  The present invention relates to a beverage dispenser that cools and supplies a beverage such as beer.

  Examples of this type of beverage dispenser include those shown in FIGS. This is because the cooling water tank 20 for cooling the beverage and the refrigeration apparatus 25 for cooling the cooling water tank 20 are accommodated in the housing 11, and the cooling fan 28 of the condenser 27 constituting the refrigeration apparatus 25 is driven to drive the inside of the housing 11. The air introduced from the lower intake port (not shown) is allowed to pass through the condenser 27 to be cooled, and the air passed through the condenser 27 is discharged to the upper exhaust port 17 of the peripheral walls 12 b and 14 of the housing 11. , 17a.

  As shown in FIGS. 6 and 7, the housing 11 has a housing main body 12 composed of a front panel 12a and left and right side panels 12b and 12b, a bottom plate 13 screwed to the lower side thereof, and a back surface thereof. The rear panel 14 and the ceiling plate 15 are fixed by screws. A flange portion 12c bent inward is formed on each upper edge portion of the front panel 12a and the left and right side panels 12b, 12b, and the ceiling plate 15 bent four sides downward is placed on the upper side of the housing body 12. The upper side of the housing 11 is closed by being supported on each flange portion 12c. Inside the housing 11, a cooling water tank 20 provided with a heat insulating material 20 a on the outer periphery and a main part of a refrigeration apparatus 25 for cooling the cooling water accommodated therein are arranged in the front and rear.

  As shown mainly in FIG. 7, a coiled evaporation pipe 22 that constitutes a part of the refrigeration apparatus 25 is provided upright inside the inner peripheral surface of the cooling water tank 20. A coiled beverage cooling pipe 21 is provided concentrically with the evaporation pipe 22 in the cooling water tank 20, and one end of the beverage cooling pipe 21 is connected to a beverage supply source (not shown) such as a beer barrel. The end is connected to the pouring cock 21a. An agitating motor 24a of an agitating device 24 is attached to the support plate 2 disposed on the upper surface of the cooling water tank 20. Cooling water is provided at the tip of a shaft 24b extending downward from the agitating motor 24a along the center line of the cooling water tank 20. A stirring blade 24c for agitating is fixed.

  The main part of the refrigeration apparatus 25 excluding the evaporation pipe 22 is composed of a compressor 26 provided at the rear part on the bottom plate 13 of the housing 11, and the lower and upper sides of the shelf 3 screwed and fixed to the rear middle stage in the housing 11. It is comprised by the condenser 27 and the cooling fan 28 which were attached to.

  The shelf 3 rises from the front edge along the rear surface of the heat insulating material 20a of the cooling water tank 20 and then extends forward along the upper surface of the cooling water tank 20 and the front of the stirring motor 24a. Thus, the shroud 4 is integrally formed of the partition plate portion 4c that rises vertically from the support plate portion 4b and reaches the ceiling plate 15. Between the shelf board 3 and the ceiling board 15, an exhaust space R <b> 1 is formed in which exhaust gas whose temperature has risen through the condenser 27 and the cooling fan 28 is discharged. The space between the cooling water tank 20 and the ceiling plate 15 is connected to the upper side of the cooling water tank 20 by the partition plate portion 4c of the shroud 4 and the space connected to the exhaust space R1. It is divided into. An electrical box (control device) 29 for controlling the operation of the refrigeration apparatus 25 is provided on the support plate portion 4b, and is located in a space communicating with the exhaust space R1. A large number of horizontally long exhaust ports 17 and 17a are formed by punching at the rear upper part of the left and right side panels 12b of the housing 11 and the upper part of the rear panel 14 forming the peripheral wall of the exhaust space R1, and are discharged into the exhaust space R1. The exhaust is discharged out of the housing 11 through the exhaust ports 17 and 17a.

