Description

Technical Field

[0001] This utility model belongs to the field of electric water heater technology, specifically, it relates to a horizontal inner tank assembly and an electric water heater. Background Technology

[0002] Currently, water heaters are common household appliances. Electric water heaters can be divided into storage-type electric water heaters and instantaneous electric water heaters according to their heating power. Storage-type electric water heaters, due to their water tank configuration, have the advantages of large water output and stable water temperature, making them more popular among families. Existing storage-type electric water heaters typically have inlet and outlet pipes on the inner tank, and also include an electric heating element to meet heating requirements. In horizontal inner tanks, the inlet and outlet pipes are mostly installed vertically, resulting in lower heating efficiency and longer heating times. Furthermore, because the inner tank connects the inlet and outlet pipes to the heating element assembly, there is a risk of electric leakage.

[0003] Therefore, developing a horizontal inner tank assembly and electric water heater with high heating efficiency, shortened heating time, and reduced risk of electric leakage is an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a horizontal inner tank assembly and an electric water heater. The inner tank is placed horizontally, and cold water enters from the bottom inlet pipe, rises to the top after being heated, and flows out from the top outlet pipe, which improves heating efficiency, shortens heating time, and reduces the risk of water leakage into the electrical compartment.

[0005] To achieve the above-mentioned utility model / design objectives, the present utility model adopts the following technical solution:

[0006] In one respect, this application relates to a horizontal inner liner assembly.

[0007] An inner liner having an installation cavity formed therein, and a first installation position, a second installation position, and a third installation position having a communication with the installation cavity on the inner liner;

[0008] A heating tube assembly extends horizontally within the mounting cavity and is connected to the first mounting position;

[0009] A water inlet pipe assembly extends horizontally within the mounting cavity and is connected to the second mounting position;

[0010] A water outlet pipe assembly extends horizontally within the mounting cavity and is connected to the third mounting position;

[0011] The first mounting position is formed on the first side end of the inner liner in the horizontal direction, and the second and third mounting positions are formed on the second side end of the inner liner in the horizontal direction. When the horizontal inner liner assembly is in the installation direction, the water inlet pipe assembly, the heating pipe assembly, and the water outlet pipe assembly are arranged at intervals from low to high along the height direction.

[0012] In some embodiments of this application, the inlet pipe assembly and the outlet pipe assembly are installed symmetrically with respect to the axis of the inner liner.

[0013] In some embodiments of this application, the water outlet pipe assembly includes a horizontal extension section and a wall-hugging bend section. The first end of the horizontal extension section is connected to the third mounting position. The horizontal extension section extends horizontally. The second end of the horizontal extension section is connected to the wall-hugging bend section. The wall-hugging bend section bends toward the top wall of the mounting cavity.

[0014] In some embodiments of this application, the wall-mounted bending segment extends along an arc-shaped trajectory from the second end of the horizontal extension segment to the top wall near the mounting cavity.

[0015] In some embodiments of this application, a temperature measuring tube assembly is also included, which extends along the extension direction of the water outlet pipe assembly, and the temperature measuring tube assembly is disposed adjacent to the water outlet pipe assembly.

[0016] In some embodiments of this application, a fourth mounting position is formed on the inner liner, the temperature measuring tube assembly is inserted into the mounting cavity from the fourth mounting position, the temperature measuring tube assembly is connected to the fourth mounting position, and the fourth mounting position is formed at the first side end of the inner liner.

[0017] In some embodiments of this application, a flange and fastening assembly are also included, the flange being fitted at the first mounting position;

[0018] The heating tube assembly includes a heating tube and a heating tube flange base. One end of the heating tube is connected to the heating tube flange base, and the other end of the heating tube extends toward the second side end of the inner liner. The heating tube flange base is installed at the first mounting position and connected to the flange via the fastening assembly.

[0019] In some embodiments of this application, the heating tube assembly extends into the lower part of the mounting cavity.

[0020] In some embodiments of this application, a sealing component is also included, which is clamped between the heating tube flange base and the flange.

