Description

Technical Field

[0001] The invention relates to the field of electric water heaters, and in particular to a household multifunctional water-boiling device. Background Art

[0002] The electric water heater for boiling water at home usually consists of only one or two independent inner tanks. Each time the water is boiled, all the water in the inner tank must be heated at the same time. The heating speed of the water depends on the size of the inner tank. Under the same heating power, the larger the capacity of the inner tank, the slower the boiling speed. When hot water is needed temporarily, all the water in the inner tank must be heated temporarily, which not only has a slow boiling efficiency, but also wastes a large amount of hot water that is not needed. The prior art will separate the inner tank into two independent inner tanks, but in the same installation space, the water capacity of the two independent inner tanks is much smaller than that of a single inner tank, and a large amount of hot water cannot be obtained. In addition, the prior art will also install a An independent small inner tank is provided, and an independent heating tube is installed in each of the two inner tanks of the inner and outer layers. Not only can the outer inner tank and the heating tube be used to boil a large amount of hot water at a time, but the inner inner tank and the heating tube can also be used to quickly boil a small amount of hot water at a time to meet different usage experiences.

[0032] A household multifunctional water-boiling device of the present invention is mainly composed of an inner tank 2, a first heating tube 31, a second heating tube 32 and a sleeve 4. In the conventional water-boiling mode, the inner cavity space of the sleeve 4 is connected to the inner cavity space of the inner tank 2 to form a large-capacity water-boiling device. At this time, the first heating tube 31 and the second heating tube 32 perform a large amount of hot water boiling work in the inner tank 2. In the fast water-boiling mode, the sleeve 4 is sleeved on the adapter 3 to form a small-capacity water-boiling device with the first heating tube 31 and the second heating tube 32. At this time, the first heating tube 31 and the second heating tube 32 perform a small amount of hot water fast in the sleeve 4. The utility model can quickly boil water to meet the boiling water needs of different hot water, and in daily cleaning and maintenance work, it is only necessary to remove the left end cover 11 and the adapter 3, the first heating tube 31 and the second heating tube 32 connected thereto from the inner tank 2, and the inner cavity of the inner tank 2 can be directly cleaned and maintained. At this time, the sleeve 4 is in a state of opening to the left side so that its inner cavity space is connected with the inner cavity space of the inner tank 2, so the inner cavity of the sleeve 4 can be directly cleaned and maintained, and there is no need to further disassemble the inner tank 2 and the sleeve 4, thereby improving the processing efficiency of the cleaning and maintenance work of the inner tank 2 and the sleeve 4.

[0033] The conventional water-boiling mode of a household multifunctional water-boiling device of the present invention has the following working steps: the four-way electric-controlled valve 23 is initially in a closed state, the three-way electric-controlled valve 33 is initially in a state where the water inlet port is connected to the first water outlet port and the second water outlet port, the water inlet pipe 21 is externally connected to a water supply pipe, and the water outlet pipe 22 is externally connected to a water discharge pipe, the external water supply pipe continuously transports water into the inner tank 2 through the water inlet pipe 21, and the first heating pipe 31 and the second heating pipe 32 synchronously heat the water entering the inner tank 2. In this process, the water output from the water inlet pipe 21 is heated. After flowing through the diversion channel 301 of the adapter 3, the water is directly ejected outward through the first channel 302 and the second channel 303 to between the first heating tube 31 and the second heating tube 32, so that the ejected water flow directly contacts the first heating tube 31 and the second heating tube 32 to quickly complete the heating treatment, and the heated water flow quickly diffuses to various areas in the inner tank 2. At the same time, the first temperature sensor 13 monitors the hot water temperature in the inner tank 2, so that a large amount of hot water is obtained in the inner tank 2, meeting the water boiling demand of obtaining a large amount of hot water with only one boiling operation.

[0034] When the hot water in the inner tank 2 is needed, the four-way electric control valve 23 is switched to a state where the first water inlet port and the water outlet port are connected, allowing the hot water in the inner tank 2 to flow out to the external drain pipe through the outlet pipe 22, thereby continuously draining a large amount of hot water. At this time, the first heating tube 31 and the second heating tube 32 are both in a stopped working state.