  The refrigerant compressed by the compressor 26 of the refrigeration apparatus 25 is cooled and liquefied by the air introduced from the lower intake port (not shown) in the housing 11 by the cooling fan 28 when passing through the condenser 27, and becomes capillary Then, it is sent to the evaporation pipe 22 in the cooling water tank 20, vaporized to cool the cooling water, and then returned to the compressor 26. Thereby, the cooling water in the cooling water tank 20 is cooled, and a frozen ice layer is formed around the evaporation pipe 22. Beverages such as beer supplied from a beverage supply source are cooled by the cooling water in the cooling water tank 20 when passing through the beverage cooling pipe 21, and are poured out from the dispensing cock 21a into a container such as a glass.

  In such a conventional technique, as shown in FIG. 7, the exhaust whose temperature has risen by cooling the condenser 27 from the cooling fan 28 is exhausted upward into the exhaust space R <b> 1. Accordingly, as shown by an arrow L4, the gas flows in a direction substantially orthogonal to the side panels 12b and the back panel 14 and is discharged to the outside from the exhaust ports 17 and 17a.

  Further, when an electrical box (control device) 29 for controlling the operation of the refrigeration apparatus 25 is provided in a space communicating with the upper side of the cooling water tank 20, condensation is generated in the electrical box 29 by being cooled by the cold air from the cooling water tank 20. There is a risk that a malfunction may occur in the operation of the refrigeration apparatus 25. Therefore, in this prior art, the shroud 4 formed integrally with the shelf board 3 divides the space communicating with the exhaust space R1 side from the space communicating with the upper side of the cooling water tank 20 into the rear of the cooling water tank 20. The electrical equipment box 29 is provided on the support plate portion 4b of the shroud 4 that is formed on the side of the shroud 4, and condensation occurs in the electrical equipment box 29 due to the exhaust gas whose temperature has risen by cooling the high-temperature condenser 27. It is preventing.

  In the prior art as described above, since the cooling fan 28 is exposed when the ceiling plate 15 is removed for maintenance and inspection, the fan guard 5 is necessary to prevent the rotating fan from touching the hand.

  In the above-described prior art, the exhaust gas whose temperature has been increased by cooling the condenser 27 is exhausted upward from the cooling fan 28 into the exhaust space R1, and this exhaust gas is exhausted into the side panels 12b and the rear panel 14 as indicated by an arrow L4. And flow in substantially orthogonal directions and are discharged to the outside through the exhaust ports 17 and 17a. When there is a sufficient space around the beverage dispenser 1, the exhaust discharged to the outside from the exhaust ports 17 and 17a continues to flow straight, so that a sufficient amount of cooling air can be obtained and the condenser 27 is sufficiently To be cooled. However, as shown in FIGS. 6 and 7, when there is not enough clearance between the panels 12b and 14 as the peripheral wall of the housing 11 and the inner wall W of the building or the outer wall K of the peripheral equipment, Since the exhaust discharged to the outside from the ports 17 and 17a immediately hits the inner wall W and the outer wall K, the discharge resistance is increased, and the amount of cooling air passing through the condenser 27 is decreased, and the refrigerant may not be sufficiently cooled. . Further, the exhaust discharged from the lower half of the exhaust ports 17, 17 a passes between the inner wall W of the building and the outer wall K of the peripheral equipment, and goes down to be sucked again from the lower intake port in the housing 11. As a result, a short cycle of exhaust occurs, and the intake air becomes hot and the refrigerant in the condenser 27 cannot be sufficiently cooled. As a result, there arises a problem that the cooling water tank 20 of the beverage dispenser 1 cannot be sufficiently cooled. Further, the temperature of the exhaust gas discharged into the exhaust space R1 rises due to a decrease in the amount of cooling air passing through the condenser 27, and the internal temperature of the electrical box 29 provided in the space communicating with the exhaust space R1 also rises. An air hole for cooling is required in the box 29, and a new problem that dust enters the electrical equipment box 29 also arises. The object of the present invention is to solve each of these problems.

For this purpose, the beverage dispenser according to the first aspect of the present invention includes a cooling water tank that cools a beverage and a refrigeration device that cools the cooling water tank in a housing, and a cooling fan for a condenser that constitutes the refrigeration apparatus. A beverage dispenser in which air introduced from the lower intake port in the housing is driven to cool through the condenser, and the air that has passed through the condenser is discharged from the upper exhaust port on the peripheral wall of the housing. In the housing, the exhaust made of air that has passed through the condenser is slanted from the exhaust port by a duct cover provided with a guide plate that is inclined so as to become higher on the upper side of the exhaust port on the upper side of the exhaust port. A path that flows upward is formed.

