[0002] As a type of electric water heater, small kitchen water heaters are widely used in kitchens, bathrooms, and other places due to their advantages such as fast heating speed and small size. In a small kitchen water heater with integral foaming, a foaming layer is formed inside the shell using foaming tooling. The inner liner is located inside the foam layer, and the electrical chamber is formed by a separate plastic component, which is located inside the shell.

[0003] The disadvantages of this structure are: due to the presence of plastic parts in the electrical room, the thermal insulation effect of the entire small kitchen treasure is poor; after foaming, the front shell, rear shell and electrical room are easily deformed, resulting in the maintenance cover on the electrical room being difficult to install and the overall refinement of the product being unstable.

[0076] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0077] The electric water heater in this embodiment is particularly a small kitchen water heater, which includes conventional components such as a shell 300, an inner tank 200, a heating tube 610, a water inlet pipe 620, a water outlet pipe 630 and a thermostat 640, and also includes a heat preservation component 100.

[0078] Reference Figures 1 to 5 The insulation component 100 is arranged above the inner tank 200, and an electrical appliance chamber 110 is formed in the insulation component 100. The electrical appliance chamber 110 is provided with an opening 115 that passes through from top to bottom. The heating pipe 610 extends from the opening 115. The electrical appliance chamber 110 is provided with a first installation position 111 for the water inlet pipe 620, a second installation position 112 for the water outlet pipe 630, and a third installation position 113 for the thermostat 640.

[0079] In conventional technology, the electrical room is usually made of a plastic part. Since the plastic part does not have heat preservation performance, the heat preservation performance of the electric water heater will be greatly reduced.

[0080] The thermal insulation component 100 in this embodiment replaces the plastic component in the electrical room. On the basis of meeting the installation requirements of electrical components, the top-mounted thermal insulation component also helps to improve the thermal insulation performance of the electric water heater.

[0081] The first installation position 111 and the second installation position 112 are respectively through-holes that pass through the thermal insulation component 100 from top to bottom, so that the water inlet pipe 620 led out from the inner tank 200 extends through the first installation position 111 and the water outlet pipe 630 extends through the second installation position 112 to be connected to the external water pipe.

[0082] The first installation position 111 and the second installation position 112 are symmetrically arranged at the rear of the insulation component 100. The electric water heater is generally placed against a wall, so that the water inlet pipe 620 and the water outlet pipe 630 can be as close to the wall as possible for easy installation.

[0083] The first mounting position 111 and the second mounting position 112 are both connected to the opening 115, that is, the through hole where the first mounting position 111 and the second mounting position 112 are located has one side open, which is convenient for the processing of the thermal insulation component 100 on the one hand, and on the other hand is equivalent to expanding the size of the opening 115, which is convenient for the installation of other components.

[0084] The opening is located in the middle of the electrical room so that the opening and the inner tank below can be aligned vertically, making it easier to install the heating tube.

[0085] The third installation position 113 is a groove structure, and the third installation position 113 is located at the front side of the thermal insulation component 100 .

[0086] The knob 660 for controlling the temperature is arranged on the front side of the housing 300 for user convenience, and the thermostat 640 is arranged in the third installation position 113 on the front side, which can reduce the connection line between the thermostat 640 and the knob 660.

[0087] The electrical room 110 is also provided with a fourth installation position 114 for installing the indicator light 650 of the electric water heater. The fourth installation position 114 is located on the front side of the insulation component 100. The outer shell 300 is usually provided with a light-transmitting portion for the light emitted by the indicator light 650 to pass through. The front position of the indicator light 650 means that the user can observe the status of the indicator light from the front side of the electric water heater, which is convenient for the user to use.

[0088] The layout of the various installation positions in the electrical room 110 fully utilizes the existing structure of the thermal insulation component 100 and also achieves the purpose of easy installation and user convenience.

[0089] The specific shape of each position in the electrical room 110 is determined according to the size and shape of each related component.

[0090] In some embodiments of the present application, the thermal insulation component 100 also has a diversion function to improve the waterproof performance of the electric water heater.

