It is made.

  Here, the inner duct 5 is provided with a cooler 7 and a blower fan 8. Further, an inner air outlet 9 and an outer air outlet 10 are opened downwardly in the upper part on the front side of the case body 1 so as to be connected to the inner duct 5 and the outer duct 6, and the case body 1 is opposed to the air outlet. A suction port 11 is opened in the lower part on the front side. Reference numeral 12 denotes a canopy that protrudes forward from the top of the case body 1, and the operation / display unit 13 is arranged on the front surface of the canopy unit 12 so that the operation / display unit 13 can be seen from the front surface.

  Reference numeral 14 denotes a fluorescent lamp for illuminating the inside of the cabinet and the front portion, and is disposed on the lower surface of the commodity display shelf 3 and the canopy 12 portion.

  Further, a blower fan (not shown) is also arranged in the outer duct 6.

  In the above configuration, the inner duct 5 is operated by operating the cooler 7 and the blower fan 8 during the cold-retaining operation in which the refrigerant is circulated together with the compressor, the condenser, and the expansion valve (not shown) to keep the product in the product display room cold. A low-temperature cold airflow that exchanges heat with the cooler 7 circulates uncooled air through the outer duct 6, and the front opening of the case body 1 from the inner air outlet 9 and the outer air outlet 10 toward the inlet 11. The two-layered air curtain is blown out and formed to cool the product displayed on the product display shelf 3 in the warehouse.

  As shown in the schematic enlarged front view of FIG. 2, the operation / display unit 13 includes an operation unit 131 and a display 132. The operation unit 131 includes an up key 131a, a down key 131b, a lighting switch 131c, and a determination switch. 131d.

  The display 132 displays the current temperature, data at the time of setting or confirmation.

  The up key 131a and the down key 131b are keys for increasing / decreasing numerical values in order to change the data displayed on the display 132 at the time of setting.

  The illumination switch 131 c is a switch for switching on / off of the fluorescent lamp 14.

  The determination switch 131d is a switch that is operated when setting items, determining input data, and the like regarding switching of display items, switching to a setting mode, and switched setting items.

  Next, FIG. 3 shows a control block diagram of the showcase, and 30 is a microcomputer controller that controls the showcase as a whole.

  The microcomputer controller 30 includes a ROM (Read Only Memory) 31 for storing a program, a RAM (Random Access Memory) 32, and an EEPROM (Electrically Erasable and Programmable Read Only Memory) 33 for storing various setting values. Various sensors 34 arranged at predetermined positions of the showcase body 1, such as a temperature sensor, an internal temperature display sensor, a defrosting temperature sensor, and an outside air temperature sensor, display the operating state and internal set values of the showcase, In addition to the operation / display unit 13 for changing the set value and switching the operation mode, for example, an electromagnetic valve or a fan (not shown) is connected.

  The operation unit 131 of the operation / display unit 13 can perform various settings by switch operations at the time of factory shipment, at the time of delivery into the store, or after delivery to the store, and the display unit 132 is usually appealing to shoppers. Therefore, the operating temperature can be displayed, and each setting data can be displayed when setting and checking.

  In this configuration, a display example will be described using the display sequence diagram of FIG.

  The EEPROM 33 stores in advance three display items as the first display group: the current internal temperature, the operation status such as during operation or failure, and the alarm status that is generated such as a high temperature alarm. Three display items are stored as display groups: the chamber temperature setting value, the alarm temperature setting value for generating a high temperature alarm, and the fan rotation speed, and which one of the first and second display groups is stored. Whether to display on the display unit 132 at normal time is set.

  Here, as shown in FIG. 4, the first display group is displayed in the normal state, and the current internal temperature is displayed on the display 132 for a certain period of time (S01). When the internal temperature is displayed for a certain time, the operation status is then displayed on the display 132 for a certain time (S02). When the operation status is displayed for a certain time, the alarm status is then displayed on the display 132 for a certain time (S03). When the alarm status is displayed for a certain time, the display returns to the current internal temperature display in S01.

  In this way, a plurality of display items set in the same display group are switched and displayed at regular intervals.

  As for the alarm status display in S03, if there is no alarm, the alarm status display may be blank, or the alarm status display may be skipped to return to the internal temperature display in S01.

  Switching from the first display group to the second display group is performed by pressing the enter switch 132d, and the internal set temperature, which is the display item of the second display group, is displayed on the display 132 for a certain period of time ( S11). If the internal set temperature is displayed for a certain time, the alarm temperature set value is then displayed on the display 132 for a certain time (S12). When the alarm temperature set value is displayed for a certain time, the fan rotation speed is then displayed on the display 132 for a certain time (S13). When the fan rotation speed is displayed for a certain period of time, the temperature returns to the set temperature in S11.

  Thus, the display group displayed on the display device 132 can be switched every time the determination switch 132d is pressed, and useful information for the user or the store side administrator can be displayed without increasing the size of the display device.

  Regarding the display on the display 132 at normal time, during normal operation, only the current internal temperature is displayed on the display 132, and the store side administrator displays the first display group by pressing the enter switch 131d. Then, by operating the up key 131a or the down key 131b, the display group may be switched, and the settlement switch 131d may be pressed again to return to the current internal temperature display. Since a certain user can only display the internal temperature, the user is not confused by the switching of the display.

  The display group is not limited to two groups, and is not limited to the three display items, and can be set or changed separately. Further, the group that is normally displayed is the first group. However, the present invention is not limited to this, and a group that is normally displayed may be set.

  Next, a display example according to another embodiment will be described with reference to FIG.

  First, in a state where the internal temperature “5 ° C.” is displayed (S21), the setting mode is switched using the operation unit 131, and the internal temperature setting is read using the up key 131a and the down key 131b. When the determination switch 131d is pressed, the internal temperature is set. When the up key 131a and the down key 131b are operated to input a new internal set temperature “3 ° C.” from the current set temperature and the enter switch 131d is pressed, the setting is confirmed and stored in the EEPROM 33.

  Next, when the high temperature alarm temperature setting is read with the up key 131a and the down key 131b and the determination switch 131d is pressed, the high temperature alarm temperature setting is set. Here, when the up key 131 a and the down key 131 b are operated to input a new alarm temperature set value “28 ° C.” and the determination switch 131 d is pressed, the setting is confirmed and stored in the EEPROM 33.

  Next, when the high temperature alarm time setting is read with the up key 131a and the down key 131b and the decision switch 131d is pressed, the high temperature alarm time setting is made. Here, when a time “20 minutes” for detecting a new high temperature alarm is input by operating the up key 131 a and the down key 131 b and the determination switch 131 d is pressed, the setting is confirmed and stored in the EEPROM 33.

  Here, when the determination switch 131d is pressed again, as shown in S31 to S33 in FIG. 5, only the three setting items whose settings have been changed are displayed by switching the items set every “2 seconds”, for example.

  Next, when the determination switch 131d is pressed again, the normal display mode is restored.

  As described above, in FIG. 5, only the item whose setting has been changed can be switched and displayed on the display unit 132 at a constant period, so that the confirmation work at the time of setting is facilitated.

  Further, instead of the operation of the determination switch 131d, when the setting item is displayed on the display 132 for one to several times or for a predetermined time, the normal display mode may be restored.

  In addition, although the open showcase was taken as an example as the above object, various types of showcases such as a showcase with a door and a warm storage showcase can be used as long as the operation / display unit 13 is provided.
