Description

Technical Field

[0001] This utility model relates to the field of electric water heater technology, and more specifically, to an electric water heater that facilitates thermostat reset. Background Technology

[0002] An electric water heater is a device used to heat water. Currently, Chinese Patent Publication No. CN223424728U discloses an overheat protection structure for an electric water faucet. In this electric water faucet structure, a slot is provided at the upper end of the heat-conducting component, and the heating part of the electric heating tube is inserted into the slot and attached to the inner wall of the slot. That is, the heat-conducting component and the electric heating tube can achieve the purpose of contact heat conduction without welding. This can facilitate the assembly of the heat-conducting component and the electric heating tube, reduce production costs, and avoid shortening the service life of the electric heating tube due to the high temperature of welding, since the heat-conducting component does not need to be welded to the electric heating tube. Furthermore, because the heating element of the electric heating tube is partially inserted into the slot and adheres to the inner wall of the slot, the contact area between the electric heating tube and the heat-conducting component is increased. This allows the heat-conducting component to better transfer the heat from the electric heating tube to the temperature-sensing end of the resettable thermostat. During use, when the electric water faucet activates its overheat protection, the thermostat will remain in an open-circuit state. Since the thermostat is located inside the electric water faucet, the user cannot reset it externally. This means that after the electric water faucet triggers its overheat protection, it needs to be returned to the factory to reset its internal thermostat, which will cause inconvenience to the user. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electric water heater with an easy thermostat reset. After the internal thermostat is activated for overheat protection, the user can reset the thermostat himself, which makes the thermostat reset convenient and thus makes it easier for the user to use.

[0004] This utility model provides an electric water heater with an easy thermostat reset, including a shell assembly, an inner tank assembly, an electric heating element, and a manually resettable thermostat. The shell assembly is wrapped around the outside of the inner tank assembly. The electric heating element is installed in the heating chamber of the inner tank assembly. The thermostat is fixed to the lower end of the inner tank assembly, and the temperature measuring end of the thermostat contacts a heat-conducting element located at the bottom of the inner tank assembly for heat conduction. The electric water heater also includes a push rod. The push rod is vertically slidably connected to the inside of the shell assembly. The upper end of the push rod is in clearance fit with the reset button of the thermostat, and the lower end of the push rod abuts against the inner bottom of the shell assembly. A through hole is vertically provided at the bottom of the shell assembly. When the pusher passes through the through hole and pushes the push rod upward, the push rod is used to push the reset button of the thermostat to reset the thermostat.

[0005] With the above-described structure, when the thermostat in the electric water heater activates overheat protection, the user can hold the pusher and push it through the through hole to push the push rod upwards. At this time, the push rod can push the reset button of the thermostat to reset the thermostat, thus making it easier to reset the thermostat and thus making it more convenient for the user.

[0006] The through hole is coaxial with the push rod, and the diameter of the through hole is smaller than the outer diameter of the push rod.

[0007] A clamping element is fixed on the bottom of the inner liner assembly. The thermostat is pressed against the lower end of the inner liner assembly by the clamping element. A sliding hole is vertically provided on the clamping element. The reset button of the thermostat extends into the upper end of the sliding hole, and the upper end of the push rod moves through the sliding hole.

[0008] An annular conical surface is provided on the outer wall of the upper end of the push rod. The annular conical surface is used to cooperate with the inner wall of the sliding hole for guidance so that the upper end of the push rod can be inserted into the sliding hole.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0013] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] See Figures 1-4 As shown in the figure, this application discloses an electric water heater that facilitates thermostat reset, including a shell assembly 1, an inner tank assembly 2, an electric heating tube 3, and a manually resettable thermostat 4; the shell assembly 1 is wrapped around the outside of the inner tank assembly 2, the electric heating tube 3 is installed in the heating chamber 21 of the inner tank assembly 2, the thermostat 4 is fixed at the lower end of the inner tank assembly 2, and the temperature measuring end of the thermostat 4 is in contact with the heat-conducting element 5 located at the bottom of the inner tank assembly 2 for heat conduction; the electric water heater also includes a push rod 6; the push rod 6 is vertically slidably connected to the inside of the shell assembly 1, the upper end of the push rod 6 is clearance-fitted with the reset button 41 of the thermostat 4, and the lower end of the push rod 6 abuts against the inner bottom of the shell assembly 1, and a through hole 11 is vertically provided at the bottom of the shell assembly 1; when the pusher passes through the through hole 11 and pushes the push rod 6 upward, the push rod 6 is used to push the reset button 41 of the thermostat 4 to reset the thermostat 4.

[0015] The through hole 11 is coaxially arranged with the push rod 6, and the diameter of the through hole 11 is smaller than the outer diameter of the push rod 6. With this structure, since the through hole and the push rod are coaxially arranged, when the pusher passes through the through hole and pushes the push rod upward, the pusher can more reliably push the push rod to move the push rod upward, that is, the push rod can reliably push the reset button of the thermostat to reset the thermostat. Since the diameter of the through hole is smaller than the outer diameter of the push rod, the push rod can be prevented from falling out of the housing assembly through the through hole. That is, under normal conditions, the lower end of the push rod can reliably abut against the inner bottom of the housing assembly.

[0016] A clamping member 7 is fixed on the bottom of the inner liner assembly 2. The thermostat 4 is clamped to the lower end of the inner liner assembly 2 by the clamping member 7. A sliding hole 71 is vertically provided on the clamping member 7. The reset button 41 of the thermostat 4 extends into the upper end of the sliding hole 71, and the upper end of the push rod 6 is movably inserted into the sliding hole 71. Through the setting of the clamping member, the thermostat can be reliably clamped to the lower end of the inner liner assembly. And because the clamping member is vertically provided with a sliding hole, the reset button of the thermostat extends into the upper end of the sliding hole, and the upper end of the push rod is movably inserted into the sliding hole. Thus, when the push rod is pushed, the sliding hole can limit and guide the movement of the push rod, so that the push rod can more reliably push the reset button of the thermostat to reset the thermostat.

[0017] An annular conical surface 61 is provided on the outer wall of the upper end of the push rod 6. The annular conical surface 61 is used to cooperate with the inner wall of the sliding hole 71 for guidance so that the upper end of the push rod 6 can be inserted into the sliding hole 71. With this structure, when assembling the electric water heater, the annular conical surface can cooperate with the inner wall of the sliding hole for guidance so that the upper end of the push rod can be inserted into the sliding hole, which can facilitate the assembly of the electric water heater.

[0018] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
