Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. Although the present embodiment is described by taking a wall-mounted air conditioner as an example, the present invention can also be applied to indoor units of other types of air conditioners such as a ceiling type air conditioner and a cabinet type air conditioner.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", etc. are based on the directions or positional relationships shown in the drawings, which are for convenience of description only, and do not indicate or imply that the device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
After the air conditioner has been operated for a long time, bacteria are generated in the air conditioner, and the bacteria, viruses, etc. are introduced into the indoor space along with the air while the air conditioner is operated. In the operation process of the air conditioner, the door and the window are usually closed, and after a long time, especially in a series of environments such as seafood shops and the like where bacteria are easy to breed, a large amount of bacteria can be bred in the air of an indoor space. These bacteria and viruses can affect the health of the user. In addition, the oxygen content in the air in the indoor space is also reduced, which is likely to cause discomfort to people. To this end, the air conditioner of the present invention is provided with a hydrogen peroxide generator that generates hydrogen peroxide molecules capable of sterilizing and disinfecting an indoor space. According to the control method, the hydrogen peroxide generation device and the fan are controlled to be started according to the content of the first bacteria in the air of the indoor space, the hydrogen peroxide generation device and the fan can be controlled to be started according to the actual situation of the indoor space, the sterilization effect can be ensured, the air condition of the indoor space is improved, and electric energy can be saved.
First, a possible implementation of the drain duct of the wall-mounted air conditioner of the present invention will be described with reference to fig. 1.
As shown in fig. 1 and in the orientation shown in fig. 1, the wall-mounted air conditioner includes an indoor unit of an air conditioner including a drain pipe 1, the drain pipe 1 is appropriately thickened, the drain pipe 1 is made of a relatively hard material (e.g., a metal material such as a hard plastic or an aluminum plate), or the strength of the drain pipe 1 is enhanced by adding a reinforcing rib or the like. A partition plate 11 is arranged in the drainage pipeline 1, and the partition plate 11 extends along the length direction of the drainage pipeline 1 to divide the interior of the drainage pipeline 1 into two parts, namely a drainage channel 12 at the upper side and an induced draft channel 13 at the lower side. The drain passage 12 is used for discharging condensed water of the indoor unit of the air conditioner to the outside.
The filter screen 2, the hydrogen peroxide generation device 3 and the fan 4 are sequentially arranged in the induced air channel 13 along the induced air direction, the filter screen 2 can be a fiber filter screen 2, a steel wire mesh and the like, the shape of the filter screen is approximately similar to the cross section of the induced air channel 13, the filter screen is arranged along the axial direction perpendicular to the induced air channel 13, and impurities in fresh air can be filtered. The fan 4 may be a cross flow fan 4, an axial flow fan 4, or the like, which is used to introduce fresh air from the outside into the indoor space via the air inducing channel 13. The hydrogen peroxide generating device 3 is configured to convert water and oxygen in the air into hydrogen peroxide molecules.
Because the drainage pipeline 1 usually extends into the outdoor space, under the action of the fan 4, the outdoor fresh air can enter the indoor space through the air inducing channel 13 after impurities are filtered by the filter screen 2, so that the oxygen content in the air of the indoor space can be increased, and the air condition of the indoor space can be improved. Meanwhile, when fresh air flows through the hydrogen peroxide generation device 3 in the induced air channel 13, the hydrogen peroxide generation device 3 converts water and oxygen in the fresh air into hydrogen peroxide molecules, and the hydrogen peroxide molecules can cover the surfaces of harmful pathogens, such as enterococcus faciale (VRE), Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Candida albicans, Enterobacter and the like, and can effectively inactivate COVID-19 viruses. Therefore, the hydrogen peroxide molecules generated by the hydrogen peroxide generation device 3 can remove bacteria and viruses in the fresh air, and simultaneously can enter the indoor space along with the fresh air to sterilize and degerming the indoor space, so that a better degerming effect can be obtained. Obviously, the hydrogen peroxide generator 3 may be disposed on the downstream side of the fan 4 in the air inducing direction, and those skilled in the art can flexibly select the hydrogen peroxide generator as long as fresh air can flow through the hydrogen peroxide generator before entering the indoor space.
