Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a temperature control device used for bedding, etc. for the purpose of heating and heat retention, and more specifically to a temperature control device for controlling heating and heat retention temperatures over time. The present invention relates to a temperature control device.

[Conventional Example] Temperature control devices for heating and keeping warm bedding of this type, such as electric blankets, used to have simple functions such as controlling to a preset constant temperature and maintaining that constant temperature for a predetermined period of time. However, recently, various methods have been developed that not only control the temperature at a constant level, but also use temperature sensors to detect room temperature, etc., and add this indoor temperature to the set temperature above to control heating and heat retention. proposals have begun to be made.

[Problems to be Solved by the Invention] Although the temperature control device described above takes indoor temperature as its parameter, for example, no attention is paid to changes in body temperature before going to bed, after going to bed, and before waking up. Therefore, it cannot necessarily be said that the control is suitable for the user.

This invention was made in view of the above problems, and its purpose is to provide temperature control that can perform temperature control over time according to changes in the user's body temperature when using bedding, etc. The goal is to provide equipment.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides heating and heating for bedding, etc.
A temperature control device for controlling heat retention, comprising a temperature/time setting means for setting the heating/warming temperature at arbitrary time intervals, and a storage means for storing the set value. The heating/warming temperature of the bedding etc. is controlled over time based on the time setting value.

[Example] Embodiments of the present invention will be described below based on the drawings.

1 and 2, 1 is an input device for setting temperature, time, etc. This input device 1 includes a set temperature input key (temperature setting means) la for setting the temperature, and an alarm control for alarm. Alarm stop input key 1b for the alarm to stop the alarm, control time setting input key (time setting means) lc for setting the time of a predetermined time pattern, and a control time setting input key (time setting means) lc for setting the time of a predetermined time pattern. The mode switching input key 1d starts from
Down key (shown in Figure 2) 1e.

1f is provided. In addition, with the control time setting input key 1c, for example, the sleep time for clock display, wake-up time for alarm, scheduled bedtime time (time before bedtime), and high temperature retention time after bedtime (time while sleeping) and a pre-wake-up high temperature retention time (time before wake-up). Signals from these key operations are input to a control device (for example, a CPU) 2. The control device 2 also receives temperature detection signals from a room temperature sensor 3 provided in a control box and a local temperature sensor 4 (shown in FIG. 3) provided at a predetermined portion of bedding, such as a blanket. is input. The control device 2 includes a memory (storage means) 2a in which data such as various setting values and control patterns inputted by key operations are stored.
In addition, there is a clock function for counting the time from the start of control based on this stored data, a key input reading function for manual input from the input device 1, a mode setting function for mode switching, time, setting. A display function for displaying values, etc., a temperature monitoring function for monitoring the temperature of the bedding based on the temperatures detected by the room temperature sensor 3 and the local temperature sensor 4, and a temperature output control for controlling the temperature of the bedding based on the set value, etc. It has functions.

The output of this control device 2 includes a display device 5 configured with, for example, an LCD, which displays the time, various temperatures, various set values, etc. using a display function, and a display device 5 that uses a temperature output control function to control the temperature of the bedding. and a heating control device 6.

An alarm device 7 that operates with a timekeeping function is connected.

Next, the temperature control device having the above configuration is applied to the blanket shown in FIG. 3 as bedding, and the operation of the temperature control device in that case will be explained based on the control pattern as an example shown in FIG. 4.

First, let 1 be the temperature control time of the air blanket for 7 hours, for example from 11:00 PM to 6:00 AM, and divide this into 3 areas: several minutes before going to bed, six hours while sleeping, and the number of minutes after waking up. and,
As shown by the solid line in the figure, the temperature of the hands and feet is often low during the few minutes before bedtime, so the temperature is set higher than the set temperature. During the 6 hours you sleep, your body is in the minimum maintenance state and does not require much heat retention, so the temperature should be set a little lower than the initial temperature setting. This is because people often feel hot and uncomfortable if the temperature remains the same as before going to bed. Also, wake up with enough strokes.

Each return tube in the body is activated and requires warmth, so set the temperature a little higher than the set temperature. This is because there is often a large difference between the bedding and the indoor temperature, and also because you feel chilly when you wake up.

This control pattern uses the timekeeping function of the control device 2 to set the control time to 7 hours. in this case.

Control time setting input key 1c, up/down key 1θ,
By operating 1f, the bedtime start time and bedtime end time are displayed on the display device 5, and the scheduled bedtime time is set.
Set several minutes before going to bed, six hours while sleeping, and ten minutes to wake up. Then, the setting data is stored at a predetermined address in the memory 2a by the input reading function. In addition, in the same manner as above, the temperature T1 is much higher than the set temperature T for several minutes before going to bed, the temperature T2 is slightly lower than the set temperature T for 6 hours while sleeping, and the temperature T2 is set slightly higher than the set temperature T for the number of strokes after waking up. The temperature is set to T3, respectively.

In this way, once a blanket with a control pattern suitable for the user is used, the temperature control of the blanket follows the two-dot chain curve as shown in the figure. In other words, conventional temperature control only takes parameters such as room temperature into consideration with respect to the set temperature T, so it can only perform regular control, whereas the temperature control of the present invention can control the temperature according to the user's needs. The temperature changes over time, that is, the temperature before going to bed, while sleeping, and before waking up can be set according to the user.
By adding indoor temperature and local temperature to this temperature, it is possible to control changes in body temperature requirements (sleeping curve: corresponds to the two-dot chain line curve in FIG. 4).

Further, if the scheduled bedtime from 11:00 pm to 6:00 am is to be temporarily changed, for example, to go to bed early or late, the mode switch key 1d is operated. Then, using the mode setting function of the control device 2, the time when the mode switching input key 1d is operated is regarded as the bedtime start time.

Subsequent temperature control is performed according to the above control pattern.

In the above embodiment, the temperature control device is applied to a blanket, but the temperature control device operates in the same way and produces the same effects when applied to other heating devices or other bedding.

"Effects of the Invention" As explained above, according to the present invention, the temperature control of bedding, etc. can be changed over time.In other words, since a time management function has been added to the temperature control, it can be used from the time of going to bed to the time of waking up. The temperature can be set according to the change in body temperature requirements (sleeping curve) of the user, and the temperature of bedding, etc. can be optimally controlled for each user.
