Abstract
The utility model discloses a vertical enamel inner container for an electric heater, which comprises an enamel inner container whose upper portion is provided with an inlet and an outlet and electric heating pipes, and is characterized in that the enamel inner container comprises a main enamel inner container and one or more than one sub enamel inner container, the inlet of the main enamel inner container and the inlet of the sub enamel inner container are communicated through a water inlet connecting pipe, and the outlets are connected through a water outlet connecting pipe. The enamel inner container has the advantages of high degree of free assembly, simple technique, light volume, even cold and hot water mixing, and high hot water yield after adopting the structure that each enamel inner container with small diameter is independently designed, and is connected in parallel.
Description
Technical field
The utility model relates to a kind of electric heater inner bag, especially a kind of electric heater enamel inner container.
Background technology
From material, when using, existing inner container of electric water heater needs high temperature resistant and water-fast corrosion, and adopt stainless steel to make usually.Yet stainless steel costs an arm and a leg, and makes electric heater cost of manufacture height.For reducing the cost of manufacture of electric heater, the manufacturer selects for use price only to be the enamel of stainless steel 1/8th to 1/4th, but enamel material easily produces enamel defect in perforate or welding position.
On structure, present enamel inner container electricity electric heater on the market, inner bag is a columniform inner bag normally, change amount of capacity by the diameter that changes inner bag, when larger capacity, the inner bag diameter will be very big, is placed in the bathroom and will takies more space.
For dwindling the inner bag diameter, thereby dwindle the electric heater volume, other has a kind of enamel inner container to adopt two inner-tube structures, with two small diameter cylinder shape inner bag polyphones, middle several tube connectors that adopt connect (as Chinese patent 02267140.4) by being welded to connect, or with the centre circle of two minor diameter inner bags respectively flange weld.There is following shortcoming in this structure: operability is not good in welding procedure complexity, the production process; In the enamel process,, thereby use consequences such as causing the corrosion of carbon steel inner bag from now on because the out-of-flatness of tube connector place can cause defectives such as inhomogeneous, the scarce porcelain of enamel coating coating at the tube connector position; Need welded and installed between each enamel inner container, the combination free degree is not high.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of combination free degree height, technology is simple, volume is light and handy, hot and cold water mixes, and goes out the vertical enamel inner container of the high electric heater of hot water rate.
For achieving the above object, the utility model adopts following technical scheme:
The vertical enamel inner container of a kind of electric heater comprises: which is provided with enamel inner container, the electric heating tube of water inlet and delivery port, it is characterized in that: described enamel inner container comprises a main enamel inner container, and one or more secondary enamel inner container; The water inlet of main enamel inner container and secondary enamel inner container is communicated with by the water inlet tube connector; Its delivery port is communicated with by the water outlet tube connector.
The upper and lower end parts of described enamel inner container cylinder is provided with the flange that is welded in the cylinder body.
Described water inlet is arranged on the bottom of each enamel inner container cylinder, and delivery port is arranged on the upper end of each enamel inner container cylinder.
Between described water inlet tube connector and water inlet by being threaded; Between water outlet tube connector and delivery port by being threaded.
There is a water inlet pipe to be connected with the water inlet tube connector; Water inlet tube connector pipeline between described water inlet pipe and the secondary enamel inner container water inlet is provided with by-pass valve control.
Described enamel inner container cylinder bottom has sewage draining exit, and blow-off pipe and sewage draining exit are by being threaded.
There is an outlet pipe to be connected with the water outlet tube connector; Described outlet pipe causes the enamel inner container below from the enamel inner container top.
After adopting this technical scheme, the utlity model has following advantage:
Each enamel inner container is independent inner bag, is equipped with independently electric heating tube and temperature controller, can select for use different tube connectors that it is connected in parallel according to different water consumption needs, combination free degree height; By being threaded, reduce the inner bag weld seam between tube connector and the inner bag intake-outlet, technical process is simplified; Adopt independently cylinder type inner bag, realize best pressure-bearing effect; Hot and cold water between each inner bag mixes more even, because each inner bag is independently, can realize the raising of hot water delivery rate again, fully effectively utilizes hot water; Each inner bag all has independently heating and control device and by-pass valve control, can realize independent control, in summer or use the hot water amount when fewer, can only heat the water of main enamel inner container and the water of the secondary enamel inner container of part, thereby reach purpose of energy saving; The convenient inner bag that cleans of blow-off pipe is set.
