Description of the Related Art As shown in FIG. 6, a conventional electric blanket of this type includes a blanket body 3 provided with an electric heater 1 and a temperature detection means 2 for detecting the temperature of the electric heater 1; A temperature setting means 4 for setting the temperature of the electric heater 1 and a control means 10 for controlling energization of the electric heater 1 based on the temperature detected by the temperature detection means 2 and a signal from the temperature setting means 4 were provided. This configuration has the effect that, during use, the control means 10 controls the energization of the electric heater 1 so that the temperature reaches the appropriate temperature set by the user using the temperature setting means 4.

Problems to be Solved by the Invention However, the above-mentioned system has the following problems. In other words, when waking up, the human body moves from a previously resting state to the wake-up motion and begins various activities of daily life. On the other hand, in people with abnormalities in peripheral cutaneous vasomotion, such as elderly people, sufficient vasodilation does not occur even when they wake up. This places an excessive burden on cerebral blood vessels or coronary blood vessels, leading to hypertension, cerebral hemorrhage, and other problems. In the above-mentioned method, the optimal temperature set by the user is maintained constant from sleep to wakeup, so when the user wakes up, the peripheral skin blood vessels of the user are dilated to a certain level; The problem was that blood vessels could not be expected to dilate until the preliminary level (v) in preparation for an increase in blood pressure due to the activity of blood vessels.

Therefore, the present invention solves such conventional problems, and in order to further warm up the user's body before getting up, dilate the peripheral skin blood vessels to a certain extent, and prepare for the increase in blood pressure caused by various activities after getting up, the present invention has been developed. The purpose is to change the set temperature to a higher temperature side from before the time.

Means for Solving the Problems In order to achieve this object, the present invention provides a blanket body provided with an electric heater and a first temperature detection means for detecting the temperature of the electric heater, a temperature setting means for setting a wake-up time; a wake-up time setting means for setting a wake-up time; and a timer that outputs a signal when a predetermined period of time before the set wake-up time occurs according to a signal from the wake-up time setting means. , a second temperature detection means, a setting change means that operates in response to a signal from the timer and changes a set temperature in accordance with a signal from the second temperature detection means, a signal from the first temperature detection means, and a and control means for controlling energization to the electric heater based on the difference between the signal from the setting change means and the signal from the setting change means.

Function In the above configuration, the electric blanket of the present invention controls the electricity supply to the electric heater so that the set temperature is reached until a certain time before the wake-up time, and changes the set temperature and turns on the electric heater when the temperature reaches the set temperature until a certain time before the wake-up time. It has the effect of controlling electricity supply to the heater.

Example Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram of an electric blanket in a first embodiment of the present invention. In the figure, 1 is an electric heater, 2 is a first temperature detection means for detecting the temperature of the electric heater 1, and 3 is a first temperature detection means for detecting the temperature of the electric heater 1;
4 is a temperature setting means for setting the temperature of the electric heater 1; 5 is a wake-up time setting means for setting a wake-up time; 6
7 is a timer that outputs a signal at a predetermined time before the set wake-up time based on the signal from the wake-up time setting means 5; 7 is a second temperature detection means; here, a skin temperature detection means for detecting skin temperature; As a means. Reference numeral 8 indicates a setting change means which starts operation by the timer 6 and changes the set temperature to a high temperature side in response to a signal from the skin JfJ temperature detection means 7, and reference 9 indicates a signal from the first temperature detection means 2 and a setting change means 8. This is a control means that controls energization to the electric heater 1 based on the difference between the signal and the signal.

In the above configuration, the operation will be explained using FIG. 2. The user sets the wake-up time t1 in advance using the wake-up time setting means 5.
is set, and preheating is started at the high temperature setting TO. After that, when the user goes to bed, the user changes the setting to the desired temperature setting T1 and goes to sleep.

Since there is no signal from the timer 6, the setting change means 8 outputs the set temperature T1 set by the temperature setting means 4 as it is to the control means 9, and the control means 9 receives the set temperature and the signal from the first temperature detection means 2. The energization to the electric heater 1 is controlled based on the difference between the two. Next, when time passes and reaches t□, which is a certain period of time before the set wake-up time t1, a signal is output from the timer 6, and the setting change means 8 uses the skin temperature detection means 7 based on the relationship shown in FIG. The change value T2 of the set temperature is calculated from the skin temperature Ts detected by the skin temperature Ts and outputted to the control means 9, and the control means 9 operates electrically so that the heater temperature detected by the first temperature detection means 2 becomes the set temperature T2. Power supply to the heater 1 is controlled.

Due to the above action, peripheral cutaneous blood vessels expand to warm the user's body before waking up, and prepare for the rise in blood pressure due to advanced cardiac function and increased cardiac output caused by various activities after waking up, resulting in hypertension. It has the effect of preventing diseases such as cerebral hemorrhage and cerebral hemorrhage. In addition, since the skin temperature is detected and the heating temperature is calculated based on it, you can wake up comfortably without worrying about the temperature in your bed rising too much and causing depression or sweating.

Next, as a second embodiment of the present invention, the second temperature detection means 7 may detect the temperature inside the bed in which the electric blanket is arranged, and in this case, the setting change means 8 Based on the relationship shown in the figure, a change value of the set temperature is calculated from the temperature inside the bed and outputted to the control means 9.

The above action provides the same effect as the above embodiment, and since the temperature inside the bed is detected and the heating temperature is calculated based on it, the temperature inside the bed rises excessively, causing depression and sweating. You can wake up comfortably without having to worry about it happening.

Further, as a third embodiment of the present invention, the second temperature detection means 7 may detect the room temperature, and in this case, the setting change means 8 detects the temperature inside the bed based on the relationship shown in FIG. A change value of the set temperature is calculated and outputted to the control means 9.

Due to the above-mentioned action, the same effect as in the above embodiment can be obtained, and since the room temperature is detected and the heating temperature is calculated based on it, the temperature inside the bed may rise excessively, causing depression and sweating. You can wake up comfortably without worrying.

Effects of the Invention As described above, the electric blanket of the present invention provides the following effects.

Since the set temperature is automatically changed to a higher temperature a certain period of time before waking up, the user's body warms up and peripheral skin blood vessels expand before waking up. Therefore, it is possible to prepare for the increase in blood pressure due to the advancement of cardiac function and increase in cardiac output brought about by various activities after waking up, and diseases such as hypertension and cerebral hemorrhage can be prevented.
