[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner which starts operation before a set time of an on-timer to set a room temperature to a target set temperature at the time of the on-timer.

[0002]

2. Description of the Related Art Conventionally, an air conditioner that starts operation before a set time of an on-timer and controls the operation so that the room temperature reaches a target set temperature at the time of the on-timer is set. is there. In this air conditioner, an experiment is performed using a model that determines the size of the room, the heat insulation, etc., and the room temperature, the outside air temperature, and the target set temperature are adjusted so that the indoor temperature becomes the target set temperature at the set time of the input timer. On the basis of,
The operation time from the start of operation to the set time of the on timer is determined.

[0003]

However, in the above-mentioned air conditioners, the room temperature does not reach the target set temperature even at the set time of the on-timer because the actual room size and the heat insulation are various. However, there is a disadvantage that the comfort is impaired, and conversely, the room temperature reaches the target set temperature before the set time of the ON timer, and the power consumption increases.

An object of the present invention is to provide an air conditioner capable of obtaining an optimum operation time from the start of operation to the set time of an on-timer.

[0005]

In order to achieve the above object, the air conditioner according to the first aspect of the present invention operates from the start of operation to the ON timer set time so that the room temperature reaches the target set temperature at the ON timer set time. Calculating the time, and in the air conditioner performing the operation, correcting the operation time based on the result of determining the temperature difference between the indoor temperature at the previous ON timer set time and the previous target set temperature. And

According to the air conditioner of the first aspect, for example, based on the outside air temperature, the indoor temperature, and the target set temperature,
When calculating the operation time from the start of operation to the ON timer set time, the result of determining the temperature difference between the room temperature at the previous ON timer set time and the previous target set temperature is reflected in the operation time. For example, in the cooling operation, if the room temperature is higher than the target set temperature at the previous ON timer set time,
If the room temperature is lower than the target set temperature at the previous set time of the on timer, the operation time is corrected to be longer, and the operation time is corrected to be shorter. To be obtained. Therefore, the room temperature does not reach the target set temperature at the ON timer set time, or conversely, the room temperature does not reach the target set temperature before the ON timer set time. Accordingly, it is possible to obtain an optimal operation time from the start of operation to the set time of the ON timer.

[0007] The air conditioner according to the second aspect of the present invention is the first aspect of the invention.
In the air conditioner, during the cooling operation, when the indoor temperature at the previous set time of the ON timer is higher than the previous target set temperature, the above operation time is corrected to be longer, while the indoor temperature at the previous set time of the ON timer is corrected. When the temperature is lower than the previous target set temperature, the operation time is corrected to be shorter.

According to the air conditioner of the second aspect, when the room temperature at the previous set time of the on-timer is higher than the previous target set temperature, the cooling time is not enough, so that the operation time becomes longer. Correction is performed so that the room temperature becomes the target set temperature at the set time of the on-timer, thereby improving comfort. When the indoor temperature at the previous set time of the on-timer is lower than the previous target set temperature, the room temperature has already reached the target set temperature before the set time of the on-timer. Then, at the set time of the ON timer, the room temperature is set to the target set temperature, and the power consumption can be reduced.

[0009] The air conditioner according to the third aspect is characterized by the first aspect.

Is characterized in that the above operation time is corrected to be shorter when the temperature is higher than the previous target set temperature.

According to the air conditioner of the third aspect, when the room temperature at the previous set time of the on-timer is lower than the previous target set temperature, the heating time is not enough, so that the operating time becomes longer. Correction is performed so that the room temperature becomes the target set temperature at the set time of the on-timer, thereby improving comfort. If the room temperature at the previous ON timer set time is higher than the previous target set temperature, the room temperature has already reached the target set temperature before the ON timer set time. Then, at the set time of the ON timer, the room temperature is set to the target set temperature, and the power consumption can be reduced.