The hydrogen peroxide generator 3 can convert water and oxygen into hydrogen peroxide molecules by electrolysis, photocatalysis, or the like. In the case of photocatalytic methods, the catalyst can be a mixed metal matrix with a catalyst coating, e.g., a polymeric nitrogen carbide metal/semimetal coordination complex, using a multi-wavelength lamp as the light source, e.g., a lamp that produces light having a wavelength of 300nm to 2000nm, such that upon irradiation of the catalyst, water and oxygen can form hydrogen peroxide molecules on the surface of the catalyst. The skilled person can flexibly select the specific arrangement of the hydrogen peroxide generator 3 according to the specific application scenario, as long as water and oxygen can be converted into hydrogen peroxide molecules.
It should be noted that the partition 11 may also divide the interior of the drainage pipeline 1 into two parts along the horizontal direction, and those skilled in the art may flexibly select the partition according to the specific application scenario.
As shown in fig. 1, an opening 14 is provided as a communicating structure between the drain passage 12 and the induced air passage 13, and condensed water in the drain passage 12 passing through the opening 14 can enter the upstream end of the hydrogen peroxide generation device 3 in the induced air direction. After the fan 4 is turned on, part of the condensed water can reach the hydrogen peroxide generation device 3 together with the fresh air, and then react with oxygen in the fresh air at the hydrogen peroxide generation device 3 to be converted into hydrogen peroxide molecules. Because water is additionally provided, the amount of water which is one of reaction raw materials is increased, so that more hydrogen peroxide molecules can be generated, fresh air and indoor space can be better disinfected and sterilized, and the air condition of the indoor space can be better improved.
In a possible embodiment, a valve is provided at the opening 14, which is closed when no condensate needs to be introduced, and the hydrogen peroxide generator 3 can convert only water and oxygen in the fresh air into hydrogen peroxide molecules. When the condensed water needs to be introduced, the valve is opened, the condensed water in the drainage channel 12 enters the induced air channel 13 through the opening 14, the condensed water and the oxygen are carried to the hydrogen peroxide generation device 3 by the fresh air in the induced air channel 13, and the condensed water and the oxygen are converted into hydrogen peroxide molecules, so that more hydrogen peroxide molecules can be generated by introducing the condensed water. Obviously, no valve may be provided at the opening 14.
It should be noted that the communicating structure may also be a communicating pipe disposed between the groove 15 and the induced air channel 13, and the valve may be disposed at any position of an end or a middle of the communicating pipe, and those skilled in the art may flexibly select the communicating structure according to a specific application scenario.
A groove 15 capable of storing condensed water is arranged in the drainage channel 12, and the condensed water flows to the groove 15 along the drainage channel 12 and then is stored in the groove 15. An opening 14 is provided at the bottom of the groove 15, and the accumulated condensate in the groove 15 can enter the induced air channel 13 through the opening 14. It is obvious that the above-mentioned groove 15 may not be provided in the drain channel 12.
A liquid level detection device, such as a floating ball type liquid level meter, a static pressure type pressure sensor, a capacitance type liquid level meter, an ultrasonic liquid level sensor and the like, is also arranged in the groove 15. The level of the condensed water in the groove 15 can be detected by the liquid level detection device.
As shown in fig. 1 and according to the orientation shown in fig. 1, a waterproof boss 5 is further disposed in the induced air channel 13, the waterproof boss 5 is disposed on the upstream side of the filter screen 2 as viewed in the induced air direction, the waterproof boss 5 has a gradually rising slope, and the highest point of the waterproof boss 5 is located on the downstream side of the opening 14. Thus, the condensed water entering the air inducing channel 13 through the opening 14 is partially carried to the hydrogen peroxide generator 3 by the fresh air flowing through the air inducing channel 13 and partially condensed to the lower side of the air inducing channel 13. The condensed water condensed to the lower side of the induced air channel 13 flows to the outside of the room under the action of the waterproof boss 5, so that the condensed water is prevented from flowing to the hydrogen peroxide generation device 3 along the induced air direction, and the hydrogen peroxide generation device 3 is further prevented from being short-circuited or even damaged. Of course, the waterproof boss 5 may not be provided in the air induction passage 13.
