Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a futon blower that blows warm air or air at room temperature in a passage formed in the futon itself or a breathable sheet interposed between two futons while the human body enters between the mattress and the comforter About.
[0002]
[Prior art]
A generally known futon dryer is one in which warm air is fed into a breathable sheet interposed between a mattress and a comforter to dry both the mattress and the comforter.
[0003]
As described above, the futon dryer was originally proposed for the purpose of drying the futon, and basically no human enters between the futons during the drying of the futon.
[0004]
That is, the futon dryer simply supplies AC power to the heater and fan during drying, and blows warm air of room temperature + heater temperature on the futon for a time set by a timer.
[0005]
In other words, the futon dryer is a futon dryer dedicated machine that cannot control the temperature of the hot air or set the air volume.
[0006]
However, Japanese Patent No. 3186632 has proposed a futon fan having a configuration slightly similar to that of a futon dryer. This futon blower is completely different from the futon dryer described above in that the human being is placed between the mattress and the comforter, and the desired warm air and air volume are taken in between the mattress and the comforter to prevent the bed slippage of a comfortable sleep or bedridden person. Function is different.
[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 air or cold air between the upper and lower futons that contain humans, but depending on the user's constitution and age, the wind The temperature may be high and make you stuffy. Conversely, the wind temperature may be low and you may not be comfortable.
[0008]
Furthermore, the air volume is also entangled with the air temperature, for example, if the air temperature setting is high, if the air volume is increased, the air temperature will be lower than the desired temperature, and if the air volume is low, the hot air will be very hot. Will come out.
[0009]
For these reasons, 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 commensurate with the set air temperature.
[0010]
[Problems to be solved by the invention]
In addition, the human sensory temperature is quite sensitive, and even if there is a temperature difference of 0.5 degrees, it can be hot or cold, so it is necessary to obtain a subtle temperature depending on various factors. is there.
[0011]
Therefore, if the temperature setting of the air temperature is set at intervals of 0.5 degrees, an ideal sleeping environment can be obtained, but the problem here is that the low temperature setting value of the air temperature setting and the high temperature This is a specific numerical value of the setting value.
[0012]
The high temperature setpoint must be determined based on standard body temperature, and 38 degrees, which is generally slightly higher than body temperature, seems appropriate. However, it is difficult to specify a specific low temperature because there is no standard low temperature setting value.
[0013]
In the present invention, the low temperature set value is set in consideration of the outside temperature in winter and summer, and the user can select any temperature (wind temperature) from the low temperature range to the high temperature range. When set to the lowest position, it eliminates the heat.
[0014]
[Means for Solving the Problems]
The present invention relates to a blower that blows warm air or room temperature air to a futon, wherein the blower includes heating means for converting air into warm air, warm air or room temperature air blowing means, and a set temperature. Operating the up button to raise or the down button to lower the temperature, the temperature setting means to set the air temperature to any temperature from the low temperature range to the high temperature range, and the temperature setting means is set to the lowest position in the low temperature range The blow dedicated means stops the power supply to the heating means and executes the blow means when set to the lowest position by continuous operation of the down button.
[0015]
Further, the apparatus includes an air volume setting unit that arbitrarily sets an air volume by the air blowing unit, and an air volume storage unit that stores the set air volume set by the air volume setting unit. The air volume memorized by is blown.
[0016]

When the heater does not generate heat in the air blowing means (hereinafter referred to as a fan) that discharges from the discharge ports (4) and (4), the intake air at room temperature is blown.
[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 indicating that the operation switch (9) has been operated, and (11) is an air volume adjusting means for changing the air volume by the fan (8) ( (Hereinafter referred to as “air volume button”), it is set to obtain three levels of air volume, “strong wind”, “medium wind”, and “weak wind” by stepping. (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 air temperature discharged 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]

[0020]
FIG. 4 shows a block diagram, and (21) is an air volume setting means for storing one setting state of “strong wind” setting, “medium wind” setting, and “weak wind” setting based on the signal operated by the air volume button (11). , (22) is an air volume control means for controlling the air volume based on the set value of the air volume setting means, and (23) is a "low temperature" setting based on the signals operated by the up button (14) and the down button (15). The temperature setting means for storing the setting state of the “medium temperature” setting and the “high temperature” setting is illustrated in FIG. 4 as if there were only 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, between which can be set at a temperature range of 0.5 degrees . Of course, the classification of each temperature range is a standard, and even if there is a slight change in the temperature range, there is no problem in actual use.
