Abstract

(57) [Summary] [Objective] To obtain a refrigerating device that can be easily serviced from the service side without removing the refrigerating device from the commercial refrigerator when servicing the blower or the like of the refrigerating device. A fan cover 13 which is integrated with the plate fin type condenser 4 and has a part of a fan guide hole,
A detachable service cover 17 is provided on the fan cover 13 to form a divided structure.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of serviceability of a blower or the like of a refrigeration system.

[0002]

[Prior Art]

 2 and 3 are respectively a perspective view and a plan view of a conventional refrigerating apparatus, and FIG. 4 is a perspective view showing an installed state of the conventional refrigerating apparatus. In the figure, 1 is a unit base, 2 is a compressor, 3 is an electrical component, 4 is a plate fin type compressor, 5 is a blower for passing heat exchanged air to the condenser 4, and 6 is a blower 5. A rotating motor, 7 is a blower mounting plate for mounting the motor 6, and is fixed on the unit base 1 by screws 8 or the like. Further, 9 is a refrigerant pipe. 10 is a refrigerating apparatus, and 11 is a commercial refrigerator. Next, the service of the blower 5 and the motor 6 will be described. The refrigerating apparatus 10 may be installed on the upper part of the commercial refrigerator 11, etc. The commercial refrigerator 11 must have a structure that is compact and has many stored items. Therefore, it is necessary to reduce the width dimension a of the commercial refrigerator 11 and the vertical dimension b thereof, and to reduce the vertical dimension c of the portion accommodating the refrigerating apparatus 10. Therefore, there is no space on the side surface or the upper part of the refrigerating apparatus 10, and only the service surface 12 has a service space.

However, in the service of the blower 5 and the like, the screw 8 that fixes the blower mounting plate 7 to the unit base 1 cannot be removed from the upper part, so the refrigerating device 10 is replaced with the commercial refrigerator. Take out from 11, remove the screw 8 and remove the blower 5 and the like together with the blower mounting plate 7 to perform service.

[0004]

[Problems to be solved by the device]

 Since the conventional blower mounting structure of the refrigeration system is configured as described above, the refrigeration system must be taken out when servicing the blower, etc., and there is also a refrigerant pipe around the blower. There were some problems such as getting in the way when removing it.

The present invention has been made to solve the above-mentioned problems, and when servicing a blower or the like, it is possible to service the blower or the like from the service side without removing the refrigeration system. The purpose is to obtain a freezer.

[0006]

[Means for Solving the Problems]

 A refrigerating apparatus according to the present invention comprises a unit base including a compressor, a plate fin type condenser, a blower and a motor for passing heat exchanged air to the condenser, and a blower mounting plate for fixing the blower and the motor. In the refrigeration system, a fan cover that is integrated with a plate fin type compressor and has a part of a fan guide, and a service cover that can be freely attached and detached to the fan cover are provided.

[0007]

[Action]

 The refrigeration system according to the present invention, when servicing a blower or the like, removes the service cover that can be freely attached and detached from the service side to service the blower and the like.

[0008]

【Example】

 Example 1. An embodiment of the present invention will be described below with reference to the drawings. In the figure, the same symbols as in the conventional device indicate the same parts. In FIG. 1, 13 is a fan cover attached to the condenser 4 for forming an air passage, 14 is an upper plate portion of this fan cover, 15 is a side plate portion, and 16 is a front portion having a part of the fan guide hole 20. It is a plate part. Reference numeral 17 denotes a service cover that can be freely attached to and detached from the fan cover 13, and is attached to the fan cover with screws 8. 18 is a screw hole for fixing the service cover 17 provided on the side surface of the condenser 4. Reference numeral 19 denotes a part of the upper plate portion 14 of the fan cover, which is a fan cover receiving plate portion provided with a screw hole for fixing the service cover 17.

With the above configuration, when servicing the blower 5 and the motor 6, the service cover 17 is first removed from the fan cover 13 and pulled out toward the service surface 12. After this work, the blower 5 is removed from the motor 6 and pulled out toward the service surface 12. Further, the motor 6 is removed from the blower mounting plate 7 and pulled out toward the service surface 12. When the removal work is completed and the service is finished, perform the installation work from the direction of the service surface 12 to the refrigerator 10 main body in the reverse order of the removal work.

[0010]

[Effect of the device]

 As described above, according to the present invention, since the fan cover has a partly divided structure, the service of the blower and the motor can be done from the service side, so the refrigerator can be removed from the commercial refrigerator etc. There is no need to do this, and it has a great effect on improving serviceability.
