Abstract
The utility model relates to a forced-ventilated type gas water heater, comprising a shell, wherein a burner, a heat exchanger and an exhaust device are sequentially communicated and arranged in the shell from bottom to top. The utility model has simple structure, and can effectively reduce the working noise by arranging the reversing cavity.
Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a gas water heater.
[ background of the utility model ]
The existing forced-ventilated type gas water heater is generally characterized in that a smoke collecting hood is directly arranged above a heat exchanger to be connected with a smoke exhaust pipe to exhaust smoke, the smoke resistance of the water heater during working is small due to the structure, the heat loss is large, particularly, the mass flow of products exceeds more than 24L, the resonance noise is easy to occur, and the water heater cannot work in the case of outdoor strong wind. Later on, a structure of a forced-draft gas water heater appeared on the market, for example, the structure described in patent No. 202020953688.6, in which a fan is arranged above a burner to perform forced draft, in such a way, the size of the water heater is limited, a smoke exhaust channel is small, a high-power product cannot be used, and the smoke exhaust effect is not good.
[ Utility model ] content
The utility model aims to overcome the defects of the prior art and provides the forced-ventilated type gas water heater which is simple in structure, good in smoke exhaust effect, high in heat efficiency and capable of effectively reducing working noise.
In order to solve the problems, the utility model adopts the following technical scheme:
the utility model provides a forced-ventilated formula gas heater, includes the shell, the shell in from supreme intercommunication in proper order down be equipped with combustor, heat exchanger, exhaust apparatus, its characterized in that: the combustor lower extreme be equipped with the opening, the shell in still be equipped with air-out end and opening intercommunication and can produce the fan to exhaust apparatus air current from the combustor, exhaust apparatus including with the collection petticoat pipe of heat exchanger upper end intercommunication, connect at collection petticoat pipe lateral wall and with the switching-over chamber of collection petticoat pipe intercommunication, establish the chimney on switching-over chamber and vertical extension.
The forced-ventilated formula gas heater as above, its characterized in that: the side wall of the smoke collecting cover is provided with a communicating port, the reversing cavity comprises a vertical section extending vertically and a horizontal section arranged at one end of the vertical section, the chimney is arranged at the top end of the horizontal section, and the upper side end of the vertical section is connected and communicated with the communicating port.
The forced-ventilated formula gas heater as above, its characterized in that: the horizontal section is arranged above the smoke collecting hood and is relatively separated, and the smoke tube is arranged in the middle of the top end of the horizontal section.
The forced-ventilated formula gas heater as above, its characterized in that: the horizontal section is parallel to the upper end surface of the smoke collection cover.
The forced-ventilated formula gas heater as above, its characterized in that: the lower end opening of the fume collecting hood is internally provided with a positioning step, and the upper end of the heat exchanger extends into the lower end opening of the fume collecting hood and is pressed on the positioning step.
The forced-ventilated formula gas heater as above, its characterized in that: the width dimension of the horizontal section is more than 3 times larger than the height dimension of the horizontal section.
The utility model has the following beneficial effects: the fan sets up in the combustor below, can give exhaust apparatus more spaces like this, and the position of fan is in the side of proportional valve etc. the space that itself just exists, consequently, can not increase the space of water heater, exhaust apparatus makes the air current carry out one side switching-over through the switching-over chamber, waste gas becomes upwards from the side direction, can effectively increase the flue gas resistance, effectively solve the combustion noise problem, the burning produces the flue gas and can not once only directly discharge, reduce calorific loss, the thermal efficiency is improved, the wind of outside also can not directly flow backward into, the anti-wind ability is strengthened.
