As disclosed in Japanese Patent Application Laid-Open No. 62-297642, for example, this timer driving device is configured so that the temperature difference between the room temperature and the set temperature T of the day is large or small so that the room temperature almost reaches the set temperature at the set time. Combustion is started before the set time (hereinafter, referred to as the front of the combustion time). In addition, the more recent timer operation device learns the state of the room currently in use by inferring it from the temperature gradient of the rise of room temperature from the start of combustion, and in advance so that the room temperature reaches the set temperature exactly at the set time. Various improvements have been made such as determining the burning time.

[0003]

However, in any of the above-mentioned conventional timer operating devices, combustion is started at the maximum combustion amount from the point where the difference between the room temperature and the set temperature at the start of combustion is large, and the combustion noise is large, so There was the problem of waking up before the time when I was supposed to wake up with the burning sound.

On the other hand, since heating is started at the maximum combustion amount and the combustion amount is gradually reduced, for example, a in FIG.
As is clear from the above, the room temperature rises considerably in the first half of 30 minutes and becomes close to the set temperature 10 minutes before the set time. Therefore, the user is already close to the set temperature while still in the futon, and there is also a problem that it is too warm.

The present invention has been made in view of the above points, and a first object thereof is to start up by weak combustion to reduce noise and improve comfort during timer operation.

A second object is to improve comfort by making room temperature reach a set temperature after a predetermined time even if heating is started by weak combustion and the weak combustion is continued as it is.

A third object is to improve the comfort by gradually increasing the combustion amount during timer operation so that the room temperature becomes the set temperature near the set time so that the user does not feel hot when entering the futon. It is to let.

[0008]

In order to achieve the first object of the present invention, a temperature setting means for setting a desired temperature for equipment, a room temperature detecting means for detecting an indoor temperature, and the temperature setting. Means and the combustion amount determining means for determining the combustion amount based on the signals from the room temperature detecting means, the combustion control means for controlling the combustion by the combustion amount determined by the combustion amount determining means, and the operation is started at the set time. In addition, a timer operation device for sending an instruction to forcibly set the weak combustion amount to the combustion amount determining means is provided.

Further, in order to achieve the second object, the timer operating device sets a timer start switch for instructing an operation start, a current time measuring means for storing and measuring the current time, and a time required for heating. A timer time setting means for setting, a time for the indoor temperature to reach the set temperature due to weak combustion, and a pre-combustion time storage means for storing the room temperature, the set temperature, and the arrival time at that time, and the pre-combustion The arrival time is calculated from the output from the time storage means, the current room temperature and the set temperature, and the advance combustion time learning means for setting the arrival time as the advance time, the current time and the timer time setting means are set. The time comparison means that divides the remaining time from the set time and determines that this remaining time has reached the forward time or less,
The timer combustion switching means for instructing the combustion control means to start the operation based on the result determined by the time comparison means and for sending the instruction to the combustion amount determination means to forcibly set the weak combustion amount. is there.

Further, in order to achieve the third object, the timer operation device starts the operation at a set time, and causes the combustion amount determining means to forcibly set the weak combustion amount at the start of combustion. It is configured to instruct to gradually set the strong combustion amount.

[0011]

With the above structure, the present invention starts heating by weak combustion with a low combustion noise during timer operation.
Significant noise reduction can be achieved.

Further, even if the weak combustion is continued, the room temperature can be set to the set temperature at a predetermined time by calculating the advance time.

Further, by starting heating with a weak combustion amount at first and gradually increasing the combustion amount from the remaining time up to the set time and the degree of reaching the set temperature, the room temperature is set when the user wakes up. Can be close to temperature.

A time setting means, 8 is a current time measuring means 6 and a timer time setting means 7.
The time comparison means 9 compares the time with the time, and determines whether or not the set time has been reached, and 9 indicates the start of combustion to the combustion control means 4 based on the result determined by the time comparison means 8 and a predetermined predetermined value. It is a timer combustion switching means that sends an instruction to forcibly set the weak combustion amount to the combustion amount determination means 3 while performing time combustion.

Next, the operation of the above configuration will be described. First, the power is turned on to the equipment, the current time measuring means 6 sets the current time, and the timer time setting means 7 sets the heating start time. Then, when the timer start switch 5A is turned on, the timer operation is started, and the timer time setting means 7
When the time set in step 4 is reached, the time comparison means 8 detects this, and the timer combustion switching means 9 instructs the combustion control means 4 to start combustion and starts combustion.