The air conditioner according to the fourth aspect of the present invention calculates the operation time from the start of operation to the ON timer set time so that the room temperature becomes the target set temperature at the ON timer set time, and operates the air conditioner. In the machine, on-timer setting means for setting the on-timer set time and the target set temperature, based on the room temperature, the outside air temperature and the target set temperature,
An operation time calculating means for calculating an operation time from the start of operation to the on-timer setting time, and an operation time calculated by the on-timer setting time set by the on-timer setting means and the operation time calculated by the operation time calculating means. Operating start time calculating means for calculating an operating start time, operating control means for starting operation at the operating start time calculated by the operating start time calculating means, and At the entry timer set time, comprises an indoor temperature determining means for determining a temperature difference between the room temperature at that time and the target set temperature, the operating time calculating means,
Based on the result of the indoor temperature determining means determining a temperature difference between the indoor temperature at the previous set time of the on-timer and the previous target set temperature, the operation time is set so that the target set temperature is obtained at the set time of the on-timer. It is characterized by having a correction unit for correcting.

According to the air conditioner of the fourth aspect, the on-timer set time and the target set temperature are set by the on-timer setting means, and the operation is started based on the outside air temperature, the room temperature, and the target set temperature. The operation time from the time to the set time of the on-timer is calculated by the operation time calculation means. At this time, the correction unit of the operation time calculation unit reflects the result of the determination of the temperature difference between the indoor temperature at the previous set time and the previous target set temperature by the indoor temperature determination unit in the operation time. For example, in the cooling operation, when the indoor temperature is higher than the target set temperature at the previous set time, the operation time is corrected to be longer, and when the indoor temperature is lower than the target set temperature at the previous ON timer set time. Is to correct the operation time so that the operation time is shortened, and this operation is repeated for each operation of the ON timer, so that an appropriate operation time can be obtained.
Then, the operation start time is calculated by the operation start time calculation means based on the ON timer set time set by the ON timer setting means and the operation time calculated by the operation time calculation means. After the operation is started by the operation control means at the operation start time calculated by the operation start time calculation means, at the on-timer set time, the temperature difference between the room temperature at that time and the target set temperature is determined by the indoor temperature determination means. , And as described above, the result of the determination is reflected in the operation time calculated at the next operation of the ON timer. Therefore, the room temperature does not reach the target set temperature at the ON timer set time, or conversely, the room temperature does not reach the target set temperature before the ON timer set time. Accordingly, it is possible to obtain an optimal operation time from the start of operation to the set time of the ON timer.

Department. The on-timer setting unit 1 automatically sets the target set temperature in the automatic operation mode and manually sets the target set temperature in the manual operation mode.

In the air conditioner having the above configuration, for example,
The home return time is set as the on-timer set time so that the room is comfortably air-conditioned when returning home, and the desired indoor temperature at that return time is set as the target set temperature.
Based on the on-timer set time and the target set temperature thus set, the control device 10 obtains an operation time required for the room temperature to reach the target set temperature at the on-timer set time, and calculates the operation time from the on-timer set time. The operation is started at the operation start time before the time, and the cooling operation or the heating operation is controlled until the ON timer set time.

FIG. 2 is a flowchart for explaining the operation of the control device 10 of the air conditioner at the time of cooling operation.

The operation of the on timer during the cooling operation of the control device 10 for the air conditioner will be described below with reference to the flowchart of FIG.

First, when the process starts, step S
It is determined at 1 whether or not the on-timer is being set, and if it is determined that the on-timer is being set, the process proceeds to step S2, where it is determined whether or not the operation time calculation time (for example, 1 hour and 30 minutes before the on-timer set time) is present. Determine. If it is determined in step S2 that the current time is the operation time calculation time, the process proceeds to step S3. If it is determined that the current time is not the operation time calculation time, step S2 is repeated.

Next, in step S3, the operation time calculation section 2 calculates the operation time T by the following [Equation 1].

Operation time T = (outside air temperature × α + β) × (indoor temperature−target set temperature) × γA (Equation 1) where α and β are constants, γA is a correction coefficient, and γA The initial value is 1.0. Further, an operation start time is calculated by an operation start time calculation unit 3 based on the ON timer set time set by the ON timer setting unit 1 and the operation time calculated by the operation time calculation unit 2.

