Description

Technical Field

[0001] The present invention relates to the technical field of bathroom equipment, and in particular to an automatic defogging bathroom mirror device and a control method thereof. Background Art

[0002] Bathrooms often have mirrors installed. When a mirror fogs up, it's traditionally customary to wipe it with a towel or paper towel to remove the mist. However, this traditional method is not only cumbersome but also ineffective. Currently, some mirrors have a heating film installed on the back, with a touch switch on the mirror to control the opening and closing of the heating film. The heating of the heating film causes the mist on the mirror to evaporate, thereby achieving defogging. However, this defogging method has the following drawbacks: 1. The user needs to manually turn on the defogging function, and it takes a certain amount of time for the mist on the mirror to disappear. The user needs to wait for the defogging to complete before using the mirror, which is time-consuming. 2. Regardless of the degree of fogging, the defogging function often only sets the heating film to heat at the same power, which is energy-wasting. 3. Sometimes users forget to turn off the switch, resulting in a waste of electricity. 4. The user's hands may be wet, and when operating the switch, water stains may be left on the mirror, which can also easily cause the touch switch to malfunction. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an automatic defogger bathroom mirror device. A force-measuring assembly measures the force acting on the mirror, thereby detecting fogging on the mirror. This electrical signal is then fed back to a heating film, which activates heating and achieves automatic defogger. This device avoids the need to manually activate the defogger function and facilitates use.

By judging the change in the force, the fogging condition on the mirror can be obtained, and an electrical signal can be fed back to the heating film to start heating the mirror, causing the heating film to start heating the mirror, thereby causing the water mist on the mirror surface to evaporate, thereby realizing the automatic defogger function, which is beneficial to avoiding the trouble of manually turning on the defogger function.

[0011] According to some embodiments of the present invention, the automatic defogger bathroom mirror device further includes a display screen assembly, wherein the display screen assembly is electrically connected to the heating film and / or the force measuring assembly.

[0012] According to the control method described in the embodiment of the second aspect of the present invention, it is applied to an automatic defogger bathroom mirror device including a mirror, a heating film and a force measuring assembly, the heating film is arranged on the rear side of the mirror and is attached to the back of the mirror, the force measuring assembly is electrically connected to the heating film, the mirror can be installed in an external installation environment through the force measuring assembly, the force measuring assembly can measure the weight of the mirror and feedback an electrical signal to the heating film, and the heating film can heat the mirror, the control method includes: measuring the force acting on the force measuring assembly by the mirror through the force measuring assembly to obtain the force F; judging whether the force F is greater than or equal to a preset value, when the force F is greater than or equal to the preset value, starting the heating film to make the heating film heat the mirror, otherwise re-measuring and obtaining a new force F.

[0013] According to the control method described in the embodiment of the present invention, it has at least the following beneficial effects: the force acting on the mirror on the force measuring component is measured by the force measuring component to obtain the force F. When fogging occurs on the mirror surface, the water mist adhering to the mirror surface will increase the weight of the mirror, thereby causing the force F acting on the force measuring component to change. The fogging condition on the mirror can be obtained by judging whether the force F is greater than or equal to a preset value, and an electrical signal is fed back to the heating film. When the force F is greater than or equal to the preset value, the heating film is started to heat the mirror, causing the water mist on the mirror surface to evaporate, thereby realizing the automatic defogger function, which is beneficial to avoid the trouble of manually turning on the defogger function. When the mirror surface fogs up, the defogger function is started to perform defogger, which is convenient for reducing the user's waiting time, and is beneficial for avoiding problems such as water stains caused by wet hands touching the mirror surface and malfunction of the touch switch, and is easy to use.

If the force F is greater than or equal to the preset value F3, start the heating film and make the heating film run at the preset heating power W3 for heating; otherwise, start the heating film and make the heating film run at the preset heating power W2 for heating.

