Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment, in particular to a sewage discharge control method, a water circulation system and a humidifying device. BACKGROUND

[0002] Humidifiers are generally divided into ordinary humidifiers and evaporative humidifiers. Compared with ordinary humidifiers, evaporative humidifiers have larger humidification capacity and more uniform humidification effect, and therefore are recognized by the majority of users. Evaporative humidifiers utilize the principle of water evaporation and heat absorption, supply water to a liquid distributor through a water tank, the liquid distributor sprays water onto a wet curtain, and when natural wind or internal wind passes through the wet curtain, the water in the wet curtain evaporates and takes away a large amount of latent heat in the air, thereby achieving the purpose of cooling and humidifying the indoor space.

[0003] In the water circulation system of the existing humidifier, a water tank is usually provided for water storage and circulation. The water stored in the water tank is supplied to the wet curtain through pipelines, liquid distributors and other structures. When the water absorption capacity of the wet curtain is saturated, the excess water flows back to the water tank, forming a water circulation. However, the water is easy to carry bacteria, dust and other impurities after passing through the wet curtain and contacting the air. After long-term use, the water quality cleanliness in the water tank will deteriorate. The water attached to the wet curtain will cause the wet curtain to mildew and smell, affecting the normal use of the system and the health of the user.

[0004] Therefore, some existing humidifiers are provided with a filter device to filter impurities in the water. However, the impurities on the filter device are difficult to clean thoroughly after long-term accumulation, which not only is complicated to operate, but also still has the problem of affecting the normal use of the system and the health of the user due to poor water quality cleanliness in the water tank. SUMMARY

[0050] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0051] In order to solve the problem that the humidifier water tank water quality deteriorates, and the wet curtain mildews and smells, a humidifier with two water tanks appears on the market. The first water tank is used to supply water to the wet curtain, and the wet curtain backflow water enters the second water tank. When the water level of the second water tank reaches the high water level, the water supply pipeline of the first water tank is closed, and the second water tank is used to supply water to the wet curtain. When the water in the second water tank is insufficient, the first water tank is used to supply water to the wet curtain. Although the humidifier, the wet curtain backflow water with impurities and bacteria does not enter the first water tank and does not pollute the water in the first water tank, but the water with impurities and bacteria still directly supplies the wet curtain after entering the second water tank. Long-term use still causes the wet curtain to mildew and smell, affects the normal use of the system, and affects the health of the user.

[0052] Based on this, the present application provides a sewage discharge control method, a water circulation system and a humidifying device.

[0053] The embodiments of the sewage discharge control method, the water circulation system and the humidifying device of the present application will be described below in combination with Figs. 1-3

[0054] According to the embodiments of the present application, a water circulation system is provided, which applies the sewage discharge control method. The water circulation system comprises a first water tank 1, a second water tank 2, a switch control piece 3, a water quality detection piece and a control unit. The first water tank 1 is used to store water, and the second water tank 2 is used to store the water discharged from the first water tank 1. The switch control piece 3 is arranged between the first water tank 1 and the second water tank 2. When the water quality clean index in the first water tank 1 does not meet the requirement, the switch control piece 3 is opened, and the water in the first water tank 1 is discharged to the second water tank 2 through the switch control piece 3. The water quality detection piece is arranged in the first water tank 1 and is used to detect the water quality clean index of the water in the first water tank 1. The signal input end of the control unit is electrically connected with the water quality detection piece, and the signal output end of the control unit is electrically connected with the switch control piece 3.

[0055] ​The water circulation system adopting the sewage discharge control method of the embodiment can timely discharge the sewage in the first water tank to the second water tank according to the detection result of the water quality detection member when the water quality in the first water tank is poor, so as to significantly reduce the problem of affecting the normal use of the system and the health of the user caused by the water with very poor quality in the first water tank being supplied to the required structure (for example, the wet curtain). Moreover, the whole system is simple and efficient, can realize automatic discharge of sewage, is convenient for the user to clean, and reduces the maintenance cost.

