Description

A kind of Instant heating type two cup heaters

Technical field

The present invention relates to a kind of calandria, relate in particular to a kind of two cup calandria, be mainly used in the hot-water heating system of civilian or commercial Application.

Background technology

What instant electric water heater's calandria adopted in present market is single glass of mode of heating; This calandria only is suitable in water consumption is less or inflow temperature the is higher environment; As about 4L/min, can satisfy individual's bathing requirement in spring, summer, autumn water consumption; But winter discharge generally can only be below 3L/min, when discharge is that to measure be 5 ℃, the leaving water temperature maximum can only reach 38 ℃ when power was 8kW, particularly in northern China for 3L/min, entry; Have to go into coolant-temperature gage lower, such water yield is difficult to keep people's bathing.

Summary of the invention

Invented a kind of new heater in order to break my company of this limitation---a kind of Instant heating type two cup heaters; The maximum innovative point of this calandria is that it has two in-line Heating Cups; These two Heating Cups are that series system heats cold water, even go into coolant-temperature gage when being 5 ℃ in winter like this, leaving water temperature also can reach 44 ℃ when discharge was 9L/min; People's bathing temperature generally about 42 ℃, can satisfy a plurality of people bathing simultaneously requirement like this.

Technical scheme of the present invention to achieve these goals is to adopt following means to realize: a kind of Instant heating type two cup heaters; Form by water inlet pipe, outlet pipe, elementary heating chamber, secondary heating chamber, housing; Described water inlet pipe is connected elementary heating chamber lower curtate; Described elementary heating chamber and secondary heating chamber are installed in the housing; Described elementary heating chamber is connected through secondary water inlet pipe with secondary heating chamber, and said elementary heating chamber is parallel with secondary heating chamber draws close arrangement, and inside is respectively arranged with many heating tubes.

Described housing is provided with ground connection fixture, temperature controller and four housing fixtures, on the described housing, elementary heating chamber and secondary heating chamber top be respectively arranged with the temperature sensor sensing point.

Described water inlet pipe is provided with fixed screw and water flow sensing unit.

Described heating tube comprises heater strip, magnesia insulating barrier, red copper heat-conducting layer, and described heater strip is at the heating tube center, and described red copper heat-conducting layer is at outermost layer.

The present invention has following remarkable advantages and beneficial effect:

1) guarantees when inflow is enough big, still can provide the hot water of q.s, can supply many people to use simultaneously;

2) marshalling, rational in infrastructure attractive in appearance;

3) security performance is high;

4) little, the long service life of volume.

Wherein: the 1-outlet pipe; 2-level water inlet pipe; The 3-housing; 4-level heating chamber; The elementary heating chamber of 5-; The 6-heating tube; 7-housing fixture; 8-ground connection fixture; The 9-water inlet pipe; 10-temperature sensor sensing point; The 11-water flow sensing unit; The 12-temperature controller; The 13-heater strip; 14-magnesia insulating barrier; 15-red copper heat-conducting layer; The 16-fixed screw.

The specific embodiment

Shown in Fig. 1-3: a kind of Instant heating type two cup heaters; Form by outlet pipe 1, water inlet pipe 9, secondary heating chamber 4, elementary heating chamber 5, housing 3; Described outlet pipe 1 is connected secondary heating chamber 4 tops; Described secondary heating chamber 4 is installed in the housing 3 with elementary heating chamber 5; Described secondary heating chamber 4 is connected through secondary water inlet pipe 2 with elementary heating chamber 5, and said secondary heating chamber 4 and elementary heating chamber 5 are parallel draws close arrangement, and inside is respectively arranged with many heating tubes 6; Described housing 3 is provided with ground connection fixture 8, temperature controller 12 and four housing fixtures 7; Described housing 3 upper ends, secondary heating chamber 4 and elementary heating chamber 5 tops are respectively arranged with temperature sensor sensing point 10, and described water inlet pipe 9 is provided with fixed screw 16 and water flow sensing unit 11, and fixed screw 16 is connected water flow sensing unit 11 on the water inlet pipe 9.

As shown in Figure 4, described heating tube 6 comprises heater strip 13, magnesia insulating barrier 14, red copper heat-conducting layer 15, and described heater strip 12 is at heating tube 6 centers, and described red copper heat-conducting layer 15 is at outermost layer.

The present invention implements like this, and housing fixture 7 is fixed on whole device in the housing of water heater, and current get into elementary heating chamber 5 through water inlet pipe 9; Through heating tube 6 heating for the first time, the water of heating flows in the secondary heating chamber 4 through secondary water inlet pipe 2 in elementary heating chamber 5, and the water of 6 pairs of heating for the first time of heating tube that secondary heating chamber 4 is inner are through heating once more; Flow into outlet pipe 1 then, the temperature controller 12 on its middle shell 3 is connected with temperature sensor sensing point 10, and the temperature of 10 pairs of water of temperature sensor sensing point is monitored; Guarantee temperature below 95 degrees centigrade, when the temperature of water was higher than 95 ℃, temperature controller 12 can send the signal that stops to heat; Avoid the phenomenon of dry combustion method to take place; Water flow sensing unit 11 can be monitored water inlet, and ground connection fixture 8 is used for fixing earth connection simultaneously, plays the electrocution-proof protection effect.

What should explain at last is: above embodiment only in order to the explanation the present invention and and unrestricted technical scheme described in the invention; Therefore, although this specification has carried out detailed explanation to the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of invention, and it all should be encompassed in the middle of the claim scope of the present invention.
