Abstract
The utility model relates to a heat increasing device for water heaters, which comprises a variable cross-section pipeline type cold water inlet negative-pressure suction loop and a hot water outlet loop, wherein, the variable cross-section pipeline type cold water inlet negative-pressure suction loop comprises a cold water inlet joint, a conical shrinking horn cavity, a cylindrical choke, a cylindrical stable flowing section, a negative-pressure cavity, a conical diffusing horn cavity, a cold water pipeline, and a cold water pipe joint connected with a water heater; the hot water outlet loop comprises a hot water pipe joint connected with the water heater, a hot water pipeline, a split flow cavity and a hot water outlet joint; the two ends of a negative-pressure pipeline are respectively connected with the negative-pressure cavity and the split flow cavity. When water flows in the heat increasing device for water heaters, a part of hot water can be heated by the secondary circulation to realize that the heat of the discharge water is improved under the condition of the unchanged capacity of an original water heater.
Description
The utility model relates to the heat-increasing device that is used for water heater.
What adopt in known water heater is by control valve, and heat exchanger, cold water pipe joint, pipe joint of hot water etc. are formed.Owing to adopt this structure, cold water flows in heat exchanger, be certain heat time heating time, and the temperature rise of Gu Shui just has been subjected to certain limitation, and especially when using winter, when the temperature rise of water during greater than 40 ℃, hot water flow is just very little, far can not satisfy instructions for use.
The purpose of this utility model is to install a heat-increasing device on former water heater additional, when cold water flows in this device, adopt varying-arca channel formula cold water water inlet negative pressure to suck the loop, the part hot water of the heat exchanger heats in water heater is drawn in the negative pressure cavity of this heat-increasing device, make this partly hot water and cold water mix, again through the heat exchanger post bake, because partly hot water secondary cycle heating, increased this part water in the heat exchanger heats time, thereby realized under the constant situation of former water heater capacity, improving leaving water temperature.
Technical solution of the present utility model is: install a heat-increasing device additional between the cold water pipe joint of former water heater and pipe joint of hot water, it is characterized in that having a varying-arca channel formula cold water negative pressure to suck loop and a hot water effluent loop in its main body.The front end that varying-arca channel formula cold water negative pressure sucks the loop has a conical horn chamber that shrinks, coupled have a cylindrical restriction, there is a cylindrical steady flow section at the restriction rear portion, cylindrical steady flow section is connected with negative pressure line, the cavity of junction is a negative pressure cavity, there is a conical diffusion horn chamber at the rear portion of cylindrical steady flow section, with taper shape diffusion horn chamber is back-connected a cold water pipeline arranged, what be connected with the cold water pipeline is the cold water pipe joint that connects water heater, the front end in hot water effluent loop has a pipe joint of hot water that connects water heater, and coupled have a hot water line, hot water line's front end is connected with negative pressure line, the cavity of junction is the shunting chamber, hot water line's rear end is connected with hot water effluent's joint.
Routine accompanying drawing has been described an embodiment of the present utility model down.
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is that the A of Fig. 1 is to cutaway view.
With reference to Fig. 1, Fig. 2, the heat-increasing device of water heater is to be the cold water water supply connector (1) that gas thread constituted by front end, it in the end the conical horn chamber (2) that shrinks, with its tightly be connected for cylindrical restriction (3), cylindrical restriction (3) rear portion is a cylindrical steady flow section (4), cylindrical steady flow section (4) is connected with negative pressure line (13) quadrature, constitute negative pressure cavity (5), the rear portion of cylindrical steady flow section (4) is conical diffusion horn chamber (6), back-connected with taper shape diffusion horn chamber (6) is cold water pipeline (7), vertical what be connected is the cold water pipe joint (8) that connects water heater with cold water pipeline (7), the end place of cold water pipeline (7) is cold water plug (15), connect the pipe joint of hot water (9) and vertical being connected of hot water line (10) of water heater, hot water line's (10) a end is connected with an end perpendicular quadrature of negative pressure line (13).The cavity that quadrature connects is shunting chamber (11), and the other end of negative pressure line (13) is connected with cylindrical steady flow section (4) perpendicular quadrature, and the quadrature junction constitutes negative pressure cavity (5).Hot water line's (10) the other end is hot water effluent's joint (12), and seal (14) also is housed on hot water effluent's joint (12).The end top of negative pressure line (13) is hot water plug (16).
When using the utility model, (with reference to Fig. 1, Fig. 2), water is by cold water water supply connector (1), shrink horn chamber (2) through taper shape, the flow velocity of water quickens gradually in this section, flow velocity reaches maximum during to cylindrical restriction (3), when water flows to cylindrical steady flow section (4) through cylindrical restriction (3), this moment, the flow velocity of water was to stablize flow at high speed, according to the working fluid conservation of energy in pipeline, at the varying-arca channel flowing liquid, somewhere when its flow velocity reaches certain value, the principle of negative value can appear in this place's pressure, so swiftly flowing liquid locates to present negative pressure state at negative pressure cavity (5).Water is in the process of divergent contour horn chamber (6), its speed is slowed down gradually, flow to cold water pipeline (7) when locating, the flow velocity of water is tending towards normal speed, this moment, water flow to water heater by the cold water pipe joint (8) that connects water heater again, the pipe joint of hot water (9) of water after the heat exchanger heats in water heater by connecing water heater, flow to shunting chamber (11) when locating, hot water is except flowing out for using through hot water line (10) and hot water effluent's joint (12), some hot water will be drawn in this chamber and the cold water mix of coming in by cold water water supply connector (1) by negative pressure line (13) by negative pressure cavity (5), hot and cold water through mixing passes through cylindrical steady flow section (4) again, conical diffusion horn chamber (6), cold water pipeline (7), the cold water pipe joint (8) that connects water heater carries out the secondary cycle heating when sending into heat exchanger in the water heater, heated hot water is sent for using except hot water effluent's joint (12), also have part hot water to be drawn into this chamber by negative pressure cavity (5) by negative pressure line (13) again and send into the water heater heating with cold water mix again, so continuous circulation, thereby reach under the constant situation of water heater capacity, improve the hot water temperature that hot water effluent's joint (12) flows out for use.
The utility model, the part hot water that is inhaled into negative pressure cavity (5) through actual measurement can reach 1.4 liters of per minutes, simultaneously for guaranteeing the negative pressure state of negative pressure cavity of the present utility model (5), except will design suitably to cylindrical restriction (3), also there is the relation that is complementary of loading in it with control valve in the former water heater during installation.
