Description

Technical Field

[0001] This disclosure relates to the field of clothing drying technology, and in particular to a drying tunnel, drying assembly, and clothing processing equipment for clothing processing. Background Technology

[0002] With the development of technology, garment processing equipment typically includes a drying section for drying clothes. In related technologies, heating elements are usually installed within the drying tunnel to heat the drying gases, thereby achieving the drying function. However, this setup has significant drawbacks. On the one hand, the presence of the heating elements interferes with the airflow within the drying tunnel, leading to uneven airflow distribution and affecting drying efficiency and the drying effect on the clothes. On the other hand, the lint generated by the clothes during the drying process easily accumulates around the heating elements, causing blockages. This not only affects the normal operation of the heating elements but also increases the equipment's energy consumption and the risk of malfunction. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a drying tunnel, a drying assembly, and a garment processing device.

[0006] Optionally, the receiving cavity surrounds the outer periphery of the internal cavity.

[0007] Optionally, the number of the receiving cavities is multiple and they are arranged along the annular cross-section of the drying tunnel body.

[0008] Optionally, a weight-reducing hole is provided on the sidewall at a position between two adjacent receiving cavities.

[0009] Optionally, the receiving cavity is constructed as a single-sided opening structure that is closed at one end.

[0010] Optionally, in the longitudinal direction of the drying tunnel body, the extension length of the receiving cavity (3) is at least 3 / 4 of the length of the drying tunnel body.

[0011] Optionally, the receiving cavity is located on the air inlet side of the drying tunnel body.

[0012] Optionally, the receiving cavity is constructed as a stepped structure having an opening portion and an inner portion, the inner portion for receiving the main body portion of the heating element, and the opening portion for fitting the sealing portion of the heating element in a shape-matched manner.

[0014] Optionally, it may also include a fan disposed at one end of the drying tunnel body.

[0015] According to a third aspect of the present disclosure, a garment processing apparatus is provided, including the drying assembly described above.

[0016] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: by arranging the heating element in the mounting part so that the heating element and the internal cavity of the drying tunnel body are isolated from each other through the side wall of the drying tunnel body, compared with placing the heating element directly in the internal cavity, it helps to increase the airflow of the internal cavity and reduce the risk of lint clogging around the heating element, thereby improving drying efficiency.

[0017] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] Reference Figures 1-3 This disclosure exemplarily illustrates a drying tunnel for a garment processing device, including a drying tunnel body 1. The drying tunnel body 1 has an internal cavity 101 for gas flow. The internal cavity 101 refers to a channel extending through the length of the drying tunnel body 1, located inside the side wall of the drying tunnel body 1. This channel is used to allow gas to flow from one end to the other to blow-dry the garments inside the drum. Its cross-sectional outline can be rectangular, circular, etc., and this disclosure does not limit it. The drying tunnel body 1 is provided with a mounting part for arranging a heating element 2. The mounting part is isolated from the internal cavity 101 by the side wall 102 of the drying tunnel body 1, that is, the mounting part is located outside the internal cavity 101 and does not occupy the accommodating space of the internal cavity 101.

[0026] This disclosure does not limit the mounting portion. For example, it can be a receiving cavity 3 formed on the sidewall 102 of the drying tunnel body 1, as mentioned below. In this case, a portion of the sidewall 102 is used to form the receiving cavity 3, and another portion is used to isolate the receiving cavity 3 from the internal cavity 101. Alternatively, in some other embodiments, the mounting portion may also include a groove formed on the outer surface of the sidewall 102, in which the heating element 2 can be arranged. In this case, the mounting portion may also include a cover covering the groove to reduce heat loss from the heating element 2. Alternatively, the outer surface of the sidewall 102 can also be used directly as the mounting portion, i.e., the heating element 2 is mounted on the outer surface of the sidewall 102. Similarly, in this case, the mounting portion may also include a cover covering the heating element 2. This disclosure does not limit the specific structure and location of the mounting portion, as long as it is isolated from the internal cavity 101 by the sidewall 102 so that the heating element 2 does not occupy the space of the internal cavity 101.

[0027] In the embodiments of this disclosure, the heating element 2 can be an electric heating tube heater, a heat pump heater, a PTC heater, etc., as long as it can be used to heat the flowing gas in the internal cavity 101.

[0028] It should be noted that the clothing processing equipment disclosed herein may refer to washer-dryer combos, dryers, etc.

[0029] By using the above technical solution, by arranging the heating element 2 in the mounting part so that the heating element 2 and the internal cavity 101 of the drying tunnel body 1 are isolated from each other by the side wall 102 of the drying tunnel body 1, compared with directly placing the heating element 2 in the internal cavity 101, it helps to increase the airflow of the internal cavity 101 and reduce the risk of lint clogging around the heating element 2, thereby improving the drying efficiency.

[0030] Reference Figures 1-3 In the embodiments of this disclosure, the end face 1021 of the sidewall 102 may have an inwardly recessed receiving cavity 3, which serves as a mounting portion. Here, the end face 1021 refers to one end face of the sidewall 102 in the length direction, which is inwardly recessed to form the receiving cavity 3. That is, the receiving cavity 3 is formed within the sidewall 102, and is separated from the internal cavity 101 by the portion of the sidewall 102 located inside the receiving cavity 3. This design avoids the heating element 2 from occupying the space of the internal cavity 101, and also avoids the heating element 2 from occupying the outer space of the drying tunnel body 1, which helps to reduce the volume of the drying tunnel itself. In addition, by placing it inside the sidewall 102, compared to placing it on the outer surface of the sidewall 102, the heating element 2 can be closer to the internal cavity 101, improving heat transfer efficiency. Furthermore, there is no need to add a cover or other structure to the outside of the heating element 2 to reduce heat loss; the portion of the sidewall 102 located outside the receiving cavity 3 can achieve this function, effectively reducing the complexity of the drying tunnel. Furthermore, compared to directly placing the heating element 2 on the outer surface of the side wall 102, this design avoids interference between the heating element 2 and external components, thus improving safety. In the embodiments of this disclosure, the receiving cavity 3 can be integrally formed with the drying tunnel body 1, or it can be formed later.

