Description

Technical Field

[0001] The present application relates to the technical field of clothes dryers, and in particular to a heating structure and a household appliance. 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, a heating element is usually set in the air duct of the clothes dryer, and the heat generated by the heating element is used to heat the air flow in the air duct, so that hot air can be blown out from the air duct outlet. In actual use, if there are a large number of clothes to be dried or the clothes are thick, hot air with a higher temperature and faster flow rate will be required to meet the user's drying needs. At this time, a single heating element is often not enough to meet the user's demand for the power of the clothes dryer.

[0005] For this reason, some clothes dryers are equipped with multiple heating elements in the main unit to increase the power of the clothes dryer. However, when users choose clothes dryers, they often do not know how much power they need. Once users choose a clothes dryer with a single heating element, but the power of the clothes dryer cannot meet the user's usage needs, the user can only repurchase or replace a clothes dryer with a higher power, resulting in a waste of money and time costs for users.

[0060] See also Figure 1 A household appliance provided in one embodiment of the present application includes a heating structure, on which an active air outlet 320 is formed. In order to enable the heating structure to output hot air from the active air outlet 320, the heating structure also includes an active heating element 131. The active heating element 131 is used to heat the airflow passing through it. The heated airflow forms hot air and is discharged from the active air outlet 320 to meet the user's demand for hot air.

[0061] In actual use, household appliances often have multiple configurations according to different user needs. For example, in addition to the movable heating element 131, the household appliance is also provided with a fixed heating element, which can heat the same airflow with the movable heating element 131, thereby increasing the maximum temperature of the airflow and outputting a higher temperature. The fixed heating element and the movable heating element 131 can also be used to heat the two airflows respectively, thereby increasing the coverage of the hot air through the two airflows.

[0062] Therefore, the household appliance will have two configuration options, one is a low-power configuration with only the movable heating element 131, and the other is a high-power configuration with both the movable heating element 131 and the fixed heating element. When purchasing the household appliance, users often do not know which configuration they need to choose. Once the user chooses the low-power configuration, the configuration cannot meet the user's practical needs, and the user can only purchase it again or return it, resulting in a waste of money and time costs for the user.

[0063] For this purpose, see Figure 2 , Figure 3 and Figure 4 The heating structure also includes a first air duct member 110, a second air duct member 120, and a channel assembly 140. The first air duct member 110 is connected to the active air outlet 320 at one end in its longitudinal direction, and has the active air outlet 320 at the other end. The second air duct member 120 has a second air duct opening 121 at one end in its longitudinal direction, and is connected to an air outlet member such as a blower that can output airflow at the other end. The second air duct opening 121 and the first air duct opening 111 are arranged at intervals along the first direction X, and an installation position 130 is formed between the two.

[0064] The channel assembly 140 is movably mounted on at least one of the first air duct member 110 and the second air duct member 120, and the channel assembly 140 includes a folded state and a conducting state. When the channel assembly 140 is in the folded state, refer to Figure 4 , Figure 5 The channel assembly 140 is avoided in the installation position 130, and the movable heating element 131 is detachably arranged in the installation position 130. Since the channel assembly 140 is avoided in the installation position 130 when the channel assembly 140 is in the folded state, the channel assembly 140 will not affect the installation of the movable heating element 131 in the installation position 130. Moreover, when the movable heating element 131 is located in the installation position 130, the movable heating element 131 is connected to the first air duct opening 111 and the second air duct opening 121.

[0065] Specifically, the first heating element includes a heating shell and a heating body, the heating shell is formed with a heating channel, the heating body is arranged in the heating channel, and when the first heating element is arranged on the installation position 130, the heating channel is connected to the first air duct opening 111 and the second air duct opening 121. In this way, when the movable heating element 131 is located at the installation position 130, the airflow output by the air outlet element will pass through the second air duct element 120, the movable heating element 131 and the first air duct element 110, and the airflow will be heated by the movable heating body in the process of passing through the movable heating element 131, and finally discharged from the movable air outlet 320 on the first air duct element 110.

[0066] When the movable heating element 131 is detached from the mounting position 130, see Figure 6 , Figure 7 and Figure 8 , and when the channel assembly 140 is in the conducting state, the channel assembly 140 is connected to the first air duct opening 111 and the second air duct opening 121. At this time, the airflow output by the air outlet member passes through the second air duct member 120, the channel assembly 140 and the first air duct member 110, and finally is discharged from the active air outlet 320. That is, after the active heating member 131 is detached from the mounting position 130, the channel assembly 140 can also ensure the normal conduction between the first air duct member 110 and the second air duct member 120, thereby ensuring the normal air outlet of the active air outlet 320.

