Abstract
The utility model discloses an electrical heating system for hot air, which comprises a temperature sensor for measuring air temperature, a temperature controller and a main heating group used for heating air, wherein the temperature sensor is connected with the temperature controller which is connected with the main heating group. The electrical heating system further comprises a group of auxiliary heating groups, the auxiliary heating groups are connected with the temperature controller, and a time relay is arranged between the main heating group and the auxiliary heating groups. Compared with the prior art, two independent heating groups are arranged, and the two heating groups are matched in starting under the control of the temperature controller and the time relay, thereby controlling temperature accurately, and ensuring that the heated air has smaller temperature difference within the range of plus and minus 2 degrees.
Description
Technical field the utility model relates to a kind of heating system, especially a kind of electric heating system of hot-air.
In the background technology prior art, the electric heating system of hot-air generally is made up of the temperature sensor of detected temperatures, temperature controller and one group of heating tube of being responsible for controlling, during use, by technological requirement a value (as 60 ℃) is set, and can normally use.The greatest problem of this heating system is: when arriving limiting temperature and begin to add hot-air, because the heating tube heating efficiency is limited, atmosphere temperature rising is slower, causes air themperature can not rise at once, may still can be lower than design temperature or swings near design temperature.When using powerful heating tube, though heating tube quits work, there is waste heat in temperature after arriving design temperature, can cause the continuation of temperature to be risen again.Will cause the temperature difference of temperature that electric heating system regulates and design temperature bigger like this, can reach ± 5 ℃.This temperature difference has certain influence to the quality of product.
Summary of the invention problem to be solved in the utility model provides a kind ofly can control air themperature accurately, makes the air themperature that heated and the electric heating system of the hot-air that has a narrow range of temperature between the design temperature.
For addressing the above problem, the utility model comprises temperature sensor, the temperature controller of measuring air themperature and is used to add the main heating group of hot-air, described temperature sensor links to each other with temperature controller, temperature controller links to each other with main heating group, the electric heating system of this hot-air also comprises one group of secondary heating group, this pair heating group links to each other with temperature controller, is provided with the time relay between major-minor heating group.
Owing to an original high-power heating tube has been splitted into two groups of relatively independent main heating groups and secondary heating group, has been connected by the time relay between the major and minor heating group.Therefore, when temperature was lower than setting value, two groups of heating groups successively started, and in time for system provides enough heating powers, thereby made the air themperature fast rise.When temperature is about to be higher than setting value, one group of heating group is closed earlier, only there is one group of heating group to continue heating, thereby reduce the speed that air themperature raises fast, the temperature stabilization that makes hot-air has also been avoided too high surplus temperature and is made air themperature continue to rise and surpass the shortcoming of setting value in the scope of setting value.
Temperature controller of the present utility model stores two temperature values at least, comprises temperature upper limit, lowest temperature.
Owing to set temperature upper limit and lowest temperature, temperature controller can calculate suitable medium temperature like this, and this medium temperature is preferably the desired air themperature of keeping of user.Temperature controller is controlled the electric heater unit work of hot-air according to the temperature bound of setting and the medium temperature of calculating.The air themperature that detects when temperature sensor is a lower limit or following, and main heating group starts, and starts secondary heating group behind the time relay control certain hour; When air themperature that temperature sensor detects be medium temperature or more than, secondary heating group quits work, main heating group works on; The air themperature that detects when temperature sensor is the upper limit or when above, main heating group also quits work.Because the temperature bound that temperature controller can be set according to the user, effectively control the startup of major-minor heating group and close, thereby the air of the electric heater unit of this hot-air that makes has a narrow range of temperature.
The time relay of the present utility model can be adjustable.Owing to can control the startup blanking time of major-minor heating group by regulating the time relay, thereby make this hot air device to do suitable adjustment according to the temperature and humidity of air before the heating under the different condition.
Be respectively equipped with breaker on main heating group of the present utility model and the secondary heating group.This breaker can protection system open circuit under the operation irregularity situation immediately, has avoided further damage.
As 60 ± 2 ℃ of technological requirements, then can will be limited to 61 ℃ on the temperature controller, be limited to 59.5 ℃ down, it is 60.5 ℃ that temperature controller calculates medium temperature.The delay opening time of setting-up time relay is 10 seconds in addition.When just beginning to heat, temperature is lower than technological requirement value (60 ℃), and main heating group is at first started working, and according to setting, secondary heating group was started working after 10 seconds; When hot air temperature is raised to 60.5 ℃, secondary heating group at first stops heating, and main heating group works on; When hot air temperature was raised to 61 ℃, main heating group also stopped heating; When hot air temperature dropped to 59.5 ℃, main heating group was started working, and after 10 seconds, can not reach 60.5 ℃ as hot-air, and then secondary heating group begins heating, and hot-air quits work once reaching 60.5 ℃ of secondary heating groups.The whole control system is just carried out work by the various parameters of above setting.
In sum, the utility model compared with prior art, by using two groups of relatively independent heating groups, and these two groups of heating groups are the startups that cooperatively interact under the control of the temperature controller and the time relay, thereby control temperature accurately, make the heated air temperature difference reduce, change in ± 2 ℃ of scopes.
Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments:
Fig. 1 is a connection diagram of the present utility model.