Next, proceeding to step S4, the operation start time calculation section 3 determines whether or not the current time is the operation start time. If it is determined that the current time is the operation start time, the flow proceeds to step S5, where the operation is controlled by the operation control section 4. It turns on and it progresses to step S6. On the other hand, if it is determined in step S4 that it is not the operation start time,
Step S4 is repeated.

Next, in step S6, it is determined whether or not the set time of the on-timer has come. If it is determined that the set time of the on-timer has come, the process proceeds to step S7. Step S6 is repeated.

Next, at step S7, it is determined whether or not the room temperature is equal to the target set temperature at the set time of the on-timer. If it is determined that the room temperature is equal to the target set temperature, the process proceeds to step S9, where γ is set to 1 .0, step S12
Proceed to. On the other hand, if it is determined that the room temperature is not equal to the target set temperature, the process proceeds to step S8, and it is determined whether the room temperature is lower than the target set temperature. And step S
When it is determined in step 8 that the room temperature is lower than the target set temperature,
Proceeding to step S10, γ is set to 0.9 and step S10
Proceed to 12. On the other hand, if it is determined in step S8 that the room temperature is equal to or higher than the target set temperature, the process proceeds to step S11,
γ is set to 1.1, and the process proceeds to step S12.

Next, at step S12, a correction coefficient γA (= previous γA × γ) is calculated. Then, the process proceeds to step S13 to perform the normal operation, returns to step S1, and thereafter performs the same processing.

FIG. 3 is a diagram for explaining the operation of the input timer of the control device 10 for the air conditioner. As shown in FIG.
For example, when the ON timer is set (setting of the ON timer setting time) at 11:00 PM and the ON timer setting time is AM6: 00, the operation time calculation time of AM4: 30 is 1 hour and 30 minutes before AM6: 00. Then, the operation time T (= 40 minutes) is calculated based on the room temperature at that time and the set target set temperature, and the operation start time is set to AM5: 20 (40 minutes before AM6: 00). Then, the operation is turned on at 5:00:20 of the operation start time, and after 6:00 of the ON timer set time,
Perform normal operation. AM 6:00 of the above set time of the input timer
Next, the temperature difference between the indoor temperature and the target set temperature is determined by the indoor temperature determining unit 5. Then, at the time of the next operation of the ON timer, the operation time calculation section 2 calculates the operation time T corrected based on the judgment result (correction coefficient γA) of the indoor temperature judgment section 5.

In this way, the correction unit 2a of the operation time calculation unit 2 calculates the operation time for each operation of the input timer based on the determination result of the temperature difference between the room temperature and the target set temperature at the previous input timer set time. Correct to gradually obtain the optimal operation time. Therefore, the room temperature does not reach the target set temperature at the set time of the ON timer, or the room temperature does not reach the target set temperature before the set time of the ON timer. Thus, it is possible to obtain an optimal operation time from the start of operation to the set time of the on-timer.

When the room temperature at the previous set time of the on-timer is higher than the previous target set temperature, the cooling time is not enough, and the correcting unit 2a of the operating time calculating unit 2 increases the operating time. To make the room temperature equal to the target set temperature at the set time of the on-timer, thereby improving comfort. When the indoor temperature at the previous set time of the on-timer is lower than the previous target set temperature, the cooling time is short and the indoor temperature has already reached the target set temperature before the set time of the on-timer. The correction unit 2a of the unit 2 corrects the operation time to be short, so that the room temperature becomes exactly the target set temperature at the set time of the ON timer, and the power consumption can be reduced.

In the above embodiment, the operation time calculation time is one hour and 30 minutes before the on-timer set time, but the operation time calculation time may be an appropriate time before the on-timer set time.

In the above embodiment, the operation of the ON timer in the cooling operation has been described. However, the present invention may be applied to the heating operation. In this case, steps S10 and S10 in the flowchart of FIG. By replacing S11, if the room temperature is lower than the target set temperature, the operation time is corrected so as to increase the operation time, while if the room temperature is higher than the target set temperature, the operation time is shortened. To correct the operation time.

In the above embodiment, the operating time calculating section 2 as the operating time calculating means calculates the operating time T according to [Equation 1], but calculates the operating time from the start of operation to the set time of the on-timer. The expression to be performed is not limited to this.
