Abstract
The utility model relates to a multifunctional miniature quick water heater composed of a heat exchanger, a water inlet, a water outlet, a temperature controller and a casing. The utility model is characterized in that the outer surface of the heat exchanger is coated with an electric heating membrane which is electrically connected with a power supply. The surface of the electric heating membrane is coated with heat insulation material. A water pressure automatic control device is installed between the water inlet and the heat exchanger. The utility model has less power consumption and saves electricity of at least 35% more than the similar metal heating wires. The utility model has the advantages of high thermal efficiency, adjustable temperature, small size, light weight, good insulating performance, safety, reliability, low cost, long service life and low price and is suitable for the aspects on showering, washing hands, washing dishes, boiling water, etc.
Description
The utility model relates to heat exchanger, particularly the quick-acting water heaters of multifunction micro.
Technology in the past is made up of heat exchanger, water inlet, delivery port, temperature controller and shell.The general metal electric heating silk that adopts makes the cold water heating by heat transfer then as heater element, resembles the electric kettle generally sold in market, shower etc.It is big that the water heater of this structure exists consuming electric power, fragile, and especially heating wire very easily blows, thereby service life is short; The volume ratio of water heater is bigger simultaneously, and the comparison heaviness seems; Also there are shortcomings such as electric leakage is dangerous, the thermal efficiency is low.
The purpose of this utility model provides a kind of quick-acting water heaters of multifunction micro that can overcome above-mentioned shortcoming.
The utility model is finished as follows: wrap one deck Electric radiant Heating Film at the heat exchanger outer surface, as heating, this Electric radiant Heating Film is electrically connected with power supply; On the surface of Electric radiant Heating Film one deck heat-barrier material is arranged, put the case of insulation then; For flow and the flow velocity of controlling water in the heat exchanger, make the water of outflow just in time be heated into needed temperature, so the hydraulic pressure self-con-tained unit is installed between water inlet and heat exchanger.
Heat exchange body of the present utility model adopts glassware, and its outsourcing last layer Electric radiant Heating Film is electrically connected with it with circuit auto-control protective device, and this device is connected with power supply then.Wrap one deck heat-barrier material again at the Electric radiant Heating Film outer surface, inner can is installed then, integral body is installed shell again.
The utility model has following advantage than conventional art: 1, little power consumption more than 35%, does not need preheating just can use at any time than similar metal electric heating silk economize on electricity; 2, Electric radiant Heating Film encases glassware, and heat transfer area is big, thus thermal efficiency height, and Controllable Temperature; 3, volume is little in light weight, and the cost low price is cheap; 4, good insulation preformance, safe and reliable; 5, long service life.Aspects such as being applicable to the electric heating shower, washing one's hands, washing the dishes and boiling water.
Further describe below in conjunction with accompanying drawing.
Fig. 1 is the utility model general assembly drawing.
Fig. 2 is the structure chart of hydraulic pressure automatic controller.
Fig. 3 is a circuit auto-control protective schematic diagram of device.
With reference to Fig. 1, the quick-acting water heaters of multifunction micro are made of with shell (8) heat exchanger (1), water inlet (9), delivery port (10), temperature controller (5).Heat exchanger in the present embodiment (1) main body is a glassware, and outer surface has one deck Electric radiant Heating Film (2), and this film (2) is electrically connected with power supply.In order to control the electric current and the voltage of Electric radiant Heating Film (2),, between Electric radiant Heating Film (2) and power supply, there is circuit auto-control protective device (4) to be electrically connected perhaps in order to keep voltage stabilizing power supply and safeguard protection.Also wrap one deck heat-barrier material (6) on Electric radiant Heating Film (2) surface, this heat-barrier material (6) generally adopts asbestos, is installed in plastics inner can (7) lining.In order to keep interior hydraulic pressure of heat exchanger (1) and water temperature to decide as required, then between water inlet (9) and heat exchanger (1), hydraulic pressure self-con-tained unit (3) is installed.Shell (8) adopts stainless steel to make.
With reference to Fig. 2, hydraulic pressure self-con-tained unit (3) is made of entrance point (11), the port of export (12), cone spool (13) and spring (14), and entrance point (11) is threaded with the port of export (12) and seals.The port of export (12) internal cavity is a conical cavity, and the rear portion is a cylinder, and cone spool (13) is slidingly matched with it, and spring (14) is connected with both, and an end embeds in cone spool (13) groove.
