Description

  The present invention relates to a refrigerated showcase that is used by being installed on a counter of a restaurant such as a sushi restaurant or a cooked rice in order to store various fresh ingredients such as sushi ingredients at a low temperature.

  A refrigerated showcase called a so-called “netacase” is installed at counters of restaurants such as sushi restaurants and Kappo. As such a refrigerated showcase, a storage room is formed in a heat insulating wall having a transparent wall on the front surface and the upper surface, a machine room is formed on the side of the heat insulating wall, and in the bottom wall and the rear wall of the heat insulating wall. Some have a cooler and the transparent wall on the upper surface of the heat insulating wall is a door that can be opened and closed (see, for example, Patent Document 1).

  In addition, a machine room for installing a refrigeration cycle is disposed on the lower surface side of the display room whose front surface is glazed, and a cold air passage is provided in the upper part of the display room and the lower part of the display room (see, for example, Patent Document 2) )), Or a cooler disposed on the upper side of the display room whose front surface, upper surface and rear surface are glass-lined and on the back side of the bottom surface of the display room (for example, see Patent Document 3).

JP-A-6-117745 (page 3-5, FIG. 2) Japanese Patent Laid-Open No. 11-63767 (page 3-6, FIG. 1) JP 2003-111650 A (page 2-5, FIG. 1)

  In the case of the refrigerated showcase described in Patent Document 1, since the cooler is arranged in the bottom wall and the rear wall of the heat insulating wall, the rear wall is high to secure the cooler arrangement space. It tends to be. For this reason, a feeling of pressure is often given to the eating and drinking seated at the counter, and it is often difficult to put in and out the refrigerated goods.

  Further, in the case of the refrigerated showcase described in Patent Documents 2 and 3, since the cold air passage or the cooling pipe is arranged above the display room, the visibility of the refrigerated object is deteriorated, or the effective space of the display room Or inviting a reduction. In addition, in order to secure a wide effective space in the display room after arranging the cold air passage and the cooling pipe, it is necessary to raise the display room. Refrigerated items are difficult to put in and out.

  Furthermore, in the case of the refrigerated showcases described in Patent Documents 1 to 3, since the humidity in the display room is relatively low, the refrigerated material housed in the display room tends to dry. For this reason, the refrigerated material in the display room may lose moisture with the passage of the storage time, and the freshness and flavor may decrease.

  The problem to be solved by the present invention is to provide a refrigerated showcase in which the stored refrigerated product is easy to see, the refrigerated product is easy to put in and out, and the chilled product has little feeling of pressure and is excellent in the function of maintaining the freshness of the refrigerated product There is to do.

  In the refrigerated showcase of the present invention, a display room for storing refrigerated goods and a machine room containing a cooling device for cooling the display room are arranged in parallel in the horizontal direction, and at least the front of the display room, A transparent front cover covering a region including a boundary with the upper surface; an icing surface provided on the upper surface of the bottom of the display chamber; a cooling pipe extending from the cooling device and piped to the lower surface of the bottom; and A water supply port and a water discharge port provided, and a transparent opening / closing door that closes an opening formed on the back surface of the display room so as to be openable and closable. Here, the icing surface refers to a surface on which ice is formed on the upper surface by operating the cooling device.

  With such a configuration, since the area including at least the front and upper boundary of the display room is covered with the transparent front cover, the refrigerated material contained in the display room is easy to see and the door is opened. Since the opening on the back side opens, it is easy to put in and out the refrigerated product. In addition, the water supplied from the water supply port at the bottom of the display room can be washed while being sprinkled into the display room, and the drainage after washing can be discharged from the water discharge port, so that cleaning is easy. Further, the display room and the machine room are arranged in parallel in the horizontal direction, and it is not necessary to provide a cool air passage or a cooling pipe in the display room, so that the height of the display room is suppressed and the feeling of pressure is reduced. Moreover, as a result of forming ice on the icing surface at the bottom of the display room and cooling the display room, the humidity in the display room is kept constant, and the refrigerated product can be prevented from drying, so that the freshness of the refrigerated product is maintained well. Can do. If ice is formed on the icing surface using water supplied from the water supply port to the upper surface of the bottom, ice can be formed easily in a relatively short time.

  Here, if a buffer member having a plurality of through holes is laid on the upper surface of the icing surface, it becomes possible to place a refrigerated object on the buffer member, so that the ice formed on the icing surface is refrigerated. An object can be prevented from adhering. Further, since the water vapor sublimated from the ice on the frozen surface can evaporate upward through the plurality of through holes, the refrigerated material placed on the buffer member is not overdried.

