Description

Technical Field

[0001] The invention relates to the technical field of hot water kettles, and in particular to a silent instant hot water kettle and a use method thereof. Background Art

[0002] Traditional household electric kettles produce huge noise during the heating process, which is a serious problem for those who are sensitive to noise and families with children and the elderly. The reasons for the noise of traditional electric kettles are as follows: 1. Heating will cause the air in the water to precipitate and form bubbles. The bursting of bubbles is the main reason for the noise of traditional household electric kettles; 2. The commonly used electric kettles on the market use a resistive heating base. Because the bottom of the kettle is heated unevenly, it will cause convection of hot and cold water and cause violent vibration of the kettle body; 3. Generally, when users add water, electric kettles will reserve space to prevent overfilling and heating overflow. Therefore, during the heating process, a large amount of water vapor will be generated in the cavity of the kettle body to generate gas turbulence, which will cause the kettle body to vibrate, and the existence of the cavity will amplify the noise of bubble bursting; 4. The current structure of traditional household electric kettles mainly uses 304 stainless steel inner tanks and external thermal insulation materials, but the noise problem is not taken into consideration because no sound insulation materials are added to the outside of the kettle body.

[0003] In addition to the noise, another important problem of traditional household electric kettles is the slow heating speed and low efficiency. The instant electric kettle effectively solves this problem, but there are still a series of problems, such as: 1. The instant electric kettle adopts monocrystalline silicon heating technology, and the power of the product is generally 2200w. It only takes 1.93s to make the water boil. However, due to the new heating method, the amount of water heated per unit time is limited and the water volume is low, which cannot meet the large demand for boiling water in certain occasions. This directly affects the scope of use of the instant electric kettle. The power of traditional kettles is generally 80w, and it takes more than 5 minutes to boil water for an electric kettle with a power of 1500w. Therefore, compared with traditional kettles, although the instant electric kettle solves the problem of boiling time, it reduces the water output, and consumes more power than traditional kettles, which does not meet the requirements of energy saving and environmental protection of household electronic products in my country.

[0004] Another issue that needs attention is that the heating of water will cause different boiling points due to the different altitudes and air pressures in different regions. In high altitude areas, water can only be heated by increasing the pressure, which directly limits the scope of use of traditional electric kettles. Summary of the invention

[0005] The object of the present invention is to provide a silent instant hot water kettle and a use method thereof.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a silent instant hot water kettle, comprising a water tank, a heating rod and an inner liner in a tubular shape and spirally arranged around the heating rod, the head end of the inner liner is connected to the water tank, the tail end of the inner liner is connected to the water outlet, and a first control valve is provided at the connection between the inner liner and the water tank, and a second control valve is provided at the connection between the inner liner and the water outlet;

[0007] It also includes a reset energy absorption system, which includes a cylinder body connected to the inner tank, a piston block matched with the sliding guide is arranged in the cylinder body, and the piston block is connected to the guide reset device.

[0008] The invention also comprises a casing, a heating rod, an inner container and a self-resetting energy absorption system are all arranged in the casing, and a water tank is arranged outside the casing.

[0009] The casing comprises a vacuum heat-insulating layer and a sound-insulating layer arranged from the inside to the outside.

[0010] The heating rod is arranged vertically, the head end of the inner tank is located at the bottom of the casing, and the head end of the inner tank is connected to the bottom of the water tank to form a communicating vessel; the connection position between the cylinder and the inner tank in the reset energy absorption system is set close to the head end of the inner tank.

[0011] A water level control sensor is installed in the water tank.

[0012] The guide reset device is a spring reset structure or a hydraulic rod structure.

[0013] The heating rod is a hollow structure, the reset energy absorption system is arranged in the hollow cavity of the heating rod, and the heating rod and the reset energy absorption system in the hollow cavity cooperate to form a heating core.

[0014] The heating rod is detachably installed in the casing.

[0015] The present invention further comprises a control switch arranged on the casing, and the control switch is control-connected with the first control valve and the second control valve.

[0016] The present invention also discloses a method for using a silent instant heating kettle, comprising the following steps:

[0017] 1) The first control valve is opened, and the water tank fills water into the inner tank; after the inner tank is filled with water, the first control valve and the second control valve are controlled to close;

[0018] 2) Start the heating rod to start heating. During the heating process of the inner tank, air will be separated from the water. The heat expansion will increase the air pressure in the inner tank. At the same time, the water vapor will work on the piston block to move the piston block and drive the guide reset device to work. The thermal energy of the water vapor is converted into mechanical energy and stored in the guide reset device.

[0019] 3) After heating is completed, the second control valve is opened, and the guide reset device pushes the piston block to move in the opposite direction, pushing the hot water in the inner tank to move in the opposite direction and finally flowing out through the water outlet.

[0020] The beneficial effects of the present invention are:

[0021] The present invention can not only greatly reduce the noise problem during the heating process, but also, compared with the traditional instant electric kettle, can effectively reduce the heating time and reduce energy consumption without reducing the water output; compared with the traditional household electric kettle, it can effectively increase the heating area, shorten the heating time, and at the same time control the pressure in the kettle, so that the kettle can also be used in high-altitude areas.

