CN2344706Y - Air exhauster for water heater - Google Patents

Abstract

The utility model relates to an air exhauster for water heaters, which mainly comprises an upper cover, wherein the upper cover is provided with air outlets in the upward direction and both the side directions. The predetermined position in the upper cover is provided with a flow guide plate which is corresponding to the heat radiating fin assembly of the water heater. The flow guide plate is arranged on one side of the opening edge of the air exhaust opening of a middle partition plate which is correspondingly covered on the top surface of the heat radiating fin assembly. Through the position of the air exhaust opening of the middle partition plate and the flow guide direction of the flow guide plate on the opening edge of the air exhaust opening, the hot air exhaust is effectively aided, the utility model prevents the ambient air of the water heater from disordered flow to inversely enter the water heater along the air outlets of the upper cap and the normal combustion of the gas ejected by a fire grate is affected.

Description

The water heater air exhausting device

The utility model relates to a water heater, particularly relevant for a kind of air exhausting device of water heater.

Conventional water heater air exhausting device, it mainly is to establish a tool upward to the loam cake of exhaust outlet in the end face one of the groups of fins of water heater lid, but the application space in this loam cake independently is provided with some deflectors more in addition, so will make being provided with of deflector zero scattered diffusing, and the diversion Design of this deflector considers it mainly is the waste gas that will consider gas combustion in the guide water heater smoothly, moreover need take into account again and prevent that water heater surrounding air sinuous flow is along contrary go in the water heater of the air outlet of this loam cake and the gas normal combustion of influence fire row ejection; Offer the auxiliary exhaust mouth in the loam cake both sides and in traditional water heater, also have, water heater air exhausting device at this kind space kenel, the deflector of being located in it just more need be considered the contrary wind from the side-exhaustion mouth, also so promptly increased the complexity that the deflector in the loam cake is provided with, that is the independent deflector quantity that is provided with certainly will increase, difficulty reaches the conforming degree of accuracy so the guide flow path of this deflector is controlled, and deflector is provided with the also more complicated raising manpower of processing time cost.

The purpose of this utility model is to propose a kind of water heater air exhausting device of being made up of loam cake, deflector, radiator group and median septum, it not only can effectively discharge hot gas, and can prevent water heater surrounding air sinuous flow and along contrary go in the water heater of this loam cake air outlet and the normal combustion of influence fire row ejection gas, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it comprises that mainly one upwards and to two side directions all has the loam cake of air outlet, and the preposition place establishes the deflector of corresponding water heater groups of fins in this loam cake; Wherein this deflector is exhaust outlet peristoma one side that is formed on the median septum that a corresponding groups of fins end face covers, the effective accessory hot air discharge by the design of the exhaust outlet position on this median septum and the deflector water conservancy diversion direction on the exhaust outlet peristoma, and prevent that water heater surrounding air sinuous flow is along contrary go in the water heater of the air outlet of this loam cake and the gas normal combustion that influence fire row sprays.

Fig. 1 is a perspective exploded view of the present utility model.

Fig. 2 is the organigram of vertically analysing and observe of the present utility model.

Fig. 3 vertically analyses and observe and the guide flow path schematic diagram for second embodiment's of the present utility model.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.See also Fig. 1 to shown in Figure 3, water heater air exhausting device of the present utility model, it has comprised that mainly one upwards and to two side directions all has the loam cake 10 of air outlet 100, the preposition place establishes the deflector 121 of corresponding water heater groups of fins 11 in this loam cake 10; And structure spirit wherein partly is: wherein this deflector 121 is exhaust outlet 120 peristomas one sides that are formed on the arch median septum 12 that corresponding groups of fins 11 end faces cover, certainly the be provided with exhausted air quantity and the waste gas that all produce for gas combustion in the water heater after tested of this each exhaust outlet 120 have smooth and easy exhaust effect to consider through the gesture of groups of fins 11 discharges, so and exhaust outlet 120 positions on this median septum 12 of mat and the design of the deflector 121 water conservancy diversion directions on exhaust outlet 120 peristomas and effective accessory hot air discharge, and prevent that water heater surrounding air sinuous flow is along contrary go in the water heater of the air outlet 100 of this loam cake 10 and the gas normal combustion of influence fire row ejection, wherein the deflector 121 on these each exhaust outlet 120 peristomas is in promptly deflector 121 must be formed at the side of exhaust outlet 120 peristomas near this air outlet 100 near loam cake 10 side air outlets 100, and exhaust outlet 120 is located at the top air outlet 100 of close loam cake 10, a then relative side that deflector 121 must be formed at close this top air outlet 100 of these exhaust outlet 120 peristomas, so can be effectively with internal waste gas to air outlet 100 direction water conservancy diversion, and stop along air outlet 100 to enter in the water heater, guarantee the normal combustion of gas in the water heater against the air sinuous flow of going into.

The above-mentioned structure design of mat, water heater air exhausting device of the present utility model, because these complicated a plurality of deflectors 121 are being formed on the median septum 12 by standard already, so can effectively water conservancy diversion waste gas and anti-blocking sinuous flow once be done accurate design against the problem of going into, and only need once can with these median septum 12 positioning instants to desire in the space of 11 of in water heater loam cakes 10 and groups of fins device this a plurality of deflectors 121, assembling fast, significantly it can effectively save the manpower time cost of assembling processing, meet economic benefit, and a standard forms the related angle of each deflector 121 on median septum 12, the accuracy of its guide flow path is easier to control, and the quality superiority that can be consistent in each unit has effectively overcome above-mentioned dust head owing to do not attain the perfect many shortcomings that produce in the structure design.

In sum, water heater air exhausting device of the present utility model, it has the considerable practicality effect that meets economic benefit and air draft quality superiority more easy to control, and progressive is obvious, the value between the enhancement industry.

Claims (1)

1. water heater air exhausting device, it comprises that mainly one upwards and to two side directions all has the loam cake of air outlet, the preposition place establishes the deflector of corresponding water heater groups of fins in this loam cake; It is characterized in that: wherein this deflector is exhaust outlet peristoma one side that is formed on the median septum that a corresponding groups of fins end face covers.