  On the other hand, it is desirable to arrange a lighting fixture for illuminating the display room outside the display room. As a result, it is possible to brightly illuminate the refrigerated objects in the display room, thereby increasing the display effect and improving the cleanliness, and avoiding a decrease in cooling efficiency due to heat generated by the lighting fixture.

  In addition, if a temperature display unit for displaying the temperature in the display room is provided outside the machine room or the display room, the temperature in the display room can be always recognized, so that the storage state of the refrigerated object can be accurately grasped. it can.

  Furthermore, if a detachable opening / closing door is provided in at least a part of the area from the front to the upper surface of the machine room, it is easy to perform maintenance and inspection / repair work in the machine room. In addition, if an open / close door is provided on the upper surface of the machine room, the closed state can be maintained by the dead weight of the open / close door, so that it is not necessary to provide a lock mechanism, and the structure can be simplified.

  The present invention has the following effects.

  Hereinafter, a refrigerated showcase according to an embodiment of the present invention will be described with reference to the drawings. 1 is a front perspective view showing a refrigerated showcase according to an embodiment of the present invention, FIG. 2 is a rear perspective view of the refrigerated showcase shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along line AA in FIG. is there.

  As shown in FIG. 1 to FIG. 3, the refrigerated showcase 10 of the present embodiment has an appearance in which a plan view shape, a front view shape, and a back view shape are horizontally long rectangles, respectively, for accommodating refrigerated items. The display room 1 and the machine room 2 containing a cooling device (not shown) for cooling the inside of the display room 1 are arranged in parallel in the horizontal direction. The display room 1 and the machine room 2 are partitioned by a partition wall 3 having heat insulation properties.

  On the back of the machine room 2, a cooling switch 12 for turning on / off the cooling device, a lighting switch 13 for turning on / off the lighting fixture 16, and a water supply switch 17 for opening / closing the electromagnetic opening / closing valve 28, A temperature setting switch 14 for setting the cooling temperature in the display room R, a temperature display unit 15 for indicating the set temperature during operation of the temperature setting switch 14, and normally displaying the temperature in the display room R numerically, Is arranged. Further, on the upper surface of the machine room 2, a flat opening / closing door 2a for opening and closing a region including the front to the upper surface is detachably attached, and the opening / closing door 7 is detachable on the right side surface of the machine room 2. It is attached to.

  In order to supply power to a cooling device or the like built in the machine room 2, a power cord 20 extends from the back of the machine room 2, and if the power cord 20 is connected to a power source of AC 100 V (or AC 200 V), the refrigerated showcase 10 Can be activated. Rubber grounding members 8 are disposed at the four corners of the bottom of the refrigerated showcase 10. The cooling device in the machine room 2 is provided with a plurality of cooling fans (not shown) to improve the cooling function.

  The area including the boundary between the front surface and the top surface of the display chamber 1 is covered with a transparent front cover 4 having a smooth “<”-shaped curved surface, and a stainless steel plate is formed on the bottom surface of the inside R of the display chamber 1 and the rear of the top surface. A bottom member 19 and a top member 29 are disposed. On the lower surface of the bottom surface member 19 and the upper surface of the upper surface member 29, a cooling pipe 18 extending from the cooling device in the machine room 2 is piped. A groove 34 that extends linearly in the left-right direction is provided in a portion near the front surface of the bottom member 19, and a water supply port 24 is opened in a portion near the machine room 2 of the groove 34, near the end on the opposite side. Has a drain 33 opened. The water supply port 24 is screwed with a bowl-shaped water supply tool 25 having a water supply hole 25a on the outer periphery.

  Below the water supply port 24, a water supply pipe 5 piped in the back direction through the lower surface of the display chamber 1 is connected, and an electromagnetic opening / closing valve 28 is disposed in the middle of the water supply pipe 5. If the water supply pipe 5 is connected to an existing water pipe (not shown) or the like, water supply to the water supply port 24 can be performed. Since the drain pipe 6 piped in the back direction through the lower surface of the display chamber 1 is connected to the lower side of the drain port 33, the water flowing into the drain port 33 is passed through the drain pipe 6, It can be discharged to a predetermined drainage route.

  When the cooling device is operated, the bottom surface member 19 and the top surface member 29 are cooled by the cooling pipe 18, whereby the inside R of the display chamber 1 is cooled to the installation temperature. Further, the bottom surface member 19 is cooled below the freezing point by the cooling pipe 18, so that the upper surface becomes an icing surface, and ice 22 is formed on the upper surface. And if the plate-shaped buffer member 21 which has many through-holes 21a is mounted in the upper surface of the ice 22, the refrigeration thing 23 which is a storage object can be displayed side by side on it. Four opening / closing doors 9a slidable in the left-right direction are arranged in the opening 9 on the back surface of the display chamber 1, and the opening 9 is opened by sliding any of the opening / closing doors 9a.

