[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0027] The dryer uses heat to evaporate the moisture in clothes, thereby achieving the purpose of drying clothes. Especially in humid weather, users can wear dry and comfortable clothes, and can also reduce the space for drying clothes, solving the problem that clothes are difficult to dry naturally in humid weather, thereby effectively improving the quality of life of users.

[0028] Based on this, Figure 1 As shown, an exemplary embodiment of the present invention provides a clothes dryer 10. The clothes dryer 10 can be an independent drying device with only a clothes drying function, or a washer-dryer, a washer-dryer or a clothes processing device with both washing and drying functions.

[0029] The clothes dryer 10 may include a housing (not shown in the figure), a door (not shown in the figure), a clothes dryer 11 and a heating assembly (not shown in the figure). The housing has a containing space and an opening, and the door is rotatably connected to the housing to close the opening or leak out the opening. The clothes dryer 11 is arranged in the containing space. The heating assembly is also arranged in the containing space to transport air with heat into the clothes dryer 11 through the heating assembly, and use the air to dry the moisture in the clothes, so as to achieve the effect of drying the clothes. Of course, the clothes dryer may also include other components, and the above composition should not be understood as a limitation on the structure of the clothes dryer 10.

[0030] Reference Figure 1 As shown, the drying drum 11 has a vacuum chamber 110. The drying drum 11 may include an inner drum 111 and an outer drum 112, which are coaxially arranged and are integrally formed, thereby reducing the manufacturing cost and difficulty of the drying drum 11.

[0031] Among them, the outer wall of the inner drum 111 and the inner wall of the outer drum 112 are spaced at a predetermined distance, thereby forming a vacuum chamber 110, so as to use the vacuum chamber 110 to keep the clothes drying drum 11 warm. Since the transfer of heat requires a medium, a vacuum chamber 110 is formed between the outer wall of the inner drum 111 and the inner wall of the outer drum 112, and when the heat in the clothes drying drum 11 passes through the vacuum chamber 110, the heat transfer process loses the transmission medium and cannot diffuse outward. In other words, in this example, the characteristic of the vacuum thermal conductivity coefficient being zero can completely prevent the loss of internal heat of the clothes drying drum 11 during its operation, thereby keeping the clothes drying drum 11 warm, thereby effectively improving the drying efficiency of clothes.

[0032] At the same time, since the propagation of sound also requires a medium, when the dryer 11 is running, the sound inside it cannot be transmitted to the outside due to the vacuum chamber 110, thereby effectively reducing the working noise of the dryer 11.

[0033] In one example, the thickness of the vacuum chamber 110 can be 0.8 mm to 3.6 mm. The vacuum chamber 110 in this thickness range can not only meet the requirements of thermal insulation and sound insulation, but also keep the wall thickness of the drying drum 11 within a reasonable range, thereby reducing the volume of the drying drum 11 as much as possible.

[0034] When the vacuum chamber 110 is in a vacuum state, the pressure on the outer wall side of the outer drum 112 is greater than the pressure on the inner side of the outer drum 112, and the pressure on the inner wall side of the inner drum 111 is also greater than the pressure on the outer wall side of the outer drum 112. When the clothes dryer 10 is in a working state (the vacuum chamber 110 is in a vacuum state at this time), in order to prevent the atmospheric pressure from affecting the drying drum 11, such as squeezing and deforming the drying drum 11, a plurality of support members 12 are provided in the vacuum chamber 110.

[0035] The plurality of support members 12 and the vacuum chamber 110 of the clothes drying drum 11 are designed as an integrally formed structure, so as to reduce the manufacturing cost and difficulty of the clothes drying drum 11 .

[0036] In some examples, the support member 12 may include but is not limited to a solid support column. Taking a plane parallel to the radial direction of the clothes drying drum 11 as a cross section, the cross-sectional shape of the support column may include but is not limited to a square, a diamond, or a dumbbell shape with a bulge in the middle.

[0037] It should be noted that, in one example, the cross-street shape of the support column can also adopt a double diamond structure in the existing structure (not shown in the figure). Alternatively, the support column can also adopt a hollow structure support ring, etc., wherein the support ring can be provided with stripes of a wavy structure to increase the support structure strength of the support ring.

