Description

Technical Field

[0001] The present application relates generally to humidifiers. Background Art

[0002] A humidifier is an electrical appliance that increases the humidity of an environment. At least some types of humidifiers may include a wet curtain as a water-absorbing medium, and the humidifier increases the relative humidity of the air by forcing air through the wet curtain, such as by a fan. In order to increase the surface area and improve the water exchange efficiency, the wet curtain usually adopts a porous water-absorbing material (e.g., cotton or foam material), a pleated structure, and / or a corrugated surface.

[0003] After the wet curtain absorbs water for a period of time, it will precipitate and accumulate high concentrations of minerals, such as calcium and magnesium. This is especially significant in areas with hard water. These sediments will affect the normal operation of the wet curtain. In addition, microorganisms such as bacteria and viruses are easily accumulated in the wet curtain, affecting the health of users. Therefore, users need to clean the wet curtain regularly.

[0004] Manually cleaning the wet curtain puts a lot of pressure on users to use the humidifier. For example, users may need to take out the wet curtain and soak it in an acidic solution such as citric acid to dissolve the minerals. However, improper cleaning methods can easily damage the wet curtain, cause harm to the human body (e.g., skin, respiratory tract, etc.), and pollute the environment. In addition, the characteristics of the wet curtain's material, structure, and surface also make it difficult for users to achieve good results by manually cleaning the wet curtain.

[0022] Figure 1 1 shows a schematic cross-sectional view of a humidifier 100 according to an exemplary aspect of the present disclosure. Figure 1 As shown in FIG. 1 , the humidifier 100 includes a main body, a wet curtain 110, a water tank 120, an ultrasonic generator 130 and other components (not specifically shown). The main body may include a housing and a fan component.

[0023] According to an exemplary embodiment, the wet pad 110 is placed in the water tank 120 and absorbs and stores water in the water tank. Figure 1 The exemplary humidifier 110 shown in the figure may include a fan assembly. According to an exemplary embodiment, the fan assembly may be, for example, located above the wet curtain 110 and draws axial air upward through an impeller, but the present disclosure is not limited thereto. For example, the fan assembly may also draw air laterally. The air humidified by the wet curtain 110 enters the external environment through the outlet above, thereby achieving the effect of humidifying the environment.

[0024] The exemplary humidifier 100 according to the present disclosure also incorporates an ultrasonic generator 130. It should be noted that although Figure 1 The exemplary ultrasonic generator 130 is shown as being disposed at the bottom of the water tank 120, but the present disclosure is not limited thereto. The number of the ultrasonic generator 130 may include a single one or a plurality of them.

[0025] According to an exemplary embodiment, the ultrasonic generator 130 may be mounted using welding, or may be mounted using a screw and nut fastening method.

[0026] According to at least some alternative embodiments, the ultrasonic generator 130 can be disposed on the side (including one side or multiple sides) of the water tank 120, or around the side of the water tank 120, or at other locations of the water tank 120 that allow ultrasonic waves to enter the water without blocking the air passage. According to some further embodiments, the ultrasonic generator 130 can be disposed at various combinations of the above items.

[0027] According to an exemplary embodiment, when the ultrasonic generator 130 is activated, the ultrasonic generator 130 emits ultrasonic waves and enters the water in the water tank 120. The ultrasonic waves are propagated through water as a medium, so that the microbubbles of the water in the water tank 120 can keep vibrating under the action of the sound waves, destroying the adsorption between the dirt and the wet curtain 110 and the inner surface of the water tank 120, causing fatigue damage of the dirt and being peeled off. The dirt may include, for example, minerals (e.g., calcium and magnesium, etc.) precipitated and accumulated on the walls of the wet curtain 110 and the water tank 120 and / or microorganisms such as bacteria and viruses. The dirt that falls off from the walls of the wet curtain 110 and the water tank 120 sinks to the bottom of the water tank 120 and can be cleaned up when the water tank 100 is cleaned.

