Description

Technical Field

[0001] The present invention relates to the technical field of humidity regulating equipment, and in particular provides a control method for a humidifier and a humidifier. Background Art

[0002] Existing humidifiers typically use ultrasonic atomizers to atomize water into extremely fine particles, which are then blown into the air by a fan to humidify the space. However, this method cannot quickly humidify the air in the space because the water mist needs to evaporate in the air to truly increase the humidity in the space, and this process is relatively slow. As a result, the humidification efficiency of ultrasonic atomizers is relatively low.

[0003] However, in order to solve the problem of low humidification efficiency of humidifiers using ultrasonic atomizers, it is usually adopted to increase the oscillation frequency of the ultrasonic atomizer or increase the fan blowing intensity of the ultrasonic atomizer and increase the temperature of the liquid water in the atomizer to increase the speed at which water mist is converted into steam, thereby improving the humidification efficiency of the humidifier using ultrasonic atomizers. However, the water mist blown into the air by the humidifier using the above technical means still needs to evaporate before humidifying the air in the space. Therefore, the effect of improving the humidification efficiency of the humidifier using the atomizer by the above technical means is not obvious.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0053] Humidifiers using ultrasonic atomizers in the current prior art have the problem of low humidification efficiency when humidifying space air. To this end, the humidifier of the present invention is provided with a heating and pre-wetting assembly on a chamber connected to the ultrasonic atomizer. Before the ultrasonic atomizer humidifies the space, the heating and pre-wetting assembly heats the interior of the chamber and adds water to the inner wall of the chamber. This allows the humidifier to blow air mixed with evaporated gaseous water and extremely fine particles of liquid water into the air when humidifying the space, thereby accelerating the humidifier's humidification efficiency for the space. Moreover, because the chamber is heated by the heating and pre-wetting assembly, the extremely fine particles blown out from the interior of the chamber can be vaporized into gaseous water at a relatively faster evaporation rate, which can further accelerate the humidification rate of the humidifier for the space air.

[0054] like Figure 1As shown, the humidifier 100 includes a chamber 1, a heating and pre-wetting component 2, and an ultrasonic atomizer 4. The chamber 1 is provided inside a housing 9 of the humidifier 100. The heating and pre-wetting component 2 is arranged inside the shell 9 and connected to the inner wall 11 of the chamber, and is used to transport water mist into the interior of the chamber 1. Furthermore, the ultrasonic atomizer 4 includes a fan 42 and an ultrasonic oscillator 41. The fan 42 includes a first air inlet 421, a second air inlet 422 and an air outlet 423 of the fan. The air outlet 423 of the fan is connected to the inner wall 11 of the chamber. The first air inlet 421 of the fan is connected to the air outlet of the return air channel 3, and the air inlet of the return air channel 3 is connected to the inner wall 11 of the chamber, so that the air inside the chamber 1 circulates between the return air channel 3 and the chamber 1 under the action of the fan 42. The second air inlet 422 of the fan is connected to the outside of the humidifier 100, so that the air outside the humidifier 100 enters the interior of the chamber 1 under the action of the fan 42. In this way, after the ultrasonic oscillator 41 generates water mist, the fan 42 can take in air through the second air inlet 422, and the fan 42 blows the water mist out of the outside of the chamber 1. The ultrasonic oscillator 41 is arranged on the inner wall 11 of the chamber and is connected to the water tank 5 arranged inside the shell 9, and is used to atomize the liquid water in the water tank 5 into extremely fine water mist. The air outlet 423 of the fan is arranged near the ultrasonic oscillator 41, and is used to blow away the water mist atomized by the ultrasonic oscillator 41, so as to speed up the efficiency of the ultrasonic oscillator 41 in converting liquid water into water mist. The heating and pre-wetting assembly 2 is arranged between the shell 9 and the chamber 1, and is used to heat the chamber 1 and add water to the inner wall 11 of the chamber. Furthermore, the heating and pre-wetting assembly 2 includes a steam generator 22 and a heating device 21. The steam generator 22 is arranged between the chamber 1 and the shell 9. The outlet of the steam generator 22 is arranged on the inner wall 11 of the chamber so that the steam generator 22 can discharge the liquid water into the interior of the chamber 1 after vaporizing it. In this way, when the higher temperature steam enters the interior of the chamber 1 and encounters the inner wall 11 of the chamber, it can condense into water droplets and adhere to the inner wall 11 of the chamber, thereby adding water to the inner wall 11 of the chamber. In addition, during the condensation process of the steam, heat is released accordingly, which can also increase the temperature inside the chamber 1, thereby increasing the heating speed of the chamber 1, so as to further improve the humidification efficiency of the humidifier 100. The heating device 21 is arranged at the air outlet 423 of the fan, and is used to heat the air blown out of the air outlet 423 of the fan.

