Description
Technical Field
The present invention relates to an outdoor unit of an air conditioner, and more particularly, to a structure for introducing outside air into a machine room.
Background
Conventionally, in an outdoor unit of an air conditioner, a panel constituting an outer periphery of a machine room is provided with a vent hole. The temperature rise of the electric component is suppressed by the outside air sucked from the air vent. However, there is a fear that rainwater or the like enters together with air sucked through the air vent. Water enters the machine chamber, and thus moisture adheres to the electrical components, which may cause short-circuiting of the circuit, leakage of electricity, and ignition. In addition, moisture may adhere to a refrigerant container provided inside the machine chamber, and rust may be generated and deteriorate. If the refrigerant container is degraded, there is a concern that the refrigerant may leak from the refrigerant container.
According to patent document 1, a ventilation port is provided in a panel constituting an outer periphery of a machine room, and an inner panel for preventing water from entering is provided inside the ventilation port. The inner panel is attached to the panel constituting the outer frame from the inside, and is arranged parallel to the panel provided with the air vent.
Patent document 1: japanese patent laid-open No. 2006-84106
When taking measures such as installing an internal panel inside a machine room or installing an insulator on an electric component, as in the outdoor unit of the air conditioner disclosed in patent document 1, the number of assembly steps increases, which is an important factor in increasing the cost of the product. Further, since the lower end portion of the inner panel is located below the lower end of the air vent, the air introduced from the air vent flows downward along the inner panel, and therefore, the air for cooling the electric components disposed in the upper portion of the machine room does not reach sufficiently, and there is a problem that the cooling of the electric components cannot be sufficiently performed.
SUMMERY OF THE UTILITY MODEL
The present invention has been made to solve the above problems, and an object of the present invention is to provide an outdoor unit of an air conditioner that prevents water from entering from the outside and reaching electrical components while ensuring air for cooling the electrical components installed in the upper portion of a machine room.
The utility model relates to an air conditioner's off-premises station is the off-premises station of air conditioner that possesses heat exchanger, outdoor fan, compressor and electrical component in the inside of casing, possesses: a main air passage in which the outdoor fan and the heat exchanger are arranged; and a machine room in which the compressor and the electric component are arranged, wherein the casing includes a machine room-side panel that constitutes a side surface of an outer shell of the machine room, and the machine room-side panel includes: a vent through which external air flows into the machine chamber; and a shielding portion extending obliquely downward toward an inner side of the machine chamber, wherein the shielding portion is located inside the air vent, and the electric component is disposed above the shielding portion.
Further, the following configuration is possible: the machine room side panel includes: an upper panel that constitutes a side surface of an outer contour of a portion where the electric component is arranged; and a lower panel combined with the upper panel below the upper panel, wherein the vent is provided in the lower panel, and the shielding portion is provided at a lower end of the upper panel.
Further, the following configuration is possible: the lower end of the shielding portion is located above the lower end of the vent hole.
Further, the following configuration is possible: the vent is provided with: an opening portion provided in a direction perpendicular to the machine chamber side panel; and a guide portion extending downward from an upper end of the opening portion to cover the opening portion, wherein an air inlet is formed by a lower end of the guide portion and a lower end of the opening portion, and the air inlet is open downward.
Further, the following configuration is possible: the electric component is located above an imaginary plane passing through a lower end of the air vent and a front end of the shielding portion.
According to the outdoor unit of an air conditioner of the present invention, with the above configuration, the entry of water into the mechanical chamber can be suppressed without adding a member for shielding the vent port from the inside, and the water can be suppressed from reaching the electrical component.

Detailed Description
Embodiment 1.
Hereinafter, an embodiment of the outdoor unit 100 of the air conditioner will be described. The form of the drawings is an example, and does not limit the present invention. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and this is common throughout the specification. In the following drawings, the relationship between the sizes of the respective components may be different from the actual one.
