Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem on the failure caused by corrosion of a condenser by cleaning water in a conventional condenser where the volume of cleaning liquid stored is small in cleaning the condenser and a lower face of the condenser is kept into contact with a cleaning water receiving pan in a wide range over the lower face of the condenser. <P>SOLUTION: In this condenser 6 and the mounting table/water receiving pan 8, the condenser 6, the mounting table/water receiving pan 8 for the condenser 6 and a holding part 7 for holding the condenser 6 are mounted, and the mounting table/water receiving pan 8 is normally used as a mounting table of the condenser 6, and reversed in cleaning to be used as a water receiving pan, thus a large amount of cleaning water can be stored even under a mounting state where a drainage hose can not be connected, and further the failure caused by corrosion can be reduced as the cleaning water and the condenser 6 are not kept into contact with each other after cleaning. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a cooling unit, and more particularly to a condenser of a refrigeration cycle.

  In the cooling storage, cooling is generally performed using a refrigeration cycle including a compressor, a condenser, and a cooler.

  In a condenser, in order to promote more heat exchange with ambient air, more ambient air is sent to the condenser using an electric blower. If the cooling storage is used in this state for a long time, dust and dust adhere to the condenser and it becomes clogged, reducing the efficiency of heat exchange in the condenser and reducing the cooling capacity. Cleaning is necessary.

  Conventionally, in order to clean this type of condenser, a receiving tray for cleaning water is attached directly under the condenser (for example, see Patent Document 1).

  FIG. 6 shows the cleaning specification of the conventional condenser described in Patent Document 1. As shown in FIG. 6, it includes a condenser 1, a unit base 2, a cooling storage 3, and a water tray 4.

  Hereinafter, a conventional technique for dealing with cleaning of the conventional condenser will be described.

The unit base 2 is installed in a machine room, a water tray 4 is installed over the inside and front of the unit base 2, and the condenser 1 is installed inside the water tray 4. The cleaning liquid generated at the time of cleaning 1 flows down into the space using the head between the unit base 2 and the main body top wall, and is discharged through the drain pipe 5 from there.
JP-A-3-148572

  However, in the above conventional configuration, although the condenser can be cleaned, the cleaning water is stored in the space between the unit base height and the unit base and the cooling storage, and the capacity of the cleaning liquid is small. Since the bottom surface of the plate and the dish for receiving the cleaning water are in contact with the entire bottom surface of the condenser over a wide area, the condenser is corroded by the cleaning water and may cause a failure.

  The present invention solves the conventional problem, and can collect a large amount of cleaning water even in an installation situation where a drainage hose cannot be connected, and the cleaning water and the condenser do not come into contact with each other after cleaning. An object is to provide a condenser that reduces failure.

  In order to solve the above-mentioned problems, the condenser according to the present invention is mainly characterized in that an installation stand and a water tray that serve as a cleaning water tray are added during cleaning.

  The condenser installation table and water receiving tray is a box with an opening on one side of the condenser, and has a length longer than the depth and width of the condenser. Sometimes the opening surface is on the bottom, and the contact surface with the condenser is placed so that there is no gap space.When cleaning the condenser, the box is turned upside down and the opening surface is placed on the condenser side. It is characterized in that it receives the cleaning liquid at the time of cleaning in the vessel installation table and water tray.

  This increases the permissible amount of the dish that receives the cleaning water at the time of cleaning, and the condenser is not always immersed in the cleaning water after cleaning, so that failure due to corrosion is reduced. Furthermore, since the amount of air passing through the condenser is not reduced during normal operation, there is no loss in heat exchange in the condenser.

  The condenser and installation stand / water tray of the present invention can clean the condenser without impairing the heat exchange efficiency in the condenser and suppressing corrosion caused by cleaning water.

  1st invention cleans by arrange | positioning the installation stand and water receiving tray used as an installation stand and a water receiving tray at the time of cleaning to the condenser in the cooling unit attached to the side surface or upper and lower surfaces of the heat insulation box which comprises a cooling storage. Sometimes it is possible to clean while accumulating enough cleaning water, and during normal operation, it does not impair the heat exchange efficiency in the condenser and condenses while maintaining a long life by suppressing corrosion caused by cleaning water The vessel can be cleaned.

  According to the second aspect of the present invention, the portion of the condenser holding portion that is not in contact with the condenser is positioned higher than the condenser, so that the cleaning water transmitted from the holding portion can be obtained by obtaining a draining effect when cleaning the condenser. This prevents the water from flowing out of the water tray, and more reliably collects cleaning water in the water tray and reduces the accumulation of moisture between the condenser and the holding part. Failure due to corrosion can be reduced.

  The third aspect of the invention divides the holding of the condenser into two or more parts, thereby eliminating the contact between the condenser and the holding part on the lower surface of the condenser, thereby preventing the corrosion of the cleaning water from moisture. It can be further reduced.

  4th invention can be cleaned, without worrying about the quantity of the cleaning water which accumulates in a water receiving tray by providing the drain outlet for cleaning water drainage in the installation stand and water receiving tray at the time of cleaning.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
