Description

Technical Field

[0001] The invention relates to the field of humidifiers, in particular to a humidifier with detection and monitoring function and a detection and monitoring method for the humidifier. Background Art

[0002] Air humidity is one of the important factors that affect environmental comfort, especially in northern regions and places where air conditioning is often used. Therefore, humidifiers that increase environmental humidity are becoming an essential small appliance for many families. Humidifiers usually use a fan to inhale air, and then let the air with the generated water mist blow out to the surrounding environment to humidify the air. One type of humidifier currently available is an evaporative humidifier, which increases the humidity of the air by evaporating liquid water. It does not require an ultrasonic atomizer and has the advantages of low cost, simple structure and not easy to damage.

[0003] An existing type of evaporative humidifier uses heating to increase the evaporation rate, which is often achieved by heating the water in the entire water tank or heating the air. However, this method is slow to heat and requires high heating power. In particular, the method of heating the water in the water tank is prone to scale formation on the surface of the heating element after long-term use, affecting the heat transfer between the heating element and the water in the water tank. If it is not cleaned in time, the power consumption of the humidifier will increase and the humidification efficiency will be reduced. Summary of the invention

[0004] The purpose of the present invention is to address the problems existing in the above-mentioned background technology and to provide a humidifier with detection and monitoring and a detection and monitoring method for the humidifier. By automatically monitoring the temperature and water volume of the heating disk, it ensures that the amount of water evaporated by the heating disk each time is appropriate, and can also prevent scale accumulation after the heating disk has been running for a long time, thereby ensuring the efficient evaporation and humidification effect of the humidifier from two aspects.

[0005] In order to achieve the above object, the technical solutions of the present invention are:

[0006] A humidifier with detection and monitoring includes a water tank, an atomizing assembly and a water pump. The water pump transports water in the water tank to the atomizing assembly for atomization. A temperature sensor, a flow meter and a controller are also provided.

[0007] The atomizing assembly includes a heating element, which is used to heat water delivered thereto by a water pump to generate water vapor;

[0008] The temperature sensor is used to detect the temperature data of the heating element and send the real-time temperature data to the controller;

[0009] The flow meter is used to detect the accumulated water flow data delivered by the water pump to the heating element, and send the accumulated water flow data to the controller;

[0010] The controller is used to receive the temperature data and water flow data and determine the difference between the two and the preset value. When the temperature data is greater than the preset value, the water pump is controlled to start replenishing water for the heating element, otherwise the water pump is controlled to stop working; when the accumulated water flow data is greater than the preset value, the controller issues a scale cleaning alarm message.

[0011] In the prior art, when heating is used to improve humidification efficiency, the efficiency is low and it does not take into account that the scale on the heating element after heating water for a long time will affect the subsequent heating use. In this solution, the heating element is not directly placed in the water tank to heat all the water, but only heats the water delivered by the water pump. The amount of water heated each time is less. When the temperature of the heating element is high enough, the water on the heating element can be instantly evaporated to form steam, and the humidification efficiency is high.

[0012] Correspondingly, because the amount of water transported by the water pump is small, the heating element can evaporate it quickly. In order to prevent the heating element from overheating and causing overheating inside the humidifier, thereby causing damage to other components or safety accidents, this solution uses a temperature sensor to detect the real-time temperature of the heating element. When the temperature of the heating element is higher than the preset value, it can be judged that the amount of water on it is too little or has evaporated, and the controller will control the water pump to replenish water to the heating element; when the temperature of the heating element is lower than the preset value, it can be judged that the amount of water on it is sufficient and it is still continuing to evaporate and take away heat, so there is no need for a water pump to replenish water. This method of automatic water replenishment through temperature control is not only safer, but also can keep the amount of water on the heating element always within a certain range, so the efficiency of evaporating water can also always be maintained within a certain range, ensuring stable and efficient steam output.

[0013] In combination with this, the present invention also monitors the cumulative water flow delivered by the water pump to the heating element, and uses the comparison of the cumulative water flow with a preset value as a standard for determining whether scale has formed on the heating element. Although the water quality in different areas varies, the actual scaling of the heating element is difficult to detect automatically. This method takes into account the frequency of use by users and can more realistically reflect the severity of scaling of the heating element. It is a monitoring solution that is easy to implement and can clean scale on the heating element more promptly, thereby ensuring the thermal conductivity between the heating element and water, and thereby ensuring efficient steam output.