< overall construction of outdoor unit 100 >
Fig. 1 is a perspective view of an outdoor unit 100 of an air conditioning apparatus according to embodiment 1. The casing 1 of the outdoor unit 100 of the air conditioner includes a top panel 2, an air path front panel 3, a machine room front panel 4, and a back panel 5. The machine room front panel 4 is composed of a machine room upper front panel 4a and a machine room lower front panel 4 b. The rear panel 5 is composed of an upper panel 5a and a lower panel 5 b.
Fig. 2 is a perspective view illustrating an internal structure of the outdoor unit 100 of the air conditioner of fig. 1. Fig. 3 is a front view illustrating an internal structure of the outdoor unit 100 of the air conditioner of fig. 1. Fig. 2 shows a state where the top panel 2, the air path front panel 3, the machine room front panel 4, and the rear panel 5 are removed from the casing 1. The inside of the case 1 includes: a main air passage 30 in which an outdoor fan 8 and a heat exchanger 7 are disposed; and a machine chamber 20 in which the compressor 11 and the electric component 12 are disposed. The machine room 20 and the main air passage 30 are partitioned by a partition 10.
The main air duct 30 takes in outside air from the back side of the casing 1 and discharges the air from the front side. A fan shroud 31 is provided on the front side of the main air passage 30. The outdoor fan 8 is fixed in the main air passage 30 via a fan motor fixing metal plate 9. The fan motor fixing metal plate 9 is fixed to the bottom plate 6 forming the bottom of the case 1. The heat exchanger 7 is disposed over the entire area of the air intake port located on the rear side of the main air passage 30.
The machine chamber 20 includes a compressor 11 and an electric component 12. A compressor 11 is provided in a lower portion of the machine chamber 20. The compressor 11 is disposed on the bottom plate 6 forming the bottom of the casing 1. Although not shown in fig. 2, refrigerant pipes connected to the compressor 11 are also disposed around the compressor 11. An electric component 12 for controlling operations of the compressor 11, the outdoor fan 8, and the like is disposed above the machine room 20. The electric components 12 generate heat when the outdoor unit 100 of the air conditioner is operated, and therefore need to be cooled.
In embodiment 1, the machine room 20 has an outer contour whose side surfaces are formed by the machine room front panel 4 and the rear panel 5. The panels constituting the side surfaces of the outer shell of the machine room 20, such as the machine room front panel 4 and the machine room rear panel 5, are collectively referred to as machine room side panels. Since the electrical component 12 and the compressor 11 are provided inside the machine chamber 20, it is necessary to suppress the intrusion of water into the interior as much as possible. When moisture adheres to the compressor 11, the refrigerant may be deteriorated due to rust and may leak from the refrigerant circuit. Further, if moisture adheres to the electrical component 12, short-circuiting of the circuit, heat generation, and ignition may occur. However, when the outdoor unit 100 is operated, the electric components 12 generate heat, and therefore, cooling is required. Therefore, the air vent 50 that takes outside air into the inside and sends the air to the electrical component 12 is provided in the outer periphery of the machine chamber 20.
Fig. 4 is a side view of the outdoor unit 100 of the air conditioning apparatus of fig. 1, as viewed from the machine room 20 side. A vent 50 is provided on a side surface of the outer periphery of the machine chamber 20. The air vent 50 is provided in the lower portion of the machine chamber 20, and in embodiment 1, is provided in the lower side panel 5b of the rear panel 5.
Fig. 5 is a perspective view of an upper panel 5a of the rear panel 5 of the outdoor unit 100 of the air conditioning apparatus according to embodiment 1. The upper panel 5a forms an outer contour of the rear surface side of the upper side surface of the machine room 20. The upper panel 5a is combined with the top panel 2, and the lower panel 5b is combined with the lower panel. The front side is combined with the machine room upper front panel 4 a. The adjacent panels are configured to overlap each other at the end portions so that water and dust do not enter the interior.
