The interior lighting lamp is mainly used for illuminating a commodity displayed in the commodity display room, and various structures are known as mounting structures for the interior lighting lamp (for example, Patent Document 1 below). 2).

JP-A-8-224150 Japanese Patent Laid-Open No. 8-56792

  However, in the reach-in showcase described in Patent Documents 1 and 2 described above, the illumination on the outside of the reach-in showcase (for example, the passage on the front side of the reach-in showcase, the exterior panel of the reach-in showcase, etc.) A lamp is used, and the outside of the reach-in showcase is illuminated by light emitted from the interior illumination lamp and transmitted through the glass door. For this reason, compared with the open showcase of a type which does not have a glass door, the illumination intensity of the outside of a reach-in showcase is low.

  In recent years, reach-in showcases using LEDs as interior lighting have become widespread. The LED has strong directivity, and the irradiation direction of the LED is directed to the product display room. For this reason, when LED is used as the interior illumination lamp, light transmitted through the glass door is less than when a fluorescent lamp is used as the interior illumination lamp, and the illuminance on the outside of the reach-in showcase is further increased. It is even lower.

  In order to increase the illuminance outside the reach of the reach-in showcase due to the light emitted from the interior illumination lamp, it is conceivable to increase the luminous intensity of the interior illumination lamp. However, increasing the brightness of the interior lighting increases the amount of heat generated from the interior lighting and heats the cool air circulating in the product display room. It will reduce the thermal efficiency of production.

  The present invention has been made in order to solve such problems, and its purpose is to increase the illuminance outside the reach of the reach-in showcase and to circulate the product display room by heat from the interior lighting. It is an object of the present invention to provide a reach-in showcase capable of suppressing the warming of the cold air and increasing the thermal efficiency related to the generation of the cold air.

A reach-in showcase according to the present invention includes a showcase main body having an opening formed on the front surface and a product display chamber formed therein, a transparent door body capable of opening and closing the opening, and an inner side of the transparent door body. In the cool air circulation type reach-in showcase having an interior lamp disposed in the commodity display room, the exterior lamp mounted on the showcase body and disposed outside the transparent door body, And a human sensor for detecting the presence or absence of a person near the reach-in showcase, and the outside lighting is always lit during the business hours of the store where the reach-in showcase is installed, The illuminating lamp is provided so that the luminous intensity can be switched up and down, and when the human sensor detects a person in the vicinity of the showcase, the luminous intensity can be increased. Said reduced in intensity in the case of a person who is near the showcase is not detected, the outside-compartment lamp is provided a light intensity capable raising and lowering switching the in-compartment in response to the detection result of the human sensor When the illuminating lamp is raised in luminous intensity, the luminous intensity is lowered .

  Further, in the reach-in showcase according to the present invention described above, the illuminance value on the outside of the reach-in showcase can be kept constant by switching the luminous intensity between the interior-light and the exterior-light. It is desirable to be performed.

According to the reach-in showcase according to the present invention, during the store operation, since the outside transparent lamp attached to the showcase body and arranged outside the transparent door body is always lit, the luminous intensity of the interior lighting lamp The illuminance on the outside of the reach-in showcase can be increased without increasing the height. Furthermore, the interior lighting can be increased when the presence sensor detects a person near the reach-in showcase, and the presence sensor does not detect a person near the reach-in showcase. In some cases, the luminous intensity can be lowered, so that when there is a person near the reach-in showcase, it is possible to make the commodity in the commodity display room easier to see by raising the luminous intensity of the interior lighting. On the other hand, when there is no person near the reach-in showcase and there is no need to illuminate the product in the product display room, the amount of heat generated from the interior lighting lamp is reduced by reducing the intensity of the interior lighting lamp, It is possible to suppress the warming of the cool air circulating in the product display room by the heat from the interior lighting lamp, and to increase the thermal efficiency related to the generation of the cool air. Also, when the brightness of the interior lighting is increased according to the detection result of the human sensor, the brightness of the exterior lighting is lowered, so the reach-in show with the interior lighting and the exterior lighting is reduced. While ensuring the illuminance on the outside of the case, reducing the luminous intensity of the outside illumination lamp can suppress the power consumption of the outside illumination lamp and save energy.

  In addition, since the illuminance value on the outside of the reach-in showcase is maintained at a constant level, the brightness increase / decrease switching between the interior lighting and the exterior lighting is performed so that the illumination environment outside the reach-in showcase Can be kept constant.

It is a section side view showing the reach-in showcase of one embodiment of the present invention. It is a block diagram which shows the electrical connection structure of the component regarding illumination. It is a flowchart explaining lighting control of the interior illumination lamp and the exterior illumination lamp.

