Description

instant hot electric kettle

technical field

The utility model relates to an instant heating type fast electric kettle.

Background technique

The existing electric kettle includes a water tank, an electric heating tube, and a temperature controller. The heat directly heats the cold water in the entire water tank to the set value of the thermostat, and the thermostat acts to disconnect the power supply. When using hot water, lift the entire kettle and pour it into the cup for use until the hot water is used up. Inject cold water repeatedly and use it for heating, and if the hot water in the water tank is not used up in time after one heating, the hot water stored in the water tank will automatically cool down after a period of time, wasting electric energy; The volume of the water tank of the kettle should neither be too small nor too large, because if the volume of the water tank is too small, when the water consumption is large, the work of adding water must be carried out frequently, which is inconvenient to use; if the volume of the water tank is too large, not only the heating (waiting) It takes a long time, and when the water consumption is small, the hot water remaining in the water tank is naturally cooled after each heating, resulting in a waste of electric energy; of course, the user can determine the amount of cold water injected into the water tank according to the amount of hot water each time, but generally Under the circumstances, the user is difficult to accurately judge the amount of hot water used each time, either the hot water is not enough or there is too much, so the existing electric kettle is inconvenient to use.

Contents of the invention

The purpose of the utility model is to solve the problems of long heating time and convenient water use of the existing electric kettles, and provide an instant heating electric kettle with fast heating, convenient use and simple structure.

The purpose of this utility model is achieved in this way: an instant hot electric kettle, including a shell, a cold water tank and a hot water tank, is characterized in that the bottom of the hot water tank is provided with an electric heating tube, above the hot water tank There is a cold water tank, and the channel between the hot water tank and the cold water tank is provided with a one-way valve to control the flow of water from the cold water tank to the hot water tank. The water injection port of the cold water tank is exposed outside the shell, and the hot water The tank is provided with a water outlet pipe protruding out of the shell and the water outlet is higher than the position of the one-way valve, and the outer end of the control rod of the thermostat of the hot water tank protrudes out of the shell. When in use, fill cold water through the water outlet of the cold water tank, put a water cup smaller than the volume of the hot water tank under the water outlet of the water outlet, and turn on the power, because the volume of the hot water tank is as small as 200mL, so the water in the hot water tank The water temperature rises rapidly, during which the volume expands, and the hot water in the hot water tank flows out through the water outlet of the water outlet pipe and falls into the water cup (because the cold water in the hot water tank has not been heated during the first use, the first It is best not to drink the second cup of water), until the temperature of the water in the hot water tank rises to the set value of the thermostat, and then the water outlet pipe stops flowing, and the hot water in the water cup can be drunk, while the remaining water in the hot water tank During the cooling process of water, because the water temperature in the hot water tank drops, the volume of the hot water shrinks, and the cold water in the cold water tank replenishes cold water to the hot water tank through the one-way valve. Below the water outlet of the water pipe, manually control the thermostat to reset the temperature control, and the electric heating tube heats the water in the hot water tank again to repeat the above-mentioned flowing out process of hot water.

The passage between the hot water tank and the cold water tank is in a vertical direction, and the floating ball located in the passage and the passage form the one-way valve.

A limiting ring is arranged in the channel, and the limiting ring and the floating ball constitute the one-way valve.

The thermostat is a manual reset thermostat.

Due to the adoption of the technical solution described in the utility model, the volume of the hot water tank is much smaller than that of the cold water tank, and only a small amount of water is heated for the hot water tank. , it will not cause waste of electric energy due to the large amount of hot water heated at one time; the cold water tank is large in size, and can be connected to the hot water tank to supply water when the heating is stopped, and there is no need to frequently fill the electric kettle with cold water, saving workload and using convenient.

Detailed ways:

As shown in Fig. 1, the instant hot-type fast electric kettle includes a shell made of a base 22 and a face shell 21, a cold water tank 1 and a hot water tank made of a hot water tank seat 3 and a hot water tank cover 4. The lower side of the hot water tank seat 3 made of stainless steel is brazed with an electric heating tube 31. The electric heating tube 31 is connected in series with the manual reset thermostat 32 and then connected to the mains power supply. The outer end of the manual reset control rod 33 of the thermostat 32 extends out of the face shell 21 outside the left end, the hot water tank cover 4 and the hot water tank seat 3 are sealed to form a hot water tank, and the upper side of the hot water tank cover 4 is respectively provided with a hot water connector 42 and a cold water connector 41, wherein the hot water connector 42 It is connected to the water inlet at the lower end of the water outlet pipe 5 through a connecting piece 52 .

2, the cold water connector 41 is connected to the lower end of the cold water pipe 61 through a connector 62, wherein a limit ring 63 is fixed in the cold water pipe 61, and the limit ring 63 and the floating ball 64 constitute a one-way valve.

See Fig. 1, when in use, open the cold water tank cover 11, fill cold water in the cold water tank 1, switch on the power supply, the electric heating tube 31 heats the water in the hot water tank, because the power of the electric heating tube is large enough, the water in the hot water tank Due to the use of the one-way valve formed by the floating ball 64 and the limit ring 63, the hot water can only enter through the water inlet 51 of the water outlet pipe 5 and then flow out through the water outlet 53 and fall into the water cup 54. The volume of the water cup is large enough so that the amount of water flowing out of the hot water tank will not exceed the capacity of the water cup. When the water temperature in the hot water tank reaches the operating temperature of the thermostat 32, the thermostat acts to cut off the power supply of the electric heating tube 31, and the hot water The water temperature in the tank no longer rises, and then the water outlet of the water outlet pipe stops flowing water. When the water temperature in the hot water tank drops, the cold water in the cold water tank overcomes the buoyancy of the floating ball 64 and flows into the hot water tank. When hot water is needed again, The position outside the face shell 21 can be pressed by the left end of the control rod 33 by hand, so that the thermostat 32 is reset and the hot water in the hot water tank is heated again, and the above process is repeated.

The connecting piece 52 and the hot water connecting head 42 may be threaded, and the connecting piece 62 and the cold water connecting head 41 may also be screwed.
