Abstract
The utility model relates to a power supply line structure of an indoor electric heater. The technical problem to be solved lies in that the provided power supply line structure should have the advantages of facilitating the heater assembly, reducing the assembly workload and generating no interference effect when a plurality of electric heaters are used. The technical scheme is as follows: a power supply line structure of an electric heater comprises a plug, a socket, and a live wire, a null line and a ground wire, which are respectively connected between the plug and the socket, the power supply line structure is characterized in that a conducting wire is led out from the live wire end of the plug to be sequentially connected with a temperature controller and a heating plate live wire of the electric heater; and a conducting wire is led out from the null line end of the socket to be connected with a heating plate null line of the electric heater; a third conducting wire is led out from the ground wire end of the socket to be connected with the outer frame of the electric heater; the live wire and the null line are standard lines with cross sections of 1.0-5.0mm<2>; and the lengths of the live wire and the null line are 200-1500mm.
Description
Technical field
The utility model relates to a kind of household appliance, especially a kind of power line structure of indoor electric heating device.
Background technology
Arrive season in midwinter, and various resisting cold heating systems have become necessity configuration of each enterprises and institutions office space; Electric heating device wherein (especially adopting the warmer of carbon fiber heating plate) because of plurality of advantages such as its heating efficiency are high, easy to use, has obtained widespread usage.
Yet the power line structure of existing electric heating device is very unreasonable, only is provided with two leads external power source is introduced; Need dispose zero line and temperature control lead separately during the electric heating device assembling, increase the assembly work amount; In addition, when many warmers of same indoor use, (promptly second warmer introduced power supply from the supply socket of first warmer to " queuing type connects method " of adopting usually, and the 3rd warmer introduced power supply from the attaching plug of second warmer; And the like) easily because of the fault of a warmer, have influence on the normal use of other warmers.
The utility model content
The purpose of the utility model provides a kind of improvement of electric heating device power line structure; This power line structure should be able to overcome the deficiency of above-mentioned background technology, has the advantages that to make things convenient for warmer assembling, minimizing assembly work amount, many uses not to have mutual interference effect.
The technical scheme that the utility model adopts is: a kind of electric heating device power line structure, comprise plug, socket and be connected to plug and socket between live wire, zero line and earth connection; It is characterized in that: the live wire end of said plug is also drawn a lead and is connected with the heating board live wire of thermostat and electric heating device successively; The zero line side of said socket is also drawn the heating board zero line of another lead and electric heating device and is connected.
The grounding terminal of said socket is also drawn the housing of a privates and electric heating device and is connected.
Described live wire and zero line are the graticule of 1.0 ~ 5.0 square millimeters of cross sections.
The length of described live wire and zero line is 200 ~ 1500mm.
The operation principle of the utility model is: lead and the live wire of plug end of a terminated line of this electric heating device heating board through being connected in series thermostat connected, and the other end is through the zero line connection of lead with socket end, thus normal power-up work; Live wire in the power line structure and zero line provide power supply through socket (socket cooperates with adjacent electric heating device plug) for adjacent electric heating device as total live wire and total zero line.
The beneficial effect of the utility model is: because the heating board power supply and the main power source (main live wire and main zero line) of this electric heating device are relatively independent; Therefore when heating board electric loop contingency breaks down; Can not influence the main power source power supply; Also just guaranteed the operate as normal of adjacent electric heating device, promptly many electric heating devices use also not interference effect each other simultaneously.In addition, the utility model has disposed the thermostat, earth connection, plug and the socket that connect through lead respectively, brings great convenience for the assembly work of electric heating device, has also reduced the assembly work amount, has improved assembly work efficient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Electric heating device power line structure shown in Figure 1 comprises that plug 1, socket 5 and the live wire 4, zero line 8 and the earth connection 9 that between plug and socket, are connected respectively (have a sheath to coat ignition line, zero line and earth connection in addition; Clear for drawing, omit sheath among the figure); Socket is fixed on the electric heating device usually, and plug is the movable end of retractable, is beneficial to electric heating device and carries out the power supply connection.
The above structure all power supply wiring with existing electric heating device is identical.
The utility model is also drawn a lead at the live wire end of said plug, and this lead is connected with the heating board live wire 3 of thermostat 2 and electric heating device successively, for the heating board of electric heating device is introduced power supply; The zero line side of said socket is also drawn another lead 6 of connecting with the heating board zero line of electric heating device, and then makes the power supply of heating board constitute the loop.Said thermostat is used to control the heating board of electric heating device, can cut off the power supply automatically when making the electric heating device surface arrive assigned temperature, and not influence the work of other electric heating devices that are connected with this electric heating device.
Also be connected an earth connection 9 between said plug and the socket; The grounding terminal of said socket is also drawn the privates 7 of the housing connection of an electric heating device.
The specification of described live wire and zero line can confirm as required that preferred specification: cross section is 1.0 ~ 5.0 square millimeters a graticule.
The length of described live wire and zero line can confirm as required that preferred length is 200 ~ 1500mm.
The equal buyable of plug in the utility model, socket, thermostat and other all components and parts obtains.
