Description
- The present invention relates to an outdoor unit of an air-conditioning apparatus and an air-conditioning apparatus having the outdoor unit.
- In the outdoor unit of the air-conditioning apparatus, water droplets adhered to a front panel by rain or snow during a heating operation or water droplets generated by melting snow accumulated on the outdoor unit drop along a surface of the front panel and enter between a bell mouth and a fan.
- Then, when the outside temperature is low, the temperature of air blown out by the fan may drop to or below freezing. In such a case, the water droplets that entered between the bell mouth and the fan freeze and, if the quantity of the water droplets is large, ice grows and comes into contact with the fan. Accordingly, there arise problems such as generation of abnormal sounds, or abnormal stop of the outdoor unit due to hindrance of rotation.
- In order to solve the problems as described above, an outdoor unit for an air-conditioning unit in which a bell mouth having an outlet opening for a fan is formed on a casing, an outlet grill is provided on the front side of the bell mouth, and a seal member having a width larger than the diameter of the outlet opening is provided above the outlet opening for sealing a portion between the casing and the outlet opening is proposed (for example, see Japanese Registered Utility Model No.
2510078 Fig. 1 )). - In the outdoor unit for the air-conditioning unit disclosed in Japanese Registered Utility Model No.
2510078 Fig. 1 ), when sealing the portion between the casing and the top portion of the outlet grill with the sealing member, a frame-shaped rim is required on an outer periphery, or at least an upper side of the outlet grill formed by welding steel wires, so that the appearance design is not impaired and, in addition, it is necessary to combine a plate-shaped component to the steel wire portion. Therefore, there arise problems of complicated manufacture and increase in the cost. - In addition, since it is difficult to close a gap at a center portion with the sealing member only by fixing the same at both end portions of the outlet grill, fixing screws are added. This, however, aggravates the appearance and workability.
- In addition, only both end portions of the seal member are fixed in order to reduce the number of spots where the above-described seal member is fixed, while rattling or vibration is restrained by pushing an intermediate portion against the casing using the resiliency of the outlet grill. However, in such a case, since the both end portions are fixed in a state of being bent by the resiliency of the outlet grill itself, the seal member that seals the portion between the casing and the outlet grill is bent in a curve, so that it is difficult to ensure the sealing.
- In addition, since the sealing member requires a width substantially as large as the thickness thereof, a wall is formed at a position at least 10 mm below an upper surface of the outlet grill. Therefore, in order to decrease in the product size and improve the performance, the seal member is obliged to project toward an air course and hence impair the blowing operation of the fan specifically in the vicinity of the center portion on the upper side of the outlet grill because of the product design which requires maximizing of the fan diameter, which causes generation of noise and impairment of aerodynamic performance.
JP 8-178 365-A claim 1, but in which no appentice overhanging forward, so that a grill and bell mouth is sheltered from icicles or water droplets, is provided on the top panel. AndDE-20 2005 016 955-U1 discloses an outdoor unit comprising hoods at side faces of the unit for deflecting the air flows. - In order to solve the above-described problem, it is an object to the invention to provide an outdoor unit which is capable of reliably preventing water droplets from being frozen between a bell mouth and a propeller fan in a simple structure, and an air-conditioning apparatus having this outdoor unit.
- An outdoor unit according to the invention includes: a casing having a substantially parallelepiped shape opened on top; a top panel configured to close an opening on the top of the casing; a bell mouth provided at an outlet opening of a propeller fan formed on a front panel which constitutes the casing; and an outlet grill attached on the front side of the outlet opening; and it is characterized in that the top panel comprises an appentice at an edge portion thereof, at a portion corresponding to the outlet grill on the front side of the top panel so as to overhang forward from the edge portion.
- The air-conditioning apparatus according to the invention includes the outdoor unit described above.
- According to the invention, an outdoor unit which is capable of reliably preventing water droplets from being frozen between a bell mouth and a propeller fan in a simple structure without impairing the appearance, and an air-conditioning apparatus having this outdoor unit can be obtained.
- In an embodiment instead of the appentice, another appentice is provided over the entire edge portion on the front side of the top panel so as to overhang to the front from the edge portion.
- Advantageously the appentice overhangs from the edge portion on the front side of the top panel on the order of 10 to 20 mm.
- Advantageously the lower portion of the front end portion of the appentice is bent inward to form a bent portion.
- In an embodiment the overhung portion overhung on the order of several mm to 10 mm is formed on one of the side edge portions continuing to the appentice of the top panel via a shoulder and the side surface of the casing is formed into a shape corresponding to the overhanging portion of the front panel.
- In an embodiment screw insertion holes are formed at a plurality of positions, which includes positions in the vicinity of the apprentice, in a fitting portion provided on an outer periphery of the top panel, and screws inserted into the screw insertion holes are screwed into screw holes (10) provided on an engaging portion on a peripheral edge of an opening on the top of the casing, so that the top panel and the casing are integrally fixed.