[0031] In embodiments of this disclosure, the receiving cavity 3 may surround the outer periphery of the internal cavity 101. Here, "surround" means that in a cross-section perpendicular to the length direction of the drying tunnel body 1, the receiving cavity 3 is located on the outer periphery of the internal cavity 101 and matches the outer contour of the internal cavity 101, so that there is a receiving cavity 3 close to the internal cavity 101 at various positions in the circumferential direction. This allows the heating element 2 to be installed in the receiving cavity 3 to uniformly heat various positions of the internal cavity 101, thereby improving heating efficiency and heating uniformity.

[0032] In order for the receiving cavity 3 to surround the outer periphery of the inner cavity 101, refer to Figure 3 In some embodiments, the number of receiving cavities 3 can be multiple and arranged along the annular cross-section of the drying tunnel body 1. This design, with multiple receiving cavities 3 arranged sequentially, reduces the molding difficulty of a single receiving cavity 3, and similarly reduces the manufacturing difficulty of a single heating element 2 (manufacturing a single large annular heating element 2 and an annular receiving cavity 3 is more difficult). For example, in... Figure 2 and Figure 3 In the illustrated embodiment, the cross-section of the outer contour of the internal cavity 101 can be rectangular, allowing flat cuboid receiving cavities 3 to be formed on its four sides. Similarly, flat cuboid heating elements 2 can be arranged in each receiving cavity 3, simplifying the molding process of this regular cuboid structure. Furthermore, when there are multiple heating elements 2, each element can be individually controlled according to actual needs, improving operability. Of course, besides the above embodiment, the receiving cavity 3 can also be designed as a single ring, its overall structure being annular around the internal cavity 101, with the heating element 2 also constructed as an annular shape matching the shape of the receiving cavity 3.

[0033] Reference Figure 3 In the embodiments of this disclosure, a weight-reducing hole 103 may be provided on the sidewall 102 at a position between two adjacent receiving cavities 3. Since it is necessary to form the receiving cavity 3 within the sidewall 102, it is necessary to ensure that the sidewall 102 has a certain thickness. In this case, by providing the weight-reducing hole 103, the weight of the drying tunnel body 1 can be effectively reduced, which is beneficial for weight reduction.

[0034] In embodiments of this disclosure, in order to prevent heat loss from the receiving cavity 3 and thus energy waste, the receiving cavity 3 can be constructed as a single-sided open structure with one end closed.

[0035] In the embodiments of this disclosure, the extension length of the receiving cavity 3 in the longitudinal direction of the drying tunnel body 1 is at least 3 / 4 of the length of the drying tunnel body 1, for example, specifically 3 / 4, 5 / 6, etc. This design ensures that the heating elements 2 are distributed to a greater extent in the longitudinal direction of the drying tunnel body 1, thereby allowing the gas to be heated for a longer period of time as it flows from one end of the internal cavity 101 to the other end, thus ensuring the drying effect.

[0036] Reference Figure 1 and Figure 2 In the embodiments of this disclosure, the receiving cavity 3 can be opened on the air inlet side of the drying tunnel body 1, that is, the side of the drying tunnel body 1 used for installing the fan 4. With this design, the gas can be heated as soon as it enters the drying tunnel body 1, effectively increasing the gas heating time and thus ensuring the drying effect.

[0037] Reference Figure 1 and Figure 2In embodiments of this disclosure, the receiving cavity 3 can be configured as a stepped structure with an opening and an inner portion. The inner portion is used to receive the main body portion 201 of the heating element 2, and the opening portion is used to fit the sealing portion 202 of the heating element 2 in a shape-matched manner. With the aforementioned structure, the sealing portion 202 is fitted into the opening portion in a shape-matched manner, thereby forming a sealed space within the receiving cavity 3, effectively reducing heat loss from the main body portion 201 of the heating element 2, and maximizing its heating of the gas within the internal cavity 101.

[0038] According to a second aspect of this disclosure, a drying assembly is provided, including a heating element 2 and the drying tunnel of the aforementioned garment processing equipment. The heating element 2 is disposed in the mounting portion. Since the drying assembly has all the beneficial effects of the drying tunnel of the aforementioned garment processing equipment, it will not be described in detail here.

[0039] Reference Figures 1-3 In embodiments of this disclosure, the drying assembly may further include a fan 4 disposed at one end of the drying tunnel body 1. By providing the fan 4, flowing gas can be generated within the internal cavity 101. After being heated by the heating element 2, the flowing gas is blown into the drum containing the clothes to be dried, thereby drying the clothes.

[0040] According to a third aspect of this disclosure, a garment processing apparatus is provided, including the aforementioned drying assembly. Since the garment processing apparatus has all the beneficial effects of the aforementioned drying assembly, further details are omitted here.

[0041] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0042] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0043] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0044] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0045] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature.

[0046] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0047] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0048] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0049] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
