Description
Technical Field
[0001] This utility model belongs to the field of electric water heater installation technology, and in particular relates to a pad structure for installing an electric water heater and an electric water heater. Background Technology
[0002] Currently, water heaters are common household appliances, categorized into gas water heaters, electric water heaters, heat pump water heaters, and solar water heaters. Electric water heaters are widely used due to their convenience. Electric water heaters can be further classified by heating power into storage-type and instantaneous types. Storage-type water heaters, equipped with a water tank, offer advantages such as large water output and stable water temperature, making them more popular among families. Electric water heaters are typically mounted on walls using external wall mounts. These mounts are secured to the water heater casing and inner tank using bolts. To ensure installation stability, the mounting brackets are generally large. Since the bolts and brackets are made of metal with high thermal conductivity, the water heater generates significant heat.
[0003] A Chinese patent with publication number CN222811935U discloses an inner tank support structure and a water heater, which is applied to a water heater. The water heater includes an inner tank and a shell sleeved on the inner tank. The inner tank support structure includes a connecting bracket, a support pad, and a first connecting member. The connecting bracket is used to be installed inside the shell and connected to the inner tank. The support pad includes an installation part and an abutment part arranged in sequence. The installation part is connected to the connecting bracket, and the abutment part is used to abut against the inner tank support. The first connecting member is used to fix the installation part to the shell.
[0004] The aforementioned inner tank support structure, by incorporating support pads, including an mounting portion and an abutment portion, allows for direct contact and support with the inner tank, reducing the volume of the connecting support and thus minimizing heat dissipation from the inner tank at the connection point. However, during the threaded connection of the connector through the opening in the outer shell to the abutment portion, a certain biasing force is exerted on the support pads, creating a gap between the support pads and the outer shell. During the foaming process of the electric water heater, the foaming material easily overflows along the gaps and openings, preventing the insulation layer from completely covering the cavity between the inner tank and the outer shell, thereby affecting the insulation effect. Therefore, designing a technology to reduce the overflow of foaming material in electric water heaters is the technical problem this invention aims to solve. Utility Model Content
[0005] This utility model provides a pad structure for installing an electric water heater and an electric water heater, which reduces the overflow of foaming material in the electric water heater to improve the heat preservation effect of the electric water heater.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] In a first aspect, this utility model provides a pad structure for installing an electric water heater, applied to an electric water heater including an inner tank, an outer shell sleeved outside the inner tank, an external wall bracket for supporting the electric water heater, and a bracket connected to the inner tank. The pad structure is located between the inner tank and the outer shell, and the pad structure includes:
[0008] The mounting part is located between the bracket and the housing;
[0009] A support portion, which is connected to the mounting portion and located on one side of the mounting portion, is configured to support between the outer shell and the inner liner;
[0010] The wall mount has a first positioning hole, and the outer casing has a second positioning hole corresponding to the first positioning hole. Fasteners pass through the first and second positioning holes to fix the wall mount to the outer casing. The support portion has a recessed portion corresponding to the fastener, with the opening of the recessed portion facing the second positioning hole. The bottom of the recessed portion is a closed structure, and the recessed portion is configured to accommodate the fastener.
[0011] In some embodiments of this application, the support portion includes a connecting section and an abutting section. The connecting section is used to connect the abutting section and the mounting portion. The abutting section abuts between the inner liner and the outer shell. The recess is formed on the connecting section and / or the abutting section.
[0012] By including a connecting section and an abutting section in the support part, the abutting section abuts between the inner tank and the outer shell. The abutting section can form a support together with the bracket to maintain the gap between the inner tank and the outer shell, which helps to improve the structural stability and heat preservation effect of the electric water heater.
[0013] In some embodiments of this application, a positioning structure is formed on the external wall bracket, and an insertion hole is formed on the outer shell for the positioning structure to pass through. The opening end of the recess covers the insertion hole to accommodate the positioning structure.
[0014] By forming a positioning structure on the exterior wall bracket and having insertion holes on the outer shell for the positioning structure to pass through, the positioning structure and insertion holes can better position the exterior wall bracket on the outer shell during installation, which is beneficial to improving installation efficiency and accuracy. The opening end of the recessed part covers the insertion hole, which can prevent foaming liquid from overflowing at the insertion hole.
