Abstract

The utility model pertains to an electric heating water device and relates to a water heater. The utility model adopts a ceramic exothermic padding which is arranged in the middle of a box body, a lead wire end of a power supply of the box body is penetrated out of a rectangular mesh on the left side of the box body and arranged in a seal cavity, a lead wire of a power supply of the ceramic exothermic padding leads out from the seal cavity, and the space of the seal cavity is filled with heat resistant glue. The inner walls of the box body and a box cap are all arranged with serrate odd dividing strips and even dividing strips, and the left side of the odd dividing strips and the right side of the even dividing strips both have flow swivel ports which cause the two sides of the in the ceramic exothermic padding box form a grid winding stream leading cavity. After cold water enters into the box from a water inlet, the cold water is evenly distributed on the two sides of the ceramic exothermic padding, the stream continuously processes an S-shaped circulation along the grid winding stream leading cavity on the two sides of the ceramic exothermic padding, and water is continuously heated when flowing and water temperature rises rapidly until water flows out of a water outlet. The utility model is particular applicable to the fields of chamber pots, medical apparatus, drinking machines and scientific experiments.

Description

A kind of water heater

Technical field

The utility model belongs to the device of electrical heating water, relates to a kind of water heater.

Background technology

To adopt heating alloy usually be traditional water storage box type of heater element to water heater in being seen at present " Cleaning device for closet " product.There are several shortcomings in this water heater: 1, the thermal efficiency is low, generally has only 50%, and heat time heating time is long, needs preheating or whole day to keep water temperature etc. to be used, and power consumption is big.2, water temperature is regulated inconvenience, changes slowly.For example, the water temperature that preheating is good in the water tank is 40 degree, and it is too hot that the user dislikes, and turns down leaving water temperature, can not realize at once, even because this moment heater stop power supply, also to wait the degree of 40 in water tank water to flow out, cold water replenishes inlet water tank, temperature ability is very long gets off.Otherwise the water temperature that preheating is good in the water tank is 30 degree, and it is too cold that the user dislikes, heighten leaving water temperature, even heater full power heating this moment also will have a time course that full water case water temperature is improved, and the water of 30 degree is also continuously outflowing the constantly additional inlet water tank of cold water.Therefore these two kinds situations of regulating temperature are to realizing in " Cleaning device for closet " that use above-mentioned water tank type heater several absolutely not seconds.3, at present common " Cleaning device for closet " water tank volume is many about one liter, and flushing flow rate is at 500 milliliters to 700 milliliters during use, and the warm water in 1 to 2 minute storage tank has just been used up, and subsequent water temperature is just more and more lower.4, volume is big, and one liter water tank has accounted for half of " Cleaning device for closet " movement.

Summary of the invention

The purpose of this utility model is to exist not enoughly at the water heater of above-mentioned " Cleaning device for closet ", designs that a kind of volume is little, the thermal efficiency is high, the convenient water heater rapidly of adjustment.

The utility model is a kind of water heater, it is characterized in that adopting ceramic heating plate place box body, with the centre of lid.The power supply lead wire end of ceramic heating plate passes from box body left side oblong aperture and places annular seal space.In annular seal space, there are rubber seal, metal fixing, its two to have screw to compress between ceramic heating plate and the box body.The power supply lead wire of ceramic heating plate is drawn from annular seal space, and heat-proof silica gel is filled up in the space of annular seal space.The lower right side of box body has a water inlet; Top is surveyed on the right side of box body a delivery port.The inwall of box body, lid all has zigzag odd number of points parting bead and even number divider, and the left side of odd number of points parting bead has current to rotate mouth, and there is current rotation mouth on the right side of even number divider, makes the both sides composition of ceramic heating flake in the box delete lattice shape complications diversion cavity.One Thermal Cutoffs groove is arranged on the outer wall of lid, Thermal Cutoffs tightly is stuck in the groove with jump ring.There is a temperature controller installing rack box body delivery port top, and there is an angle box body outside, and two fixing feet are arranged.

The utility model has the advantages that: the water that 1, enters heater is separated the both sides that the chamber is evenly distributed on ceramic heating flake, and current are constantly done the motion of S shape to outlet simultaneously, make the heating process of water more reasonable, and the thermal efficiency is more than 95%.2, heat up expressly, embodiment heater flow is 500 milliliters of per minutes, when ceramic heating plate power is 1500W, and can be that the water of 10 degree are heated to 40 degree 4 seconds with water inlet.3, water temperature is easy to adjust, and the embodiment water temperature is turned down and can be realized in 1 to 2 second to heightening between 40 degree at 35 degree.4, the stable hot water of output temperature for a long time.5, volume is little, and the embodiment plastic casing is the 78*80*18 millimeter.

For the ease of understanding the utility model, the utility model is further specified below in conjunction with the drawings and specific embodiments.