[0028] According to the solution of the present disclosure, it is not necessary to add any cleaning agent, solvent, or acid / alkaline substance into the water tank 120 to help remove dirt on the wet curtain, thereby ensuring user health and environmental friendliness.

[0029] According to an exemplary embodiment, the ultrasonic generator 130 can clean the wet curtain 110 while the humidifier 100 is humidifying without affecting the normal humidification function of the humidifier 100. The ultrasonic generator 130 can also clean the wet curtain 110 when the humidifier 100 is not operating.

[0030] According to an exemplary embodiment, the humidifier 100 may be opened to remove the wet curtain 110 from the water tank 120 .

[0031] According to an exemplary embodiment, a control circuit (not shown) may be provided on the water tank to control the ultrasonic generator 130. This will be described below in conjunction with Figure 6 Give a description.

[0032] According to some exemplary embodiments, an electrical connection component (e.g., an electrical contact, etc.) may be provided on the water tank 100 (e.g., the upper edge of the water tank 100, etc.), so that when the water tank 100 is properly placed in the humidifier and the humidifier is tightly closed, a loop is formed between the electrical connection component on the water tank 100 and the main body of the humidifier 100, so that the control circuit on the water tank 100 is electrically connected to the main body of the humidifier 100. On the other hand, the electrical connection component is connected to the ultrasonic generator. Thus, the user can control the ultrasonic generator through the control (e.g., panel) on the humidifier 100 to clean the wet curtain, and the ultrasonic generator and the control circuit can be powered from the main body of the humidifier 100.

[0033] According to some exemplary embodiments, the control circuit on the water tank 100 may include a wireless signal receiving function, module, or subcircuit to wirelessly receive a signal to control the cleaning of the wet curtain 110. According to some exemplary embodiments, the water tank 100 may also include a battery box (not shown) to power the ultrasonic generator.

[0034] According to some exemplary embodiments, the user can control the cleaning of the wet curtain through a panel on the main body of the humidifier 100 and / or a remote controller, which will be described below in conjunction with Figure 6 Further description.

[0035] Figure 2 A schematic diagram of an automatic cleaning scheme for a humidifier wet curtain according to an exemplary aspect of the present disclosure is shown. Figure 2 In the automatic cleaning solution of the humidifier wet curtain, the ultrasonic generator 130 can be installed at the bottom (e.g., the center) of the water tank 120, and the ultrasonic wave propagates from bottom to top and cleans the wet curtain 110 and / or the side wall of the water tank 120.

[0036] exist Figure 2 In the automatic cleaning solution of the humidifier wet curtain, preferably, the water level in the water tank 120 can be maintained at at least half or above.

[0037] According to an exemplary embodiment, in order to achieve a better wet curtain cleaning effect, after the ultrasonic cleaning is completed, the humidifier 200 can be turned on, and the wet curtain can be turned upside down and placed in the water tank 120, and the ultrasonic generator 130 can be turned on again to clean the wet curtain 110. Thus, only a simple upside-down operation is required to quickly, efficiently and with low energy consumption to clean the wet curtain 110 in all directions.

[0038] Figure 3 A schematic diagram of an automatic cleaning scheme for a humidifier wet curtain according to an exemplary aspect of the present disclosure is shown. Figure 3In the automatic cleaning solution of the humidifier wet curtain, the ultrasonic generator 130 can be installed on the side of the water tank 120 (for example, in the lower middle part of the side wall), and the ultrasonic wave propagates from the side wall to the opposite side and cleans the wet curtain 110 and / or the side wall of the water tank 120.

[0039] exist Figure 3 In the automatic cleaning scheme of the humidifier wet curtain, preferably, the water level in the water tank 120 can be maintained at at least half or above. According to an exemplary embodiment, in order to achieve a better wet curtain cleaning effect, after the ultrasonic cleaning is completed, the humidifier 200 can be turned on, and the wet curtain can be turned upside down and placed in the water tank 120, and the ultrasonic generator 130 can be turned on again to clean the wet curtain 110. Thus, only a simple upside-down operation is required to quickly, efficiently and with low energy consumption to clean the wet curtain 110 in all directions.