  In the beverage dispenser described in claim 1, as described in claim 2, it is preferable that the control device for controlling the operation of the refrigeration apparatus is disposed apart from the path through which the exhaust gas flows in the housing.

  Moreover, the drink dispenser of Claim 2 forms the small space partitioned from the channel | path through which exhaust_gas | exhaustion flows in the position which becomes the upper side of the cooling water tank in a housing like Claim 3, and in a small space It is preferable to arrange a stirring motor and a control device of a stirring device for stirring the cooling water in the cooling water tank.

According to the first aspect of the present invention, the air that has passed through the condenser by the duct cover provided with the guide plate that is inclined so as to become higher in the housing at the upper side of the exhaust port on the upper side of the exhaust port. since become more exhaust to form a path that flows diagonally upward from the exhaust port, the exhaust gas is upwardly discharged to the condenser exhaust space through the, along a guide plate of the duct cover without upward momentum Sogareru The flow that flows obliquely upward and is discharged from the exhaust port also has an upward component. If there is not enough clearance between each panel that forms the peripheral wall of the housing and the inner wall of the building or the outer wall of peripheral equipment, the discharge resistance will increase, so the amount of cooling air flowing through the condenser will be reduced to some extent, and the beverage dispenser It is inevitable that the beverage cooling performance is reduced. However, most of the exhaust discharged from the exhaust port flows upward through the gap between the inner wall W of the building and the outer wall K of the peripheral equipment due to the upward component of the flow, and immediately above the housing. Released to a large space. As a result, the exhaust resistance is reduced, and the exhaust that goes down along the inner wall of the building and the outer wall of the peripheral equipment is also reduced, so that such exhaust is again sucked from the lower intake port in the housing. The short cycle of exhaust is also reduced, and the deterioration of the beverage cooling performance of the beverage dispenser due to the short cycle of exhaust is greatly improved.

  According to the second aspect of the present invention, since the control device for controlling the operation of the refrigeration apparatus is arranged away from the path through which the exhaust flows in the housing, the control device is heated by the exhaust whose temperature has increased. Things will disappear. If there is not enough clearance between each panel that forms the peripheral wall of the housing and the inner wall of the building or the outer wall of peripheral equipment, the exhaust resistance increases and the amount of cooling air passing through the condenser decreases, increasing the exhaust temperature. However, even in such a case, the control device is not heated by the exhaust gas whose temperature has risen, so that trouble due to the temperature rise of the control device does not occur. As a result, there is no need to provide a cooling through-hole in the box housing the control device, and the problem of such dust intrusion into the box is also solved.

  According to the third aspect of the present invention, the small space partitioned from the passage through which the exhaust flows is formed at a position above the cooling water tank in the housing, and the cooling water in the cooling water tank is stirred in this small space. The agitation motor and the control device of the agitation device are arranged, and the control device is gently heated by the heat generated by the operation of the agitation motor, so that no condensation occurs in the control device due to the cold air from the cooling water tank. Heating by this stirring motor is stable, and the temperature of the control device is not influenced by the influence of the installation environment such as the gap between each panel around the housing and the inner wall of the building or the outer wall of the peripheral equipment. Therefore, condensation of the control device is completely prevented and the control device is not heated and the temperature does not rise excessively.

The substantially same parts are denoted by the same reference numerals as those in FIGS. Detailed description will be omitted.

  As shown in FIGS. 1 to 4, the shelf board 16 is obtained by removing the shroud 4 from the prior art shelf board 3 shown in FIGS. 6 and 7, and the left and right side panels 12 b of the housing body 12 of the housing 11. It is fixed with screws. A condenser 27 and a cooling fan 28 are attached to the lower surface and the upper surface of the shelf plate 16 in the same manner as the above-described conventional technology. The positions of the condenser 27 and the cooling fan 28 may be interchanged. The guide support plate 30 is substantially the same height as the connecting portion 4a of the shroud 4 of the prior art described above, and bent portions 30a and 30b for attachment are formed along the upper and lower edges. By screwing the lower bent portion 30a, the guide support plate 30 is erected and fixed to the rear edge portion of the shelf board 16 with a slight gap between the guide support plate 30 and the rear surface of the heat insulating material 20a.

