Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention aims to make the entire device more compact, and also to drain oil leaked from the heating unit outside the machine without affecting the wiring. The present invention relates to a petroleum refrigerant heating/cooling device that discharges oil refrigerant.

(Prior art) The outdoor unit of a conventional petroleum refrigerant heating/cooling system includes a heating unit such as a combustor, a heater, and a combustion fan, a compressor,
The refrigeration cycle section, such as a condenser and a cooling fan, is a separate unit, and the heating unit section is arranged on the side of the refrigeration cycle section.

(Problems to be Solved by the Invention) In the petroleum refrigerant heating/cooling device of the above type, the refrigeration cycle section and the heating unit section are arranged in the same plane.
There is a limit to reducing the installation area, which is a bottleneck in making the entire device more compact.

The present invention has been made in view of the above-mentioned points, and is an oil refrigerant heating system that aims to make the entire device more compact and also discharges oil leaking from the heating unit to the outside of the machine without affecting the wiring. The purpose is to provide heating and cooling equipment.

[Structure of the invention]

(Means for Solving the Problems) The petroleum refrigerant heating/cooling device of the present invention divides the inside of the outdoor unit main body into two upper and lower chambers by a horizontal partition plate, and the upper chamber has a heating unit such as a combustor, a heater, and a combustion fan. At the same time, a refrigeration cycle section such as a compressor, a condenser, and a cooling fan is arranged in the lower chamber, and a U-shaped protrusion surrounding the combustor and oil conveying parts is formed on the upper surface of the horizontal partition plate. A recessed oil discharge port is provided at the open end of this U-shaped protrusion, and a wiring opening is provided on the outside of the U-shaped protrusion.

(Function) In the petroleum refrigerant heating/cooling device of the present invention, the interior of the outdoor unit main body is divided into two upper and lower chambers by a horizontal partition plate.
Since the heating unit and refrigeration cycle are placed in their own chambers, the entire device can be made more compact.
Additionally, the combustor and oil conveyance parts where oil leaks occur are surrounded by a U-shaped ridge provided on the horizontal partition plate, and the oil leaking from the combustor and oil conveyance part is passed through the wiring opening provided on the outside of the U-shaped ridge. Discharge the oil to the outside of the machine from the recessed oil outlet provided at the open end of the U-shaped protrusion to prevent it from getting on the wiring.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 indicates an outdoor unit main body of a petroleum refrigerant heating/cooling device, and the interior of this outdoor unit main body 1 is divided by a horizontal partition plate 2 into two upper and lower chambers. Cooling equipment such as a compressor 4, condenser 5, and cooling fan 6 are arranged in the lower chamber 3, and heating equipment such as a combustor 8, heater 9, and combustion fan 1O, as well as oil conveying equipment, are arranged in the upper chamber 7. A device 11 is arranged.

As shown in FIG. 3, the horizontal partition plate 2 has a U-shaped protrusion 12 whose overall shape is U-shaped or U-shaped on one end side of the upper surface.
is provided. This U-shaped protrusion 12 is connected to the horizontal partition plate 2
A region 13 is formed on the upper surface of the device to separate it from other parts. Further, in the opening 14 located at one side edge of this U-shaped protrusion 12, an oil discharge port 15 is formed as a recessed portion by a notch.

On the other hand, a wiring opening 16,17 and a piping opening 18 are formed on the upper surface of the horizontal partition plate 2 outside the U-shaped protrusion 12, and an exhaust pipe opening 19 is formed on the other end of the upper surface. It is formed. That is, on the horizontal partition plate 2,
An electromagnetic pump 20 and an oil strainer 21, which constitute the combustor 8 and the oil conveying device 11, are arranged in an area 13 partitioned by the U-shaped protrusion 12 shown in FIG.

In FIG. 1, reference numeral 22 is an exhaust vibrator, and this exhaust vibrator 22 is connected to the exhaust pipe opening 1 provided in the horizontal partition plate 2.
9 and is connected to an exhaust port (not shown) provided on the side wall of the outdoor unit main body 1 near the cooling fan 6 .

Since the electromagnetic pump 20 and oil strainer 21 constituting the combustor 8 and the oil conveying device 11 are arranged in the area 13 partitioned by the U-shaped protrusion 12 provided on the horizontal partition plate 2, the oil During maintenance and inspection of the refrigerant heating and cooling system, oil that leaks from the connection between the electromagnetic pump 20 and the oil strainer 21 or the connection between the combustor 8 and the oil pump, or oil that leaks due to repeated misfires of the combustor 8, is The oil that falls into the area 13 partitioned by the U-shaped ridges 12 is surrounded by the U-shaped ridges 12, so it does not flow in the direction of other equipment or wiring.
The oil collects in the area 13 partitioned by the U-shaped protrusion 12, and from there the oil discharge port 1 provided in the opening 14 of the U-shaped protrusion 12
5 and is ejected from the machine.

Further, since the U-shaped protrusions 12 provided on the horizontal partition plate 2 also act as reinforcing members, the plate thickness can be reduced.

〔Effect of the invention〕

As described above, according to the present invention, the inside of the outdoor unit main body is divided into two upper and lower chambers by a horizontal partition plate, and the heating unit parts such as the combustor, heater, and combustion fan are arranged in the upper chamber, and the lower chamber A refrigeration cycle unit such as a compressor, a condenser, and a cooling fan is disposed in the horizontal partition plate, and a U-shaped protrusion surrounding the combustor and oil conveying parts is formed on the upper surface of the horizontal partition plate.
A recessed oil discharge port is provided at the open end of this U-shaped ridge, and a wiring opening is provided on the outside of the U-shaped ridge, so that oil leaking from the equipment will fall into the area partitioned by the U-shaped ridge. The oil does not flow in the direction of other equipment or wiring, and is discharged from the area partitioned by the U-shaped ridges to the outside of the machine through the oil outlet provided at the opening of the U-shaped ridges, without contaminating other parts. In addition, the entire device can be made more compact.
Moreover, since the U-shaped protrusions provided on the horizontal partition plate act as reinforcing members, the thickness of the plate can be reduced and costs can be reduced.
