[0061] The horizontal kitchen treasure is a water heater which uses electric energy as the main energy material. After being powered on, the high-temperature heat generated directly heats the water stored in the horizontal kitchen treasure to achieve the purpose of preparing hot water.

[0062] The horizontal kitchen treasure generally includes a water tank, an electric heating component, and an electric control board, etc. Among them, the water tank forms a water storage cavity to store water to be heated, the electric heating component is inserted into the water storage cavity formed by the water tank, and the electric control board is used to control the on-off operation of the electric heating component to heat the water in the water tank to a set temperature.

[0063] For the water tank of the horizontal kitchen treasure, the water tank generally includes an outer shell and an inner container, and a heat preservation layer is formed between the outer shell and the inner container. Among them, the outer shell is generally made of plastic material to meet the design requirements of diversified modeling; the inner container can be made of a metal container body or a plastic container body according to needs.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Example 1, as Figures 1-14 As shown, this embodiment provides a horizontal kitchen water heater, including:

[0071] The outer casing 1 has a mounting support surface 19 formed at its bottom;

[0072] Inner liner 2, which is disposed in the outer shell 1;

[0073] An electric heating element 3 is disposed in the inner liner 2;

[0074] The inlet and outlet pipe assembly 4 includes an inlet pipe 41 and an outlet pipe 42, which are sealed through the inner liner 2.

[0075] Specifically, in one embodiment of this application, a horizontal kitchen water heater has an installation support surface 19 formed at the bottom of its outer shell 1. When installed in a user's home, it is placed in a cabinet through the installation support surface 19 to complete the installation without the need for hanging.

[0076] In order to reduce the overall height of the horizontal kitchen god and increase the volume of the inner container 2, the installation method of the inner container 2 and the inlet and outlet pipe group 4 can be improved as follows.

[0077] The inner container 2 is arranged transversely in the outer shell 1; the electric heating pipe 3 extends transversely and is arranged in the inner container 2; the water inlet end of the water inlet pipe 41 is located in the inner container 2 and arranged in the lower area of the inner container 2, and the water outlet end of the water outlet pipe 42 is located in the inner container 2 and arranged in the upper area of the inner container 2; wherein the water inlet end of the water inlet pipe 41 and the water outlet end of the water outlet pipe 42 respectively extend to the outside of the outer shell 1 and extend transversely.

[0078] Specifically, the water inlet pipe 41 and the water outlet pipe 42 extend transversely from the outer shell 1 to the outside of the outer shell 1, the water inlet end of the water inlet pipe 41 is in a transversely extending state to facilitate connection with the water pipe in the cabinet without occupying height space, and the water outlet end of the water outlet pipe 42 is also in a transversely extending state to facilitate connection with the water pipe in the cabinet without occupying height space.

[0079] In this way, on the one hand, for the horizontal kitchen god as a whole, as long as the top height of the outer shell 1 meets the installation requirements, the horizontal kitchen god can be installed in the cabinet, without being limited by the connection pipe 45 of the water inlet pipe 41 and the water outlet pipe 42, which is convenient for installation and has better versatility; on the other hand, since the overall height of the outer shell 1 is not limited by the height position of the water inlet pipe 41 and the water outlet pipe 42, the diameter of the inner container 2 in the outer shell 1 can be further increased, and the volume of the inner container 2 can be effectively increased without changing the length of the outer shell 1.

[0080] Since the horizontal kitchen god is installed in the cabinet in the user's home, the height of the outer shell 1 is 200mm-500mm to distinguish from the conventional wall-mounted horizontal kitchen god.

[0081] By arranging the inner container 2 transversely and extending the water inlet end of the water inlet pipe 41 and the water outlet end of the water outlet pipe 42 to the outside of the outer shell 1, the height space in the cabinet can not be occupied during connection with the external pipeline, thereby effectively increasing the diameter of the inner container 2. Under normal circumstances, the height space in the cabinet is limited but has sufficient depth to meet the installation requirements of the horizontal kitchen god, so that the inner container 2 of the horizontal kitchen god has sufficient length. Under the condition that the length of the inner container 2 is the same, increasing the diameter of the inner container 2 can effectively increase the volume of the kitchen god to improve the user experience.

[0082] In an embodiment, in order to improve the hot water output rate of the horizontal kitchen appliance, the water outlet pipe 42 is bent upward at the water inlet end to form a first bend, and the opening of the first bend is close to the top wall of the inner container 2.

[0083] Specifically, the water outlet pipe 42 is bent at the water inlet end to form a first bend, and the opening of the first bend is located at the top of the inner container 2. In this way, during the output of hot water, the hot water can be output from the top of the inner container 2 to improve the hot water output rate.