[0040] Figure 4 A schematic diagram of an automatic cleaning scheme for a humidifier wet curtain according to an exemplary aspect of the present disclosure is shown. Figure 4 In the automatic cleaning scheme of the humidifier wet curtain, one of the ultrasonic generators 130 can be installed on the side of the water tank 120 (for example, in the lower middle of the side wall), and the other ultrasonic generator 130 can be installed on the opposite side of the water tank 120, and the ultrasonic wave propagates from both sides to the opposite side and cleans the wet curtain 110 and / or the side wall of the water tank 120.

[0041] exist Figure 4 In the automatic cleaning scheme of the humidifier wet curtain, preferably, the water level in the water tank 120 can be maintained at at least half or above. According to an exemplary embodiment, in order to achieve a better wet curtain cleaning effect, after the ultrasonic cleaning is completed, the humidifier 200 can be turned on, and the wet curtain can be turned upside down and placed in the water tank 120, and the ultrasonic generator 130 can be turned on again to clean the wet curtain 110. Thus, only a simple upside-down operation is required to quickly, efficiently and with low energy consumption to clean the wet curtain 110 in all directions.

[0042] In addition, since the double-sided ultrasonic generator 130 is used, the power of a single ultrasonic generator 130 can be reduced and a more uniform cleaning effect can be provided.

[0043] Although the above combination Figures 2 to 4 The automatic cleaning scheme of the humidifier wet curtain according to various exemplary aspects of the present disclosure is shown and explained, but it can be understood by those skilled in the art that the present disclosure is not limited to the scheme shown, but can include other schemes that can be obtained on the basis of the present disclosure. For example, a combination of a bottom ultrasonic generator and a side ultrasonic generator can be used. For another example, more than two side ultrasonic generators can be used, and so on.

[0044] Figure 5 FIG. 5 shows a schematic diagram of an ultrasonic generator 500 according to an exemplary aspect of the present disclosure. Figure 5 As shown in FIG. 5 , an exemplary ultrasonic generator 500 may include a driving circuit (not shown), an electrode 502, a piezoelectric element 504, and a vibration system. Figure 5 In the exemplary embodiment shown in , the vibration system may include mass blocks M1 and M2, wherein the mass block M1 may be coupled to an output surface 508 (e.g., a bottom surface or a side surface of a water tank) via a coupling member 506, and the mass block M2 may be fastened to the mass block M1 via a compression bolt 512. Two piezoelectric elements 504 are inserted between the mass blocks M1 and M2, and the piezoelectric elements 504 are insulated from the compression bolt 512 via an insulating member 510.

[0045] According to an exemplary embodiment, when a driving circuit (not shown) applies an alternating voltage signal to the piezoelectric element 504 through the electrode 502, the piezoelectric element 504 undergoes a volume change (e.g., a telescopic deformation) in an electric field / magnetic field due to electrostriction or magnetostriction and causes vibration. This vibration is transmitted to the output surface 508 of the ultrasonic generator 500, thereby generating an ultrasonic wave 514. In an embodiment of the present disclosure, the generated ultrasonic wave enters the water in the water tank and propagates through the water as a medium to clean the wet curtain.

[0046] Despite the combination Figure 5 A specific type of ultrasonic generator 500 is described, but one of ordinary skill in the art will appreciate that the present disclosure is not limited to the implementation and type of the specific ultrasonic generator 500, but may include various types of ultrasonic generators of prior art or future technology.

[0047] Figure 6 6 shows a block diagram of an ultrasonic generator control circuit 600 according to an exemplary aspect of the present disclosure. According to an exemplary embodiment, the ultrasonic generator control circuit 600 may include, but is not limited to, an instruction receiving module 602, a power supply module 604, and an ultrasonic generator controller 606. According to some embodiments, the ultrasonic generator control circuit 600 may also optionally include a water level detection module 608. According to an exemplary embodiment, the ultrasonic generator control circuit 600 may be mounted on a water tank.