  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional side view showing a reach-in showcase 1. The reach-in showcase 1 has a box-shaped showcase body 4 in which an opening 2 is formed on the front surface and a product display chamber 3 is formed inside. A glass door 5, which is a transparent door body capable of opening and closing the opening 2, is attached to the showcase body 4.

  The showcase body 4 has an outer peripheral wall 6 formed of a heat insulating material and a partition wall 7 positioned inside the outer peripheral wall 6, and a region surrounded by the partition wall 7 in the showcase body 4 is a product display. It is chamber 3. A plurality of product display shelves 8 for displaying products are arranged in the product display room 3 in the vertical direction.

  A duct 9 is formed between the outer peripheral wall 6 and the partition wall 7. Housed in the duct 9 are a blower fan 10 that circulates air in the showcase body 4 through the duct 9 and a cooler 11 that cools the air blown by the blower fan 10 and generates cool air. . An air outlet 12 that opens downward is formed at the tip of the opening 9 on the top of the duct 9, and a suction port 13 that opens upward is formed at the tip of the opening 2 on the bottom of the duct 9. Yes. The cool air blown by the blower fan 10 and generated by the cooler 11 is blown downward from the air outlet 12 and sucked from the air inlet 13, and an air curtain of cold air is formed between the air outlet 12 and the air inlet 13. It has become so.

  The showcase body 4 is provided with an interior lamp 14 disposed in the product display room 3 inside the glass door 5. The interior illumination lamp 14 is arranged in a direction extending in the vertical direction. Moreover, the interior lighting lamp 14 is provided so that the luminous intensity can be increased and decreased. The light emitted from the interior illumination lamp 14 illuminates the product displayed on the product display shelf 8, and a part of the light passes through the glass door 5 to the outside of the reach-in showcase 1 (for example, The passage 15 on the front side of the reach-in showcase 1, the exterior panel 16 of the reach-in showcase 1, etc.) are illuminated.

  A canopy 17 that is disposed outside the glass door 5 and extends in the horizontal direction along the lateral width direction of the showcase body 4 is attached to the upper portion of the showcase body 4. Below the canopy 17, an outside illumination lamp 18 extending in the horizontal direction along the lateral width direction of the showcase body 4 is attached. The outside illumination lamp 18 is always lit during the business hours of the store where the reach-in showcase 1 is installed. Moreover, the exterior lighting lamp 18 is provided so that the luminous intensity can be increased and decreased. The light emitted from the outside illumination lamp 18 illuminates the outside of the reach-in showcase 1 (for example, the passage 15 on the front side of the reach-in showcase 1, the exterior panel 16 of the reach-in showcase 1). Yes.

  FIG. 2 is a block diagram showing an electrical connection structure of components related to the illumination of the reach-in showcase 1. The reach-in showcase 1 is provided with a control unit 19 that controls each part of the reach-in showcase 1. The control unit 19 includes an interior illumination lamp 14, an exterior illumination lamp 18, a human sensor 20, and the like. A control panel 21 having a timer function is connected. The human sensor 20 is a sensor that detects the presence or absence of a person near the reach-in showcase 1 and is attached to the showcase body 4 or the ceiling portion of the place where the reach-in showcase 1 is installed. . The control panel 21 is a part for performing various settings related to the control of the reach-in showcase 1, for example, a store opening time or closing time, a value for switching up or down the luminous intensity of the interior lighting lamp 14 or the exterior lighting lamp 18, etc. Can be set.

  FIG. 3 is a flowchart for explaining lighting control of the interior illumination lamp 14 and the exterior illumination lamp 18. First, it is determined whether or not the store opening time has come (step S1).

  When the store opening time is reached (YES in step S1), the interior illumination lamp 14 is turned on in a low light intensity state (step S2), and the exterior illumination lamp 18 is illuminated in a high light intensity state (step S3). .

  After the interior illumination lamp 14 and the exterior illumination lamp 18 are turned on, it is determined whether or not the store closing time has come (step S4). When the store closing time is reached (YES in step S4), the interior illumination lamp 14 is turned off (step S5), the exterior illumination lamp 18 is turned off (step S6), and the process returns to step S1.

  On the other hand, if it is not the closing time (NO in step S4), it is determined whether or not the human sensor 20 detects that there is a person near the reach-in showcase 1 (step S7). When it is not detected that there is a person near the reach-in showcase 1 (NO in step S7), the process returns to step S4.

