Abstract

PURPOSE:To raise the pleasantness in space heating that is provided with an upper limit value selection means capable of selecting the upper limit value of calorific value by providing an upper limit value changing means that changes a set upper limit value by receiving signal from a time counting means. CONSTITUTION:When an upper limit value selection means 6 selects an upper limit value which matches the room a user uses, and if this upper limit value is set as the upper limit value of calorific value by an upper limit value setting means 8, a space heater 10 is made to generate heat at the set upper limit value by calorific value controlling means 9 unitl the room temperature comes near the set temperature. And when the room temperature comes near to the set temperature, the calorific value is gradully lowered and the room temperature is let to converge to the set temperature. And at this time the respective outputs of a temperature setting means 1 and room temperature sensing means 2 are compared by a comparison means 3, and the time at which both values coincide is measured by a timer 4. And if, after a specified time has passed, the room temperature has not reached the set temperature, the upper limit value of an upper limit value setting means 8 is upgraded by one rank by an upper limit value changing means 7.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The contents of the present invention will be explained in detail below with reference to the drawings.

In FIG. 1, 1 is a room temperature detection means for detecting the room temperature, and 2 is a temperature setting means for setting the room temperature for heating.The room temperature detection means 1 and the temperature setting means 2 are connected to a comparison means 3. ing. Comparison means 3 is room temperature detection means 1
The room temperature signal from the temperature setting means 2 and the set temperature signal from the temperature setting means 2 are compared. 4 is a timing means for timing a predetermined time; 5
6 is an operation continuation means for extending or continuing the operation, and 6 is an upper limit value selection means, through which the user selects the upper limit value of the calorific value step by step according to the size of the room to be used, etc. The timing means 4 includes a comparison means 3, an operation continuation means 5, and an upper limit value selection means 6.
A predetermined time is measured by receiving the signal. Reference numeral 7 denotes an upper limit value changing means for changing the upper limit value of the calorific value, and changes the upper limit value upon receiving signals from the timer means 4 and operation continuation instruction means 5. Reference numeral 8 denotes an upper limit value setting means, which sets the upper limit value selected by the upper limit value setting means 7 or the value changed by the operation continuation instruction means 5 as the upper limit value of the calorific value. Reference numeral 9 denotes a calorific value control means, which controls the calorific value based on the signal from the comparison means, with the upper limit value set by the upper limit value setting means 8 as the maximum calorific value.

FIG. 2 shows the relationship between the selection of ranks and the selected upper limit value. For example, the range of heat generation amount that can be selected is set to four ranks, and the number of control steps for heat generation amount from the minimum to the maximum is set to 15 levels. That is. The upper limit of the heat value for each selected rank is the rated level 15 for the selected rank of 12 tatami mats or above, and the lower level 1 for the selected rank of 8 tatami mats.
2. For 6 tatami mats, the level is even lower, 9, and for 4.5 tatami mats, it is level 7. In addition, the minimum calorific value is level 1
It becomes. Here, the number of heat generation control stages according to the selected rank remains unchanged at 15 levels, and each level is used differently for each selected rank.

[0013] When driving for the first time, the selection rank is preset to the maximum of 12 tatami mats or more.
It was changed downward sequentially to tatami, 6 tatami, 4.5 tatami, and then 12 tatami again.
Repeat the return to tatami or above.

Next, the procedure for controlling the heater will be explained according to the flowchart shown in FIG.

First, in step 101, the user selects an upper limit value suitable for the room used, and the upper limit value set in the upper limit value setting means 8 is determined by the timer means 4 or the operation continuation instruction means 5.
Assuming that the temperature is not changed by , heat is generated at the upper limit value set in the upper limit value setting means 8 by the upper limit value selection means 6 until the temperature reaches around the set temperature, and when the room temperature reaches around the set temperature, the amount of heat generation is gradually lowered. The heating value is increased or decreased within the range of 1 to the upper limit value so that the room temperature reaches the set temperature. As a result, the heat generation control means 9 controls the heating to be quiet and optimal for the room without causing discomfort due to large heat generation or large air volume in normal use.

