Abstract
The utility model discloses a device for controlling constant-temperature water discharge of a gas water heater. The device comprises a temperature control device, wherein the temperature control device is electrically connected with a temperature detector, and the temperature detector can detect the water temperature and can send the detected water temperature in the form of an electrical signal to the temperature control device; the temperature control device is also electrically connected with a water flow detector, and the water flow detector can detect the water flow in a water pipe and can send the detected water flow in the form of an electrical signal to the temperature control device; and the temperature control device can automatically calculate the fire power value according to the current water temperature, the current water flow and the preset water temperature and send the fire power value in the form of an electrical signal to a combustion device and can control the fire power of the combustion device. The control device can re-adjust the fire power value when the real-time water temperature is close to the preset water temperature, so as to achieve the effects of accurately stabilizing the temperature, shortening the temperature-stabilizing time and reducing the excessive temperature difference between cold water and hot water.
Description
Technical field
The utility model relates to a kind of constant-temperature effluent control device of constant temp gas water heater, relates in particular to a kind of constant temp gas water heater effluent control device that only uses a temperature detector.
Background technology
Present most gas water heater in use, it is cold water that a very long time is arranged when often just having started shooting, and emits a period of time when going out hot water when cold water, can occur the too high situation of hot water temperature again, and the too drastic situation of hot and cold water temperature is appearred in the bather.The reason that produces above-mentioned situation mainly contains two kinds: the one, and be cold water at the gas heater water tank to the water in the delivery port, this part is inevitable; The 2nd, because the gas heater design is caused.Common gas heater only is provided with temperature detector in the delivery port position.When start work; Gas heater is earlier with fixing firepower work a period of time; Detect coolant-temperature gage by temperature detector in the time of the water tank water outlet, and judge the leaving water temperature that this is measured and the temperature difference of set water temperature, regulate the firepower of water heater then so that its water temperature reaches constant temperature.If set firepower when regulating greater than its fixing firepower, can cause that then temperature is lower than setting value, promote firepower through feedback then, cause out hot water too slow; If set firepower when regulating less than its fixing firepower, can cause that then temperature is higher than setting value, thereby cause the too drastic sense of discomfort of hot and cold water temperature.
The utility model content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of gas heater constant-temperature effluent control device, and this device can shorten the constant temperature time between the hot and cold water greatly, reduces the too drastic temperature between the hot and cold water, promotes the bath comfort degree.
The technical scheme that the utility model adopts in order to solve the problems of the technologies described above is:
A kind of gas heater constant-temperature effluent control device; Comprise water tank, be installed on the water outlet of water tank place temperature detector, be installed on discharge detector and water heater burner on the water tank water pipe; Also comprise temperature control device; Said temperature detector is electrically connected with said temperature control device, and said temperature detector can detect water temperature and can detected water temperature be sent to said temperature control device with the form of the signal of telecommunication;
Said discharge detector is electrically connected with said temperature control device, and said discharge detector can detect discharge in the water pipe and can detected discharge be sent to said temperature control device with the form of the signal of telecommunication;
Said temperature control device can calculate the firepower value automatically according to the detected current water temperature of temperature detector, the detected current discharge of discharge detector and set water temperature, and can this firepower value sent to said burner with electrical signal form and control the firepower size of said burner.
Said temperature control device is provided with control panel, and said set water temperature is set by said control panel, and this control panel can send to said temperature control device with electrical signal form with required water temperature.
The useful technique effect of the utility model is: this control device through temperature control device to the measured real-time discharge of the measured real-time water temperature of temperature detector, discharge detector and the COMPREHENSIVE CALCULATING of set water temperature; The required firepower value of burner heats when drawing start; And reach with set water temperature when close in real-time water temperature; Finely tune the firepower value once more, to reach accurate constant temperature, shorten constant temperature time and to reduce the effect of too drastic temperature between the hot and cold water.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: the 1-water tank; The 2-temperature detector; 3-discharge detector; The 4-burner; The 5-temperature control device.
The specific embodiment
In conjunction with Fig. 1 the utility model is done further detailed description.
When said gas heater has just been started shooting; Temperature detector 2 detects the water temperature at delivery port place; Because the water temperature at delivery port place is the water temperature of residual water in the machine during start just; This water temperature is near environment temperature, and is very approaching with actual inflow temperature, so with the inflow temperature of this water temperature value as gas heater.Program in the said temperature control device 5 is with inflow temperature, needed set temperature value and use detected first discharge of discharge detector 3 (can install with gas heater water inlet pipe or outlet pipe on) to calculate the required first firepower value automatically, and this first firepower value is sent to said burner 4.
The burner 4 of gas heater igniting back is with the work of the first firepower value then, and water temperature is heated near the set temperature value, and then this moment, delivery port place water temperature was a leaving water temperature, and leaving water temperature is near set temperature value.
The temperature detector 2 at said delivery port place feeds back to temperature control device 5 with measured leaving water temperature with the form of the signal of telecommunication; Temperature control device 5 calculates the required second firepower value automatically according to said leaving water temperature, set temperature value and use discharge detector 3 detected current second discharges, realizes that secondary fine setting firepower is to reach the purpose of accurate constant temperature.This process can shorten constant temperature time greatly, reduces the too drastic temperature between the hot and cold water, has promoted the comfortableness of bathing.