[0067] Specifically, when the household appliance is a clothes dryer, if the user selects a configuration without the active heating element 131, the channel assembly 140 is in a conducting state, and the first air duct member 110 and the second air duct member 120 are interconnected, that is, the clothes dryer can work normally without the active heating element 131. When the user is dissatisfied with the current configuration and needs to upgrade to a configuration with an active heating element 131, the user only needs to turn the channel assembly 140 to a folded state and install the active heating element 131 into the installation position 130, thereby realizing the customization of the heating power of the clothes dryer. The user does not need to repurchase or return the entire clothes dryer, but only needs to purchase the active heating element 131 separately to complete the upgrade of the clothes dryer power.

[0068] Among them, the household appliance can be a device that can output hot air, such as a heater, a clothes dryer, an air conditioner, etc., and according to the type of household appliance, the household appliance can also be provided with only one heating element, the active heating element 131, and another configuration is a configuration that does not have any heating element and outputs cold air alone. For example, in some embodiments, the household appliance is a fan, and the fan includes two configurations of warm air and cold air. When the active heating element 131 is set in the air outlet structure of the fan, the fan is a warm fan to blow out warm air, so as to be used for heating by the user. When the active heating element 131 is detached from the air outlet structure of the fan, the fan is a cold fan to blow out natural wind, so as to be used for cooling the user. The user can disassemble and assemble the active heating element 131 to switch the fan between a warm fan and a cold fan, so as to achieve customized functions.

[0069] In some embodiments of the present application, the household appliance includes a first air outlet mechanism 340 and a second air outlet mechanism 350, and at least one of the first air outlet mechanism 340 and the second air outlet mechanism 350 includes the above-mentioned heating structure, that is, the first air outlet mechanism 340 can include a heating structure, and the second air outlet mechanism 350 can be an ordinary air outlet structure, or both the first air outlet mechanism 340 and the second air outlet mechanism 350 can include the above-mentioned heating structure.

[0070] Among them, the common air outlet structure refers to a channel component 140 that does not have a switchable state, that is, the common air outlet structure cannot install a heating element by switching the state of the channel component 140. In this way, when the first air outlet mechanism 340 is the above heating structure and the second air outlet mechanism 350 is a common heating structure, the second air outlet mechanism 350 is used as a basic configuration, that is, the second air outlet mechanism 350 is used to ensure that the household appliance can output hot air or cold air at a certain power, and the user decides whether to upgrade the power of the household appliance according to whether the active heating element 131 is installed.

[0071] Specifically, when the household appliance is a clothes dryer main unit, the first air outlet mechanism 340 in the clothes dryer main unit is the above-mentioned heating structure, and the second air outlet mechanism 350 is a traditional air outlet structure. The first air outlet mechanism 340 is provided with the above-mentioned movable air outlet 320, and the second air outlet mechanism 350 is provided with a fixed air duct member and a fixed heating member. The fixed heating member is arranged in the fixed air duct member, and a fixed air outlet 330 is formed at one end of the fixed air duct member. The fixed heating member is used to heat the airflow in the fixed air duct, and the formed hot air is blown out from the fixed air outlet 330.

[0072] When the clothes that the user needs to dry are thin and in small quantity, and the demand for the dryer host is not great, the user can choose a dryer host that is not equipped with the movable heating element 131. At this time, the fixed air outlet 330 blows out hot air, thereby drying the clothes with the hot air, while the movable air outlet 320 blows out cold air. The cold air blown out by the movable air outlet 320 can be used to merge with the hot air from the fixed air outlet 330, thereby increasing the overall air volume of the dryer host and accelerating the drying speed of the dryer host.

[0073] When the user does not install the clothes dryer with the active heating element 131 for a period of time, as the weather gets colder, the clothes that the user needs to dry become thicker and the number of clothes increases, and the user will then have a higher demand for the power of the clothes dryer. At this time, the user can choose to purchase the active heating element 131 separately, and switch the channel assembly 140 in the first air outlet mechanism 340 to the folded state, so as to install the active heating element 131 into the first air outlet mechanism 340.

[0074] In this way, when the first air outlet mechanism 340 is installed with the movable heating element 131, the drying power of the dryer main unit is improved, and the wind blown out of the movable air outlet 320 is also hot air, so that the two hot airs pass through the movable air outlet 320 and the fixed air outlet 330, and the clothes are dried at the same time, which greatly improves the drying speed.

