Description

Technical Field

[0001] The present invention belongs to the field of new energy vehicle battery management, and specifically relates to an antibacterial and odor-removing dehumidification device based on gas separation technology and a control system thereof. Background Art

[0002] Low carbon and environmental protection are necessary measures for sustainable development in my country. More and more people are beginning to choose transportation tools such as buses, passenger cars, and subways. Coupled with the continuous improvement of people's living standards, the requirements for the riding environment are getting higher and higher. Especially for buses and passenger cars, on the one hand, their operating time is long; on the other hand, the passengers are more complex and need to eat and drink while riding. This will cause an increase in the amount of bacteria in the car and even the appearance of odor. When affected by the high temperature and high humidity environment, the types and number of colonies in the car increase significantly, and the degree of odor becomes more serious. Not only does it affect the riding comfort of the car, but it will also have a serious impact on the physical and mental health of the human body in the long run. Therefore, it is very necessary to develop a system with automatic sterilization and deodorization.

[0003] Air conditioning is one of the essential components of buses and one of the important evaluation indicators that affect the comfort of passengers. Different regions have different climatic characteristics. When buses run in high temperature and high humidity for a long time, the types and number of bacteria in the car and air conditioner will increase significantly, and unpleasant odors will appear. In order to achieve better insulation and noise reduction effects, the existing automotive air conditioner covers are all pasted with open-hole insulation cotton. The cover is a protective device installed on the air conditioner and is also one of the parts that are in direct contact with the outside world. Especially for the cover of the evaporation part, it is often necessary to paste an insulation board (open hole / closed hole) inside the cover due to the influence of low temperature. Among them, the closed-hole insulation board can play a better sealing role and reduce the probability of bacteria being located in the cover and growing inside it. But it does not work for noise reduction. The use of closed-hole insulation board can achieve better noise reduction function, but it is easy to breed bacteria and produce product odor. Long-term exposure to high humidity will breed more bacteria and produce corresponding musty odors. The more bacteria on the cover, the more bacteria and odor concentration will enter the car with the fan and air duct. In the long run, it will affect the comfort of passengers and also have different degrees of impact on their physical and mental health. The sterilization and deodorization system is one of the necessary means to improve the comfort of the in-vehicle environment, and it is also an important measure to support the high-end and internationalization of the whole vehicle.

[0004] The technical means adopted by the prior art are: First: Use ventilation devices to achieve ventilation of the entire vehicle, thereby improving the control quality inside the vehicle.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1As shown, an antibacterial and odor-removing dehumidification device based on gas separation technology includes an air-conditioning cover assembly 1, a cover mounting hole 5 is opened on the air-conditioning cover assembly 1, bolts are arranged in the cover mounting hole 5, and the air-conditioning cover assembly 1 is installed on the air conditioner by the bolts.

[0021] Insulation cotton 2 is arranged in the air conditioner cover assembly 1, through holes are arranged on the insulation cotton 2, and magnet assemblies 3 are arranged around the insulation cotton 2. The magnet assembly 3 can fix the active gas-conditioning membrane group 4 as a whole on the air conditioner cover assembly 1 and seal and wrap the insulation cotton 2 completely, so that a sealed environment is formed between the air conditioner cover assembly 1 and the active gas-conditioning assembly 4. At the same time, for safety reasons, bolt columns 8 are reserved on the air conditioner cover assembly 1, and fixing holes are also added around the active gas-conditioning module 4, and the installation fastening of the active gas-conditioning membrane group 4 is strengthened by bolt fastening. The active gas-conditioning module 4 here is a nitrogen-oxygen separation membrane, which is a prior art.

[0022] Furthermore, a multifunctional sensor 6 is arranged inside the thermal insulation cotton 2, which can realize real-time monitoring of target objects such as odor (sour smell, etc.), colony count, oxygen concentration, etc. Each multifunctional sensor 6 is connected in parallel and interconnected with the control module 9 through the wiring harness 7. The multifunctional sensor 6 can feed back the detection signal to the control module 9, and the control module 9 is wirelessly connected to the vehicle control system to realize signal alarm, thereby reminding the driver to replace the active gas-controlled membrane group 4.

[0023] In addition, in order to further reduce the growth of bacteria, a passive gas-conditioning component 13 is installed between the sealed environment formed by the air-conditioning cover component 1 and the active gas-conditioning component 4. The passive gas-conditioning component 13 is also the gas-conditioning fresh-keeping box and its gas-conditioning component disclosed in CN216187725U, which is a prior art. The passive gas-conditioning component 13 is arranged in the sealed environment to play a role of secondary gas filtration. A solenoid valve 12 and a micro vacuum pump 11 are installed at a suitable position of the air-conditioning cover component 1 outside the sealed environment. The micro vacuum pump 10 is connected to the solenoid valve 12 by a vacuum tube 11. The oxygen in the sealed environment can be extracted by controlling the opening of the micro vacuum pump 10 and the solenoid valve 12, so that there is only a trace amount of oxygen and a large amount of nitrogen, carbon dioxide and other gases in the sealed environment, creating an oxygen-suppressing environment, reducing the peculiar smell and moldy smell caused by the growth of bacteria, providing good air quality in the car, and improving the comfort of passengers.