[0014] Furthermore, the heating element is disc-shaped, the upper part of the heating element receives water from the water pump, and the lower part of the heating element is in close contact with the temperature sensor; the flow meter is arranged on the water flow channel between the water pump and the atomizing assembly.

[0015] Further, when the controller receives feedback information of closing the scale cleaning alarm, the flow meter is controlled to clear the accumulated water flow data. Each time the feedback information of closing the scale cleaning alarm is received, it is assumed that the scale has been cleaned after the scale cleaning alarm information is issued, so the water flow is re-recorded.

[0016] Furthermore, the scale cleaning alarm information is issued by lighting up the indicator light; or by making a sound; and also includes a reminder stop switch, the reminder stop switch is used to issue a scale cleaning shutdown alarm message, and when the controller receives feedback information of closing the scale cleaning alarm, it controls the flow meter to clear the accumulated water flow data. There are many ways to issue a reminder, and in the present invention, it is preferred to light up a light and make a sound. This is because considering that many humidifiers do not have a screen, these two methods do not rely on the screen and are relatively low in cost; and the lighting of the indicator light can be clearly seen by the user, and the sound can also be easily heard, which can achieve a good reminder effect. Since the reminder stop switch needs to be triggered by external force, when this switch is triggered, it means that the user should have known that the scale needs to be cleaned, and the data can be cleared to start recording the water flow again.

[0017] Furthermore, a communication module is included. When the flow meter reaches a preset value, the controller sends a scale cleaning alarm message to the client through the communication module. The client can be a user's mobile smart terminal with a corresponding control app installed. In this way, the user can conveniently remotely control the humidifier, making the humidifier more intelligent and convenient.

[0018] Furthermore, it also includes a base arranged below the water tank, wherein the atomizing assembly, water pump, temperature sensor, flow meter and controller are arranged in the base; the atomizing assembly is arranged in the middle of the base, and the water pump and flow meter are arranged on the side of the atomizing assembly, and the water outlet of the water tank, the water pump, the flow meter and the atomizing assembly are sequentially connected through water pipes. The base provides an installation position for the main components except the water tank, and is arranged above and below the water tank. The water at the bottom of the water tank can also be completely transported to the water pump through the water outlet structure and then transported to the atomizing assembly. The water pump and flow meter are arranged on the side of the atomizing assembly to save space.

[0019] Furthermore, the temperature data has a range of above 100°C, and the preset value of the water flow data has a range of 25L-54L. According to experiments conducted by the inventor, the heating element can ensure a good heating and evaporation effect within this preset value, and scale will not accumulate in large quantities when using water of normal hardness.

[0020] The present invention also provides a detection and monitoring method for the humidifier, comprising the following steps:

[0021] Temperature control water replenishment: Real-time detection of the temperature of the heating element, judging whether the temperature is greater than a preset value, and when the judgment result is yes, starting to replenish water to the heating element; when the judgment result is no, stopping replenishing water to the heating element;

[0022] Flow monitoring alarm: detect the cumulative water flow obtained by the heating element, and determine whether the cumulative water flow is greater than a preset value. When the judgment result is yes, a scale cleaning alarm message is issued.

[0023] As mentioned above, the temperature-controlled water replenishment method can not only keep the amount of water on the heating element within a certain range to stably maintain a good heating evaporation level, but also avoid overheating of the heating element and causing safety hazards. The flow monitoring alarm can remind consumers to clean the scale on the heating element in time to prevent the scale on the heating element from affecting the heat transfer of the heating element to the water, thereby affecting the evaporation of water. The method combining the temperature-controlled water replenishment step and the flow monitoring alarm step allows the heating evaporative humidifier to maintain a stable and high level of humidification effect for a long time.

[0024] Furthermore, the temperature-controlled water replenishment step includes: the temperature sensor detects the temperature of the heating element in real time, the controller determines whether the temperature is greater than a preset value, when the judgment result is yes, the controller sends an open command to the water pump, and the water pump starts to replenish water to the heating element after receiving the open command; when the judgment result is no and the water pump is in the open state, the controller sends a stop command to the water pump, and the water pump stops replenishing water after receiving the stop command; when the judgment result is no and the water pump is in an inoperative state, the water pump remains in an inoperative state. In the specific judgment step, since the detected temperature is a real-time temperature, when the temperature of the heating element is lower than the preset value, the heating element may be in two states, one of which is a state of changing from a high temperature state to a low temperature state, at which time the water pump is in an open state, and the controller needs to turn off the water pump to stop replenishing water; the other is a state of being in a low temperature state for a period of time, at which time the water pump is in an off state, then the water pump can be kept in an off state without replenishing water.

