[0005] In some related technologies, the temperature sensing part of the temperature controller extends into the drying duct and senses the temperature by contacting the air inside the drying duct. In this case, on the one hand, the temperature sensing part of the temperature controller is easily damaged in a high-temperature and humid environment for a long time, and is affected by the flowing air in the drying duct, thereby affecting the temperature detection accuracy.

[0039] Please refer to Figures 1 to 4. This application provides a drying tunnel device 1.

[0040] It is understood that the application field of the drying tunnel device 1 is not limited. This application embodiment takes the application of the drying tunnel device 1 in clothing processing equipment as an example for illustration.

[0041] Specifically, this application also provides a garment processing device, including a drum assembly and a drying tunnel device 1 according to any embodiment of this application.

[0042] Clothing processing equipment can be a drum washing machine with drying function, or a washer-dryer combo, etc., without any restrictions.

[0043] The tube assembly has a clothing handling chamber, an air inlet, and an air outlet.

[0044] The clothes are washed and cared for inside the garment processing chamber. One side of the garment processing chamber is open, forming a garment loading port through which users can put or take clothes.

[0045] Exemplarily, the drum assembly includes an inner drum and an outer drum, with the outer drum fitted over the inner drum. The outer drum holds water for washing clothes, while the inner drum holds the clothes. The space within the inner drum defines a clothes handling chamber. Exemplarily, the inner drum and outer drum are coaxially arranged. Perforations are formed in the side wall of the inner drum, allowing water from the outer drum to enter the inner drum through these perforations to wash the clothes in the clothes handling chamber. Simultaneously, during the drying process, the hot, dry airflow, after heat and moisture exchange with the clothes in the clothes handling chamber, can also enter the outer drum through the perforations in the inner drum. In this embodiment, the inner drum can also be referred to as a perforated inner drum.

[0046] The laundry treatment cavity is communicated with the air inlet and the air outlet. When the laundry in the laundry treatment cavity is dried, dry hot air flows into the laundry treatment cavity through the air inlet to exchange heat and moisture with the laundry in the laundry treatment cavity, and the air flows out of the laundry treatment cavity through the air outlet.

[0047] Referring to FIGS. 1-4, the drying duct device 1 includes a housing 10, a temperature controller 12, and an adapter 11. Specifically, the drying duct device 1 is arranged outside the outer tub.

[0048] The housing 10 has an air duct for communicating with the laundry treatment cavity of the laundry treatment apparatus. The housing 10 has an air inlet 10b and an air outlet 10c, and the air duct communicates the air inlet 10b and the air outlet 10c. The air inlet 10b is communicated with the air outlet, and the air outlet 10c is communicated with the air inlet.

[0049] Specifically, the air duct is used for air flow. After the wet hot air flows out of the laundry treatment cavity, it is condensed to form low-temperature dry air. The low-temperature dry air enters the air duct through the air inlet 10b, is heated in the air duct to form dry hot air, and the dry hot air exits the air duct through the air outlet 10c and enters the laundry treatment cavity through the air inlet.

[0050] It can be understood that the way of condensing the wet hot air is not limited.

[0051] For example, in some embodiments, the laundry treatment apparatus is provided with a condensation pipeline on the back side of the back plate, and the condensation pipeline is communicated with the air duct. The wet hot air is dehumidified in the condensation pipeline to form low-temperature dry air.

[0052] Hereinafter, the drying process and principle of the laundry treatment apparatus in the embodiments of the present application are briefly described.

[0053] When the laundry treatment apparatus is drying the laundry, the dry hot air enters the laundry treatment cavity from the air outlet 10c through the air inlet. In the laundry treatment cavity, the dry hot air flows through the surface of the wet laundry, exchanges heat and moisture with the wet laundry, absorbs the moisture in the laundry, becomes wet hot air, and exits the laundry treatment cavity. After being dehumidified, the low-temperature dry air is formed, and the low-temperature dry air enters the air duct through the air inlet 10b. The low-temperature dry air is heated in the air duct by the heating element to form dry hot air, and the dry hot air exits the air duct through the air outlet 10c and enters the laundry treatment cavity through the air inlet. In this way, the cycle is run to achieve continuous and efficient drying of the laundry.

