Description

  The present invention relates to a refrigerator built-in showcase having a gantry that houses at least a condenser and a blower that are part of a refrigerator unit.

  Conventionally, as a refrigerated / frozen showcase installed in a store such as a supermarket or a convenience store, it has a showcase body having a product display room and a gantry arranged at the lower part thereof, and a refrigerator unit in the gantry. There is known a refrigerator-incorporated showcase that houses at least a condenser and a blower that are part of the refrigerator. In the refrigerator built-in showcase, the fan is driven to suck the air in the store into the gantry, and the sucked air is applied to the condenser to promote the condensation of the refrigerant in the condenser.

  As an example of such a refrigerator built-in showcase, one described in Patent Document 1 below is known.

  In the refrigerator built-in showcase described in Patent Document 1, a vent cover with a plurality of vent holes formed on the front surface of the gantry is rotatably provided, and a condenser filter is detachable inside the vent cover. Installed on. The vent cover is provided with a horizontally-oriented support shaft on the lower end side, and with this support shaft as the center, the upper end side stands up and closes the front side of the gantry, and the upper end side tilts toward the front side of the gantry To the open position that opens the front side of the gantry. When the air vent cover with the condenser cover inside is rotated to the closed position, the air in the store passes through the air vent and the condenser filter and is sucked into the gantry by driving the blower. As a result, the dust contained in the air adheres to the condenser filter and is removed, and the air from which the dust has been removed comes into contact with the condenser and the blower, thereby preventing the dust from adhering to the condenser and the blower.

  When dust adheres to the condenser filter, the amount of air sucked into the gantry decreases as the amount of dust attached increases, and the amount of air striking the condenser also decreases, so the refrigeration performance of the refrigerator unit decreases. Therefore, when a certain amount of dust adheres to the condenser filter, it is necessary to clean the condenser filter and restore the refrigeration performance of the refrigerator unit. To clean the condenser filter, rotate the vent cover to the open position, remove the condenser filter from the vent cover rotated to the open position, and wash the removed condenser filter or suck it with a vacuum cleaner. Is going.

  However, in the refrigerator-incorporated showcase described in Patent Document 1, in order to remove the condenser filter from the vent cover when the condenser filter is cleaned, a screw or a hook that fixes the vent hole cover, etc. It is necessary to remove the condenser cover, rotate the vent cover to the open position, and then remove the condenser filter from the vent cover, and it takes time to clean the condenser filter. For this reason, the cleaning of the condenser filter may be postponed, especially when the store staff is in business for 24 hours and is not familiar with the cleaning of the condenser filter. As a result, there is a situation in which the power is consumed for a long time, and the refrigeration performance of the refrigerator unit is reduced to increase the power consumption.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a refrigerator-incorporated showcase capable of easily and quickly cleaning a condenser filter without trouble. That is.

  The refrigerator built-in type showcase according to the present invention includes a showcase body having a product display chamber therein, and at least a condenser and a blower which are disposed at a lower portion of the showcase body and are part of the refrigerator unit inside. And a condenser filter that is provided in front of the gantry and has a plurality of ventilation holes formed therein, and a condenser filter that is detachably attached to the inside of the ventilation hole cover. The filter is slidable in the vertical direction and is mounted in a forward-tilt posture in which the upper end portion is inclined toward the front side of the gantry. A gripping part is provided.

  Further, in the above-described refrigerator built-in type showcase, a cutout portion into which the condenser filter is inserted is formed at an upper portion of the vent hole cover, and the condenser filter that is slid inside the vent hole cover is disposed in front. It is desirable that a guide portion that guides downward in an inclined posture is formed.

  Further, in the above-described refrigerator-incorporated showcase, it is preferable that the vent hole of the vent cover is formed by punching.

  In the refrigerator built-in showcase according to the present invention, the condenser filter attached to the vent hole cover is attached in a forward inclined posture in which the upper end portion is inclined toward the near side of the gantry and is slidable in the vertical direction. Installed. For this reason, when removing the condenser filter from the vent hole cover for cleaning, it is only necessary to hold the gripping part and pull the condenser filter upward, and it is possible to remove the condenser filter easily and quickly without trouble. In addition, the condenser filter attached to the air vent cover is installed in a forward tilted posture with the upper end inclined toward the front of the gantry.

It is a cross-sectional side view which shows the mount frame in the state where the filter for condensers is attached to the vent hole cover. It is a cross-sectional side view which shows the mount frame in the state where the filter for condensers is removed from the vent hole cover.

  A refrigerator built-in showcase according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing, in section, a part of a refrigerator-incorporated showcase 1 installed in a store such as a supermarket or a convenience store. This refrigerator built-in type showcase 1 includes a showcase main body 2 and a gantry 3 disposed at a lower portion of the showcase main body 2.

  Inside the showcase body 2 is formed a product display chamber 4 in which the top is opened to display products.

  A refrigerator unit 5 is accommodated in the gantry 3. The refrigerator unit 5 includes a compressor that compresses a refrigerant, a condenser that condenses the compressed refrigerant, an expander that adiabatically expands the condensed refrigerant, a cooler that evaporates the adiabatic expanded refrigerant, a condenser and a cooling unit It is comprised by the air blower etc. which blow it toward a container. The compressor, the condenser, the expander, and the cooler are connected by a pipe through which the refrigerant flows. When the blower is driven and blown toward the cooler, the air hitting the cooler is cooled, and the cooled air is supplied into the commodity display chamber 4.