[0048] According to some exemplary embodiments, the instruction receiving module 602 may receive instructions for controlling the ultrasonic generator. According to some exemplary embodiments, the instruction receiving module 602 may receive instructions from the main body of the humidifier (e.g., its user panel) through wired communication. According to exemplary embodiments, the wired communication may be performed by, for example, combining the above Figure 1The electrical connection components on the water tank 100 described above are implemented. When the water tank is correctly placed in the humidifier and the humidifier is tightly closed, a loop is formed between the electrical connection components on the water tank and the main body of the humidifier, so that the ultrasonic generator control circuit 600 is electrically connected to the main body of the humidifier. On the other hand, the electrical connection components are connected to the ultrasonic generator. Thus, the user can send instructions to control the ultrasonic generator to clean the wet curtain through the control (e.g., panel) on the humidifier.

[0049] According to some exemplary embodiments, the instruction receiving module 602 can receive instructions from the remote controller via wireless communication. According to exemplary embodiments, the wireless communication can be implemented by, for example, Bluetooth, wifi, infrared or other protocols. Thus, the user can send instructions to control the ultrasonic generator to clean the wet curtain via controls (e.g., a panel) on the humidifier.

[0050] According to some exemplary embodiments, the instruction for controlling the ultrasonic generator to clean the wet curtain may include controlling a switch of the ultrasonic generator, an intensity of the ultrasonic generator, a mode of the ultrasonic generator, a working time of the ultrasonic generator, and the like.

[0051] According to some exemplary embodiments, the power supply module 604 may obtain power and provide the ultrasonic generator with the electrical energy required for its operation.

[0052] According to some exemplary embodiments, power supply can be provided by, for example, combining the above Figure 1 The electrical connection components on the water tank 100 described above are implemented. When the water tank is correctly placed in the humidifier and the humidifier is tightly closed, a loop is formed between the electrical connection components on the water tank and the main body of the humidifier, so that the ultrasonic generator control circuit 600 is electrically connected to the main body of the humidifier. On the other hand, the electrical connection components are connected to the ultrasonic generator. As a result, the power supply module 604 can obtain power from the humidifier main body and provide the ultrasonic generator with the electrical energy required for its operation.

[0053] According to such exemplary embodiments, the power module 604 can detect whether the water tank is properly placed in the humidifier and whether the humidifier is properly closed, and can provide this information to the ultrasonic generator controller 606.

[0054] According to some exemplary embodiments, power supply may also be achieved by, for example, a battery box provided on the water tank.

[0055] According to some exemplary embodiments, the ultrasonic generator controller 606 may control the ultrasonic generator according to the instruction received by the instruction receiving module 602 for controlling the ultrasonic generator to clean the wet curtain.

[0056] According to an exemplary embodiment, the ultrasonic generator controller 606 may include one or more of the following or any combination thereof: a switch control module; an intensity control module; a mode control module; and a timing module.

[0057] According to an exemplary embodiment, the switch control module can be used to control the on or off of the ultrasonic generator based on the signal provided by the instruction receiving module 602 or the pre-programmed mode in the mode control module. According to some exemplary embodiments, when the water tank is correctly placed in the humidifier and the humidifier is tightly closed, a loop is formed between the electrical connection component on the water tank and the main body of the humidifier, so that the control circuit on the water tank is electrically connected to the main body of the humidifier 100. On the other hand, the electrical connection component is connected to the ultrasonic generator. At this time, the power supply module 604 provides the signal to the ultrasonic generator 606, and the switch control module enables the ultrasonic generator based on the signal. Otherwise, the switch control module disables the ultrasonic generator.

[0058] According to an exemplary embodiment, the intensity control module can be used to control the intensity of the ultrasonic wave emitted by the ultrasonic generator. The intensity of the ultrasonic generator may include one or more ultrasonic wave intensities for the user to select. For example, the user may issue an instruction to increase or decrease the ultrasonic wave intensity, or may issue an instruction to directly use a certain ultrasonic wave intensity, and so on.