[0015] In some embodiments of this application, the positioning structure includes an insert, which is a bent structure formed by punching holes in the external wall bracket.
[0016] By forming the inserts through punching holes in the exterior wall brackets, waste generation can be reduced, processing and manufacturing can be facilitated, and costs can be saved. The bent structure of the inserts makes it easier for them to be attached to the sockets, which is convenient for operation.
[0017] In some embodiments of this application, the external wall bracket has a mounting surface facing the outer shell, the mounting surface being adapted to the curvature of the outer wall surface of the outer shell, and the first positioning hole and the positioning structure are both disposed on the mounting surface.
[0018] By forming an installation surface on the side of the exterior wall bracket facing the outer shell, and adapting the installation surface to the curvature of the outer wall surface of the outer shell, the exterior wall bracket can better fit against the outer shell, increasing the contact area between the exterior wall bracket and the outer shell and improving structural stability; by setting the first positioning hole and positioning structure on the installation surface, it is convenient for fasteners and inserts to connect the exterior wall bracket and the outer shell more tightly together.
[0019] In some embodiments of this application, the exterior wall bracket, the outer shell, the mounting part, and the bracket are coaxially provided with a third positioning hole, and the connector passes through the third positioning hole on the exterior wall bracket, the outer shell, the mounting part, and the bracket to fix the exterior wall bracket, the outer shell, the pad structure, and the inner liner together.
[0020] By coaxially providing a third positioning hole on the exterior wall bracket, outer shell, mounting part, and bracket, the connector passes through the third positioning hole to fix the exterior wall bracket, outer shell, pad structure, and bracket together. On the one hand, the mounting part of the pad structure is located between the outer shell and the bracket, avoiding direct contact between the outer shell and the bracket, which can reduce heat loss; on the other hand, under the connection of the connector, the exterior wall bracket, outer shell, pad structure, and bracket form a whole, making it easy to install the electric water heater on the wall.
[0021] In some embodiments of this application, the connector includes:
[0022] Screw;
[0023] A nut, which is embedded in the mounting part and is threadedly connected to the screw.
[0024] By using a connector including a screw and a nut, with the nut embedded in the mounting part, and a third positioning hole coaxially provided on the exterior wall bracket, the outer shell, the mounting part, and the bracket, the screw can pass through the third positioning hole and be threadedly connected to the nut, thereby connecting the exterior wall bracket to the outer shell and the inner liner.
[0025] In some embodiments of this application, the mounting portion includes a first mounting section and a second mounting section connected together, a slot is formed between the first mounting section and the second mounting section, the bracket is inserted into the slot, and the third positioning hole is coaxially provided on the first mounting section and the second mounting section.
[0026] By providing a slot between the first and second mounting sections, the bracket is inserted into the slot, which facilitates fixing the relative position of the pad structure and the bracket.
[0027] In some embodiments of this application, a snap-fit connector is formed on the first mounting segment and / or the second mounting segment. The snap-fit connector is located at the open end of the mounting portion and is configured to engage with the bracket to prevent the bracket from dislodging from the slot.
[0028] By providing snap-fit connectors on the first and / or second mounting sections, with the snap-fit connectors located at the open end of the mounting section, the snap-fit connectors can engage with the bracket to prevent the bracket from coming out of the slot, thereby improving the stability of the connection between the pad structure and the bracket.
[0029] In a second aspect, the present invention provides an electric water heater, including a pad structure for mounting the electric water heater as described in any of the embodiments of the first aspect above.
[0030] Compared with the prior art, the advantages and positive effects of this utility model are as follows: The pad structure for installing an electric water heater includes a connected mounting part and a supporting part. The supporting part is located on one side of the mounting part and is used to support the inner tank and the outer shell. A first positioning hole is formed on the outer wall bracket of the electric water heater, and a second positioning hole is formed on the outer shell. Fasteners pass through the first and second positioning holes to connect the outer wall bracket to the outer shell. A recessed part is formed on the supporting part at a position corresponding to the fastener. The opening of the recessed part faces the second positioning hole. The recessed part is used to accommodate the fastener, and the bottom of the recessed part is a closed structure. In this way, the supporting part avoids the fastener through the recessed part. When the fastener is installed, the fastener will not exert force on the pad structure, and there will be no gap between the pad structure and the outer shell. At the same time, the bottom of the recessed part is a closed structure, so the foaming material will not enter the recessed part during the foaming process of the electric water heater, avoiding the overflow of the foaming material and improving the heat preservation effect of the electric water heater.

