and debris from entering the movable air outlet 42 and causing blockage, thereby affecting the air outlet effect.
[0052] When the movable body 30 rotates a certain angle relative to the fixed body 10, the clothes dryer can be in an unfolded state. Figure 2 As the active clothes dryer moves relative to the fixed body 10, the direction of the active air outlet 42 changes with the movement of the active clothes dryer, and when the clothes dryer is in a fully unfolded state, that is, Figure 2 In the state of the clothes dryer main unit shown, the clothes dryer main unit is placed on a horizontal plane, and the movable air outlet 42 is oriented in a vertical direction.
[0053] In actual use of the dryer, the fully unfolded dryer main unit is arranged under the clothes cover of the dryer, so that the movable air outlet 42 can be directed toward the clothes hung on the clothes cover, so that the hot air discharged through the movable air outlet 42 can dry the clothes on the clothes cover.
[0054] Please see Figure 5 and Figure 6 In order to enable the active air outlet 42 to discharge hot air, an active heating element 41 and components such as an active blower are provided on the active body 30 to generate airflow through the active blower. After the airflow passes through the active heating element 41, it is heated to form hot air, and the hot air is discharged from the active air outlet 42.
[0055] In order to supply power to the movable heating element 41 and the movable blower, a power supply module 21 is provided on the fixed body 10, and the power supply module 21 is used to connect to an external power source such as a power grid. In addition, the power supply module 21 is also electrically connected to the movable heating element 41 and the blower motor for driving the movable blower, so that the power of the power grid is distributed to the movable heating element 41 and the blower motor through the power supply module 21.
[0056] Among them, the blower motor is arranged on the fixed body 10 and is connected to the movable blower on the movable body 30 through a transmission shaft. The transmission shaft can move relative to the fixed body 10 with the movement of the movable body 30, so that after the movable body 30 moves relative to the fixed body 10, the transmission shaft can also realize the driving of the movable blower by the blower motor.
[0057] It should be noted that the transmission shaft can move relative to the fixed body 10 along with the movement of the movable body 30, which means that the transmission shaft can adapt to the movement of the movable body 30 relative to the fixed body 10 to ensure the transmission connection between the blower motor and the movable blower. Figure 2 In the embodiment of the present invention, the movable body 30 is rotatably disposed on the fixed body 10 around a rotation axis, and the axis of the transmission shaft is coaxial with the rotation axis, so that when the movable body 30 rotates relative to the fixed body 10, the transmission shaft can also rotate together to adapt to the position of the movable body 30. In other embodiments, when the movable body 30 is disposed on the fixed body 10 in a telescopic manner, the transmission shaft can be telescopic relative to the fixed body 10 together with the movable body 30.
[0058] The movable heating element 41 is arranged on the movable body 30. If it is directly connected to the power supply module 21 and the movable heating element 41 through a wire, then when the movable body 30 moves relative to the fixed body 10, the movable heating element 41 will drive the wire to move together, thereby causing various problems such as wire clamping, wire hanging, wire cutting, and wire stretching. Not only will it easily cause the wire to be damaged, but the wire will also affect the rotation of the movable body 30, resulting in the dryer main unit being unable to rotate to the unfolded state or unable to return to the folded state.
[0059] For this purpose, see Figure 3 and Figure 4 The fixed body 10 has a fixed contact 11; the movable body 30 has a movable contact 31; during the movement of the movable body 30 relative to the fixed body 10, it has an unfolded position and a folded position. When the movable body 30 is in the unfolded position, the movable contact 31 contacts with the fixed contact 11, and the two are electrically connected to each other. When the movable body 30 is in the folded position, the movable contact 31 is separated from the fixed contact 11.
[0060] Among them, the movable heating element 41 is electrically connected to the movable contact 31, and the power supply module 21 is electrically connected to the fixed contact 11. In this way, when the movable body 30 moves to the unfolded position relative to the fixed body 10, the movable contact 31 is electrically connected to the fixed contact 11, and the power supply module 21 and the movable heating element 41 are electrically connected to each other. At this time, the movable heating element 41 starts to work, and the wind blown out of the movable air outlet 42 is hot air.
[0061] When the movable body 30 moves to the folded position relative to the fixed body 10, the movable contact 31 is disconnected from the contacts, the power supply module 21 is disconnected from the movable heating element 41, the movable heating element 41 stops working, and the wind blown out of the movable air outlet 42 is cold wind.
[0062] In this way, through the electrical connection between the movable contact 31 and the fixed contact 11, only when the user unfolds the clothes dryer, the movable heating element 41 will start to work, and the movable air outlet 42 will blow out hot air for drying clothes. When the user rotates the movable body 30, that is, when the user needs to start folding the clothes dryer, the movable contact 31 will separate from the fixed contact 11, so that the wind blown out of the movable air outlet 42 is only natural wind, so as to avoid the hot air affecting the clothes dryer or the user due to the change in the position of the movable air outlet 42 after folding.
