Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial Field of Application] The present invention relates to a notification device for a bath that notifies the outside of the temperature of hot water in a bathtub, the elapsed time of bathing, etc.

[Prior Art] Conventionally, as a management device related to bathing, for example, a device that notifies that a certain amount of water has accumulated in a bathtub is known. Also, JP-A-51-
As shown in Japanese Patent No. 11478, there is also a known proposal in which an exterior body floating on a temperature-sensitive liquid issues an alarm when the temperature of the temperature-sensitive liquid reaches a predetermined temperature.

[Problems to be Solved by the Invention] The conventional management device described above can detect when a certain amount of water has accumulated in the bathtub. Also, Tokukai Akira
In the proposal shown in Japanese Patent No. 51-11478, it is possible to know when the temperature of the temperature-sensitive liquid has reached a predetermined temperature. That is, these devices can manage the bath before taking a bath.

However, in these conventional technologies,
While taking a bath, in other words, the bathing situation cannot be controlled. For this reason, in the past, for example, children's bathing conditions were decided based on their parents' intuition, and as a result, the bathing time was long and harsh for the child, or the water was too hot even if the bathing time was short. Furthermore, there were other drawbacks, such as people getting too absorbed in playing and taking a long bath, and not bathing properly, which meant that bathing, which was meant to promote health, ended up harming the health of children and infants.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks by providing a bath notification device that can appropriately manage bathing conditions.

Composition of the invention [Means for solving the problem] The bath notification device of the invention has the following features: for a buoyant body that floats on hot water in a bathtub, when the buoyant body floats on the hot water, it responds to the temperature of the hot water. A temperature sensor that generates an output, a temperature display device that displays the temperature detected by the temperature sensor so that it can be confirmed from the outside of the buoyant body floating in hot water, and an arbitrary time limit that can be set and an operation time limit. a timer that generates an output when the temperature sensor reaches a preset time limit; and a notification device that emits a sound to the outside of the buoyant body when the output of the temperature sensor exceeds a preset temperature and the time limit of the timer has elapsed for a predetermined time. Each of the devices is characterized by being provided in a waterproof state with a built-in power source.

[Function] The bath notification device of the present invention having the above configuration displays the temperature detected by the temperature sensor on the temperature display device when the buoyant body floats in hot water, and the output of the temperature sensor changes to a predetermined value. When the temperature exceeds the specified time limit of the timer, the notification device works to emit a sound to the outside of the buoyant body. As a result, even if a small child or the like is absorbed in playing, the child can easily know that the predetermined bathing conditions consisting of the water temperature and the elapsed bathing time have been met.

[Example] Next, the configuration of an example of the present invention is shown in Figures 1 to 4.
This will be explained using figures.

An electronic block 2 is sealed in a waterproof state in the central part of a vinyl buoyant body 1 as a toy in the shape of a fish, and in this sealed state, temperature and time are displayed on the upper surface of the central part of the buoyant body 1, respectively. 4, and a speaker 5 is located on the side of the central part of the buoyant body 1.
The buoyant body 1 is installed with only the sound-generating part exposed, which will not be affected even if it gets wet, and a thermistor or the like that generates an output corresponding to the temperature of the hot water is installed at the front of the lower surface of the buoyant body 1 (on the left side in Figure 3). A temperature sensing element 6 is attached, and a magnet 8 is attached to the center of the lower surface of the buoyant body 1.
When the buoyant body 1 is placed on the floor etc., the buoyant body 1 is dented and the magnet 8 moves upward, and when the buoyant body 1 is floated in hot water, the buoyant body 1 is in the state shown in FIGS. 2 and 3. As it swells downward,
It descends due to its own weight and controls the power switch reed switch 7 in the electronic block 2 to be turned off (when rising) and on (when descended). On the side of the electronic block 2, there is a mercury switch 12 that is turned on when the buoyant body 1 is in a nearly vertical state above the water surface via a weight 9, a string 10 with a length corresponding to the amount of hot water required in the bathtub, and a hook 11. A magnet 13 is attached to the top surface of the buoyant body 1, which moves left and right when operated to switch the control by the electronic block 2 between temperature/timer combination management and a stopwatch. Bottom rear (3rd
A thermoelectric element 14 for converting thermal energy into electrical energy is attached to the right side of the figure.