[0021] On the other hand, this application also relates to an electric water heater, including the horizontal inner tank assembly described in any of the preceding claims.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are:

[0023] By forming a first mounting position at the first side end of the inner tank, and forming a second mounting position and a third mounting position at the second side end on the opposite side of the inner tank, the heating tube assembly is installed horizontally from the first mounting position into the mounting cavity, the water inlet pipe assembly is installed horizontally from the second mounting position into the mounting cavity, and the water outlet pipe assembly is installed horizontally from the third mounting position into the mounting cavity. This allows the heating tube assembly, the water inlet pipe assembly, and the water outlet pipe assembly to be located on both sides of the inner tank in the horizontal direction, thereby avoiding leakage problems in the heating tube assembly in the event of leakage in the water inlet pipe assembly or the water outlet pipe assembly, and avoiding installation accidents.

[0024] By arranging the outlet pipe assembly, heating pipe assembly, and inlet pipe assembly vertically from high to low in the horizontal inner tank assembly, the distribution of cold and hot water in the installation cavity is conformed to the natural distribution of cold and hot water in the installation cavity. This avoids disrupting the distribution of cold and hot water in the installation cavity, thereby improving the hot water output rate, accelerating the circulation of cold and hot water, and reducing heat loss.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0063] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0064] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0065] In some embodiments of this application, an electric water heater is disclosed. An electric water heater uses electricity as its primary energy source; the high-temperature heat generated after power is applied directly heats the water stored within the water heater to produce hot water.

[0066] Electric water heaters typically consist of a water tank, an electric heating element, and an electronic control board. The water tank has a storage cavity to store water to be heated. The electric heating element is inserted into the storage cavity of the water tank. The electronic control board is used to control the electric heating element to operate by turning the power on and off, so that the water in the tank is heated to the set temperature.

[0067] For the water tank of an electric water heater, the tank generally consists of an outer shell and an inner tank 100, with an insulation layer between them. The outer shell is generally made of plastic to meet the requirements of aesthetic and diverse designs; the inner tank 100 can be made of metal or plastic, depending on the needs.

[0068] In addition, the insulation layer formed between the outer shell and the inner liner 100 is commonly made of materials such as asbestos, sponge, foam plastic, and polyurethane foam. In conventional technology, foaming is usually used to form the insulation layer in order to obtain a good insulation effect.

[0069] Among them, for the inner tank 100 with a metal liner, the inside of the inner tank 100 is prone to corrosion due to the influence of water quality. Therefore, a magnesium rod is also provided on the water tank, which is inserted into the water storage cavity inside the water tank.

[0070] Magnesium has the lowest electrochemical potential among metals and is physiologically non-toxic. Therefore, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod directly affects the duration and effectiveness of the protection; the larger the magnesium rod, the better the protection and the longer the protection time.

[0071] The water tank is also equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to deliver cold water into the water storage cavity formed inside the water tank, while the hot water in the water storage cavity is output from the outlet pipe.

[0072] For electric heating components, electric heating methods such as electric heating wires, magnetic energy, or silicon tube heating can be used to heat the water stored in the water storage chamber.

[0073] The control board receives detection signals from relevant sensors (such as water temperature sensors and flow sensors) and controls the power supply to the electric heating element. When the electric water heater is working, the control board controls the electric heating element to heat the water. When the water temperature in the tank reaches the set value, the control board controls the electric heating element to turn off the power.

[0074] In some embodiments of this application, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, an electric water heater is provided for horizontal installation along a horizontal direction.

[0075] The electric water heater includes a horizontal inner tank assembly, which includes an inner tank 100, a heating element assembly 200, an inlet pipe assembly 300, and an outlet pipe assembly 400.

[0076] The inner liner 100 has an installation cavity 110 therein, and the inner liner 100 has a first installation position 120, a second installation position 130 and a third installation position 140 that communicate with the installation cavity 110.

[0077] A heating tube assembly 200 extends horizontally and is disposed within the mounting cavity 110, and is connected to the first mounting position 120;

[0078] The water inlet pipe assembly 300 extends horizontally and is disposed in the mounting cavity 110, and is connected to the second mounting position 130;

[0079] The water outlet pipe assembly 400 extends horizontally and is disposed in the mounting cavity 110, and is connected to the third mounting position 140;

[0080] The first mounting position 120 is formed on the first side end of the inner tank 100 in the horizontal direction, and the second mounting position 130 and the third mounting position 140 are formed on the second side ends of opposite sides of the inner tank 100 in the horizontal direction. When the horizontal inner tank 100 assembly is in the installation direction, the water inlet pipe assembly 300, the heating pipe assembly 200 and the water outlet pipe assembly 400 are arranged at intervals from low to high in the height direction.

