Abstract

An oxygen-enriched capsule apparatus, the oxygen-enriched capsule apparatus comprising an external unit (1) and a capsule (2). A refrigerant compressor cooling system (11) may be used to cool mixed air consisting of interior air and exterior air (fresh air), and when an oxygen-producing system (12) is operating, a portion of cool air is drawn into the oxygen-producing system (12) to produce oxygen, produced oxygen and another portion of cool air in a wind intake pipe being mixed, and then blown into a sealed relaxation space via an interior wind outlet (211). Given that an air source of the oxygen-producing system (12) includes a portion of fresh air, then, by means of controlling operation of the oxygen-producing system (12), oxygen concentration in a room may be increased to an appropriate oxygen-enrichment value, and, in combination with temperature control of the refrigerant compressor cooling system (11), a healthy, constant-temperature, oxygen-enriched and comfortable environment may be created in a sealed relaxation space. In addition, mixed air enters the oxygen-producing system (12) only after being cooled, and the mixed air may be dehumidified in the cooling process, hence mixed air entering the oxygen-producing system (12) has decreased humidity, preventing damage to the oxygen-producing system (12) caused by excess humidity.

Description

Oxygen-enriched space capsule device

[0001] The present invention belongs to the technical field of health care equipment, and in particular to an oxygen-enriched space capsule device.

Background technique

[0002] In modern society, most of them are homes, offices and hotels, and most of them are equipped with air-conditioning systems. Most of the air conditioning system air is only a closed internal circulation system. In this closed space, people will continuously consume oxygen in the indoor air and discharge more carbon dioxide, which leads to the lack of oxygen in the human body. When the person is in an anoxic state, the body's aerobic metabolic rate will decrease, anaerobic glycolysis will be strengthened, the body's metabolic efficiency will decrease, immunity will decrease, sleep disorders, mental decline, and memory loss will occur.

[0003] There are two ways to solve indoor hypoxia in the market:

[0004] (1) Install a fresh air system. The advantages are: Increase the oxygen content in the air for large spaces such as large theaters, conference halls, etc. The disadvantages are: It can only maintain the general oxygen concentration level, and can not increase the oxygen concentration in the indoor air; the installation is troublesome (the overall decoration of the house should be considered); the cost is high and the general rate is very low.

[0005] (2) Household oxygen generator. The advantages are: no installation, low price. The disadvantages are: need to take over to the breathing position of the human body, resulting in people not being able to move at will. It does not directly improve the oxygen concentration of indoor air. If used in an air-conditioned room, the nitrogen separated from the oxygen generator is still in the room.

[0006] In addition, in terms of air quality, although some air conditioners currently have air purification and dehumidification functions, they are not perfect in air humidity regulation. Due to the refrigeration function of the air conditioner itself, the skin of the person staying in the air-conditioned room for a long time is very dry. Although many people now buy humidifiers to humidify the air, humidifiers require extra water to properly humidify the work. Adding water is easy to forget or people are not happy. Outside of people, artificial watering does not meet the future development direction of smart homes.

[0076] However, in another modified embodiment, the control system may also be one and disposed on the external unit 1. All control is implemented by the control system on the external unit 1.

[0077] In the oxygen-enriched capsule device of the above embodiment, the air sensor group 24 is configured to monitor the air in the closed rest space. The quality and the collected data are sent to the control system 23, and the control system 23 controls the activation or suppression of the refrigerant compression refrigeration system 11, the oxygen generation system 12, the humidification system 17, and the auxiliary heating system 230 based on the data to realize the oxygen-enriched space. Constant temperature, constant humidity and oxygen-rich environment in the cabin.

[0078] The principle of thermostat is as follows:

[0079] In a hot weather, when a temperature drop 吋 (cooling 吋) is required, the temperature detected by the temperature sensor is higher than a set value 吋, the control system 23 controls the refrigerant compression refrigeration system 11 to start; The temperature detected by the temperature sensor is less than the set value 吋, and the control system controls 23 that the refrigerant compression refrigeration system 11 is turned off; thereby, the temperature of the closed rest space can be kept constant at a set value (set by the remote controller). The refrigeration process of the refrigerant compression refrigeration system 11 is as follows: The refrigerant (refrigerant) discharged from the compressor 117 is converted into a low-temperature low-pressure liquid refrigerant through the expansion valve 120, and the low-temperature low-pressure liquid refrigerant is evaporated into a gaseous state through the evaporator 119a, and the absorption is carried away by evaporation. The heat of the air inside the casing 119c. The evaporator fan 11% blows cold air. The gaseous refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant after being compressed by the compressor 117, and the high-temperature and high-pressure gaseous refrigerant is condensed into a liquid state through the condenser 118, and a large amount of heat is released from the same, and the condenser fan behind the condenser 118 blows the heat out of the chamber. In this infinite loop, the indoor heat is discharged to the outside, thereby reducing the indoor temperature.