The upper panel 5a includes the shielding portion 14 at the lower end 54. The shielding portion 14 is disposed to extend obliquely downward toward the inside of the machine chamber 20. The shielding portion 14 is provided to protrude further downward from a portion overlapping when the upper panel 5a and the lower panel 5b are combined, and thus to enter the rear side of the lower panel 5 b. In particular, the shielding portion 14 is disposed to extend to the rear side of the ventilation port 50 provided in the lower panel 5b when viewed from the outside of the outdoor unit 100.
Fig. 6 is a perspective view of the lower panel 5b of the back panel 5 of the outdoor unit 100 of the air conditioning apparatus according to embodiment 1. The lower panel 5b is provided with an air vent 50 on its side surface. The air vent 50 is provided on the side surface side when the outdoor unit 100 of the air conditioner is viewed from the front. In embodiment 1, the ventilation port 50 is provided in the lower side panel 5b of the rear panel 5, but may be provided in, for example, the machine room lower side front panel 4b as long as air can be introduced into the machine room 20. However, the structure of the vent 50 needs to have the structure described below.
Fig. 7 is a view showing a Z-Z section of fig. 4. The cross-sectional structure of the vent 50 will be described with reference to fig. 7. The shielding portion 14 provided to extend obliquely downward toward the inside of the machine chamber 20 from the lower end portion 54 of the upper side panel 5a enters the lower side panel 5b and is located inside the machine chamber 20 with respect to the vent 50. The upper end 53 of the lower panel 5b overlaps the lower end 54 of the upper panel 5 a. Therefore, water and dust are inhibited from entering from the mating portion of the upper panel 5a and the lower panel 5 b.
The lower side plate 5b has an opening 51 formed in a direction perpendicular to the side surface of the housing 1. The opening 51 is covered with the guide 13 and is not visually recognized when viewed from the side of the housing 1. An air inlet 52 is formed by the lower end of the opening 51 and the lower end of the guide 13. That is, air is taken in from the gap between the lower end of the opening portion 51 and the lower end of the guide portion 13. The guide portion 13 is configured to extend downward from the upper end of the opening 51, and thus the air inlet 52 is formed to face downward. With this configuration, rainwater falling mainly from above is prevented from entering the inside, and outside air is allowed to enter from the air inlet 52.
Further, since the air inlet 52 of the air vent 50 is directed downward, even if air having a high flow velocity enters the air vent 50 due to strong wind or the like, the flow velocity is attenuated. Further, since the shielding portion 14 is located inside, the flow velocity of air is attenuated by the abutment thereof. Therefore, the air flowing into the air vent 50 is decelerated and enters the machine chamber 20, and thus diffusion of external dust and the like into the machine chamber 20 is suppressed.
The front end of the shielding portion 14 is located above the lower end of the air vent 50. With such a configuration, the shielding portion 14 can ensure air to be supplied to the electrical component 12 located above while decelerating the air flowing in from the air vent 50. That is, as shown by an arrow 18 in fig. 7, the air flowing in from the vent 50 flows while bypassing the shielding portion 14 after coming into contact with the shielding portion 14. Further, the electric component 12 is located above an imaginary plane passing through the lower end of the air vent 50 and the front end of the shielding portion 14, and therefore does not come into contact with water droplets flowing into the machine room 20 together with air.
The machine room 20 includes an air passage that is fluidly connected to the air flow of the main air passage 30, and is configured to introduce the air inside the machine room 20 into the main air passage 30. The air passage is disposed near the electrical component 12, and is configured to allow air inside the machine room 20 to flow into the main air passage 30 through the electrical component 12, thereby actively cooling the electrical component 12.
With the above configuration, the outdoor unit 100 of the air conditioner can secure air for cooling the electrical components 12 through the air vents 50 and suppress moisture entering from the outside from reaching the electrical components 12. Therefore, not only short circuit, electric leakage, and ignition of the electrical components 12 in the machine room 20 can be suppressed, but also deterioration of the compressor 11 due to rust can be suppressed. Further, since the air flowing in from the air vent 50 can be decelerated by abutting the shielding portion 14, dust and the like entering the machine chamber 20 are not diffused inside.