[0035] The working steps of the fast water boiling mode of a household multifunctional water boiling device of the present invention are as follows. When a small amount of hot water is needed quickly, the motor 53 drives the screw rod 52 to rotate, and the screw rod 52 drives the sleeve 4 to move leftward along the limit rod 51 until it is close to the adapter 3, so that the first heating tube 31 and the second heating tube 32 enter the first inner cavity 401 and the second inner cavity 402 of the sleeve 4 respectively. At this time, the first inner cavity 401 and the second inner cavity 402 of the sleeve 4 and the adapter 3 form two independent closed small spaces respectively. Subsequently, according to the above steps, the external water supply pipe continuously transports water to the diversion channel 301 of the adapter 3 through the water inlet pipe 21, and the water flows through the first inner cavity 401 and the second inner cavity 402 of the sleeve 4. The first channel 302 and the second channel 303 spray water into the first inner cavity 401 and the second inner cavity 402 of the sleeve 4 respectively. At the same time, the first heating tube 31 and the second heating tube 32 quickly complete the water heating process in the first inner cavity 401 and the second inner cavity 402 of the sleeve 4, which are two independent closed small spaces. At the same time, the second temperature sensor 44 and the third temperature sensor 45 respectively monitor the hot water temperature in the first inner cavity 401 and the second inner cavity 402 of the sleeve 4, so as to quickly obtain two portions of hot water in the first inner cavity 401 and the second inner cavity 402 respectively, thereby meeting the demand for quickly obtaining hot water by waiting for a short period of time.

[0036] When the hot water in the sleeve 4 is needed, the three-way electric control valve 33 is first switched to a state where the water inlet port is not connected to the first water outlet port and the second water outlet port, so that the water flow in the external water supply pipe no longer flows to the sleeve 4, and then the four-way electric control valve 23 is switched to a state where the second water inlet port is connected to the water outlet port, so that the hot water in the first inner cavity 401 of the sleeve 4 flows out to the external drain pipe through the first water conduit 24 and the water outlet pipe 22 in turn, and the hot water is drained quickly. At this time, the first heating tube 31 and the second heating tube 32 are both in a stopped working state. When the hot water in the first inner cavity 401 of the sleeve 4 is about to be drained, the four-way electric control valve 23 is first switched to a state where the third water inlet port is connected to the water outlet port. In the open state, the hot water in the first inner cavity 401 of the sleeve 4 is no longer discharged, and the hot water in the second inner cavity 402 of the sleeve 4 flows out to the external drain pipe through the first water conduit 24 and the water outlet pipe 22 in turn, and the hot water draining work continues to be performed quickly. The three-way electric control valve 33 is then switched to a state where the water inlet port is only connected to the first water outlet port, so that the water flow in the external water supply pipe only flows into the first inner cavity 401 of the sleeve 4. At the same time, the first heating tube 31 quickly heats the hot water in the first inner cavity 401 of the sleeve 4 again, and in this way, the hot water heating treatment and the corresponding hot water draining work are alternately and quickly completed in the first inner cavity 401 and the second inner cavity 402 of the sleeve 4.

[0037] In addition, in a household multifunctional water-boiling device of the present invention, the first heating tube 31 and the second heating tube 32 are used as heating components for water-boiling, and both use an insulating substrate layer as a substrate, a titanium diboride semiconductor coating layer is combined on the insulating substrate layer, and then an anti-oxidation and insulating protective film layer is combined outside the titanium diboride semiconductor coating layer. The anti-oxidation and insulating protective film layer can play an antioxidant and insulating protective role on the titanium diboride semiconductor coating layer, thereby ensuring the safety of electricity use; and the titanium diboride semiconductor coating layer itself has semiconductor properties, and when the heating temperature reaches a certain value, the energy consumption will be reduced, which greatly saves electric energy and has better energy efficiency performance, and the titanium diboride semiconductor coating layer can achieve rapid heating and quickly increase the temperature to achieve efficient heating; in addition, the insulating substrate layer and the titanium diboride semiconductor coating layer with similar thermal expansion coefficients are combined, so that the two will not cause cracking due to inconsistent thermal expansion coefficients, and it has better reliability and durability.

[0038] Since the titanium diboride semiconductor coating layer used in the first heating tube 31 and the second heating tube 32 has high thermal conductivity and stability, it can transfer heat to water more quickly while reducing heat loss. Whether in the conventional water boiling mode or the fast water boiling mode, the water boiling energy efficiency can be improved, and the required hot water can be obtained in a short time, the waiting time can be reduced, and the power consumption of water boiling can be reduced. At the same time, the titanium diboride semiconductor coating layer has high temperature resistance and corrosion resistance, which reduces the safety hazards in the heating process. The household multifunctional water boiling device of the present invention has the three characteristics of high efficiency, energy saving and safety, while improving the user's experience of fast water boiling, it meets the safety of water boiling work.

