Abstract

The utility model relates to a component installed on the air flue outlet end of an air flue type water heater, which comprises a top cap, an outer cylinder and an inner cylinder, wherein, the outer cylinder is sheathed outside the inner cylinder, and a gap is left between the inner wall of the outer cylinder and the outer wall of the inner cylinder. The top cap is connected with the upper end of the outer cylinder by a connecting piece. The top cap and the outer cylinder of the utility model can efficiently prevent falling rain and snow from falling into the inner cylinder, can avoid the failure of the water heater caused by that rain or snow enters the water heater along the air flue. Furthermore, because the outer cylinder is provided with air exhaust ports which are mutually staggered and the upper end of the inner cylinder is higher than the upper end of the outer cylinder, the anti-downdraught ability of the utility model is comparatively strong. The utility model is a sleeve type wind cap for a water heater, which can efficiently prevent the influence of wind or rain or snow.

Description

The telescopic blast cap of water heater

The utility model is mounted in parts on water heater flue outlet top.

Existing Flue Gas Water Heater all directly communicates its flue when installing with the outside, when blowing when running into, raining or snowing, can produce in various degree influence to the smoke evacuation of water heater, can cause the flame-out of water heater when serious, even the life security that jeopardizes the user, this makes numerous manufacturers and user thereof feel insecure and at a loss what to do.

The purpose of this utility model is to avoid above-mentioned phenomenon to take place and a kind of telescopic blast cap of water heater that can prevent wind, rain, snow influence effectively is provided, and it is simple in structure, and is easy to manufacture, safe and reliable.

Structural representation of the present utility model as shown in drawings, include top cover (1), urceolus (2), inner core (3), urceolus (2) is sleeved on the outside of inner core (3), leave the space between the outer wall of the inwall of urceolus (2) and inner core (3), top cover (1) is connected the upper end of urceolus (2) by connector (4).

Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing:

Structural representation of the present utility model as shown in Figure 1, include top cover (1), urceolus (2), inner core (3), urceolus (2) is sleeved on the outside of inner core (3), leave the space between the outer wall of the inwall of urceolus (2) and inner core (3), top cover (1) is connected the upper end of urceolus (2) by connector (4); Above-mentioned top cover (1) is made into curve form, Figure 1 shows that by the sphere and the conical surface to constitute; The upper end of above-mentioned inner core (3) exceeds the upper end of urceolus (2), and urceolus (2), inner core are respectively arranged with some groups of exhaust openings on (3), wherein inner core (3) is provided with 4 uniform rectangle exhaust openings, urceolus (2) is provided with uniform 4 groups of exhaust openings (5), and exhaust opening (5) is gone up set exhaust opening interlaced arrangement with inner core (3), and every group of exhaust opening (5) is made up of 3 rectangle holes.

The utility model in use, inner core (3) and water heater flue outlet top are joined, then the flue gas of water heater discharge upwards flows into inner core (3) along flue, wherein part of smoke goes up 4 uniform rectangle exhaust openings discharges through inner core (3), enter the passage between inside and outside tube, flue gas rises along this passage, and discharges from the open spaces between urceolus (2) and top cover (1); Another part flue gas rises along inner core (3), and from its open-ended overflowing, the open spaces through between urceolus (2) and top cover (1) is discharged again.

The utility model is owing to adopt the structure that is provided with urceolus and top cover outer tube, and therefore, when raining or avenge, top cover and urceolus can prevent effectively that the rain and the snow that fall from falling into inner core, avoids rain or snow to enter water heater along flue, and water heater can't be worked; In addition, because of being equipped with exhaust opening on the inside and outside tube, and stagger mutually, so when blowing, opening on the urceolus wall can obviously weaken the blast district that urceolus forms, the air-flow that enters from the urceolus opening then streamed along the inner core surface, and the passage between other opening from the urceolus and inside and outside tube flows out; In addition, because the upper end of inner core exceeds the upper end of urceolus, enter inner core from the top so can obviously weaken extraneous air-flow, its preventing air reverse flow ability is stronger, the utility model is a kind of simple in structure, convenient and practical, can prevent the telescopic blast cap of water heater of wind, rain, snow influence effectively.