[0024] Furthermore, in order to ensure the strength, installation efficiency and service life of the active gas-controlled membrane group 4, a reinforcing plate 14 is provided on the active gas-controlled membrane group 4, and the active gas-controlled membrane group 4 and the reinforcing plate 14 are designed as an integral component. Preferably, different sound wave through holes 15 are provided on the reinforcing plate 14 to facilitate the passage of sound waves and maintain a certain air permeability.

[0025] like Figure 2As shown, the magnet assembly 3 includes a fixed magnet 31 fixed on the air conditioner cover assembly 1, and the fixed magnet 31 is fixedly connected to the air conditioner cover assembly 1 through a magnet fixing buckle 32. It also includes a movable electromagnet 33 integrated with the active gas-conditioning membrane group 4, and a sealing ring 34 is provided between the fixed magnet 31 and the movable electromagnet 33. Under normal circumstances, the movable electromagnet 33 is attracted by the magnetic attraction of the fixed magnet 31. At this time, the sealing ring 34 has a certain amount of compression, but it is still breathable. When powered on, the movable electromagnet 33 can suck in the fixed magnet 31, so that the sealing ring 34 is in an extreme compression state, and the airtight seal is better.

[0026] In order to facilitate the overall installation of the movable electromagnet 33 and the active gas-adjusting membrane group 4, the four edges of the active gas module 4 are designed as a hollow structure, so that the movable electromagnet 33 can be inserted into the edge 35 of the active gas-adjusting module 4, thereby realizing the overall disassembly and replacement of the entire active gas-adjusting membrane group 4. In order to ensure the disassembly of the fixed magnet 31, the fixed magnet 31 is designed to be T-shaped, and a guide rail mechanism is reserved at a preset position on the air-conditioning cover assembly 1. The disassembly of the fixed magnet 31 is achieved by using a slider guide rail mechanism, which improves efficiency while also ensuring the installation stability of the magnet. The installation positions of the fixed magnet 31 and the movable electromagnet 33 are interchangeable.

[0027] Combination Figure 3 Analysis: Since the vehicle air conditioner has two left and right covers, an active gas conditioning component 4 is set on each air conditioner cover assembly 1, that is, the left cover assembly is provided with a left active gas module 41, a left vacuum tube 42 and a left solenoid valve 43; the right cover assembly is provided with a right active gas module 44, a right vacuum tube 45 and a right solenoid valve 46. During assembly, the micro vacuum pump 10 is installed on the inside of the air conditioner, and the left solenoid valve 43 and the right solenoid valve 46 can be installed on the inside of the air conditioner simultaneously, or they can be installed on the air conditioner cover assembly 1. The right active gas module 44 and the left active gas module 41 are respectively installed in the sealed environment inside the left and right evaporation covers 16. A micro vacuum pump 10 is used in conjunction with two solenoid valves to realize the simultaneous extraction of oxygen from the two covers, or to extract air from one side alone. It should be noted that, in the overall air conditioner, the evaporator also includes an evaporator assembly 17 and a condenser assembly 18.

[0028] A method for controlling bacteriostasis, odor removal and dehumidification based on gas separation technology comprises the following steps: Step 1: When the air conditioner is turned on and operates normally, the multifunctional sensor 6 in the air conditioner cover assembly 1 monitors the gas in the sealed environment in real time; Step 2: The multifunctional sensor 6 detects the oxygen concentration and the number of bacteria in the sealed environment; on the one hand, it determines whether the number of bacteria inside (including special odors, etc.) is greater than the preset value. When the detection result is greater than the preset value, the system alarms and reminds the driver to replace the insulation cotton 2 and the active gas conditioning module 4; if the monitoring result is less than the preset value, the detection cycle continues; on the other hand, the multifunctional sensor 6 can detect the amount of oxygen in the sealed environment. When any of the multifunctional sensors 6 in the left and right covers alarms, the micro vacuum pump 10 and the corresponding solenoid valve start to work to pump oxygen; when the oxygen content is less than the preset value, the corresponding solenoid valve stops working if it is powered off; otherwise, the solenoid valve and the micro vacuum pump 10 continue to work. When the detection feedback values ​​of the multifunctional sensors 6 on both sides are less than the preset value, the solenoid valve and the micro vacuum pump 10 stop working, and the sensor continues to monitor in real time.

[0029] On the one hand, the system can effectively block oxygen, dust, moisture and other elements from entering the insulation cotton, reducing the probability of bacterial growth and odor generation. At the same time, it can also realize real-time monitoring of bacteria and odor and system alarm, facilitate the replacement of the gas conditioning module, and improve the intelligence and high-end level of the whole vehicle.

[0030] The advantage of the present invention is that it uses existing gas separation technology to block oxygen, moisture, etc. outside the lid insulation board, creating an antibacterial environment, reducing bacterial growth, odor products and moisture entering the insulation board, thereby solving the problems of air conditioning odor, moldy odor, high bacteria count, poor air quality, etc.

[0031] The present invention designs a gas-controlled membrane group that is easy to load and unload and installs it on the insulation board (open / closed hole) of the lid. In actual operation, only hydrogen and nitrogen can pass through, and it can play a good barrier role for oxygen and water molecules. In this way, on the one hand, the amount of bacteria on the insulation board can be reduced, and the growth of bacteria can be inhibited by blocking oxygen, thus playing a good role in sterilization, deodorization and dehumidification.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