  A support plate 23 that covers the same top surface of the cooling water tank 20 and the heat insulating material 20a as in the prior art except for a part of the front part is supported by the upper part of the cooling water tank 20. A stirring motor 24a of the stirring device 24 is fixed to the center of the cooling water tank 20 on the upper surface of the support plate 23, and a stirring blade 24c for stirring the cooling water is fixed to the tip of the shaft 24b extending downward therefrom. ing. In addition, an electrical box (box body for housing the control device) 29 for controlling the operation of the refrigeration apparatus 25 is provided on the upper surface of the support plate 23 on the rear side of the stirring motor 24a.

  As shown in FIGS. 2 to 4, between the shelf board 16 and the ceiling board 15 in the housing 11, the exhaust gas whose temperature has risen through the condenser 27 and the cooling fan 28 is passed as in the prior art. An exhaust space R1 to be discharged is formed, and a duct cover 32 is provided in the upper half of the exhaust space R1. Further, a water tank side cover 35 is provided at a position between the support plate 23 and the ceiling plate 15 in the housing 11. The duct cover 32 and the water tank side cover 35 are integrally formed in this embodiment, but may be formed separately as in a modified example described later shown in FIG.

  The duct cover 32 includes a guide plate 33 that is inclined so as to become higher toward the back panel 14 side where the exhaust port 17a is formed in the upper portion, and a substantially right triangular side plate that is bent so as to extend upward from both sides thereof. 34, and the width of the guide plate 33 is slightly narrower than the internal dimension between the flange portions 12c, 12c on the upper edges of the side panels 12b, 12b of the housing 11. The guide plate 33 has a narrow horizontal portion 33a formed on the front end side thereof screwed and fixed onto the bent portion 30b on the upper side of the guide support plate 30 that is erected and fixed to the shelf plate 16 as described above. , Is inclined as described above and extends close to the back panel 14. In this attached state, the outward bent portions 34 a and 34 a formed at the upper edge portions of the side plates 34 and 34 are hooked and supported on the flange portions 12 c on both sides of the housing body 12. In this embodiment, as shown in FIGS. 2 and 3, the side plates 34 and 34 and the bent portions 34 a and 34 a are not formed in a narrow range corresponding to the horizontal portion 33 a of the guide plate 33. A portion of the exhaust space R1 located between the shelf board 16 and the duct cover 32 forms a path through which the exhaust of the present invention flows.

  The water tank side cover 35 is integrally connected to the front end edge of the horizontal portion 33 a of the guide plate 33 of the duct cover 32 and is bent upward, and the rising plate portion 36 is connected to the side plate of the duct cover 32. The horizontal plate portion 37 bent in the forward horizontal direction at the same height position as the bent portion 34a of 34, and the horizontal plate portion 37 at a position slightly before the front edge of the support plate 23 that supports the stirring motor 24a. It is comprised by the support leg part 38 bent downward. The lateral width of the rising plate portion 36 and the support leg portion 38 is approximately the same as the lateral width of the guide plate 33 of the duct cover 32, and the horizontal width of the horizontal plate portion 37 is wider than that and the bent portions 34 a, 34 a of the side plates 34, 34. The width is the same as the width between the tips. The support leg 38 is formed with a rectangular cutout 38a for avoiding interference with the stirring motor 24a, and a bent part 38b for screwing and fixing to the support plate 23 at the lower edge of the support leg 38. Is formed. A small space R2 that is substantially partitioned from the above-described path through which the exhaust flows is formed by the water tank side cover 35 at a position on the upper side of the cooling water tank 20 in the housing 11, although there are some gaps in various places. The stirring device 24 and the electrical box 29 are disposed in the small space R2.