[0038] In order to improve the uniformity of the support strength of the support member to the vacuum chamber 110, the support member 12 is multi-layered along the height extension direction of the clothes drying drum 11, wherein the support columns in two adjacent layers are staggered. In other words, along the running direction of the clothes drying drum 11, multiple support members 12 on the same cross section and multiple support members 12 adjacent thereto on the same cross section are staggered in structure design.

[0039] Reference Figure 1 As shown, an air extraction hole 13 is provided on the outer drum 112, and one end of the air extraction hole 13 is connected to the vacuum chamber 110. The other end of the air extraction hole 13 is connected to the vacuum pump 15 through a pipe 14. The vacuum pump 15 is used to perform a vacuum process on the vacuum chamber 110, so as to ensure that the vacuum value in the vacuum chamber 110 is within a preset threshold range, so as to effectively prevent the heat loss in the drying drum 11 when the dryer 10 performs a drying operation, thereby improving the drying efficiency of the drying drum 11.

[0040] It should be noted that, in actual applications, those skilled in the art may set the vacuum pump 15 to a screw vacuum pump, or may set the vacuum pump 15 to a Roots vacuum pump, etc. Such adjustments and changes to the specific setting type of the vacuum pump 15 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0041] A vacuum sensor 16 and a solenoid valve 17 are provided on the pipe 14 between the vacuum pump 15 and the air extraction hole 13. The vacuum sensor 16 is provided between the air extraction hole 13 and the solenoid valve 17. It should be noted that the vacuum sensor 16 can also be provided on the wall of the drying drum 11. The vacuum sensor 16 is used to detect the vacuum value in the vacuum chamber 110. Under the control of the control module 18, the solenoid valve 17 is used to open or close the pipe 14.

[0042] At the same time, refer to Figure 1 As shown, the clothes dryer 10 is further provided with a control module 18, which may be a control system provided on the clothes dryer 10, or a control unit provided separately and connected to the control system provided on the clothes dryer 10. The control module 18 may be used to obtain a vacuum value in the vacuum chamber 110, and the control module 18 may also be used to execute the control method of the clothes dryer described in the following embodiments.

[0043] It should be noted that the control module 18 can adopt a control system in the prior art, as long as the control module 18 can control various start or shut down functions of the dryer 10, and the specific structure type and specific control logic of the control module 18 will not be repeated here.

[0044] The control module 18 is electrically connected to the vacuum pump 15 , the vacuum sensor 16 and the solenoid valve 17 , so that the control module 18 can control the actions of the vacuum pump 15 , the vacuum sensor 16 and the solenoid valve 17 .

[0045] In this example, after the clothes dryer 10 is started, the vacuum sensor 16 detects the vacuum value in the vacuum chamber 110, and transmits the detected vacuum value signal to the control module 18. After receiving the vacuum value signal, the control module 18 obtains the vacuum value in the vacuum chamber 110, and compares the vacuum value with the preset threshold range pre-stored in the control module 18 to determine whether the vacuum chamber 110 needs to be evacuated.

[0046] Among them, when the vacuum value is within the preset threshold range, it indicates that the vacuum value at this time meets the operation requirements of the dryer 10. At this time, the control module 18 or the control system of the dryer 10 controls the dryer 10 to normally operate the subsequent drying process to complete the drying of the clothes. It should be noted that the preset threshold range in this example is a range value, which can be an experience value set by the user, or a theoretical value set when the dryer 10 leaves the factory, that is, the specific setting value of the preset threshold range is not specifically limited here.

[0047] When the vacuum value is outside the preset threshold range, that is, the vacuum value is less than the minimum value of the preset threshold range, it is determined that the vacuum value in the vacuum chamber 110 is too small, and there is a risk of heat loss. At this time, the vacuum chamber 110 needs to be evacuated. During the evacuation process, the vacuum pump 15 is first started by the control module 18, and then the solenoid valve 17 is opened to use the vacuum pump 15 to evacuate the vacuum chamber 110.

[0048] During the vacuuming process or after the vacuuming process is completed, the vacuum sensor 16 constantly detects the current vacuum value in the vacuum chamber 110, and when the current vacuum value is within the preset threshold range, the control module 18 determines that the current vacuum value at this time satisfies the use of the clothes drying drum 11. Then, the control module 18 first closes the solenoid valve 17 and then the vacuum pump 15. Finally, the control module 18 or the control system of the clothes dryer 10 controls the clothes dryer 10 to normally operate the subsequent clothes drying process, thereby completing the drying of the clothes.

