The output unit is for outputting the value from the distance sensor 21. The output unit of the present embodiment is a thermal printer, which receives data from the distance sensor 21 and prints out paper through the paper outlet 113.
The distance sensor 21 is provided at an end of the housing. In this embodiment, the distance sensor 21 is disposed at the top end of the housing, the elastic member is a spring 23, one end of the spring 23 is fixed on the upper portion of the housing, the other end of the spring naturally sags and is connected to the supporting block 253, and when the spring 23 is in a natural state, the armrest 251 is at an original height. When the subject's elbow is placed on the armrest 251, the spring 23 is in a stretched state, the armrest 251 is lowered in height, and the distance between the distance sensor 21 and the armrest 251 increases.
The method for measuring the man-machine height of the cabinet table top by using the measuring device comprises the following steps:
(1) The tested person stands upright, the upper arm is naturally vertical, the elbow is bent at 90 degrees and placed on the armrest 251, and the armrest 251 is adjusted to be attached to the bottom of the elbow; at this time, the armrest 251 receives pressure from the elbow, the spring 23 is stretched, the height of the armrest 251 is lowered, and the distance from the sensor 21 to the armrest 251 is increased.

F＝H-D ①
wherein H is the fixed height of the distance sensor 21 from the ground when the device is installed;
further, the washing and dining area table top height WP is calculated by the formula (2):
WP＝F-X ②
wherein the value range of X is 5-25 cm; x=15 cm in this example;
the cooking area mesa height C is calculated by equation (3):
C＝F-Y ③
wherein the value range of Y is 15-35 cm; y=25 cm in this example; because the cooking area table top is not higher than the washing and dining area table top in consideration of the arrangement of cooking appliances, Y is not less than X;

(4) The elbow of the person to be measured leaves the armrest 251, the armrest 251 is not stressed any more, the original height is restored, and the next measuring activity of the person to be measured is performed.
Example 2
Example 2 differs from example 1 in that: the distance sensor 21 is installed in the bottom of the shell, the elastic piece is a spring 23, one end of the spring 23 is fixed in the bottom of the shell, the other end of the spring 23 is naturally placed upwards and is connected with the supporting block 253, and the sufficient shrinkage deformation range of the spring 23 is ensured. When the spring 23 is in a natural state, the spring 23 is slightly compressed, and the armrest 251 is at an original height. When the subject's elbow is placed on the armrest 251, the degree of compression of the spring 23 increases, the height of the armrest 251 decreases, and the distance between the distance sensor 21 and the armrest 251 decreases.
Thus, in the measuring method step (2), the formula (1) of the elbow height F is: f=h+d, where D is the distance between the armrest 251 and the distance sensor 21, and H is the height of the distance sensor 21 from the ground when the device is installed.
Example 3
Example 3 differs from example 1 in that: the distance sensor 21 is installed at the top of the shell, the elastic piece is a spring 23, one end of the spring 23 is fixed at the bottom of the shell, the other end of the spring 23 is naturally placed upwards and is connected with the supporting block 253, and the sufficient shrinkage deformation range of the spring 23 is ensured. When the spring 23 is in a natural state, the spring 23 is slightly compressed, and the armrest 251 is at an original height. When the subject's elbow is placed on the armrest 251, the degree of compression of the spring 23 increases, the height of the armrest 251 decreases, and the distance between the distance sensor 21 and the armrest 251 increases.
Thus, in the measuring method step (2), the formula (1) of the elbow height F is: f=h-D, where D is the distance between the armrest 251 and the distance sensor 21, and H is the height of the distance sensor 21 from the ground when the device is installed.
Example 4
Example 4 differs from example 1 in that: the distance sensor 21 is installed at the bottom of the casing, the elastic element is a spring 23, one end of the spring 23 is fixed at the top of the casing, the other end of the spring is naturally drooping and connected with the supporting block 253, and when the spring 23 is in a natural state, the armrest 251 is at an original height. When the subject's elbow is placed on the armrest 251, the spring 23 is in a stretched state, the armrest 251 is lowered in height, and the distance between the distance sensor 21 and the armrest 251 is reduced.
Thus, in the measuring method step (2), the formula (1) of the elbow height F is: f=h+d, where D is the distance between the armrest 251 and the distance sensor 21, and H is the height of the distance sensor 21 from the ground when the device is installed.
Those skilled in the art will recognize that the same or similar technical effects as those of the above embodiments can be expected when the technical parameters of the present invention are changed within the following ranges:
when the armrest 251 is higher than the distance sensor 21, formula (1): f=h+d; when the armrest 251 is lower in height than the distance sensor 21, formula (1): f=h-D.
The output unit comprises a display, and a screen of the display is arranged on the panel 11; the output unit comprises a voice broadcasting device, and a loudspeaker of the voice broadcasting device is arranged on the panel 11.
The foregoing description is only illustrative of the preferred embodiments of the present invention, and therefore should not be taken as limiting the scope of the invention, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
