Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

A display device 1 according to an embodiment of the present application is described below with reference to fig. 1 to 16.

Fig. 1 shows a schematic structural diagram of a display device 1 according to an embodiment of the present application. The display device 1 may be used for a water heater.

As shown in fig. 1, the display device 1 includes a display panel 10, and the display panel 10 is provided with a control module (not shown), a water temperature input module 11 and an indication module (i.e., a plurality of water temperature indication lamps 12).

Specifically, the water temperature input module 11 is used for inputting a set water temperature, and the set water temperature can be switched among a plurality of preset gears.

The number of preset gears and the specific numerical value of each preset gear can be set according to actual conditions. For example, the plurality of preset gears may include four, and the four preset gears are respectively a first preset gear, a second preset gear, a third preset gear and a fourth preset gear from low to high. The first preset gear can be 45 ℃, the second preset gear can be 55 ℃, the third preset gear can be 65 ℃, and the fourth preset gear can be 75 ℃.

For example, as shown in fig. 1, the water temperature input module 11 may be a button, and the user inputs the set water temperature by operating the button. Specifically, the keys may be mechanical keys or touch keys or other types of keys. The user can switch the set water temperature between the plurality of preset gears once by operating the key once, and if the key is not operated again within a preset time interval (for example, 3 seconds), the current preset gear is determined to be the preset gear of the input set water temperature, and the water temperature input module 11 generates a corresponding electric signal and sends the electric signal to the control module.

The indicating module may include a plurality of water temperature indicating lamps 12, and the plurality of water temperature indicating lamps 12 correspond to a plurality of preset gears one to one. For example, the number of the water temperature indicating lamps 12 may be four, and the four water temperature indicating lamps correspond to the first preset gear, the second preset gear, the third preset gear and the fourth preset gear respectively in a one-to-one manner.

The control module is respectively electrically connected with the temperature sensor and the water temperature input module 11 so as to control the display of the plurality of water temperature indicating lamps 12 according to the actual water temperature and/or the preset gear of the set water temperature of the water heater detected by the temperature sensor. Wherein, the display of the water temperature indicator lamp 12 may include flashing and normally on, and the water temperature indicator lamp 12 is not displayed in the off state. In other examples of the present application, the control module may control the water temperature indicator 12 to display different colors to distinguish different display states.

Illustratively, the water heater comprises a liner, and a temperature sensor can be arranged near the liner or the water outlet so as to detect the temperature of water in the liner in real time. The temperature sensor generates a temperature signal according to the detection result and sends the temperature signal to the control module, wherein the temperature signal can comprise the actual water temperature of the water heater.

Further, the control module can be electrically connected with a power panel device of the water heater, and the power panel device is used for controlling the on-off of a heating device of the water heater. For example, the control module sends an on signal to the power panel device after receiving the set water temperature sent by the water temperature input module 11. Responding to the starting signal, the power panel device connects the heating device into the circuit to control the heating device to heat the water in the inner container. For another example, the control module sends a closing signal to the power panel module when the actual water temperature reaches the set water temperature. In response to the closing signal, the power panel device disconnects the heating device from the circuit to control the heating device to stop heating the water in the inner container.

It should be noted that the control module can only control the display of the water temperature indicator 12 according to the actual water temperature of the water heater. For example, the control module may sequentially determine whether the actual water temperature reaches the preset gear in a sequence from low to high. Specifically, if the actual water temperature does not reach the preset gear, the water temperature indicator lamp 12 corresponding to the preset gear is controlled to flash; and if the actual water temperature reaches the preset gear, controlling the water temperature indicator lamp 12 corresponding to the preset gear to be normally on, and judging whether the actual water temperature reaches the next preset gear. Therefore, the display of the water temperature indicator lamp 12 is controlled according to the actual water temperature of the water heater, so that the preset gear at which the current actual water temperature of the water heater is located can be displayed for a user.

The control module may also control the display of the water temperature indicator 12 only according to preset gear positions of the set water temperature. For example, the control module may control the water temperature indicating lamp 12 corresponding to a preset gear of the set water temperature to be turned on or to be turned on constantly according to the preset gear of the set water temperature. Thus, the preset gear of the set water temperature can be displayed to the user by controlling the display of the water temperature indicating lamp 12 according to the preset gear of the set water temperature.

The control module can also control the display of the water temperature indicator lamp 12 according to the actual water temperature of the water heater and the preset gear of the set water temperature. Illustratively, if the actual water temperature does not reach the preset gear of the set water temperature, the water temperature indicator lamp 12 corresponding to the preset gear of the set water temperature is controlled to flash; and if the actual water temperature reaches the preset gear of the set water temperature, controlling the water temperature indicator lamp 12 corresponding to the preset gear of the set water temperature to be normally on. Therefore, the display of the water temperature indicator lamp 12 is controlled according to the actual water temperature of the water heater and the preset gear of the set water temperature, so that whether the current actual water temperature of the water heater reaches the preset gear of the set water temperature or not can be displayed for a user.

The number of the temperature value marks 22 may be four, and the four temperature value marks 22 correspond to a first preset gear, a second preset gear, a third preset gear, and a fourth preset gear one to one. Here, the first temperature value indicator 221 may be "45 ℃", the second temperature value indicator 222 may be "55 ℃", the third temperature value indicator 223 may be "65 ℃", and the fourth temperature value indicator 224 may be "75 ℃". A mark in the word of "temperature" is arranged on one lateral side of the four temperature value marks 22, and is used for prompting that the meaning represented by the plurality of temperature value marks 22 is temperature.

If the actual water temperature does not reach 75 ℃, the control module controls the fourth actual water temperature indicator lamp 134 to flash. If the actual water temperature reaches 75 ℃, the control module controls the fourth actual water temperature indicator lamp 134 to be normally on.

In one embodiment, as shown in fig. 4 to 16, the water temperature indicator 12 includes an actual water temperature indicator 13, the panel 20 is further provided with a plurality of indicator marks 23, the plurality of indicator marks 23 correspond to the plurality of temperature value marks 22 one by one, and the indicator marks 23 are opposite to the corresponding actual water temperature indicator 12.

The plurality of indicator light marks 23 correspond to the plurality of actual water temperature indicator lights 13 one by one, and the position of each indicator light mark 23 is opposite to the position of the corresponding actual water temperature indicator light 13 in the front-rear direction. The plurality of temperature value marks 22 are arranged side by side along the transverse direction of the panel 20, the plurality of temperature value marks 22 comprise a first temperature value mark 221, a second temperature value mark 222, a third temperature value mark 223 and a fourth temperature value mark 224 which are arranged in one-to-one correspondence with a plurality of preset gears, and the position of each temperature value mark 22 and the position of the indicator light mark 23 corresponding to the actual water temperature indicator light 13 are arranged in the same column in the longitudinal direction of the panel 20.
