Abstract
The utility model discloses a positive displacement gas water heater, which comprises a pressure-bearing water tank, a cold water inlet, a hot water outlet, a rapid heating device and a circulating pump, wherein the pressure-bearing water tank consists of an inner tank and an interlayer. The positive displacement gas water heater is characterized in that the rapid heating device is arranged at the bottom of the interlayer; the circular pump is arranged in a shell of the rapid heating device and is connected with a heater of the rapid heating device through a circulating pipe; the circulating pump is connected with the middle lower part of the inner tank through a circulating pipe; the heater is connected with the middle upper part of the inner tank through a circulating pipe; a flue gas pipeline on the rapid heating device passes through the inner tank and the interlayer and is communicated with the outside. The rapid heating device is arranged at the bottom of the interlayer, so the heating efficiency is increased in comparison to the conventional bottom heating; cold and hot water are layered due to the distribution of the circulating pipes, so that the consumption of energy is lowered, and the hot water draining time of the inner tank is prolonged.
Description
Technical field
The utility model relates to technical field of water heaters, is specifically related to outdoor volumetric gas water heater.
Background technology
As everyone knows, existing gas displacement type water heater is to place a burner a metal drum bottom, the bucket heart has a flue, the flue gas producing while burning for discharging, bucket surrounding is incubated with insulation material, burner combustion heats inner bucket water, and when water is heated to design temperature, temperature controller control combustion device stops burning.
Hot water after water heater heating on the market can mix with the cold water in tank body, be difficult to form obvious layering, user in use, can only be flowed out hot water the short time, the water flowing out is afterwards the water that cold water and hot water mix, and this mixing water temperature is difficult to arrive user's requirement.
The flue that is positioned at water heater is to be uprightly arranged on metal drum, the flue gas that burner produces when combustion process is directly discharged by pipeline, and the temperature of flue gas generally can reach 110 ℃-170 ℃, have objective heat, directly discharge can cause energy waste, also can cause environmental pollution simultaneously.
Utility model content
For above-mentioned deficiency of the prior art, the volumetric gas water heater that the utility model provides has solved traditional low problem of the water heater efficiency of heating surface.
In order to reach foregoing invention object, the technical solution adopted in the utility model is: a kind of volumetric gas water heater is provided, and it comprises press-bearing water tank, cooling water inlet, hot water outlet, nonstorage calorifier and circulating pump; Described press-bearing water tank is comprised of inner canister and interlayer; Described nonstorage calorifier is arranged on the bottom of interlayer, and circulating pump is arranged in the housing of nonstorage calorifier and is connected with the heater of nonstorage calorifier by circulation pipe; Described circulating pump is connected with the middle and lower part of inner canister by circulation pipe, and heater is connected with the middle and upper part of inner canister by circulation pipe; Flue on described nonstorage calorifier communicates with the external world through inner canister and interlayer.
Preferably, flue is positioned at that section of inner canister and is arranged in the shape of a spiral the middle and lower part of inner canister.
Preferably, described cooling water inlet is arranged on the lower end of inner canister through interlayer; Hot water outlet is arranged on the upper end of inner canister through interlayer.
The beneficial effects of the utility model are: the bottom that nonstorage calorifier is arranged on to interlayer, the more traditional bottom-heated efficiency of such setting is higher, the distributed architecture of circulation pipe makes hot and cold water layering, thereby has reduced energy consumption, and has extended the time that inner canister goes out hot water; Flue spirals in the middle and lower part of inner canister, has avoided flue to absorb heat from the hot water of top, has utilized fully the heat of flue gas.

1, hot water outlet; 2, circulation pipe; 3, flue; 4, interlayer; 5, nonstorage calorifier; 6, circulating pump; 7, cooling water inlet.
The specific embodiment
As shown in Figure 1, this volumetric gas water heater comprises press-bearing water tank, cooling water inlet 7, hot water outlet 1, nonstorage calorifier 5 and circulating pump 6; Described press-bearing water tank is comprised of inner canister and interlayer 4; Described nonstorage calorifier 5 is arranged on the bottom of interlayer 4, and the interior circulation pipe 2 that also passes through of housing that circulating pump 6 is arranged on nonstorage calorifier 5 is connected with the heater of nonstorage calorifier 5; Described circulating pump 6 is connected with the middle and lower part of inner canister by circulation pipe 2, and heater is connected with the middle and upper part of inner canister by circulation pipe 2; Flue 3 on described nonstorage calorifier 5 communicates with the external world through inner canister and interlayer 4.
The operation principle of this volumetric gas water heater is: the cold water of inner canister middle and lower part is pumped in nonstorage calorifier 5 by circulating pump 6, after heating, become hot water and enter into inner canister through circulation pipe 2, under the positive action of the strong air blast of the flue gas that nonstorage calorifier 5 discharges in nonstorage calorifier 5, send into flue 3, high-temperature flue gas is in inner canister during spiral helicine flue 3, can heat cold water, last flue gas is discharged through the top of press-bearing water tank again.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction of the protection domain to this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