[0021]
(24) is an air flow rate storage means, and when the down button (15) is continuously stepped, the set temperature decreases by 0.5 even in the temperature range divided into the low temperature range, and the lowest position in the low temperature range When the temperature is lowered to 26.5 degrees, the blowing of warm air is stopped and the blowing state with air at room temperature is set, and the temperature indicator (16) is a dedicated blowing means for the blowing mode with “F” display.
[0022]
In other words, the setting of 26.5 degrees is automatically switched to the blowing mode when the display content of the temperature indicator (16) is “F” by the blowing amount storage means (24).
[0023]
(25) is a temperature control means for controlling the air temperature based on the set value of the temperature setting means (21), and (26) is a temperature sensor (not shown) for detecting the air temperature provided in the ventilation path (6). (27) is a timer means for setting the energization time of the fan or heater.
[0024]
Next, the operation will be described. Overlay the mattress and mattress on the mattress as a preparatory work before starting operation. A breathable sheet in which an air passage is formed by sewing is sewn on each futon, and an end (wind intake side) of the air passage is connected to a discharge port.
[0025]
Subsequently, after supplying AC power to the blower (1) and operating the operation switch (9), for example, when setting to increase the air temperature, the up button (14) is stepped and 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 air temperature remains at 38 degrees The fan (8) and the heater (7) are energized in the state set to (S6) and (S7).
[0026]
When the set temperature (Ta) when the temperature setting is completed is a desired temperature X degrees lower than the maximum temperature 38 degrees, normal operation is performed with the wind temperature set at X degrees (S8), (S9) .
[0027]
Further, when setting the air temperature to be lowered after the operation switch (9) is operated, the down button (15) is stepped to lower the set temperature (Tb) by 0.5 degrees (S10) to (S13) When the set temperature (Tb) when the temperature setting is completed is 26.5 degrees which is the lowest position in the low temperature range, the temperature indicator (16) is displayed as “F”, and the blast volume is stored. The air blowing mode is automatically set by means (24) and the air blowing operation is performed (S14) to (S16).
[0028]
In the case of a set temperature that does not display “F” at the time of step (S15) and does not reach the minimum temperature, normal operation is performed with the set temperature (Tb) set at the desired temperature Y degree (S17), ( S18).
[0029]
Although not shown between the futons, humans enter, and the warm air discharged from the air ducts is indirectly applied to the body to sleep or use for heating in winter, but the age of the user The set temperature is changed according to factors such as sex, physiological data such as blood pressure and pulse rate, and outside air temperature.
[0030]
By the way, in the warm air blowing state, when the user feels very hot and wants to take out only the room temperature air immediately, the down button (15) is continuously stepped and the air volume storage means (24) It sets to the lowest position of a low-temperature region, stops energization to a heater (7), and sets it as the ventilation state by room temperature air.
[0031]
The air volume at this time maintains the set air volume 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 blows warm air or room temperature air to the human body in the futon, and provides comfortable sleep and heating according to the desired air temperature and air volume, and also prevents floor rubbing. Can do. In particular, in a configuration in which a desired air temperature is obtained by the temperature adjusting means, when the set temperature is set to the lowest position in the low temperature range by continuously operating the down button, the air blowing means functions and the hot air is automatically For example, when the outside air temperature is high, such as in summer, when the outside air temperature is high, the temperature setting means is operated rapidly when you want to obtain only the air quickly. However, if the continuous operation is performed without being aware of the set temperature for the user's intention, the lowest position is automatically selected, and the ventilation mode is obtained. For example, if it seems that the blowing of room temperature air that occurs when it is set to the lowest position may cause discomfort to the body, the set temperature is raised by operating the same temperature setting means, and a little from the blowing of room temperature air. It can be discharged by changing to warm air with a low temperature.
[0033]
In addition, since the air volume stored by the dedicated air blowing means (air volume storage means) is blown when the room temperature air is blown, a large amount of air volume (high air volume) is suddenly generated when the room temperature air is blown. By generating a pre-set air volume without feeling unsatisfactory due to a small air volume (low air volume), it is possible to set the air volume as desired by the user based on this.