[0084] At the same time, since the water outlet pipe 42 is bent to form a first bend, the water inlet position of the water outlet pipe 42 can be arranged at the top of the inner container 2 to the maximum extent. In this way, the water outlet pipe 42 can not be arranged close to the upper wall of the inner container 2, thereby solving the technical problem of low welding quality caused by the increase of the intersection line and burrs between the water outlet pipe 42 and the inner container 2.

[0085] Similarly, the outer lining pipe 43 can also be used to meet the requirement of improving the hot water output rate. Specifically, the outer lining pipe 43 is located in the inner container 2, and the free end of the outer lining pipe 43 is bent upward to form a second bend 431, and the opening of the second bend 431 is close to the top wall of the inner container 2.

[0086] Specifically, the outer lining pipe 43 is sleeved outside the water outlet pipe 42, and the free end of the outer lining pipe 43 is bent to form a second bend 431, and the opening of the second bend 431 is close to the top wall of the inner container 2. In this way, during the output of hot water through the water outlet pipe 42, the hot water at the top of the inner container 2 flows into the outer lining pipe 43 through the second bend 431, and then flows into the water outlet pipe 42 through the water inlet end of the water outlet pipe 42 for delivery and output to the outside of the outer shell 1.

[0087] At the same time, since the outer lining pipe 43 is bent to form a second bend 431, the water inlet position of the second bend 431 can be arranged at the top of the inner container 2 to the maximum extent. In this way, the water outlet pipe 42 can not be arranged close to the upper wall of the inner container 2, thereby solving the technical problem of low welding quality caused by the increase of the intersection line and burrs between the water outlet pipe 42 and the inner container 2.

[0088] Further, in order to facilitate the installation of the outer lining pipe 43, the outer end of the outer lining pipe 43 is provided with an outward flanging structure 432, which is lapped on the outer side of the inner container 2.

[0089] Specifically, during assembly, the outer lining pipe 43 is first inserted into the inner container 2, and after the outer lining pipe 43 is inserted in place, the outward flanging structure 432 is positioned on the outer surface of the inner container 2 to meet the requirement of accurate installation of the outer lining pipe 43.

[0090] In an embodiment of the present application, one end of the inner container 2 is provided with a flange plate 21, and the mounting end of the electric heating pipe 3 is provided with a mounting seat 33, which is arranged on the flange plate 21;

[0091] The other end of the inner container 2 is provided with a first mounting pipe 22 and a second mounting pipe 23, the first mounting pipe 22 is arranged above the second mounting pipe 23, and the first mounting pipe 22 and the second mounting pipe 23 are respectively welded on the inner container 2 and respectively communicate with the inner container 2; the water outlet pipe 42 is sealingly inserted into the first mounting pipe 22, and the water inlet pipe 41 is sealingly inserted into the second mounting pipe 23.

[0092] Specifically, in order to facilitate the installation of the inlet and outlet pipe group 4 and the electric heating pipe 3, one end of the inner container 2 is provided with a flange plate 21, and the flange plate 21 meets the installation requirements of the electric heating pipe 3. The other end of the inner container 2 is provided with a first mounting pipe 22 and a second mounting pipe 23, which are welded on the inner container 2. In this way, the installation requirements of the water inlet pipe 41 and the water outlet pipe 42 can be met.

[0093] In another embodiment of the present application, the shell 1 is further provided with two foamed supports, the two foamed supports are oppositely arranged and vertically arranged in the shell 1, and the side wall of the foamed support forms a concave surface, which matches the contour of the end of the inner container 2;

[0094] The inner container 2 is clamped between the two foamed supports, and a foamed layer is arranged between the shell 1 and the inner container 2.

[0095] Specifically, since the inner container 2 of the horizontal kitchen is arranged transversely, in order to provide good support and heat preservation for the inner container 2, foamed supports are arranged at the two ends of the inner container 2 respectively. The concave surface formed by the foamed support can match the end surface of the corresponding end of the inner container 2, so that the end of the inner container 2 can be tightly attached to the concave surface of the foamed support, thereby improving the assembly reliability. In addition, the foamed support can also provide heat preservation at the two ends of the inner container 2.

[0096] After the ends of the inner container 2 are supported and provided with heat preservation by the foamed supports, in order to improve the overall heat preservation performance of the inner container 2, foamed material is filled between the two foamed supports, and the foamed material forms a foamed layer between the inner container 2 and the shell 1 to improve the heat preservation performance of the inner container 2.

[0097] Further, since the structure of the two ends of the inner container 2 is different, in order to facilitate the assembly, the two foamed supports are divided into a first foamed support 13 and a second foamed support 14.

