Detailed Description
To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
As shown in fig. 1-2, the instant electric water heater with multi-channel parallel pipelines of the present application comprises a water heating assembly 1, a housing 2 and a controller 3. The water heating component 1 is fixed on the shell 2, and the water inlet pipe 11 and the water outlet pipe 17 of the water heating component 1 extend out of the shell 2 so as to be connected with an external water pipe. The shell 2 is isolated from the water heating component 1 by adopting heat insulation materials. The controller 3 is installed on the shell 2 and connected with the sensor probe and the electric heating tube 14 arranged on the water heating component 1 so as to detect and control the safety of the electric appliance of the device. The controller 3 is connected to the power cord 4 so that the entire device receives power when the power cord 4 is plugged into an outlet.
As shown in fig. 2, the water heating assembly 1 includes a liquid distribution pipe 12, a parallel pipeline 13, an electric heating pipe 14 and a liquid collection pipe 15, wherein a water inlet pipe 11 is connected with the liquid distribution pipe 12, and a water outlet pipe 17 is connected with the liquid collection pipe 15. A plurality of parallel pipelines 13 are connected between the liquid separating pipe 12 and the liquid collecting pipe 15 at intervals, and the electric heating pipe 14 heats water in the parallel pipelines 13. As shown in fig. 2, the electric heating tube 14 may be disposed against the outer wall of the parallel pipeline 13, and indirectly transfer heat through the wall of the parallel pipeline; or directly arranged inside the parallel pipe 13 to be heated by being directly contacted with water. The electric heating tube 14 has an insulating property, and is electrically leak-proof when it is in contact with the parallel pipe 13. One or at least two electric heating pipes 14 may be disposed on the water heating assembly 1, and need to be laid according to the heating power of the electric heating pipes 14.
The liquid separating pipe 12 and the liquid collecting pipe 15 are provided with a plurality of small holes which are convenient to form close fit with the parallel pipeline 13, and form a sealing channel with the parallel pipeline 13 by adopting the modes of threaded connection, bonding or welding and the like so as to prevent water leakage. The liquid separation pipe 12 and the liquid collection pipe 15 may be a metal material or an organic material. The liquid separating pipe 12 and the liquid collecting pipe 15 can be linear type or curved type, and are mainly matched with the shell 2, so that the technical advantages of small occupied space and attractive appearance are achieved. It may also be of a spiral configuration to further reduce the space occupied by the water heating assembly 1. The radial shape of the liquid separating pipe 12 and the water collecting pipe 15 can be circular pipe, oval pipe, or polygon such as triangle.
The parallel pipeline 13 is connected with the liquid separating pipe 12 and the liquid collecting pipe 15, and a sealing structure is formed between the parallel pipeline and the liquid separating pipe 12 to prevent water leakage. The parallel pipes 13 may be spaced apart from each other and may have an overall cross-sectional shape as shown in fig. 3. That is, the parallel conduits may be separate conduits arranged at intervals, or separate flow channels formed in an integral component. The parallel pipes 13 may be made of metal or organic material, and may have a linear or curved axial shape. The inner cross section shape and the outer cross section shape of the parallel pipeline can be circular tubes, elliptical tubes or polygons such as triangles.
Preferably, in order to make the water flowing through the parallel pipes heated more uniformly, as shown in fig. 2, a baffle plate 16 may be provided in the liquid separating pipe 12 or the liquid collecting pipe 15 or both to separate the water flowing through the channel. The baffle 16 may be a valve in the form of a metal or plastic sheet, and the arrangement of the baffle further increases the path of the water therethrough, increasing the heat energy available to the water.
Preferably, the flow baffle 16 may be provided as an electrically controlled valve, and the inlet pipe 11 and/or the outlet pipe 17 may also be provided with a valve. As shown in fig. 4, when water flows in from the position a, the electric control valve is opened, the valve at the position C is closed, and then the water is distributed by the liquid distribution pipe, uniformly enters each parallel pipeline, absorbs the same heat, enters the liquid collection pipe after reaching the same water temperature, and flows out from the end B. When the electric control valve is closed, the B position is closed, so that water only flows through the liquid separating pipe section from the A end to the valve, then enters the parallel pipeline to absorb heat and raise the temperature, is distributed by the liquid collecting pipe, flows through the parallel pipeline from the electric control valve to the C end, and finally flows out through the C end. Therefore, the distance of water flowing through the parallel pipelines is lengthened, the heat of the obtained heating pipe is increased, and the water temperature rises along with the increase of the heat. Therefore, the controller 3 controls the electric control valve to realize that the instant electric water heater can flow hot water with different temperatures.
In this application, parallel pipeline adopts the parallel pipeline of diameter no more than 4 mm's little passageway, and the wall thickness is no more than 0.4 mm. For example, if a parallel pipeline with small channels and an outer diameter of 4mm and a wall thickness of 0.4mm is used and the flow cross section is consistent with that of a 4-minute pipe, about 16 parallel pipelines with small channels are required to replace the 4-minute pipe. Because the section of the water flowing through becomes smaller, the flowing Reynolds number is increased, the heat exchange efficiency of the water and the electric heating pipe is favorably improved, 16.8kW can be distributed to 16 small-channel parallel pipelines, the required power consumption on each pipeline is about 1kW, and the safety and reliability of the instant electric water heater are improved.
The instant heating type electric water heater with the multichannel parallel pipelines utilizes the parallel pipelines of the plurality of small channels to shunt water, so that the flow disturbance of water flow is aggravated, a heat exchange effect is formed between the water flow and the electric heating pipe or the heating surface, the distribution of electric heating power is realized on the plurality of small channels, and the potential safety hazard of electric appliances brought by high power is reduced.
Although the embodiments disclosed in the present application are described above, the descriptions are only for the convenience of understanding the present application, and are not intended to limit the present application. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
