Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic thermometer that displays a temperature detected by a temperature sensor on a liquid crystal display.
[0002]
[Prior art]
In this type of electronic thermometer, as shown in FIG. 11, a liquid crystal display 51 is provided on the front surface of a main body 50 made of a plastic case to display the temperature detected by the temperature sensor as a 7-segment number.
[0003]
There are an internal sensor type in which a temperature sensor is built in the main body 50 and an external sensor type in which a temperature sensor is provided inside a sensor rod or sensor probe attached to the main body 50. It is used to measure the temperature in trains, etc. The latter is used to measure the atmospheric temperature such as drying, water temperature, food fermentation temperature, freezing temperature, refrigeration temperature, heating / sterilization temperature at the center of the cooked food, etc. in use.
[0004]
Some internal sensor type electronic thermometers include a humidity sensor in addition to the temperature sensor to display both temperature and humidity on a liquid crystal display.
[0005]
[Problems to be solved by the invention]
By the way, recently, with the spread of air conditioners that automatically control the room to a comfortable temperature, general home thermometers that simply measure and display the room temperature are less practical and the demand is gradually decreasing. Although a thermometer with excellent design can also be expected to be used as an interior, an electronic thermometer that simply expresses the temperature as a 7-segment number as shown in FIG. 11 cannot be said to be suitable for a special interior. , Sales are not good because it lacks novelty and looks interesting.
[0006]
External sensor-type electronic thermometers that can measure food fermentation temperature, refrigeration temperature, heating / sterilization temperature, etc. are considered useful not only in the industrial field but also in general households. For example, housewives do not know the dough kneading temperature and fermentation temperature, which are the measurement target temperatures when making bread, or the optimal eating temperature of thawed frozen tuna for sashimi and cooking products that can sterilize pathogenic bacteria If you don't know the heating temperature, you can't use the electronic thermometer effectively, and you can check the optimum temperature and appropriate temperature for various measuring temperatures such as fermentation temperature and heating / sterilization temperature in the literature. This is very troublesome and is not so popular in ordinary households.
[0007]
Therefore, the present invention provides an electronic thermometer that is novel, interesting and easy to use, and not only displays the temperature detected by the temperature sensor numerically as in the prior art, but also the high and low of the temperature. It is a technical problem to make it possible to easily check the degree without actually knowing the degree visually or knowing the optimum temperature or appropriate temperature of various measurement target temperatures.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides an electronic thermometer that displays a temperature detected by a temperature sensor on a liquid crystal display, and a storage device having an image storage unit that stores an image corresponding to a temperature within a measurement range. And a control device for retrieving an image corresponding to the temperature detected by the temperature sensor from the image storage unit and displaying the image on a liquid crystal display.
[0009]
Since the electronic thermometer of the present invention displays not only the temperature detected by the temperature sensor but also the image corresponding to the detected temperature on the liquid crystal display, there is an appearance that is not found in conventional products, and the electronic thermometer New demand can be created.
[0010]
In particular, if the image displayed on the liquid crystal display is composed of a motif that expresses the degree of the temperature detected by the temperature sensor, it is possible to visually feel the degree of warmth or cold, or the degree of heat or cold. Since it can, it also doubles the fun.
[0011]
Further, when the still image corresponding to each temperature within the measurement range and the moving image corresponding only to the specific temperature are stored in the image storage unit, and the specific temperature is detected by the temperature sensor, the control device However, if a configuration is adopted in which a moving image is displayed on the screen of a liquid crystal display that displays a still image corresponding to the detected temperature, a movie (movie) suddenly appears on the screen of a still image that does not move. At the same time, consumers are intrigued by how many videos appear and how many sales of electronic thermometers can be expected.
[0012]
In addition, the image displayed on the liquid crystal display is composed of motifs representing the types of temperature to be measured such as the dough kneading temperature, the primary fermentation temperature, the secondary fermentation temperature, and the like. If it is stored in the image storage unit corresponding to the optimum temperature or appropriate temperature, check the optimum temperature and appropriate temperature of each measurement target temperature while looking at each image displayed on the liquid crystal display, from the dough kneading The temperature control up to the fermentation can be performed accurately without mistakes.
[0013]
In addition, even if the optimal temperature or appropriate temperature of each measurement target temperature is not known or forgotten, the control device uses the input signal from the key input device provided in the main body of the electronic thermometer to store the storage device. By scrolling and displaying each image stored in the image storage unit and the temperature corresponding to that image on the liquid crystal display, it is possible to easily and quickly check the optimum temperature and appropriate temperature for each measurement target temperature. Because it is possible, it is very convenient.