[0056] The water circulation system is the execution carrier of the sewage discharge control method of the embodiment, and the water circulation system can be applied to humidifiers, cool fans and other humidifying devices. In the embodiment, the water circulation system is applied to a humidifier as an example.

[0057] As shown in Fig. 1 , the first water tank 1 and the second water tank 2 in the water circulation system are both suitable for containing a certain amount of water. Among them, the first water tank 1 is a water supply tank (or called a clean water tank), and the water stored in the inside is mainly used for water supply to the required structure (such as a wet curtain). The second water tank 2 is a sewage collection tank (or called a sewage tank), and the water stored in the inside is the sewage discharged from the first water tank 1. The first water tank 1 and the second water tank 2 are independently arranged, so that relatively clean water and sewage are stored separately to prevent cross contamination and improve water quality safety. The specific capacity of the first water tank 1 and the second water tank 2 can be selected and arranged according to the size and needs of the humidifying device. For example, the capacity of the first water tank 1 can be greater than that of the second water tank 2 to fully meet the water supply needs.

[0058] In the embodiment, in order to save the setting space, the first water tank 1 is arranged on the top of the second water tank 2 to facilitate the arrangement of the sewage discharge path from the first water tank 1 to the second water tank 2. Moreover, in order to make the structure more regular, the outer walls of the first water tank 1 and the second water tank 2 are flush, and the bottom wall of the first water tank 1 and the top wall of the second water tank 2 are shared to facilitate the structure arrangement. The first water tank 1 and the second water tank 2 are integrally arranged to facilitate manufacturing and simplify the assembly process.

[0059] The switch control member 3 can be opened or closed under control. When the switch control member 3 is opened, the first water tank 1 and the second water tank 2 are communicated, and the water in the first water tank 1 can be discharged to the second water tank 2 through the switch control member 3. When the switch control member 3 is closed, the first water tank 1 and the second water tank 2 are not communicated, and they are isolated and independent from each other.

[0060] In the embodiment, the switch control member 3 adopts a valve to facilitate control operation and has a relatively low cost. Specifically, the switch control member 3 is arranged at the bottom of the first water tank 1. When the valve is opened, the water in the first water tank 1 can be completely discharged into the second water tank 2, so that the sewage will not be left in the first water tank 1.

[0061] The water quality detection member is used for detecting the water quality clean index of the water in the first water tank 1. In the embodiment, the water quality detection member is arranged at the bottom of the first water tank 1. Alternatively, the water quality detection member is arranged on the switch control member 3, so as to improve the structural integration and facilitate installation.

[0062] The control unit is used for controlling the overall operation of the water circulation system. The signal input end of the control unit is electrically connected with the water quality detection member, and the signal output end of the control unit is electrically connected with the switch control member 3. After the detection result of the water quality detection member is sent to the control unit, the control unit determines whether to open the switch control member 3 according to the detection result.

[0063] Further, the water circulation system further comprises a water pump 4 and a wet curtain 5. The water pump 4 is arranged in the first water tank 1, and is used for pumping the water in the first water tank 1 and delivering the water to the wet curtain 5.

[0064] The water circulation system of the embodiment is applied to a humidifying device. The water circulation system further comprises a water pump 4 and a wet curtain 5. The water pump 4 is arranged in the first water tank 1, and is used for pumping the water in the first water tank 1 and delivering the water to the wet curtain 5. The water pump 4 is electrically connected with the control unit. The first water tank 1 is used for supplying water to the wet curtain 5. When the water absorption amount of the wet curtain 5 is saturated, part of the water will flow back. The backflow water will enter the first water tank 1 again, so as to form a water circulation process. After the water absorption amount of the wet curtain 5 is saturated, when the natural wind or the internal wind passes through the wet curtain 5, the water in the wet curtain 5 evaporates and takes away a large amount of latent heat in the air, so as to achieve the purpose of cooling and humidifying the space.

[0065] Specifically, the wet curtain 5 is arranged at the top of the first water tank 1, and at least part of the structure of the water pump 4 is arranged in the first water tank 1. The water inlet end of the water pump 4 is adapted to pump the water in the first water tank 1. Then, according to the design requirement, the water can be delivered to the wet curtain 5 by cooperating with a water delivery pipeline, a liquid distributor and the like. Since the water distribution process of the wet curtain 5 is the same as that of the prior art, no further description is given.

