Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to mite-removing vacuum cleaners. Background Technology

[0002] A mite-removing vacuum cleaner is a common household appliance, primarily used to clean dust and mites adhering to fabrics such as beds, sofas, and carpets. When working, the vacuum cleaner uses a motor to provide suction, drawing in dust and mites from the surface and interior of the fabric and collecting them in a dust cup. The airflow is then filtered through the dust cup and exits through the motor's outlet. Currently, some mite-removing vacuum cleaners have a heater on the motor's outlet side to heat the airflow. This heated air, when blown onto the fabric surface, helps to dry the fabric more effectively, thus inhibiting mite growth. However, in related technologies, the heating effect of the airflow in these mite-removing vacuum cleaners is not ideal. Utility Model Content

[0018] In one embodiment, the motor assembly includes a motor housing and a motor mounted within the motor housing, the motor housing having a first outlet and a plurality of second outlets.

[0019] In one embodiment, the motor housing assembly includes an inner housing portion and an outer housing portion connected together, the outer housing portion surrounding the outer side of the inner housing portion to form an airflow channel between them, the inner housing portion having a mounting cavity on its inner side, and the motor being mounted in the mounting cavity;

[0020] The second outlet is located in the outer shell and communicates with the airflow channel. The inner shell has a notch that communicates with the airflow channel and the mounting cavity.

Therefore, the airflow exiting from the first outlet of the motor assembly flows into the heating chamber through the air inlet, is heated by the heater inside, and blown onto the fabric surface from the outlet. Because the heater is located on the airflow path between the air inlet and outlet, when the cross-sectional area of ​​the air inlet is smaller than that of the outlet, the airflow can first gather and then disperse within the heating chamber, fully flowing through the heater and thus being fully heated. This optimizes the heating effect on the blown airflow, making it easier to keep the fabric surface dry and more effectively inhibiting the growth of mites. Attached Figure Description

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] See Figures 1 to 4 An embodiment of this application provides a mite-removing vacuum cleaner including a motor assembly 100 and a heating assembly 200. The motor assembly 100 has a first outlet 11521. See also... Figures 5 to 7 ,as well as Figure 11 The heating assembly 200 includes an outer cover 210 and a heater 220. The outer cover 210 has a heating cavity 211, and an air inlet 212 and an air outlet 213 connected to the heating cavity 211. The air inlet 212 is connected to a first outlet 11521, and the air outlet 213 is used to connect to the external environment. The heater 220 is installed inside the heating cavity 211 and is located on the airflow path between the air inlet 212 and the air outlet 213. The air inlet 212 is located at one end of the outer cover 210 along a first direction, and the air outlet 213 is located at the other end of the outer cover 210 along the first direction. The first direction is one of the length direction, width direction, or thickness direction of the outer cover 210.

[0049] In the aforementioned mite-removing vacuum cleaner, the heating assembly 200 has an air inlet 212 connected to a first outlet 11521, an air outlet 213 for connecting to the external environment, and a heater 220 installed inside the heating chamber 211, located on the airflow path between the air inlet 212 and the air outlet 213. Therefore, the airflow from the first outlet 11521 of the motor assembly 100 will flow from the air inlet 212 into the heating chamber 211, be heated by the heater 220 installed inside the heating chamber 211 to form hot air, and then blown onto the fabric surface from the air outlet 213. Since the heater 220 is located on the airflow path between the air inlet 212 and the air outlet 213, the design of the air inlet 212 and the air outlet 213 being positioned at opposite ends of the outer cover 210 along the first direction allows the airflow to fully pass through the heater 220, thus ensuring sufficient heating and optimizing the heating effect on the blown airflow. This makes it easier to keep the fabric surface dry and more effectively inhibits the growth of mites.

[0050] Specifically, the heating element 200 is disposed radially outward of the motor assembly 100. In the embodiment shown in the figures, the first direction is the radial direction of the motor assembly 100, which is also the thickness direction of the heating element 200. In other embodiments, the first direction may also be the length direction or the width direction of the heating element 200.

[0051] See Figures 1 to 3 ,as well as Figure 11 The mite-removing vacuum cleaner includes a housing 300, a motor assembly 100, and a heating assembly 200, all installed inside the housing 300. The housing 300 has a perforated hot air vent 310, which connects to an air outlet 213. Hot air flowing from the air outlet 213 is blown onto the fabric surface through the hot air vent 310. Figure 11 From this angle, the hot air vent 310 is located below the air outlet 213.