[0054] It should be noted that the low-temperature dry air is relative to the wet hot air, and the temperature of the low-temperature dry air is lower than that of the wet hot air. The low temperature in the embodiments of the present application can be room temperature.

[0055] It can be understood that a filter can also be arranged in the air duct to filter the airflow flowing through the air duct, reduce the probability of lint generated by the clothes adhering to the heating element in the air duct, reduce the risk of lint dry burning, and improve the drying efficiency.

[0056] Referring to FIGS. 1 and 2, the temperature controller 12 is arranged outside the shell 10, and the temperature controller 12 has a temperature sensing part 12a.

[0057] It should be noted that the temperature controller 12 is arranged outside the shell 10, which means that any part of the temperature controller 12 is located outside the shell 10, and the temperature controller 12 does not directly contact the airflow in the air duct.

[0058] Here, the temperature sensing part 12a refers to the part of the temperature controller 12 used to sense the temperature, and the temperature sensing part 12a realizes the sensing of the temperature by the temperature controller 12.

[0059] The outer part of the side wall of the air duct is provided with a first mounting surface 10a.

[0060] It should be noted that the side wall of the air duct refers to the side wall directly forming the air duct, the inner part of the side wall of the air duct directly contacts the airflow, and the outer part of the side wall of the air duct is the side of the side wall of the air duct away from the air duct. That is, the first mounting surface 10a can directly reflect the temperature of the airflow in the air duct.

[0061] Referring to FIGS. 1 and 4, the adapter 11 and the first mounting surface 10a define a containing cavity 11a, the containing cavity 11a is not in communication with the air duct, and the temperature sensing part 12a is located in the containing cavity.

[0062] It can be understood that the containing cavity 11a is not in communication with the air duct, which means that the containing cavity 11a and the air duct are independent of each other and do not affect each other. The temperature sensing part 12a arranged in the containing cavity 11a will not contact the airflow in the air duct through the containing cavity 11a.

[0063] Specifically, the containing cavity 11a provides a containing space for the temperature sensing part 12a of the temperature controller 12, which protects the temperature sensing part 12a. In addition, the containing cavity 11a can also provide a relatively closed sensing space for the temperature sensing part 12a, reduce heat loss, and improve the accuracy of the temperature sensing part 12a in sensing the temperature in the air duct transmitted by the first mounting surface 10a.

[0064] It can be understood that the temperature sensing part 12a is arranged in the space defined by the adapter 11 and the first mounting surface 10a, and the temperature sensing part 12a can contact the first mounting surface 10a or have a certain distance from the first mounting surface 10a.

[0065] The oven device 1 provided by the embodiment of the present application is provided with the adapter 11, so that the temperature sensing part 12a of the temperature controller 12 can directly sense the temperature outside the side wall of the air duct without directly contacting the airflow in the air duct, reducing the probability that the temperature controller 12 is damaged and the detection is inaccurate due to the direct contact with the airflow and the influence of the flowing airflow, and reducing the probability that the foam or liquid overflow enters the air duct to cause the short circuit of the temperature controller 12, and increasing the working safety of the temperature controller 12. In addition, the temperature controller 12 can directly sense the temperature of the air duct transmitted by the first mounting surface, the detection accuracy is high, and the auxiliary heat conduction structure does not need to be contacted, and the structure of the oven device 1 is more simple and reliable. In addition, the temperature sensing part 12a of the temperature controller 12 is arranged in the area defined by the adapter 11 and the first mounting surface 10a, which can also reduce the manufacturing requirements of the shell 10, and the connection position of the shell 10 and the temperature controller 12 does not need to be arranged, the connection gap is reduced, and the air duct sealing performance is increased.

