Abstract
A water heater electric heating body comprises a casing (21) and heating wires (6), wherein the casing (21) is provided with diversion pipes (22) communicated with each other, and the heating wires (6) are arranged in the diversion pipes (22). The utility model is characterized in that: the casing (21) is flat and is divided into a left area, a middle area and a right area (A, B, C), the heating wires (6) are arranged in the diversion pipes (22) in the middle area (B), and the diversion pipes (22) in the left area and right area (B, C) are water passages. The utility model adopts the flat casing of the electric heating body, thereby bringing about a smaller size of the electric heating body and a compacter structure of the internal diversion pipes. In addition, as the heating wires are only arranged in the up-run section of the water passage, air bubbles go up with the up-run section of the water passage instead of staying on the heating wires, thereby effectively preventing the heating wires from burning out due to air bubbles attached to the surfaces of the heating wires, and bringing about good safety performance and longer service life of the heating wires.
Description
Technical field
The utility model relates to a kind of electric heating body, particularly a kind of electric heating body that uses in water heater.
Background technology
Electric heating body is a critical piece in the water heater, the good serviceability that can directly have influence on water heater soon of electric heating body design.Existing calandria mostly is barrel shrond, and cavity is distributed in the barrel shrond can not make full use of the space, causes the water heater volume of the calandria that uses this kind structure bigger.As the patent No. is a kind of calandria the Chinese utility model " a kind of water heater electric heating body " of ZL01269267.0 (Granted publication number for CN2511089Y) has disclosed: it comprises a left side, right support, support is provided with several installing holes, many heating tube liquid sealings cooperations arranged side by side are installed in a left side, between the right support, a left side, the outer end of right support is provided with outer end cap, a left side, a right outer end cap and a left side, right support constitutes inner liquid sealing cavity with cavity, heating tube communicates with cavity, on a side outer end cap, be provided with water inlet, the opposite side outer end cap is provided with delivery port, the two ends installing electrodes sheet of outer surface of tube body.The heating tube of this calandria is set up in parallel, and the liquid sealing cavity body structure is compact inadequately, makes that whole calandria overall volume is bigger, therefore requires further improvement.
The utility model content
Technical problem to be solved in the utility model is a kind of compact conformation is provided at above-mentioned prior art present situation, rationally makes the water heater electric heating body that volume is littler.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this water heater electric heating body, include housing and heater strip, housing has the water conservancy diversion water pipe that is interconnected, heater strip is sent out and is put in the water conservancy diversion water pipe, it is characterized in that described housing is flat and is divided into three zones, left, center, right, described heater strip is arranged in the water conservancy diversion water pipe of central region, and the water conservancy diversion water pipe of left and right regions is a water-flowing path.
Be communicated with the back conduction with external circuit for making heater strip pass through this metal connection post, described heater strip is naked silk heating element heater, and two ends connects by two metal connection posts, also is with sealing ring on the described metal connection post, can prevent to leak.
Compared with prior art, advantage of the present utility model is to adopt the calandria of flat structural housing can make that the calandria volume is littler, structure between the inner water conservancy diversion water pipe is more compact, only be arranged in the up section water route owing to heater strip simultaneously, therefore the bubble that produces can up run together along with up section water route, thereby can not reside on the heater strip, can prevent effectively that the heater strip surface is because of adhering to the phenomenon that bubble causes heater strip to blow, security performance is good, thereby makes the longer service life of heater strip.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of the utility model embodiment.
Fig. 2 is the vertical view of the utility model embodiment.
Fig. 3 is the structure expanded view of Fig. 2.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, be water heater electric heating body of the present utility model, it includes loam cake 1, electric heating body 2 and lower cover 3, in order to guarantee the unimpeded and excellent sealing performance in whole water route, between described loam cake 1 and the electric heating body 2, be separated with water shutoff circle 4,5 respectively between electric heating body 2 and the lower cover 3.
Described water heater electric heating body 2 includes housing 21 and heater strip 6, as shown in Figure 2, has the water conservancy diversion water pipe 22 that is interconnected in the housing 21, heater strip 6 is arranged in the water conservancy diversion water pipe 22, described housing 21 is flat and is divided into left, center, right three regional A, B, C, heater strip 6 is arranged in the water conservancy diversion water pipe 22 of central region B, and the water conservancy diversion water pipe 22 of left and right regions A, C is a water-flowing path.
Have 20 water conservancy diversion water pipes 22 that are interconnected in the housing 21 at interval with obtaining after electric heating body 2 expansion, as shown in Figure 3, according to water inlet direction (In) shown in the figure and delivery port direction (Out), in odd number water conservancy diversion water pipe, form up section water route (using shown in the arrow " ↑ " among the figure), then form descending section water route (not indicating among the figure) in even number water conservancy diversion water pipe, heater strip 6 just is installed on and is arranged in the water conservancy diversion water pipe 22 of central region B at up section water route 21a, 21b, 21c, 21d; For ease of the dismounting of heater strip, described central region is at the water conservancy diversion water pipe in up section water route thick (seeing 7,9,11, the 13 water conservancy diversion water pipes that indicate among Fig. 2); In order to improve the thermal efficiency, described heater strip 6 is naked silk heating element heater, and two ends connects by two metal connection posts 7, for preventing to leak, also is with sealing ring 8 on metal connection post 7.
Side at heater strip 6 has the 22 direct water flowings of seven water conservancy diversion water pipes, the opposite side of heater strip 6 has the 22 direct water flowings of six water conservancy diversion water pipes, has so just formed two water resistances, makes that the leakage current in water inlet and the delivery port place water reduces greatly, to meet the limit that human body can bear, fool proof.