[0052] Preferably, the area of ​​the hot air vent 310 is larger than the area of ​​the air outlet 213. This arrangement allows the hot air blown onto the fabric surface through the hot air vent 310 to be more evenly distributed over a larger area.

[0053] See Figures 5 to 7 In some embodiments, the outer cover 210 includes an upper cover portion 214 and a lower cover portion 215, which are arranged along a first direction and assembled by a snap-fit ​​structure, forming the aforementioned heating cavity 211. An air inlet 212 is located on the upper cover portion 214, and an air outlet 213 is located on the lower cover portion 215, thus achieving that the air inlet 212 and air outlet 213 are respectively located at both ends of the outer cover 210 along the first direction. In other embodiments, the upper cover portion 214 and the lower cover portion 215 may also be integrated.

[0054] See Figures 5 to 7 ,as well as Figure 11 In some embodiments, the air inlet 212 is located at one end of the outer cover 210 along the second direction, and the air outlet 213 is spaced apart from the air inlet 212 along the second direction, which is perpendicular to the first direction.

[0055] Specifically, the air inlet 212 is located at one end of the upper cover 214 along the second direction, and the air outlet 213 is located on the lower cover 215, spaced apart from the air inlet 212 along the second direction. In the embodiment shown in the attached drawings, the second direction is the length direction of the heating component 200. In the above embodiment, the air outlet 213 and the air inlet 212 are spaced apart along the second direction, which allows the airflow to flow fully through the heater 220, thereby being fully heated, optimizing the heating effect on the blown airflow, making it easier to keep the fabric surface dry, and more effectively inhibiting the growth of mites.

[0056] Preferably, in some embodiments, the air inlet 212 is located at one end of the outer cover 210 along the second direction, and the air outlet 213 is located at the other end of the outer cover 210 along the second direction.

[0057] Specifically, the air inlet 212 is located at one end of the upper cover 214 along the second direction, and the air outlet 213 is located at the other end of the lower cover 215 along the second direction away from the air inlet 212. Alternatively, as shown in the attached figure, the air outlet 213 can be located in the central area of ​​the lower cover 215 along the second direction. In this case, the air outlet 213 and the air inlet 212 are still spaced apart along the second direction.

[0058] See Figures 5 to 7 In some embodiments, the air inlet 212 is located at one end of the outer cover 210 along a third direction, and the air outlet 213 is at least partially located at the other end of the outer cover 210 along a third direction, the third direction being perpendicular to the second direction and the first direction.

[0059] In the embodiment shown in the attached drawings, the third direction refers to the width direction of the heating component 200. The air inlet 212 is located at one end of the upper cover 214 along the third direction, and the air outlet 213 is elongated, almost covering the entire area of ​​the lower cover 215 along the upper third direction. Alternatively, in other embodiments, the entire area of ​​the air outlet 213 may be located at the other end of the lower cover 215 along the upper third direction, away from the air inlet 212.

[0060] This configuration allows the air outlet 213 and the air inlet 212 to be at least partially spaced along a third direction, allowing the airflow to flow fully through the heater 220 and be fully heated, thus optimizing the heating effect on the blown airflow, making it easier to keep the fabric surface dry and more effectively inhibiting the growth of mites.

[0061] See Figures 5 to 7 In some embodiments, the heater 220 is located at least partially in the upstream region of the airflow path near the air inlet 212.

[0062] This configuration allows the airflow entering the heating chamber 211 from the air inlet 212 to flow more concentratedly through the heater 220 before it dissipates, reducing the amount of airflow that reaches the air outlet 213 without passing through the heater 220, thus achieving a better heating effect.

[0063] Furthermore, in some embodiments, the heater 220 is at least partially located within the heating chamber 211 at one end along the second direction near the air inlet 212; the heater 220 is at least partially located within the heating chamber 211 at one end along the third direction near the air inlet 212.

[0064] Preferably, the heater 220 substantially fills the heating chamber 211 along the third direction. This further reduces the airflow that reaches the air outlet 213 without passing through the heater 220, thereby further optimizing the heating effect. "Substantially fills" here means that the ratio of the dimension of the heater 220 along the third direction to the dimension of the heating chamber 211 along the third direction is greater than 70%.

[0065] Similarly, heater 220 substantially fills the heating chamber 211 along the second direction. "Substantially fills" here means that the ratio of the dimension of heater 220 along the second direction to the dimension of heating chamber 211 along the second direction is greater than 70%.

[0066] See Figures 5 to 7 In some embodiments, the cross-sectional area of ​​the air inlet 212 is smaller than the cross-sectional area of ​​the air outlet 213.

