Abstract

(57) [Summary] [Purpose] To provide a card that can directly display the discomfort index. [Structure] A temperature display section 2 composed of a sensor whose color changes every 2 ° C. on a substrate 1, a humidity display section composed of a sensor whose color changes every 10%, and color classification according to the level of discomfort, It is characterized by having a discomfort index display unit 4 including a comfortable area 4A, a partial discomfort area 4B, a half discomfort area 4C, an all-member discomfort area 4D, and an discomfort area 4E that exceeds the patience limit.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a discomfort index display card capable of easily determining the discomfort degree of an office or home atmosphere.

[0002]

[Prior art]

 Some cards of this type have only a temperature display, some can only display temperature and humidity, but only a simple display. In fact, they are called "laundry cards". .

However, since its purpose is limited to washing and the like, it has become a neglected card especially for humidity display.

[0004]

[Problems to be solved by the device]

 Considering the usage of cards, it is common sense that they are in pockets in most cases. In this state, move to various places. Given this, the use of simply indicating whether or not it is washable is not appropriate.

Considering that people are expected to go to various places in their pockets and their body and emotions are controlled by the environment, the discomfort index used in the weather is If the display can be provided in the form of a simple card, the index itself will also have citizenship.

An object of the present invention is to provide a discomfort index display card capable of directly displaying a discomfort index, which is different from the conventional card which only displays a value of temperature or humidity alone.

[0007]

Means for Solving the Problems The present invention provides a temperature display unit that changes color at a predetermined temperature, a humidity display unit that changes color at a predetermined humidity, and color classification according to the level of discomfort. It has a discomfort index display part in which the corresponding area is specified in advance by a combination of color display of the temperature display part and the humidity display part.

[0008]

[Action]

 In the present invention, to obtain the discomfort index, the intersection point between the temperature displayed on the temperature display section and the humidity displayed on the humidity display section is obtained, and the discomfort is determined by observing the area on which the intersection point lies. The index is calculated.

[0009]

【Example】

 FIG. 1 shows an embodiment of the discomfort index display card of the present invention.

A substrate 1 has a temperature display section 2 arranged in the X-axis direction and a humidity display section 3 arranged in the Y-axis direction. The temperature display unit 2 is a temperature sensor made of a cholesteric liquid crystal whose color changes at a predetermined temperature. In this example, the temperature is changed in steps of 2 degrees to indicate the ambient temperature. Further, the humidity display unit 3 generally uses a sensor whose color changes every predetermined humidity, and generally changes from gray to pink when the humidity is sensed. In this example, the humidity of the surroundings is indicated in steps of 10%. Since these temperature and humidity sensors themselves are publicly known, their details are omitted. Further, 4 is a discomfort index display portion, which is divided based on the discomfort index as described later.

The discomfort index is calculated, for example, by the following formula. [Discomfort index] = 0.99T + 0.36t + 41.5 (1) where T is temperature and t is dew point. The discomfort index is 70 to 74, which is partly discomfort, 75 to 79 is half discomfort, 80 to 85 is discomfort for all, and 86 and above are discomfort beyond the patience limit. This dew point t is a quantity directly related to humidity, so if the temperature and humidity can be measured, the discomfort index can be obtained.

Based on the above formula (1), the discomfort index is calculated from the temperature and the humidity, and the comfortable area 4A, partly uncomfortable area 4B, half uncomfortable area 4C, everyone uncomfortable area 4D, and discomfort exceeding the limit of patience The substrate 1 is divided into five regions 4E and printed on the substrate 1 in different colors, for example. That is, in the discomfort index display card of the present invention, the area to which the coordinates (X, Y) of the cross point of temperature (X) and humidity (Y) belong represents the discomfort index.

In the embodiment shown in FIG. 1, the X-axis of the temperature display section 2 and the Y-axis of the humidity display section 3 are oblique to each other. You can

[0014]

[Effect of device]

 As described above, the discomfort index display card of the present invention is classified according to the discomfort level, such as the temperature display section that changes color at each predetermined temperature, the humidity display section that changes color at each predetermined humidity. In addition, the discomfort index display section that specifies the corresponding area in advance by the combination of the color display of the temperature display section and the humidity display section can be used to directly know the degree of the discomfort index without bothering to calculate. Therefore, it is possible to grasp the local climate, such as offices and the inside of a house, because a better expression for the environment can be obtained. In addition, this card has the effect of making the discomfort index more common.
