Abstract

The utility model relates to a water storing type gas water heater. A water storing barrel which is provided with a heat preserving layer is arranged in a shell. Bottom of the barrel forms an airproof burning room which is used for laying groups of burners. A controlling device which is arranged on the outside of the shell is inserted into the burning room by a gas pipe. Top of the shell is beforehand provided with an air discharging mechanism to controlling an in-exhausting pipe so as to make the entered gas inserted through the space between the shell and the heat preserving layer and adhibited in the burning room. A plurality of hollow and wave-shaped exhausting heat absorbing pipes are arranged in the barrel and whose one end directs to the air discharging mechanism and educed out by the exhausting pipe, while the other end leads to the lower burning room and makes the heat pass through the exhausting heat absorbing pipes. The utility model has low height, which perfectly suits for being installed indoors.

Description

The storage water heater gas water heater

The relevant a kind of storage water heater gas water heater of the utility model.

Must make coal gas mix a large amount of air during the gas water heater burning, but the gas water heater of the open combustion chamber of tradition employing is to make to suck air or discharge the direct and surrounding air convection current of air, its prerequisite promptly is to possess good ventilated environment.But this type of conventional water heaters is installed in causes coal gas not have outward in the narrow interior space or incomplete combustion causes that carbon monoxide poisoning event still takes place repeatedly.Though existing Improvement type gas water heater has the drawback of forced exhaust mechanism to prevent that indoor installation from being caused, its effect is still not satisfactory.

In addition, traditional positive displacement gas water heater and interior center are provided with single upright heat absorption blast pipe and carry out the tube wall heat absorption, and this traditional displacement type water heater is bulky, and is not suitable for indoor installation.

The purpose of this utility model is to provide a kind of storage water heater gas water heater, and this water heater can be installed in the interior space, and can significantly dwindle the suitable whole height of hot water.

For this reason, the utility model provides a kind of gas water heater, be provided with an insulation laminar water butt in a casing inside, and bottom of shell forms an airtight combustion chamber for inserting many group burners: then default air draft mechanism is for the air inlet-outlet pipe of control directed outwards along the casing top; A plurality of hollow waveform exhaust endothermic tubes then are located at above-mentioned water butt inside, make the end guiding top air draft mechanism of these waveform exhaust endothermic tubes, the other end then leads to the combustion chamber, below, waste-gas heat behind the burner combustion of group more than the making coal gas is via air draft mechanism and relevant air inlet system and exhaust system, and can guide by these waveform exhaust endothermic tubes, thereby form a kind of pressure intake and exhaust and significantly dwindle volume height, and the spy is fit to be installed in indoor storage water heater gas water heater.

Preferred embodiment is described following conjunction with figs. to the utility model, to further specify its characteristics and advantage; Wherein:

Fig. 1 is the utility model preferred embodiment stereogram;

Fig. 2 is the cutaway view of Fig. 1 embodiment;

Fig. 3 is the inside water butt of Fig. 1 embodiment and the stereogram of relevant exhaust blower thereof;

Fig. 4 is the exhaust gas inside endothermic tube of Fig. 3 embodiment and the stereogram of bottom combustion chamber thereof;

Fig. 5 is a bottom combustion chamber cross section bottom view; And

Fig. 6 is the workflow diagram of Fig. 1 embodiment.

As shown in Figure 1, 2, the utility model water heater is provided with a casing 10, and its top has an outer cover 11, one side external surfaces and then is provided with a control device 20 in internal preset solenoid valve for gas and associated electrical controller.

Casing 10 inside are provided with a water butt 30, and water butt 30 peripheries packing refractory ceramics heat-insulation layer 31.This heat-insulation layer 31 also extends 12 formation, one combustion chamber 40, cooperation casing 10 bottom surfaces downwards, and can be in burner 41 wherein is set.20 of control device are provided with a female kindling tracheae 21 and a plurality of main kindling tracheae 22, and illustrated embodiment makes main kindling tracheae 22 by in the external fire burns of the casing chamber 40, and makes its jet for gas 23 towards each burner 41 for three groups of burners 41 of supply.

A plurality of waveform hollow exhaust endothermic tubes 50 then are located at water butt 30 inside, and these exhaust endothermic tube 50 upper ends 51 are with the inlet of a conduit 60 connection outer covers 11 inner exhaust blowers 70, and its lower end 52 is 40 the burner 41 Waste gas outlet positions towards the combustion chamber then.

Can install a cold water inlet 13 and a hot water outlet pipe 14 respectively along between casing 10 and water butt 30 tops, outer cover 11 then installs one than the air inlet pipe 15 of big footpath with exterior, make introduce air can be by sending into casing 10 by air inlet 16, again by heat-insulation layer 31 and casing 10 corner passage between the two, and deliver in the combustion chamber 40, and mix with coal gas and burn in burner 41 1 ends by bottom blow vent 17.Another 18 of blast pipe being located at air inlet pipe 15 inside leads to the casing outside equally, and make one be connected to the outlet of exhaust blower 70, making that below burner 41 burning coal gas are waste gas produced can be via waveform hollow exhaust endothermic tube 50, conduit 60 and exhaust blower 70, and discharges from blast pipe 18.

Shown in Fig. 3,5, in the diagram preferred embodiment, a water butt 30 cylindraceous and a side are to form air duct between the polygonal casing 10, make the above-mentioned air that is imported by air inlet pipe 15 introduce combustion chamber 40 by blow vent 17.And this combustion chamber 40 preferably is divided into one for the compartment 42 of putting into many group burners 41 with exotic material, and forms the circuit 43 of a direct air.

As shown in Figure 6, the control device 20 main actions of being located at casing 10 outer surfaces are valve and the opening power of turning on the gas-fire, and with thermometer induction design temperature.When water butt 30 water temperatures are low, then make exhaust blower 70 rotate exhaust, with relative introducing air, light female fire, inductive rod confirms to open the big fire heating, hot waste gas after burner 41 burning is introduced by the lower end 52 of a plurality of waveform hollow exhaust endothermic tubes 50, sent through exhaust blower 70 and blast pipe 18 by its upper end 51 again.

The combustion system of the utility model gas water heater is removed because of forcing the balance intake and exhaust, makes intake and exhaust all stretch out the indoor anoxic of outdoor release, and that the spy is suitable for being installed in is indoor, and airtight combustion chamber also can reduce thermal loss.A plurality of waveform hollow exhaust endothermic tubes of being located at water butt inside simultaneously also can strengthen endotherm area and reduced height relatively, make the height of whole gas water heater dwindle 2/3rds than traditional type.
