Abstract
The utility model provides an electric heater including the box, is equipped with in the box and overflows the inner bag, has electric heating pipe and a drainage tube overflowing the inner bag inside seal, the protective case that electric heating pipe formed including 825 stainless steel manufacturings of adoption in the box still respectively the volume of being equipped with the control flow flow switch, control water heating temperature automatic temperature detect switch and high temperature protection switch. The present case provides the electric heater that a heat transmission effect is good, durable, be difficult for the scale deposit.
Description
[technical field]
The utility model relates to a kind of swimming pool equipment, particularly relates to a kind of electric heater.
[background technology]
In the market for heating, electric heating tube protective casing mostly adopts common stainless steel material, anti-Rotten poor performance, and do not spray Teflon technique, the easy fouling of electric heating tube, causes electric heating tube heat radiationBad, electric heating tube easily burns out. In addition, the electric heater on market not simultaneously design discharge switch orAutomatic temperature control switch, high temperature protection switch, the frequent fault of electric heating tube, electric heater is very short service life.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of heat-transfer effect good, durable,Less scaling electric heater.
For solving the problems of the technologies described above, the utility model has adopted following technical proposals:
A kind of electric heater, is characterized in that including casing 1, is provided with overcurrent inner bag 2 in casing 1,In overcurrent inner bag 2, be sealed with electric heating tube 3 and drainage tube 4, described electric heating tube 3 includes and adopts 825 notThe protective casing that rust steel making forms.
Electric heater as above, is characterized in that being also respectively equipped with control discharge in described casing 1Flow switch 5, control heating water temperature automatic temperature control switch 6 and high temperature protection switch 7.
Electric heater as above, is characterized in that being provided with Teflon protective layer in protective casing outside.
Electric heater as above, is characterized in that being provided with middle plate 8 in casing 1, on middle plate 8, is provided withBinding post 9, breaker 10, A.C. contactor 11, described flow switch 5 is located on middle plate 8.
Electric heater as above, is characterized in that establishing between described overcurrent inner bag 2 and the bottom of casing 1There is bar shaped seam.
Compared with prior art, the beneficial effects of the utility model are:
The electric heating tube protective casing of one, this case adopts the splendid stainless steel of 825 antiseptic properties first, thoroughlySolve the Anticorrosion of electric heating tube protective sleeve.
Two, electric heating tube protective casing outside adopts spraying Teflon technique first, thoroughly solves electric heating tubeScale problems.
Three, electric heater flow switch, automatic temperature control switch, high temperature protection switch triple protection simultaneously, reallyProtect electrical heating and move in the situation that having water flow, electric heating tube temperature lower, in the time there is high temperature from dynamic circuit breakerOpen, solve electric heater and occur that abnormal high temperature burns out the problem of electric heating tube.
[brief description of the drawings]
Fig. 1 is exploded view of the present utility model;
Fig. 2 is exploded view of the present utility model.
[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawingAnd embodiment is described further the utility model. Should be appreciated that specific embodiment described hereinOnly in order to explain the utility model, and be not used in restriction the utility model.
A kind of electric heater, includes casing 1, is provided with overcurrent inner bag 2, at overcurrent inner bag 2 in casing 1Inside be sealed with electric heating tube 3 and drainage tube 4, described electric heating tube 3 include adopt 825 stainless steel manufactures andThe protective casing becoming. 825 stainless antiseptic properties are splendid, and it is 825 stainless that the chemical substance in water can not corrodedSteel, therefore electric heating tube protective casing can not be corroded, puncture, electric heating tube failure rate is low.
The automatic of water temperature heated in the flow switch 5, the control that in described casing 1, are also respectively equipped with control dischargeTemperature detect switch (TDS) 6 and high temperature protection switch 7.
Be provided with Teflon protective layer in protective casing outside. Make protective casing outside never fouling layer of scale leadHot property is poor, and thermal conductivity is good, and electric heating tube internal-external temperature difference is minimum, and inner electrical heating wire temperature is lower, electricityHeater strip cold operation for a long time, electrical heating wire fault rate is extremely low.
In casing 1, be provided with middle plate 8, on middle plate 8, be provided with binding post 9, breaker 10, ac contactorDevice 11, described flow switch 5 is located on middle plate 8. In the protection of electric heater design automatic temperature control switch, whenTemperature is closed higher than setting value just action lower than setting value and temperature, confirms protection electric heating tube normal heating.The high temperature protection switch arranging automatically disconnects in the time there is high temperature, and manual reset, avoids high temperature to burn out electricityHeating tube, guarantees electric heater electrical safety. In addition the water flow switch arranging, guarantees that electrical heating is not having waterOut of service when the abnormal conditions such as mobile or discharge is less than normal. Only there iing flow to reach the situation of designing requirementThe lower flow switch action closure that just can make, electric heater work, guarantees that electric heating tube can be in the lower work of temperatureUnder condition, move. Further, independently drainage tube of electric heater overcurrent inner bag indoor design, water must pass through completelyThe electrothermal tube drainage tube of just flowing through, then flow to electric heater delivery port, guarantee that electric heater inner container temperature is even,Electrical heating wire is long-term to be moved under low-temperature condition uniformly, extends electrothermal tube service life.
Between overcurrent inner bag and the bottom of casing, be provided with bar shaped seam, this bar shaped seam is 2mm bar shaped seam, like thisBoth be conducive to heat radiation, be conducive to again bottom hydrophobic, prevented the toys such as bulky grain thing or cockroach, mouse simultaneouslyEnter electric heater casing, damage electric heater inner member.
Should be understood that, for those of ordinary skills, can be improved according to the above descriptionOr conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