  The horizontal portion 33 a connected to the lower edge of the rising plate portion 36 is screwed to the upper bent portion 30 b of the guide support plate 30, and the lower bent portion 38 b of the support leg portion 38 is screwed to the support plate 23. In this state, both side portions of the horizontal plate portion 37 of the water tank side cover 35 are supported on the flange portions 12 c and 12 c of the side surface panels 12 b and 12 b of the housing body 12.

  As in the case of the prior art described above, also in this embodiment, the refrigerant compressed by the compressor 26 of the refrigeration apparatus 25 is cooled and liquefied by the air sucked by the cooling fan 28 when passing through the condenser 27, It is sent to the evaporation pipe 22 in the cooling water tank 20, where it is vaporized to cool the cooling water and then returned to the compressor 26. Thereby, the cooling water in the cooling water tank 20 is cooled, and a frozen ice layer is formed around the evaporation pipe 22. Beverages such as beer supplied from a beverage supply source are cooled by the cooling water in the cooling water tank 20 when passing through the beverage cooling pipe 21, and are poured out from the dispensing cock 21a into a container such as a glass.

  According to this embodiment, most of the exhaust gas that has cooled the condenser 27 and is discharged upward from the cooling fan 28 into the exhaust space R1 is upwardly directed as indicated by an arrow L1 in FIGS. There is no momentum, it flows obliquely upward along the guide plate 33 of the duct cover 32, and the flow after being discharged from the exhaust port 17a of the back panel 14 also has an upward component. As shown in FIGS. 2 and 3, when there is not enough clearance between the rear panel 14 serving as the peripheral wall of the housing 11 and the inner wall W of the building, the exhaust resistance of the exhaust discharged from the exhaust port 17a is Since it becomes high, it is inevitable that the amount of cooling air passing through the condenser 27 decreases to some extent and the beverage cooling performance of the beverage dispenser 10 decreases. However, most of the exhaust discharged from the exhaust port 17a flows upward through the gap between the building and the inner wall W due to the upward component of the flow, and is immediately released into a wide space above the housing 11. As a result, the increase in the discharge resistance of the exhaust gas is reduced, so that the deterioration of the beverage cooling performance of the beverage dispenser 10 is reduced. At the same time, the amount of exhaust gas that flows downward along the inner wall W of the building is reduced, and the short cycle of the exhaust gas that is re-inhaled from the lower intake port in the housing 11 is also reduced. Will be reduced.

  In this embodiment, a small space R2 partitioned from a passage through which exhaust air between the shelf board 16 and the duct cover 32 flows is formed at a position above the cooling water tank 20 in the housing 11, and the small space R2 is formed in the small space R2. An electrical box 29 for controlling the operation of the refrigeration apparatus 25 is disposed. Thus, since the electrical equipment box 29 is disposed in the small space R2 separated from the above-mentioned path through which the exhaust gas whose temperature has increased through the condenser 27 and the cooling fan 28 flows, the electrical equipment box is caused by the exhaust gas whose temperature has increased. There is no risk of 29 being heated. When there is not enough clearance between each panel 12b, 14 which becomes the peripheral wall of the housing 11 and the inner wall W of the building or the outer wall K of the peripheral device, the discharge resistance is increased and the amount of cooling air flowing through the condenser 27 is increased. However, even if the exhaust temperature rises as described above, the electrical equipment box 29 is not heated by the exhaust gas, so there is a problem due to the temperature rise of the electrical equipment box 29. It will never happen. Therefore, it is not necessary to provide a cooling through hole in the electrical box 29, and the problem of dust intrusion into the electrical box 29 is solved.

  In this embodiment, the agitating motor 24a of the agitating device 24 for agitating the cooling water in the cooling water tank 20 and the electrical box 29 are arranged in the small space R2. In this way, the electrical box 29 is provided with the agitating motor. Since it is heated gently by the heat generated by the operation of 24a, dew condensation does not occur in the electrical box 29 due to the cool air from the cooling water tank 20.

  Further, according to this embodiment, even if the ceiling plate 15 is removed for maintenance and inspection, the cooling fan 28 is covered with the duct cover 32, so that the fan guard 5 required in the above-described prior art is not necessary. .

