Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a futon blower that blows warm air or room temperature air into a passage formed in a futon itself or a breathable sheet interposed between two futons with a human body inserted between a futon and a futon. .
[0002]
[Prior art]
A generally known futon dryer is one in which warm air is sent to a breathable sheet interposed between the mattress and the comforter to dry both the mattress and the comforter.
[0003]
The futon dryer is originally proposed for drying the futon as described above, and basically, no human enters between the futons while the futon is drying.
[0004]
That is, the futon dryer simply supplies AC power to the heater and the fan and blows the futon with hot air of room temperature + heater temperature for a time set by a timer during drying.
[0005]
In other words, the futon drying machine is a futon drying machine that cannot control the hot air temperature or set the air volume.
[0006]
However, a futon blower having a configuration slightly similar to the futon dryer has been proposed in Japanese Patent No. 3186632. This is completely different from the futon dryer in that it takes in the desired warm air and air volume with a human being between the mattress and the comforter to prevent comfortable sleeping and bedridden bedridden people.
[0007]
[Problems to be solved by the invention]
However, the above-mentioned prior art is effective in creating a comfortable sleeping environment by sending warm or cold air to the futon where humans are contained, but the wind temperature is high depending on the constitution and age of the user. You may feel suffocated, and conversely, the wind temperature may be too low to provide comfort.
[0008]
Furthermore, from the entanglement with the air temperature in the air volume, for example, when the air temperature is set to a high temperature side, when the air volume is increased, the air temperature is lower than the desired temperature, and when the air volume is small, a considerably high temperature hot air is generated. Will come out.
[0009]
For such a reason, it is necessary to set the air temperature and the air volume in association with each other, and it is desirable to obtain an air volume corresponding to the set air temperature.
[0010]
[Problems to be solved by the invention]
In addition, the human perceived temperature is quite sensitive, and even if there is a temperature difference of 0.5 degrees, it may be hot or cold, so it is necessary to obtain a delicate temperature according to various factors. is there.
[0011]
Therefore, if the temperature setting of the wind temperature is set at 0.5 degree intervals, an ideal sleeping environment can be obtained, but the problem here is that the low temperature setting value and the high temperature This is a specific numerical value of the set value.
[0012]
The high temperature setting must be determined based on standard body temperature, and 38 degrees, which is generally slightly higher than body temperature, seems appropriate. However, the low-temperature set value has no reference and it is difficult to specify a specific temperature.
[0013]
According to the present invention, the low temperature setting value is set in consideration of the outside air temperature in winter or summer, and the user can select an arbitrary temperature (wind temperature) from a low temperature region to a high temperature region. When set to the lowest position, it eliminates the heat.
[0014]
[Means for Solving the Problems]
The present invention relates to a blower for blowing warm air or room temperature air to a futon, wherein the blower includes a heating means for converting air into warm air, a warm air or room temperature air blowing means, and a wind blown by operation. Temperature setting means for setting a temperature from a low temperature range to an arbitrary temperature in a high temperature range, and the temperature setting means includes a blower only means set at a lowermost position of the low temperature range, and the blower only means comprises a temperature setting means. When the operation is set to the lowest position, the power supply to the heating means is stopped and the blowing means is executed.
[0015]
An air volume setting unit for arbitrarily setting an air volume by the air blowing unit; and an air volume storing unit for storing a set air volume set by the air volume setting unit. Is to send the stored air volume.

In the case where there is no heat generated by a heater, the air is blown at room temperature by a blowing means (hereinafter referred to as a fan) which discharges the air from the discharge ports (4) and (4).
[0018]
Next, the remote controller shown in FIG. 3 will be described. (9) is an operation switch for starting operation, (10) is an operation indicator for displaying that the operation switch (9) has been operated, and (11) is an air volume adjusting means (10) for changing the air volume by the fan (8). The button is set so that three steps of "strong wind", "medium wind", and "weak wind" can be obtained by step pressing. (12) (12) (12) is an air volume indicator for displaying the air volume set by the air volume button (11), and (13) is a temperature adjusting means for setting the temperature of the air blown from the discharge port (4). And an up button (14) for increasing the set temperature and a down button (15) for decreasing the set temperature.
[0019]
(16) is a temperature display comprising a 7-segment display element for displaying the temperature set by the up button (14) or the down button (15), which is displayed in units of 0.5 degrees, and is provided in the low temperature range. "F" is displayed at the lowest position. (17) is a room temperature sensor provided for detecting the room temperature and maintaining the temperature of the air in the ventilation path (6) at a set temperature, (18) is a quick warm button for rapidly increasing the wind temperature, and (19) is a speed button. A display indicating the warm setting state, and (20) is a futon drying button for automatically setting a wind temperature suitable for drying the futon.