In this embodiment, the wall-mounted air conditioner is further provided with a bacteria content detector by which the bacteria content in the indoor space can be detected. The bacteria content detector can be arranged at any possible position of an air inlet, an air outlet or an air duct of the air-conditioning indoor unit, and also can be arranged on two end plates at two ends of the air-conditioning indoor unit, and the bacteria content detector can be flexibly selected by a person skilled in the art.
Obviously, the wall-mounted air conditioner may not be provided with the bacteria content detector, and in some occasions, such as public occasions like seafood shops, railway stations, markets and the like, the bacteria content detector is required to monitor the bacteria content of the public occasions in real time. When the bacteria content is needed, the wall-mounted air conditioner can directly call the detection result of the bacteria content detector.
The bacteria content detector may be a PM2.5 sensor, and since bacteria and viruses usually cannot enter a free state by themselves, they usually need to be carried or adsorbed on a carrier for propagation, and particulate matters in the air are usually the best carriers for bacteria and viruses. Therefore, the content of the PM2.5 in the air of the indoor space can be detected in real time through the PM2.5 sensor to reflect the content of the bacteria in the air of the indoor space, i.e. the higher the content of the PM2.5 in the air, the higher the content of the bacteria in the air is, and the lower the content of the PM2.5 in the air is, the lower the content of the bacteria in the air is.
Of course, the bacteria content detector can be set in other forms, and the person skilled in the art can flexibly select the bacteria content detector according to the specific application scenario. For example, the bacteria content detector is a laser colony measuring instrument, an air dust bacteria detector, an ATP fluorescence detector, or the like, and when detecting the bacteria content in the air, the air dust bacteria sampler is used for sampling, and the air dust bacteria sampler may be an FKC-I type air dust bacteria planktonic sampler, a porous inhalation type dust bacteria sampler, a JYQ type air dust bacteria planktonic sampler, or the like. In the sampling process by using the air dust and bacteria sampler, bacteria in the air are collected in a culture dish in the air dust and bacteria sampler, and after the bacteria are cultured, the bacteria content in the air can be detected and determined by using the bacteria content detectors such as the laser colony measuring instrument, the air dust and bacteria detector, the ATP fluorescence detector and the like.
Taking the bacteria content detector as an example of a laser colony measuring instrument, the number of colony groups in the air detected by the laser colony measuring instrument is, that is, the bacteria content in the air is expressed by the number of colony groups. For example, the number of colonies detected in the air was 2500EA/M3、2000EA/M3And the like.
In this embodiment, the wall-mounted air conditioner further includes a control module, the control module is respectively connected to the bacteria content detector, the hydrogen peroxide generation device and the fan, and the control module can receive the detection result detected by the bacteria content detector and control the hydrogen peroxide generation device and the fan based on the detection result. It should be noted that, such a control module may be physically a control chip of the wall-mounted air conditioner itself, may be a controller specially used for executing the method of the present application, or may be a functional module or a functional unit of a general controller.
The following describes possible implementations of the control method of the air conditioner according to the present invention by taking the bacteria content detector as an example of a laser colony measuring instrument and referring to fig. 2 to 4.
As shown in fig. 2, in one possible embodiment, the control method of the present invention includes:
step S100: obtaining a first bacterial content in air of an indoor space;
step S200: judging whether the content of the first bacteria exceeds a first preset value;
step S300: and selectively controlling the hydrogen peroxide generation device and the fan to be started based on the judgment result.
In step S100, a first bacteria content (e.g., a colony population number) of 3000EA/M in the air of the indoor space is obtained based on the bacteria content detector3。
In step S200, it is determined whether the first bacteria content exceeds a first preset value based on the first bacteria content obtained in step S100. For example, the first bacteria content (colony population number) is 3000EA/M3The first preset value is 2500EA/M3. As another example, the first bacteria content (colony population number) is 1500EA/M3The first preset value is 2500EA/M3。
In step S300, the hydrogen peroxide generator and the fan are selectively controlled to be turned on based on the determination result in step S200.
Through such control mode, whether open hydrogen peroxide generating device and fan are confirmed based on how much of first bacterium content in the air of indoor space, just so can also follow the actual situation of indoor space more and control the introduction of new trend and hydrogen peroxide molecule, can both ensure the degerming effect, improve the air condition of indoor space, can practice thrift the electric energy again.
