Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a storage type electric water heater. Background Art

[0002] A water heater refers to a device that can heat cold water to hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc. The existing storage type electric water heater allows cold water to flow into the inner tank from the water inlet, and then the cold water is heated by a heating pipe and flows out from the water outlet.

[0003] According to the publication number: CN220206054, it is specifically a storage type electric water heater, including a housing. A heat preservation layer is installed inside the housing, an inner tank is installed inside the heat preservation layer, a flange is installed on the right surface of the inner tank, a temperature probe tube is installed on the left surface of the flange, an electric heating rod is arranged at the bottom of the temperature probe tube, a sewage outlet is opened on the left inner wall at the bottom of the inner tank, a magnesium rod is installed on the top surface of the sewage outlet, and a water outlet pipe is installed on the middle side inner wall at the bottom of the inner tank. By turning on the power switch, the cold water flows into the inner tank from the water inlet pipe. Under the heating effect of the electric heating rod, the cold water becomes hot water, and gradually forms a stratification of cold water and hot water. Since the height of the water inlet pipe is much lower than that of the water outlet pipe, the hot water output rate of the electric water heater is greatly increased, and the energy consumption of the storage type electric water heater is reduced. Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that although the above equipment can solve the problem that the cold water flowing into the inner tank from the water inlet will impact the hot water layer and cause the stratification of cold water and hot water to be damaged when applied.

[0004] In order to ensure the constant pressure inside the equipment, a safety valve is usually installed at the water inlet. However, after a long time of operation, the sealing parts of the safety valve may lose their original effectiveness due to aging, resulting in leakage. In addition, impurities inside the equipment accumulate on the sealing surface or the valve core of the safety valve, blocking the valve and causing water leakage. Since the above equipment lacks a water leakage detection function, the leakage will not be detected in time, resulting in a continuous decrease in the pressure inside the equipment and being unable to maintain within the necessary working range, thereby affecting the normal operation of the equipment.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 3 shown, a storage-type electric water heater provided by the present utility model includes an electric water heater body 1, a safety valve 2, a water inlet pipe 3 and a water outlet pipe 4. The water inlet pipe 3 is connected to the right side of the bottom of the electric water heater body 1, the water outlet pipe 4 is connected to the left side of the bottom of the electric water heater body 1, the safety valve 2 is connected to the right side of the surface of the water outlet pipe 4, the right side of the bottom of the electric water heater body 1 is fixedly connected with a water storage box 5, the safety valve 2 is located inside the water storage box 5, the bottom of the water storage box 5 is communicated with a water storage cylinder 6, a liquid level sensor 7 is fixedly installed at the bottom of the water storage cylinder 6, and the right side of the back of the water storage box 5 is fixedly connected with a reminder component 8.

[0023] Refer to Figure 2 andFigure 3 , the reminder component 8 includes a controller 81, the controller 81 is fixedly connected to the right side of the back surface of the water storage box 5, a buzzer 82 is fixedly connected to the left side of the back surface of the water storage box 5, and the controller 81 is electrically connected to the liquid level sensor 7 and the buzzer 82 through wires respectively.

[0024] As a technical optimization scheme of the present utility model, by setting the reminder component 8, the liquid level sensor 7 transmits the detection data to the inside of the controller 81 in real time through a wire. The controller 81 analyzes the detection data. When the analysis result indicates the presence of water, the controller 81 activates the buzzer 82, so that the buzzer 82 emits a beeping sound to remind the operator of a water leakage situation and prevent the operator from failing to detect the water leakage of the safety valve 2 in time.

[0025] Reference Figure 2 and Figure 3 , a waterproof box 9 is fixedly connected to the back surface of the water storage box 5, and the controller 81 and the buzzer 82 are located inside the waterproof box 9.

[0026] As a technical optimization scheme of the present utility model, by setting the waterproof box 9, the waterproof box 9 is fixedly installed with the water storage box 5, so that the waterproof box 9 plays a protective role in the use of the controller 81 and the buzzer 82, and prevents the controller 81 and the buzzer 82 from being damaged by water ingress.

[0027] Reference Figure 2 and Figure 3 , a sound-emitting hole 10 is opened at the bottom of the waterproof box 9, and a plurality of sound-emitting holes 10 are provided and are evenly distributed in a rectangular shape.

[0028] As a technical optimization scheme of the present utility model, by setting the sound-emitting hole 10, the beeping sound can penetrate to the outside of the waterproof box 9 through the sound-emitting hole 10, preventing the waterproof box 9 from blocking the transmission of the beeping sound.

[0029] Reference Figure 2 and Figure 3 , a maintenance door 11 is movably connected to the front side inside the water storage box 5 through a hinge.

[0030] As a technical optimization scheme of the present utility model, by setting the maintenance door 11, the maintenance door 11 is movably installed with the water storage box 5 through a hinge. When the operator needs to replace the leaking safety valve 2, the operator can enter the inside of the water storage box 5 by opening the maintenance door 11, thus ensuring the convenience of the operator to replace the safety valve 2.

[0031] Reference Figure 2 and Figure 3 , a plurality of air outlet holes 12 are opened at the rear side of the inner wall of the water storage box 5, and the air outlet holes 12 are evenly distributed in a rectangular shape.

[0032] As a technical optimization solution of the present utility model, by providing an air outlet 12, when the safety valve 2 discharges the air inside the electric water heater body 1, the discharged air can be discharged through the air outlet 12, avoiding the situation that the water storage box 5 forms an airtight space and the gas cannot be discharged.

[0033] Reference Figure 2 and Figure 3 , the water storage cylinder 6 is arranged in a trumpet shape with a larger upper part and a smaller lower part.

[0034] As a technical optimization solution of the present utility model, by providing a water storage cylinder 6 with a larger upper part and a smaller lower part, the water leaked from the safety valve 2 can accurately fall on the bottom of the water storage cylinder 6, that is, the detection position of the liquid level sensor 7, thus ensuring the timeliness of the liquid level sensor 7 to detect water leakage.

[0035] The working principle and usage process of the present utility model: During use, first fixedly install the water storage box 5 on the electric water heater body 1, then connect the water storage cylinder 6 with the water storage box 5, then install the liquid level sensor 7 at the bottom of the water storage cylinder 6, and then electrically connect the liquid level sensor 7 to the controller 81 through a wire. When the safety valve 2 leaks water, the dripping water will enter the water storage cylinder 6 through the water storage box. At the same time, the liquid level sensor 7 in the water storage cylinder 6 will transmit the detection data to the controller 81. The controller 81 analyzes the detection data. When the analysis result indicates the presence of water, the controller 81 activates the buzzer 82, so that the buzzer 82 emits a beeping sound to remind the operator of the water leakage situation and avoid the operator being unable to timely detect the water leakage of the safety valve 2.

[0036] In summary: For this storage-type electric water heater, by providing a water storage box 5, a water storage cylinder 6 and a liquid level sensor 7, when the safety valve 2 leaks, the leaked water will drip into the water storage cylinder 6 through the water storage box. The liquid level sensor 7 inside the water storage cylinder 6 detects the leaked water and transmits the detection data to the reminder component 8, so that the reminder component 8 emits a sound to remind the operator, avoiding the operator being unable to timely detect the water leakage of the safety valve 2 and solving the problem that due to the lack of a water leakage detection function in the above equipment, the leakage cannot be timely detected, resulting in a continuous decrease in the pressure inside the equipment and being unable to maintain within the necessary working range, thereby affecting the normal operation of the equipment.
