Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that automatically detects whether food or drinks are taken out or put into a refrigerator installed in a guest room of a hotel or inn, for example.

BACKGROUND ART Food and beverages stored in refrigerators installed in guest rooms at hotels and inns can be freely taken out and consumed by guests in the room.

In this case, it is impossible to know what and how much a customer has eaten or eaten unless a hotel or inn employee goes to each guest room and inspects the inside of the refrigerator. As a result, inspections were not only time-consuming, but also required a lot of manpower. In order to solve this problem, the present invention enables the front desk to manage the consumption status of food and drink in the refrigerator of each guest room.

The present invention will be explained in detail below based on the drawings. A large number of plate-shaped receivers 2 are installed vertically and horizontally inside a refrigerator 1, and they are partitioned by a peripheral wall 3 to form storage chambers 4, and it is preset where in these storage chambers 4 and what kind of food and drinks are to be stored. Then, when you take out food and drink from the storage chamber, the switch for that storage chamber operates and is electrically connected to the tally detection device 6 installed at the front. It is designed to immediately detect whether food or drink has been consumed.

The storage part 4 is closed at the front so that food and drinks 5 such as beer with horse mackerel and juice with horse mackerel can be put in and taken out from the entrance 14.

The storage section 4 may partition the inside of the refrigerator 1 and surround each receiver 2 installed in the refrigerator 1, or the storage section 4 may be formed by forming upwardly rising side walls on both sides of the receiver itself. ,
As shown in the figure, an independent rectangular cylindrical case may be used, the inside of the case may be used as a storage section, and the receiver 2 may be attached inside the case.

The receiver 2 has a plate shape whose width narrows from the front to the rear,
As clearly shown in FIG. 6, support shafts 17 and 18 protruding from both front sides of the case 3 are inserted into the distal ends of the side plates 15 and 16 of the case 3 so that they can be freely extended.

Further, as clearly shown in FIG. 5, the receiver 2 is inclined gradually upward from the front end side to the rear end side. In the figure, 8 is a spring 8, which is composed of a winding shaft 7 and a wire rod wound around it. As shown in FIG.
The supporting portion 12 is protruded in a direction orthogonal to the supporting portion 12 .

The support portion 12 is configured to support the receiver 2 by being engaged with a locking protrusion 19 of the receiver 2. The elastic strength of this spring 8 increases when the winding shaft 7 is rotated and the wire is wound around the winding shaft 7.
When the winding shaft 7 is rotated in the opposite direction to return the wire, the elastic strength of the support portion 12 is weakened.

Reference numeral 22 denotes a detection object using a reed switch, which is a detection object for the printed circuit board 2 installed upright behind the back wall 20 of the storage section 4.
It is attached to 1.

This reed switch is designed to be turned on and off by being attracted by two magnets attached to the receiver 2 and released when the receiver 2 moves up and down as food 5 is put in and removed from the receiver 2. The detection body 22 may be something other than a reed switch, such as a switch made of an electronic element, in which case the magnet 20 is not required.

A support 24 is provided on the entrance/exit side between the side walls 15 and 16 of the storage section 4, and is made higher than the receiver 2 so that the front side of the food and drink 5 placed on the receiver 2 is supported. This ensures that the load of the food and drink 5 is applied to the inner part of the receiver 2.

In addition, 25 in FIGS. 3, 4, 6, and 7 is the back wall 20.
It is an opening with a closed mouth.

As described above, the present invention supports the receiver 2 by the spring 8 and further includes the support body 24 that transmits the load of the food and drink 5 to the receiver 2. A load is reliably applied to the receptacle 2, and the detection body 22 can reliably detect whether an article is put in or taken out of the receptacle 2.

In particular, in the present invention, since the receiver 2 is sloped upward gradually from the distal end to the rear end, the load of food and drink placed on the receiver 2 and whose distal end is supported by the support 24 is transferred to the receiver. 2, and the detection by the detection body 22 is performed accurately.

Further, in the present invention, since the elastic strength of the support part 12 can be adjusted by rotating the winding shaft 7, the strength of the elastic strength of the support part 12 can be adjusted according to the weight of the food and drink 5 to be taken in and out of the receiver 2. It is possible to accurately detect the insertion and removal of the parts, and it is economical because there is no need to prepare various springs with different elastic strengths, and there is no need to manage parts or erroneously attach them to the receiver 2. By adjusting the elastic strength of the spring 8, the receiver 2 is activated only when a predetermined weight of food 5 is placed in or taken out of the receiver 2.
If it is made to be able to move up and down, the detection body 6 will not turn on and off even when an empty container is returned to the storage section 4 after taking out the food and drink 5. It is also possible to determine whether it is a container or not.

In the spring 8 of the present invention, the movable range is only a, as shown by the imaginary line in FIG. Changes in the weight of the food and drink 5 that are placed can be sensitively sensed, and therefore the up and down movement of the receiver 2 becomes accurate.

Although the spring 27 shown in FIG. 8 tends to lose its elasticity after long-term use, this does not occur with the spring of the present invention.

Since the spring of the present invention is made by winding a wire rod around the winding shaft 7, even if the length of the support portion 12 protruding from the winding shaft 7 is short, the total length of the wire rod is long.

Therefore, unlike a spring whose entire length is the same, the support part 12 can reliably sense the load applied to the receiver 2, and the vertical movement of the receiver 2 accurately corresponds to the load. Detection object 2
2 is electrically connected to the tally management device 6 as shown in FIG. If it is determined in advance, it is possible to detect which case of food and drink has been consumed at the front desk simply by operating the tally management device 6.

If you use an independent rectangular cylindrical case as the storage part 4 as shown in the figure, you can simply attach the receiver 2, spring 8, detector 22, etc. to it and install the case inside the refrigerator 1. Since the receiver 2, the spring 8, the detection body 22, etc. can be installed inside the refrigerator 1, installation inside the refrigerator 1 becomes simple and easy.