As shown in fig. 3, in a possible embodiment, after obtaining the obtained first bacteria content, i.e. after step S100, the control method of the present invention further comprises:
step S310: if the first bacteria content exceeds a first preset value, giving an alarm and sending prompt information of whether to start a hydrogen peroxide generation device and a fan;
step S320: judging whether the received first feedback information is 'yes', if yes, executing step S340; if not, go to step S330;
step S330: sending a reminder of the current first bacteria content;
step S340: and controlling the hydrogen peroxide generation device and the fan to be started.
In step S310, based on the first bacteria content obtained in step S100, the first bacteria content is compared with a first preset value, if the first bacteria content exceeds the first preset value, for example, the first bacteria content (colony group number) is 3000EA/M3The first preset value is 2500EA/M3In this case, the bacteria content in the indoor space is high, and therefore, the sterilization treatment is required. At the moment, an alarm is given out to remind the user that the content of bacteria in the air of the current indoor space is higher. And simultaneously sending prompt information of whether to start the hydrogen peroxide generating device and the fan.
Of course, when the content of the first bacteria exceeds the first preset value, the hydrogen peroxide generation device and the fan can be directly controlled to be started, and a person skilled in the art can flexibly select the hydrogen peroxide generation device and the fan according to a specific application scene.
The alarm may be performed by a voice, an alarm sound, a light flashing, or a combination of two or more of the above-described modes. Specifically, when the alarm is given by voice, the user may be informed that the first bacteria content exceeds the first preset value, or the specific value of the first bacteria content, or the user may be informed that the specific value of the first bacteria content and the first bacteria content exceeds the first preset value at the same time. The skilled person in the art can flexibly select a specific alarm mode according to a specific application scenario, as long as the purpose of reminding the user can be achieved.
After the prompt message of "whether to start the hydrogen peroxide generation device and the fan" is sent, whether the received first feedback message is "yes" is judged, if not, it indicates that the user does not agree to improve the air condition of the indoor space by starting the hydrogen peroxide generation device and the fan, at this time, a prompt of the current first bacteria content is sent, and step S330 is executed. Informing the user of the specific value of the first bacteria content in the air of the current indoor space by sending the first bacteria content, e.g., the first bacteria content (colony group number) is 3000EA/M3The user can know that the content of bacteria in the current air is high and needs to take corresponding treatment measures, and the user can open the window or perform forced ventilation and the likeTo reduce the bacteria content in the air of the indoor space.
Certainly, when the received first feedback information is "no", the user can be reminded of the bacteria and the high content in the air of the current indoor space by giving an alarm, flickering light and the like.
If yes, the user agrees to improve the air condition of the indoor space by turning on the hydrogen peroxide generator and the fan, and at this time, the hydrogen peroxide generator and the fan are controlled to be turned on, and step S340 is performed. Outdoor fresh air is introduced through the fan, and the oxygen content in the indoor space is improved. And will reach the water and the oxygen conversion of hydrogen peroxide generating device department through hydrogen peroxide generating device and become the hydrogen peroxide molecule, the hydrogen peroxide molecule enters into the interior space along with the new trend together, disinfects, degerming the processing through the hydrogen peroxide molecule to new trend and interior space to improve the air condition of interior space, promote user experience.
If the first bacteria content does not exceed the first preset value, it indicates that the bacteria content in the indoor space is not very high, and at this time, no treatment is needed.
Through such control mode to can control opening of hydrogen peroxide generation device and fan according to current bacterial content and user's actual wish, thereby can be better for the indoor space degerming, promote user experience.
As shown in fig. 4, in one possible embodiment, the control method of the present invention further includes:
step S410: after the hydrogen peroxide generation device and the fan are controlled to be started, the valve is controlled to be opened;
step S420: sending prompt information of whether to enter an autonomous mode;
step S430: judging whether the received second feedback information is 'yes', if yes, executing step S450; if not, go to step S440;
step S440: controlling the fan to run at a preset rotating speed;
step S450: obtaining a second bacterial content in the air of the indoor space again;
step S460: based on the second bacteria content, the rotational speed of the fan is adjusted.