  Next, a modification of the duct cover shown in FIG. 5 will be described. The duct cover 32 of the embodiment described above with reference to FIGS. 1 to 4 is integrally formed with the water tank side cover 35, and the left and right side plates 34, 34 are flat plates, but the duct of the modified example shown in FIG. The cover 32A is formed separately from the water tank side cover 35, and the left and right side plates 34A, 34A have upper flat portions 34A1, 34A1 that are parallel to each other as in the previous embodiment. The lower portion is different from the duct cover 32 of the previous embodiment in that it is a planar inclined side guide plate 34A2 bent inward so as to approach each other.

  That is, in the duct cover 32A of this modification, in addition to the guide plate 33A that is inclined so as to increase toward the back panel 14 side where the exhaust port 17a is formed in the upper part, the left and right sides in which the exhaust port 17 is formed in the upper part. The side guide plates 34A2 that are inclined so as to increase toward the side panels 12b and 12b are provided. The narrow horizontal portion 33A1 formed at the front end portion of the guide plate 33A is shorter than the length of the horizontal portion 33a of the previous embodiment, and inside and below the left and right side guide plates 34A2 and 34A2 at both ends of the horizontal portion 33A1. The tip part which becomes is connected. Accordingly, the guide plate 33A has a shape in which the lateral width gradually increases from the front end connected to the horizontal portion 33A1 to the rear upper side, and the side guide plates 34A2 and 34A2 extend from the inner end connected to the horizontal portion 33A1. It is a shape in which the lateral width gradually increases as it goes upward on both outer sides. On the upper edge portions of the constant width portions 34A1 and 34A1 at the upper portions of the left and right side plates 34A, outward bent portions 34a and 34a similar to those of the above-described embodiment are formed. In the illustrated modification, the left and right side guide plates 34A2 and 34A2 have different inclination angles, but may have the same angle.

  In this modification, a bent portion 36a formed on the lower edge of the rising plate portion 36 of the water tank side cover 35 is overlapped on the bent portion 30b on the upper edge of the guide support plate 30 and screwed, and the duct cover 32A The horizontal portion 33A1 at the front edge is superimposed on the bent portion 36a at the rear lower edge of the water tank side cover 35, and is screwed to the guide support plate 30 and the water tank side cover 35. In this attached state, the side plates 34A and 34A of the duct cover 32A have their respective bent portions 34a and 34a on the upper edge and both sides of the horizontal plate portion 37 of the water tank side cover 35 abutted on the left and right side panels 12b and 12b. Supported.

  In the above-described embodiment, most of the exhaust discharged from the exhaust port 17a of the rear panel 14 flows immediately upward through the gap between the inner wall W of the building due to the upward component of the flow and the housing. Since it is discharged into a wide space above 11, the increase in the exhaust resistance of the exhaust gas is reduced, and the exhaust gas that circulates downward along the inner wall W of the building is reduced and the short cycle of the exhaust gas is also reduced. Performance degradation is greatly reduced. However, in the embodiment described above, the flow of exhaust discharged from the exhaust ports 17 of the left and right side panels 12b, 12b has no upward component force as shown by the arrow L2 in FIG. Can not. However, according to this modification, as shown by an arrow L3 in FIG. 5, the exhaust discharged from the exhaust ports 17 of the left and right side panels 12b and 12b is also obliquely upward along the left and right side guide plates 34A2 and 34A2. And has an upward component even after being discharged from the exhaust ports 17 and 17 of the left and right side panels 12b and 12b. As a result, the exhaust exhausted from the exhaust ports 17 and 17 of the left and right side panels 12b and 12b is similar to the exhaust exhausted from the exhaust port 17a of the rear panel 14 due to the upward component of the flow and the outer wall K of the peripheral device. Immediately after passing through the gap between the two, and immediately released into a wide space above the housing 11, the increase in the exhaust resistance is reduced, and the exhaust that goes downward along the inner wall W of the building is also reduced. Shortening the exhaust cycle will also decrease. Therefore, the deterioration of the beverage cooling performance of the beverage dispenser 10 can be further reduced as compared with the case of the above-described embodiment.