[0066] Further, the water circulation system further comprises a fan 6. The fan 6 is arranged close to the wet curtain 5. By arranging the fan 6, the air circulation in the humidifying device can be accelerated, the evaporation of the water in the wet curtain 5 can be promoted, and the humidifying efficiency can be improved. In the embodiment, the fan 6 is arranged at the top of the wet curtain 5, and the fan 6 is also electrically connected with the control unit.

[0067] Further, the water quality detection member is an ion concentration detection member, and the ion concentration detection member is used for detecting the ion concentration of the water in the first water tank 1.

[0068] In the embodiment, the water quality detecting member is an ion concentration detecting member. The ion concentration of the water in the first water tank 1 is detected to determine the water quality cleanliness of the water in the first water tank 1. The water quality cleanliness index is the ion concentration of the water. When the ion concentration of the water is high, it indicates that the water contains more impurities and the water quality cleanliness is poor. When the ion concentration of the water is low, it indicates that the water contains less impurities and the water quality cleanliness is good. The ion concentration detecting member is easy to install and set, which is beneficial to save manufacturing cost. Moreover, the ion concentration of the water is easy to detect, which can directly reflect the water quality and is beneficial to simplify the control method.

[0069] In the embodiment, a preset ion concentration threshold is set in advance. When the ion concentration of the water in the first water tank 1 is lower than the preset ion concentration threshold, the water quality cleanliness index meets the requirement. When the ion concentration of the water in the first water tank 1 is not lower than (equal to or higher than) the preset ion concentration threshold, the water quality cleanliness index does not meet the requirement.

[0070] In other embodiments, the water quality detecting member can also be a liquid level detecting member. The liquid level detecting member is used to detect the liquid level of the water in the first water tank 1. The liquid level of the water in the first water tank 1 can be used as the water quality cleanliness index. The water in the first water tank 1 is used for water supply circulation, i.e. the water in the first water tank 1 is supplied to the required structure and the backflow of the water from the required structure flows back to the first water tank. As the impurities continuously deposit, when the liquid level of the water in the first water tank 1 is very low (the liquid level of the water is lower than a preset liquid level threshold), the impurity density of the water in the first water tank 1 is high (the impurity content is thick), at this time, the water in the first water tank 1 has become sewage and the sewage in the first water tank 1 needs to be discharged to the second water tank 2. The liquid level detecting member is easy to install and set, which is beneficial to save manufacturing cost. Moreover, the liquid level of the water is easy to detect, which can directly reflect the water quality and is beneficial to simplify the control method.

[0071] At this time, a preset liquid level threshold is set in advance. When the liquid level of the water in the first water tank 1 is higher than the preset liquid level threshold, the water quality cleanliness index meets the requirement. When the liquid level of the water in the first water tank 1 is not higher than (equal to or lower than) the preset liquid level threshold, the water quality cleanliness index does not meet the requirement.

[0072] As shown in FIG. 1, the embodiment also provides a sewage discharge control method applied to a water circulation system. The water circulation system includes a first water tank 1 and a second water tank 2. The sewage discharge control method includes the following steps. Figs. 2-3

[0073] Step S01, starting;

[0074] Step S02, determining whether there is water in the first water tank 1;

[0075] Step S03, if not, issuing a water shortage signal and continuing to determine whether there is water in the first water tank 1; ​

[0076] Step S04, if yes, determining whether the water quality in the first water tank 1 meets the requirement;

[0077] Step S05, if yes, the first water tank 1 starts to supply water, and continues to determine whether the water quality in the first water tank 1 meets the requirement;

[0078] Step S06, if no, the water in the first water tank 1 is discharged to the second water tank 2, and it continues to determine whether there is water in the first water tank 1.