[0016] According to some embodiments of the present invention, after the heating film operates at a preset heating power for a preset time t, a new force F is remeasured and obtained, and the force F is compared with a preset value corresponding to the preset heating power at which the heating film operates.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that if orientation descriptions are involved, the orientations or positional relationships indicated, such as up, down, front, back, left, and right, are based on the orientations or positional relationships shown in the accompanying drawings. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0028] If the first and second are described, they are only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Reference Figure 1 、 Figure 2 and Figure 3 An automatic defogger bathroom mirror device includes a mirror 100, a heating film 200 and a force measuring assembly 300. The heating film 200 is arranged on the rear side of the mirror 100 and is attached to the back of the mirror 100. The force measuring assembly 300 is electrically connected to the heating film 200. The mirror 100 can be installed in an external installation environment through the force measuring assembly 300. The force measuring assembly 300 can measure the magnitude of the force applied by the mirror 100 to the force measuring assembly 300 and feed back an electrical signal to the heating film 200. The heating film 200 can heat the mirror 100.

[0031] It is understandable that if Figure 1 、 Figure 2 and Figure 3As shown, when in use, the mirror 100 can be installed in an external installation environment such as a wall or a bathroom cabinet through the force measuring component 300. Since the force measuring component 300 serves as a connecting structure between the mirror 100 and the wall, the mirror 100 will generate a force on the force measuring component 300 under the action of gravity. The force acting on the force measuring component 300 by the mirror 100 is measured by the force measuring component 300. When fogging occurs on the mirror surface, the water mist adhering to the mirror surface will increase the weight of the mirror 100, thereby causing the force acting on the force measuring component 300 to change. By judging the change in the force, the fogging condition on the mirror 100 can be obtained, and an electrical signal can be fed back to the heating film 200, so that the heating film 200 starts to heat the mirror 100, causing the water mist on the mirror surface to evaporate, thereby realizing an automatic defogger function, which is beneficial to avoid the trouble of manually turning on the defogger function. When the mirror surface fogs, the defogger function is activated to perform defogger, which is convenient for reducing the user's waiting time and helping to avoid problems such as water stains caused by wet hands touching the mirror surface and malfunction of the touch switch, making it easy to use.

[0032] In actual application, the specific structure of the force measuring component 300 can be set accordingly according to actual use needs, which will not be described in detail here, but will be described in detail below; since the specific structure of the heating film 200 of the embodiment of the present invention is known to ordinary technicians in this field, it will not be described in detail here.

[0033] In some embodiments, the force measuring assembly 300 includes a mounting base 310 and a pressure sensor 320 . The mounting base 310 is disposed on the lower side of the mirror 100 . The pressure sensor 320 is disposed on the mounting base 310 . The lower side of the mirror 100 abuts against the pressure sensor 320 .

[0034] It is understandable that if Figure 1 、 Figure 2 and Figure 3 As shown, the force measuring assembly 300 includes a mounting base 310 and a pressure sensor 320. When in use, the mounting base 310 is installed in an external installation environment such as a wall or a bathroom cabinet, the mirror 100 is set on the mounting base 310, and the lower side of the mirror 100 is abutted against the pressure sensor 320. Under the action of gravity, the mirror 100 exerts pressure on the pressure sensor 320. The pressure value is detected by the pressure sensor 320, so that the force exerted by the mirror 100 on the force measuring assembly 300 can be measured. Its structure is simple and reasonable, and it is easy to use.

[0035] In actual application, in addition to the above structure, the force measuring component 300 may also include a mounting base 310 and a tension sensor. The mounting base 310 is arranged above the mirror 100, and the tension sensor is arranged on the mounting base 310. The upper side of the mirror 100 is connected to the tension sensor through a traction member such as a rope, thereby realizing the lifting of the mirror 100. Under the action of gravity, the mirror 100 exerts a tension on the tension sensor. The tension value is detected by the tension sensor, so that the force exerted by the mirror 100 on the force measuring component 300 can be measured. The specific setting can be made according to actual usage needs.

[0036] In some embodiments, a first slot 311 is provided on the mounting base 310 , the pressure sensor 320 is disposed on a lower slot wall of the first slot 311 , and the mirror 100 is partially inserted into the first slot 311 .

[0037] It is understandable that if Figure 1 、 Figure 2 and Figure 3 As shown, the pressure sensor 320 is disposed on the lower wall of the first slot 311. During use, the lower side of the mirror 100 is inserted into the first slot 311. Providing the first slot 311 and placing the pressure sensor 320 on the lower wall of the first slot 311 helps protect the pressure sensor 320, reduces the possibility of foreign objects contacting the pressure sensor 320, and helps improve pressure measurement accuracy and reliability. In actual use, the specific structure of the first slot 311 can be set accordingly according to actual use needs and is not limited here.