[0025] Furthermore, the preset value of the cumulative water flow is an adjustable value. Since the scaling speed of the heating element is closely related to the water quality of the water it heats, the scaling speed of the heating element may be different for users in different regions. The adjustable preset value of the cumulative water flow is convenient for users to adjust it according to the hardness of the water used in the application, which is more flexible and close to real life.

[0033] A humidifier with detection and monitoring function and a detection and monitoring method for the humidifier of the present invention are described in detail in conjunction with the accompanying drawings to explain and illustrate the protection scope of the present invention.

[0034] A humidifier with detection and monitoring, comprising a water tank 1, an atomizing assembly and a water pump 2, wherein the water pump 2 transports water in the water tank 1 to the atomizing assembly for atomization, and is also provided with a temperature sensor 3, a flow meter 4 and a controller 5.

[0035] The atomizing assembly includes a heating element 6, which is used to heat water delivered thereto by the water pump 2 to generate water vapor;

[0036] The temperature sensor 3 is used to detect the temperature data of the heating element 6 and send the real-time temperature data to the controller 5;

[0037] The flow meter 4 is used to detect the accumulated water flow data delivered by the water pump 2 to the heating element 6, and send the accumulated water flow data to the controller 5;

[0038] The controller 5 is used to receive the temperature data and water flow data and determine the difference between the two and the preset value. When the temperature data is greater than the preset value, the water pump 2 is controlled to start replenishing water for the heating element 6, otherwise the water pump 2 is controlled to stop working; when the accumulated water flow data is greater than the preset value, the controller issues a scale cleaning alarm message. The controller 5 is preferably a PCB control board.

[0039] This solution adopts a solution different from the heating evaporation humidifier in the prior art. In this solution, the heating element 6 is not directly set in the water tank 1 to heat all the water, but only heats the water delivered by the water pump 2. The amount of water heated each time is less. When the temperature of the heating element 6 is high enough, the water on the heating element 6 can be instantly evaporated to form steam, and the humidification efficiency is high. Correspondingly, because the amount of water delivered by the water pump 2 is small, the heating element 6 can evaporate it quickly. In order to ensure that the heating element 6 overheats and causes the internal overheating of the humidifier to cause damage to other components or safety accidents, this solution uses a temperature sensor 3 to detect the real-time temperature of the heating element 6. When the temperature of the heating element 6 is higher than the preset value, it can be judged that the amount of water on it is too little or has been evaporated, and the controller 5 will control the water pump 2 to replenish the heating element 6; when the temperature of the heating element 6 is lower than the preset value, it can be judged that the amount of water on it is sufficient and it is still continuing to evaporate and take away heat, so there is no need for the water pump 2 to replenish water. This automatic water replenishment method through temperature control is not only safer, but also can keep the amount of water on the heating element 6 within a certain range, so the efficiency of evaporating water can also be kept within a certain range, ensuring stable and efficient steam output. In combination with this, the present invention also monitors the cumulative water flow delivered by the water pump 2 to the heating element 6, and compares the cumulative water flow with the preset value as a standard for judging whether scale has formed on the heating element 6. Although the water quality in different regions varies, the actual scaling of the heating element 6 is difficult to detect automatically. This method takes into account the user's frequency of use and can more realistically reflect the severity of scaling of the heating element 6. It is a monitoring solution that is easy to implement, and can clean the scale on the heating element 6 in a more timely manner, ensuring the heat transfer efficiency between the heating element 6 and water, thereby ensuring efficient steam output.

[0040] like Figures 1 to 4 As shown, as a preferred embodiment of the specific structure, the heating element 6 is disc-shaped, the upper part of the heating element 6 receives water from the water pump 2, and the lower part of the heating element 6 is close to the temperature sensor; the flow meter 4 is arranged on the water flow channel between the water pump 2 and the atomizing assembly. It also includes a base 8 arranged below the water tank 1, and the atomizing assembly, the water pump 2, the temperature sensor 3, the flow meter 4 and the controller 5 are arranged in the base 8; the atomizing assembly is arranged in the middle of the base 8, and the water pump 2 and the flow meter 4 are arranged on the side of the atomizing assembly, and the water outlet of the water tank 1, the water pump 2, the flow meter 4 and the atomizing assembly are connected in sequence through water pipes. The base 8 provides an installation position for the main components except the water tank 1, and is arranged up and down with the water tank 1. The water at the bottom of the water tank 1 can also be completely transported to the water pump 2 through the water structure 11 and then transported to the atomizing assembly. The water pump 2 and the flow meter 4 are arranged on the side of the atomizing assembly to save space.