[0066] In some embodiments, the first mounting surface 10a is a complete surface.

[0067] It should be noted that the complete surface means that the first mounting surface 10a is not disconnected or separated, the first mounting surface 10a is a complete surface, and the first mounting surface 10a is free of notches, gaps or hole positions.

[0068] The adapter 11 is connected with the first mounting surface 10a and defines the accommodating cavity 11a.

[0069] It can be understood that the connection of the adapter 11 and the first mounting surface 10a does not affect the integrity of the first mounting surface 10a, that is, the connection with the adapter 11 does not need to be realized by punching the first mounting surface 10a and the like.

[0070] In the related art, the side wall of the air duct is provided with a hole, the temperature sensing part of the temperature controller passes through the side wall of the air duct, and the temperature is sensed by contacting the air in the air duct. The temperature controller is easy to be damaged and is prone to overflow short circuit risk, and the shell needs to be punched, which affects the sealing performance of the air duct.

[0071] In the embodiment, the first mounting surface 10a is a complete surface, that is, the side wall of the air duct does not need to be punched, which reduces the manufacturing difficulty of the shell 10, increases the sealing performance of the air duct, and increases the overall working reliability of the oven device 1.

[0072] In some embodiments, the temperature controller 12 is connected with the adapter 11, and the temperature sensing part 12a of the temperature controller 12 is in contact with the first mounting surface 10a.

[0073] The temperature controller 12 is connected with the adapter 11, that is, the temperature controller 12 is not directly connected with the first mounting surface 10a, and the temperature sensing part 12a of the temperature controller 12 is in contact with the first mounting surface 10a. It is referred to that, after the temperature controller 12, the adapter 11 and the shell 10 are installed, the temperature sensing part 12a of the temperature controller 12 is in physical contact with the first mounting surface 10a. The temperature controller 12 does not need to be in contact with the airflow in the air duct, and the temperature of the airflow in the air duct is sensed by the temperature controller 12 through the contact of the temperature sensing part 12a and the first mounting surface 10a, so as to monitor the temperature of the airflow in the air duct in real time, so as to adjust the heating amount as needed, reduce the probability of overheating, and protect the clothes.

[0074] It can be understood that, in some embodiments, after the temperature controller 12 is connected with the adapter 11, the temperature controller 12 can rely on the cooperation of its own structure and the adapter 11 to close the containing cavity 11a, so that the temperature sensing part 12a of the temperature controller 12 is located in a relatively closed space, thereby reducing heat loss. At the same time, the temperature sensing part 12a is in contact with the first mounting surface 10a, which further increases the accuracy of temperature sensing.

[0075] The connection mode of the adapter 11 and the first mounting surface 10a is not limited, which can be welding, bonding and the like without affecting the integrity of the first mounting surface 10a.

[0076] Exemplarily, in some embodiments, the adapter 11 is welded with the first mounting surface 10a.

[0077] In this embodiment, the adapter 11 and the first mounting surface 10a are connected together by welding, which can stably connect the adapter 11 and the first mounting surface 10a, so that the adapter 11 and the shell 10 are not easily separated, thereby increasing the installation stability of the temperature controller 12, and at the same time, the integrity of the first mounting surface 10a is not affected.

[0078] It can be understood that the first mounting surface 10a can be substantially planar, that is, the first mounting surface 10a has no obvious groove, so that the temperature sensing part 12a of the temperature controller 12 is in close contact with the first mounting surface 10a, so as to accurately measure the temperature of the airflow in the air duct. Of course, the first mounting surface 10a can also be curved, which is not limited here.

[0079] The specific structure of the adapter 11 is not limited.

[0080] In some embodiments, referring to FIGS. 1 and 2, the adapter 11 includes a plate body 111 and a mounting structure 112 connected with each other, the plate body 111 is in contact with and connected with the first mounting surface 10a, the mounting structure 112 protrudes from the side of the plate body 111 away from the first mounting surface 10a, and the temperature controller 12 is connected with the mounting structure 112.