[0091] Specifically, refer to Figure 7A first guide groove 151 is provided on the top of the insulation component 100, a second guide groove 152 is provided on the side of the insulation component 100, and a third guide groove 153 is provided at the rear of the insulation component 100. The water flowing into the first guide groove 151 then flows through the second guide groove 152 and the third guide groove 153 in sequence.

[0092] In this embodiment, the electric water heater takes a small kitchen water heater as an example. Since the small kitchen water heater is generally installed under the kitchen sink or bathroom wash basin, water droplets generally fall on the top of the shell 300. Since the thermal insulation component 100 is placed on the top, the seeping water will first contact the thermal insulation component 100. The guide structure on the thermal insulation component 100 guides the seeping water so as to guide the seeping water out, effectively preventing the seeping water from continuing to flow downward and causing adverse effects on internal structures such as the inner tank 200 and the foaming layer, thereby improving the waterproof performance of the electric water heater.

[0093] In conjunction with the guide groove structure, the outer shell 300 is provided with a water inlet hole 351 and a water outlet hole 352. The water inlet hole 351 is provided at the top of the outer shell 300, and the water outlet hole 352 is provided on the rear side of the outer shell 300. The water inlet hole 351 is opposite to the first guide groove 151. The water flowing in from the water inlet hole 351 first enters the first guide groove 151, and then flows through the second guide groove 152 and the third guide groove 153 in sequence, and then flows out from the water outlet hole 352.

[0094] The water flowing in from the water inlet 351 does not flow over a large area on the outer surface of the thermal insulation component 100, but flows along the flow path defined by the first guide groove 151, the second guide groove 152 and the third guide groove 153, thereby improving the diversion effect.

[0095] By disposing the water inlet hole 351 and the water outlet hole 352 , the water flow path completely avoids the electrical room, thereby effectively preventing the adverse effects of water seepage on the electrical components in the electrical room.

[0096] The rear water outlet 352 realizes rear side drainage, facilitates the collection and treatment of drainage, and does not affect the user's hygiene.

[0097] The top of the thermal insulation component 100 has an arcuate portion 140 , which intersects with the side wall of the thermal insulation component 100 . A first guide groove 151 is provided on the arcuate portion 140 to facilitate water falling into the first guide groove 151 to flow into the second guide groove 152 on the side.

[0098] The outer surface of the housing 300 generally adopts a rounded corner design at the edges and corners, and the arc surface portion 140 also avoids interference with the rounded corner structure of the housing 300.

[0099] Reference Figure 6 and Figure 7The left and / or right side surface of the heat preservation piece 100 has a first inwardly recessed surface 131 and a circumferential side end surface 120, the first inwardly recessed surface 131 is above and inwardly recessed from the circumferential side end surface 120, and a second flow guide groove 152 is formed between the first inwardly recessed surface 131 and the inner surface of the shell 300.

[0100] The rear side surface of the heat preservation piece 100 has a second inwardly recessed surface 132 and a circumferential side end surface 120, the second inwardly recessed surface 132 is above and inwardly recessed from the circumferential side end surface 120, and a third flow guide groove 153 is formed between the second inwardly recessed surface 132 and the inner surface of the shell 300.

[0101] The inner surface of the shell 300 actually acts as a side wall of the second flow guide groove 152 and the third flow guide groove 153, achieving water blocking and flow guiding.

[0102] In actual processing of the heat preservation piece 100, only the inwardly recessed surface needs to be processed on the circumferential side surface, simplifying the processing of the heat preservation piece.

[0103] The first inwardly recessed surface 131 is provided with a flow guide step 154, the flow guide step 154 extends obliquely downward from the front side to the rear side of the heat preservation piece 100, the flow guide step 154 plays a role in shunting water flowing down from the first flow guide groove 151, improving the flow guiding effect of the side surface of the heat preservation piece 100.

[0104] The second flow guide groove 152 and the flow guide step 154 are respectively provided with a stop step 155 at one end close to the front side of the heat preservation piece 100, avoiding water seepage from flowing to the front side of the shell 300, but flowing to the rear side water outlet hole 352 for discharge.