[0055] It should be noted that, although the above-described heating and pre-wetting component 2 adds water to the inner wall 11 of the chamber through the steam generator 22, this is not restrictive. Those skilled in the art can also set the heating and pre-wetting component 2 to include a spray component and a heating device with heating and humidifying functions as needed, so that the heating and pre-wetting component 2 can add water to the inner wall 11 of the chamber through the spray device and can also heat the chamber through the heating device. In addition, a plurality of recesses can be provided on the inner wall 11 of the chamber so that the inner wall 11 of the chamber can retain more water. Obviously, the heating The hot prewetting component 2 can also be configured as other devices with heating and humidifying functions, so that water can be added to the inner wall 11 of the chamber and the interior of the chamber can be heated by the heated prewetting component 2. For example, in other embodiments of the present invention, the heated prewetting component 2 can also include a water absorption structure with honeycomb-like holes arranged on the inner wall 11 of the chamber and a heating device arranged inside the chamber 1, so that liquid water can be added to the water absorption structure through a water pump connected to a water pipe during the prewetting stage, thereby adding water to the inner wall 11 of the chamber and heating the interior of the chamber 1 through the heating device.

[0056] In addition, although the heating and pre-wetting component 2 described above adds water to the inner wall 11 of the chamber through a steam generator 22, a spray device or a water pump, this is not restrictive. Without deviating from the basic principles of the present invention, technical personnel in this field can flexibly select the setting form of the heating and pre-wetting component 2 according to the specific application scenario, as long as the heating and pre-wetting component 2 can preheat the chamber 1 and add water to the inner wall 11 of the chamber.

[0057] In the present application, the chamber 1 is provided with an air outlet channel 8 that can be opened and closed, so that the humidifier 100 can adjust the opening and closing of the air outlet channel 8 according to its own working state. Before the humidifier 100 humidifies the space, the chamber 1 is controlled to be in a closed state so that the heating and pre-wetting component 2 can heat and pre-wet the chamber 1. When the humidifier 100 humidifies the space, the chamber 1 is controlled to be in an open state so that the water mist generated by the ultrasonic atomizer 4 can enter the space to humidify the space.

[0058] In the present application, the humidifier 100 further includes a temperature sensor 6 and a humidity sensor 7. The temperature sensor 6 is provided inside the chamber 1 for detecting the temperature inside the chamber 1. The humidity sensor 7 is provided outside the humidifier 100 for detecting the air humidity in the space.

[0059] It should be noted that although the temperature sensor 6 described above includes a first temperature sensor 62 and a second temperature sensor 61, this is not restrictive. In other embodiments of the present invention, the temperature sensor 6 may also only include a temperature sensor 6 arranged inside the chamber 1. As long as the temperature sensor 6 can detect the indoor temperature when the humidifier 100 is not performing humidification, the temperature detected by the temperature sensor 6 is the internal temperature of the space.

[0060] In the present application, the humidifier 100 also includes a control module (not shown), which is respectively connected to the heating and pre-wetting component 2, the ultrasonic nebulizer 4, the air outlet channel 8 that can be opened and closed, and the temperature sensor 6 and the humidity sensor 7, so that the control module can control the status of the heating and pre-wetting component 2, the ultrasonic nebulizer 4 and the air outlet channel 8 that can be opened and closed according to the received control instructions, temperature information and humidity information, so that the humidifier 100 can humidify the air in the space.

[0061] It should be noted that the control module may be a control chip of the humidifier 100 itself, or a controller specifically used to execute the control method of the present application, or a functional module or functional unit of the controller.

[0062] Refer to the following Figures 2 to 7 To illustrate possible implementations of the humidifier control method of the present invention.

[0063] like Figure 2 As shown, in a possible embodiment, the control method of the humidifier of the present invention includes the following steps:

[0064] S101: receiving a control instruction, the control instruction including setting humidity;

[0065] S102: Obtaining the space temperature, initial space humidity, and space size of the space where the humidifier is located;

[0066] S103: According to the set humidity, space temperature, initial space humidity and space size, determine the first attachment weight of water that needs to be attached to the inner wall of the chamber when the chamber is in a sealed state, and determine the humidification temperature required by the chamber and the atomization power of the ultrasonic nebulizer when the chamber is in an open state.