[0081] The water outlet pipe assembly 400 includes a horizontal extension section 410 and a wall-hugging bending section 420. The first end of the horizontal extension section 410 is connected to the third mounting position 140. The horizontal extension section 410 extends in a horizontal direction. The second end of the horizontal extension section 410 is connected to the wall-hugging bending section 420. The wall-hugging bending section 420 bends toward the top wall of the mounting cavity 110.

[0082] The wall-mounted bending section 420 extends along an arc-shaped trajectory from the second end of the horizontal extension section 410 to the top wall near the mounting cavity 110.

[0083] In some embodiments of this application, the horizontal inner liner assembly further includes a temperature measuring tube assembly 500, which extends along the extension direction of the water outlet pipe assembly 400, and the temperature measuring tube assembly 500 is arranged adjacent to the water outlet pipe assembly 400.

[0084] A fourth mounting position 150 is formed on the inner liner 100. The temperature measuring tube assembly 500 is inserted into the mounting cavity 110 from the fourth mounting position 150. The temperature measuring tube assembly 500 is connected to the fourth mounting position 150, which is formed at the first side end of the inner liner 100.

[0085] The horizontal inner liner assembly also includes a flange 160 and fastening components, with the flange 160 fitted at the first mounting position 120;

[0086] The heating tube assembly 200 includes a heating tube 210 and a heating tube flange base 220. One end of the heating tube 210 is connected to the heating tube flange base 220, and the other end of the heating tube 210 extends toward the second side end of the inner liner 100.

[0087] The heating tube flange base 220 abuts against the flange 160, and the heating tube flange base 220 is detachably connected to the flange 160 by a fastening assembly.

[0088] The heating tube assembly 200 extends into the lower part of the mounting cavity 110.

[0089] The horizontal inner liner assembly also includes a sealing component, which is clamped between the heating tube flange base 220 and the flange 160.

[0090] like Figure 8 , Figure 9 As shown, an installation cavity 110 is formed inside the inner liner 100. The installation cavity 110 is used to accommodate the heating tube assembly 200, the water inlet pipe assembly 300, and the water outlet pipe assembly 400.

[0091] The mounting cavity 110 is used to hold water.

[0092] Since the horizontal inner liner assembly extends horizontally, the inner liner 100 is also set horizontally.

[0093] The heating tube assembly 200 extends horizontally and is disposed within the mounting cavity 110 of the inner liner 100.

[0094] The water inlet pipe assembly 300 extends horizontally and is installed in the mounting cavity 110 of the inner liner 100.

[0095] The water outlet pipe assembly 400 extends horizontally and is installed in the mounting cavity 110 of the inner tank 100.

[0096] To enable the heating element assembly 200 to be installed on the inner liner 100, a first mounting position 120 is formed on the inner liner 100, and the first mounting position 120 communicates with the mounting cavity 110. The heating element assembly 200 is installed in the mounting cavity 110 through the first mounting position 120.

[0097] The first mounting position 120 is a through hole opened at the end of the inner liner 100. The heating tube assembly 200 extends into the inner liner 100 through the through hole.

[0098] To facilitate the installation of the water inlet pipe assembly 300 on the inner liner 100, a second mounting position 130 is formed on the inner liner 100, which communicates with the mounting cavity 110. The water inlet pipe assembly 300 is installed in the mounting cavity 110 through the second mounting position 130.

[0099] The second mounting position 130 is a first columnar structure 131 formed at the end of the inner liner 100. A first through cavity 132 is formed in the first columnar structure 131, and the first through cavity 132 is connected to the mounting cavity 110.

[0100] The water inlet pipe assembly 300 is inserted into the mounting cavity 110 through the first through cavity 132.

[0101] To facilitate the installation of the outlet pipe assembly 400 on the inner tank 100, a third mounting position 140 is formed on the inner tank 100, which communicates with the mounting cavity 110. The inlet pipe assembly 300 is installed in the mounting cavity 110 through the third mounting position 140.