[0059] According to an exemplary embodiment, the mode control module can be used to control the working mode of the ultrasonic generator. The mode of the ultrasonic generator may include, for example, an automatic mode and a manual mode. The automatic mode may include one or more automatic cleaning modes set at the factory or one or more automatic cleaning modes defined by the user. According to an exemplary embodiment, the mode of the ultrasonic generator may include an automatic timing cleaning mode. For example, the automatic timing cleaning mode may include a periodic cleaning mode. For another example, the timing cleaning mode may include a cleaning mode of the fixed time (for example, during a period of low electricity prices). The above are only some examples and do not limit the scope of the present disclosure.

[0060] According to an exemplary embodiment, the timing module can be used to control the working time of the ultrasonic generator. The working time of the ultrasonic generator may include a working cycle, a working time, and / or a working period, etc. For example, the working cycle of the ultrasonic generator may include, for example, daily cleaning, every other day cleaning, every few days cleaning, every week, every other week cleaning, etc. For example, the working time of the ultrasonic generator may include a set number of minutes, etc. For example, the working period of the ultrasonic generator may include starting at present, starting at a fixed time (e.g., 10:00 pm), etc.

[0061] According to some exemplary embodiments, the optional water level detection module 608 can be used to detect the water level in the water tank. As can be seen, when the mode control module includes an automatic timed cleaning mode, the water level detection module 608 can detect the water level and provide the information to the ultrasonic generator controller 606.

[0062] According to some exemplary embodiments, when the mode control module includes an automatic timed cleaning mode, the timing module in the ultrasonic generator controller 606 can determine that the appointed time has arrived. At this time, the power supply module 604 can detect whether the water tank is correctly placed in the humidifier and whether the humidifier is tightly closed, and provide this information to the ultrasonic generator controller 606. On the other hand, the water level detection module 608 can detect whether the water level reaches or exceeds the minimum threshold, and provide this information to the ultrasonic generator controller 606.

[0063] According to some exemplary embodiments, the ultrasonic generator controller 606 determines whether to disable or enable the ultrasonic generator based on information from the power module 604 and the water level detection module 608. For example, when the power module 604 determines that the water tank has been correctly placed in the humidifier and the humidifier has been tightly closed, and the water level detection module 608 determines that the water level in the water tank has reached or exceeded the minimum threshold, the ultrasonic generator controller 606 enables the ultrasonic generator. At this time, the mode control module in the ultrasonic generator controller 606 can control the ultrasonic generator to clean the wet curtain according to the pre-programmed automatic timed cleaning mode.

According to an exemplary embodiment, determining the water level may include determining whether the water level in the water tank exceeds a minimum threshold. According to some exemplary embodiments, the minimum threshold may include a water level of half the height of the water tank.

[0066] According to an exemplary embodiment, determining the water level may further include, when it is determined that the water level in the water tank is less than the minimum threshold, adding water to the water tank so that the water level reaches or exceeds the minimum threshold. According to other exemplary embodiments, when it is determined that the water level is less than the minimum threshold, the user may be prompted to this situation by an indicator light or a buzzer on the panel of the humidifier. According to some exemplary embodiments, when it is determined that the water level is less than the minimum threshold, the ultrasonic generator may be disabled. It should be understood that step 702 is not necessary, but is for obtaining a better wet curtain cleaning effect and improving the wet curtain cleaning efficiency.

[0070] According to an exemplary embodiment, activating the ultrasonic generator may include activating the ultrasonic generator through a panel on a humidifier body housing and / or through a remote controller to clean the wet curtain.

[0071] According to other exemplary embodiments, starting the ultrasonic generator may include automatically starting the ultrasonic generator periodically to clean the wet curtain. According to some exemplary embodiments, automatically starting the ultrasonic generator periodically may include, for example, according to the above combination Figure 6 The ultrasonic generator controller 606 described above operates in the automatic timed cleaning mode of the mode control module.

[0072] According to some exemplary embodiments, the power required for the operation of the ultrasonic generator can be obtained from a battery box (if any) included on the water tank.

