[0002] A water heater consists of a water tank, an electric heating element, and a control board. The water tank has a storage cavity to hold water to be heated. The electric heating element is inserted into this cavity. The control board controls the on / off operation of the heating element to heat the water to the set temperature. The water tank typically consists of an outer shell and an inner tank, with an insulation layer between them.

[0003] There is a type of vertical kitchen water heater where the inner pot is vertically positioned inside the outer shell. Positioning protrusions and grooves are provided between the bottom of the inner pot and the bottom of the outer shell to pre-position the inner pot and prevent it from shifting during the foaming process. However, the positioning protrusions and grooves are usually located in the middle of the bottom of the inner pot, resulting in only one positioning point. Therefore, the inner pot can still tilt or shift during the foaming process.

[0032] Horizontal water heaters, such as horizontal kitchen water heaters, use electricity as their main energy source. The high-temperature heat generated after being powered on directly heats the water stored in the horizontal kitchen water heater to produce hot water.

[0033] A horizontal kitchen water heater typically consists of a water tank, an electric heating element, and an electronic control board. The water tank has a water storage cavity to store water to be heated. The electric heating element is inserted into the water storage cavity. The electronic control board is used to control the on / off operation of the electric heating element so that the water in the tank is heated to the set temperature.

[0034] For horizontal kitchen water heaters, the water tank generally consists of an outer shell and an inner liner, 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 liner can be made of metal or plastic, depending on the needs.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The control board is used to receive detection signals from relevant sensors (such as water temperature sensors and flow sensors) and control the power supply to and from the electric heating components.

[0040] When the horizontal water heater is working, the electric heating element is powered on by the control board. When the water temperature in the tank reaches the set value, the electric heating element is powered off by the control board.

[0041] In some embodiments of this application, reference is made to Figure 1 and Figure 2 A horizontal kitchen water heater is provided, including a housing 1, the bottom of which forms a mounting support surface. The mounting support surface allows the water heater to be placed in a cabinet during installation in a user's home, eliminating the need for hanging.

[0042] The horizontal kitchen water heater also includes an inner pot 2, and an installation cavity is formed inside the outer shell. The inner pot 2 is horizontally arranged in the installation cavity.

[0043] The height of the outer shell 1 is less than its length to allow for horizontal installation of the inner liner 2.

[0044] Typically, the height of a cabinet is limited but it has sufficient depth. Therefore, in this case, the inner liner 2 is installed horizontally, and the height of the outer shell 1 is less than its length. While ensuring the volume of the inner liner 2, the height of the outer shell is reduced, which facilitates the installation of the horizontal water heater in a cabinet with limited height.

[0045] The horizontal kitchen water heater also includes an electric heating element (not shown), which is disposed in the inner liner 2.

[0046] The horizontal kitchen water heater also includes an inlet and outlet pipe assembly 4, which includes an inlet pipe 41 and an outlet pipe 42, and the inlet pipe 41 and the outlet pipe 42 are sealed through the inner tank 2.

[0047] The water inlet pipe 41 is vertically installed in the inner tank 2, with the inlet end of the water inlet pipe 41 extending from the top of the outer shell 1. The water outlet pipe 42 is vertically installed in the inner tank 2, with the outlet end of the water outlet pipe 42 extending from the top of the outer shell 1.

[0048] The inlet pipe 41 and outlet pipe 42 are top-mounted, which facilitates the connection of water pipes when installing a horizontal water heater at the user's site. Furthermore, the horizontal water heater also facilitates the maintenance of the water pipes during use.

[0049] To achieve constant temperature water output, the inlet and outlet pipes 4 are also equipped with thermostatic valves 44. Specifically, the outlet end of the outlet pipe 42 is equipped with a thermostatic valve 44, the inlet end of the inlet pipe 41 is equipped with a tee pipe, and a connecting pipe 45 is also provided between the thermostatic valve 44 and the tee pipe.

[0050] The thermostatic valve 44 connected to the outlet pipe 42 is also connected to the tee pipe of the inlet pipe 41 through the connecting pipe 45. In actual use, when the outlet water temperature of the outlet pipe 42 is higher than the set temperature of the thermostatic valve 44, part of the cold water flowing in through the tee pipe enters the thermostatic valve 44 for automatic water temperature adjustment.

[0051] In some embodiments of this application, the top of the inner liner 2 is provided with a first mounting pipe 22 and a second mounting pipe 23. The first mounting pipe 22 is provided with a first connector 46, and the second mounting pipe 23 is provided with a second connector 47. The water inlet pipe 41 passes through the first mounting pipe 22 and the first connector 46, and the water outlet pipe 42 passes through the second mounting pipe 23 and the second connector 47.