[0054] An electric water heater is a type of water heater that uses electricity as its primary energy source. The high-temperature heat generated after the power is turned on directly heats the water stored in the water heater to produce hot water.
[0055] 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.
[0056] For the water tank of an electric water heater, the tank generally consists of an outer shell and an inner tank, with an insulation layer between them. The outer shell is usually made of plastic to meet the requirements of aesthetic and diverse designs; the inner tank can be made of metal or plastic, depending on the needs.
[0057] In addition, the insulation layer formed between the outer shell and the inner liner 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 achieve good insulation effect.
[0058] For water tanks with metal inner liner, corrosion can easily occur inside due to water quality. Therefore, magnesium rods are installed on the water tank and inserted into the water storage cavity inside the tank.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] The electronic control board is used to receive detection signals from relevant sensors, such as water temperature sensors and flow sensors, and at the same time, to control the power supply to and from the electric heating components.
[0063] When the electric water heater is working, the electric control board controls the electric heating element to be powered on and heated. When the water temperature in the tank reaches the set value, the electric control board controls the electric heating element to be powered off.
[0064] In one respect, combination Figures 1 to 10 This disclosure provides an electric water heater, which includes an inner tank 1 and an outer shell 2. The inner tank 1 stores hot water, and the outer shell 2 is coaxially sleeved around the inner tank 1. Figure 5 and Figure 6 A bracket 11 is provided between the outer shell 2 and the inner liner 1. The bracket 11 is fixedly connected to the inner liner 1, and the outer shell 2 and the inner liner 1 are connected by the bracket 11.
[0065] Combination Figure 1 and Figure 2 The electric water heater also includes an external wall bracket 4, which is located on the outside of the outer casing 2. The external wall bracket 4 is fixedly connected to the bracket 11 to clamp the outer casing 2 between the bracket 11 and the external wall bracket 4. The external wall bracket 4 is also connected to the wall to hang the water heater on the wall.
[0066] Specifically, the bracket 11 and the inner liner 1 can be connected by welding, riveting or other methods.
[0067] Since the bracket 11 is a metal part, when the bracket 11 comes into contact with the outer shell 2, it can directly transfer the heat of the inner tank 1 to the outer shell 2, which will reduce the heat preservation of the electric water heater. Therefore, a pad structure 3 needs to be set between the bracket 11 and the outer shell 2 to avoid direct contact between the bracket 11 and the outer shell 2.
[0068] In a first aspect, embodiments of the present disclosure provide a pad structure 3 for installing an electric water heater. The pad structure 3 is applied to the electric water heater and is located between the inner tank 1 and the outer shell 2. The pad structure 3 includes an installation part 31 and a support part 32.
[0069] The mounting part 31 is located between the bracket 11 and the outer shell 2; the support part 32 is connected to the mounting part 31 and located on one side of the mounting part 31. The support part 32 is configured to support between the outer shell 2 and the inner liner 1. During actual installation, the support part 32 is located below the mounting part 31. The mounting part 31 bears the force applied by the inner liner 1 and the bracket 11, and the support part 32 bears the pressure of the inner liner 1 so that the pad structure 3 provides stable support.
[0070] Among them, combined Figure 3 and Figure 4 The exterior wall bracket 4 has a first positioning hole 41, and the outer shell 2 has a second positioning hole 21. The second positioning hole 21 corresponds to the first positioning hole 41. The fastener 6 passes through the first positioning hole 41 and the second positioning hole 21 to fix the exterior wall bracket 4 to the outer shell 2. The support part 32 has a recessed part 321 at the position corresponding to the fastener 6. The opening of the recessed part 321 faces the second positioning hole 21. The bottom of the recessed part 321 is a closed structure. The recessed part 321 is configured to accommodate the fastener 6.