[0067] In the above embodiments, when the cross-sectional area of ​​the air inlet 212 is smaller than that of the air outlet 213, the airflow can first gather and then disperse in the heating chamber 211, and fully flow through the heater 220, thereby being fully heated, optimizing the heating effect on the blown airflow, making it easier to keep the fabric surface dry and more effectively inhibiting the growth of mites.

[0068] Preferably, in some embodiments, the ratio of the dimension of the air inlet 212 along a third direction to the dimension of the air outlet 213 along a third direction is a, where 0.2≤a≤0.5.

[0069] Preferably, in some embodiments, the size of the air inlet 212 along the second direction is larger than the size of the air outlet 213 along the second direction.

[0070] When the above size requirements are met, not only can the cross-sectional area of ​​the air inlet 212 be smaller than that of the air outlet 213, but also the airflow inlet 212 being too small will be avoided as much as possible, and the airflow inlet 212 being too large will be too dispersed and not concentrated, thereby further optimizing the heating effect of the airflow flowing through the heating chamber 211.

[0071] See Figures 5 to 7 ,as well as Figure 11 In some embodiments, the heating assembly 200 includes a thermostat 230 installed in the heating chamber 211. The thermostat 230 is in contact with the heater 220 and is used to control the heater 220 to stop heating when the heater 220 exceeds a preset temperature.

[0072] The thermostat 230 is in contact with the heater 220 and the two are communicatively connected. The thermostat 230 can measure the current temperature of the heater 220. The preset temperature can be manually set in advance, for example, the preset temperature is 220 degrees Celsius. When the thermostat 230 detects that the current temperature of the heater 220 exceeds 220 degrees Celsius, it controls the heater 220 to stop heating to prevent danger caused by overheating.

[0073] See Figure 3 , Figure 4 and Figure 11In some embodiments, the motor assembly 100 includes a motor housing 110 and a motor 120 mounted in the motor housing 110. A first outlet 11521 is disposed in the motor housing 110 and is located outside the space where the motor 120 is located along its own axial direction.

[0074] Specifically, the motor 120 has an airflow inlet and an airflow outlet. When the motor 120 is working, under its suction force, external airflow flows in through the airflow inlet and is discharged through the airflow outlet. Figure 11 From this perspective, the airflow outlet on motor 120 is located in the area near its right end, and the first outlet 11521 is located on the right side of the space along the axial direction (left-right direction) of motor 120. That is, the first outlet 11521 is located to the right of the rightmost position of motor 120. This arrangement allows the airflow from the airflow outlet of motor 120 to pass through its axial space more extensively, making more contact with the components of motor 120 for heat exchange, rather than immediately dissipating radially outward after flowing out of the airflow outlet. This allows for more efficient use of the airflow to carry away the heat generated by motor 120, thus improving heat dissipation for motor 120.

[0075] It should be noted that, Figure 11 In the middle, the cables and other components extending from the right end of the motor 120 are not classified as internal structures of the motor 120, that is, the first flow outlet 11521 does not necessarily have to be located to the right of the right end of these cables.

[0076] See Figures 1 to 4 ,as well as Figure 8 In some embodiments, the motor assembly 100 also has a second outlet 11211 that is not connected to the air inlet 212, the second outlet 11211 being used to supply airflow directly to the external environment.

[0077] In the above embodiments, by providing multiple airflow outlets on the motor assembly 100, the airflow from the motor 120 can be diverted and discharged to the external environment, thereby reducing the noise caused by the concentrated discharge of airflow and improving the user experience.

[0078] See Figures 1 to 4 ,as well as Figure 8 In some embodiments, the motor assembly 100 includes a motor housing 110 and a motor 120 mounted in the motor housing 110. The motor housing 110 is provided with a first flow outlet 11521 and a plurality of second flow outlets 11211.

[0079] Specifically, the housing 300 is provided with a hollowed-out cold air vent 320, which is connected to the second flow outlet 11211. The airflow from the second flow outlet 11211 is discharged to the external environment through the corresponding cold air vent 320.

[0080] When the motor 120 is working, external airflow carrying dust and mites is drawn into the dust collection box through the airflow inlet (not shown in the figure) on the casing 300. After being filtered by the dust collection box, the dust and mites are retained inside the dust collection box, while the clean airflow flows through the motor 120. Of the airflow flowing out of the motor 120, part of the airflow flows out through the first outlet 11521 and is heated by the heating chamber 211 before being blown onto the fabric surface through the hot air outlet 310. The other part of the airflow is discharged to the external environment through the second outlet 11211 and the corresponding cold air outlet 320.