[0081] It can be understood that the plate body 111 refers to a structure substantially in the form of a flat plate. The plate body 111 serves as a bridge connecting the adapter 11 and the first mounting surface 10a, and achieves the installation of the temperature controller 12.

[0082] The plate body 111 is in contact with and connected to the first mounting surface 10a, which means that the plate body 111 is in a state of being attached to the first mounting surface 10a after being connected to the first mounting surface 10a. For example, the plate body 111 and the first mounting surface 10a are connected together by welding.

[0083] The flat plate structure of the plate body 111 can facilitate full attachment to the first mounting surface 10a in the embodiment in which the first mounting surface 10a is flat.

[0084] The mounting structure 112 protrudes from the side of the plate body 111 away from the first mounting surface 10a, i.e., a space is formed between the mounting structure 112 and the first mounting surface 10a for the temperature sensing part 12a of the temperature controller 12.

[0085] In this embodiment, the structure of the adapter 11 is connected to the first mounting surface 10a through the plate body 111, the mounting structure 112 is connected to the temperature controller 12, and space is provided for the temperature sensing part 12a of the temperature controller 12 to contact the first mounting surface 10a, thereby increasing the installation reliability of the temperature controller 12 and the overall structural stability of the baking tunnel device 1.

[0086] The specific structure of the mounting structure 112 is not limited.

[0087] In some embodiments, referring to FIGS. 2 and 4, the mounting structure 112 includes a side wall part 1121 and an end plate part 1122. The side wall part 1121 connects the end plate part 1122 and the plate body 111. The side wall part 1121, the end plate part 1122, and the first mounting surface 10a together define a receiving cavity 11a. The end plate part 1122 is provided with a through hole 1122a, and the temperature controller 12 is arranged in the through hole 1122a and connected to the end plate part 1122.

[0088] Specifically, the side wall part 1121 extends from the connection with the plate body 111 to the side away from the first mounting surface 10a. The side wall part 1121 can be substantially perpendicular to the plate body 111. The side wall part 1121 can support the end plate part 1122 and achieve the connection between the end plate part 1122 and the plate body 111.

[0089] The end plate part 1122 extends from the end of the side wall part 1121 away from the plate body 111. The end plate part 1122 can be substantially in the form of a flat plate. Specifically, the end plate part 1122 can be substantially parallel to the plate body 111.

[0090] The flat structure of the end plate portion 1122 can facilitate connection with the temperature controller 12 and increase connection stability.

[0091] In this embodiment, the side wall portion 1121 and the end plate portion 1122 can provide stable support for the connection of the temperature controller 12 with the end plate portion 1122. The side wall portion 1121, the end plate portion 1122, and the first mounting surface 10a together define a receiving cavity 11a that accommodates the temperature sensing portion 12a of the temperature controller 12. The through hole 1122a on the end plate portion 1122 can position the temperature controller 12 and facilitate the temperature sensing portion 12a of the temperature controller 12 to pass through the through hole 1122a and enter the receiving cavity 11a to contact the first mounting surface 10a, thereby increasing the installation accuracy of the temperature controller 12.

[0092] The specific structure of the temperature controller 12 is not limited.

[0093] In some embodiments, referring to FIGS. 1 and 2, the temperature controller 12 includes a main body portion 122 and a disc portion 121 connected to the circumferential outer side of the main body portion 122. Part of the structure of the main body portion 122 passes through the through hole 1122a, and the disc portion 121 is located on the side of the end plate portion 1122 away from the side wall portion 1121 and is connected to the end plate portion 1122.

[0094] It can be understood that the disc portion 121 is a generally circular or elliptical portion connected to the circumferential outer side of the main body portion 122.

