Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a bathtub for home use, infant use, etc.

0002

[Conventional technology]

The temperature of the water in the bathtub corresponds to the physical conditions of healthy people, sick people, infants, etc. It is desirable to set the temperature to the optimum temperature. Traditionally, this determination of water temperature was made at the bathtub. You can check the temperature by putting a thermometer into the hot water in the bath, or by dipping your hand into the hot water to feel the temperature. Check the temperature of the water by turning it off or visually checking the amount of steam rising from the water in the bathtub. It is only a method of determining the temperature of the water in the bathtub, and it is possible to accurately measure the temperature of the water in the bathtub visually. Bathtubs that can be judged are currently unknown.

[Problem that the idea aims to solve]

However, the conventional method of checking or determining the temperature of water in a bathtub does not When using a meter, the scale is small and difficult to read, making it easy to misunderstand and measurement was troublesome. Also, when you put your hand in hot water and judge the water temperature by feel, There was a tendency for errors to occur between the exact water temperature and the water temperature, depending on the physical condition of the person making the judgment. Sara When determining the water temperature by visually observing the water vapor rising from the water, it is important to check the temperature of the atmosphere. Since the amount of water vapor reflected in the eye changes, there may be a large difference between the visually judged water temperature and the actual water temperature. It was easy to make large errors. Therefore, people may get burnt by getting into hot water, or they may think it is hot water. People often make the mistake of thinking that when they soak in a bathtub, it turns out to be water. It was heavy. An accident caused by such a misunderstanding occurred recently when a man was hospitalized at the hospital shortly after his birth. An accident occurred in which an infant was accidentally placed in a hot bath and died.

0004 This invention was made to solve this problem, and the water temperature can be visually detected. The purpose of the present invention is to provide a bathtub that can be accurately determined.

[0005]

[Means to solve the problem] The present invention is a bathtub in which the water temperature can be determined visually. The goal has been achieved. This is because the inner surface of the bathtub changes color depending on the temperature of the water. A pattern that corresponds to the temperature of the water is applied using a thermochromic paint, and the color change of this thermochromic paint The structure is such that the water temperature can be checked by

[0006]

[Effect]

In the bathtub of this invention, the water temperature inside the bathtub increases to approximately 38℃, 42℃ and 45℃. When the temperature exceeds ℃, each thermosensitive color-changing paint changes color to transparent in response to these temperatures. , a pattern drawn on the surface of the bathtub inside each thermochromic paint appears. child Based on the pattern that appears, you can visually determine whether the current water temperature is at an appropriate temperature. can do. In addition, when determining the water temperature above, the bathtub should be measured from the side to the bottom. Draw various patterns on the surface and apply the temperature-sensitive color-changing paint on them. Visualize the temperature difference between the surface and bottom of the water that occurs when you boil the water in the bathtub. It can be checked more quickly and the bottom side feels warm when a person enters the bathtub. You can prevent such dissatisfaction from occurring.

【Example】

An embodiment of the bathtub of the present invention will be described with reference to FIG. For example, in the case of a bathtub for infants 1, the bathtub of the present invention has There is a pattern 1a of flowers, fish, etc. and a red tile pattern 1b to improve the design, respectively. be painted. The surface of pattern 1a, such as flowers, will turn transparent if the contact temperature exceeds 38℃. The first commercially available thermochromic paint 2 is applied, and at the same time the surface of the tile pattern 1b is coated. , a commercially available second temperature-sensitive color-changing paint 3 that turns transparent when the contact temperature reaches 42°C or higher is applied. When the temperature of the water in bathtub 1 reaches 38℃ or higher, the first temperature-sensitive discoloration occurs. For example, the color paint 2 changes from the same color as the bathtub 1 to transparent, and a pattern 1a such as a flower appears. , you can visually confirm that the temperature has reached the optimum temperature for your baby's bath. Also When the water temperature reaches 42°C or higher, the second thermosensitive color-changing paint 3 is heated to the same temperature as bathtub 1, for example. The temperature changes from color to transparent and red tile pattern 1b appears, making it unsuitable for infants to bathe. You can visually check the state of the hot water.

[0008] Furthermore, as an example, we will show the case of a general bathtub (not shown). The inner side and bottom of the bathtub also have flower, fish, etc. patterns and red tile patterns in the same way as above. be painted. The surface of this flower pattern turns transparent when the contact temperature exceeds 35℃. A third commercially available temperature-sensitive color-changing paint is applied to the surface of the tile pattern. Coated with commercially available No. 4 thermosensitive color-changing paint that turns transparent when the contact temperature exceeds 45°C. be done. When the temperature of the water in the bathtub reaches 35℃ or higher, the above-mentioned third temperature-sensitive color change occurs. For example, the paint changes color from the same color as the bathtub to transparent, and patterns such as flowers appear, and the temperature of the water changes. You can confirm that the temperature is optimal for bathing. In addition, the fourth thermosensitive color-changing paint For example, if the color changes from the same color as the bathtub to transparent, a tile pattern will appear, and the water temperature will change. You can confirm that the hot water is not suitable for your body.

[0009] In addition, in this example, the model that appears on the inner peripheral surface of the bathtub 1 when the water temperature is suitable for bathing is In order to improve the design, we used flowers such as 1a, but it is not limited to this. Patterns and colors can be set as desired. In addition, in this example, a red mark is used to indicate hot water. I used tile pattern 1b, but other oranges, blacks, and other warning colors and patterns can also be used. Can be set at will. In addition, the temperature-sensitive color-changing paints that change color depending on the temperature of the water listed above are It is not limited to this product, but also other commercially available products that change color to any color based on the temperature of the water. A thermochromic paint may also be used.

[Effect of the idea]

Just by looking at the inside of the bathtub of this invention, you can tell whether the water temperature is too hot or too lukewarm. This will help prevent you from accidentally taking a bath that is too warm or causing a burn. Accidents can be prevented. It is especially easy to adjust the water temperature in bathtubs for infants. Ru.