DETAILED DESCRIPTION

[0025] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a silent instant hot water kettle of the present invention comprises a casing 17, a water tank 9, a heating rod 12 and an inner liner 5 which is tubular and spirally arranged around the heating rod. The inner liner 5 is a spiral 304 stainless steel inner liner.

[0027] The inner tank 5 is designed to be spiral and made of 304 stainless steel because 304 stainless steel is corrosion-resistant, has good plasticity, is non-magnetic or weakly magnetic, and is suitable for producing container-type tableware. The spiral inner tank changes the overall heating method of the traditional electric water heater into segmented heating, which changes the traditional bottom heating and produces uneven heating problems, greatly increases the heating area, and through the optimized design of the product, the heating area can be increased by at least 2 times, which can effectively shorten the heating time.

[0028] The casing 17 includes a vacuum insulation layer 7 and a sound insulation layer 6 arranged from the inside to the outside. The heating rod 12, the inner tank 5 and the self-resetting energy absorption system are all arranged in the casing 17. The water tank 9 is arranged outside the casing 17, and the casing 17 and the water tank 9 are both placed on the base 8.

[0029] The casing 17 can not only effectively reduce the noise generated during the heating process by providing the sound insulation layer 6 and the vacuum insulation layer 7, but also effectively maintain the temperature of the water in the inner tank, so that the unused hot water can be kept at a certain temperature for a long time to avoid secondary heating.

[0030] The head end of the inner tank 5 is connected to the water tank 9, the tail end of the inner tank 5 is connected to the water outlet 4, and a first control valve (electromagnetic check valve 11) is provided at the connection between the inner tank 5 and the water tank 9, and a second control valve (electromagnetic check valve 1) is provided at the connection between the inner tank 5 and the water outlet 4.

[0031] The present invention also includes a reset energy absorption system, which includes a cylinder 18 connected to the inner liner, and the connection position between the cylinder 18 and the inner liner 5 is arranged near the head end of the inner liner. A piston block 19 is arranged in the cylinder 18 to cooperate with the sliding guide, and the piston block 19 is connected to the guide reset device. The guide reset device can be a spring reset structure or a hydraulic rod structure. In this embodiment, the guide reset device is a hydraulic rod structure, which mainly includes a hydraulic rod 13 and a hydraulic cylinder 14.

[0032] In this embodiment, the heating rod is detachably installed in the casing 17, and the heating rod 12 is arranged vertically and is set as a hollow structure. The reset energy absorption system is set in the hollow cavity of the heating rod 12, and the heating rod and the reset energy absorption system in the cavity cooperate to form a heating core.

[0033] The head end of the inner tank 5 is located at the bottom of the housing 17, and the head end of the inner tank 5 is connected to the bottom of the water tank 9 to form a communicating vessel. By using the communicating vessel principle, the water level in the inner tank 5 is finally equal to the water level in the water tank 9. In addition, a water level control sensor is installed in the water tank 9, and when the water level in the inner tank reaches the target value, the electromagnetic check valve 11 and the electromagnetic check valve 1 are closed.

[0034] The present invention further comprises a control switch 2 and a control switch 3 arranged on the top of the housing 17, and the control switch 2 and the control switch 3 are control-connected with the first control valve and the second control valve.

[0035] This embodiment also discloses a method for using a silent instant hot water kettle, comprising the following steps:

[0036] 1) Add cold water to the water tank 9, and turn on the control switch 3, the electromagnetic check valve 11 is opened, and by using the connecting vessel principle, the water level in the inner tank 5 is finally equal to the water level in the water tank 9. When the water level in the inner tank 5 reaches the target value, the electromagnetic check valve 11 and the electromagnetic check valve 1 are closed;

[0037] 2) After the inner tank is filled with water, the resistance heating rod 12 is started to heat. Since the water contains air, the air will be separated from the water during the heating of the inner tank 5. The air expands due to the heat, causing the air pressure in the inner tank 5 to increase. Since the two electromagnetic check valves 1 and 11 are closed, the water vapor works on the piston block 19 to move the piston block 19. The movement of the piston block 19 further works on the hydraulic rod 13. The thermal energy of the water vapor is converted into mechanical energy and stored in the hydraulic rod structure. At the same time, the pressure in the inner tank 5 is reduced, and the water vapor disappears.

[0038] 3) After about 2 minutes, the temperature sensor senses that the water is boiling. At this time, the control switch 2 is pressed to open the electromagnetic check valve 1, and the hydraulic rod 13 is controlled to move in the opposite direction, pushing the hot water in the inner tank 5 to move in the opposite direction and finally flowing out through the water outlet 4.

[0039] Since the movement of the hydraulic rod 13 is controllable, water can be freely taken according to different needs; and by controlling the movement of the hydraulic rod 13, the pressure in the inner tank can be controlled, thereby ensuring that the pressure in the inner tank 5 is always maintained at 1 atmosphere, so that the kettle can also be used in high-altitude areas.

[0040] The above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