[0067] In S101, the control instruction can be input by the user through a control button (not shown) set on the humidifier, but this is not restrictive. In the specific implementation of the present invention, the control instruction can also be input through a mobile terminal, where the control instruction includes setting the humidity.

[0068] In S102, the room temperature is obtained by a second temperature sensor. The initial room humidity is obtained by a humidity sensor. The room dimensions can be input by a user via a control button provided on the humidifier. Obviously, the room dimensions can also be input by a user via a mobile terminal. It should be noted that the room dimensions can also be obtained by a distance sensor provided on the humidifier.

[0069] In S103, the first attachment weight of water that needs to be attached to the inner wall of the chamber when in a sealed state is determined based on the user's set humidity, the space temperature, the initial space humidity, and the space size, as well as the required humidification temperature of the chamber and the atomization power of the ultrasonic atomizer when in an open state are determined, so that when the user humidifies the space through the humidifier, the temperature inside the chamber is at the humidification temperature, and the ultrasonic atomizer can atomize liquid water at the atomization power. In this way, since the temperature inside the chamber is at the humidification temperature, the liquid water attached to the inner wall of the chamber can have a faster vaporization speed, so that the liquid water attached to the inner wall of the chamber can be converted into gaseous water, so that the gaseous water can be blown into the space along with the water mist, thereby improving the humidification efficiency of the humidifier for the space.

[0070] It should be noted that when the humidifier humidifies the space through the ultrasonic atomizer, the temperature inside the chamber can always be at the humidification temperature. In this way, the water mist can also have a higher temperature when it flows through the chamber into the space. In this way, the vaporization speed of the water mist entering the space is accelerated, thereby further improving the humidification efficiency of the humidifier.

[0071] In addition, the humidification temperature can be set according to specific needs so as to reduce the speed at which the water mist inside the chamber forms liquid water on the inner wall of the chamber when it encounters the inner wall of the chamber, and to increase the vaporization speed of the water attached to the inner wall of the chamber. In this way, when the humidifier humidifies the space through the ultrasonic atomizer, it can reduce the speed at which liquid water forms on the inner wall of the chamber, and increase the vaporization speed of the liquid water on the inner wall of the chamber.

[0072] Furthermore, since the humidification temperature is determined based on the space temperature, when the humidifier humidifies the space, the humidification temperature of the chamber can be considered based on the temperature of the space, so that when the humidifier humidifies the space, it can humidify the space as much as possible while reducing the impact on the indoor temperature, thereby improving user satisfaction.

[0073] Finally, in other embodiments of the present invention, the humidifier can also have multiple humidification modes, for example, including a fast humidification mode and a standard humidification mode. Specifically, when in the fast humidification mode, the interior of the chamber can have a higher humidification temperature and the fan can have a higher speed. In this way, when the humidifier humidifies the space, the ultrasonic atomizer can also have a higher atomization power, which can enable the humidifier to have a higher humidification efficiency for the space. The standard humidification mode can make the humidification temperature inside the chamber closer to the temperature of the space, which can enable the humidifier to reduce the impact on the temperature of the space when humidifying the space.

[0074] like Figure 3 As shown, in a possible embodiment, the control method of the humidifier of the present invention further includes the following steps:

[0075] S201: calling a preset first mapping relationship table storing correspondences between set humidity, space temperature, initial space humidity, and space size, and first attachment weight of water, humidification temperature, and atomization power;

[0076] S202: Determine a first attachment weight of water, a humidification temperature, and an atomization power according to the set humidity, the space temperature, the initial space humidity, the space size, and a first mapping relationship table.

[0077] In S201, a first mapping relationship table is stored in the memory, which stores a correspondence between the set humidity, space temperature, initial space humidity, and space dimensions, and the first water attachment weight, humidification temperature, and atomization power. It should be noted that the correspondence between the set humidity, space temperature, initial space humidity, and space dimensions, and the first water attachment weight, humidification temperature, and atomization power in the first mapping relationship table can be obtained through experiments. This allows the humidifier to accelerate the evaporation rate of water attached to the inner wall of the chamber while reducing the condensation rate of water mist on the inner wall of the chamber during humidification of the space by the humidifier, as the interior of the chamber is always at the humidification temperature. This allows the water attached to the inner wall of the chamber to gradually evaporate into gaseous water, thereby accelerating the humidification efficiency of the humidifier in the space.

[0078] like Figure 4 As shown, in a possible embodiment, the control method of the humidifier of the present invention includes the following steps:

[0079] S301: calling a preset second mapping relationship table storing correspondences between set humidity, space temperature, initial space humidity, and space size, and first attachment weight of water, humidification temperature, fan power, and ultrasonic oscillator power;

[0080] S302: Determine a first attachment weight of water, a humidification temperature, a fan power, and an ultrasonic oscillator power according to the set humidity, the space temperature, the initial space humidity, the space size, and a second mapping relationship table.