At this time, the timer combustion switching means 9 causes the combustion quantity determining means 3 to set the weak combustion quantity in preference to the combustion quantity set based on the outputs from both the room temperature detecting means and the temperature setting means,
This output is sent to the combustion control means 4 for combustion.

Therefore, according to this control device, during the timer operation, the combustion is started with a weak combustion noise, the weak combustion is continued as it is, and the predetermined timer combustion time (1 hour from the normal combustion start) is burned. After that, the combustion is automatically stopped. Therefore, noise during timer operation can be reduced, and comfortable heating can be expected.

Next, a second invention example will be described with reference to FIGS. 2 and 3. The same parts as those of the first invention example will be designated by the same reference numerals and description thereof will be omitted, and only different parts will be described.

First, the timer operating device 5 is constructed so as to start the combustion by estimating the pre-combustion time so that the room temperature becomes the set temperature at the time when heating is required.
The timer time setting means 7 is adapted to set the time when heating is required (the time when the room temperature reaches the set temperature).
The time comparison means 8 compares the time set by the current time counting means 6 with the time set by the timer time setting means 7 in the remaining time comparison section 8A to determine the remaining time, and the time comparison section 8B calculates the remaining time. The time and the advance time from the advance combustion time learning means 11 which will be described later are compared, and if these times match, the timer combustion switching means 9 is made to output the same as the above-mentioned invention example.

Reference numeral 10 denotes a front combustion time storage means, which when the combustion is started by the output from the timer combustion switching means 9,
The room temperature and the set temperature at that time are stored, and the time required until the room temperature reaches the set temperature is also stored by measuring the time until the room temperature reaches the temperature set by the temperature setting means 1. Reference numeral 11 is a forward combustion time learning means, which outputs the forward time from the forward combustion time storage means 10 and the room temperature detection means 2 and the temperature a predetermined time (for example, 2 hours) before the time set by the timer time setting means 7. The temperature output from the setting means 1 is input, and the time for the room temperature to reach the set temperature with weak combustion is estimated from these, and the arrival time is used as the forward time, and the time comparison unit 8B of the time comparison means 8 It is designed to output to.

Next, the operation of the device configured as described above will be described with reference to the flow chart of FIG. When the equipment is powered on and the control section is started and is in a combustion state, timer control is started according to the procedure of the control program shown in the flow chart of FIG.

First, in step 21, it is judged whether or not the timer start switch 5 is turned on. If it is turned on, the process proceeds to step 22. If it is not turned on, the step 3 is performed.
Proceed to 1 to continue the normal combustion process.

In step 22, the time comparison means 8A of the time comparison means 8 determines the difference between the timer time and the current time (hereinafter referred to as the remaining time). In step 23, the forward combustion time learning means 11 estimates the forward combustion time from the present room temperature and the set temperature based on the stored contents of the forward combustion time storage means 10.

At step 24, it is judged whether or not the remaining time calculated from step 22 and step 23 has reached the combustion time or less, and if yes, the routine proceeds to step 25, and if not, the routine proceeds to step 30. In step 25, the timer combustion switching means 9 sends an instruction to the combustion control means 4 to start combustion, and in step 26, the combustion quantity determining means 3 is sent an instruction to forcibly set the weak combustion quantity.

In step 27, it is determined whether the room temperature has risen since the start of combustion and has reached the set temperature. If yes, the process proceeds to step 29. If not, the process proceeds to step 28, and the arrival time measurement is continued. Let In step 29, the pre-combustion time storage means 10 stores the room temperature, the set temperature, and the arrival time when the room temperature reaches the set temperature as data in the memory.

In step 30, the timer combustion switching means 9
Then, an instruction is sent to the combustion control means 4 to stop the combustion. The above steps 21 to 31 are repeated to perform control.

Therefore, according to this configuration, the combustion is weak at the start of the operation, and the weak combustion always continues, so that noise can be suppressed to the minimum, and even if the combustion is weak, the set time is not reached. The room temperature can be set to the set temperature, which improves comfort.

FIG. 4 and FIG. 5 show a third invention example, in which the timer operating device of the present invention starts heating by weak combustion to gradually increase the combustion amount, and the room temperature is kept within a predetermined timer combustion time. It is designed to reach the set temperature.