[0098] The first foaming piece 13 is provided with a first installation opening 131, and the flange plate 21 provided on the inner container 2 passes through the first installation opening 131.

[0099] The second foaming piece 14 is provided with a second installation opening 141 and a third installation opening 142, the second installation opening 141 is arranged above the third installation opening 142, the water outlet pipe 42 passes through the second installation opening 141, and the water inlet pipe 41 passes through the third installation opening 142.

[0100] Specifically, the end of the inner container 2 provided with the flange plate 21 is assembled to the first foaming piece 13, and the flange plate 21 is used for installing the electric heating pipe 3. In order to meet the power supply requirement of the electric heating pipe 3, the first installation opening 131 is arranged on the first foaming piece 13, and the flange plate 21 passes through the first installation opening 131 to facilitate circuit wiring.

[0101] For the other end of the inner container 2, the water inlet pipe 41 and the water outlet pipe 42 need to be installed, therefore, the second installation opening 141 and the third installation opening 142 are arranged on the second foaming piece 14, the first installation pipe 22 passes through the second installation opening 141, and the second installation pipe 23 passes through the third installation opening 142.

[0102] Further, in order to improve the installation accuracy of the foaming support piece and reduce the overflow leakage of the foaming material, the bottom of the shell 1 is provided with a first blocking rib 111 and a second blocking rib 112.

[0103] The first foaming piece 13 is arranged at the back side of the first blocking rib 111, and the second foaming piece 14 is arranged at the back side of the second blocking rib.

[0104] Specifically, the first blocking rib 111 and the second blocking rib 112 can limit the positions of the first foaming piece 13 and the second foaming piece 14, so as to ensure that the first foaming piece 13 and the second foaming piece 14 are installed in place. In the foaming process, the first blocking rib 111 and the bottom of the first foaming piece 13 form an overlapping area, and similarly, the second blocking rib 112 and the bottom of the second foaming piece 14 form an overlapping area, and the overlapping area is used to prevent the overflow of the foaming material.

[0105] Still further, in order to improve the installation reliability of the inner container 2 and ensure that the position of the inner container 2 remains stable during the foaming process, the bottom of the inner container 2 is further provided with an installation fixing seat, and the installation fixing seat is fixedly connected to the shell 1.

[0106] Specifically, during the assembling process, on one hand, the two end portions of the inner container 2 are supported by the first foaming piece 13 and the second foaming piece 14, and on the other hand, the mounting fixing seat arranged at the bottom portion of the inner container 2 can be directly fixed and mounted on the bottom plate 11 of the outer shell 1 by means of screws or the like, so that the position between the inner container 2 and the bottom plate 11 of the outer shell 1 is stable and immovable. In this way, during the foaming process, the force generated by the foaming material between the inner container 2 and the outer shell 1 will not affect the position of the inner container 2, thereby improving the quality of the product.

[0107] The mounting fixing seat can be fixedly connected to the inner container 2 by welding.

[0108] Further, in order to improve the assembling accuracy and the convenience of assembly, the bottom portion of the outer shell 1 is further provided with a positioning groove 113, and the mounting fixing seat is located in the positioning groove 113.

[0109] Specifically, the bottom plate 11 of the outer shell 1 is further provided with a mounting groove, and when the inner container 2 is assembled to the bottom plate 11 of the outer shell 1, the mounting groove on the bottom plate 11 can accommodate the mounting fixing seat at the bottom portion of the inner container 2, so as to realize pre-assembly by cooperation of the mounting fixing seat and the mounting groove, thereby improving the assembling accuracy and the convenience of assembly.

[0110] In some embodiments of the present application, the water inlet end portion of the water inlet pipe 41 and the water outlet end portion of the water outlet pipe 42 are arranged at various positions extending out of the outer shell 1, for example:

[0111] The water inlet end portion of the water inlet pipe 41 and the water outlet end portion of the water outlet pipe 42 are arranged at the rear end portion of the outer shell 1. Alternatively, the water inlet end portion of the water inlet pipe 41 and the water outlet end portion of the water outlet pipe 42 are arranged at the side portion of the outer shell 1.

[0112] Specifically, the water inlet end portion of the water inlet pipe 41 and the water outlet end portion of the water outlet pipe 42 are arranged at the rear end portion of the outer shell 1.

[0113] The water inlet end portion of the water inlet pipe 41 and the water outlet end portion of the water outlet pipe 42 are arranged at the rear end portion of the outer shell 1, and when the water pipe is connected, the water pipe in the user's home is connected at the rear portion of the outer shell 1. After connection, the pipeline is arranged at the rear portion of the outer shell 1 and does not occupy the space at the top portion of the outer shell 1.