[0081] In S301, a preset second mapping relationship table storing set humidity, space temperature, initial space humidity and space size, and first attachment weight, humidification temperature, fan power and ultrasonic oscillator power is stored in the memory. It should be noted that the correspondence between the set humidity, space temperature, initial space humidity and space size and the first attachment weight, humidification temperature, fan power and ultrasonic oscillator power in the second mapping table can be obtained through experiments, so that in the process of humidifying the space through the humidifier, the humidifier can determine the first attachment weight, humidification humidity, fan power and ultrasonic oscillator power of the water on the inner wall of the chamber according to the set humidity, space temperature, initial space humidity and space size, so that the water attached to the inner wall of the chamber has a faster evaporation rate under the higher humidification temperature inside the chamber and the action of the fan blowing, so that the water attached to the inner wall of the chamber can be completely evaporated or a preset residual amount of water is attached to the inner wall in a humidification working cycle from the start to the end of humidification of the humidifier, so that liquid water is always attached to the inner wall of the chamber in a humidification working cycle. In this way, the liquid water attached to the inner wall of the chamber can always be in an evaporating state when the humidifier is in humidification operation, thereby accelerating the humidification efficiency of the humidifier for the space.

[0082] like Figure 5 As shown, in a possible embodiment, the control method of the humidifier of the present invention includes the following steps:

[0083] S401: calling a preset third mapping relationship table storing a correspondence between a first attachment weight of water and an operating time of a heating and pre-wetting component;

[0084] S402: Determining the operating time of the heating and pre-wetting component according to the first attachment weight of water and the third mapping relationship table;

[0085] In S401, a third mapping table is stored in the memory, which stores a correspondence between the first weight of water adhered and the operating time of the heating and pre-wetting assembly. It should be noted that the correspondence between the first weight of water adhered and the operating time of the heating and pre-wetting assembly in the third mapping table can be obtained through experiments, so that when water is added to the inner wall of the chamber by the heating and pre-wetting assembly, the amount of water added to the inner wall of the chamber can be controlled by controlling the operating time of the heating and pre-wetting assembly.

[0086] It should be noted that, in the present invention, the heating and pre-wetting component includes a steam generator, which is configured to heat and vaporize liquid water into high-temperature water vapor through the steam generator before the humidifier performs humidification work on the space, so that the water vapor contacts the inner wall of the chamber, thereby condensing into liquid water and adhering to the inner wall of the chamber, thereby adding water to the inner wall of the chamber. In addition, although the heating and pre-wetting component described above is a steam generator, this is not restrictive. In the specific implementation of the present invention, the heating and pre-wetting component can also be a spraying device, which is configured to spray liquid water onto the inner wall of the chamber so that liquid water is attached to the inner wall of the chamber. In addition, in the specific implementation of the present invention, in order to make it easier for liquid water to adhere to the inner wall of the chamber, evenly distributed depressions can also be provided on the inner wall of the chamber so that the liquid water attached to the inner wall of the chamber can be more easily retained in the depressions.

[0087] like Figure 6 As shown, in one possible embodiment, the humidifier further includes a weight sensor, which is provided between the inner wall of the chamber and the housing of the humidifier and is used to detect changes in the weight of the chamber. The control method of the humidifier of the present invention includes the following steps:

[0088] S501: Acquire a first current weight of the chamber in a closed state;

[0089] S502: If the first current weight of the chamber is less than the sum of the initial weight of the chamber and the first attached weight of the water, controlling the heating and pre-wetting component to continue operating;

[0090] S503: If the first current weight of the chamber is greater than or equal to the sum of the initial weight of the chamber and the first attached weight of the water, the heating and pre-wetting component is controlled to stop operating.

[0091] In S501 , a first current weight of the chamber in a closed state is acquired through a weight sensor.

[0092] In S502, if the first current weight of the chamber is less than the sum of the initial weight of the chamber and the first attached weight of the water, the heating and pre-wetting component is controlled to continue running so that the humidifier can control the heating and pre-wetting component to continue adding water to the inner wall of the chamber.

[0093] In S502, if the first current weight of the chamber is greater than or equal to the sum of the initial weight of the chamber and the first attached weight of the water, the heating and pre-wetting component is controlled to stop running so that the humidifier can control the heating and pre-wetting component to stop adding water to the inner wall of the chamber, so that water of the first attached weight is attached to the inner wall of the chamber.

