Abstract
The utility model relates to an electric water heater, belonging to electric heating technology. The electric water heater comprises an electric heating device arranged inside a water bin, and is characterized in that the water bin is also provided with a flow limiting pipe along the longitudinal direction; and the electric heating device is positioned inside the flow limiting pipe, the bottom of which is provided with a water inlet, and the top part of the flow limiting pipe is open. The electric water heater has the benefits that the electric water heater can more rapidly raise the water temperature in the water bin; the water temperature distribution inside the water bin is even, so that the water temperature difference between the upper layer and the bottom layer is reduced as much as possible; and for a water heater used for providing hot water for shower bath, the water temperature of output water flow can be ensured to be consistent.
Description
Technical field
The utility model relates to electroheat technology.
Background technology
The structure of electric heater is to be provided with electric heating device in the sump in the prior art, and heater element is positioned at the sump middle part mostly.When electric heater is worked, because proportion relation, be heated the top that is raised to waterborne of device, replenish by the cold water of close heater element, form convection current (arrow of Fig. 1 is represented water (flow) direction) as shown in Figure 1, be heated to predetermined temperature up to the water of whole sump.The weak point of this mechanism is that the water temperature of sump bottom always is in minimum, and the water temperature on top is always the highest, and the water that bottom temp is minimum always is difficult to be heated device and directly heats.The efficient of heating is not high, time-consuming longer on the one hand, and, when the temperature-detecting device that is arranged on sump middle part or top detects that water temperature reaches predetermined temperature and when stopping to heat, the water temperature of sump bottom is lower than this predetermined temperature often, promptly, generally speaking, be not heated to predetermined effect.
The utility model content
Technical problem to be solved in the utility model is, a kind of electric heater is provided, and with respect to prior art, firing rate is faster, and efficient is higher.
The technical scheme that the utility model solve the technical problem employing is that electric heater comprises the electrothermal device in the sump, it is characterized in that also be vertically arranged with current limiting tube in the sump, electrothermal device is arranged in the current limiting tube, the bottom of current limiting tube is provided with water inlet, open-top.
Described current limiting tube is arranged on the sump bottom, and water inlet is arranged at the contact position of current limiting tube and sump bottom.The material of current limiting tube is optimum heat conduction material.The sump bottom also is provided with the water channel member, and the water channel that the water channel member forms is communicated with the water inlet of current limiting tube.Described water channel member is a dividing plate, and described dividing plate ring-type is arranged on the current limiting tube bottom.Described dividing plate has through hole.
The beneficial effects of the utility model are, can improve the water temperature in the sump faster, the distribution of water temperature in the sump is even, has reduced the water temperature difference of upper strata and bottom as much as possible, for the water heater that hot water is provided for shower, guaranteed the uniformity of the water temperature of output current.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the schematic diagram of prior art of the present utility model.
Fig. 2 is the schematic diagram of embodiment 1 of the present utility model.
Fig. 3 is the schematic diagram of embodiment 2 of the present utility model.
The specific embodiment
Embodiment 1: referring to Fig. 2.
The utility model is provided with current limiting tube 2 in sump, heater element 1 is positioned at the inside of current limiting tube 2, and the below of current limiting tube 2 is provided with water inlet, open-top.Current limiting tube 2 is arranged on the sump bottom, and water inlet is arranged at the contact position of current limiting tube and sump bottom.The function of described current limiting tube is the convection current approach that the temperature difference causes in the restriction sump.The concrete course of work is: after the heater element in the current limiting tube heated near water, heated liter waterborne went out current limiting tube from open overhead stream, because the effect of current limiting tube, the heated that part of water of replacement, the overwhelming majority is the water at low temperature from the bottom, is heated again.Circulate with this, the water of having guaranteed the most close heater element is always from the minimum sump bottom of temperature, thereby realizes that whole water temperature as much as possible evenly distributes.
Embodiment 2: referring to Fig. 3.
Present embodiment has increased water channel member 3 on the basis of embodiment 1, water channel member 3 is used for forming water channel in the sump bottom, and the inlet of water channel is evenly distributed in bottom everywhere as far as possible, and outlet connects the water inlet of current limiting tube 2.A kind of simple water channel member is a dividing plate that is parallel to the sump bottom surface, is water channel between dividing plate and sump bottom surface.The radius of dividing plate be approximately sump bottom surface radius half get final product.Perhaps,, be evenly distributed with some apertures on the dividing plate, make the water of sump lower part enter current limiting tube as far as possible uniformly as an improvement.