[0063] Since the movable body 30 and the fixed body 10 are electrically connected to each other through the movable contact 31 and the fixed contact 11, when the movable body 30 rotates relative to the fixed body 10, the wires inside the movable body 30 and the fixed body 10 will remain stationary relative to themselves and will not be affected by the movement of the movable body 30, thereby avoiding various problems such as wire clamping, wire hanging, wire cutting, and wire stretching, thereby ensuring the normal movement of the movable body 30 relative to the fixed body 10 and improving the service life of the dryer main unit.
[0064] It is understandable that the above-mentioned movable contact 31 can be but is not limited to being connected to the movable heating element 41, and the fixed contact 11 can be but is not limited to being connected to the power supply module 21. As in other embodiments, the blower motor can also be arranged on the movable body 30, and the blower motor is electrically connected to the movable contact 31, so that when the movable body 30 moves to the unfolded state, the blower motor can be electrically connected to the power supply module 21, and the movable air outlet 42 can output airflow. When the movable body 30 moves to the folded position, the blower motor is disconnected from the power supply module 21, and the movable air outlet 42 stops outputting airflow. That is, in this embodiment, when the dryer main unit is unfolded, the movable air outlet 42 automatically discharges air, and when the dryer is folded, the movable air outlet 42 is automatically closed.
[0065] In some embodiments of the present application, refer to Figure 8 and Fig. 9 The fixed contacts 11 include a plurality of movable contacts 31 arranged at intervals along a first direction, and the first direction intersects with the direction of movement of the movable body 30 relative to the fixed body 10. Figure 5 In the embodiment, the moving direction of the movable body 30 relative to the fixed body 10 is the circumferential direction around the rotation axis, and the first direction is the radial direction. The movable contacts 31 include a plurality of movable contacts 31. When the movable body 30 is in the unfolded position, each movable contact 31 contacts one of the fixed contacts 11. When the movable body 30 is in the folded position, each movable contact 31 is separated from all the fixed contacts 11.
[0066] During actual use, the movable heating element 41 has a positive electrode connector and a negative electrode connector, and both the positive electrode connector and the negative electrode connector need to be electrically connected to the power supply module 21. To this end, the positive electrode connector and the negative electrode connector can respectively contact one of the movable contacts 31, and the positive electrode connector and the negative electrode connector are electrically connected to the power supply module 21 through two movable contacts 31 and two fixed contacts 11.
[0067] Specifically, all the fixed contacts 11 include a first fixed contact 12 and a second fixed contact 13, and all the movable contacts 31 include a first movable contact 32 and a second movable contact 33. When the movable body 30 is in the expanded position, the first fixed contact 12 contacts the first movable contact 32, and the second fixed contact 13 contacts the second movable contact 33.
[0068] The movable body 30 includes a movable heating element 41, which includes a positive terminal and a negative terminal. The positive terminal is electrically connected to the first movable contact 32, and the negative terminal is electrically connected to the second movable contact 33. The fixed body 10 includes a power supply module 21, and the power supply module 21 has an X1 power supply terminal and a neutral terminal. The X1 power supply terminal is electrically connected to the first fixed contact 12, and the neutral terminal is electrically connected to the second fixed contact 13.
[0069] Among them, the X1 power supply terminal is used to connect to the live wire of the external power grid, and the neutral wire terminal is used to connect to the neutral wire of the external power grid. When the movable body 30 is in the unfolded position, the current of the live wire is input to the first fixed contact 12 through the X1 power supply terminal, and the first fixed contact 12 inputs the current to the first movable contact 32, and finally the current is input to the movable heating element 41 through the first movable contact 32 to drive the movable heating element 41 to generate heat. After the current passes through the movable heating element 41, it will pass through the second movable contact 33, the first fixed contact 12, the neutral wire terminal in sequence, and finally return to the neutral wire to complete the closed loop of the circuit.
[0070] In some embodiments, all the fixed contacts 11 further include a third fixed contact 14, and the power supply module 21 further includes an X2 power supply terminal, which can also be connected to the live wire of the external power grid. All the movable contacts 31 further include a third movable contact 34, and when the movable body 30 is in the unfolded position, the third fixed contact 14 contacts the third movable contact 34. The movable body 30 includes two movable heating elements 41, wherein the positive terminal of one movable heating element 41 is electrically connected to the first movable contact 32, the positive terminal of the other heating element is electrically connected to the third movable contact 34, and the negative terminal of each movable heating element 41 is electrically connected to the second movable contact 33.