[0052] Specifically, the first mounting tube 22 and the second mounting tube 23 are fixed to the top of the inner liner 2, and are arranged alternately. (Refer to...) Figure 5 The top of the outer casing 1 has two mounting ports 127. The first connector 46 and the second connector 47 protrude from the corresponding mounting ports 127 for connection to external water pipes. The inlet pipe 41 is connected to the external water pipe through the first connector 46, and the outlet pipe 42 is connected to the external water pipe through the second connector 47.

[0053] In some embodiments of this application, the outer casing 1 includes a base plate 11 and an upper cover 12. A mounting cavity is formed between the base plate 11 and the upper cover 12. Figure 4 This is a structural diagram of the base plate. Figure 5 This is a structural diagram of the upper cover.

[0054] The base plate 11 includes a bottom wall 011 and a circumferential wall 012. The bottom surface of the bottom wall 011 forms a support surface, and the circumferential wall 012 extends upward from the bottom wall 011 by a certain distance. A first mounting portion 013 is provided at the top of the circumferential wall 012, and a second mounting portion 016 is provided at the bottom of the upper cover 12. Fasteners (e.g., screws) pass through the first mounting portion 013 and the second mounting portion 016 from bottom to top to securely mount the base plate 11 and the upper cover 12. There is a distance between the fasteners and the bottom wall 011.

[0055] In other words, the circumferential wall 012 extends upward from the bottom wall 011 by a certain distance, and the circumferential wall 012 is fixedly connected to the upper cover 12 by screws. Since the circumferential wall 012 extends upward from the bottom wall 011 by a certain distance, there is a certain distance between the screws and the bottom wall 011. Therefore, when water accumulates on the surface where the kitchen water heater is placed, it can effectively prevent the screws from coming into contact with water, thereby preventing the screws from being corroded by water. This improves the connection reliability between the bottom plate 11 and the upper cover 12, and improves the connection reliability of the outer shell 1.

[0056] The circumferential wall 012 extends upward from the bottom wall 011 by a certain distance. The first mounting part 013 is located at the top of the circumferential wall 012, and the second mounting part 016 is located at the bottom of the upper cover 12. When the screw is driven into the first mounting part 013 and the second mounting part 016 from bottom to top, the distance between the circumferential wall 012 and the bottom wall 011 provides a certain installation space for the screw-tightening operation, which facilitates the screw-tightening operation.

[0057] In some embodiments of this application, a first mounting portion 013 is provided on the inner wall of the circumferential wall 012, an avoidance notch 014 is provided on the outer wall of the circumferential wall 012, a fastener passes through the avoidance notch 014 and through the first mounting portion 013, and a second mounting portion 016 is provided on the inner wall of the upper cover 12.

[0058] The clearance notch 014 provides clearance for screw driving operations, making the operation easier. Furthermore, the clearance notch 014 also shields the screw after installation, preventing the nut from being exposed.

[0059] In some embodiments of this application, in order to improve the connection reliability between the upper cover 12 and the base plate 11, the edge of the base plate 11 is provided with an upper flange structure 114, and the lower edge of the upper cover 12 wraps around the outside of the upper flange structure 114.

[0060] Specifically, when the upper cover 12 is assembled with the base plate 11, the upturned edge structure 114 formed by the edge of the base plate 11 is inserted into the inner edge of the upper cover 12 so that the upturned edge abuts against the inner wall of the upper cover 12, so that the base plate 11 and the upper cover 12 can be pre-assembled together.

[0061] In some embodiments of this application, an installation liner 18 is provided in the installation cavity, the installation liner 18 divides the installation cavity into a first cavity 191 and a second cavity 192, the first cavity 191 forms an electrical compartment, and the inner liner 2 is arranged laterally in the second cavity 192. Figure 3 A structural diagram for installing the liner 18.

[0062] Specifically, the mounting plate 18 is disposed between the upper cover 12 and the bottom plate 11, and the mounting plate 18 divides the mounting cavity into a first cavity 191 and a second cavity 192.

[0063] The access port is connected to the first cavity 191, the inner liner 2 is located in the second cavity 192, and the front panel 17 is detachably mounted on the upper cover 12 and covers the access port.

[0064] The horizontal kitchen water heater also includes an electrical control board, which is electrically connected to the electric heating tube. The first cavity 191 forms an electrical chamber, and the electrical control board is located in the electrical chamber.

