  However, in the two-temperature type showcase described in Patent Document 1, it is not possible to mechanically detect whether or not the intermediate partition body is attached to the product display shelf, and it depends on the visual recognition of the store employee. ing. For this reason, there are cases in which it is forgotten that the intermediate partition body should be attached to the product display shelf, or cases where the intermediate partition body to be removed from the product display shelf remains attached.

  It is possible to detect with a sensor whether or not the intermediate partition is attached to the product display shelf, but in that case, a sensor is provided for each product display shelf or for each damper. The number of parts such as the sensor and the sensor mounting member is increased, and the number of sensors is increased, which complicates the wiring work for each sensor.

  The present invention has been made in order to solve such a problem, and an object thereof is to display a product for weak cooling on an upper product display shelf and a product for refrigeration on a lower product display shelf. In the first use mode for displaying the product, there is an abnormality in the operating state in which the intermediate partition body is not attached to the insertion part, or all the product display shelves have a product for low cooling or refrigeration. It is easy to reduce the number of parts and the number of wiring work by the abnormality of the operation state that the intermediate partition body is attached to the insertion part in the second use mode for displaying the product for sale. The purpose of the present invention is to provide a two-temperature type showcase that can be detected by the structure.

  In the present invention, a plurality of upper and lower stages of product display shelves are provided in a showcase main body, products for weak cooling are displayed on the product display shelves on the upper stage side, and products for refrigeration are displayed on the product display shelves on the lower stage side. In a dual temperature type showcase that is switchable between a first use mode for displaying and a second use mode for displaying weak cooling products or refrigerated products on all of the product display shelves, the interior of the showcase main body Side is provided in the up-and-down direction, the cool air passage through which cool air flows from the lower side to the upper side, the insertion portion formed on the product display shelf, and the insertion portion is detachably inserted and attached. An intermediate partition body for blocking the flow of cold air flowing in the cold air passage above the insertion position, and an intermediate partition body provided in the showcase main body and pushed by the intermediate partition body attached to the insertion section. A movable long elongated movable body, a detection switch for detecting that the movable body has moved, and a dual-temperature showcase in which the usage pattern is a first usage pattern or a second usage pattern. If the detection switch does not detect that the movable body has moved when the first use mode is instructed by the changeover switch and the changeover switch, or the second use mode by the changeover switch. When the detection switch detects that the movable body has moved, the determination unit determines that the operating state of the two-temperature type showcase is abnormal.

  Further, it is desirable to have an informing unit for informing the determination result of the determining unit.

  Further, an intermediate passage for guiding the cool air, which is communicated with the cool air passage and flows in the cool air passage, to the front side of the showcase body when the intermediate divider is inserted into the insertion portion. Are preferably formed.

  In the two-temperature type showcase according to the present invention, when the product for weak cooling is displayed on the upper product display shelf and the refrigerated product is displayed on the lower product display shelf in the first usage mode, Has an intermediate partition body attached to the insertion section of the product display shelf, and when the intermediate partition body is inserted into the insertion section, the movable body is pushed and moved by the inserted intermediate partition body. Then, the detection switch detects that the movable body has moved. Further, whether the two-temperature type showcase is used in the first usage pattern or the second usage pattern is instructed by switching the changeover switch. When the detection switch does not detect that the movable body has moved when the first usage pattern is instructed by the changeover switch, either the insertion of the intermediate partition body is forgotten or the instruction of the changeover switch is erroneous. Means that the operating state of the two-temperature showcase is abnormal. On the other hand, when the detection switch detects that the movable body has moved when the second use mode is instructed by the changeover switch, the intermediate partition body is erroneously inserted or the instruction of the changeover switch is incorrect. The operating condition of the two-temperature showcase is determined to be abnormal by the determination unit. Here, the movable body is one member that is formed in a long shape that is long in the up-down direction, and the movable body is movable and movable even when the intermediate partition body is attached to the insertion portion of any product display shelf. The movement of the body is detected by the detection switch. Therefore, it is sufficient to provide one movable body and one detection switch for detecting whether or not the intermediate partition body is inserted in any one of the insertion sections, and the operating state of the two-temperature showcase can be improved. The number of parts for detecting an abnormality is reduced and the wiring work of the detection switch is simplified.

  In addition, since the notification result of the determination unit is notified by the notification unit, it is possible to promptly notify an employee of the store that the operating state of the two-temperature type showcase is abnormal.