[0038] In some embodiments, the automatic defogger bathroom mirror device also includes an auxiliary bracket 400, which is provided with a second slot 410. A first magnetic member 420 is provided on the front and rear walls of the second slot 410. The side of the mirror 100 is inserted into the second slot 410 and a second magnetic member 110 is provided on the front and rear sides of the mirror 100. A magnetic repulsion force can be generated between the first magnetic member 420 and the second magnetic member 110, so that the side of the mirror 100 can be magnetically suspended between the front and rear walls of the second slot 410.

[0039] It is understandable that if Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, during use, the auxiliary bracket 400 is mounted on an external installation environment such as a wall or bathroom cabinet. First magnetic members 420 are provided on the front and rear walls of the second slot 410, and second magnetic members 110 are provided on the front and rear sides of the side of the mirror 100. The side of the mirror 100 is inserted into the second slot 410 of the auxiliary bracket 400. The magnetic repulsion generated between the first magnetic member 420 and the second magnetic member 110 balances the front and rear forces of the mirror 100, allowing the side of the mirror 100 to be magnetically suspended between the front and rear walls of the second slot 410. This prevents the front and rear sides of the mirror 100 from contacting the outside world, effectively placing pressure on the mirror 100 on the pressure sensor 320 of the mounting base 310, and improving the accuracy of detecting whether water mist is attached to the mirror surface, thereby facilitating use. In actual application, the specific structure of the auxiliary bracket 400 can be varied accordingly according to actual needs.

[0040] In some embodiments, four auxiliary brackets 400 are provided, two of the four auxiliary brackets 400 are located at the upper part of the mirror 100 and are respectively arranged on the left and right sides of the mirror 100, and the other two auxiliary brackets 400 are located at the lower part of the mirror 100 and are respectively arranged on the left and right sides of the mirror 100.

[0041] It is understandable that if Figure 1 and Figure 2 As shown, two auxiliary brackets 400 are located on the upper portion of the mirror 100 and are respectively provided on the left and right sides of the mirror 100, and two auxiliary brackets 400 are located on the lower portion of the mirror 100 and are respectively provided on the left and right sides of the mirror 100. This allows the front and rear position of the mirror 100 to be restricted from four compass points, facilitating the fixing of the mirror 100 for ease of use. In actual use, two auxiliary brackets 400 can also be provided, one on each side of the mirror 100. The specific number of auxiliary brackets 400 provided can be varied accordingly based on actual use needs.

[0042] In some embodiments, the automatic defogger bathroom mirror device further comprises a display screen assembly 500, which is electrically connected to the heating film 200 and / or the force measuring assembly 300. Figure 1As shown, a display screen assembly 500 is provided on the force measuring assembly 300. The force measuring assembly 300 may also include control components such as a circuit board and a single chip microcomputer. The control component is electrically connected to the heating film 200 and the pressure sensor 320. The display screen assembly 500 can be electrically connected to the control component to achieve electrical connection with the heating film 200 and the force measuring assembly 300. The pressure sensor 320 feeds back the force measurement situation to the control component, and the control component controls the opening and closing of the heating film 200. By setting up the display screen assembly 500, it is convenient to display the working status of the heating film 200 or the fogging situation of the mirror 100, so that the user can understand the working status of the present invention and it is easy to use. In actual application, the display screen assembly 500 can be set accordingly according to actual use needs. Since the specific structure of the display screen assembly 500 of the embodiment of the present invention is known to ordinary technicians in this field, it will not be described in detail here.

[0043] According to the control method of the second aspect of the present invention, it is applied to an automatic defogger bathroom mirror device including a mirror 100, a heating film 200 and a force measuring assembly 300. The heating film 200 is arranged on the rear side of the mirror 100 and is attached to the back of the mirror 100. The force measuring assembly 300 is electrically connected to the heating film 200. The mirror 100 can be installed in an external installation environment through the force measuring assembly 300. The force measuring assembly 300 can measure the weight of the mirror 100 and feedback an electrical signal to the heating film 200. The heating film 200 can heat the mirror 100. The control method includes: measuring the force acting on the force measuring assembly 300 by the force measuring assembly 300 to obtain the force F; judging whether the force F is greater than or equal to a preset value. When the force F is greater than or equal to the preset value, starting the heating film 200 so that the heating film 200 heats the mirror 100; otherwise, re-measuring and obtaining a new force F.

