[Problem that the idea aims to solve]

In the conventional technology, when the timer operation starts, the room temperature reaches the set temperature at the set time. The timer is corrected and operates on a timer, but the air conditioner is unable to warm up the air conditioner by capturing the ever-changing room temperature. The relationship between cooling capacity and indoor environment is learned and memorized, and when the timer is running, the room temperature and learning results are For example, in order to update the timer operation start time every moment while comparing and calculating the When processing on a computer, a memory that can be read and written at any time (R AM) The problem was that it required a large capacity device, making it an expensive device.

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

[0009] Figure 1 is a block diagram of an air conditioner timer operation control device showing one embodiment of the present invention. be.

0010 In the figure, 1 is a room temperature detection means that measures the current room temperature, and 2 is a temperature sensor that sets the room temperature. temperature setting means; 3 is a timer time setting means for causing the heating and cooling means 7 to be operated on a timer; Step 4 is a time clock means for measuring the current time, and step 5 is a means for keeping the room temperature at a predetermined level from the start of timer operation. arrival time measuring means for measuring the time until the temperature is reached; 6 is a correction means to be described later; , for example, a computer. 7 is a heating/cooling hand that heats and cools the air-conditioned room. Stage 8 is a control means for controlling the heating and cooling means 7. The above-mentioned room temperature detection means 1. Temperature setting means 2, timer time setting means 3, time measuring means 4, reaching time measuring hand The stages 5 are each connected in parallel to a correction means 6, which in turn is connected via a control means 8. and is connected to heating and cooling means 7.

[0011] Next, we will explain the timer operation of an air conditioner timer operation control device which is an embodiment of the present invention. The operation will be explained according to the flowchart shown in FIG.

0012 Now, the timer operation is set at the time set by the timer time setting means 3 and temperature setting means 2. Assume that the set temperature is set.

[0013] First, in step 101, check whether a predetermined time (for example, one hour) has passed before the set time. If not, repeat step 101 until the predetermined time has passed. If so, in step 102, the room temperature detection means 1 measures the current room temperature.

[0014] In step 103, the correction means 6 stores the temperature difference between the current room temperature and the set temperature. If the current temperature difference is large, the first compensation is applied according to the difference. Set the hour on the positive side, and if the previous temperature difference is large, set it on the negative side according to the difference. If there is little difference in degree, set it to 0.

[0015] Further, the correction means 6 adjusts the stored temperature gradient to the internally set temperature gradient. If it is larger than the standard value, adjust the second correction time to the negative side according to the size of the temperature gradient. If it is small, set it to the positive side, and if it is close to the standard value, set it to 0. Further, the correction means 6 The first correction time and the second correction time are combined to obtain the correction time and are stored. The preceding time for the timer setting time is obtained by adding the above correction time to the previous arrival time. Then, set (correct) the current timer operation start time.

[0016] In step 104, the correction means 6 determines whether the timer operation start time has arrived. If not yet, repeat step 104, and if the timer operation time has come, perform compensation. The positive means 6 inputs the signal to the control means 8, and in step 105, the control means 8 controls the heating and cooling operation. Start stage 7 operation. In step 106, the correction means 6 adjusts Measure the temperature gradient, which is the change in room temperature. Step 107 corresponds to the set temperature The correction means 6 determines whether the predetermined temperature has been reached, and if the predetermined temperature has not been reached, , step 107 is repeated, and if the arrival time is reached, the arrival time is measured in step 108. In step 109, the correction means 6 calculates the temperature gradient, arrival time, and timer setting time. Update the temperature difference between the current room temperature and the set temperature when the timer operation start time is set a predetermined time ago. The new timer is stored and prepared for setting (correcting) the start time of the next timer operation.

[0017] Here, as another example, the temperature difference to be stored is set a predetermined time before the timer setting time. The temperature difference between the room temperature when setting the timer start time and the set temperature when measuring the arrival time. It's okay. In this case, even if you change the set temperature after starting timer operation, the change will not occur. The temperature difference and arrival time are based on the set temperature, so even if you change the set temperature midway, the next correction is performed correctly.

[0018] In addition, since the set temperature is usually almost the same, it is important to note that the previous and current settings Temperature difference between the room temperature and the set temperature when the timer operation start time is set a predetermined time before the set time may simply be each current room temperature. In this case, read without finding the temperature difference. However, if you use room temperature as is, you can simplify the microcontroller processing.

[0019] When you use this type of timer operation, the set time is determined by taking into account temperature differences, room size, etc. Efficient timer operation control is possible to reach the set temperature exactly.

[0020] In addition, the data stored for use in correcting the timer operation start time is (1) timer operation start time. (2) the time from the start of operation until the set temperature is reached; and (2) the time from the start of operation to the set temperature. (3) A certain temperature gradient from the timer setting time. The room temperature detected by the room temperature detection means when setting the timer operation start time before the time and the set temperature Only three pieces of data are required: the temperature difference between It is possible to realize an inexpensive timer operation control device for air conditioners.

[0021]

[Effect of the idea]

As explained above, according to the present invention, a predetermined period of time before the timer operation setting time When setting the timer operation start time, the correction means is set to correct the timer operation start time. Temperature detection means, temperature setting means, timer time setting means, time measuring means and arrival time meter Since the time means are connected in parallel, the following effects can be obtained.

[0022] (1) Timer operation at an appropriate time depending on the day's room temperature and the size of the room being used. In order to start, the set temperature is reached at the set time and the timer operation is efficient and comfortable. realizable.

[0023] (2) The data stored for use in correcting the timer operation start time is as described in (a) above. Only three pieces of data are required: arrival time (b) temperature gradient (c) temperature difference, and it is controlled by a microcomputer etc. In this case, an inexpensive device with a small RAM capacity could be realized.
