Abstract

PURPOSE:To predetermine comfortable humidity in conformity with room temperatures and perform humidification control so as to obtain comfortable humidity at that temperature based on the room temperature and relative humidity data. CONSTITUTION:Target relative humidity predetermined in conformity with room temperatures is stored in a memory section 3. An arithmetic operation 4 compares and calculates the target relative humidity stored in the memory section 3 in conformity with the room temperature detected with a temperature sensor 1 and the currently available indoor relative humidity detected by a relative humidity sensor 2. To comply with the result of the arithmetic operation section 4, a control section 5 controls the operation of a humidification heater and embodies comfortable environmental humidity which can be felt physically in the entire temperature region.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier for humidifying a room.

0002

[Prior Art] Conventionally, this type of humidifying device has generally used an ultrasonic method using an ultrasonic vibrator, a heating method (hot humidification) in which water is evaporated and humidified using a heating device, etc.
Many are equipped with a heating device to heat the room. Most of these humidifiers are of a type that performs continuous humidification at a predetermined capacity, and recently, types with built-in humidity sensors have also been released.

0003

[Problems to be Solved by the Invention] In such conventional humidifying devices, continuous humidifying type continues to humidify even when the humidity in the room is sufficiently high, causing discomfort to the user in high humidity conditions. Not only that, but there were also problems in that it could exceed the saturation state and even reach a state of dew condensation. Also, even if the humidity sensor is built-in, the humidity is controlled to a specified humidity or the humidity set by the user, regardless of the room temperature. However, there was a problem in that it gave a dry feel in low temperature regions (Generally, in low temperature regions, the absolute humidity is low, so the relative humidity value at which the human body feels comfortable is higher than in high temperature regions. ).

[0004] The present invention solves the above problems, and aims to provide a comfortable humidity environment in all temperature ranges by changing the controlled humidity depending on the room temperature.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a humidifier that humidifies a room, a room temperature sensor that detects the temperature of the room, and a relative humidity sensor that detects the relative humidity of the room. , a storage unit that stores a predetermined target relative humidity corresponding to the room temperature, a calculation unit that performs a comparison calculation between the target relative humidity and the current relative humidity, and a humidification unit that receives the result of the calculation unit. The solution to this problem is that it is equipped with a control section that controls the operation of the vehicle.

[0006]

[Operation] The present invention uses the above-mentioned problem-solving means to input room temperature and relative humidity from a sensor, and calculate a predetermined target relative humidity (comfortable humidity at that temperature) corresponding to the room temperature stored in the storage unit. The humidity in the room is controlled by calling and comparing it with the current relative humidity, and the humidification can be controlled to create a stable and comfortable condition with no humidity fluctuations and no dew condensation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in the figure, a room temperature sensor 1 detects the temperature of the room, and a relative humidity sensor 2 detects the relative humidity of the room. It is installed inside the main body of the device. Storage part 3
stores a target relative humidity predetermined according to the room temperature, inputs the output of the room temperature sensor 1, and outputs a target relative humidity value corresponding to that value. The calculation unit 4 compares the target relative humidity with the current relative humidity value and calculates the humidity deviation. The calculation unit 4 outputs phase control data corresponding to the amount of humidification to the phase control unit (control unit) 5, and controls the phase of the humidification heater (humidification unit) 6 to achieve the target relative humidity. On the other hand, the heating control section 7 controls the heating capacity of the hot air heater to either high, low, or off, and uses this output to control the energization of the heater 8 and the blower motor 9.

The hot air heater is provided with a humidifying outlet 10, a cartridge tank 11 for supplying humidifying water, and a heating hot air outlet 12, and the heating control section 7 controls heating switching by controlling the number of energized heaters. There are three levels: strong, weak, and off. The humidifying section uses a heating method, and the water supplied from the cartridge tank 11 is heated to a metal tube 13 as shown in FIG. 6, and heat and evaporate it to perform humidification.

The operation of the above configuration will be explained. When the humidification operation is started, first, in order to ensure the start-up time of the humidification heater 6, a 100% phase output is output from the phase control section 5 to the humidification heater 6, and this state is maintained for 3 minutes. In this embodiment, the capacity of the humidifying heater 6 is set to 250 W, and the humidification amount is about 250 cc/H with 100% energization.

[0011] When the 3-minute 100% humidification period ends,
Next, room temperature data is input from the room temperature sensor 1 to the storage section 3. Then, a target relative humidity corresponding to the room temperature is selected from target relative humidity data (comfortable humidity) preset in the storage section 3 and output to the calculation section 4. The calculation unit 4 also receives current relative humidity data from the relative humidity sensor 2, and performs a comparison calculation with the target relative humidity.
The deviation Eo between the two is calculated. Here, the value of the target relative humidity according to the room temperature is shown in Fig.
As shown in Figure 2, the curve was set so that the humidity is high in the low temperature range and becomes 40 to 50%, which is said to be the comfortable humidity level, as the temperature goes up to the high temperature range.

Then, in accordance with the humidity deviation Eo, the current carrying capacity of the humidifying heater 6 corresponding to the required amount of humidification at that time is output, and is converted into a necessary phase angle by the phase control section 5 to set the phase of the humidifying heater 6. As a result, the relative humidity in the room is maintained at a comfortable level over the entire temperature range.

On the other hand, the heating control section 7 controls the heater 8 and the blower motor 9 according to the heating capacity (strong/weak/off) selected by the user.

[0014]

[Effects of the Invention] As is clear from the above embodiments, according to the present invention, the target relative humidity stored in the storage section and the current relative humidity detected by the relative humidity sensor are compared and calculated, and based on the result, Since the operation of the humidifier is controlled, discomfort and condensation caused by excessive humidification are eliminated, and
Since the humidity is controlled to be comfortable depending on the room temperature, comfortable humidity can be achieved in any temperature range.
