Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a showcase installed in a store such as a supermarket, or a convenience store. [0003] 2. Description of Related Art [0004] A conventional showcase of this kind is known which has a showcase body having openings at its front side, rear side and left or right side, a commodity storage section provided in the showcase body, a bottom-side air passage formed along the bottom side of the commodity storage section, a side air passage formed along the other side of the commodity storage section, a commodity cooling air passage so as to branch off from the side air passage and extend toward the other side, and a cooler as well as a blower provided in a bottom-side air passage so as to cool the air flowing in from air inlets provided along the bottom of each of the openings of the showcase body to the bottom-side air passage and let it flow out from air outlets provided in each opening side of the commodity cooling air passage to cool the commodity storage section. [0005] Since the above described showcase having openings at its front side, rear side and left or right side, the states of temperature as well as moisture of the air outside the commodity storage section entering the commodity storage section may differ depending on the respective openings. Since the bottom-side air passage is provided with coolers brought into connection in parallel to a refrigerant circulation at its front side and rear side or each opening, different frost formation amount for the coolers could result in occurrence of difference in cooling performance. In case of defrosting operation, each cooler is different in the frost formation amount and therefore could make sure defrosting controls on the coolers complicated. SUMMARY OF THE INVENTION [0006] An object of the present invention is to provide a showcase capable of retaining stable cooling performance also in the case where the states of temperature as well as moisture of the air outside a commodity storage section entering the commodity storage section from the respective openings differ. [0007] To achieve the above-described object, according to the present invention, there is provided a showcase including a showcase body having openings in at least two of its front side, rear side and left and right sides, a commodity storage section provided in the showcase body, a bottom-side air passage having an air inlet along a lower end of each of the openings, a side air passage extending upward along one side of the commodity storage section from the bottom-side air passage, a commodity cooling air passage formed so as to extending from the side air passage toward the other side, having air outlets in each of the openings sides, a blower for causing air to flow from each of the air inlet into the bottom-side air passage, a cooler provided inside the bottom-side air passage for cooling the air flowing into the bottom-side air passage, and a air guiding section for guiding the air flowing from each of the air inlet to the bottom-side air passage to the air inflowing side of the cooler. [0008] This guides the air flowing in from respective air inlets to the air inflowing side of the cooler and therefore a cooling apparatus in a simple structure having one cooler cools the commodity storage section. This arrangement enables the commodity storage section to be cooled with a cooling apparatus in a simple structure having one cooler and thereby enables temperature control as well as defrosting control to be implemented easily. Also in the case where the state of temperature or moisture of the air outside entering the commodity storage section from respective openings is different, no difference in the frost formation amount will occur as in case of providing a plurality of coolers, but stable cooling performance can be retained. [0009] The above-described and other objects, features and advantages of the present invention will become apparent from the following detailed description of the invention with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0010] FIG. 1 is a perspective view of the whole of a showcase which represents an embodiment of the present invention; [0011] FIG. 2 is a sectional front view of the showcase; [0012] FIG. 3 is a sectional side view of the showcase; [0013] FIG. 4 is a sectional plan view of the showcase showing a partition plate; [0014] FIG. 5 is a plan view of the showcase showing a drain pan; [0015] FIG. 6 is a plan view of the essential portion of the showcase showing a manifold; [0016] FIG. 7 is a perspective view of the essential portion of a cooler; and [0017] FIG. 8 is a plan view of the essential portion of the cooler. DESCRIPTION OF THE PREFERRED EMBODIMENTS [0018] This showcase has a showcase body 10 having openings at its front side, rear side and left or right side, and an air passage 20 formed in the showcase body 10. [0019] The showcase body 10 has a lower case 11 in the form of a box opened at its top, a ceiling plate 12 provided as a top cover, and a side plate 13 provided as a left or right side cover. [0020] The lower case 11 is formed by heat insulating walls 11a at its front, rear and bottom sides and right or left side and by the side plate 13 at the left or right side. The top opening of the lower case 11 is covered with a bottom plate 11b placed at a distance from a bottom surface in the lower case 11 formed by the heat insulating wall 11a. Glass plates 11c are provided on upper-end peripheral portions of the lower case 11 except at the side plate 13 side so as to extend upward so that the bottom plate 11b is visible in a sideway direction from the outside. A machine chamber lid is provided under the lower case 11. Pieces of refrigeration equipment such as a compressor, a condenser and a condenser blower (not shown) are housed in the machine chamber 11d. Continue reading about Showcase...
