The power supply unit 130 receives power from the outside of the housing 110, and supplies the power to the planar heating element 112 inside the housing 110. The power supply unit 130 may be configured to be supplied with power by charging by having a rechargeable secondary battery directly connected or charged by a household power source. When directly connected by a home power source, a power adapter may be provided. When equipped with a secondary battery, the charging power is connected to the home power, or configured to supply power to the planar heating element 112 by receiving power wirelessly from a wireless power supply around the transparent water heater 100. Can be.

FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1. According to FIG. 2, the housing 110 includes a front part 111 and a rear part 114 that are parallel to each other. Between the front portion 111 and the rear portion 114 is formed in a sealed space filled with water (W).

As an example, the carbon nanotube layer in the color changing layer (320-1, 320-2, 320-3, 320-4, 320-5, 320-6) is not implemented at room temperature or implemented by green or the like When the heat is generated, it may be configured to sequentially appear the color according to the temperature by discoloration, such as yellow and red. The color change layers 320-1, 320-2, 320-3, 320-4, 320-5, and 320-6 may be disposed at different positions along the heat exchange channel part 320 to prevent water in the housing 310 from flowing. Depending on the location, it can be visually identified as having different temperatures.

In addition, the color change layers 320-1, 320-2, 320-3, 320-4, 320-5, and 320-6 may provide specific information through letters or symbols.

In order to operate the transparent water heater 600, a home network 700 may be provided outside. However, not all of these elements are necessary and may be configured in different combinations in some cases.

The controller 680 controls the operation of the planar heating element 688 and thus may be referred to as a heating controller. The controller 680 provides various functions or effects under the control of various input / output means connected thereto.

The input unit 681 is implemented in an operable form, and receives an input signal related to the operation of the transparent water heater 600 and provides it to the controller. The input unit 681 may be implemented in a form of manipulation using a dial method, a manipulation in a touch manner, a manipulation in a click manner, or the like. In order to improve the user interface, the input unit 681 may be implemented to be directly associated with the display unit 689 described later.

The input unit 681 may be input in the form of desired supply temperature of hot water or supply time. In the former case, a temperature set by a combination with a temperature sensor 682 to be described later is realized. In the latter case, the controller 680 has a built-in timer and supplies electric energy to the planar heating element 688 for a set time.

The person detecting unit 684 may be implemented in the form of a sensor, for which a known sensor such as a heat sensor or an ultrasonic sensor may be applied. The controller 680 controls whether the planar heating element 688 generates heat based on the result detected by the person detector 684. That is, when there is a person, the controller 680 may apply power to the planar heating element 688 to preheat the water so that hot water may be supplied immediately.

The timer 685 is configured to supply the controller 680 with information about a set time or the like.

The voice recognition unit 686 receives the voice from the user and identifies it. As an example, when the user says "warm water", the voice recognition unit 686 receives the signal, identifies the voice command related to the control of the transparent water heater 600, and applies a signal to the controller 680. The controller 680 supplies electric energy to the planar heating element 688 according to a voice command of the user. Since the voice recognition unit 686 controls the transparent water heater 600 without the user directly operating by hand, there is an advantage of high convenience.

The voice output unit 687 outputs information input by the input unit 681, information recognized by the voice recognition unit 686, or various notification signals as voice signals. The voice output unit 687 may be formed in the form of an acoustic transducer or the like that contacts the dynamic speaker or the housing to directly vibrate the housing.

The signal transmitted to and received from the home network 700 by the wireless transceiver 690 is transmitted to the controller 680, and the controller 680 controls whether the planar heating element 688 is operated. The wireless transceiver 690 may include any one of an infrared receiver, a voice recognition unit, or a short range wireless communication unit.

The controller 680 may receive a lighting signal from the home network 700 through the wireless transceiver 690, and may supply electrical energy to the planar heating element 688 when the lighting signal is generated. For example, when the user turns on the bathroom lamp to enter and exit the bathroom with a transparent water heater, the home network 700 sends a lighting signal of the bathroom lamp to the wireless transceiver 690, and the controller 680 In response to the lighting signal through the wireless transmitter / receiver 688, electric energy is supplied to the planar heating element 688. As such, by heating the planar heating element 688 automatically through the home network 700 and the wireless transceiver 690, sufficient time for water to be preheated can be ensured.

The controller 680 receives weather information from the home network 700 through the wireless transceiver 690, and determines whether to supply electric energy to the planar heating element 688 based on the weather information. That is, when the weather information received from the home network 700 is cold weather, the controller 680 operates the planar heating element 688. On the contrary, when the weather information received from the home network 700 is warm weather in which hot water supply is unnecessary, the controller 680 does not operate the planar heating element 688 to prevent unnecessary waste of power.

An example of adjusting the hot water supply temperature by the control unit 680 will be described. First, it is checked whether water is introduced through the inlet. When water enters through the inlet, the initial temperature of the water is received from the temperature sensor 682. The controller 680 checks a target temperature (a value input by a user or a value determined as a default), and then calculates an electric energy supply amount in consideration of the flow rate and the initial temperature. When the electric energy to be supplied is calculated, the planar heating element 688 is heated accordingly according to the current set number of stages, that is, one stage or two stages.

The controller 680 may control the planar heating element 688 to preheat the water therein at a predetermined time interval by a timer. That is, even when the user turns on the water of the water heater, the user can prevent the surprise due to the cold water by using the preheated water immediately.

The power supply unit 691 may directly use a home power source or may include a rechargeable battery, and may further include a solar cell as a power generation source. In addition, the power supply unit 691 may be configured to receive power from the wireless power supply device to supply the device.
