Abstract

The utility model discloses a novel solar water heater capable of being cleaned without disassembly. The water heater has a plurality of vacuum tubes. The diameters of the upper and the lower openings of each vacuum tube are the same. The upper end of each vacuum tube fixedly communicates with a cylindrical insulating water tank. The lower end of each vacuum tube fixedly communicates with a cuboid insulating tube-supporting water tank which has a stainless steel inner core and a polyurethane insulating coating. An insulating water tank drainage port and an insulating tube-supporting water tank drainage port are arranged at the homolateral lowest water level of the inner core of the insulating water tank and the insulating tube-supporting water tank respectively. The impurities (such as iron rust and sand) deposited inside the vacuum tube and the insulating water tank are easy to clean without disassembling the vacuum tube under the condition of keeping the original work efficiency of the household integrated solar water heater. The novel solar water heater facilitates the cleaning and decontamination, supplies clean and sanitary water to the users, and keeps the normal heat efficiency of the vacuum tube.

Description

Exempt to tear open blowdown cleaning solar water heater

Technical field

The utility model relates to a kind of device that utilizes solar energy to convert heat energy to, especially a kind ofly exempts to tear open blowdown cleaning solar water heater.

Background technology

The present integrated domestic solar water heater on the market, its structure comprises: the vacuum tube of attemperater, upper shed lower seal, support and only play the fixedly conduit saddle of vacuum tube effect.The shortcoming of this solar water heater is: though advance the magnetic valve that screen pack is installed on the cold water pipe, but because quality problem, can't filter impurity such as trickle rust grain, mud dirt, will be deposited in vacuum tube and the attemperater after a period of time, cause dirt easily, not only influence the endothermic effect of vacuum tube, and the water quality in the attemperater is as too dirty, in the time of can causing the user to have a shower, eyes are suffered from diseases such as conjunctivitis easily.Vacuum tube on the solar water heater all is upward insertion attemperaters, its structure is upper shed, sealing down, very easily cause the sewage row of pipe the inside not fall, after each blowdown is cleaned and is all wanted the professional that vacuum tube is split out one by one, just can dispose of sewage and clean up, not only the process workload is big, and has the easily impaired risk of vacuum tube.

The utility model content

What the purpose of this utility model provided a kind of simple and reasonable, easy blowdown cleaning exempts to tear open solar water heater, and not only blowdown is cleaned conveniently, can guarantee user's water sanitation and hygiene for a long time, and can keep the normal heat efficient of vacuum tube.

For solving the problems of the technologies described above, the technical solution of the utility model is:

The upper end of many upper and lower opening equal diameters vacuum tubes of solar water heater and columned attemperater are fixing to be communicated with, the lower end of vacuum tube and in be provided with stainless steel inner container, be provided with fixing connection of rectangular-shaped insulating pipe bracket water tank of polyamine fat heat-insulation layer outward; The same direction lowest water level of the inner bag of attemperater and insulating pipe bracket water tank place is provided with attemperater sewage draining exit, insulating pipe bracket water tank sewage draining exit respectively.

Attemperater and insulating pipe bracket water tank and vacuum tube opening are provided with the leakproof seal circle in the circular hole one to one.

The beneficial effects of the utility model:

Exempt to tear open blowdown cleaning solar water heater and do not changing under the work effect of integrated domestic solar water heater, need not remove impurity such as iron rust that vacuum tube just can blowdown cleans vacuum tube and attemperater the inside precipitation, mud dirt.Not only blowdown is cleaned conveniently, can guarantee user's water sanitation and hygiene for a long time, and can keep the normal heat efficient of vacuum tube.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is a stereogram of the present utility model.

The specific embodiment

According to shown in Figure 1, solar water heater mainly comprises: attemperater 1, support 2, vacuum tube 3, insulating pipe bracket water tank 4, attemperater sewage draining exit 5, insulating pipe bracket water tank sewage draining exit 6, equal tee 7, Blowoff ball valve 8, sewage pipe 9, exhaust cap 10, cold water inlet 11, hot water inlet 12.

Traditional solar energy vacuum tube is upper shed, the following structure of sealing, and existing design changes the lower end of traditional vacuum duct occlusion into the upper end same diameter round opening, and makes underlined line in the distance lower end mouth of pipe 5 centimeters.Traditional vacuum conduit saddle is changed into the insulating pipe bracket water tank 4 of rectangular shape, its internal layer is 304 stainless steel inner containers, skin is a polyamine fat heat-insulation layer, and middle same horizontal level is provided with and attemperater 1 corresponding opening circular hole directly over it, is provided with the leakproof cushion rubber in the hole.Attemperater 1 and insulating pipe bracket water tank 4 be tooth sewage draining exit 5, sewage draining exit 6 outside inner bag homonymy lowest water level place is provided with respectively all.

Attemperater 1 is installed on the support 2, the round perforate of the attemperater 1 on top and the insulating pipe bracket water tank 4 of bottom is alignd one by one, upper and lower opening and have specifically labelled vacuum tube 3 and insert support 2 top attemperaters 1 earlier and be provided with in the round perforate of leakproof seal circle, insert downwards again in the corresponding round perforate that is provided with the leakproof seal circle of support 2 lower end insulating pipe bracket water tanks 4, the leakproof seal circle of insulating pipe bracket water tank 4 and the alignment of the telltale mark of vacuum tube 3, avoid the bottom of vacuum tube 3 to push up the inwall of insulating pipe bracket water tank 4 and influence blowdown, mountedly exempt to tear open blowdown and clean the bottom of the every vacuum tube 3 of new type solar energy and will lead to mutually together, the sewage of all vacuum tube 3 the insides will pass through insulating pipe bracket sewage draining exit 6 like this, Blowoff ball valve 8 has been arranged.

With sewage pipe 9 attemperater sewage draining exit 5, insulating pipe bracket water tank sewage draining exit 6, threeway 7 and Blowoff ball valve 8 are coupled together, when blowdown is cleaned, for using water wisely, in the time of can selecting the attemperater low water level, close into cold water water valve then, open Blowoff ball valve, the sewage of attemperater 1 and vacuum tube 3 the insides will be discharged by attemperater sewage draining exit 5 and insulating pipe bracket water tank sewage draining exit 6, restart into cold water water valve flushing after having arranged, the water of discharging as sewage pipe 9 totally gets final product fully.

Oversize service time as solar water heater, the inwall incrustation scale water of vacuum tube 3 can't clean, and closes attemperater 1 earlier and advances the cold water water valve and go out the hot water water valve, opens Blowoff ball valve 8 and has arranged water, closes Blowoff ball valve 8 again.With the harmless weak acid solution of vinegar preparation, inject in the attemperater 1 from cold water inlet 11, calculate required capacity, every vacuum tube 3 is all filled with.After 20～30 minutes, open Blowoff ball valve 8 solution after the dissolving incrustation scales again and arranged, restart into the cold water water valve and rinse well and get final product.

Be installed in the solar water heater of pitched roof, also can replace Blowoff ball valve 8 with the control of 12 volts of no pressure electromagnetic valve apolegamy computer instrument.