[0020]
FIG. 4 shows a block diagram, and (21) an air volume setting means for storing one setting state of “strong wind” setting, “medium wind” setting, and “weak wind” setting based on a signal operated by the air volume button (11). , (22) is an air volume control unit for controlling the air volume based on the set value of the air volume setting unit, and (23) is a “low temperature” setting based on a signal operated by the up button (14) and the down button (15). , The "medium temperature" setting and the "high temperature" setting are stored in the temperature setting means. In FIG. 4, the set temperature is plotted as if there were only the three positions as described above. 26.5-30.5 degrees, 31.0-35.0 degrees in the middle temperature range, 35.5-38.0 degrees in the high temperature range, and the temperature can be set in 0.5 degree increments. . Of course, the classification of each temperature range is only a guide, and there is no actual use problem even if the temperature range slightly changes.
[0021]
(24) is an air flow amount storage means. When the down button (15) is continuously step-pressed, the set temperature is reduced by 0.5 even in the temperature region divided into the low temperature region, and the lowest position of the low temperature region is set. When the temperature drops to 26.5 degrees, the blowing of the warm air is stopped and the air is blown by the air at room temperature, and the temperature indicator (16) is a means exclusively for blowing, which is in a blowing mode of displaying "F".
[0022]
In other words, in the setting of 26.5 degrees, the display content of the temperature indicator (16) is automatically switched to the air blowing mode when the display content of the temperature indicator (16) is "F" by the air blowing amount storage means (24).
[0023]

[0025]
Subsequently, after supplying AC power to the blower (1) and operating the operation switch (9), for example, in the case of setting to increase the wind temperature, the up button (14) is step-pressed to set the set temperature ( Ta) is increased by 0.5 degrees (S1) to (S4), and when the set temperature (Ta) at the end of the temperature setting is 38 degrees at the highest position in the high temperature range, the wind temperature is 38 degrees as it is. Then, the fan (8) and the heater (7) are energized to perform the normal operation (S6), (S7).
[0026]
When the set temperature (Ta) at the end of the temperature setting is the desired temperature X degrees lower than the maximum temperature 38 degrees, the normal operation is performed with the air temperature set at X degrees (S8), (S9). .
[0027]
When setting to lower the wind temperature after the operation of the operation switch (9) is performed, the down button (15) is step-pressed to lower the set temperature (Tb) by 0.5 degrees (S10) to (S10). (S13) If the set temperature (Tb) at the end of the temperature setting is 26.5 degrees, which is the lowest position in the low temperature range, the temperature display (16) indicates "F" and the air volume is stored. The air blowing mode is automatically set by the means (24) and the air blowing operation is performed (S14) to (S16).
[0028]
If the set temperature does not reach the minimum temperature without displaying "F" at the time of step (S15), the normal operation is performed with the set temperature (Tb) set at the desired temperature Y degrees (S17), S18).
[0029]
Although not shown, humans enter between the futons, and indirectly apply warm air discharged from the air passages (28) and (29) to the body to use for sleeping or heating in winter. However, the set temperature is changed according to factors such as the age of the user, gender, physiological data such as blood pressure and pulse rate, and outside temperature.
[0030]
By the way, when the user feels very hot and wants to immediately take out only the air at room temperature in the hot air blowing state, the down button (15) is continuously step-pressed and the air volume storage means (24) is used. The heater (7) is set to the lowest position in the low temperature range to stop energizing the heater (7), and is set to be in a state of being blown by room temperature air.
[0031]
The air volume at this time maintains the air volume set at the time of hot air extraction set by the air volume storage means (24).
[0032]
【The invention's effect】
As described above, the present invention is to send warm air or room temperature air to a human body entering a futon, and to obtain comfortable sleep and heating with a desired air temperature and air volume, and to prevent floor rubbing. Can be. In particular, in a configuration in which a desired air temperature is obtained by the temperature adjusting means, only when the set temperature is set to the lowest position in the low-temperature region, the air-only means functions to automatically stop the generation of the hot air. For example, when the outside temperature is low, such as in summer, when the temperature is set to the low temperature side, the operation by the temperature setting means is performed rapidly when it is desired to obtain only the air in a hurry, but the user's intention By selecting the lowermost position with, air can be obtained. This means that, for example, if the airflow of room temperature air generated at the time of setting at the lowest position is considered to cause discomfort to the body, the set temperature is increased by operating the same temperature setting means and the airflow of room temperature air is slightly increased. Discharge can be performed by changing to low-temperature hot air.
[0033]
Further, when the room temperature air is blown, since the air volume stored by the air blowing dedicated means (air volume storage means) is blown, a large amount of air (high air volume) is suddenly generated when the room temperature air is blown, or the user is surprised. By generating a preset air volume without feeling unsatisfactory due to a small air volume (low air volume), it is possible to set the air volume to a user's favorite air volume based on this.