[0075] In some embodiments, the clothes drying host includes a fixed body 300 and a movable body 310, the movable body 310 is movable relative to the fixed body 300, the movable body 310 is provided with a first air outlet mechanism 340, and the fixed body 300 is provided with a second air outlet mechanism 350. The fixed body 300 is also provided with a power supply module to supply power to the movable heating element 131 and the fixed heating element.

[0076] During actual use, the movable body 310 is movable relative to the fixed body 300 so that the dryer main unit can be folded and unfolded. When the dryer main unit is folded, the movable air outlet 320 and the fixed air outlet 330 are both located inside the dryer main unit, thereby facilitating the storage of the dryer main unit. When the dryer main unit is unfolded, the movable air outlet 320 and the fixed air outlet 330 can both face the vertical direction to dry the clothes located above the dryer main unit.

[0077] In which, during the movement of the movable body 310 relative to the fixed body 300, the movable heating element 131 will move with the movable body 310, so that the connecting wires between the power supply module and the movable heating element 131 will move with the movable heating element 131, resulting in various problems such as wire clamping, wire hanging, wire cutting, and wire stretching, resulting in the inability to rotate to the conductive state or to return to the folded state.

[0078] The movable heating element 131 is detachably arranged on the first air outlet mechanism 340. When the clothes dryer is folded or stored, the movable heating element 131 is first removed from the first air outlet mechanism 340, so that the connecting wires connecting the power supply module and the movable heating element 131 are no longer pulled by the movable heating element 131, avoiding problems such as wire clamping, wire hanging, wire cutting, wire stretching, etc., thereby preventing the clothes dryer from being unable to unfold or fold. When the movable heating element 131 is needed, the clothes dryer can be unfolded first, and then the movable heating element 131 can be installed in the first air outlet mechanism 340, so that the movable air outlet 320 can blow out hot air normally.

[0079] In some embodiments of the present application, in order to realize the switching of the channel structure between the conducting state and the folding state, the channel component 140 is movably arranged on the first air duct member 110, and the channel component 140 can be close to or away from the second air duct member 120 during the state switching process. In this way, when the channel component 140 moves to a position away from the second air duct member 120, the channel component 140 is in a folded state, and the gap between the channel component 140 and the second air duct member 120 can be used for the movable heating member 131 to enter or exit the installation position 130. When the channel component 140 moves to a position close to or located on the second installation member, the channel component 140 can be connected to the second air duct opening 121, so that the second installation opening is connected to the first channel opening through the channel component 140.

[0080] In some embodiments, see Figure 4The channel assembly 140 includes a plurality of channel members 141, each of which can be movably disposed on the first air duct member 110, and each of which can be close to or away from the second air duct member 120 during the movement. When the channel assembly 140 is in a folded state, each of the channel members 141 is located on the first air duct member 110, that is, all of the channel members 141 are stored on the first channel member 141, so as to leave space between the first air duct opening 111 and the second air duct opening 121 for installing the heating element.

[0081] When the channel assembly 140 is in the conducting state, all the channel pieces 141 extend out of the first air duct piece 110 and are connected to each other to form an air guide channel 143, which is respectively connected to the first air duct opening 111 and the second air duct opening 121. That is, after all the channel pieces 141 are extended, the gap between the first air duct opening 111 and the second air duct opening 121 is covered by all the channel pieces 141 to form the air guide channel 143, and the airflow in the second air duct piece 120 can enter the first air duct piece 110 through the air guide channel 143.

[0082] Specifically in some embodiments, all the channel pieces 141 are hinged on the first air duct piece 110 around a hinge axis, and all the channel pieces 141 are arranged around the first air duct opening 111, and each hinge axis intersects with the first direction X, so that when the channel piece 141 rotates around its own hinge axis, the end of the channel piece 141 away from the first air duct piece 110 can approach or move away from the second air duct piece 120, so that all the channel pieces 141 can be stored in the first air duct piece 110, or all the channel pieces 141 extend out of the first air duct piece 110 to be spliced ​​to form an air guide channel 143.

[0083] Specifically, the edge of the first air duct member 110 at the first channel opening is a first polygon, and the edge of the second air duct opening 121 at the second channel opening is a second polygon, and the first polygon and the second polygon have the same number of sides and are parallel to each other. Each channel member 141 is arranged corresponding to one of the sides of the first polygon, and the hinge axis of the channel member 141 is parallel to the opposite side.