[0105] In some embodiments of the present application, the bottom of the shell 300 is provided with a plurality of feet 380, the height of the feet 380 located on the front side is higher than the height of the feet 380 located on the rear side, and the design of the feet being higher in front and lower in rear is to cooperate with the flow guiding structure, so as to further improve the flow guiding effect and ensure that the seepage water is collected from front to rear to the rear side water outlet hole 352.

[0106] In some embodiments of the present application, referring to Figure 1 and Figure 5 , the top of the shell 300 is provided with a maintenance opening 330, and the maintenance opening 330 is provided with a maintenance cover plate 400.

[0107] The electric water heater in the embodiment is of a top maintenance type, and the heat preservation piece 100 at the top can be seen by opening the maintenance cover plate 400.

[0108] Since the insulation part 100 is provided with an electrical room 110, the electrical room 110 is opposite to the maintenance port 330. Thus, the electrical components in the electrical room 110 can be repaired by opening the maintenance cover 400, without having to remove the outer shell to repair the electrical components as in the prior art, which greatly improves the convenience of maintenance.

[0109] The maintenance cover 400 is provided with a first opening 431 for the water inlet pipe 620 to extend out, and a second opening 432 for the water outlet pipe 630 to extend out, so that there is no need to open a pipe outlet on the outer shell 300. As can be seen from the figure, the maintenance cover 400 covers most of the area of ​​the top of the outer shell 300. In this way, when the maintenance cover 400 is removed, the entire electrical room 110 can be completely exposed, which is convenient for the maintenance of internal components.

[0110] A water receiving trough 340 is provided on the housing 300 at the maintenance opening 330 . The water receiving trough 340 surrounds the maintenance opening 330 , and the maintenance cover 400 is in close contact with the outer wall of the water receiving trough 340 .

[0111] During long-term use of the electric water heater, water may seep into the gap between the maintenance cover 400 and the water receiving tank 340 . The water receiving tank 340 receives the seeped water to prevent it from directly dripping into the electrical room 110 .

[0112] This embodiment combines the water receiving trough 340 with the guide structure on the insulation component 100. The water inlet hole 351 is provided in the water receiving trough 340. The water that penetrates into the water receiving trough 340 through the gap at the maintenance cover 400 flows directly into the first guide trough 151 through the water inlet hole 351, and then flows through the second guide trough 152 and the third guide trough 153 in sequence, and is finally discharged from the water outlet hole 352, thereby realizing a complete water path for receiving, guiding and draining water.

[0113] Reference Figure 5 The housing 300 is provided with a connecting frame 360 ​​and a plurality of first clamping portions 370 at the maintenance opening 330, and the connecting frame 360 ​​is provided with a first screw hole 361. Figure 11 A second clamping portion 410 and a second screw hole 420 are correspondingly provided on the maintenance cover 400 .

[0114] Screws are passed through the first screw hole 361 and the second screw hole 420 , and the first clamping portion 370 is clamped with the second clamping portion 410 to achieve a fastened connection between the maintenance cover 400 and the housing 300 .

[0115] The maintenance cover 400 can be connected to the housing 300 by only one screw, and the number of screws is small, which greatly reduces the disassembly and assembly process and time.

[0116] Furthermore, through the snap-fitting of the first snap-fitting portion 370 and the second snap-fitting portion 410 , the fastening structure between the maintenance cover 400 and the housing 300 is more reliable.

[0117] In this embodiment, the first engaging portion 370 is a protruding structure facing the maintenance opening 330 , and the second engaging portion 340 is a claw, and the protruding structure is adapted to engage with the groove structure on the claw.

[0118] In some embodiments of the present application, the housing 300 includes a front shell 310 and a rear shell 320 .

[0119] Reference Figure 10 , a plurality of third screw holes 311 are respectively provided on the left and right sides and the bottom side of the front shell 310, and a third clamping portion 312 is also provided on the bottom side of the front shell 310; Figure 9 A plurality of fourth screw holes 321 are respectively provided on the left and right sides and the bottom side of the rear shell 320, and a fourth clamping portion 322 is also provided on the bottom side of the rear shell 320; screws are passed through the third screw holes 311 and the fourth screw holes 321, and the third clamping portion 312 is clamped with the fourth clamping portion 322 to achieve a fastened connection between the front shell 310 and the rear shell 320.