[0081] See Figure 3 , Figure 4 and Figure 8 In some embodiments, the motor housing 110 includes an inner housing portion 111 and an outer housing portion 112 connected to each other. The outer housing portion 112 surrounds the outer side of the inner housing portion 111 to form an airflow channel 114 between them. The inner housing portion 111 has a mounting cavity 113 on its inner side, and the motor 120 is mounted in the mounting cavity 113. A second outlet 11211 is opened in the outer housing portion 112 and communicates with the airflow channel 114. The inner housing portion 111 has a notch 11121 communicating with the airflow channel 114 and the mounting cavity 113. The airflow from the motor 120 can flow sequentially through the notch 11121 and the airflow channel 114 to reach the second outlet 11211.

[0082] In the embodiment shown in the attached figure, the outer casing 112 is provided with two second flow outlets 11211, which are respectively located on both sides of the notch 11121. The airflow flowing out of the motor 120 gathers in the mounting cavity 113, and part of the airflow in the mounting cavity 113 flows into the airflow channel 114 from the notch 11121 and is divided into two parts, which flow out from the two second flow outlets 11211 respectively.

[0083] See Figures 8 to 10 In some embodiments, the motor housing assembly 110 includes a base plate 115, an inner shell portion 111 and an outer shell portion 112 are both connected to one side of the base plate 115, the inner side of the inner shell portion 111 and the base plate 115 enclose a mounting cavity 113, and a first outlet 11521 is opened on the base plate 115.

[0084] Specifically, the substrate 115 is generally flat, and both the inner shell 111 and the outer shell 112 are generally annular, both connected to one side of the substrate 115 along its thickness direction. An annular airflow channel 114 is formed between the outer side of the inner shell 111, the inner side of the outer shell 112, and the substrate 115. The first outlet 11521 is opened on the substrate 115. Therefore, of the airflow in the mounting cavity 113, a portion will flow directly out from the first outlet 11521, and another portion will flow into the airflow channel 114 through the notch 11121, and then split into two parts, flowing out from the two second outlets 11211 respectively.

[0085] See Figure 4 ,as well as Figures 8 to 10 Furthermore, in some embodiments, the motor housing assembly 110 includes a side shell 110-a and an end shell 110-b, with the end shell 110-b connected to one end of the side shell 110-a. The side shell 110-a includes a side shell base plate portion 1151, a side shell inner plate 1111, and a side shell outer plate 1121 surrounding the outer side of the side shell inner plate 1111. The end shell 110-b includes an end shell base plate portion 1152, an end shell inner plate 1112, and an end shell outer plate 1122 surrounding the outer side of the end shell inner plate 1112. The side shell base plate portion 1151 and the end shell base plate portion 1152 form a base plate 115, the end shell inner plate 1112 and the side shell inner plate 1111 form an inner shell portion 111, and the end shell outer plate 1122 and the side shell outer plate 1121 form an outer shell portion 112. Two second flow outlets 11211 are symmetrically arranged on the outer plate of the side shell 1121, a notch 11121 is opened on the inner plate of the end shell 1112, and a first flow outlet 11521 is opened on the base plate of the end shell 1152.

[0086] See Figures 1 to 3 In some embodiments, the mite-removing vacuum cleaner includes a housing 300, a motor assembly 100, and a heating assembly 200 installed inside the housing 300. The housing 300 has a hot air vent 310 connected to a first outlet 11521, and two cold air vents 320 correspondingly connected to two second outlets 11211. When the mite-removing vacuum cleaner is in use, the two cold air vents 320 are located at the left and right ends of the housing 300, and the hot air vent 310 is located at the bottom end of the housing 300. Of course, in other embodiments, the vents on the housing 300 may be located in other positions.

[0087] See Figure 1 , Figure 2 and Figure 12 In some embodiments, the mite-removing vacuum cleaner includes a baffle 400, which is detachably mounted at any of the cold air vents 320.

[0088] Specifically, the baffle 400 can be installed using detachable methods such as snap-fit ​​or magnetic attachment. A flip-up cover can be installed on the area where the air vent 320 is located on the casing 300. By flipping up the cover, the baffle 400 can be exposed and removed. When a baffle 400 is installed on one of the air vents 320, that air vent 320 will be blocked, and airflow cannot be discharged. In this way, according to the user's usage habits, the air vent 320 closest to the user can be blocked to prevent airflow from being discharged from that side of the air vent 320 and blowing towards the user, thus affecting the user experience.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0090] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