[0071] In this way, when the movable body 30 is located in the unfolded position, the two movable heating elements 41 can simultaneously input the airflow of the movable air outlet 42 for heating, so that the temperature of the airflow discharged from the movable air outlet 42 is higher, thereby effectively improving the drying efficiency of the clothes.
[0072] It should be noted that the movable body 30 includes two movable heating elements 41, which means that the movable body 30 has at least two movable heating elements 41, that is, the number of movable heating elements 41 can also be three, four or more. In addition, the plurality of movable contacts 31 can also include a fourth movable contact 31 and a fifth movable contact 31, and the plurality of fixed contacts 11 can also include a fourth fixed contact 11 and a fifth fixed contact 11, so that the third and fourth movable heating elements 41 can also be electrically connected to the power supply module 21 through one of the movable contacts 31 and the fixed movable contact 31.
[0073] In some embodiments of the present application, the movable body 30 has a movable air outlet 42, and the fixed body 10 has a fixed air outlet 23. When the movable body 30 is in the unfolded position, the fixed air outlet 23 is parallel to the movable air outlet 42. That is, when the movable body 30 is in the unfolded position, the fixed air outlet 23 and the movable air outlet 42 are both oriented in the vertical direction, so that when the clothes drying host is used to dry clothes, the clothes can be dried by the fixed air outlet 23 and the movable air outlet 42 simultaneously, thereby improving the range and efficiency of clothes drying.
[0074] In order to make the wind blown out of the fixed air outlet 23 hot wind, a fixed heating element 22 is also provided on the fixed body 10. The fixed heating element 22 also has a positive terminal and a negative terminal. The positive terminal of the fixed heating element 22 is directly electrically connected to the X1 power supply terminal or the X2 power supply terminal of the power supply module 21, and the negative terminal is electrically connected to the neutral terminal. Since the fixed heating element 22 is provided on the fixed body 10, the movement of the movable body 30 will not affect the connection between the fixed heating element 22 and the power supply module 21.
[0075] Furthermore, the fixed heating elements 22 also include two, wherein the positive pole connector of one fixed heating element 22 is electrically connected to the X1 power supply terminal, the positive pole connector of the other fixed heating element 22 is electrically connected to the X2 power supply terminal, and the negative pole connector of each fixed heating element 22 is electrically connected to the neutral terminal, thereby increasing the hot air temperature of the fixed air outlet 23 through the two fixed heating elements 22.
[0076] In some embodiments of the present application, the fixed body 10 includes a fixed shell 20 and a fixed contact spring 15 installed on the fixed shell 20, and a fixed contact 11 is formed on the fixed contact spring 15. When the movable body 30 is in the expanded position, the fixed contact spring 15 is pressed between the fixed shell 20 and the movable contact 31.
[0077] In this way, when the movable body 30 is in the expanded position, the fixed contact spring 15 will be compressed, so that the fixed contact spring 15 can form a stable contact with the movable contact 31 through the elastic force of the fixed contact spring 15 itself, ensuring that the movable heating element 41 and the power supply module 21 can achieve a stable electrical connection.
[0078] Furthermore, the movable body 30 includes a movable shell 40 and a movable contact spring 35 installed on the movable shell 40, and a movable contact 31 is formed on the movable contact spring 35. When the movable body 30 is in the expanded position, the movable contact spring 35 is pressed between the movable shell 40 and the fixed contact 11, so as to achieve a stable electrical connection between the movable heating element 41 and the power supply module 21 through the contact between the movable contact spring 35 and the fixed contact spring 15.
[0079] It is understandable that the movable contact spring 35 and the fixed contact spring 15 can be required, and only one of them can be set. For example, only the fixed contact spring 15 is set, and the movable contact 31 is directly formed and set on the outer surface of the movable shell 40. Only the fixed contact spring 15 can complete the stable connection between the fixed contact 11 and the movable contact 31.
[0080] Specifically, in some embodiments, a guide groove 24 is provided on the fixed housing 20, and a guide portion 43 is provided on the movable housing 40. When the movable body 30 moves relative to the fixed body 10, the guide portion 43 can move along the guide groove 24, so that the movable body 30 can move relative to the fixed body 10 in a specified direction through the guiding effect of the guide groove 24 on the guide portion 43. When the movable body 30 rotates around a rotation axis of the fixed body 10, the guide portion 43 and the guide groove 24 are both semicircular arc structures, so that the dryer body can switch between the two states of 180° expansion and closure.
[0081] Among them, the fixed contact 11 is located on the inner wall of the guide groove 24, and the movable contact 31 is located on the guide portion 43. In this way, when the movable body 30 moves relative to the fixed body 10, the guide portion 43 will move in the guide groove 24, thereby driving the movable contact 31 to move relative to the fixed contact 11 until the movable body 30 moves to the expanded position and the movable contact 31 abuts against the fixed contact 11.
