At this time, some of the inversion patterns 152 corresponding to the number to be displayed among the 7-segment inversion patterns 160 shown on the liquid crystal panel 151 are maintained in a transparent state, and only the remaining inversion patterns 152 are converted into an opaque state, so that The light of the backlight 154 is transmitted through only through the partial inversion pattern 152 maintained in the state, and since the background screen 153 is in an opaque state in which light cannot be transmitted, the distinction between the contrast becomes more distinct.

As an example, when a control code corresponding to '90.3' is input through the liquid crystal panel 151, '90.3' is displayed in reverse.

In another embodiment, a button 171 is further provided so that when a specific button 171 is pressed, numbers such as temperature, humidity, and a timer may be displayed on the display unit 150. When you press the button inscribed with the temperature symbol'℃', it displays the room temperature or the temperature of the water (W). When you press the button with the water droplet shape, it displays the current indoor humidity, and the button with the'T' When pressed, the number related to the timer is displayed. Basically, it is desirable to allow the current humidity (T) to be displayed.

As shown in FIGS. 12 and 13, a heating means 190 for mounting the main body 100 or raising the temperature of the water W may be further included. The heating means 190 has a flat bottom surface and has a protruding protrusion formed in the center so as to mount the main body 100, and a case having a flat shape is provided so as to be in close contact with the floor. Therefore, the heating means serves as a cradle for mounting the main body 100 and is utilized as a heating means 190 for transferring heat at the same time. Here, it is common to use a circuit provided with a heating wire, a hot plate, and a resistor to be used as the heating means 190 for generating heat. When a current flows through the circuit, the heating wire, the heating plate, and the resistor dissipate heat, so that it is used as a means for transferring heat by contacting the bottom of the main body 100. (Technology corresponding to the process of receiving power and heat transfer is known. As it is true, detailed descriptions are omitted.) However, not only does it require a lot of power to generate initial heat, but also a lot of power is required to maintain the temperature of the water.

As a product distributed on the market, Zojirushi's heated humidifier consumes 305~410W when humidifying, while 985W when heated. It can be seen that electricity bills of around 20,000 won are generated, excluding certain variables, assuming that it operates within 8 hours on average per day.

In order to solve this problem, energy can be more efficiently utilized by including an electricity saving circuit 300 capable of saving energy.

A heating means 190 that is intimately coupled to the bottom of the main body 100 and generates heat to boil the water W is further included,

The heating means 190 is mounted on one side of the upper surface of the circuit board 302 and mounted on the other side of the upper surface of the circuit board 302 and a plurality of resistor parts 320 having different heat generated according to resistance values, It is connected between the circuit control unit 301 for determining whether the heating temperature of the resistor has reached a preset temperature, and the resistor unit 320 and the circuit control unit 301 according to a signal from the circuit control unit 301 An electricity saving circuit 300 including a plurality of relay units 310 that are turned on or off is included, and the resistor unit 320 connected to any one of the relay units 310 according to the determination of the circuit control unit 301 It is characterized in that heat is generated in. Through this, it may be characterized in that energy is saved by making the amount of electric power when heating and the amount of electric power during warming different from each other.

As an embodiment to which the electric power saving circuit 300 is applied, the relay unit 310 includes a first relay 311 and a second relay 312, and the resistor unit 320 includes a first resistor 321 And a second resistor 322.

When power is applied, the circuit control unit 301 recognizes that it is operating for the first time, and transmits a signal for applying power so that a contact point is attached to the first relay 311 in order to rapidly increase the temperature of the water W. Thereafter, when a contact is attached to the first relay 311, a current flows through the connected first resistor 321. At this time, the operation is performed at a level at which an amount of power corresponding to about 800 to 950 W is generated, and the temperature of the water (W) can be quickly heated from 0°C to 120°C. Thereafter, when the temperature sensor unit 110 measures the water (W) temperature, and when the temperature and humidity control unit 112 determines that it has reached 120°C, the circuit control unit 301 is the contact point of the first relay 311 And a contact is attached to the second relay 312 so that a current flows through the second resistor 322. In this case, the amount of power is input to about 300 to 400W so that the temperature of the water (W) does not fall below 60°C. In this way, in order to keep the water (W) at an appropriate temperature and keep warm, not only the amount of power is efficiently used through the control process of transmitting signals at all times so that the contact points are attached to the first and second relays 311 and 312. No, you can save.

As the other heating means 190, a form of dissipating a lot of heat within a short time, such as induction heating, PTC heating, heating wire, hot plate, and nichrome wire may be applied.