[0079] The sewage discharge control method can determine the water quality in the first water tank 1 before the first water tank 1 supplies water. When the water quality in the first water tank 1 does not meet the requirement, the water in the first water tank 1 is discharged to the second water tank 2. That is, when the water quality in the first water tank 1 is poor, the water in the first water tank 1 has become sewage, and the sewage is discharged to the second water tank 2 for storage. The embodiment can timely discharge the sewage in the first water tank 1 to the second water tank 2, thereby significantly reducing the problem of affecting the normal use of the system and the health of the user caused by the water with poor quality in the first water tank 1 being supplied to the required structure (for example, a wet curtain). Moreover, by reducing the impurities in the water, the service life of the water circulation system can be prolonged, and the maintenance cost can be reduced.

[0080] Further, the step S04, if yes, determining whether the water quality in the first water tank 1 meets the requirement, includes: determining whether the ion concentration of the water in the first water tank 1 is lower than a preset ion concentration threshold.

[0081] In the embodiment, the water quality detection member is an ion concentration detection member, and a preset ion concentration threshold is set in advance. When the ion concentration of the water in the first water tank 1 exceeds the preset ion concentration threshold, the water quality in the first water tank 1 is poor, and the water in the first water tank 1 has become sewage, which needs to be discharged to the second water tank 2.

[0082] In other embodiments, the step S04, if yes, determining whether the water quality in the first water tank 1 meets the requirement, includes: determining whether the liquid level of the water in the first water tank 1 is higher than a preset liquid level threshold. Since the water in the first water tank 1 is used for water supply circulation, as the impurities continuously deposit, when the liquid level of the water in the first water tank 1 is very low (the liquid level of the water is lower than the preset liquid level threshold), the impurity density of the water in the first water tank 1 is high (the impurity content is thick), and at this time, the water in the first water tank 1 has become sewage, which needs to be discharged to the second water tank 2. The liquid level detection member is easy to install and set, which is conducive to saving manufacturing cost, and the liquid level of the water is relatively easy to detect, which can directly reflect the water quality and is conducive to simplifying the control method.

[0083] Further, if no, in step S06, the water in the first water tank 1 is discharged to the second water tank 2, and the step of judging whether there is water in the first water tank 1 is continued, including: opening the switch control 3, and discharging the water in the first water tank 1 to the second water tank 2. The switch control 3 can be opened by the control unit, and the water in the first water tank 1 can be discharged to the second water tank 2 for storage through the switch control 3.

[0084] Further, if yes, in step S05, the first water tank 1 starts to supply water, and the step of judging whether the water quality clean index in the first water tank 1 meets the requirement is continued, including: opening the water pump 4, and the water in the first water tank 1 is pumped by the water pump 4 to the wet curtain 5, and the water backflow of the wet curtain 5 is backflowed to the first water tank 1. The water pump 4 can be opened by the control unit, and the water in the first water tank 1 can be conveniently pumped to the wet curtain 5. When the wet curtain 5 is saturated with water, part of the water will backflow, and these backflow water will enter the first water tank 1 again, forming a water circulation process.

[0085] Further, if yes, in step S05, the first water tank 1 starts to supply water, and the step of judging whether the water quality clean index in the first water tank 1 meets the requirement is continued, including: opening the water pump 4, and the water in the first water tank 1 is pumped by the water pump 4 to the wet curtain 5, and the water backflow of the wet curtain 5 is backflowed to the first water tank 1. The water pump 4 can be opened by the control unit, and the water in the first water tank 1 can be conveniently pumped to the wet curtain 5. When the wet curtain 5 is saturated with water, part of the water will backflow, and these backflow water will enter the first water tank 1 again, forming a water circulation process.

[0086] The sewage discharge control method of the embodiment will be described in detail. In the embodiment, the water quality detection member is an ion concentration detection member. The sewage discharge control method of the embodiment includes:

[0087] Step S01, start.

[0088] The humidifying device is started. The user can start the whole machine by operating the button on the humidifying device or the remote controller.

[0089] Step S02, judge whether there is water in the first water tank 1.

[0090] Whether there is water in the first water tank 1 is judged by a sensor detection method. The liquid level sensor, gravity sensor, etc. can be used to detect whether there is water in the first water tank 1. This process is the same as the prior art, and will not be described in detail.

