Abstract
The utility model relates to an external-plugging electric heating device for an integral insulation water tank. The utility model belongs to an electric-heating temperature control device which is installed by making use of plugging mode. The utility model is suitable for the integral insulation water tank of a mouth-opening type water heater. The utility model has the advantages of simple structure, convenient installation, convenient maintenance, small heat loss and no installing angle limit. A sealing ring (2) is sheathed on the circular hole of the inner wall of an insulation tank (1), a seat body (4) is directly inserted into the sealing ring (2) and is installed on the insulation tank, and an electric-heating tube (3) and a heat controller (5) are installed at the seat body (4). The external exposing part of the utility model is protected by a cover (7).
Description
The utility model relates to and a kind ofly is installed in electric calorifie installation on the integral heat insulation water tank with inserted mode.
The known electric calorifie installation that is used for the integral heat insulation container generally is to be fixed on the container in the mode that screw thread or ring flange connection connect.This structure exists maintenance inconvenience and the bigger problem of heat loss.The split outside plug type solar water heater auxiliary electro-heat device that Chinese patent application ZL95234656.7 proposes in use, because of the operate outside of electrothermal tube at water tank, make heated medium form circulation and carry out the heat conduction, if, can make electrothermal tube cross cause thermal damage because of circulation is obstructed, bubble is assembled near electrothermal tube so its level is installed and used.
The purpose of this utility model provides a kind of outside plug type electric calorifie installation of the vented water heater's of being used for integral heat insulation case, can directly insert electric calorifie installation in the bottom of incubator, and electrothermal tube enters in the water tank, and setting angle is unrestricted.
The outside plug type electric calorifie installation that is used for the integral heat insulation water tank that the utility model relates to adopts following structure to realize: known by Fig. 1 electrothermal tube (3), thermostat (5) and terminal board (6) are housed on the pedestal (4).Be with sealing ring (2) on the circular hole of incubator (1) inwall, the internal diameter of the external diameter of pedestal (4) one ends and sealing ring (2) closely cooperates, and the pedestal that electrothermal tube, temperature controller are housed directly can be inserted sealing ring, and be installed on the incubator.Cover (7) covers the other end in pedestal (4), and exposed parts is played protective action.
An end of knowing electrothermal tube (3) by Fig. 2 is by the L of temperature controller (5) connecting terminal plate (6), the other end and shell connect respectively N,
Power line passes the hole connecting terminal plate (6) of cover (7) bottom and powers to electrothermal tube (3).When water temperature reaches design temperature, temperature controller (5) deenergization, anti-defervescence is burnt.
Because the utility model adopts inserted mode to install, and electrothermal tube enters in the incubator, has simple in structurely, and installation and maintenance are convenient, and heat loss is little, and the unrestricted characteristics of setting angle.