[0039] In daily cleaning and maintenance of a household multifunctional water-boiling device of the present invention, since the inner tank 2 and the sleeve 4 can be directly cleaned and maintained, not only the complexity of disassembly is reduced, the risk of damage to the inner tank 2 and the sleeve 4 is reduced, and the durability of the device is improved, but also the titanium diboride semiconductor coating layer used in the first heating tube 31 and the second heating tube 32 can reduce the scaling rate by 60% compared with direct metal contact during the heat generation and water heating process, which greatly reduces the difficulty of daily cleaning and maintenance of the household multifunctional water-boiling device of the present invention.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1-Figure 7 As shown, two fixing rods 42 are fixedly connected to the right end cover 12 of the present embodiment; the two fixing rods 42 are both slidably connected to the sleeve 4, and the two fixing rods 42 are respectively located in the first inner cavity 401 and the second inner cavity 402 of the sleeve 4; a water baffle 43 is slidably connected in the first inner cavity 401 of the sleeve 4; a water baffle 43 is also slidably connected in the second inner cavity 402 of the sleeve 4; the two water baffles 43 are made of insulation board material; the two fixing rods 42 are respectively fixedly connected to the corresponding water baffles 43; a water through hole 4301 structure is respectively provided on the two water baffles 43, and the water flow in the first inner cavity 401 and the second inner cavity 402 of the sleeve 4 can contact the second temperature sensor 44 and the third temperature sensor 45 respectively more quickly after passing through the water through hole 4301.

[0042] In a conventional water boiling mode, a household multifunctional water boiling device of the present invention sprays water to the right from the first channel 302 and the second channel 303 of the adapter 3 after being heated by the first heating tube 31 and the second heating tube 32. When the water continues to flow to the right, it will be intercepted by the water baffle 43 made of the insulation board material and will not directly enter the sleeve 4. After being intercepted by the water baffle 43, the heated water will quickly diffuse in all directions of the inner tank 2, thereby improving the thermal diffusion efficiency of the water flow in the inner tank 2 and increasing the water boiling speed.

[0043] In the fast water boiling mode of a household multifunctional water boiling device of the present invention, when the motor 53 controls the screw rod 52 to drive the sleeve 4 to move leftward and cover the adapter 3 according to the above steps, the two water baffles 43 are pulled by the fixing rod 42 and move to the right side in the sleeve, so that the first heating tube 31 and the second heating tube 32 are not blocked by the water baffle 43 and can smoothly enter the first inner cavity 401 and the second inner cavity 402 of the sleeve 4 respectively.

[0044] Example 3

[0045] On the basis of Example 1, Figure 1-Figure 8 As shown, a guide channel 4101 structure is provided in the partition plate 41 of the sleeve 4 of this embodiment; a plurality of water inlet holes 4102 structures connected to the first inner cavity 401 are provided on the partition plate 41 of the sleeve 4; the water inlet holes 4102 are connected to the guide channel 4101; all the water inlet holes 4102 are located on the partition plate 41 on the side away from the first channel 302; a plurality of water outlet holes 4103 structures connected to the second inner cavity 402 are provided on the partition plate 41 of the sleeve 4; the water outlet holes 4103 are connected to the guide channel 4101; all the water outlet holes 4103 are located on the partition plate 41 on the side close to the second channel 303; a block 46 is slidably connected in the guide channel 4101 of the partition plate 41, and the block 46 blocks all the water inlet holes 4102; an electric control push rod 47 is installed in the partition plate 41; the telescopic end of the electric control push rod 47 is fixedly connected to the block 46.

[0046] The working steps of switching a household multifunctional water-boiling device to a continuous water-boiling mode of the present invention are as follows: first, the motor 53 controls the screw rod 52 according to the above steps to drive the sleeve 4 to cover the adapter 3, so that the first heating tube 31 and the second heating tube 32 enter the first inner cavity 401 and the second inner cavity 402 of the sleeve 4 respectively, and at the same time, the three-way electric control valve 33 is switched to a state of being connected to the water inlet pipe 21 and the first channel 302 of the adapter 3 respectively, and at the same time, the electric control push rod 47 pulls the block 46 to leave the water inlet hole 4102 of the partition plate 41, and at the same time, the four-way electric control valve 23 is switched to a state of being connected to the water outlet pipe 22 and the second water guide pipe 25 respectively, so that the water flows through the water inlet pipe 21 and the first channel 302 of the adapter 3 into the first inner cavity 401 of the sleeve 4, and then the water flows through the partitions successively. The water inlet hole 4102, the guide channel 4101 and the water outlet hole 4103 of the plate 41 then flow through the second inner cavity 402 and the second water guide pipe 25 of the sleeve 4 in sequence and flow out from the water outlet pipe 22. During this process, the water will flow through the first heating tube 31 and the second heating tube 32 in sequence for two heating operations, so that the water can be continuously heated without stopping. Compared with the fast water boiling mode, which requires waiting for a specified time to heat the water to a specified temperature, the heating time of the water in the continuous water boiling mode is shorter. Therefore, the hot water heating temperature in the continuous water boiling mode will be lower than the hot water heating temperature in the fast water boiling mode. However, at the same time, the continuous water boiling mode can continuously provide heated hot water, which meets the water boiling demand of not requiring the hot water temperature to be too high but being able to provide hot water continuously and quickly.

[0047] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