Also, when the intermediate partition is inserted into the insertion part of the product display shelf, the cool air flowing in the cool air passage is guided to the front side of the showcase body through the intermediate passage of the intermediate partition, so that the intermediate partition is Cooling air is suppressed from entering above the product display shelves equipped with, and the position above the product display shelves equipped with the intermediate partition provides an environment suitable for displaying products for weak cooling.

  The control device 15 installed on the upper part of the showcase body 3 indicates that the operating state of the two-temperature type showcase 1 is abnormal from the switching state of the changeover switch 15a and the insertion state of the intermediate partition body 12. A judging unit 19 for judging is provided. Specifically, since the intermediate partition 12 is not inserted into the insertion portion 10 when the first use mode is instructed by the changeover switch 15a, the movable body 16 is positioned at the protruding position and the detection switch 18 Is off, or the movable partition 16 is located at the retracted position because the intermediate partition body 12 is attached to the insertion portion 10 when the second use mode is instructed by the changeover switch 15a. When the detection switch 18 is turned on, it is determined that the operating state of the two-temperature type showcase 1 is abnormal.

  Further, the control device 15 is provided with an alarm unit 20 which is a notification unit for notifying the determination result when the determination unit 19 determines that the operating state is abnormal.

  In such a configuration, FIG. 1 shows a case where the two-temperature type showcase 1 is used in a second usage pattern in which the products for weak cooling or the products for refrigeration are displayed on all the product display shelves 9. ing. In the second usage mode, the intermediate partition body 12 is not inserted into the insertion section 10, and the intermediate partition body 12 is accommodated in the accommodation section 11 of the lowest product display shelf 9h. Then, since the intermediate partition body 12 is not attached to the insertion portion 10, all the dampers 13 are rotated to the lower position, and the cool air reaches the uppermost position in the cool air passage 5 as indicated by the black arrow. The non-cooled air flows through the non-cooled air passage 6 to the uppermost position as shown by the white arrow, merges with each other, and blows downward from the air outlet 7 to form an air curtain of cold air that covers the opening 2.

  In the second usage mode, the movable body 16 is not pushed by the intermediate partition body 12 inserted into the insertion portion 10, and is located at the projecting position as shown in FIG. 3 or FIG. 18 is in an off state without being pushed by the movable body 16. Since the detection switch 18 is off when the second usage pattern is instructed by the changeover switch 15a, the determination unit 19 determines that the operating state of the two-temperature type showcase 1 is normal, and the alarm unit No alarm will be issued from 20.

  On the other hand, in the second use mode, if the intermediate partition body 12 is accidentally inserted into any of the insertion portions 10, the damper 13 pushed by the intermediate partition body 12 rotates to the upper position. At the same time, the flow of cold air in the cold air passage 5 is blocked by the tip of the intermediate partition body 12 that has entered the cold air passage 5. Further, the movable body 16 is pushed by the intermediate partition body 12 whose tip portion is inserted into the cool air passage 5, the movable body 16 is rotated to the retracted position as shown in FIGS. 4 and 6, and is pushed by the movable body 16. Detection switch 18 is turned on. Then, when the detection switch 18 is turned on when the second use mode is instructed by the changeover switch 15a, the determination unit 19 determines that the operating state of the two-temperature showcase 1 is abnormal, and the alarm unit.

It has one detection switch 18 for detecting the rotation of 16. Therefore, even if there are a plurality of insertion parts 10 into which the intermediate partition 12 is inserted, it is not necessary to provide a plurality of detection switches corresponding to the insertion parts 10, and the intermediate partition 12 is inserted. One movable body 16 and one detection switch 18 may be provided as a member for detecting whether or not there is. Therefore, in this two-temperature type showcase 1, the number of parts for detecting that the operating state of the two-temperature type showcase 1 is abnormal is reduced and the wiring work of the detection switch 18 is simplified.

  In addition, in the two-temperature type showcase 1, the intermediate partition body 12 is housed in the housing portion 11 formed on the lowermost product display shelf 9h during the operation in the second usage mode. It is possible to prevent the situation in which the intermediate partition body 12 is lost in the form.

  In the present embodiment, an alarm is issued if the intermediate partition 12 is not inserted into the insertion portion 10 when the first usage pattern is instructed, and the second usage pattern is instructed.
