  ADVANTAGE OF THE INVENTION According to this invention, the air conditioner which supplies the air which increased oxygen concentration indoors without requiring piping and an expensive apparatus which connect the interior and the exterior can be provided.

  In the present invention, oxygen generated based on the reaction between a compound of an element belonging to Group 1A in the periodic table and water is mixed with air introduced by an air blowing means, thereby supplying air having a high oxygen concentration into the room. It is. A conventional air conditioner that supplies air with increased oxygen concentration using an oxygen separation membrane into the room supplies oxygen separated into the room by utilizing the difference in speed when gas molecules pass through the separation membrane. The separation membrane and the compression means necessary to send air into the membrane are expensive, and the piping equipment for oxygen supply or nitrogen exhaust, or both It is not suitable for indoor air conditioners that have the problem of being necessary and are desired to be small and inexpensive.

  According to the present invention, air with an increased oxygen concentration can be supplied into the room without the need for an air supply / exhaust pipe connecting the outside of the room or an expensive device. The oxygen generating means mounted on the air conditioner of the present invention generates oxygen by the reaction of a compound containing an element belonging to Group 1A of the periodic table with water, and the water required for the reaction with the compound is an air conditioner. It is possible to put in a container preliminarily placed in the machine, but it is possible to use a method in which the compound is introduced into water when oxygen is required, or a method in which an aqueous solution of the compound is used from the beginning. As the compound having oxygen generation ability, elements such as lithium, sodium, and potassium are preferably used. In particular, potassium superoxide is highly reactive with water, and instead of reacting in water, Since oxygen can also be generated by contact, a container for securing water is not necessary, which is convenient in a compact and simplified design of an air conditioner. When potassium superoxide is used, if it is placed in an air conditioner equipped with a humidifying means such as a humidifier, high-humidity air can be easily obtained and oxygen generation can be promoted.

  Moreover, if it arrange | positions to the air conditioner provided with the dehumidification means, it will become possible to utilize the water | moisture content obtained by dehumidification as water used for reaction with a compound. There is no restriction | limiting in the utilization form of this water, Any use of the water for dissolving a compound and the water for humidifying air may be sufficient.

  The oxygen generating means using sodium peroxocarbonate as a raw material in the present invention generates oxygen by the decomposition of hydrogen peroxide generated when dissolved in water. There is no particular limitation such as a method of dissolving in water and a method of adding necessary amount to water when necessary. The water container may have any shape, but for example, if it is elongated in a cylindrical shape, it is suitable for placement in a small air conditioner because a small gap can be used effectively. In general, it is known that an aqueous solution of hydrogen peroxide promotes oxygen generation by contacting an enzyme or a catalyst. For example, catalase or manganese dioxide is added to an aqueous sodium peroxocarbonate solution as an oxygen generating means in the present invention. Thus, hydrogen peroxide can be decomposed to obtain oxygen. Manganese dioxide may be in powder form or in bulk, but it is poor in contact efficiency because it settles or deposits in an aqueous solution. If oxygen is consumed and replaced with a new aqueous solution, manganese dioxide is added again. This increases the consumption of materials.

  Such a problem can be avoided by using a method in which manganese dioxide is fixed on the carrier in a film shape and brought into contact with hydrogen peroxide. The material and shape of the support are not particularly limited, but ceramic honeycombs have a small volume and a large surface area, so that they are excellent not only in durability but also in oxygen generation efficiency. Hydrogen peroxide easily decomposes and releases oxygen in a basic aqueous solution, so the aqueous solution can be neutralized by adding an acid such as sulfuric acid in advance to a basic sodium peroxocarbonate solution. If it is left, autolysis of hydrogen peroxide can be suppressed.

  In the oxygen generating means of the air conditioner of the present invention, the rate of oxygen generation can be controlled by varying the degree of contact of a catalyst carrier such as manganese dioxide with an aqueous sodium peroxocarbonate solution, which is necessary when necessary. An amount of oxygen can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings.

As shown in a schematic cross-sectional view in FIG. 1, the air conditioner 1 is basically composed of a blowing means 2, a humidifying means 3, and an oxygen generating means 4, and humidifying means is introduced into the air guided to the air conditioner 1 by the blowing means 2. 3 is used to contain a large amount of moisture, and the humidified air is guided to the oxygen generation means 4 filled with potassium superoxide to generate oxygen by a chemical reaction. The generated oxygen-containing air has an increased oxygen concentration. To be supplied indoors.

(Example 2)
As shown in the schematic perspective cross-sectional view of FIG. 2, the air conditioner 11 has a blower unit 12 and an oxygen generator unit 13 as a basic configuration. Oxygen 15 generated from the oxygen generating means 13 is mixed with the air guided by the air blowing means 12 and supplied to the room in a state where the oxygen concentration is increased, and the oxygen generating means 13 is supplied with the sodium peroxocarbonate aqueous solution 14 and the dioxide dioxide as shown in FIG. Based on the result of Reference Example 1, the amount of oxygen 15 generated per unit time is controlled by changing the contact depth of the manganese dioxide support 16 to the sodium peroxocarbonate solution 14 based on the result of Reference Example 1. Can do.

  As a reference example, as shown in FIG. 4, a hydrogen peroxide-containing solution obtained by mixing 200 mL of water and 10 g of sodium peroxocarbonate in an Erlenmeyer flask 21 and then neutralizing this mixed solution by adding 98% sulfuric acid. The manganese dioxide carrier 23 in which manganese dioxide is fixed on the ceramic honeycomb substrate in the form of a film is introduced into the hydrogen peroxide-containing solution 22 to decompose hydrogen peroxide to generate oxygen 24. A manganese dioxide carrier test piece in which 0.7 g of manganese was supported in the form of a film was prepared, and the amount of oxygen generated when charged into a hydrogen peroxide-containing solution was measured using a graduated cylinder 25. As a result, 150 mL of oxygen was generated in 1 minute. Moreover, if the amount of manganese dioxide supported was increased, the amount of oxygen generated per unit time was also increased proportionally. Thereby, it is possible to adjust the oxygen generation amount according to the contact amount of manganese dioxide with sodium peroxocarbonate.

  The air conditioner of the present invention is useful as a device that supplies air with an increased oxygen concentration into the room without the need for piping or an expensive device connecting the interior and the exterior.