[0114] In another embodiment, in order to facilitate the user to operate the horizontal kitchen appliance to adjust the temperature, and to facilitate the maintenance of the electrical components by the later operator, the front end portion of the outer shell 1 is provided with an electrical appliance chamber, and the electrical control panel 15 is arranged in the electrical appliance chamber.

[0147] In order to improve the use safety and reliability, the electrical appliance chamber is arranged at the front end of the shell 1, and the water inlet end of the water inlet pipe 41 and the water outlet end of the water outlet pipe 42 are arranged at the rear end of the shell 1.

[0148] As shown in Figures 1-7 、 Figure 14 By separating the electrical appliance chamber and the water inlet and outlet pipe 42 from each other, the electrical appliance chamber is arranged at the front end of the shell 1 for user operation and use, and the water inlet and outlet pipe 42 is completely separated from the electrical appliance chamber, so as to avoid the damage of the electrical devices in the electrical appliance chamber caused by the leakage of the end connecting position of the water inlet and outlet pipe 42, and further improve the use reliability of the kitchen treasure.

[0149] Since the electrical appliance chamber is arranged at the front end of the shell 1, the power supply cable needs to be connected with the electrical control panel 15 in the electrical appliance chamber, in order to realize hidden wiring, the lower surface of the bottom plate 11 is provided with a wiring groove 115 extending from front to back to the rear side of the shell 1;

[0150] The bottom plate 11 is further provided with a wire outlet hole 116 communicating with the wiring groove 115; the power supply cable connected with the electrical control panel 15 passes through the wire outlet hole 116 and extends out of the rear side of the shell 1 through the wiring groove 115.

[0153] Further, the bottom plate 11 is further provided with a wire routing pipe 117 vertically arranged and communicating with the wire outlet hole 116, and the power supply cable passes through the wire routing pipe 117.

[0154] Specifically, since the horizontal kitchen appliance is placed in the cabinet, when the water basin above the cabinet overflows and causes water to accumulate on the bottom of the cabinet where the shell 1 is located, the water will enter the wire outlet hole 116 from the wire routing groove 115. Since the upper surface of the bottom plate 11 is further provided with a vertically arranged wire routing pipe 117, the height of the wire routing pipe 117 is higher than the upper surface of the bottom plate 11. In this way, even if there is water accumulation in the cabinet, the water level height will not be higher than the top pipe opening height of the wire routing pipe 117, thereby avoiding the water from entering the electrical appliance chamber through the wire outlet hole 116, and further improving the use reliability.

[0157] In one embodiment, the two sides of the bottom plate 11 are further provided with a carrying and pulling portion 119, and the carrying and pulling portion 119 is an upwardly concave structure formed on the bottom surface of the bottom plate 11.

[0158] Specifically, in order to facilitate the operation personnel to carry the horizontal kitchen appliance, a carrying and pulling portion 119 can be further arranged on the bottom plate 11, and the carrying and pulling portion 119 is formed on the bottom plate 11 and concave upwards. During the carrying process, the user inserts his hand into the carrying and pulling portion 119, and then the horizontal kitchen appliance can be lifted and moved.

[0159] In order to reduce the overall height of the horizontal kitchen appliance while meeting the requirement of efficient heating of the electric heating tube 3 in the inner container 2, the electric heating tube 3 is improved in structure and installation position as follows.

[0160] As shown in FIG. 1, the electric heating tube 3 comprises a straight supporting section 31 and a curved heating section 32, and the curved heating section 32 is connected to the straight supporting section 31. Figures 10-13

The straight supporting section 31 can support the curved heating section 32. The curved heating section 32 is arranged at the lower part of the inner container 2 by virtue of its curved structure, so as to heat the water from the bottom of the inner container 2 to improve the heating efficiency of the water in the inner container 2.

[0163] In addition, in order to avoid interference with the water inlet pipe 41 at the bottom, the curved heating section 32 is arranged offset to one side of the inner container 2. In this way, although the electric heating tube 3 and the water inlet pipe 41 are both arranged transversely in the inner container 2, the offset installation of the electric heating tube 3 can avoid installation interference and ensure the heating efficiency.

[0164] Further, in order to improve the hot water output rate and realize instant water supply, the electric heating tube 3 further comprises an extension heating section (not shown), which extends to the top of the inner container 2 and is arranged close to the water outlet pipe 42.

[0165] Specifically, the electric heating tube 3 can further be provided with an extension heating section extending upwards and arranged around the water outlet pipe 42, which can heat the water entering the water outlet pipe 42 and the water around the water outlet pipe 42, so as to realize instant water supply.