[0080] In cold weather, when temperature rise (heating) is required, the temperature detected by the temperature sensor is less than a set value, the control system 23 controls the auxiliary heating system 230 to be turned on; The detected temperature is higher than the set value 吋, and the control system 230 controls the auxiliary heating system to be turned off; thereby, the temperature of the closed rest space can be kept constant at a set value (set by the remote controller). The heating process of the auxiliary heating system 230 is as follows: the auxiliary heating system 23 extracts indoor cold air from the indoor air inlet 212, and performs heating, and the air heated by the auxiliary heating system 230 is blown through the indoor air outlet 211. To the enclosed rest space.

[0081] The principle of constant oxygen is as follows:

[0082] The person's breathing continuously consumes oxygen in the capsule 2, and the oxygen concentration detected by the oxygen sensor is less than a set value, the control system 23 controls the oxygen system 12 to be activated; The oxygen concentration is higher than the set value 吋, the control system 23 controls the oxygen system to be closed; thereby, the oxygen concentration of the closed rest space can be kept constant at a set value (oxygen-rich value), and the set value is greater than or equal to a minimum The oxygen-rich value, that is, the set value is 21% or more.

[0083] The control system 23 senses the indoor oxygen concentration through the oxygen sensor, calculates the required amount of oxygen, and precisely controls The oxygen system 12 is introduced into a portion of the mixed air for oxygen extraction and then sent to the chamber. When the indoor oxygen concentration reaches the set value, the control system 23 intelligently controls the oxygen production of the pressure swing adsorption oxygen system. This allows the room to reach a healthy, constant temperature, oxygen-rich comfort environment.

[0084] The principle of constant humidity is as follows:

[0085] The water tank 171 is disposed below the 119a evaporator 119a, and the water droplets cooled by the evaporator 119a of the refrigerant compression refrigeration system 11 are concentrated in the sewage zone 175 of the lower water tank 171, and the sewage passes through the precipitation and activated carbon. The filter filters the particles and organic contaminants into the cleaning zone 176. The ultrasonic high frequency oscillator 173 further atomizes the water in the water purification zone 176 into water vapor, and the atomized water vapor enters the air inlet pipe. 4 The water gas is sent into the room by the evaporator fan 11%. The control system 23 controls the humidification system 17 to be activated when the humidity detected by the humidity sensor is less than a set value, and the control system 23 controls the humidity when the humidity detected by the humidity sensor is higher than a set value. The humidification system 17 is turned off. Thus, the control system 23 intelligently adjusts the amount of atomization after the humidity sensor senses the change in humidity in the capsule to maintain a constant humidity in the capsule 2.

[0086] In addition, two-stage air purification is achieved by providing the air filter 13 and the negative ion purification system 29. In the first stage, when it is necessary to introduce outdoor air for oxygen extraction, the dust particles are filtered by the air filter 13. In the second stage, the negative ion purification system 29 releases the negative ions and actively attacks indoors to find suspended particulate contaminants and settle them. Due to the diffuse nature of the air, negative ions will exist in every corner of the room, and there is no problem of purifying the dead angle. According to the experimental data, the smaller the particle size negative ions in the air, the better the purification effect of the particles with smaller diameter, so the removal effect on PM2.5 is better. Negative ions can quickly neutralize the coke, "secondhand smoke", soot and fly ash that are positive ions in the air.

[0087] According to the oxygen-enriched capsule device of the embodiment of the invention, the refrigerant compression refrigeration system can be used for cooling the mixed air of indoor air and outdoor air (fresh air), and when the oxygen system works, part of the cold air is introduced into the oxygen system. The system prepares oxygen, and the produced oxygen is mixed with another part of the cold air in the inlet duct and then blown from the indoor air outlet to the closed rest space. Since the air source of the oxygen system contains part of the fresh air, by controlling the oxygen system to work, the oxygen concentration of the indoor air can be increased to a suitable oxygen-rich value, combined with the temperature control of the refrigerant compression refrigeration system, which can be closed at rest. Create a healthy, oxygen-rich and comfortable environment in the space. In addition, the mixed air is cooled before entering the oxygen system, and the mixed air can be dehumidified during the cooling process. Therefore, the humidity of the mixed air entering the oxygen system is lowered to avoid excessively high Humidity causes damage to the oxygen system.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. Within the scope.