Next, FIG. 4 is an electric circuit diagram of this embodiment, in which the output from the temperature sensing element 6 is transferred to the A/D converter 15.
is input to the display element 3 via the decoder 16 to display the temperature of hot water on the display element 3 when the buoyant body 1 is floated in hot water, and is also input to each digital comparator 17 to 20 for each comparison. Vessel 17-2
From 0, the temperature of hot water is set by digital setting device 21-2.
For example, when the temperature set in step 4 reaches 50℃, 38℃, 40℃, 42℃, each output generates an output, for example, a monostable multivibrator 25 that generates an output for 30 seconds, or a temperature and timer. Combination control reed switch 26 and each AND circuit 27
- 29, the OR circuit 34 is connected to the counters 31 to 33 which count the pulses from the reference time generation circuit 30 by a predetermined number corresponding to 20 minutes, 15 minutes, and 10 minutes.
In addition to being input to the speaker 5 through the connection oscillation circuit 35, the electronic sound oscillation circuit 36, and the speaker drive circuit 37, the mercury switch 12 for detecting hot water level, which is grounded via a resistor R, and the seconds, minutes, and hours are also input to the speaker 5. The outputs from the clock circuit 38 formed by a counter, the timer circuit 39 formed by a digital comparator and a setting device, and the alarm setting reed switch 40 are also output from the OR circuit 3.
4 and each circuit 35 to 37 to the speaker 5, and the display element 4 displays the time according to the output from the clock circuit 38.

Further, the drive circuit 37 of the speaker 5 includes a reed switch 41 for setting a stopwatch, and a frequency divider 4.
2. Outputs from audio frequency generators 44 to 53 that generate each electronic voice of "Hito-tsu", "Futa-tsu", etc. The circuit receives power from the thermoelectric element 14 via the diode D and power from the storage battery 54 built into the electronic block 2. +V1 is supplied directly to the time display system, and other power supplies are supplied via the reed switch 7 for the power switch. +V2 is supplied.

Next, the operation of this embodiment will be explained.

Bath notification device 55 configured in this way
In the display element 4, the time is always displayed regardless of whether the reed switch 7 is on or off.
When the notification device 55 is placed on the floor or the like and is not in use, the magnet 8 is connected to the buoyant body 1.
The temperature T and stopwatch S systems do not operate because the reed switch 7 is turned off after entering the room.

Next, when the notification device 55 is placed in the bathtub with the weight 9 attached to the buoyant body 1 and the water tap is opened,
As the water level in the bathtub rises, the magnet 8 descends and the reed switch 7 is turned on, but the speaker 5 does not sound because the mercury switch 12 is vertical, but when the water level reaches a predetermined level, the string 10 is turned on. In order to keep the buoyant body 1 in a vertical position with tension, the mercury switch 12 takes a horizontal position and turns on, and each circuit 35 to 37 of the speaker 5 system operates via the OR circuit 34, causing the speaker 5 to sound.
This makes it easy to know that the water level in the bathtub has reached a predetermined level.

Next, in this state, remove the weight 9 etc. from the buoyant body 1 and ignite the burner in the bathtub.The temperature of the water in the bathtub will rise and the temperature at the bottom may be low, so stirring it will bring it to just the right temperature. The surface temperature of hot water is 50
℃, the comparator 17 generates an output, and the speaker 5 is activated for, for example, 30 seconds determined by the monostable multivibrator 25, making it easy to know that the water has boiled.

Next, in this state, for example, if you put your child in hot water and slide the magnet 13 to the T position, the appropriate bathing time corresponding to the temperature of the water, for example 20 degrees at 38°C.
After 15 minutes at 40°C and 10 minutes at 42°C, the output from each comparator 18 to 20 activates the speaker 5, which allows appropriate control of bathing. When the magnet 13 is slid to the S position, the speaker 5 makes a sound of "one" and "two" at preset time intervals, allowing you to count the numbers, especially when bathing children before entering school. It is suitable for management, and when the magnet 13 is slid to the A position, the speaker 5 is activated at a preset time, and it is possible to finish bathing at the required time.

The time setting of the timer circuit 39 and the time limit setting of each counter 31 to 33 are operated by a magnetic sensor type key switch (not shown) which is activated by lightly pressing a magnetic plate, and the circuit reset after the speaker 5 is activated is performed by a buoyant body. This is done by turning off the reed switch 7 by pressing the magnet 8 on the bottom surface of the 1. In addition, the power source can be a photoelectric element such as a solar cell, or it can be used in combination with each power source in the embodiments or as an individual power source. Also, the buoyant body 1 can have any shape that is popular among children and the like.

In this way, the bath notification device of this embodiment has the effect of comprehensively managing bathing and meaningfully promoting health through bathing.

Effects of the invention According to the bath notification device of the invention, bathing conditions can be easily managed, the original purpose of bathing can be fully demonstrated, and the health of children and infants can be further promoted. be effective.
