Abstract

The utility model relates to an electric water heater with a hot water capacity display, which comprises a housing, an inner liner, a heating device, a control device, and a temperature sensor, wherein, the temperature sensor is arranged on the outer wall of the inner liner. When external cold water is supplemented into the inner liner and the local water temperature in the inner liner generates large fluctuation, the fluctuation is conducted to the temperature sensor and is weakened through the wall of the inner liner, so the temperature sensor obtains a more accurate water temperature value. According to the measured water temperature, the utility model is favorable to display the residual hot water capacity correspondingly.

Description

The electric heater that the band hot water amount shows

The utility model belongs to household electrical appliance; Be specifically related to improvement to electric heater.

Before the utility model was made, what use on electric heater at present all was temperature indicator; Temperature indicator is divided into mechanical type thermometer and electronic digital display.Mechanical type thermometer contact inner bag inside a bit utilizes the principle of the different shrinkage factor of bimetal leaf to drive the water temperature height that pointer is indicated inner bag; The electronic digital pipe shows it is that temperature sensor is placed on the inner perception water temperature of inner bag, by the electronic device conversion, shows the water temperature of inner bag with digital pattern.Because the variation of water temperature is not a kind of linear change, so directly show water temperature in the inner bag in the process of using, the user uses and inconvenience; Manufacturer prepares data presented is changed into by the corresponding next hot water amount demonstration of the water temperature in the inner bag now.Realize that this technical scheme can only convert with the water temperature of temperature sensor perception inner bag; But all be at present that temperature sensor is placed on the inner directly temperature of perception water of inner bag, because water heater constantly need replenish cold water in inner bag in the process of using, so the temperature of sensor senses is not the mean temperature of water when cold water just enters water heater, so give demonstration according to the hot water amount of water temperature correspondence inaccurate and make and show and bring fluctuation that result of use is not good.

The purpose of this utility model is for addressing the above problem, provide a kind of can be accurately, water temperature in the perception inner bag stably, be fit to the electric heater that the corresponding band hot water amount who shows the delayed heat water yield shows.

For the utility model that achieves the above object is achieved in that a kind of electric heater that shows with the hot water amount, comprise housing, inner bag, heater, control device, temperature sensor, temperature sensor places the outer wall of inner bag.

The electric heater that above-mentioned band hot water amount shows is provided with a plurality of temperature sensors, places the diverse location of inner bladder outer wall.

Advantage of the present utility model and good effect are, temperature sensor is arranged on the outer wall of inner bag, when outside cold water replenished into inner bag, the local water temperature in the inner bag produced bigger fluctuation, but this fluctuation when being transmitted to temperature sensor by wall of inner container this fluctuation weaken; So the fluctuating temperature of temperature sensor perception is little.If the diverse location of wall is provided with a plurality of sensors outside the tank, with the water temperature value integrated treatment of each sensor senses, the water temperature value that obtains so will be more accurate.Can help like this according to the corresponding delayed heat water yield that shows of the water temperature that records.

Below in conjunction with accompanying drawing the utility model is described in further details.

Fig. 1 is the structural representation of an embodiment of the utility model.

As shown in Figure 1, a kind of electric heater that shows with the hot water amount comprises housing 1, inner bag 2, heater 3, control device 4, temperature sensor 5, and wherein temperature sensor connects control device, temperature sensor is moved to the outside from inner bag inside, be arranged on the outer wall of inner bag 2.

In order to obtain water temperature more accurately, a plurality of temperature sensors 5 are set on the diverse location of wall outside the tank, the utility model example is provided with 2 temperature sensors.

The position of temperature sensor can be arranged on the best position according to experiment.

With the water temperature average computation of a plurality of temperature sensor perception, again through the chip correspondence in the control device, be converted into pure hot water amount and show; The convenient use.

Claims

1. an electric heater that shows with the hot water amount comprises housing (1), inner bag (2), heater (3), control device (4), temperature sensor (5), and it is characterized in that: described temperature sensor (5) places the outer wall of inner bag (2).

2. the electric heater that band hot water amount according to claim 1 shows, it is characterized in that: the electric heater that above-mentioned band hot water amount shows is provided with a plurality of temperature sensors (5), places the diverse location of inner bladder outer wall.