  On the other hand, if it is detected that there is a person near the reach-in showcase 1 (YES in step S7), the intensity of the interior lamp 14 is switched to a high intensity (step S8), and further, the exterior illumination lamp The light intensity of 18 is switched to a low light intensity (step S9).

  After the light intensity switching between the interior illumination lamp 14 and the exterior illumination lamp 18 is performed, it is determined whether or not the human sensor 20 has finished detecting the person (step S10). When the human sensor 20 continues to detect a person (NO in step S10), the process returns to step S4.

  On the other hand, when the human sensor 20 completes the detection of the person (YES in step S10), the light intensity of the interior illumination lamp 14 is switched to a low intensity (step S11), and further, the intensity of the exterior illumination lamp 18 Is switched to high luminous intensity (step S12), and the process returns to step S4.

  Here, switching of the light intensity between the interior illumination lamp 14 and the exterior illumination lamp 18 based on the detection result of the human sensor 20 is such that the interior illumination lamp 14 is turned on at a low intensity and the exterior illumination lamp 18 is high. The illuminance outside the reach of the reach-in showcase 1 when it is turned on at a light intensity, and the reach-in showcase 1 when the interior light 14 is turned on at a high light intensity and the outside light 18 is turned on at a low light intensity. The illuminance on the outside of the warehouse is kept constant.

  In addition, although switching of the light intensity of the interior lighting lamp 14 to low light intensity and high light intensity was demonstrated, as an example of low light intensity, a light extinction state is also included.

  In such a configuration, in the reach-in showcase 1, when the blower fan 10 is driven and the cooler 11 is driven, the air blown through the duct 9 is cooled by the cooler 11 to become cool air, The cold air blows out from the air outlet 12 and is sucked in from the air inlet 13 and enters the duct 9, and is cooled again by the cooler 11. In this way, the cool air cooled by the cooler 11 circulates in the product display chamber 3 so that the product displayed on the product display shelf 8 is cooled.

  When the interior illumination lamp 14 is turned on, a part of the light emitted from the interior illumination lamp 14 is transmitted through the glass door 5 to the outside of the reach-in showcase 1 (for example, the front side of the reach-in showcase 1). The passage 15 and the exterior panel 16 of the reach-in showcase 1 are illuminated. When the outside illumination lamp 18 is turned on, the light emitted from the outside illumination lamp 18 illuminates the outside of the reach-in showcase 1.

  Here, the outside lighting lamp 18 is always lit during the business hours of the store, and always illuminates the outside of the reach-in showcase 1. Therefore, the illuminance outside the reach-in showcase 1 can be increased without increasing the luminous intensity of the interior illumination lamp 14, and the surroundings of the reach-in showcase 1 can be prevented from becoming dark.

  The interior illumination lamp 14 can reduce the light intensity when the human sensor 20 has not detected a person near the reach-in showcase 1, and the human sensor 20 can detect a person near the reach-in showcase 1. If you are, the brightness is raised. For this reason, when there is a person near the reach-in showcase 1, the product in the product display room 3 can be well illuminated by increasing the luminous intensity of the interior lamp 14, and the vicinity of the reach-in showcase 1. It is possible to make it easy to see the products in the product display room 3 for those who are in the area. On the other hand, when there is no person near the reach-in showcase 1 and it is not necessary to illuminate the product in the product display room 3, the heat generated from the interior illumination lamp 14 is reduced by reducing the intensity of the interior illumination lamp 14. It is possible to increase the thermal efficiency related to the generation of cool air by reducing the amount and suppressing the warm air that circulates in the product display chamber 3 by the heat from the interior lamp 14.

  Moreover, when the luminous intensity of the interior illumination lamp 14 is increased based on the detection result of the person near the reach-in showcase 1, the luminous intensity of the exterior illumination lamp 18 is decreased. Since the illuminance of the outside of the reach-in showcase 1 due to the light emitted from the interior illumination lamp 14 increases as the luminous intensity of the interior illumination lamp 14 increases, the reach-in show even if the intensity of the exterior illumination lamp 18 is lowered. The illuminance outside the case 1 can be maintained. And the energy consumption can be aimed at by suppressing the power consumption in the exterior illumination lamp 18 by reducing the luminous intensity of the exterior illumination lamp 18.

  Further, when the luminous intensity of the interior illumination lamp 14 and the exterior illumination lamp 18 is switched up and down based on the detection result of the human sensor 20, the illumination switching on the outside of the reach-in showcase 1 is constant. Since it is performed to be maintained, the illuminance environment on the outside of the reach-in showcase 1 can be maintained constant.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, some constituent elements may be deleted from all the constituent elements shown in the above-described embodiments, and the constituent elements according to different embodiments may be appropriately combined.