[0041] It also includes a water adding structure 61, which is arranged above the heating element 6, including a drainage channel 611 and a diffuser structure. The drainage channel 611 receives water from the water tank 1 through a water outlet 612 and diverts the water to the diffuser structure. The diffuser structure disperses the water and flows it into the heating element 6 below. The water atomized by the atomizing assembly enters the outside through the mist outlet pipe 62 and the fan. In the case of reducing the amount of heated water, the heating element 6 is not directly immersed in water, but a small amount of water is dispersed by the diffuser structure and then falls on the heating element 6 to be heated in batches; for the heating element 6, more parts can be used to heat water better and the amount of water required to be heated in each part is less than that of the prior art, so the speed at which the water is heated and evaporated can be further improved, and the humidification efficiency is higher, and a better humidification efficiency can be achieved in the heating evaporative humidifier. The diffuser structure includes a concave plate 613 and a water leakage groove 614. The concave plate 613 is used to receive water from the drainage channel 611. The water leakage groove 614 is arranged around the concave plate 613 and receives the water overflowing from the concave plate 613. A plurality of water leakage holes 615 are arranged at the bottom of the water leakage groove 614. The heating element is arranged below the water leakage holes 615. The diffuser structure adopts the concave plate 613 and the water leakage groove 614 arranged in an annular manner. The water first flows into the concave plate 613 under the guidance of the drainage channel 611. When the water in the concave plate 613 is full, it overflows from the edge of the concave plate 613 in all directions. The water leakage groove 614 arranged in an annular manner outside the concave plate 613 can immediately receive the water overflowing from the concave plate 613 at all places, and then divide the water into multiple small streams through the water leakage holes 615 and quickly flow to the heating element. This water adding structure ensures that a large stream of water from the water tank can be quickly divided into multiple small streams, and the water flow dispersion effect is good, and the scattered water can be heated and evaporated more quickly. However, this structure also makes it more prone to dry burning and water scaling problems. Therefore, it is particularly suitable for the automatic monitoring of water replenishment and flow monitoring and automatic reminder of scale cleaning solutions in the present invention.

[0042] Since the flow meter 4 needs to be reset after each scale cleaning, this embodiment provides the following judgment bases for resetting the flow meter 4.

[0043] The first is: when the controller receives feedback information of closing the scale cleaning alarm, the flow meter is controlled to clear the accumulated water flow data. Each time the feedback information of closing the scale cleaning alarm is received, it is assumed that the scale has been cleaned after the scale cleaning alarm information is issued, so the water flow is recorded again.

[0044] The second type is: it also includes a reminder stop switch, the reminder stop switch is used to issue a scale cleaning shutdown alarm message, and when the controller receives feedback information of the scale cleaning shutdown alarm, it controls the flow meter to clear the accumulated water flow data. Since the reminder stop switch needs to be triggered by external force, when this switch is triggered, it means that the user should have known that the scale cleaning is needed, and can restart recording the water flow.

[0045] The third type is: it also includes a communication module, and when the flow meter measurement reaches a preset value, the controller sends a scale cleaning alarm message to the client through the communication module. When the controller receives the feedback information of the client turning off the scale cleaning alarm, the flow meter is controlled to clear the accumulated water flow data. The client can be a mobile smart terminal of the user installed with a corresponding control app. In this way, the user can conveniently remotely control the humidifier, making the humidifier more intelligent and convenient. Specifically, the communication module is preferably a wifi module, and the client is preferably a mobile phone with an app installed. When the flow meter measurement reaches a preset value, the controller sends the scale cleaning alarm message to the mobile phone app through the wifi module via the router to remind the user to clean the scale; after cleaning the scale, by turning off the scale cleaning alarm message on the mobile phone app, the controller controls the flow meter to clear the accumulated water flow data according to the feedback information of the mobile phone app turning off the scale cleaning alarm received by the wifi module.