[0071] Specifically, the pad structure 3 for installing the electric water heater includes a mounting part 31 and a support part 32 connected together. The support part 32 is located on one side of the mounting part 31 and is used to support the inner tank 1 and the outer shell 2. The outer wall bracket 4 of the electric water heater has a first positioning hole 41, and the outer shell 2 has a second positioning hole 21. The fastener 6 passes through the first positioning hole 41 and the second positioning hole 21 to connect the outer wall bracket 4 and the outer shell 2. The support part 32 has a recessed part 321 at a position corresponding to the fastener 6. The opening of the recessed part 321 is... Facing the second positioning hole 21, the recess 321 is used to accommodate the fastener 6, and the bottom of the recess 321 is a closed structure; in this way, the support part 32 avoids the fastener 6 through the recess 321, and when the fastener 6 is installed, the fastener 6 will not exert force on the pad structure 3, and there will be no gap between the pad structure 3 and the outer shell 2; at the same time, the bottom of the recess 321 is a closed structure, and the foaming material will not enter the recess 321 during the foaming process of the electric water heater, avoiding the overflow of the foaming material, which is conducive to improving the heat preservation effect of the electric water heater.
[0072] Specifically, fastener 6 includes screws, bolts, or rivets.
[0073] Specifically, the mounting part 31 and the support part 32 are integrally formed structures.
[0074] In some embodiments of this application, combined with Figure 7 The support portion 32 includes a connecting section 322 and an abutting section 323. The connecting section 322 is used to connect the abutting section 323 and the mounting portion 31. The abutting section 323 abuts between the inner liner 1 and the outer shell 2. A recess 321 is formed on the connecting section 322 and / or the abutting section 323.
[0075] Specifically, by including a connecting section 322 and an abutting section 323 in the support part 32, the overall span of the support part 32 is relatively large. The abutting section 323 abuts between the inner tank 1 and the outer shell 2. The abutting section 323 can form a support together with the bracket 11 to maintain the gap between the inner tank 1 and the outer shell 2, which is conducive to improving the structural stability and heat preservation effect of the electric water heater.
[0076] Specifically, in order to reduce heat transfer, the pad structure 3 is made of heat-insulating material; for example, the pad structure 3 is made of plastic material.
[0077] In some embodiments of this application, a positioning structure 42 is formed on the external wall bracket 4, and an insertion hole 22 is formed on the outer shell 2 for the positioning structure 42 to pass through. The opening end of the recess 321 covers the insertion hole 22 to accommodate the positioning structure 42.
[0078] Specifically, by forming a positioning structure 42 on the exterior wall bracket 4 and forming an insertion hole 22 on the outer shell 2 for the positioning structure 42 to pass through, when installing the exterior wall bracket 4, the positioning structure 42 and the insertion hole 22 cooperate to better position the exterior wall bracket 4 on the outer shell 2, which is beneficial to improve installation efficiency and installation accuracy; the opening end of the recessed part 321 covers the insertion hole 22, which can prevent the foaming liquid from overflowing at the insertion hole 22.
[0079] In some embodiments of this application, the positioning structure 42 includes a insert, which is a bent structure formed by punching holes in the external wall bracket 4.
[0080] Specifically, by punching holes in the external wall bracket 4 to form the insert, the insert has high strength, which can reduce waste generation, simplify the process, facilitate manufacturing, and help save costs; the insert has a bent structure, which makes it easier for the insert to be attached to the socket 22, making it convenient to operate.
[0081] In some other embodiments of this application, the insert is fixed to the external wall bracket 4 by welding.
[0082] In some embodiments of this application, the external wall bracket 4 has a mounting surface 43 on the side facing the outer shell 2. The mounting surface 43 is adapted to the curvature of the outer wall surface of the outer shell 2. The first positioning hole 41 and the positioning structure 42 are both provided on the mounting surface 43.
[0083] Specifically, by forming an installation surface 43 on the side of the exterior wall bracket 4 facing the outer shell 2, and adapting the curvature of the installation surface 43 to the outer wall surface of the outer shell 2, the exterior wall bracket 4 can better fit against the outer shell 2, increasing the contact area between the exterior wall bracket 4 and the outer shell 2 and improving structural stability; by setting both the first positioning hole 41 and the positioning structure 42 on the installation surface 43, it is convenient for the fasteners 6 and the inserts to connect the exterior wall bracket 4 and the outer shell 2 more tightly together.