[0095] The disc portion 121 contacts and is connected to the end plate portion 1122. The disc portion 121 and the end plate portion 1122 can have sufficient contact area, thereby facilitating increased connection stability of the end plate portion 1122 and the disc portion 121, and thereby facilitating stable contact of the temperature sensing portion 12a with the first mounting surface 10a. Similarly, the cooperation of the disc portion 121 and the main body portion 122 can also seal the connection of the temperature controller 12 with the end plate portion 1122, so that the temperature sensing portion 12a is in a relatively sealed space, thereby facilitating the temperature sensing portion 12a to sense the temperature of the first mounting surface 10a.

[0096] Part of the structure of the main body portion 122 (including the temperature sensing portion 12a) passes through the through hole 1122a to facilitate contact with the first mounting surface 10a and thereby sense changes in the temperature in the air duct. Another part of the structure protrudes from the mounting structure 112 on the side away from the first mounting surface 10a to facilitate installation and maintenance for adjustment.

[0097] In some embodiments, the air duct device 1 includes one or more connecting members that pass through the disc portion 121 and the end plate portion 1122 to connect the disc portion 121 and the end plate portion 1122.

[0098] In the embodiment, the connecting piece is used to connect the disc part 121 and the end plate part 1122, so as to connect the temperature controller 12 and the adapter 11, which can increase the connection stability of the temperature controller 12 and the adapter 11, and reduce the probability of movement and shaking of the temperature controller 12.

[0099] The number of connecting pieces can be two, so as to increase the connection stability of the temperature controller 12 and the end plate part 1122.

[0100] It can be understood that the specific structure of the connecting piece is not limited, and the connecting piece can be a screw, or a screw and a nut.

[0101] In some embodiments, referring to FIGS. 1 and 2, the side wall of the shell 10 comprises one or more positioning structures 101 protruding from the first mounting surface 10a, and the plate body 111 is provided with a positioning hole 111a, and the positioning structure 101 penetrates the positioning hole 111a.

[0102] In the embodiment, the positioning structure 101 cooperates with the positioning hole 111a, which facilitates accurate positioning between the plate body 111 and the side wall of the shell 10, reduces installation deviation, and the positioning structure 101 penetrating the positioning hole 111a can also limit the movement of the plate body 111, thereby increasing the connection stability. At the same time, manual alignment of the plate body 111 and the side wall of the shell 10 is not required, and assembly is fast and accurate.

[0103] In some embodiments, referring to FIG. 4, at least a portion of the shell 10 comprises a first half shell 1031 and a second half shell 1032, the first half shell 1031 comprises a first shell body 10311 and a first flange 10312 connected to each other, the first flange 10312 is arranged on at least two opposite sides of the first shell body 10311 along a first direction, the second half shell 1032 comprises a second shell body 10321 and a second flange 10322 connected to each other, the second flange 10322 is arranged on at least two opposite sides of the second shell body 10321 along the first direction, the first shell body 10311 and the second shell body 10321 are butted along a second direction and jointly define at least a portion of an air duct, the first flange 10312 and the second flange 10322 are arranged in layers and connected, and the temperature controller 12 is connected to the outside of the first shell body 10311 or the second shell body 10321 through the adapter 11, wherein the first direction and the second direction intersect.

[0104] It can be understood that the first shell body 10311 and the second shell body 10321 jointly define at least part of the air duct, and the side wall of the air duct includes the side wall of the first shell body 10311 and the side wall of the second shell body 10321. The first flange 10312 and the second flange 10322 do not constitute the air duct, and are used to connect the first half shell 1031 and the second half shell 1032. The first flange 10312 and the second flange 10322 do not pass through the airflow.

[0105] It should be noted that the laminated arrangement of the first flange 10312 and the second flange 10322 means that the first flange 10312 and the second flange 10322 are stacked along the second direction, and the opposite sides of the first flange 10312 and the second flange 10322 are attached.

[0106] Specifically, the first flange 10312 and the second flange 10322 can be connected by threaded connection or the like.