  A vent hole cover 6 is attached to the front surface of the gantry 3, and the vent hole cover 6 is fixed to the gantry 3 using screws and bolts. A plurality of air holes 7 are formed in the air hole cover 6 by punching. The vent hole cover 6 is disposed at a position facing at least the condenser in the refrigerator unit 5. A condenser filter 8 is detachably attached to the inside of the vent hole cover 6.

  FIG. 2 is a cross-sectional side view showing the gantry 3 with the condenser filter 8 attached to the vent hole cover 6. The condenser filter 8 attached to the inside of the vent hole cover 6 is slidable in the vertical direction, and has a forward inclined posture in which the upper end portion is inclined toward the near side of the mount 3. The upper end of the condenser filter 8 is provided with a grip portion 9 that is held when the condenser filter 8 is slid up and down to be attached and detached. The grip portion 9 is formed by being bent in an L shape, and the direction of the bending is such that it is the front side of the gantry 3 when the condenser filter 8 is attached to the vent hole cover 6.

  FIG. 3 is a sectional side view showing the gantry 3 in a state where the condenser filter 8 is removed from the vent hole cover 6. A cutout portion 10 into which the condenser filter 8 is inserted is formed in the upper portion of the vent hole cover 6. Further, guide portions 11 are formed on both sides of the vent hole cover 6 to guide both sides of the condenser filter 8 when the condenser filter 8 inserted from the notch portion 10 is slid downward.

  In such a configuration, the refrigerator built-in showcase 1 is used with the condenser filter 8 attached to the inside of the vent hole cover 6 as shown in FIGS. By driving the blower, the air in the store passes through the vent hole 7 of the vent cover 6 and the condenser filter 8 and is sucked into the gantry 3. The air sucked into the gantry 3 hits the condenser, and the condensation of the refrigerant in the condenser is promoted.

  When air in the store is sucked into the gantry 3, dust contained in the air adheres to the condenser filter 8 and is removed. And the clean air from which the dust was removed hits the condenser and the blower, and the adhesion of the dust to the condenser and the blower is prevented.

  When dust adheres to the filter 8 for the condenser, the amount of air sucked into the gantry 3 decreases as the amount of dust attached increases, and the amount of air striking the condenser also decreases, so the refrigeration performance of the refrigerator unit 5 decreases. Therefore, when a certain amount of dust adheres to the condenser filter 8, it is necessary to clean the condenser filter 8 in order to restore the refrigeration performance of the refrigerator unit 5.

  When the condenser filter 8 is to be cleaned, the condenser part 8 of the condenser filter 8 is grasped, the condenser filter 8 is pulled upward, and the condenser filter 8 is removed from the vent hole cover 6 as shown in FIG. Therefore, the operation of removing the condenser filter from the vent hole cover 6 and the operation of cleaning the removed condenser filter 8 can be performed easily and quickly without taking time.

  When the condenser filter 8 that has been cleaned is attached to the inside of the vent cover 6, the lower end portion of the condenser filter 8 is inserted through the notch portion 10, and the inserted condenser filter 8 is moved along the guide portion 11. Just slide it down. Accordingly, the condenser filter 8 can be easily and quickly attached to the inside of the vent hole cover 6 without taking time and effort.

  Here, the condenser filter 8 attached to the vent hole cover 6 is attached in a forward inclined posture in which the upper end portion is inclined toward the near side of the gantry 3. For this reason, when a customer in front of the refrigerator-incorporated showcase 1 looks down on the gantry 3 side, the surface of the condenser filter 8 becomes difficult to see from the vent hole 7 of the vent hole cover 6, and the surface of the condenser filter 8. Dust adhering to the customer becomes difficult to see. Therefore, it is possible to prevent the appearance in the store from being damaged because the dust adhering to the surface of the condenser filter 8 is visible to the customer.

  Further, the grip portion 9 is formed by being bent in an L shape, and the direction of the bending is such that it is the front side of the gantry 3 when the condenser filter 8 is attached to the vent hole cover 6. For this reason, when the customer looks down on the gantry 3 side, the dust adhering to the surface of the condenser filter 8 becomes more difficult to see from the customer. Therefore, it is possible to further prevent the aesthetic appearance in the store from being damaged because the dust adhering to the surface of the condenser filter 8 is visible to the customer.

  In addition, since the air holes 7 of the air hole cover 6 are formed by punching, the work of forming the air holes 7 can be performed at low cost without labor. Moreover, even if the vent hole 7 is punched so that the inside of the gantry 3 can be easily seen, the condenser filter 8 attached to the vent hole cover 6 has its upper end inclined to the near side of the gantry 3. Since it is attached in a forward tilted posture, the dust adhering to the surface of the condenser filter 8 is difficult to see from the vent hole 7 when the customer looks down on the gantry 3 side. Further, since the air holes 7 are formed by punching, when dust adheres to the air holes 7, the dust can be easily cleaned, and since the dust adheres to the air holes 7, It is possible to prevent the beauty of the inside from being spoiled.

  In the present embodiment, the refrigerator-incorporated showcase 1 including the open-type showcase body 2 having the product display chamber 4 opened at the top is described as an example. The present invention can also be applied to a refrigerator-incorporated showcase having a reach-in type showcase body having a flexible glass door.