[0102] The third mounting position 140 is a second columnar structure 141 formed at the end of the inner liner 100. A second through cavity 142 is formed in the second columnar structure 141, and the second through cavity 142 is connected to the mounting cavity 110.

[0103] The water outlet pipe assembly 400 is inserted into the mounting cavity 110 through the second through cavity 142.

[0104] In some embodiments of this application, the first column structure 131, the second column structure 141, and the inner liner 100 may be integrally formed.

[0105] In some other embodiments of this application, the first column structure 131 and the second column structure 141 are connected to the inner liner 100 by welding.

[0106] In some embodiments of this application, an electronic control board is provided between the shell and the inner liner 100, on the side near the first mounting position 120 connected to the heating tube assembly 200.

[0107] The control board is positioned adjacent to the first mounting position 120.

[0108] There is a risk of leakage at the connection points between the inlet pipe assembly 300, the outlet pipe assembly 400 and the inner tank 100, namely at the second installation position 130 and the third installation position 140.

[0109] If the first mounting position 120 is set adjacent to the second mounting position 130 and the third mounting position 140, and water leakage occurs at the second mounting position 130 or the third mounting position 140, it may easily cause leakage risk at the heating tube assembly 200 and the control board.

[0110] Therefore, the first mounting position 120, the second mounting position 130, and the third mounting position 140 are respectively located on opposite sides of the inner liner 100 along the horizontal direction. In the event of leakage in the water inlet pipe assembly 300 or the water outlet pipe assembly 400 at the second mounting position 130 or the third mounting position 140, the leakage will not affect the electrical control board or the heating element assembly 200 inside the housing.

[0111] Specifically, the first mounting position 120 is formed on the first side end of the inner liner 100 in the horizontal direction.

[0112] The second mounting position 130 and the third mounting position 140 are formed on the second side end of the inner liner 100 in the horizontal direction.

[0113] The first side end is the first end cap, and the second side end is the second end cap. The first end cap and the second end cap are respectively arc-shaped cap structures extending from the two sides of the inner liner 100.

[0114] In some embodiments of this application, the horizontal inner tank assembly is in the installation direction, and the water inlet pipe assembly 300, the heating pipe assembly 200 and the water outlet pipe assembly 400 are arranged at intervals from low to high along the height direction.

[0115] The second mounting position 130, the first mounting position 120, and the third mounting position 140 are arranged from low to high along the height direction.

[0116] Cold water enters the mounting cavity 110 of the inner tank 100 from the lower second mounting position 130, is heated by the heating pipe assembly 200 located above the water inlet pipe assembly 300, and then flows out through the water outlet pipe assembly 400 located above.

[0117] Because cold water is distributed in the lower part of the mounting cavity 110, and hot water rises to the upper part of the mounting cavity 110, the arrangement of the inlet pipe assembly 300 located in the lower part of the mounting cavity 110 and the outlet pipe assembly 400 located in the upper part of the mounting cavity 110 conforms to the natural distribution of cold and hot water in the mounting cavity 110, avoids disrupting the distribution of cold and hot water in the mounting cavity 110, thereby improving the hot water output rate, accelerating the circulation of cold and hot water, and reducing heat loss.

[0118] In some embodiments of this application, the portion of the heating tube assembly 200 extending into the mounting cavity 110 is bent toward the lower part of the mounting cavity 110 of the inner liner 100. The main heating portion of the heating tube assembly 200 is located at the lower part of the inner liner 100.

[0119] In some embodiments of this application, the inlet pipe assembly 300 and the outlet pipe assembly 400 are arranged symmetrically with respect to the axis of the inner liner 100.

[0120] The inlet pipe assembly 300 is located below the axis of the inner tank 100. The outlet pipe assembly 400 is located above the axis of the inner tank 100.

[0121] Specifically, the inlet pipe assembly 300 is located directly below the axis of the inner tank 100, and the outlet pipe assembly 400 is located directly above the axis of the inner tank 100. The inlet pipe assembly 300 and the outlet pipe assembly 400 are equidistant from the axis of the inner tank 100.

[0122] The second mounting position 130 and the third mounting position 140 are symmetrically arranged at equal intervals relative to their axes.

[0123] In some embodiments of this application, such as Figure 8 As shown, the water outlet pipe assembly 400 includes a horizontal extension section 410 and a wall-mounted bend section 420.

