Abstract

PURPOSE:To obtain an air conditioner capable of adjustment to an appropriate ion quantity, by disposing a discharge wire at an outlet port of a blowing circuit for circulating air, generating negative ions by a high AC voltage system, and varying the quantity of ions generated by regulating the quantity of air blown. CONSTITUTION:An air conditioner equipped with an ion generator comprises a discharge unit 1 disposed at a place in an outlet grille 4 constituting a blowing circuit of the air conditioner 11, a high AC voltage unit 2 disposed in a power supply box 8, and an ion sensor 3 arranged at a place of a front grille 6. While the quantity of ions is decreased with an increase in the quantity of contaminating fine particles in a room, negative ions are supplied by generating negative ions, and the amount of ions (in terms of the number of negative small ions) in the room is varied to within the range of 200-300 ions/CC by regulating the blowing power of the air conditioner 11. The amount of negative small ions in the room is thereby brought nearly to the refreshing ion quantity level at highlands or hot springs.

Description

[Detailed description of the invention] Industrial application field of the present invention (1) The air supplied from the blower circuit is supplemented with negative ions alone or with negative ions and positive ions (＼Increase the ions that have decreased in the air. In addition, the present invention provides an air conditioner equipped with an ion generator that can adjust the amount of ions to an appropriate level using an ion sensor. There is a certain power (general home air conditioners equipped with ion generators are not sold (t Mana))
The generation method is a direct current high voltage type, and the one that generates only negative ions has a certain level of power.The one that generates both negative ions and positive ions is 1.%.Problems to be solved by the invention East office, a closed room with little ventilation.
Meeting I! Indoors When there are many people in a home, etc., carbon dioxide is emitted as they breathe. Small ions, such as cigarette smoke and dust, increase, and small ions decrease, especially when smoking cigarettes, and decrease to 1/2 to 115 of the outdoor air ions. Currently, commercially available ion generators generate only negative ions, and the amount of generated ions is different from the ion distribution outdoors, and they generate only large amounts of negative ions. However, since the generation method uses a DC high voltage device to generate negative ions from a discharge needle, there is a problem that a lot of dust adheres to products and surrounding equipment.

Means for Solving the Problems The Present Invention In order to solve the above problems, a discharge unit is provided in the air blower circuit of an air conditioner, and an AC high voltage device is installed in the power supply section of the air conditioner. The amount of ions in the room can be increased by generating negative ions to replace the ions that decrease as the air temperature increases.
The present invention is configured by installing a discharge unit in the air blower circuit of an air conditioner, and installing an AC high voltage device in the power supply section of the air conditioner. By generating negative ions and positive ions, the ions that decrease with the increase in indoor pollutant particles are replenished.The amount of ions in the room can be reduced depending on the strength of the air conditioner's ventilation conditions. For each small positive ion, use an appropriate amount (e.g. 200-30
00 pieces/CC), and the ratio of negative ions to positive ions is set to 1:0.8 to 1.00, for example. In addition, the present invention is configured by installing a discharge unit in the air blower circuit of an air conditioner, installing an AC high voltage device in the power supply section of the air conditioner, and installing an ion sensor in the intake section. An ion sensor detects the amount of ions in the room and changes the voltage to generate an appropriate amount of negative ions and replenish the ions that decrease with the increase in particulates.
Even if the air conditioner's air blowing conditions change, small negative ions will keep the amount of ions in the room at an appropriate level (e.g. 200 to 1000 ions/C).
In addition, the present invention is configured by installing a discharge unit in the air blowing circuit of an air conditioner, installing an AC high voltage device in the power supply section of the air conditioner, and installing an ion sensor in the intake section. By detecting the amount of ions in the room with an ion sensor and changing the voltage, an appropriate amount of negative ions and positive ions are generated to replenish the ions that decrease with the increase in pollutant particles, changing the air conditioner's air blowing conditions. However, the amount of ions in the room is changed to, for example, 200 to 1000 small ions/CC, and the ratio of negative ions to positive ions is l:o, 8 to 1.
．． 2. The effect generated by the above means is as follows. In the present invention? ,t
A discharge unit is installed in the air conditioner's blower circuit, and an AC high-voltage device is installed in the air conditioner's power supply.This device prevents the generation of negative ions from the ions that decrease with the increase in indoor pollutant particles. replenishes negative ions by
The amount of ions in the room can be controlled by the strength of the air conditioner's air blowing conditions.
By changing the number of negative small ions to 200 to 3000/CC, the amount of negative small ions indoors will be on the same level as the gentle ion amount found on plateaus and hot spring areas. Negative ions have a sedative effect, relieve irritation, and are said to have health effects and improve work ability. By using a high voltage device, we can generate ions without charging the product itself in a negative or positive state.We can also suppress the adhesion of dust in the indoor air to the product. By changing the wind to a light breeze, it is possible to change the amount of ions L&K to low.Additionally, according to the present invention, a discharge unit is installed in the air blower circuit of the air conditioner.1 An AC high voltage device is installed in the power supply section of the air conditioner. This system generates negative ions and positive ions to replenish the ions that decrease with the increase in indoor pollutant particles. The amount of each negative or positive small ion ``a'' is 200 to 3000 pieces/CC.
By changing the amount of negative or positive small ions in the room (to the same level as the gentle ion amount in a plateau or hot spring area), the effect of negative ions has a sedative effect. It is said that it relieves feelings of irritation, has health effects and improves work ability.
: By generating at 0.8 to 1.2, it is possible to secure the amount of small negative and positive ions close to the natural state.Also, by using an AC high voltage device, the product itself can be kept in a negative or positive biased state. Since it can generate ions without being charged, it can also suppress the adhesion of dust in the indoor air to products.

