Abstract
The utility model provides an electric water heater with plastic inner container, the water inlet and outlet on the plastic inner container and the water inlet and outlet pipe connected with the plastic inner container, the characteristics are that: the tail ends of the water inlet and the water outlet are respectively provided with an annular bulge, the connecting ends of the plastic water inlet and the plastic water outlet pipes and the water inlet and the water outlet are inner and outer layers of circular sleeves, the inner layer of circular sleeve extends into the corresponding water inlet and the corresponding water outlet, and the outer layer of circular sleeve is sleeved on the corresponding annular bulge of the water inlet and the corresponding annular bulge of the water outlet. The plastic water inlet pipe and the plastic water outlet pipe are respectively provided with 2 symmetrical grooves on the outer walls of the connecting ends of the plastic water inlet pipe and the plastic water outlet pipe and are respectively provided with an omega-shaped water pipe fixing clamp which respectively penetrates through the two grooves on the outer walls of the plastic water inlet pipe and the plastic water outlet pipe and is clamped behind the annular bulges of the plastic water inlet pipe and the plastic water outlet pipe, so that the plastic water inlet pipe and the plastic water outlet pipe are clamped on the water inlet pipe and the water outlet pipe of the plastic liner. The structure is reasonable, the water inlet and the water outlet are tightly connected with the water inlet pipe and the water outlet pipe, the sealing performance is good, and the use is safe and reliable.
Description
Technical field
The utility model is the improvement about inner container of electric water heater water inlet pipe and water outlet pipe mounting structure, particularly a kind of plastics inner bag electric heater.
Background technology
Have the plastics intake-outlet on the existing electric heater plastics inner bag, generally, entery and delivery port has outer silk, be connected with it with the plastics inlet tube and outlet tube that has internal thread and since this structure be plastics with working of plastics between be threaded, bear the ability of hydraulic pressure, and because the plastic whorl abrasion-resistance is poor, when repeatedly dismounting connected, it was serious thread abrasion to occur, seals bad situation.
At the be connected problem that exist of plastics intake-outlet with plastic pipe, a kind of improved technology is arranged, be provided with the plastics intake-outlet on the plastics inner bag, entery and delivery port has outer silk, and what be connected with entery and delivery port is the metal water inlet pipe and water outlet pipe that has internal thread, this structure, by being threaded, during installation, closely cooperate between plastics entery and delivery port and the metal inlet tube and outlet tube if firmly tighten, make the distortion of plastics entery and delivery port easily, even it is broken that entery and delivery port is squeezed.Simultaneously, because inlet tube and outlet tube is a metal tube, if electric heater generation leaky, leakage current can be derived along metal tube, and the user will cause danger.
Summary of the invention
The purpose of this utility model is for overcoming the shortcoming and defect that prior art exists, and a kind of plastics inner bag electric heater is provided, and it is rational in infrastructure, and plastics inner bag entery and delivery port closely is connected with inlet tube and outlet tube, and good airproof performance is safe and reliable.
The purpose of this utility model is achieved by the following technical solution: a kind of plastics inner bag electric heater, comprise entery and delivery port and connected inlet tube and outlet tube on plastics inner bag, the inner bag, it is characterized in that: the end of described entery and delivery port respectively has an annular projection, the link of plastics inlet tube and outlet tube and entery and delivery port is inside and outside two-layer circular casing, inner layer sleeve stretches in the corresponding entery and delivery port, and outer layer sleeve is enclosed within on the corresponding entery and delivery port annular projection.
Respectively be provided with the groove of 2 symmetries on the link outer wall of described plastics inlet tube and outlet tube and entery and delivery port, for respectively disposing one " Ω " shape water pipe geometrical clamp, passes two grooves from plastics inlet tube and outlet tube outer wall respectively the plastics inlet tube and outlet tube, and be stuck in the annular projection back of plastics inner bag entery and delivery port, the plastics inlet tube and outlet tube is clipped on the plastics inner bag entery and delivery port.
The annular projection of described plastics inner bag entery and delivery port is a truncated cone, forms the space corresponding with the truncated cone annular projection between the inside and outside two-layer circular casing of plastics inlet tube and outlet tube.
The sealing ring that is provided with in the described water-in and water-out sleeve pipe embeds in the endless groove at place, entery and delivery port inwall outer.
The end of described plastics inlet tube and outlet tube connects one respectively and has outer wire head.
The utility model compared with prior art has many advantages and good effect:
The entery and delivery port of the utility model plastics inner bag has the annular projection structure, the link of plastics inlet tube and outlet tube and entery and delivery port is inside and outside two-layer circular casing, inner layer sleeve stretches in the corresponding entery and delivery port, outer layer sleeve is enclosed within on the corresponding entery and delivery port annular projection, and by the clamping of " Ω " shape water pipe geometrical clamp, working of plastics and metal tube have been overcome by being threaded, make the distortion of plastics intake-outlet when firmly tightening easily, even make intake-outlet squeeze broken shortcoming, and, simple in structure, easy for installation.Because of what cooperate installation with the plastics entery and delivery port is the plastics inlet tube and outlet tubes, so integral insulation is effective, safe and reliable.
Description of drawings
Fig. 1 is the plastics inner bag part section structure chart that the utility model electric heater intake-outlet has annular projection;
Fig. 2 is the part section structure chart that the utility model electric heater plastics inner bag intake-outlet is connected with the plastics inlet tube and outlet tube;
Fig. 3 is the front view that the utility model electric heater is installed " Ω " shape water pipe geometrical clamp that the plastics inlet tube and outlet tube disposed.
The specific embodiment
As shown in Figure 1-Figure 3, embodiment for the utility model plastics inner bag electric heater, at the end of the entery and delivery port 2 of plastics inner bag 1 annular projection 3 that is shaped as truncated cone is set respectively, one end of plastics inlet tube and outlet tube 4 is the wire head that has outer silk, plastics inlet tube and outlet tube 4 is inside and outside two-layer circular casing with the link of entery and delivery port 2, forms the space corresponding with truncated cone annular projection 3 between the inside and outside two-layer circular casing.Inner layer sleeve stretches in the corresponding entery and delivery port 2, and outer layer sleeve is enclosed within on the annular projection 3 of corresponding entery and delivery port.
On the link outer wall of plastics inlet tube and outlet tube 4 and entery and delivery port 2, respectively be provided with the groove 5 of 2 symmetries, pass two grooves 5 from plastics inlet tube and outlet tube 4 outer walls respectively respectively disposing one " Ω " shape water pipe geometrical clamp for plastics inlet tube and outlet tube 4, and be stuck in annular projection 3 back of plastics inner bag entery and delivery port 2, plastics inlet tube and outlet tube 4 is clamped in respectively on the entery and delivery port 2 of plastics inner bag 1.The sealing ring 6 that is provided with in plastics water-in and water-out sleeve pipe 4 embeds in the endless groove at place, entery and delivery port 2 inwall outers good sealing effect.