[0084] In this way, when all the channel parts 141 are rotated to extend out of the first air duct part 110, all the channel parts 141 will be spliced ​​to form a cylindrical structure, the cross-section of the cylindrical structure is also a first polygon, and an air guide channel 143 will be formed inside the cylindrical structure, thereby connecting the first air duct opening 111 and the second air duct opening 121 through the cylindrical structure.

[0085] It should be noted that, during the rotation of the channel member 141, the end of the channel member 141 away from the first air duct member 110 can be selected according to actual needs to choose whether to contact the second air duct member 120. Specifically, in one embodiment, after all the channel members 141 are spliced ​​to form a cylindrical structure, the end of the cylindrical structure away from the first air duct member 110 can abut against the end surface of the second air duct member 120, thereby connecting the second air duct opening 121 with the air guide channel 143.

[0086] In some other embodiments, the area of ​​the second polygon may be smaller than the area of ​​the first polygon. After all the channel members 141 are spliced ​​together to form a cylindrical structure, one end of the second air duct member 120 having the second air guide member will be located inside the cylindrical structure, thereby connecting the second air duct opening 121 with the air guide channel 143.

[0087] Optionally, the first polygon and the second polygon are both rectangles, and the channel members 141 include four, and the hinge axes of the four channel members 141 are respectively parallel to the four sides of the rectangle.

[0088] Specifically in some embodiments, the heating structure also includes a shell 150, the shell 150 includes an installation space and a disassembly port 151 connected to the installation space, the first air duct member 110 and the second air duct member 120 can be arranged on the shell 150 and located in the installation space, that is, the installation position 130 is located in the installation space, and the movable heating member 131 can enter or leave the installation space through the disassembly port 151, so that the user can disassemble and assemble the movable heating member 131 through the disassembly port 151.

[0089] Furthermore, after the user removes the movable heating element 131, the user can also flip each channel element 141 through the disassembly opening 151, so that the channel assembly 140 is switched to the on state. When the first polygon is a rectangle, the four channel elements 141 are respectively arranged around the first air duct element 110. If the channel element 114 at the bottom of the first air duct element 110 is flipped to the bottom of the first air duct element 110, it will be inconvenient for the user to operate the channel element 141 through the disassembly opening 151 to flip it.

[0090] To this end, a part of the channel piece 141 is used for the hinged end hinged to the first air duct piece 110 and is located on the outer wall of the first air duct piece 110, and another part of the channel piece 141 is used for the hinged end hinged to the air duct piece and is located on the inner wall of the first air duct piece 110, and this part of the channel piece 141 can enter the first air duct opening 111 during the movement relative to the first air duct piece 110, thereby preventing the channel piece 141 from moving to the bottom of the first air duct piece 110 and affecting user operation.

[0091] Specifically, when the first polygon is a rectangle, the hinged ends of the three channel members 141 are respectively arranged on the three outer sides of the first air duct member 110, and the user can directly operate the three channel members 141 through the disassembly opening 151. The last channel member 141 is located at the bottom of the first air duct member 110 away from the disassembly opening 151, and the hinged end of the channel member 141 is located on the inner wall of the first air duct member 110, so that the channel member 141 can be turned over into the first air duct opening 111 during the rotation process relative to the first air duct member 110. When the user operates the channel member 141, he can put his hand into the first air duct opening 111 for operation without putting his hand into the bottom of the first air duct member 110, which improves the convenience of the user to operate the channel assembly 140.

[0092] Specifically in some embodiments, since household appliances such as clothes dryers need to generate airflow through air outlet parts such as blowers when they are working, the blowers will generate vibrations during operation, and the vibrations will cause each channel part 141 to move relative to the first air duct part 110, thereby causing the channel parts 141 to collide with the first air duct part 110, thereby generating noise.

[0093] For this purpose, see Figure 4 , each channel member 141 is provided with a first buckle portion 142, and the first air duct member 110 is provided with a plurality of first matching portions 112. When the channel assembly 140 is in a folded state, each first matching portion 112 is buckled with one of the first buckle portions 142. That is, when each channel member 141 is rotated to be located on the first channel member 141, each channel member 141 can be fixed on the first channel member 141 through the first buckle portion 142 and the second buckle portion 132, so as to avoid collision and noise between the channel member 141 and the first air duct member 110.