[0065] Specifically, to facilitate the formation of an electrical compartment for installing electrical components such as the control board, the outer casing 1 also includes a front panel 17 and a mounting plate 18. The mounting plate 18 divides the mounting cavity into a first cavity 191 and a second cavity 192, thereby enabling independent installation of the inner liner 2 and the control board. Furthermore, the front panel 17 is detachably mounted on the upper cover 12, making it easier for maintenance personnel to open the front panel 17 to expose the control board and other electrical components inside the electrical compartment during future maintenance.

[0066] In some embodiments of this application, the electronic control board is connected to the temperature controller 152, and the knob 151 is connected to the temperature controller 152. The knob 151 is located on the left or right side wall of the housing 1.

[0067] Specifically, knob 151 is located on the left or right side wall of housing 1. By placing knob 151 on its side, the height of the horizontal water heater is not increased, which facilitates the installation of the horizontal water heater in under-sink spaces with limited height and makes it easier for users to operate.

[0068] In some embodiments of this application, a groove 181 is provided on the circumferential end face of the mounting liner 18, and the groove 181 extends circumferentially along the mounting liner 18. A protrusion is provided on the inner wall of the outer casing 1, and the groove 181 is sealed and inserted into the protrusion.

[0069] The mounting liner 18 is fixedly installed in the mounting cavity through the sealed insertion between the groove 181 and the protrusion. At the same time, since the inner liner 2 is located in the second cavity 192, foaming is required on the outer periphery of the inner liner 2 to form a foamed insulation layer. Through the sealed connection between the mounting liner 18 and the inner wall of the outer shell 1, the first cavity 191 and the second cavity 192 are completely isolated, preventing the foaming material in the second cavity 192 from entering the first cavity 191.

[0070] The groove 181 is integrally formed on the peripheral wall of the mounting liner 18, which facilitates processing, and the groove 181 also helps to improve the structural strength of the peripheral wall of the mounting liner 18.

[0071] Reference Figure 4 The base plate 11 has a lower protrusion 112, meaning that both the bottom wall 011 and the circumferential wall 012 of the base plate 11 have sequentially connected lower protrusions 112 flanged along their edges. (Refer to...) Figure 5 The upper cover 12 is provided with an upper protrusion 122, that is, the bottom wall 011 and the left and right side walls of the upper cover 12 are provided with an upper protrusion 122 connected in sequence.

[0072] During installation, first install the mounting liner 18 onto the base plate 11, with the mounting liner 18 interlocking with the lower protrusion 112; then, snap the upper cover 12 onto the base plate 11 from top to bottom, with the mounting liner 18 interlocking with the upper protrusion 122. This achieves the fixed installation of the mounting liner 18 and also serves as a pre-positioning mechanism for the base plate 11 and the upper cover 12, ensuring that the screw holes on the base plate 11 and the upper cover 12 are aligned vertically for subsequent screwing.

[0073] In some embodiments of this application, a plurality of spaced-apart support portions are provided on the inner wall surrounding the second cavity 192, and the plurality of support portions abut against the circumferential wall of the inner liner 2. The plurality of vertically arranged support portions limit the vertical movement of the inner liner 2, thereby improving the installation stability of the inner liner 2.

[0074] In some embodiments of this application, the top and bottom of the outer shell 1 are respectively provided with multiple support parts, and the mounting cavity is provided with two laterally opposite limiting parts. The inner liner 2 is laterally disposed in the mounting cavity, the multiple support parts abut against the circumferential wall of the inner liner 2, and the two limiting parts abut against the front end face and rear end face of the inner liner 2.

[0075] Specifically, the base plate 11 has multiple support parts, referred to as lower support parts 111, and the top wall of the upper cover 12 has multiple support parts, referred to as upper support parts 121. The multiple upper support parts 121 and the multiple lower support parts 111 are arranged vertically opposite each other. The front wall of the second cavity 192 has a limiting part, referred to as the first limiting part 182. The rear wall of the second cavity 192 has another limiting part, referred to as the second limiting part 123. Specifically, the first limiting part 182 is provided on the side wall of the mounting liner 18 facing the second cavity 192, and the second limiting part 123 is provided on the rear wall of the upper cover 12.

[0076] The inner liner 2 is installed in the second cavity 192 in a horizontal position. The front end face of the inner liner 2 abuts against the first limiting part 182, the rear end face of the inner liner 2 abuts against the second limiting part 123, and the circumferential wall of the inner liner 2 abuts against multiple supporting parts. The multiple supporting parts abut against both the upper and lower circumferential walls of the inner liner 2. In this way, the inner liner 2 is fully limited and fixed by the two left and right limiting parts and the multiple upper and lower supporting parts, so as to prevent the inner liner 2 from shifting during the foaming process.