  A partition member 30 made of stainless steel plate is arranged so that the upper portion of the display chamber 1 near the back surface is substantially flush with the rear edge portion 4a of the front cover 4, and a portion near the rear edge portion 4a of the front cover 4 is arranged. A light shielding cover 32 made of a stainless steel plate is detachably provided. The light shielding cover 32 is provided with a light shielding portion 31 that hangs down toward the front cover 4 at the front edge portion, and a plurality of through holes 11 are formed at the rear edge portion. The light shielding cover 32 is fixed by detachably locking a hook 35 provided on the lower surface of the rear edge portion to the locking member 36.

  The luminaire 16 is disposed in a space surrounded by the light shielding cover 32, the front cover 4, and the partition member 30, and light from the luminaire 16 passes through the rear edge 4a of the transparent front cover 4 through the inside R of the display chamber 1. It comes to light up. Further, a partition member 30 partitions the lighting fixture 16 and the cooling pipe 18 on the upper surface member 29. It is desirable that the space S1 above the top member 29 and the space S2 below the bottom member 19 are filled with a heat insulating material (not shown).

  Here, the use state of the refrigerated showcase 10 will be described with reference to FIG. The refrigerated showcase 10 is placed in an appropriate place on the counter of a restaurant such as a sushi restaurant or Kappo, and can be used by connecting the power cord 20 to a commercial power source. In this case, although it does not directly affect the cooling function itself, it is desirable to connect the water supply pipe 5 to the water pipe and connect the drain pipe 6 to a predetermined drain path. Thereafter, when the cooling switch 12 disposed on the back surface of the machine room 2 shown in FIG. 2 is turned on, the cooling device starts to operate, and when the lighting switch 13 is turned on, the lighting fixture 16 is turned on.

  After the cooling switch 12 is turned on, the temperature setting switch 14 is operated to set the temperature of the inside R of the display chamber 1. At this time, since the set temperature is displayed numerically on the temperature display unit 15, it is set to be below the freezing point. When the temperature setting is finished, when the electromagnetic switch 28 is opened by operating the water supply switch 17 on the back of the machine room 2, water is discharged from the water supply hole 25 a of the water supply device 25, and this water overflows from the groove 34. When the depth of about 5 mm is accumulated on the upper surface of the bottom member 19, the water supply switch 17 is operated again to stop water supply. In addition, the depth of water can be arbitrarily set as needed. Thereafter, the cooling device is continuously operated until the inside R of the display chamber 1 reaches the set temperature, and after reaching the set temperature, it is automatically controlled to keep the temperature. Further, the temperature of the inside R of the display chamber 1 during operation is displayed on the temperature display unit 15.

  When the temperature of the bottom member 19 reaches a set temperature (below freezing point), the accumulated water gradually freezes, and layered ice 22 is formed on the top surface of the bottom member 19. If the buffer member 21 is placed on the upper surface of the ice 22 by opening the 9a, the refrigerated objects 23 can be displayed side by side. Since the temperature of the inside R of the display chamber 1 is automatically controlled to the set temperature, the refrigerator 23 can be stored at a low temperature.

  The inside R of the display chamber 1 is excellent because it is cooled by the cooling pipe 18 on the lower surface of the bottom member 19, the layered ice 22 formed on the entire upper surface of the bottom member 19, and the cooling pipe 18 on the upper surface of the upper member 29. Exhibits the cooling function. Even in the state in which the ice 22 is formed, the water in the groove 34 is not frozen. Therefore, if the water supply switch 17 is operated and water is discharged from the water supply hole 25a in this state, a water layer is formed on the upper surface of the ice 22. (Not shown) can be formed. If the buffer member 21 is arranged on the water layer (not shown) formed in this way and the refrigerated object 23 is placed thereon, water vapor generated from the water layer (not shown) is obtained. Thus, a further excellent moisture retention function can be obtained.

  Further, since excess moisture in the display chamber 1 is condensed on the surface of the ice 22, the inner surface of the front cover 4 and the open / close door 9a is not clouded by condensation, and good transparency can be maintained. Further, since water vapor sublimated from the ice 22 is supplied to the refrigerated product 23, the refrigerated product 23 is not overdried, and the freshness can be maintained for a long time. When the ice 22 is excessively formed, the ice 22 can be dissolved and removed by operating the cooling switch 12 to perform the defrosting operation. At this time, the water generated by the melting of the ice 22 can be discharged through the drain pipe 6 piped from the drain port 33 near the left end of the groove 34 toward the back. If an electromagnetic on-off valve (not shown) is provided in the middle of the drain pipe 6 and a drain switch (not shown) for opening / closing the drain pipe 6 is provided on the back of the machine room 2, the drain pipe 6 can be easily opened and closed. It can be carried out.