[0082] It is understandable that in some other embodiments, a guide portion 43 may be provided on the fixed shell 20 and a guide groove 24 may be provided on the movable body 30 , and the fixed contact 11 is located on the guide portion 43 and the movable contact 31 is located on the inner wall of the guide groove 24 .
[0083] Further, see Figure 7 and Fig.10 The fixed body 10 further includes a fixed mounting seat 16, on which a plurality of fixed elastic contact pieces are arranged, and each fixed elastic contact piece is formed with a fixed contact 11. A fixed mounting hole 17 is opened on the inner wall of the guide groove 24, and the fixed mounting seat 16 is penetrated through the fixed mounting hole 17, so that each fixed elastic contact piece can extend into the guide groove 24, and then the fixed contact 11 can abut against the fixed contact 11 on the guide portion 43.
[0084] Furthermore, the movable body 30 further includes a movable mounting seat 36, on which a plurality of movable elastic contact pieces are arranged, and each movable elastic contact piece is formed with a movable contact point 31. A movable mounting hole 37 is opened on the inner wall of the guide groove 24, and the movable mounting seat 36 is penetrated through the movable mounting hole 37, so that each movable elastic contact piece protrudes from the guide portion 43, and further enables the movable contact point 31 to abut against the movable contact point 31 on the inner wall of the guide groove 24.
[0085] Specifically, in some embodiments, the guide groove 24 has an opening 25 at one end in its longitudinal direction, and when the movable body 30 moves from the unfolded position to the folded position relative to the fixed body 10, at least part of the guide portion 43 can leave the guide groove 24 through the opening 25. In actual use, as long as part of the guide portion 43 is located in the guide groove 24, the guide groove 24 can guide the guide portion 43, so while ensuring the guiding effect, the length of the guide groove 24 can be reduced, thereby reducing the volume of the fixed housing 20.
[0086] Specifically, see Figure 5 When the movable body 30 moves counterclockwise relative to the fixed body 10, the guide groove 24 remains stationary, and the guide portion 43 moves clockwise in the guide groove 24. When the movable body 30 is in the unfolded position, the opening 25 is provided at one end of the guide groove 24 facing the movable body 30, and when the guide portion 43 moves clockwise in the guide groove 24, the guide portion 43 will leave the guide groove 24 from the opening 25 until the guide portion 43 completely leaves the guide groove 24, or the movable body 30 moves to the folded position and cannot move further.
[0087] In order to ensure the reliability of contact between the fixed contact 11 and the movable contact 31, the thickness of the movable elastic contact protruding from the outer surface of the guide portion 43 is greater than half of the gap between the guide groove 24 and the outer surface of the guide portion 43, and the thickness of the fixed elastic contact protruding from the inner wall of the fixed groove is greater than half of the gap between the outer surface of the guide portion 43.
[0088] In actual use, the inner wall of the guide groove 24 is a smooth surface, and the surface of the guide portion 43 is also protruded with a reinforcing rib 44 to avoid mutual interference between the reinforcing rib 44 and the fixed elastic contact piece. In some embodiments, when the movable body 30 is in the unfolded position, all the guide portions 43 are located in the guide groove 24, the fixed contact 11 is located at the end of the guide groove 24 away from the opening 25, the movable contact 31 is located at the end of the guide portion 43 away from the opening 25, and the reinforcing rib 44 is located on the side of the movable contact 31 from the unfolded position to the folded position, that is, the reinforcing rib 44 is located on the side of the movable contact 31 facing the opening 25.
[0089] In this way, when the movable body 30 moves from the unfolded position to the folded position relative to the fixed body 10, the movable contact 31 and the reinforcing rib 44 will move toward the opening 25 together, that is, the movable contact 31 and the reinforcing rib 44 will move away from the fixed contact 11 together, and the reinforcing rib 44 will not come into contact with the fixed contact 11, thereby avoiding the problem of friction between the reinforcing rib 44 and the fixed contact 11, which affects the conductivity and contact efficiency of the fixed contact 11.
[0090] The above-mentioned clothes drying host has at least the following advantages:
[0091] Since the movable body 30 and the fixed body 10 are electrically connected to each other via the movable contact 31 and the fixed contact 11, when the movable body 30 rotates relative to the fixed body 10, the wires inside the movable body 30 and the fixed body 10 will remain stationary relative to themselves and will not be affected by the movement of the movable body 30, thereby avoiding various problems such as wire clamping, wire hanging, wire cutting, and wire stretching, thereby ensuring the normal movement of the movable body 30 relative to the fixed body 10 and improving the service life of the dryer main unit.
[0092] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