[0044] The force F acting on the mirror 100 is measured by the force measuring component 300 to obtain the force F. When fogging occurs on the mirror surface, the water mist adhering to the mirror surface will increase the weight of the mirror 100, thereby causing the force F acting on the force measuring component 300 to change. A preset value is set according to the area size of the mirror 100 and other conditions. The fogging condition on the mirror 100 can be obtained by judging whether the force F is greater than or equal to the preset value, and an electrical signal is fed back to the heating film 200. If the force F is less than the preset value, that is, the mirror 100 has not reached the condition where the defogging function needs to be activated, the new force F is measured again and the judgment is repeated. When the force F is greater than or equal to the preset value, the heating film 200 is activated to heat the mirror 100, causing the water mist on the mirror surface to evaporate, thereby realizing the automatic defogging function, which is beneficial to avoid the trouble of manually turning on the defogging function. When the mirror surface fogs up, the defogging function is activated to perform defogging, which is convenient for reducing the user's waiting time and helping to avoid problems such as water stains caused by wet hands touching the mirror surface and malfunction of the touch switch, making it easy to use. In actual application, there may be multiple preset values, and their specific values ​​may be set accordingly according to specific circumstances.

[0045] In some embodiments, the preset values ​​include F1 and F2, the preset value F1 is less than the preset value F2, the heating film 200 can operate for heating at a preset heating power, the preset heating power includes W1 and W2, the preset value F1 corresponds to the preset heating power W1, the preset value F2 corresponds to the preset heating power W2, and the preset heating power W2 is greater than the preset heating power W1; after obtaining the applied force F, first determine whether the applied force F is greater than or equal to the preset value F1, if the applied force F is greater than or equal to the preset value F1, then determine whether the applied force F is greater than or equal to the preset value F2, otherwise re-measure and obtain a new applied force F; if the applied force F is greater than or equal to the preset value F2, then start the heating film 200 and make the heating film 200 operate for heating at the preset heating power W2, otherwise start the heating film 200 and make the heating film 200 operate for heating at the preset heating power W1.

[0046] It is understandable that, referring to Figure 5The preset values ​​include F1 and F2. The preset value F1 is smaller than the preset value F2, so that the present invention has two defogger gears and corresponding preset heating powers are set. The preset value F1 corresponds to the preset heating power W1, and the preset value F2 corresponds to the preset heating power W2. The preset heating power W2 is greater than the preset heating power W1. During operation, after obtaining the applied force F, it is first determined whether the applied force F is greater than or equal to the preset value F1, that is, the judgment is first made relative to the smaller preset value. If the applied force F is greater than or equal to the preset value F1 and less than the preset value F2, that is, the degree of fogging on the mirror 100 is relatively light, the heating film 200 is started and the heating film 200 is heated at the preset heating power W1; if the applied force F is greater than or equal to the preset value F2, that is, the degree of fogging on the mirror 100 is relatively heavy, the heating film 200 is started and the heating film 200 is heated at the preset heating power W2; if the applied force F is less than the preset value F1, the applied force F is re-measured and a new applied force F is obtained, and the detection and judgment are repeated. By setting two preset values ​​and correspondingly setting two preset heating powers, the heating power is adjusted according to the range of the obtained force F, that is, high power demisting is used if the fog is severe, and low power demisting is used if the fog is light. This is beneficial to shorten the demisting time of the mirror 100, improve the demisting efficiency of the mirror 100, and reduce the demisting power consumption of the mirror 100.

[0047] In actual application, the detection and acquisition of the force F can be performed at intervals or continuously. The preset values ​​F1, F2 and the preset heating powers W1, W2 can be set accordingly according to actual needs and are not limited here.

[0048] In some embodiments, the preset value also includes F3, the preset value F2 is less than the preset value F3, the preset heating power also includes W3, the preset value F3 corresponds to the preset heating power W3, and the preset heating power W3 is greater than the preset heating power W2; after determining that the force F is greater than or equal to the preset value F2, determine whether the force F is greater than or equal to the preset value F3. If the force F is greater than or equal to the preset value F3, start the heating film 200 and make the heating film 200 run at the preset heating power W3 for heating; otherwise, start the heating film 200 and make the heating film 200 run at the preset heating power W2 for heating.