[0077] During production, the inner liner 2 is first placed on the lower support 111, with the rear end face of the inner liner 2 close to the rear limiting part; then the mounting liner 18 is installed on the base plate 11, with the limiting part on the mounting liner 18 abutting against the front end face of the inner liner 2, and the rear end face of the inner liner 2 abutting against the rear limiting part; then the upper cover 12 is fastened onto the base plate 11 from top to bottom. After the upper cover 12 is installed in place, the upper support 121 abuts against the upper circumferential wall 012 of the inner liner 2.

[0078] In some embodiments of this application, the mounting liner 18 is provided with a first limiting part 182 on the side facing the inner liner 2, and the first limiting part 182 is adapted to abut against the end face of the inner liner 2. A second limiting part 123 is provided on the inner wall of the outer shell 1, and the second limiting part 123 is disposed opposite to the first limiting part 182, and the second limiting part 123 is adapted to abut against the other end face of the inner liner 2.

[0079] Specifically, refer to Figure 3 The mounting liner 18 has a circumferential rib 183 on the side facing the inner liner 2, and the circumferential rib 183 is adapted to and abuts against the end face of the inner liner 2. The circumferential rib 183 constitutes a first limiting part 182. The circumferential rib 183 helps to improve the structural strength of the mounting liner 18, and also plays a limiting role in the end face of the inner liner 2.

[0080] Reference Figure 5The inner wall of the second cavity 192 is provided with two extension plates 124. The two extension plates 124 are arranged at intervals along the width direction of the outer shell 1. The extension plates 124 are adapted to abut against the end face of the inner liner 2. A reinforcing plate 125 is provided between the two extension plates 124. The reinforcing plate 125 is provided with a notch 126.

[0081] Two spaced-apart extension plates 124 constitute the second limiting part 123 at the rear end. The side wall of the extension plate 124 that contacts the inner liner 2 is provided with an arc shape to adapt to and abut against the arc-shaped end face of the inner liner 2, thereby improving the reliability of limiting the inner liner 2.

[0082] The reinforcing plate 125 helps to improve the structural strength of the two extension plates 124. During foaming, the notch 126 allows the foaming material to flow, ensuring uniform foaming.

[0083] In some embodiments of this application, the end of the support portion is arc-shaped, and the end of the support portion is adapted to and abuts against the circumferential wall of the inner liner 2. The adaptation between the arc-shaped end of the support portion and the inner liner 2 improves the reliability of the limiting of the inner liner 2.

[0084] In some embodiments of this application, multiple support portions are arranged at intervals along the length and width directions of the outer shell 1. Specifically, the top of the outer shell 1 is provided with multiple upper support portions 121, which are arranged opposite to the central axis of the inner liner 2; the bottom of the outer shell 1 is provided with multiple lower support portions 111, which are arranged opposite to the central axis of the inner liner 2.

[0085] For example, four lower support parts 111 are provided on the base plate 11, and four upper support parts 121 are provided on the top of the upper cover 12. By arranging the multiple upper support parts 121 relative to the central axis of the inner liner 2, and arranging the multiple lower support parts 111 relative to the central axis of the inner liner 2, the multiple lower support parts 111 abut against the left and right circumferential walls of the lower part of the inner liner 2, and the multiple upper support parts 121 abut against the left and right circumferential walls of the upper part of the inner liner 2. During installation, the inner liner 2 is first placed on the lower support parts 111. Since the multiple lower support parts 111 abut against the left and right circumferential walls of the lower part of the inner liner 2, the left and right movement of the inner liner 2 can be restricted, which not only provides support for the inner liner 2, but also provides a pre-positioning function.

[0086] In some embodiments of this application, an installation liner 18 is provided in the installation cavity, the installation liner 18 divides the installation cavity into a first cavity 191 and a second cavity 192, the first cavity 191 forms an electrical compartment, the inner liner 2 is arranged laterally in the second cavity 192, and the support portion and the limiting portion are located in the second cavity 192.

[0087] The mounting liner 18 divides the mounting cavity into a first cavity 191 and a second cavity 192, enabling independent installation of the inner liner 2 and the electronic control board. The inner liner 2 is horizontally positioned within the second cavity 192. Multiple vertically arranged support parts abut and limit the upper and lower circumferential walls of the inner liner 2, while two front and rear limiting parts limit the front and rear end faces of the inner liner 2. This improves the fixed installation of the inner liner 2 within the second cavity 192 and prevents displacement of the inner liner during foaming.