A third embodiment of the present invention will be described below with reference to FIGS. 4 and 5, and the same parts as those of the first embodiment will be designated by the same reference numerals and detailed description thereof will be omitted and different. The part will be mainly described.

First, the timer time setting means 7 of the timer operating device 5 is set to set the time when heating is required, as in the second invention, and the time comparing means 8 is used for the remaining time comparing section 8.
At A, the current time is compared with the timer time to determine the remaining time, the time of the predetermined time portion 8C in which the forward time is set in advance is compared with the remaining time, and the output is output to the timer combustion switching means 9. It is configured as follows.

Reference numeral 12 is a front combustion amount storage means, which stores the room temperature and the set temperature at the time when the combustion is started by the output from the timer combustion switching means 9, and the time until the room temperature reaches the set temperature. During that time, the consumed combustion amount is measured, and the arrival time and the consumed combustion amount are stored. Thirteen
Is the forward combustion amount learning means, and when combustion is started by the output from the timer combustion switching hand 9, it is set in the predetermined time portion 8C from the output from the forward combustion amount storage means 12 and the current indoor temperature and set temperature. Calculate the consumed combustion amount so that the room temperature reaches the set temperature in the specified time, and maintain the weak combustion at the start of combustion as much as possible when consuming the consumed combustion amount and gradually increase the combustion amount with the passage of time. In addition, the combustion amount determining means 3 is controlled.

Next, the operation of the above configuration will be described with reference to the flowchart of FIG. When the equipment is powered on and the control section is started and is in the combustion state, the timer control is started according to the procedure of the control program shown in the flow chart of FIG.

First, in step 21, it is judged whether the timer start switch 5 is turned on. If it is turned on, the process proceeds to step 22. If it is not turned on, the step 3 is performed.
Proceed to 1 to continue the normal combustion process. In step 22, the remaining time comparing section 8A of the time comparing means 8 obtains the difference between the timer set time and the current time (hereinafter referred to as remaining time).

In step 35, it is determined whether or not the remaining time calculated in step 22 has become less than or equal to a predetermined time, and if yes, the process proceeds to step 25, and if not, the process proceeds to step 30. In step 25, the timer combustion switching means 9 sends an instruction to the combustion control means 4 to start combustion. In step 32, the front combustion amount learning means 13 sends an instruction to the combustion amount determining means 3 to switch the combustion amount according to the learning pattern.

At step 27, it is judged whether the room temperature has risen since the start of combustion and has reached the set temperature. If yes, the process proceeds to step 34, and if not, the process proceeds to step 28 to continue measuring the arrival time. Let In step 34, the front combustion amount storage means 12 stores the room temperature, the set temperature, and the consumed combustion amount and the arrival time at the time when the room temperature reaches the set temperature in the memory as data.

In step 33, the amount of combustion consumed until the room temperature reaches the set temperature is measured. In step 30, the timer combustion switching means 9 sends an instruction to the combustion control means 4 to stop the combustion. Step 21 to Step 35 above
Repeat to control.

Therefore, according to this structure, the combustion amount gradually increases from the degree to which the temperature reaches the set temperature.
As shown in b of FIG. 6, as the time of occurrence approaches, the amount of combustion increases and the room temperature also approaches the set temperature, so that it does not feel hot or the combustion sound is noisy.

In the present embodiment, the pre-reading time has been described in advance, but the pre-reading time may be of the type that is presumed as in the second example of the invention.

Further, each of the above-mentioned embodiments is shown as an example of the present invention, and may have any constitution as long as it achieves the objects and effects of the present invention. Although the microcomputer is used, it may have a circuit configuration capable of performing similar control without using the microcomputer. Similarly, as the learning means, a method for further improving the learning effect by using fuzzy control, neuro-fuzzy control, neuro control or the like may be used.

[0041]

As is apparent from the description of the embodiments, the present invention can start noise combustion at the start of combustion by timer operation, so that noise can be reduced and comfort is improved.

Further, even if the weak combustion is continued, the room temperature can be set to the set temperature at a predetermined time by calculating the advance time,
Along with the noise reduction effect, comfort can be further improved.

Further, by starting heating with a weak combustion amount at first and gradually increasing the combustion amount from the remaining time up to the set time and the degree of reaching the set temperature, the room temperature is set when the user wakes up. The temperature can be kept close to the temperature, and it is possible to wake up without feeling the heat or the burning noise, which further improves comfort.