In the description given below, the near side of the drawing is referred to as the front side, the far side of the drawing is referred to as the back side, the left side of the drawing is referred to as a left side surface and a right side of the drawing is referred to as the right side surface. - In
Fig. 1 to Fig. 4 ,reference numeral 1 designates a casing of the outdoor unit formed to have a parallelepiped shape opened on top by a bottomplate having legs 2a on a lower surface thereof, a substantially L-shaped front panel 3 mounted from the front side to the left side surface, aside panel 4 mounted from the right side surface to part of the back side, and a substantially L-shaped heat exchanger 5 mounted from the back side through the left side surface to the inside of thefront panel 3. An opening on the top is closed with atop panel 15. Although a partitioning panel, a compressor, refrigerant piping, and electric components are mounted in thecasing 1, these components are not illustrated. -
Reference numeral 30 designates a propeller fan whose driving motor (not illustrated) is attached to amotor mounting panel 6 extending upright from thebottom plate 2 in thecasing 1, abell mouth 7 is provided at an outlet opening of thepropeller fan 30 provided on thefront panel 3, and anoutlet grill 8 is attached to the outside of the outlet opening so as to cover the outlet opening. - Formed on upper end portions of the
front panel 3 and theside panel 4 is anengaging portion 9 slightly reduced in thickness via a shoulder 9a, andscrew holes 10 are provided on theengaging portion 9 corresponding toscrew insertion holes 19 formed on afitting portion 18 of thetop panel 15, described later. - The
top panel 15 is formed to have a size substantially the same as the outline of thecasing 1, and is provided with thefitting portion 18 configured to be fitted to theengaging portion 9 of thecasing 1 along the peripheral edge thereof except for anappentice 16 described below, a portion on the front side corresponding to theoutlet grill 8 is provided with anappentice 16 overhanging outward (to the front) from an edge portion. Although the amount of protrusion of theappentice 16 is described to be on the order of 10 to 20 mm from an edge portion in the embodiment, the invention is not limited thereto. Then, thefitting portion 18 is formed with a plurality of thescrew insertion holes 19 including a portion near theappentice 16. - The
appentice 16 is bent or curled inward into a substantially U-shape at a lower portion at a front end portion as shown inFigs. 6A and 6B , which are cross-sectional views taken along the line X-X inFig. 5 (hereinafter, this part is referred to as a bent portion 17). - Also, as shown in
Fig. 3 and Fig. 4 , an edge portion on the left side surface of thetop panel 15 continuing from theappentice 16 overhangs slightly (for example, on the order of several mm to 10 mm) from the surface of theappentice 16 on the left end portion thereof via ashoulder 21 to form anoverhanging portion 20. A side surface portion 3a of thefront panel 3 of thecasing 1 also has a shape corresponding to the overhangingportion 20 of thetop panel 15 via ashoulder 11. - The
top panel 15 configured in this manner is fitted at thefitting portion 18 thereof to theengaging portion 9 of thecasing 1 and closes the opening on the top of thecasing 1, then is fixed integrally therewith by screwing screws inserted into the plurality ofscrew insertion holes 19 formed on thefitting portion 18 of thetop panel 15 respectively into thescrew holes 10 formed on theengaging portion 9 of thecasing 1 corresponding to thescrew insertion holes 19. At this time, theappentice 16 provided on thetop panel 15 above theoutlet grill 8 projects from the surface of thefront panel 3 to the front surface side until a position in the vicinity of a front edge portion of theoutlet grill 8. - In this case, since the
outlet grill 8 is positioned on the left side of thecasing 1, if the left edge portion and the left end surface of theappentice 16 of thetop panel 15 are flush with each other and this part is formed to be linear, thetop panel 15 may be displaced in the fore-and-aft direction at the time of assembly of the product and hence thescrew insertion holes 19 are not aligned with thescrew holes 10, whereby workability may be deteriorated. - In this embodiment, the left edge portion of the
top panel 15 is formed with the overhangingportion 20 overhanging slightly from the left end surface of theappentice 16 via theshoulder 21 provided therebetween and the side surface 3a of thefront panel 3 of thecasing 1 is formed into a shape corresponding to the overhangingportion 20 via theshoulder 11. Therefore, positioning in the fore-and-aft direction of thetop panel 15 at the time of assembly is ensured, so that workability can be improved. - In the outdoor unit according to this embodiment having the configuration as described above, when water droplets adhered on the
top panel 15 or melted snow accumulated on thetop panel 15 flows out toward the front surface, the water droplets flow along thefront panel 3 on the right side in the drawing but, on the side of the outlet grill 8 (the left side), water droplets drop at positions away from the surface of thefront panel 3, come into contact with the lower portion of thefront panel 3 or bridges of theoutlet grill 8, and drop along the bridges because thetop panel 15 is provided with theappentice 16. Therefore, icicles generated by freezing grow on the bridges of theoutlet grill 8 and enter neither thefront panel 3 nor thebell mouth 7. - Therefore, even when the outside air temperature is low and the blown air temperature from the
propeller fan 30 drops to or below freezing, no freezing occurs between thebell mouth 7 and thepropeller fan 30, and generation of abnormal sound of thepropeller fan 30 due to the freezing can be prevented. - Also, since the front end portion of the
appentice 16 of thetop panel 15 is located at a position away (protruded) from thefront panel 3, the user often places his or her finger on theappentice 16. Since thebent portion 17 formed by being bent inward is provided at the lower portion of the distal edge portion of theappentice 16, injury of a finger is prevented and safety can be secured. - The
top panel 15 is fixed by the screws inserted into the screw insertion holes 19 provided at a plurality of points on thefitting portion 18 including the positions in the vicinity of theappentice 16 screwed into the screw holes 10 formed correspondingly on the engagingportion 9 of thecasing 1. Therefore, even when a force in the direction of lifting theappentice 16 with the hand thereon is applied, deformation of theappentice 16 can be prevented. -
Fig. 7 is a perspective view illustrating a state in which the top panel of the outdoor unit of the air-conditioning apparatus according toEmbodiment 2 of the invention is removed. The identical or same functional portions as inEmbodiment 1 are designated by the same reference numerals. - In