[0094] Specifically, when the first polygon is a rectangle and the channel assembly 140 is in a folded state, three first matching portions 112 are located on the outer wall of the first air duct member 110, so that the first buckle portions 142 of the three channel members 141 located on the outer wall of the first air duct member 110 can be mutually buckled with the three first matching portions 112. The last first matching portion 112 is located on the inner wall of the first air duct member 110, so that the first buckle portion 142 of the channel member 141 located inside the first air duct opening 111 can be mutually buckled with the first matching portion 112.

[0095] Further, the first matching portion 112 is a limiting column, and the first buckle portion 142 is a limiting hole. When the first matching portion 112 and the first buckle portion 142 are buckled with each other, the limiting column is inserted into the limiting hole, so that the channel member 141 is prevented from moving relative to the first air duct member 110 by the limiting column. When the limiting column is inserted into the limiting hole, the axis of the limiting column is perpendicular to the hinge axis of the channel member 141 of the limiting column. When the channel member 141 rotates around the hinge axis, the limiting column will be inserted into or leave the limiting hole, so as to realize the buckling or separation of the first buckle portion 142 and the first matching portion 112.

[0096] It is understandable that in some other embodiments, the first matching portion 112 may also be a limiting hole, and the first buckle portion 142 may also be a limiting column.

[0097] In some embodiments, in order to reduce the movement of the channel assembly 140 relative to the first air duct member 110 or the second air duct member 120 when the channel assembly 140 is in the conducting state, the housing 150 and the second air duct member 120 are both provided with a second matching portion 122, see Figure 7 and Figure 8 When the channel assembly 140 is in the folded state, each second matching portion 122 is buckled with one of the first buckling portions 142 , so that the multiple channel members 141 are fixed by the multiple second matching portions 122 , thereby reducing the noise generated by the channel members 141 .

[0098] Specifically, when the second polygon is a rectangle, three second matching portions 122 are respectively provided on the three outer walls of the second air duct member 120, and a second matching portion 122 is also provided on the surface of the housing 150. When the channel assembly 140 is in the conducting state, the first buckle portions 142 of the three channel members 141 can be mutually buckled with the three second matching portions 122 of the second air duct member 120, and the first buckle of the channel member 141 close to the housing 150 is mutually buckled with the second matching portion 122 on the surface of the housing 150.

[0099] Specifically, the first buckle portion 142 is a limiting hole, the second matching portion 122 is a limiting column, and during the rotation of the channel member 141, when the channel member 141 rotates to be located on the first air duct member 110, the limiting column on the first air duct member 110 is inserted into the limiting hole, and when the channel member 141 rotates to be close to the second air duct member 120, the limiting column on the second air duct member 120 is inserted into the limiting hole. In this way, the channel assembly 140 can be kept fixed in both the conducting state and the folded state, thereby reducing the noise generated by the channel assembly 140. It can be understood that in some other embodiments, when the first buckle portion 142 is a limiting column, the first matching portion 112 and the second matching portion 122 are both limiting holes.

[0100] In some embodiments of the present application, refer to Figure 5 When the movable heating element 131 is installed on the installation position 130, the movable heating element 131 also needs to be fixed. For this purpose, a third matching portion is provided on the shell 150, and a second buckle portion 132 is provided on the movable heating element 131. When the movable heating element 131 is set at the installation position 130, the second buckle can be mutually engaged with the third matching portion, so that the movable heating element 131 is fixed on the shell 150 through the buckling of the second buckle and the third matching portion.

[0101] Specifically, the third matching portion is a limiting column, the axis of which is perpendicular to the first direction X and parallel to the axis of the disassembly opening 151, and the second buckle portion 132 is a limiting hole. When the active heating element 131 is placed into the installation position 130 from the disassembly opening 151, the limiting column of the third matching portion will be inserted into the limiting hole of the second buckle portion 132, so that the active heating element 131 is fixed to the housing 150 through the matching of the limiting column and the limiting hole. It can be understood that in some other embodiments, the third matching portion can also be a limiting hole, and the second buckle portion is a limiting column.

[0102] In some embodiments of the present application, the heating structure further includes a cover member 152, which is movably mounted on the housing 150, and during the movement, the cover member 152 opens and closes the disassembly opening 151. When the user does not need to disassemble the heating element, the disassembly opening 151 can be closed by the cover member 152 to prevent dust and other debris from entering the housing 150 and affecting the normal operation of the device.