Alternatively, the extension heating section can be independent of the curved heating section 32. The extension heating section can be a separate heating pipe body, and the end of the extension heating section is fixedly installed on the mounting seat 33.

[0168] In addition, the extension heating section is also wound around the periphery of the water outlet pipe 42.

[0169] Specifically, the extension heating section can be wound around the periphery of the water outlet pipe 42 to increase the overall length of the extension heating section, thereby improving the heating efficiency and heating speed.

[0170] In some embodiments of the present application, a heat insulation pad 24 is further arranged between the inner container 2 and the foamed support.

[0171] Specifically, since the inner container 2 is arranged transversely, the overall height of the inner container 2 is small, and the foamed support arranged at the end of the inner container 2 is tightly attached to the inner container 2. When the inner container 2 is subjected to a dry burning test, the temperature at the top of the inner container 2 rises rapidly, and the temperature in the inner container 2 will reach 200℃ in a short time. The foamed support is usually made of foam and is easily affected by high temperature and melts.

[0172] The heat insulation pad 24 is made of ABS plastic or polystyrene and the like, has good mechanical properties and structural stability, and better meets the requirements of ready installation. Herein, the material of the heat insulation pad 24 is not limited.

[0173] Therefore, the heat insulation pad 24 is arranged at at least one end of the inner container 2 to protect the foamed support.

[0174] Usually, the electric heating pipe 3 arranged at the flange plate 21 of the inner container 2 is a straight support section 31, and the heat generation thereof is smaller than that of the curved heating section 32. The curved heating section 32 is close to the positions where the water inlet pipe 41 and the water outlet pipe 42 are installed and fixed on the inner container 2, and the heat generation of the curved heating section 32 is large. Therefore, the heat insulation pad 24 is arranged at least between the inner container 2 and the second foamed support 14.

[0175] Further, in order to facilitate the installation and positioning of the heat insulation pad 24, the heat insulation pad 24 can be bonded to the outer surface of the inner container 2.

When the inner container 2 is assembled between the first foaming piece 13 and the second foaming piece 14, the positioning part 241 of the heat insulation pad 24 is matched with the positioning matching part 143 on the second foaming piece 14 to position the heat insulation pad 24, so as to ensure that the heat insulation pad 24 can be accurately positioned, thereby playing a good heat insulation effect on the position of the inner container 2 which needs to be insulated, and playing a heat insulation protection effect on the second foaming piece 14.

[0178] Specifically, the positioning part 241 can be a positioning protrusion, and the positioning matching part 143 is a positioning groove formed on the second foaming piece 14. The positioning protrusion is inserted into the positioning groove, so that the heat insulation pad 24 can be positioned and installed.

[0179] Alternatively, the heat insulation pad 24 is provided with a through hole (not marked), and the inner container is provided with a water inlet pipe 41 and a water outlet pipe 42. The water inlet pipe 41 or the water outlet pipe 42 is inserted into the through hole.

[0180] Specifically, the heat insulation pad 24 is positioned and installed by cooperating with the water inlet pipe 41 or the water outlet pipe 42 through the through hole on the heat insulation pad 24.

[0181] Alternatively, the heat insulation pad 24 is adhered to the inner container 2.

[0182] Specifically, the heat insulation pad 24 is bonded to the inner container 2, so that the connection between the two is more reliable.

[0183] Preferably, the heat insulation pad 24 covers the recessed surface of the second foaming piece 14, so that the second foaming piece 14 is completely isolated from the inner container 2.

[0184] In another embodiment of the present application, the horizontal kitchen treasure further comprises a temperature sensing assembly, the temperature sensing assembly comprising a temperature measuring pipe 26 and a temperature sensor, the temperature measuring pipe being arranged at the end of the inner container 2.

[0186] Specifically, the temperature measuring pipe can be fixed on the mounting seat 33, so as to be supported and installed by the mounting seat 33.

[0187] Alternatively, the temperature measuring pipe is directly fixed on the inner container 2 and is offset above the flange plate 21. In this way, during the dry burning test, the temperature measuring pipe is closer to the top of the inner container 2, so that the temperature sensor can more timely and effectively detect the temperature of the top of the inner container 2.

[0188] In another embodiment of the present application, in order to realize constant temperature water outlet, a constant temperature valve 44 can also be configured. Specifically, the water outlet end of the water outlet pipe 42 is also provided with the constant temperature valve 44, and the water inlet end of the water inlet pipe 41 is also provided with a three-way pipe; the constant temperature valve 44 and the three-way pipe are also provided with a connecting pipe 45.
