Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an A-A cross section view among Fig. 1;
Be described in further detail below in conjunction with the content of accompanying drawing this.
The specific embodiment
With reference to Fig. 1, shown in Figure 2, water tank upper casing 1 interconnects by screw thread or buckle-type with water tank lower casing 2 forms a complete heater box, sealing ring 8 seals, heat-conducting plate 6 is fixed on base plate 14 outsides of water tank lower casing 2, the hole that the fixed interface of electric heating tube 3 passes on the base plate 14 is fixed on the heat-conducting plate 6, temp.-determined type temperature controller 7 also is fixed on the heat-conducting plate 6, and the temperature of water is passed to temp.-determined type temperature controller 7 by heat-conducting plate 6.
Non-electronic temperature adjusting structure is fixed on the water tank lower casing 2 by the heat resistance plate 4 in band heat transfer hole 15, stick together mutually with activity thermal resistance blade 5 planes, the newel hole that central shaft on the activity thermal resistance blade 5 passes on the base plate 14 of water tank lower casing 2 is connected with temperature adjustment button 10 below the bottom 13, Simmer ring 9 be used for spool and the hole between sealing.
Utilize and change exchange rate, realize a kind of non-electronic temperature adjusting structure that temp.-determined type heat-storage water heater can preset temperature, water storage tank is divided into two-layer up and down by heat resistance plate 4 and activity thermal resistance blade 5 in the water heater water storage casing, be provided with electric heating tube 3 and temp.-determined type temperature controller 7 and water inlet 12 in the less lower floor, this part is as the heating temperature zone, the hot-zone is store as thermal-arrest in bigger upper strata, size adjustment by 5 pairs of heat transfer hole 15 areas of guiding mechanism drive activity thermal resistance blade of being provided with from the water storage tank external body, control hot and cold water rate of heat exchange, thereby the water temperature of having controlled lower floor arrives temp.-determined type temperature controller 7 and turn-offs the speed of temperature (kick temperature), reach indirect control, realized regulation and control whole water retention zone water temperature to length heat time heating time.
The utility model is the adjustment that realizes like this water temperature: after water is full of water heater by the water inlet on the water tank lower casing 2 12, close after water valve (external) connects power supply, hang down the temp.-determined type temperature controller because of initial water temperature and be in conducting state.3 heating power feedwater of electric heating tube are heated, and when heat transfer hole 15 areas were in maximum, heated water lightened because of proportion before energising, make progress automatically through heat transfer hole 15, with cold water mix, because of cold water is heavier than hot water, automatically downwards.Enter the heating temperature zone and just mix by heat transfer hole 15 at heated water, because heat transfer hole 15 is in maximum rating, the hot and cold water exchange velocity is very fast, water temperature in the lower floor heating temperature zone is very fast because of cold water sinks, it is the longest that temperature is raised to time of the temperature that 7 take-offs of temp.-determined type temperature controller disconnect, the time that causes electric heating tube 3 to be heated is the longest, thereby final water temperature is in the highest state relatively.
Otherwise the adjusting when heat transfer hole 15 by temperature adjustment button 10 makes activity thermal resistance blade 5 15 shutoff of heat transfer hole, when heat transfer hole 15 is in closed condition, heat exchange is the slowest, the water temperature of lower floor heating temperature zone, mixing because of no cold water, it is the shortest that temperature is raised to the time of the temperature that 7 take-offs of temp.-determined type temperature controller disconnect, and the time that causes electric heating tube 3 to be heated is the shortest, thereby final water temperature is in relative minimum state.
Therefore by adjusting the size in heat resistance plate 4 heat transfer holes 15, promptly changed rate of heat exchange, preset the purpose of adjusting water temperature thereby reached.Utilize the change exchange rate to realize that the heat-storage water heater presets the temperature adjusting structure of adjustment than greatly simplifying with the structure of electronic type preset temperature adjustment to water temperature obviously, the reduction of its cost is apparent.
After the power of the volume of water storage tank and electric heating tube 3 was determined, the control range of the highest water temperature and minimum water temperature was mainly by three factors decisions:
1, temperature value is turn-offed in the take-off of temp.-determined type temperature controller;
2, the position of heat resistance plate device, i.e. the separation ratio of two sheaf spaces up and down;
3, the maximum area in heat transfer hole, the big more upper limit maximum temperature of area is high more, even can surpass the shutoff temperature.
