Abstract
The utility model discloses a mini electric water heater which comprises a container, a container cover, a water inlet tube, a water outlet tube and an electrothermal tube. The utility model is characterized in that a water inlet and a water outlet are both arranged at the upper part of the container. The electrothermal tube is a U-shaped electrothermal tube which has a corner in the middle part. A sealing ring and a baffle plate are arranged between the container and the container cover. The electrothermal tube is connected with a power through a leakage protector. A thermostatic controller can be also connected with the position between the electrothermal tube and the leakage protector. The utility model has the advantages of large heating area, even heating, high thermal efficiency, safety, reliability, small volume, convenient use and installation, etc., which can be used for hospitals, offices, workshops, families, etc. to wash hands and bowls.
Description
The utility model relates to a kind of domestic hot water device, exactly is a kind of miniature automatically controlled water heater.
Electric heater of the prior art roughly is divided into two big classes, and a class adopts crack water spray directly-heated type, and another kind of employing water storage is treated hot type.The shortcoming of directly-heated type maximum is that crack stops up easily, and in addition, water temperature, the water yield are subjected to the influence of tap water pressure size wayward, and storage-type electric water heater not only is not subjected to the influence of water quality, tap water pressure size, and security is better when using.
The purpose of this utility model is to design a kind of thermal efficiency height, simple in structure, safe and reliable miniature automatically controlled water heater.
Design of the present utility model is as follows: it comprises casing, case lid, water inlet pipe, outlet pipe and electrothermal tube; it is characterized in that the delivery port of the water inlet of water inlet pipe and outlet pipe is located at the top of casing; electrothermal tube adopts the U type electrothermal tube at turning, middle part; be provided with sealing ring and dividing plate between casing and the case lid, electrothermal tube links by earth leakage protective device and power supply.
The utlity model has that heating surface (area) (HS is big, homogeneous heating, thermal efficiency height, simple in structure, safe and reliable, volume is little, advantage such as easy to install.
The utility model has following accompanying drawing:
Fig. 1 water heater structural representation
Fig. 2 water heater vertical view
Fig. 3 water heater side view
Fig. 4 electrothermal tube schematic diagram
Fig. 5 circuit connects schematic diagram
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model structural representation, comprise casing 1, case lid 2, water inlet pipe 3, outlet pipe 4 and electrothermal tube 7, it is characterized in that the delivery port 6 of the water inlet 5 of water inlet pipe 3 and outlet pipe 4 all is located at the top of casing 1, can guarantee electrothermal tube 7 work in use under water all the time like this, in order to avoid electrothermal tube 7 dry combustion methods damage, so security is better.Certainly, the into water of must turning on the tap earlier when using for the first time is to there being water could connect power supply through outlet pipe 4 after shower nozzle flows out.When using later on, drive into earlier tap still connect earlier power supply all can, even cut off the water or forget and because of water is arranged in the water tank all the time, also can not burn electrothermal tube by the pass power supply.Between electrothermal tube 7 and earth leakage protective device 8, can be connected with radiator valve 9, like this, turn on the power switch when go to work every day, shut power supply when next, can have all day constant-temperature hot water to use.Radiator valve can adopt existing product or make by prior art, for example can adopt making such as the continuous adjustable temperature relay of JU-2 type, transformer, rectifying pressurizer, bridge-type thermostat and PTC pottery temperature-sensitive element.The PTC temperature-sensing element can be installed in the electrothermal tube thermometer hole 14 (referring to Fig. 4).Water temperature can be set, and for example can be set at 45 ℃.When water temperature in the water tank is lower than 45 ℃, relay adhesive, electrothermal tube heating; When water temperature was higher than 45 ℃, relay discharged, and electrothermal tube and power supply disconnect, thereby reach the temperature control purpose.Parts connecting relations such as the utility model temperature control, heating are referring to Fig. 5, and its median septum 10 can adopt copper coin, and earth leakage protective device 8 can be selected the commercially available prod for use, with radiator valve 9 be installed in dividing plate 10 above, electrothermal tube 7 be installed in dividing plate 10 below.
The utility model has provided the electrothermal tube 7(at turning, a kind of middle part referring to Fig. 4) its performance and basic configuration---the U type is similar to ripe large-scale electric heating shower, but because the middle part has added the turning, reduced the height of water tank 1 greatly, make the water heater microminiaturization, simultaneously, make the heating surface (area) (HS of U type pipe big, the water in the whole water tank can evenly be heated.In addition, the length of heating element heater in the electrothermal tube 7 that also can extend helps the heating wire that adopts diameter bigger, thereby prolongs the service life of electrothermal tube.Below be a kind of specific embodiments: 1500 watts of electrothermal tube power, the water heater volume is high 17cm, wide 15cm, thick 8cm, weigh about 1 kilogram, water temperature can reach 40 ℃ after connecting for the first time one fen half of power supply, and the about 2.5～3Kg of discharge per minute can be used for hospital, office, wash one's hands in the workshop and family washes one's hands, wash the dishes and other needs the place of hot water.The front of water tank 1 can be designed to circular arc (referring to Fig. 2), can pass through the hook 11(of water tank 1 back referring to Fig. 3) hang on the wall, install very convenient.
Be provided with sealing ring 13 and dividing plate 10 between casing 1 of the present utility model and the case lid 2, available screw is installed in dividing plate 10, sealing ring 13 above the casing 1, and water tank is sealed.Dividing plate 10 can adopt copper coin, and is safe in utilization to guarantee with power ground ground connection.Also can add cartridge fuse in circuit, like this, the utility model just will have earth leakage protective device, ground connection, the measure of cartridge fuse retrocession, can guarantee being perfectly safe of user.Case lid 2 be installed in casing 1 above, earth leakage protective device 8, radiator valve 9, electrothermal tube 7 etc. are among the sealing working environment, make water heater form complete machine and good looking appearance.