[0103] Furthermore, the cover member 152 is provided with a third buckle portion 153, and the housing 150 is provided with a fourth matching portion 154. When the cover member 152 closes the disassembly opening 151, the third buckle portion 153 and the fourth matching portion 154 are buckled with each other. Thus, the cover member 152 is fixed to the housing 150 by the buckling of the third buckle and the fourth matching portion 154, so as to prevent the cover member 152 from opening by itself.

[0104] Specifically, the cover member 152 is hinged on the housing 150, and the matching part is a limiting column, the axis of the limiting column is perpendicular to the hinge axis of the cover member 152, and the third buckle part 153 is a limiting hole. When the cover member 152 is rotated to close the disassembly and assembly port 151, the limiting column of the third matching part will be inserted into the limiting hole of the third buckle part 153, so that the cover member 152 is fixed on the housing 150 through the matching of the limiting column and the limiting hole, so that the cover member 152 remains in a closed state. It can be understood that in some other embodiments, the fourth matching part 154 can also be a limiting hole, and the third buckle part is a limiting column.

[0105] It should be noted that, in other embodiments, each channel piece 141 can also be individually and retractably arranged in the first air duct opening 111. When it is necessary to form an air guide channel 143, the user can pull each channel piece 141 out of the first air duct opening 111 to realize splicing of multiple channel pieces 141 to form an air guide channel 143.

[0106] In some other embodiments, the channel assembly 140 may also be a tubular structure, and the tubular channel assembly 140 may be telescopically arranged in the first air duct opening 111, and when the channel assembly 140 extends out of the first channel opening, and one end of the tubular channel assembly 140 is connected to the second air duct opening 121, the channel assembly 140 is in a conducting state. When the duct assembly is completely retracted into the first air duct opening 111, the duct assembly is in a folded state.

[0107] In some other embodiments, the channel assembly 140 may also include a first part and a second part, wherein the first part is movably disposed on the first channel member 141, and the second part is movably disposed on the second channel member 141, the first part can be close to or away from the second channel member 141, and the second part and the first part are spliced ​​with each other to form a connecting pipeline connecting the first air duct opening 111 and the second air duct opening 121.

[0108] The following combination Figure 3 and Figure 8 The working process of the heating structure in the embodiment of the present application is described below:

[0109] When the user needs to install the active heating component 131, the user rotates the four channel components 141 toward the first air duct component 110 respectively until the first snap-fit ​​portions 142 of the four channel components 141 cooperate with the four first matching portions 112 on the first air duct component 110, and then inserts the active heating component 131 between the first air duct opening 111 and the second air duct opening 121, and makes the active heating component 131 connect the first air duct opening 111 and the second air duct opening 121, thereby completing the installation of the active heating component 131.

[0110] When the user needs to disassemble the active heating component 131, the user takes the active heating component 131 out from between the first air duct opening 111 and the second air duct opening 121, and then rotates the four channel components 141 until the first snap-fit ​​portions 142 of the four channel components 141 are snapped with the three second matching portions 122 of the second air duct component 120 and the one second matching portion 122 on the shell 150, so that the four channel components 141 form an air guide channel 143, thereby connecting the first air duct opening 111 and the second air duct opening 121.

[0111] The above heating structure has at least the following advantages:

[0112] When the household appliance is a clothes dryer, if the user selects a configuration without the active heating element 131, the channel assembly 140 is in a conducting state, and the first air duct member 110 and the second air duct member 120 are interconnected, that is, the clothes dryer can work normally without the active heating element 131. When the user is dissatisfied with the current configuration and needs to upgrade to a configuration with an active heating element 131, the user only needs to turn the channel assembly 140 to a folded state and install the active heating element 131 into the installation position 130, thereby realizing the customization of the heating power of the clothes dryer. The user does not need to repurchase or return the entire clothes dryer, but only needs to purchase the active heating element 131 separately to complete the upgrade of the clothes dryer power.

[0113] The movable heating element 131 is detachably arranged on the first air outlet mechanism 340. When the clothes dryer is folded or stored, the movable heating element 131 is first removed from the first air outlet mechanism 340, so that the connecting wires connecting the power supply module and the movable heating element 131 are no longer pulled by the movable heating element 131, avoiding problems such as wire clamping, wire hanging, wire cutting, wire stretching, etc., thereby preventing the clothes dryer from being unable to unfold or fold. When the movable heating element 131 is needed, the clothes dryer can be unfolded first, and then the movable heating element 131 can be installed in the first air outlet mechanism 340, so that the movable air outlet 320 can blow out hot air normally.

[0114] 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.

[0115] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