[0091] Of course, in other embodiments, a liquid level standard can be set according to different needs, and then whether the water in the first water tank 1 is too little can be judged.

[0092] Step S03, if no, a water shortage signal is sent, and the step of judging whether there is water in the first water tank 1 is continued.

[0093] If there is no water or the water is insufficient in the first water tank 1, the whole machine sends a water shortage signal, such as through the lighting of an indicator light or the sounding of an alarm, to prompt the user to add water to the first water tank 1.

[0094] Step S04, if yes, it is determined whether the water quality clean index in the first water tank 1 meets the requirement.

[0095] If there is water or the water is sufficient in the first water tank 1, it is further determined whether the water quality clean index in the first water tank 1 meets the requirement. In this embodiment, the water quality clean index is the ion concentration of the water. The preset ion concentration threshold value can be set according to the product design requirement, which is not specifically limited in this embodiment.

[0096] Determining whether the water quality clean index in the first water tank 1 meets the requirement means determining whether the ion concentration of the water in the first water tank 1 is lower than the preset ion concentration threshold value. If it is lower, the water quality clean index in the first water tank 1 meets the requirement. If it is not lower (equal to or higher than), the water quality clean index in the first water tank 1 does not meet the requirement.

[0097] Step S05, if yes, the first water tank 1 starts to supply water, and it is continuously determined whether the water quality clean index in the first water tank 1 meets the requirement.

[0098] After the above determination, if the water quality clean index in the first water tank 1 meets the requirement, the water pump 4 is started, and the water in the first water tank 1 starts to supply water to the wet curtain 5 through the water pump 4. During the water supply process, the backflow water of the wet curtain 5 will enter the first water tank 1. Therefore, it is necessary to continuously determine whether the water quality clean index in the first water tank 1 meets the requirement during the above process.

[0099] Step S06, if no, the water in the first water tank 1 is discharged to the second water tank 2, and it is continuously determined whether there is water in the first water tank 1.

[0100] After the above determination, if the water quality clean index in the first water tank 1 does not meet the requirement, the switch control member 3 is started, and the water in the first water tank 1 is discharged to the second water tank 2 for storage through the switch control member 3. In this embodiment, the water in the first water tank 1 is completely discharged, so that the sewage is not left in the first water tank 1. Then, it is continuously determined whether there is water in the first water tank 1.

[0101] The sewage discharge control method of this embodiment can timely discharge the sewage to the second water tank 2 when the water quality in the first water tank 1 is relatively poor, thereby significantly reducing the problem of affecting the normal use of the system and the health of the user caused by the water with very poor water quality in the first water tank 1 being supplied to the required structure (such as the wet curtain). The sewage discharge control method of this embodiment solves the mildew and odor problem caused by the accumulation of bacteria and impurities due to the long-term use of the wet curtain.

[0102] It should be noted that when the second water tank 2 contains more sewage, the user can clean the sewage according to the machine prompt or self-observation, so as to continue to use subsequently.

[0103] The sewage discharge control method and the water circulation system of the embodiment are suitable for various scenes requiring water circulation and purification, such as industrial cooling systems, agricultural irrigation systems, household air conditioner humidification systems, etc.

[0104] The embodiment also provides a humidifying device, which comprises a shell and the above-mentioned water circulation system, and the water circulation system is arranged in the shell. The humidifying device can be a humidifier or a cool fan. In the embodiment, the humidifying device is a humidifier.

[0105] The humidifier of the embodiment also has structures and components possessed by existing humidifiers, which will not be described herein.

[0106] The humidifying device adopting the water circulation system of the embodiment can automatically discharge the sewage in the first water tank 1, ensure that the water participating in the water circulation is relatively clean, prolong the service life of the humidifying device, avoid the problem of mold and odor of the wet curtain, and facilitate the user operation and use.

[0107] In other embodiments, the water circulation system can be provided with ion concentration detection members and liquid level detection members at the same time, and the ion concentration and the liquid level in the first water tank 1 are detected at the same time, and the two detection results are combined and compared for analysis to determine whether the water quality clean index in the first water tank 1 meets the requirements.

[0108] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
