Abstract
The utility model provides an electricity wall of an electric water heater. The electricity wall is smaller and can keep safe voltage when water keeps contact with human body. The electricity wall comprises a water pressure reducing body (1), connectors (2) sealed on both ends of the water pressure reducing body (1), and pipe joints (3) connected with the connectors (2) through screw threads, wherein the pipe joints (3) are used for connecting water inlet pipes or water outlet pipes; a circulating pipe (11) is arranged in the water pressure reducing body (1); the circulating pipe (11) consists of a plurality of stacked pipe cavities in series connection through plugs; and two openings at both ends of the circulating pipe (11) are communicated with the connectors (2). The above configuration can ensure smaller size of the voltage reducing body while ensuring long water channel, thereby meeting the anti-electric shock requirement of small instant electric water heater.
Description
Technical field
The utility model relates to the electric heater accessory, is specially electric water heater electricity-preventing wall.
Background technology
The most frequently used anticreep mode of existing electric heater mainly contains two kinds, and a kind of is to adopt leakage switch, when leakage current surpasses setting, can cut off the electricity supply automatically, guarantees that electric heater is safe and reliable.Another is that the electric leakage automatic detection device is installed on electric heater, when leakage current surpasses set quota, promptly reports to the police automatically, reminds the user to turn off power supply, to guarantee end user's life security.But above these two kinds are protected mode, all make the user stronger to the earth leakage protective device dependence, just in case electric switch or automatically the detection alarm device damage or leak electricity when malfunctioning, will take place, even threaten user's life security.Therefore, what the user was concerned about the most to electric heater is exactly safety problem, and this also is the problem that manufacturer payes attention to the most.In order to guarantee the safety in utilization of electric heater, manufacturer has carried out number of research projects on the Insulation Problems of electricity and water, and has done many improvement, has increased the cost of electric heater greatly, and insulant in case damage still can be leaked electricity electric shock accidents takes place.Therefore, the electric leakage problem of electric heater fails to find earth leakage protective solution a kind of both simple and reliable and that cost is low all the time.Chinese patent CN01262062.9; disclose a kind of protection against electric shock type electric heater, removed earth leakage circuit-breaker formula and leakage alarm from, and adopted a kind of both simple and reliable and the low anticreep spacer assembly of cost; thoroughly avoid electric shock accidents to take place, provide safety guarantee to the user.The scheme that adopts: a kind of protection against electric shock type electric heater, comprise electric heater, heating inner bag, water inlet pipe, outlet pipe, shell and anticreep spacer assembly, it is characterized in that described anticreep spacer assembly is for being connected on two insulation tubes compositions on water inlet pipe, the outlet pipe respectively.The length of described insulation tube is 53 times greater than the endoporus radius squared.Described two insulation tubes are connected on respectively on the water inlet pipe that exposes shell, the outlet pipe.Its cardinal principle is exactly to utilize the size of the state of the flowing through controlling resistance of water, makes current have safe voltage when contacting with human body, and then guarantees personal safety.But very inconvenience of the use of the prolongation of pipeline in practice.And the instant electric water heater is approved that by consumers in general but little just because of volume, the inner space is little because volume is small and exquisite now, causes the design of water heater protection against electric shock and safe handling to have big problem.
The utility model content
Technical problem to be solved in the utility model is to provide electric water heater electricity-preventing wall at above-mentioned prior art deficiency, reaches equally to have the purpose of safe voltage when current contact with human body, and smaller and more exquisite.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the utility model electric water heater electricity-preventing wall, comprise that water step-down body (1) and sealing are arranged at the connector (2) at water step-down body (1) two ends, be bolted with the pipe joint (3) that is used to connect inlet channel or outlet pipe on the connector (2), circulation pipe (11) is set in the described water step-down body (1), circulation pipe (11) is in series by plug (12) by a plurality of tube chambers that stack, and circulation pipe (11) both ends open communicates with connector (2) respectively.
The beneficial effects of the utility model are: in the described water step-down body circulation pipe is set, circulation pipe is in series by plug by a plurality of tube chambers that stack, the circulation pipe both ends open communicates with connector respectively, when guaranteeing sufficiently long flow path, the step-down body that is is more small and exquisite, can satisfy the small and exquisite instant electric water heater's of present volume protection against electric shock needs fully.
Description of drawings
Fig. 1, the utility model electric water heater electricity-preventing wall structural representation.
Among the figure, 1, water step-down body 2, connector 3, pipe joint 11, circulation pipe 12, plug.
The specific embodiment
Shown in Figure 1, the electric water heater electricity-preventing wall that the utility model provides, comprise that water step-down body 1 and sealing are arranged at the connector 2 at water step-down body 1 two ends, be bolted with the pipe joint 3 that is used to connect inlet channel or outlet pipe on the connector 2, in the described water step-down body 1 circulation pipe 11 is set, circulation pipe 11 is in series by plug 12 by a plurality of tube chambers that stack, and circulation pipe 11 both ends opens communicate with connector 2 respectively.
Owing in the described water step-down body circulation pipe is set, circulation pipe is in series by plug by a plurality of tube chambers that stack, the circulation pipe both ends open communicates with connector respectively, when guaranteeing sufficiently long flow path, the step-down body that is is more small and exquisite, can satisfy the small and exquisite instant electric water heater's of present volume protection against electric shock needs fully.Built-in externally all can finely be suitable for.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but on its shape or structure, do any variation; every have identical with a utility model or akin technical scheme, all within its protection domain.
Claims (1)
1, electric water heater electricity-preventing wall, comprise that water step-down body (1) and sealing are arranged at the connector (2) at water step-down body (1) two ends, be bolted with the pipe joint (3) that is used to connect inlet channel or outlet pipe on the connector (2), it is characterized in that: circulation pipe (11) is set in the described water step-down body (1), circulation pipe (11) is in series by plug (12) by a plurality of tube chambers that stack, and circulation pipe (11) both ends open communicates with connector (2) respectively.