  Thus, the refrigerated showcase 10 is housed in the interior R of the display room 1 because the display room 1 has a box structure in which the area including the boundary between the front surface and the upper surface is covered with the transparent front cover 4. The refrigerated product 23 is easy to see from the outside, and when the opening / closing door 9a is opened, the rear surface of the display chamber 1 is opened, so that the refrigerated product 23 can be easily taken in and out.

  The display room 1 and the machine room 2 are arranged in parallel in the horizontal direction, and the inside R of the display room 1 is cooled by the cooling pipe 18 extended from the cooling device. There is no need to provide. For this reason, the height of the display room 1 can be suppressed, and a feeling of pressure is not given to the restaurant seated at the counter. Furthermore, since the plate-shaped buffer member 21 having a plurality of through holes 21 a is placed on the upper surface of the ice 22, it is possible to prevent the refrigerated object 23 from adhering to the ice 22.

  On the other hand, since the lighting fixture 16 for illuminating the inside R of the display room 1 is arranged in the portion near the upper back surface of the display room 1, the refrigerated object 23 accommodated in the inside R can be illuminated brightly, High display effect and excellent cleanliness. Moreover, since the lighting fixture 16 is covered with the light-shielding cover 32, glare is not given to the person who is on the front side of the refrigerated showcase 10. Furthermore, since the heat radiating through-hole 11 is opened in the light shielding cover 32 and the display chamber 1 is partitioned by the partition member 30, it is possible to avoid a decrease in cooling efficiency due to heat generation of the lighting fixture 16. . If an electronic bulletin board is provided in front of the machine room 2, various messages such as information on the refrigerated objects 23 stored in the display room 1 and store information can be displayed.

  Moreover, since the temperature display part 15 which displays the temperature in the display room 1 is arrange | positioned in the back surface of the machine room 2, the temperature in the display room 1 can always be visually recognized, and the preservation | save state of the refrigerated object 23 is correctly identified. I can grasp it. Furthermore, since the detachable doors 2a and 7 are detachably mounted in the machine room 2, the upper surface of the machine room 2 can be removed by removing the open / close doors 2a and 7 during maintenance, inspection and repair in the machine room 2. In addition, the right side surface can be opened widely, and the workability is good. Further, since the open / close door 2a can be kept closed by its own weight, it is not particularly necessary to provide a lock mechanism, and the structure can be simplified.

  On the other hand, as shown in FIG. 3, the LED sterilizer 38 is disposed at a position facing the rear end portion of the front cover 4, and light emitted from the LED sterilizer 38 passes through the front cover 4 and passes through the front cover 4. The refrigerator 23 is irradiated from the inner surface. For this reason, a sterilization effect can be exerted on the refrigerated product 23, which is effective for maintaining the freshness of the refrigerated product 23. Moreover, since the photocatalyst which has an antibacterial action is made to adhere also to the buffer member 21, the antibacterial effect with respect to the refrigerated thing 23 can be acquired.

  Next, with reference to FIG. 4, the cleaning method of the refrigerated showcase 10 is demonstrated. FIG. 4 is a cross-sectional view showing a cleaning state of the inside of the display chamber of the refrigerated showcase shown in FIG. When it is necessary to clean the inside R of the display room 1, as shown in FIG. 4, the water supply hose 27 connected to the shower device 38 is connected to the water supply port 24 after the water supply tool 25 (see FIG. 3) is removed. Are connected. After that, if the water supply switch 17 on the back of the machine room 2 is operated to open the electromagnetic opening / closing valve 28, it becomes possible to supply water to the water supply hose 27. Therefore, the opening / closing lever 38a of the shower device 38 is operated, Cleaning can be performed while sprinkling water from the tip of the shower device 38 to the inside R of the display chamber 1.

  The water sprayed from the shower device 38 and used for cleaning gathers in the groove 34 from the upper surface of the bottom member 19, flows into the drain port 33 (see FIG. 1), and then passes through the drain pipe 6 to a predetermined drainage path. Since it is discharged, waste water treatment is also easy.

  Although the refrigerated showcase 10 of this embodiment demonstrated the case where it uses in restaurants, such as a sushi restaurant and a Japanese cuisine, it is not limited to the use which refrigerately stores seafood, refrigerated storage of cakes etc. You can also