[0073] At block 706, the wet curtain cleaning method 700 may include stopping the ultrasonic generator. Block 706 stopping the ultrasonic generator may occur automatically after the ultrasonic generator is started at block 704 and the wet curtain is cleaned, without manual control by the user.

[0075] According to an exemplary embodiment, at block 708, the wet curtain cleaning method 700 may include flipping the wet curtain. Flipping the wet curtain may include manual flipping or automatic flipping. Flipping the wet curtain may achieve a better wet curtain cleaning effect. According to some exemplary embodiments, in an embodiment of manual flipping, when the ultrasonic generator is stopped at block 706, the user may be indicated that the wet curtain may be flipped, for example, by an indicator light or a buzzer on the humidifier panel.

[0076] According to an exemplary embodiment, the wet curtain cleaning method 700 may include restarting the ultrasonic generator at block 710. According to an exemplary embodiment, restarting the ultrasonic generator may include automatically performing the restart when the power module detects that the water tank is correctly placed in the humidifier and the humidifier is tightly closed, without manual control by the user.

[0084] The processing system can be configured as a general processing system having one or more microprocessors providing processor functionality and external memory providing at least a portion of the machine-readable medium, all linked together with other supporting circuitry via an external bus architecture. Alternatively, the processing system can be implemented with an ASIC (Application Specific Integrated Circuit) with a processor, bus interface, user interface (in the case of an access terminal), supporting circuitry, and at least a portion of the machine-readable medium integrated in a single chip, or with one or more FPGAs (field programmable gate arrays), PLDs (programmable logic devices), controllers, state machines, gating logic, discrete hardware components, or any other suitable circuitry, or any combination of circuits capable of performing the various functionalities described throughout this disclosure. Those skilled in the art will recognize how to best implement the functionality described with respect to the processing system, depending on the specific application and the overall design constraints imposed on the overall system.

[0085] The machine-readable medium may include several software modules. These software modules include instructions that cause a processing system to perform various functions when executed by a device (such as a processor). These software modules may include a transmission module and a reception module. Each software module may reside in a single storage device or be distributed across multiple storage devices. As an example, when a triggering event occurs, a software module may be loaded into a RAM from a hard drive. During the execution of the software module, the processor may load some instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general register file for execution by the processor. When the functionality of a software module is described below, it will be understood that such functionality is implemented by the processor when the processor executes instructions from the software module.

[0086] If implemented in software, each function can be stored on a computer-readable medium or transmitted therefrom as one or more instructions or codes. Computer-readable media include both computer storage media and communication media, and these media include any media that facilitate the transfer of a computer program from one place to another. Storage media can be any available media that can be accessed by a computer. As an example and not limitation, such computer-readable media may include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, disk storage or other magnetic storage devices, or any other media that can be used to carry or store the desired program code in the form of an instruction or data structure and can be accessed by a computer. Any connection is also properly referred to as a computer-readable medium. For example, if the software is transmitted from a website, a server, or other remote sources using a coaxial cable, a fiber optic cable, a twisted pair, a digital subscriber line (DSL), or a wireless technology (such as infrared (IR), radio, and microwaves), the coaxial cable, the fiber optic cable, the twisted pair, the DSL, or the wireless technology (such as infrared, radio, and microwaves) are included in the definition of the medium. Disk and disc as used herein include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray® disc, wherein disk usually reproduces data magnetically, and disc reproduces data optically with laser. Therefore, in some aspects, computer-readable medium may include non-transient computer-readable medium (e.g., tangible medium). In addition, for other aspects, computer-readable medium may include transient computer-readable medium (e.g., signal). The above combination should also be included in the scope of computer-readable medium.

[0087] Thus, some aspects may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium having stored (and / or encoded) thereon instructions that can be executed by one or more processors to perform the operations described herein. In some aspects, a computer program product may include packaging materials.

[0088] It will be understood that the claims are not limited to the precise configuration and components illustrated above. Various changes, substitutions and variations may be made in the arrangement, operation and details of the methods and apparatus described above without departing from the scope of the claims.