[0094] like Figure 7 As shown, in a possible embodiment, the control method of the humidifier of the present invention further includes the following steps:

[0095] S601: Acquire a second current weight of the chamber in the open state;

[0096] S602: Obtain the current humidity of the space;

[0097] S603: Controlling the operation of the humidifier according to the comparison result between the second current weight and the initial weight of the chamber and the current humidity and the set humidity.

[0098] In S601, the second current weight of the chamber in the open state is obtained through the weight sensor, so that the humidifier can obtain the change in the weight of the chamber when it is in humidification operation through the weight sensor, thereby being able to monitor the weight of water attached to the inner wall of the chamber.

[0099] In S602, the current humidity of the space is obtained through the humidity sensor so that the humidifier can monitor the humidity of the space.

[0100] In S603 , the operation of the humidifier is controlled according to the comparison structure between the second current weight and the initial weight of the chamber and the current humidity and the set humidity.

[0101] like Figure 7 As shown, in a possible implementation manner, the above step S603 further includes the following steps:

[0102] S701: If the second current weight is equal to the initial weight of the chamber and the current humidity is greater than or equal to the set humidity, the humidifier is controlled to stop running.

[0103] In S701, if the second current weight is equal to the initial weight of the chamber and the current humidity is greater than or equal to the set humidity, it indicates that the humidifier has completed humidifying the space and the weight of water attached to the inner wall of the chamber is zero, and the humidifier is controlled to stop running.

[0104] like Figure 7 As shown, in a possible implementation manner, the above step S603 further includes the following steps:

[0105] S801: If the second current weight is equal to the initial weight of the chamber and the current humidity is less than the set humidity, the chamber is controlled to switch from an open state to a closed state, and the heating and pre-wetting component is controlled to add water with a second attachment weight to the inner wall of the chamber;

[0106] S802: When the weight of water attached to the inner wall of the chamber reaches a second attachment weight, the chamber is controlled to switch from a closed state to an open state, and the ultrasonic atomizer is continued to be controlled to operate at an atomizing power, and the heating pre-wetting component is controlled to keep the temperature of the chamber at a humidification temperature.

[0107] In S801, if the second current weight is equal to the initial weight of the chamber and the current humidity is less than the set humidity, it means that the water attached to the inner wall of the chamber has evaporated before the humidity of the space reaches the set humidity. At this time, the chamber is controlled to switch from an open state to a closed state, and the heating and pre-wetting component is controlled to add water with a weight of the second attachment weight to the inner wall of the chamber, so that the humidifier can always maintain liquid water attached to the inner wall of the chamber when humidifying the air inside the space.

[0108] In S802, when the weight of water attached to the inner wall of the chamber reaches the second attachment weight, the chamber is controlled to switch from a closed state to an open state, and the ultrasonic nebulizer is continued to be controlled to operate at the atomizing power, and the heating pre-wetting component is controlled to keep the temperature of the chamber at the humidification temperature. In this way, when the humidifier humidifies the space through the ultrasonic nebulizer, the temperature inside the chamber can still be at a higher temperature, so that the water on the inner wall of the chamber can always be at a higher evaporation rate, so that even if the ultrasonic nebulizer continues to transport water mist into the interior of the chamber and forms attached liquid water on the inner wall of the chamber, the weight of the liquid water attached to the inner wall of the chamber can be gradually reduced, thereby making the humidifier have a higher humidification efficiency.

[0109] like Figure 7 As shown, in a possible implementation manner, the above step S603 further includes the following steps:

[0110] S901: If the second current weight is greater than the initial weight of the chamber and the current humidity is greater than or equal to the set humidity, control the ultrasonic atomizer to stop humidification;

[0111] S902: Control the heating and pre-wetting component to heat the chamber until the second current weight of the chamber is equal to the initial weight of the chamber.

[0112] In S901, if the second current weight of the inner wall of the chamber of the humidifier in the humidifying state is greater than the initial weight of the chamber and the current humidity of the space is greater than or equal to the set humidity, it means that the humidifier has completed humidifying the space. At this time, the ultrasonic atomizer is controlled to stop humidifying the space.

[0113] In S902, after the space humidity reaches the set humidity, if there is still liquid water attached to the inner wall of the chamber, the heating pre-wetting component is controlled to heat the chamber until the second current weight of the chamber is equal to the initial weight of the chamber, so that the liquid water on the inner wall of the chamber can be completely evaporated, reducing the risk of bacteria breeding due to liquid water still attached to the inner wall of the chamber after the humidifier completes humidification.