[0049] like Figure 2 As shown, an exemplary embodiment of the present invention further provides a control method for a clothes dryer, the control method for a clothes dryer comprising the following steps:

[0050] Step S100: obtaining the vacuum value in the vacuum chamber of the clothes drying drum.

[0051] Step S200: selectively controlling the operating state of the dryer according to the relationship between the vacuum value and a preset threshold range.

[0052] In step S100 , the vacuum sensor 16 may be used to detect the vacuum value in the vacuum chamber 110 , and the detected vacuum value signal may be transmitted to the control module 18 , so that the vacuum value in the vacuum chamber 110 may be acquired through the control module 18 .

[0053] In step S200 , the control module 18 receives the vacuum value signal to obtain the vacuum value in the vacuum chamber 110 , and compares the vacuum value with a preset threshold range pre-stored in the control module 18 to determine whether the vacuum chamber 110 needs to be evacuated.

[0054] Among them, when the vacuum value is within the preset threshold range, it indicates that the vacuum value at this time meets the operating requirements of the dryer 10. At this time, the control module 18 or the control system of the dryer 10 controls the dryer 10 to run the subsequent drying processing operations normally to complete the drying of the clothes.

[0055] When the vacuum value is outside the preset threshold range, that is, the vacuum value is less than the minimum value of the preset threshold range, it is determined that the vacuum value in the vacuum chamber 110 is too small, and there is a risk of heat loss. At this time, the vacuum chamber 110 needs to be evacuated. During the vacuum process, the vacuum pump 15 is first started by the control module 18, and then the solenoid valve 17 is opened to use the vacuum pump 15 to evacuate the vacuum chamber 110, thereby effectively ensuring the vacuum value in the vacuum chamber 110. That is to say, by controlling the vacuum value in the vacuum chamber 110 and utilizing the characteristic that the vacuum thermal conductivity is zero, the heat loss inside the dryer drum when the dryer is running is effectively isolated, thereby effectively shortening the drying time.

[0056] like Figure 3 As shown, in some embodiments, in the process of obtaining the vacuum value in the vacuum chamber 110 in the drying drum 11, the dryer 10 can be started based on the user end of the dryer 10. Then, the vacuum data in the vacuum chamber 110 is detected by the vacuum sensor 16, and the vacuum data in the vacuum chamber 110 is transmitted to the control module 18 through the data harness. Finally, the control module 18 receives the vacuum data, thereby obtaining the vacuum value in the vacuum chamber 110.

[0057] like Figure 3 As shown, in some embodiments, the process of comparing the vacuum value with the preset threshold range may include the following methods:

[0058] When the vacuum sensor 16 detects that the vacuum value in the vacuum chamber 110 is within the preset threshold range, it indicates that the vacuum value at this time meets the operating requirements of the dryer 10. At this time, the control module 18 or the control system of the dryer 10 controls the dryer 10 to normally run the subsequent drying processing operations to complete the drying of the clothes.

[0059] When the vacuum sensor 16 detects that the vacuum value in the vacuum chamber 110 is outside the preset threshold range, that is, when the vacuum value is less than the minimum value of the preset threshold range, the control module 18 determines that the vacuum value in the vacuum chamber 110 is small at this time. If the clothes drying care program of the clothes dryer 10 is started at this time, there is a risk of heat loss in the wall of the clothes drying drum 11. Therefore, the vacuum chamber 110 needs to be evacuated to ensure that the vacuum chamber 110 has a vacuum value that meets the conditions.

[0060] During the vacuuming process, the vacuum pump 15 is first started through the control module 18, and then the solenoid valve 17 is opened to use the vacuum pump 15 to evacuate the vacuum chamber 110, thereby effectively ensuring the vacuum value in the vacuum chamber 110. That is to say, by controlling the vacuum value in the vacuum chamber 110 and utilizing the characteristic that the vacuum thermal conductivity is zero, the heat loss inside the dryer drum when the dryer is running is effectively isolated, thereby effectively shortening the drying time.

[0061] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
