In order to solve the above-mentioned problems, the present invention provides a water bed temperature controller having the following means.

[0005] Temperature Controller for waterbed of claim 1 has the following means. (1) Means for digitally displaying the set temperature of water in the water mattress and the current temperature of water in the water mattress measured by the temperature sensor. (2) Reservation timer means for reserving the heater for heating the water in the water mattress after a desired number of days has elapsed and for digitally displaying the set number of days for the reservation. In this specification including the claims, "data
"Digital display" means numbers, letters, symbols or barcodes.
Display.

[0006] Temperature Controller for waterbed of claim 2 has the following means. (1) Means for digitally displaying the set temperature of water in the water mattress and the current temperature of water in the water mattress measured by the temperature sensor. (2) Reservation timer means for reserving the heater for heating the water in the water mattress after a desired number of days has elapsed and for digitally displaying the set number of days for the reservation. (3) Water leak alarm means which includes a water leak sensor for detecting water leak of the water mattress and issues an alarm when the water leak sensor detects water leak of the water mattress.

[0009]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a water bed temperature controller. The water bed temperature controller 1 includes a heater 5 for heating water in the water mattress 3 and a temperature sensor 7 for measuring a current temperature of water in the water mattress 3. The heater 5 is
As shown in FIG. 3, it is disposed between a safety liner 9 surrounding the water mattress 3 and a support 11 outside the safety liner 9. The temperature sensor 7
When this is installed alone, it is installed outside the safety liner 9 surrounding the water mattress 3 as shown in FIG.

Thus, in the present invention, the temperature controller 1 for the water bed uses the liquid crystal and the light emitting element to determine the set temperature of water in the water mattress 3 and the current temperature of water in the water mattress 3 measured by the temperature sensor 7 There is provided a current temperature / set temperature display unit 13 for digitally displaying by means such as. The current temperature / set temperature display section 13 always displays the set temperature digitally, but displays the current temperature digitally while the current temperature display button 15 is pressed. Reference numeral 17 denotes a temperature setting button, reference numeral 19
Is a temperature increase / reservation days increase button, and reference numeral 21 is a temperature decrease / reservation days decrease button. To change the set temperature, press the temperature setting button 17 and press the temperature increase / reservation days increase button 19 or the temperature decrease / reservation days decrease button 21
Press. To raise the set temperature, press the temperature setting button 17 while pressing the temperature increase / reservation days increase button 19, and to lower the set temperature, press the temperature setting button 17 and press the temperature decrease / reservation days decrease button 21.
push. The reason why the two buttons must be pressed at the same time when the set temperature is changed is to prevent the set temperature from being changed by a mischief such as an infant.

Further, the water bed temperature controller 1 is provided with a reservation timer means for operating the heater 5 for heating the water in the water mattress 3 after a desired number of days has elapsed. Reference numeral 23 denotes a reservation button.
In order to operate the heater 5 after elapse of a desired number of days by the reservation timer means, for example, the reservation button 2
While pressing 3, the temperature increase / reservation days increase button 19 or the temperature decrease / reservation days decrease button 21 is pressed. In this case, when the temperature increase / reservation day increase button 19 is pressed, the number of reservation days increases, and when the temperature decrease / reservation day decrease button 21 is pressed, the number of reservation days decreases. By the way, if the number of reservation days is 1
On the fifth day, the heater 5 starts operating after 15 days. The reason why the two buttons must be pressed at the same time when performing the reservation operation is to prevent the reservation state from being changed by a mischief such as an infant. Reference numeral 24 denotes a reservation cancel button. The set number of reservation days is digitally displayed on the number-of-reservation-days display section 25 using a liquid crystal, a light-emitting element, or the like.

Further, the water bed temperature controller 1 is provided with a water leak sensor 27 for detecting a water leak of the water mattress 3 and the water leak sensor 27.
Is provided with a water leak alarm means for issuing an alarm when water leak of the water mattress 3 is detected. Water leak sensor 2
7 is provided between the water mattress 3 and the safety liner 9 as shown in FIG. It is desirable that the water leak sensor 27 is housed in the same package 29 as the temperature sensor 7, and the package 29 is disposed between the water mattress 3 and the safety liner 9.
Reference numeral 31 denotes a water leak warning lamp. In the illustrated example, when the water leak sensor 27 detects a water leak from the water mattress 3, the water leak alarm lamp 31 is turned on and an alarm buzzer is activated as an alarm. The reference numeral 33 indicates a buzzer stop button.