In step S410, after the hydrogen peroxide generating device and the fan are controlled to be turned on, i.e., after step S340, the valve is controlled to be opened. After the valve is opened, the condensed water in the drainage channel can enter the induced draft channel through the opening.
In step S420, after the control valve is opened, and the hydrogen peroxide generator and the fan are already opened, a prompt message of "whether to enter the autonomous mode" is sent, that is, step S420 is executed after step S410.
It should be noted that, the step S410 and the step S420 may also be executed simultaneously, or the step S420 is executed first and then the step S410 is executed, and those skilled in the art can flexibly select the step S410 according to a specific application scenario.
In step S430, after the prompt message of "whether to enter the autonomous mode" is sent, that is, after step S420, it is determined whether the received second feedback message is "yes", and if not, it indicates that the user does not want to enter the autonomous mode, at this time, the fan is controlled to operate at the preset rotation speed, that is, step S440 is executed. The fan is controlled to operate at a fixed preset rotating speed, for example, 180r/min, outdoor fresh air is introduced through the fan, hydrogen peroxide molecules generated by the hydrogen peroxide generation device are brought into the indoor space, the indoor space is disinfected and sterilized through the hydrogen peroxide molecules, and the oxygen content in the indoor space is improved through the fresh air, so that the aim of adjusting the air condition of the indoor space is fulfilled.
It should be noted that, if the received second feedback information is "no", the user may also set the rotation speed of the fan autonomously.
If yes, it indicates that the user agrees to enter the autonomous mode, and at this time, the second bacteria content in the indoor space is obtained again by using the bacteria content detector, and step S450 is performed.

Just so can adjust the rotational speed of fan according to current actual bacterium content, then adjust the fresh air volume and the hydrogen peroxide volume of sending into the indoor space to can obtain better degerming effect.
In a possible implementation manner, the rotating speed of the fan is increased along with the increase of the second bacteria content, the higher the second bacteria content is, which indicates that more hydrogen peroxide molecules are needed to achieve the sterilization effect, at this time, the rotating speed of the fan needs to be increased, more fresh air needs to be introduced, so that more oxygen participates in the reaction, more hydrogen peroxide molecules are generated, and thus, the better sterilization effect can be achieved. For example, the second bacteria content (colony population number) is 2200EA/M3And controlling the rotating speed of the fan to be 180 r/min. As another example, the second bacteria content (colony population number) is 3000EA/M3The rotation speed of the fan is controlled to be 250r/min, and the like.
It should be noted that the rotation speed of the fan may not be increased with the increase of the second bacteria content, for example, the second bacteria content (colony group number) may be less than 2500EA/M3When the bacteria colony is detected, the rotating speed of the fan is controlled to be 180r/min, and the second bacteria content (colony group number) is more than 2500EA/M3And controlling the rotating speed of the fan to be 250r/min, and the like. The person skilled in the art can flexibly adjust the rotation speed of the fan according to the second bacteria content according to the specific application scenario, as long as the second bacteria content (colony group number) of the indoor space is less than or equal to 2000EA/M3And (4) finishing.
Through above-mentioned control mode, after opening hydrogen peroxide generating device and fan, whether get into autonomic mode according to user's will selection to the rotational speed of fan can be controlled better, and then the quantity of the hydrogen peroxide molecule that hydrogen peroxide generating device generated is controlled better, thereby can disinfect, the degerming to the interior space better, improves the air condition of interior space.
In the present invention, the prompt message of "whether to turn on the hydrogen peroxide generator and the fan" and "whether to enter the autonomous mode" may be sent to the user by voice, text, or voice + text, or by combining the above modes with light or alarm. The prompt message can be directly sent to the wall-mounted air conditioner, the user can return the feedback message in a voice reply mode, and the feedback message can also be returned through a remote controller, a mobile phone, a tablet personal computer and other mobile terminals which are communicated with the wall-mounted air conditioner. Obviously, the prompt message may also be directly sent to a remote controller, a mobile phone, a tablet computer, or other mobile terminals communicating with the wall-mounted air conditioner, and the user returns the feedback message through the mobile terminals. Those skilled in the art can flexibly select a sending object and a sending mode of the prompt message according to a specific application scene as long as the user can obtain the prompt message and return the feedback message.
