Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a remote controller for an air conditioner, which is applied to a room air conditioner, a package air conditioner, and the like.

[Conventional technology]

Figure 3 is a diagram showing the liquid crystal display of a conventional air conditioner dayner, and to explain the operation switching, for example, if it is air conditioning, the word "cooling" is displayed, but other dotted line characters are displayed. Characters such as dehumidification, air blowing, ventilation, etc. are not displayed. Also, only the characters shown in solid lines are displayed when switching the intensity and switching the timer.

[Problem that the invention attempts to solve]

The conventional method has the following drawbacks.

For air conditioners. When comparing past and present air conditioners, it is easy to see that they have many different types of functions. In other words, when looking at the operation switching relationship, cooling, dehumidification,
In addition to blowing air and ventilation, there are also devices that have heating, humidifying, and air purifying functions.
If the display and liquid crystal were changed for each mechanism that changes these functions, the number of types of liquid crystal would increase, and the initial investment and parts cost would increase. In addition, in the example of Fig. 3, there are 3 steps for switching the strength.
There are cases with 4 steps and cases with different names for strong, medium and weak. Furthermore, there are different types of timer switching, such as those without a timer function and those that are more complicated than the example shown in FIG. 3 and can set both timer on and off at the same time.

Since you cannot see any characters other than those displayed on the liquid crystal (dotted line characters shown in Figure 3), you will not be able to tell what modes are available during operation, making it difficult to operate unless you are used to it. For example, when you press the operation button next to air conditioning and dehumidification comes on, you don't know what will come out next.

Therefore, the operator has to press the operation button many times, which causes the compressor and blower of the air conditioner to start and stop repeatedly. As is well known, the number of times an air conditioner starts and stops has a significant effect on its durability, as a large current flows during startup, and conventional systems have had problems in this respect.

This invention solves the above-mentioned conventional problems and allows different displays to be displayed on the same liquid crystal display.It also makes it easier to operate the air conditioner, prevents an increase in the number of starts and stops caused by unnecessary operations, and improves durability. An object of the present invention is to provide a remote controller for an air conditioner that can improve the performance of air conditioners.

[Means for solving problems]

A remote controller for an air conditioner according to the present invention is a remote controller for an air conditioner in which a liquid crystal display is provided on the remote controller body and the operating status of the air conditioner is displayed on the liquid crystal display. The set values are displayed in digital numbers using a liquid crystal display, and the various operating modes of the air conditioner are displayed in text around the liquid crystal display 2, and the text indicating the corresponding status is displayed on the liquid crystal display 2. It is characterized by displaying arrows on the liquid crystal. For example, the characters for each mode such as operation switching, strength switching, and timer switching are not displayed on the liquid crystal, but are placed outside the liquid crystal, and arrows, dots, etc. are displayed on the liquid crystal. is displayed, and each mode is displayed according to the movement.

[Effect]

According to the present invention, by using a display outside the liquid crystal display as described above, it is possible to make it easier for the user to understand the content of the next operation, and it is also possible to share the same liquid crystal display for different models. do.

〔Example〕

FIG. 1 is a diagram showing an embodiment of the present invention.
is the remote controller, 2 is the liquid crystal display, 3,
4 and 5 indicate arrows displayed in the liquid crystal display section 2. 6 is a run-stop button, and 7, 8, and 9 are push button switches each having a function displayed on the remote controller 1. 10A and 10B are time set buttons, and 11A and 11B are temperature set buttons.

When the operation switching button 7 is pressed, the operation mode changes sequentially from cooling to dehumidification, blowing, ventilation, and cooling, and the arrow 3 moves to the corresponding position accordingly. Similarly, for the strength switching and timer switching buttons, arrows 4 and 5 move by pressing the button to indicate the mode.

The time at the bottom of the liquid crystal display section 2 is advanced by the time set button 10B, and the time value is returned to its original value by the button 10A.
The time indicates the time indicated in the timer switching mode. In other words, in the example shown in FIG. 1, the timer indicates that the air conditioner will stop at 10:15 AM. The set temperature is changed using the temperature set buttons 11A and 11B. In Figure 1, it is set to 20°C.

FIG. 2 shows an operation switching display section when the present invention is applied to a remote controller 1' of a heat pump type air conditioner. In this example, the heat pump has five modes: cooling, heating, dehumidification, humidification, and ventilation, which is different from the case in Figure 1, but the liquid crystal display 2 only displays arrows 3. You can use the same one. (In Figure 1, arrows can be displayed under ventilation, but they are not actually displayed.) [Effects of the invention] According to the invention, the display of the operation switch, intensity switch, and timer switch can be displayed on the liquid crystal display. Since only the arrows are used instead of letters for each mode, the same LCD can be used even if the mode name is changed. In addition, all modes are displayed on the remote control switch, making it easy to understand the next mode when you press a button, making it easier to operate, and preventing an increase in the number of starts and stops due to unnecessary operations, improving durability. Excellent effects such as measurement can be achieved.

Claims (1)

[Scope of utility model registration request] In a remote controller for an air conditioner where a liquid crystal display is provided on the remote controller body and the operating status of the air conditioner is displayed on the liquid crystal display, the liquid crystal display 2 uses a liquid crystal to display set values in digital numbers. At the same time, various operating modes of the air conditioner are displayed in text around the liquid crystal display section 2, and text indicating the corresponding state is displayed by arrows displayed on the liquid crystal of the liquid crystal display section 2.