[0120] In this embodiment, the third clamping portion 312 is a claw structure, and the fourth clamping portion 322 is a hole structure. During the installation process of the front shell 310 and the rear shell 320, the front shell 310 and the rear shell 320 are pre-positioned by the clamping between the third clamping portion 312 and the fourth clamping portion 322, which facilitates the subsequent installation of screws.

[0121] Reference Figure 9 A groove portion 324 is provided on the rear shell 320, and the fourth screw hole 321 is located in the groove portion 324. The screws are driven in from the rear side of the outer shell 300, and the screws are not visible from the front side of the electric water heater, which makes the appearance more beautiful. The groove portion 324 shields and waterproofs the screws, preventing the screws from rusting after being exposed to water for a long time, resulting in the situation that they cannot be disassembled.

[0122] A first notch 311 is provided on the top of the front shell 310 , and a second notch 323 is provided on the top of the rear shell 320 . After the front shell 310 and the rear shell 320 are connected, the first notch 313 and the second notch 323 are aligned to form a maintenance port 330 .

[0123] In this embodiment, a foaming cavity 500 is formed between the outer shell 300 , the bottom end surface of the heat-insulating element 100 , and the inner liner 200 located below the heat-insulating element 100 .

[0124] In the existing technology, the foaming cavity is usually formed by the gap between the outer shell and the inner liner. The foaming volume is large and the foaming pressure is high. During the foaming process, the foaming material is prone to overflow, and the inner liner and other components are easily displaced by the foaming pressure, affecting the refined stability of the product after processing and molding, and making it inconvenient to position and install subsequent components.

[0125] In the present application, through the setting of the insulation part 100, the foaming cavity 500 is formed by the gap between the outer shell 300, the bottom end surface of the insulation part 100, and the inner liner 200 located below the insulation part 100. The foaming volume is small and the foaming pressure is small, which can effectively avoid the overflow of foaming material and the position displacement of components such as the inner liner due to the foaming pressure, thereby improving the refined stability of the product and facilitating the positioning and installation of subsequent products.

[0126] While forming the foaming cavity, the heat-insulating element 100 also has its own heat-insulating performance, which helps to improve the heat-insulating performance of the electric water heater.

[0127] The upper part of the inner liner 200 is embedded in the thermal insulation component 100, so that the thermal insulation component 100 does not occupy additional space in the outer shell 300, which is conducive to the compact design of the inner components of the outer shell 300 and the realization of the miniaturization design purpose of the product; at the same time, the thermal insulation component 100 also plays a positioning and supporting role for the inner liner 200, further avoiding the position displacement of the inner liner 200 during the foaming process.

[0128] The design of this embodiment in which the insulation component 100 is arranged inside the outer shell 300 and on the inner tank 200 overturns the conventional design concept of existing electric water heaters. From the perspective of reducing the foaming volume and foaming pressure, it improves the refined stability of product processing and molding; at the same time, it takes into account the advantages of thermal insulation and compact design.

[0129] By utilizing the easy processability of the thermal insulation component 100, the thermal insulation component 100 can be easily differentiated in design for shells and inner tanks of different sizes and shapes, making it more adaptable and applicable to different types of electric water heaters.

[0130] In actual processing, it is difficult to ensure an absolutely seamless installation between the insulation component 100 and the inner liner 200, and between the insulation component 100 and the outer shell 300. Even if a small amount of foaming material overflows, the foaming material will cool and take shape after flowing along the insulation component 100 for a short distance. However, due to the positioning and supporting effect of the insulation component 100 on the inner liner 200, the overflow of these small amounts of foaming material will not affect the positional deviation of the inner liner 200. On the contrary, these small amounts of foaming material will further improve the fit stability between the insulation component 100 and the outer shell 300, as well as the inner liner 200 after cooling and taking shape.

[0131] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0132] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