In step 102, the comparison means 3 compares the room temperature detected by the room temperature detection means 2 and the set temperature of the temperature setting means,
The room temperature is controlled, and if the room temperature is the same as or higher than the set temperature, the time measurement by the timer 4 is stopped in step 103, and the process proceeds to step 11.
Go to 1. Therefore, for example, if the room being used is expanded from one room to two, and the room temperature cannot be maintained at the set temperature with the upper limit currently set in the upper limit value setting means 7, and the room temperature is lower than the set temperature, step 104 is performed. It is determined whether or not time is being measured, and if the room temperature is continuously lower than the set temperature and time is being measured, the process proceeds to step 106, and if time is not being measured, new time measurement is started in step 105.

In step 106, it is determined whether or not the time measurement has ended. If the time measurement is still in progress and the time measurement has not ended, step 11
1, and if the room temperature continues to be lower than the set temperature for a predetermined period of time and the time measurement ends, it is determined in step 107 whether or not the current upper limit value is the rated level 15. If the level is 15, the upper limit value cannot be increased, so the time measurement is stopped in step 108 and the process proceeds to step 111. If the level is less than 15, in step 109 the upper limit value changing means 7 increases the upper limit value of the upper limit value setting means 8 by one rank in response to the signal from the timer means 4, and in step 110 the timer is stopped and a new timer is started. is started, and the process proceeds to step 111. The calorific value control means 9 controls the calorific value within a range up to the upper limit value which is one rank higher, and controls the room temperature to quickly reach the set temperature. Moreover, by repeating this process, the amount of heat generated can be increased to the rated value. In step 111,
If the signal from the operation continuation instruction means 5 is received and the operation is continued or extended during operation, step 112 is performed.
The upper limit value set in the upper limit value setting means 8 is the upper limit value of the minimum rank of the calorific value ranks that can be selected by the upper limit value selection means 6 including the current calorific value level or the calorific value selected by the upper limit value selection means 6. Change the higher limit of the rank upper limit values as the upper limit value, and once the upper limit value is changed and the room temperature reaches the set temperature, if the situation is such that it can be sufficiently controlled even with a low calorific value, the upper limit value is changed. Correct the value downward. If there is no need to continue driving, continue with step 1.
Proceed to step 13. Here, even if the operation is not continued, the upper limit value may be revised downward when a situation in which sufficient control can be achieved with a low calorific value has elapsed for a predetermined period of time or more.

In step 113, a signal is received from the upper limit selection means 6, and if the selection is changed during operation, in step 114, the upper limit value setting means 8 is changed to the upper limit newly selected by the upper limit selection means 6. The upper limit value of is changed, the time measurement is stopped, and a new time measurement is started, and the process proceeds to step 115. If there is no change in the selection, the process directly proceeds to step 115.

In step 115, it is determined whether or not to stop the operation. If the operation is to be stopped, in step 116, the upper limit value of the upper limit value setting means 8 is changed to the upper limit value selected by the upper limit value selection means 6. Stop the equipment and prepare for the next operation. If the operation is not stopped, the process returns to step 101 and the operation is repeated.

[0020]

[Effects of the Invention] As explained above, according to the heater of the present invention, it is possible to select the upper limit of the amount of heat generated according to the size of the room in which it is used, and it is possible to not only perform heating without waste, but also to The room temperature may not reach or no longer reach the set temperature, such as if you have chosen the wrong upper limit for the quantity, if you have significantly changed the size of the room you are using, or if the outdoor temperature has become very cold. Since the upper limit value of the calorific value is changed every time a predetermined period of time elapses, the room temperature can be kept at the set temperature, and comfortable heating can be performed.

[0021] In addition, when the room temperature is controlled with the upper limit value changed, and the room temperature is stable within the changed upper limit value with a margin, etc., operation may be continued or the room temperature may be kept for a predetermined period of time or longer. If you continue, the upper limit value will be corrected to be closer to the selected upper limit value, and from then on, the upper limit value will be adjusted to match the room in response to fluctuations in room temperature, resulting in efficient, quiet and smooth heating. can be done.