[0084] In some embodiments, the upper part of the exterior wall bracket 4 is formed with a hanging hole for a hook to pass through, and the lower part of the exterior wall bracket 4 is formed with a fixing hole for fixing the exterior wall bracket 4 to the wall. The mounting surface 43 is located between the hanging hole and the fixing hole.
[0085] In some embodiments of this application, the exterior wall bracket 4, the outer shell 2, the mounting part 31 and the bracket 11 are coaxially provided with a third positioning hole 44, and the connector 5 passes through the third positioning hole 44 on the exterior wall bracket 4, the outer shell 2, the mounting part 31 and the bracket 11 to fix the exterior wall bracket 4, the outer shell 2, the pad structure 3 and the inner liner 1.
[0086] Specifically, a third positioning hole 44 is coaxially provided on the external wall bracket 4, the outer shell 2, the mounting part 31, and the bracket 11. The connector 5 passes through the third positioning hole 44 to fix the external wall bracket 4, the outer shell 2, the pad structure 3, and the bracket 11. On the one hand, the mounting part 31 of the pad structure 3 is located between the outer shell 2 and the bracket 11, avoiding direct contact between the outer shell 2 and the bracket 11, which can reduce heat loss. On the other hand, under the connection of the connector 5, the external wall bracket 4, the outer shell 2, the pad structure 3, and the bracket 11 form a whole, which makes it easy to install the electric water heater on the wall.
[0087] In some embodiments of this application, combined with Figure 10 The connector 5 includes a screw 51 and a nut 52. The nut 52 is embedded in the mounting part 31 and is threadedly connected to the screw 51.
[0088] Specifically, by connecting the connector 5, which includes a screw 51 and a nut 52, with the nut 52 embedded in the mounting part 31, and by providing a third positioning hole 44 coaxially on the external wall bracket 4, the outer shell 2, the mounting part 31, and the bracket 11, the screw 51 can pass through the third positioning hole 44 and be threadedly connected to the nut 52, thereby connecting the external wall bracket 4 with the outer shell 2 and the inner liner 1.
[0089] In some embodiments of this application, combined with Figure 8 The mounting section 31 has a U-shaped structure and includes a first mounting section 311 and a second mounting section 312 connected to each other. A slot 313 is formed between the first mounting section 311 and the second mounting section 312. It is understood that the first mounting section 311 and the second mounting section 312 are arranged radially apart along the inner liner 1 so that the slot 313 can be adapted to the bracket 11. The bracket 11 is inserted into the slot 313. The first mounting section 311 and the second mounting section 312 are located on both sides of the bracket 11. A third positioning hole 44 is coaxially provided on the first mounting section 311 and the second mounting section 312.
[0090] Specifically, by providing a slot 313 between the first mounting section 311 and the second mounting section 312, the bracket 11 is inserted into the slot 313, which facilitates fixing the relative position of the pad structure 3 and the bracket 11.
[0091] In some embodiments of this application, combined with Figure 9A snap-fit connector 314 is formed on the first mounting section 311 and / or the second mounting section 312. The snap-fit connector 314 is located at the open end of the mounting portion 31 and is configured to snap with the bracket 11 to prevent the bracket 11 from dislodging from the slot 313.
[0092] Specifically, by providing a snap-fit connector 314 on the first mounting section 311 and / or the second mounting section 312, the snap-fit connector 314 is located at the open end of the mounting part 31. The snap-fit connector 314 can engage with the bracket 11 to prevent the bracket 11 from coming out of the slot 313, thereby improving the stability of the connection between the pad structure 3 and the bracket 11.
[0093] Specifically, the end of the snap connector 314 has a guide slope 3141, which guides the insertion of the bracket 11 and the mounting part 31.
[0094] Specifically, there is a gap between the snap connector 314 and the main body of the mounting part 31, which facilitates the deformation of the snap connector 314 and allows the bracket 11 to be snapped into the slot 313 more smoothly.
[0095] In some embodiments of this application, a plurality of first support ribs 315 are provided on both the first mounting section 311 and the second mounting section 312, and the plurality of first support ribs 315 are arranged in a cross manner to form a first heat insulation groove 316.