In addition, by changing the air blowing conditions from strong wind to weak wind to breeze, the ion amount L&I=l=1. In addition, the present invention is configured by installing an AC high voltage device in the air conditioner's power supply section, and installing an ion sensor in the intake section of the front grill. An ion sensor detects the amount of ions in the room and changes the voltage to generate an appropriate amount of negative ions to replenish the ions that decrease with the increase in pollutant particles. is also a small negative ion, and the amount of ions in the room is 200 to 10
By changing the amount to 00 pieces/CC, the amount of small negative ions indoors can be reduced to the same level as the gentle ion amount found on the plateau. It is said to have health effects and improve work ability by relieving symptoms such as anxiety, and it is said that similar effects can be obtained by using AC high voltage equipment.
The ion sensor can generate ions without charging the air conditioner itself in a negative or positive state.It can also suppress the adhesion of dust in the indoor air to products. By detecting the amount of ions in the room and changing the voltage, an appropriate amount of negative ions can be generated. Invention 4i: A discharge unit is installed in the blower circuit of the air conditioner. An AC high voltage device is installed in the power supply section of the air conditioner. An ion sensor is installed in the intake section of the front grill. By detecting the amount of ions in the room with an ion sensor and changing the voltage, an appropriate amount of negative ions and positive ions are generated to replenish the ions that decrease with the increase in pollutant particles. Change the amount of ions in the room to 200 to 1000 small ions/CC with each small ion being negative or positive, and the ratio of negative ions to positive ions to 1:0.8 to 1.
．． By generating 2, the amount of negative or positive small ions indoors is comparable to the amount of gentle ions found on the plateau. It is said to have health effects and improve work ability by eliminating irritation, etc. Similar effects can also be obtained by setting the ratio of negative ions to positive ions to 1:0, 8 to 1.2. By generating small amounts of negative and positive ions that are close to the natural state, by using an AC high voltage device, ions can be generated without charging the air conditioner itself in a negative or positive state. It is possible to suppress the adhesion of dust in the air to the product.Also, even if the air conditioner's air blowing conditions change, the ion sensor detects the amount of ions in the room and changes the voltage, allowing both negative and positive The number of ions that can be generated in an appropriate amount The amount of small negative or positive ions in the room can be stably maintained at 200 to 1000 ions/CC without large fluctuations.
