Abstract
The utility model relates to a formula of preventing frostbite forced-ventilated formula gas heater, including casing, fan, controller and heat exchanger, wherein fan, controller and heat exchanger device are in the casing, and its characterized in that still includes built-in temperature sensor, outer temperature sensor, and in built-in temperature sensor device just the temperature sensing head stretched into the heat exchange tube on heat exchanger's heat exchange tube, outside the temperature sensor device just the temperature sensing head stretched out the casing on the casing, built-in temperature sensor, outer temperature sensor and fan were connected with the controller electricity respectively. The utility model discloses temperature is less than the uniform temperature in the heat exchanger heat exchange tube, and when ambient temperature is higher than the uniform temperature than the intraductal temperature of heat exchange, the controller just starts the fan and rotates, with indoor warm air suction heat exchanger heat transfer, with the intraductal surplus water heating of heat exchanger, later through the tub discharge chamber of discharging fume outdoor, it also blocks outdoor cold air and flows backward toward the pipe of discharging fume simultaneously to exhaust fume, consequently, the utility model discloses can not only effectively prevent forced-ventilated formula gas heater pipeline frost crack, the effect of preventing frostbite is showing, simple structure moreover, low in manufacturing cost is honest and clean.
Description
Technical field
The utility model belongs to a kind of forced-ventilated gas water heater of tool antifreeze function, belongs to the improvement technology of forced-ventilated gas water heater.
Background technology
At northern area, winter, cold was very long, and wind-force is generally bigger, and night, outdoor temperature was lower.As the saying goes---the hole of pinprick, the big wind that struggles against, northern area is indoor generally more airtight, and heating system is arranged, and indoor temperature generally has more than 10 ℃.Because it is outdoor that the smoke exhaust pipe of forced-ventilated gas water heater leads to, outdoor cold air gets in the heat exchanger through smoke exhaust pipe easily.Surplus water in the heat exchanger freezes when being lower than 0 ℃, causes the spalling of heat exchanger pipeline.
Existing technical scheme has usually: electrical heating antifreezing, small fire burner heating and anti-freezing, the draining of manual drainage valve.Electrical heating antifreezing is because of considering safety, and its structure causes the installation site away from the U type pipe that is prone to bursting by freezing, conducts heat slowly so cause, and is intrinsic also high with use cost; Small fire burner heating and anti-freezing complex structure is intrinsic also high with use cost; The manual drainage valve needs user manual operations draining valve to discharge water, and the user usually forgets and discharges water in actual the use, causes the bursting by freezing of forced-ventilated gas water heater machine inner conduit.
Summary of the invention
The purpose of the utility model is to provide a kind of forced-ventilated gas water heater with antifreeze function, and is not only simple in structure, and cheap for manufacturing cost, energy-conservation, and good effect of freezing protection prevents that effectively the forced-ventilated gas water heater pipeline is by bursting by freezing.
In order to achieve the above object; The technical scheme of the utility model is: a kind of anti-freeze type forced-ventilated gas water heater; Comprise housing, blower fan, controller and heat exchanger; Wherein blower fan, controller and heat exchanger device be in housing, it is characterized in that also comprising built-in temperature sensor, the outer temperature sensor of machine, the built-in temperature sensor device on the heat exchanger tube of heat exchanger and temperature-sensitive head put in the heat exchanger tube; The outer temp sensor device of machine on housing and temperature-sensitive head stretch out outside the housing, built-in temperature sensor, the outer temperature sensor of machine and blower fan are electrically connected with controller respectively.
Said built-in temperature sensor device on the U type pipe of the both sides of heat exchanger and temperature-sensitive head put in the U type pipe.
The outer temperature sensor of described built-in temperature sensor and machine is thermosensitive resistance type or sheet metal type.
The utility model is owing to be employed in inside and outside the housing structure that device respectively has the two temperatures sensor, and water temperature is lower than uniform temperature in the heat exchanger heat exchanger tube, and environment temperature is when water temperature is higher than uniform temperature in the heat exchanger tube; Controller just starts blower fan and rotates, with the heat exchange of indoor warm air suction heat exchanger, with surplus water heating in the heat exchanger tube; Outdoor through the smoke exhaust pipe discharge afterwards, air draft also stops that outdoor cold air pours in down a chimney toward smoke exhaust pipe simultaneously, therefore; The utility model can not only effectively prevent the bursting by freezing of forced-ventilated gas water heater pipeline; Antifreezing effect is remarkable, and simple in structure, and is cheap for manufacturing cost.
Description of drawings
Fig. 1 is the utility model anti-freeze type forced-ventilated gas water heater structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; A kind of anti-freeze type forced-ventilated gas water heater; Comprise housing 1, blower fan 3, controller 4, built-in temperature sensor 5, the outer temperature sensor 2 of machine and heat exchanger 6; Wherein blower fan 3, controller 4 and heat exchanger 6 devices are in housing 1; Built-in temperature sensor 5 installs on the heat exchanger tube of heat exchanger 6 and temperature-sensitive head puts in the heat exchanger tube, and the outer temperature sensor 2 of machine installs on housing and temperature-sensitive head stretches out outside the housing, and built-in temperature sensor 5, the outer temperature sensor 2 of machine and blower fan 3 are electrically connected with controller 4 respectively.
In the present embodiment, install for convenient, said built-in temperature sensor 5 installs on the both sides of heat exchanger 6 U type pipe 61 and temperature-sensitive head puts in the U type pipe.The outer temperature sensor 2 of described built-in temperature sensor 5 and machine is thermosensitive resistance type or sheet metal type.
The utility model operation principle is following: when outdoor temperature was low, controller 4 detected through built-in temperature sensor 5 when water temperature is lower than certain temperature in the both sides U type pipe of heat exchanger 6, in this instance is 4 ℃; And when detecting water heater installation environment temperature than the high certain temperature of water temperature in the U type pipe through the outer temperature sensor 2 of machine; In this instance be 3 ℃, controller 4 just starts blower fan 3 and rotates, and makes indoor warm air get into heat exchanger 6 heat exchange; Surplus water in reheat heat exchanger 6 pipes; Just outdoor through the smoke exhaust pipe discharge afterwards, in outdoor air draft, stopped that also outdoor cold air pours in down a chimney toward smoke exhaust pipe; Prevent surplus water freezing thereby play, play antifreeze effect.
When water temperature is higher than design temperature in controller 4 detects U type pipe, in this instance be 10 ℃, controller 4 is just controlled blower fan 3 and is shut down, and plays 3 effects of protection blower fan.