[0124] The first end of the horizontal extension 410 is connected to the third mounting position 140. The first end of the horizontal extension 410 is mounted at the third mounting position 140.

[0125] The horizontal extension 410 extends horizontally within the mounting cavity 110.

[0126] The second end of the horizontal extension 410 is connected to the wall-mounted bending section 420.

[0127] The wall-mounted bending section 420 extends along an arc-shaped trajectory from the second end of the horizontal extension section 410 to the top wall near the mounting cavity 110.

[0128] The wall-adhering bending section 420 bends from the second end of the horizontal extension section 410 toward the top wall of the mounting cavity 110.

[0129] The wall-mounted bending section 420 extends along an arc-shaped trajectory from the second end of the horizontal extension section 410 to the top wall near the mounting cavity 110.

[0130] A certain gap is maintained between the wall-mounted bending section 420 and the top wall of the mounting cavity 110. Hot water in the mounting cavity 110 enters the wall-mounted bending section 420 through this gap.

[0131] Therefore, due to the natural distribution of hot and cold water in the installation cavity 110, the water with a higher temperature in the installation cavity 110 can enter the water outlet pipe assembly 400 from the wall-mounted bend section 420 and be transported to the third installation position 140 through the horizontal extension section 410.

[0132] Specifically, both the horizontal extension section 410 and the wall-mounted bend section 420 are tubular structures. Hot water can flow within them.

[0133] In some embodiments of this application, a water inlet is provided at the second mounting position 130.

[0134] In some embodiments of this application, a water outlet is provided at the third mounting position 140.

[0135] Hot water flows from the outlet to the outlet pipe assembly 400.

[0136] Because the end of the wall-mounted bending section 420 is located close to the top wall of the mounting cavity 110, the hot water causes less disturbance to the water contained in the mounting cavity 110 during the process of entering the wall-mounted bending section 420.

[0137] In some embodiments of this application, the horizontal inner tank assembly further includes a temperature sensing tube assembly 500. The temperature sensing tube assembly 500 is used to detect the outlet water temperature of the inner tank 100.

[0138] Therefore, the temperature sensing tube assembly 500 and the water outlet pipe assembly 400 are arranged adjacent to each other. This facilitates the detection of the water outlet temperature from the inner tank 100, thus enabling more accurate detection of the water outlet temperature of the water heater.

[0139] In some embodiments of this application, the temperature measuring tube assembly 500 extends along the extension direction of the water outlet tube assembly 400.

[0140] A fourth mounting position 150 is formed on the inner liner 100. The fourth mounting position 150 is used to mount the temperature measuring tube assembly 500.

[0141] The fourth mounting position 150 and the first mounting position 120 are located on the same side of the inner liner 100.

[0142] The fourth mounting position 150 and the first mounting position 120 are both formed on the first side end of the inner liner 100.

[0143] The temperature measuring tube assembly 500 is inserted into the mounting cavity 110 from the fourth mounting position 150, and the temperature measuring tube assembly 500 is connected to the fourth mounting position 150.

[0144] The fourth mounting position 150 can take the form of a third column structure 151.

[0145] An installation hole is provided at the first side end of the inner liner 100, and a third column structure 151 is inserted into the installation hole. The third column structure 151 passes through the installation hole and the end of the third column structure 151 is inserted into the installation cavity 110.

[0146] A third through cavity is formed within the third column-shaped structure 151. The temperature sensing tube assembly 500 extends from the third through cavity into the mounting cavity 110, thereby enabling the installation of the temperature sensing tube assembly 500.

[0147] In some embodiments of this application, such as Figure 8 , Figure 10As shown, the first mounting position 120 is an opening 121 formed at the first side end of the inner liner 100 and a flange 122 formed at the opening 121 at the first side end of the inner liner 100.

[0148] Specifically, opening 121 is located at the center of the first end cap.

[0149] In some embodiments of this application, the horizontal inner liner assembly further includes a flange 160. The flange 160 is fitted at the first mounting position 120. The flange 160 abuts against the wall of the opening 121.

[0150] An annular gap is formed between the flange 122 and the inner liner 100.

[0151] The inner end of flange 160 is inserted into the annular gap to achieve the connection between the two.