[0046] On the basis of the above two solutions, a water tank 1 disassembly detection device can be set in the humidifier to detect whether the water tank 1 has been disassembled after the scale cleaning reminder is issued. If it has been disassembled, it is considered that the scale has been cleaned and the accumulated water flow data can be cleared. The water tank 1 disassembly detection device can be a micro switch or a photoelectric sensor, etc., and when it is disassembled, the switch state changes, it is judged to be disassembled.

[0047] This embodiment also provides two preferred solutions for issuing scale cleaning alarm information: issuing the scale cleaning alarm information by lighting a light; or issuing the scale cleaning alarm information by emitting a sound. There are many ways to issue a reminder, and the present invention preferably uses lighting a light and emitting a sound. This is because considering that many humidifiers do not have a screen, these two methods do not rely on a screen and are relatively low in cost; and the lighting of the indicator light can be clearly seen by the user, and the sound can also be easily heard, which can achieve a good reminder effect.

[0048] In setting the preset value, the preferred preset value of the temperature data in this embodiment is 100°C, and the preset value of the temperature data is adjustable, so that the desired humidification effect can be adjusted automatically. The higher the temperature, the greater the humidification amount. The preset value of the water flow data is 25L-54L. According to experiments conducted by the inventor, within this preset value, the heating element 6 can ensure a good heating and evaporation effect, and scale will not accumulate in large quantities when using water of normal hardness.

[0049] The present invention also provides a detection and monitoring method for the humidifier, comprising the following steps:

[0050] like Figure 5 The temperature control and water replenishment steps shown are as follows: real-time detection of the temperature of the heating element 6, judging whether the temperature is greater than a preset value, and when the judgment result is yes, starting to replenish water to the heating element 6; when the judgment result is no, stopping replenishing water to the heating element 6;

[0051] like Figure 6 The flow monitoring and alarm steps shown are: detecting the cumulative water flow obtained by the heating element 6, judging whether the cumulative water flow is greater than a preset value, and when the judgment result is yes, issuing a scale cleaning alarm message.

[0052] As described above, the temperature-controlled water replenishment method can not only keep the amount of water on the heating element 6 within a certain range to stably maintain a good heating evaporation level, but also prevent the heating element 6 from overheating and causing safety hazards. The flow monitoring alarm can remind consumers to clean the scale on the heating element 6 in time to prevent the scale on the heating element 6 from affecting the heat transfer of the heating element 6 to the water, thereby affecting the evaporation of water. The method combining the temperature-controlled water replenishment step and the flow monitoring alarm step allows the heating evaporative humidifier to maintain a stable and high level of humidification effect for a long time.

[0053] like Figure 7As shown, as a preferred solution of the temperature control water replenishment step, it includes: the temperature sensor 3 detects the temperature of the heating element 6 in real time, the controller 5 determines whether the temperature is greater than the preset value, when the judgment result is yes, the controller 5 sends an opening command to the water pump 2, and the water pump 2 starts to replenish water to the heating element 6 after receiving the opening command; when the judgment result is no and the water pump 2 is in the open state, the controller 5 sends a stop command to the water pump 2, and the water pump 2 stops replenishing water after receiving the stop command; when the judgment result is no and the water pump 2 is in the non-working state, the water pump 2 remains in the non-working state. In the specific judgment step, since the detected temperature is the real-time temperature, when the temperature of the heating element 6 is lower than the preset value, the heating element 6 may be in two states, one state is from a high temperature state to a low temperature state, at this time the water pump 2 is in the open state, and the controller 5 needs to turn off the water pump 2 to stop replenishing water; the other is that it has been in a low temperature state for a period of time, at this time the water pump 2 is in the closed state, then the water pump 2 can be kept in the closed state, and no water replenishment is required.

[0054] In order to further optimize the flow monitoring and alarm method, the preset value of the cumulative water flow is an adjustable value. Because the scaling speed of the heating element 6 is closely related to the water hardness of the water it heats, and the water hardness in different regions may be different, the adjustable preset value of the cumulative water flow is convenient for the user to adjust it according to the hardness of the water used in the use occasion, and the use is more flexible and close to the actual life. For example, the tap water in the south has a lower water hardness, and the preset value of the cumulative water flow can be about 50L; the tap water in the north has a higher water hardness, and the preset value of the cumulative water flow can be about 25L.

[0055] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