[0049] It is understandable that referring to Figure 5The preset values ​​include F1, F2, and F3. The preset value F2 is less than the preset value F3, and the preset value F3 corresponds to the preset heating power W3. The preset heating power W3 is greater than the preset heating power W2, so that the present invention has three defogger gears. During operation, after determining that the applied force F is greater than or equal to the preset value F2, it is determined whether the applied force F is greater than or equal to the preset value F3. If the applied force F is greater than or equal to the preset value F2 and less than the preset value F3, the heating film 200 is activated and heated at the preset heating power W2, and the heating film 200 is operated in the second gear. If the applied force F is greater than or equal to the preset value F3, the heating film 200 is activated and heated at the preset heating power W3, and the heating film 200 is operated in the third gear. By setting three gears, it is possible to further adapt to different mirror fogging conditions and improve adaptability.

[0050] In actual application, the preset value F3 and the preset heating power W3 can be set according to actual use needs. The preset values ​​can also include four, five or more, and the size, difference, etc. between them can also be set according to actual use needs, which will not be elaborated here.

[0051] In some embodiments, after the heating film 200 operates at a preset heating power for a preset time t, a new force F is remeasured and obtained, and the force F is compared with a preset value corresponding to the preset heating power at which the heating film 200 operates. Based on the result of the judgment and comparison, the heating film 200 is controlled to operate at the corresponding preset heating power until the force F is less than the preset value F1, at which point the heating film 200 is controlled to stop working.

[0052] It is understandable that, referring to Figure 5 When the fogging condition of the mirror 100 is determined and the heating film 200 is started to run at the preset heating power for the preset time t, the new force F is re-measured and obtained, and the preset value corresponding to the preset heating power run by the force F heating film 200 is judged and compared to determine whether the fogging condition of the mirror 100 changes after running for the preset time t. Then, according to the result of the judgment and comparison, the heating film 200 is controlled to run at the corresponding preset heating power until the force F is less than the preset value F1, and the heating film 200 is controlled to stop working.

[0053] Specifically, refer to Figure 5For example, after the heating film 200 has been running for a preset time t at the preset heating power W3, a new applied force F is measured again and obtained, and the applied force F is compared with the preset value corresponding to the preset heating power W3, that is, compared with the preset value F3. If the applied force F is greater than or equal to the preset value F3, that is, the mirror surface is still severely fogged, the heating film 200 continues to be operated at the preset heating power W3; if the applied force F is less than the preset value F3, that is, the fogging of the mirror surface has become lighter, the operating power is reduced, and the heating film 200 is operated for heating at the preset heating power W2; after the heating film 200 has been running for a preset time t at the preset heating power W2, a new applied force F is measured again and obtained, and the applied force F is compared with the preset value corresponding to the preset heating power W2, that is, compared with the preset value F2. If the applied force F is greater than or equal to the preset value F2, that is, the mirror surface is still moderately fogged, the heating film 200 continues to operate at the preset heating power W2; if the applied force F is less than the preset value F2, that is, the fogging of the mirror surface has become lighter, the operating power is further reduced, and the heating film 200 is heated at the preset heating power W1; after the heating film 200 has been running at the preset heating power W1 for the preset time t, the new applied force F is re-measured and obtained, and the applied force F is compared with the preset value corresponding to the preset heating power W1, that is, compared with the preset value F1. If the applied force F is greater than or equal to the preset value F1, that is, the mirror surface is still slightly fogged, the heating film 200 continues to operate at the preset heating power W1; if the applied force F is less than the preset value F1, that is, the mirror surface has been defogged, the heating film 200 is controlled to stop working.

[0054] Through the above-described method, the heating power of the heating film 200 dynamically changes as the mirror 100 defogs, switching to different heating powers in response to different levels of fogging. This helps reduce energy consumption and improves its energy-saving performance. After defogging is completed, the heating film 200 automatically turns off, providing convenience for users. In actual applications, the preset time t can be set accordingly according to actual needs and is not limited here.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the spirit of the present invention.
