Description

BACKGROUND

1. Technical Field

The present invention relates to the technical field of water heaters, specifically to a water heater.

2. Background Information

In modern household life, the kitchen, as an important place for daily cooking, is increasingly valued for its comfort and convenience. Especially in the cold season, the direct use of cold water for washing or cooking not only affects the operation experience but may have unhealthy effects. Therefore, most modern kitchens are equipped with water heaters or hot water faucets to provide warm and comfortable hot water. Considering safety and environmental protection, electric water heaters, due to advantages such as no emission and easy control, have become the first choice for hot water supply in the kitchen. However, given the limited kitchen space, small electric water heaters (commonly known as “small kitchen treasures”) are popular for their compact design, allowing for efficient use of space and meeting daily hot water needs.

While enjoying the convenience brought by electric water heaters, the users always first consider their safety. Particularly, preventing the risk of electric shock caused by electric leakage of electrical equipment is an important aspect that cannot be ignored in water heater design. Conventionally, to enhance electrical safety, the water outlet of the water heater is externally connected to an anti-electric wall apparatus, and this apparatus uses the water resistance characteristic to effectively limit leakage current, protecting the users from being injured by electric shock. However, it is worth noting that many water heaters on the market are not pre-mounted with anti-electric walls at the factory but require users to mount them on their own. This kind of design, although providing flexibility, also brings challenges: as the anti-electric wall and the water heater are mostly connected by threads, improper mounting or loose connection is likely to cause a water leakage problem, affecting the usage effect and potentially causing short circuit, electric shock, and other safety hazards, thus posing a potential threat to home safety.

DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERRED EMBODIMENTS

The following description is essentially exemplary and is not intended to limit the present disclosure, application, and use. It should be understood that in all these drawings, the same or similar numeral references indicate the same or similar parts and features. The drawings only schematically show the conceptions and principles of the implementations of the present disclosure and do not necessarily show the specific dimensions and proportions of each implementation of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the implementations of the present disclosure.

Referring to FIGS. 1 to 16, the present invention provides an embodiment:

A water heater is provided, including a shell 100 and an anti-electric wall 104. A heater 102 is disposed in the shell 100, two ends of the heater 102 communicate with connecting pipes 103, and ends of the connecting pipes 103 respectively communicate with a water outlet pipe 139 and a water inlet pipe 140. The anti-electric wall 104 is disposed inside or outside the shell 100, and the anti-electric wall 104 includes a mounting shell. The mounting shell and the water inlet pipe 140 are arranged integrally, and a folded water flow channel is disposed in the mounting shell, where a water flow, after heated by the heater 102, enters the folded water flow channel and then flows out.

In this embodiment, as the anti-electric wall 104 is integrated with the connecting pipe 103 on the heater 102, during product production, the anti-electric wall 104 is directly mounted on the water heater, such that the user does not need to additionally connect the anti-electric wall 104 during use. This can avoid potential leakage at the joint between the anti-electric wall 104 and the heater 102 during the use of the water heater. When the anti-electric wall 104 is mounted inside the shell 100, the overall appearance of the water heater product is tidier. When the anti-electric wall 104 is mounted outside the shell 100, it is convenient for the user to directly see the setting of the anti-electric wall 104. The heater 102 is mounted with an overheat protector 106 for monitoring temperature of the heater 102. A resetting button 107 is provided on the overheat protector 106. When the temperature of the heater 102 is excessively high, the resetting button 107 pops out to power off the heater 102. The shell 100 is provided with an insertion hole 120, and the insertion hole 120 corresponds in position to the resetting button 107. After the heater 102 cools down and is restored, a non-metallic object is inserted into the insertion hole 120 to press the resetting button 107 for resetting. When the temperature of the heater 102 is too high, the overheat protector 106 detects that the temperature change of the heater 102 exceeds the limit temperature, and the resetting button 107 on the overheat protector 106 pops out, causing the heater 102 to power off and stop working in a short time, so as to ensure the use safety. However, because the resetting button 107 is located in the shell 100, professional personnel are needed to disassemble the shell 100 to restart the overheat protector 106. Therefore, the insertion hole 120 is provided in the shell 100, allowing the user to restart the overheat protector 106 without disassembling the machine. A resetting shell 108 is integrally disposed in the shell 100, and a resetting cavity 118 is provided in the resetting shell 108. The insertion hole 120 communicates with the resetting cavity 118, and the resetting button 107 extends into the resetting cavity 118. When the resetting button 107 needs to be pressed for resetting, the non-metallic object is used to extend into the resetting cavity 118 to toggle the resetting button 107. The provision of the resetting shell 108 in the shell 100 can isolate the resetting button 107 from other parts in the shell 100, avoiding that an object goes into the shell 100 and damages other parts in the shell 100 during the process of toggling the resetting button 107 for resetting or the use of the water heater, and that the user suffers an electric shock risk due to contact with the other parts in the shell 100. A water flow rotor 110 is disposed in the connecting pipe 103 of the water outlet pipe 139 and/or the water inlet pipe 140. A mounting groove 111 is provided on a pipe wall of the water outlet pipe 139, and a hall sensor 112 is inserted into the mounting groove 111. A control assembly 101 is mounted in the shell 100, and the control assembly 101 is electrically connected to the heater 102 and the hall sensor 112. A magnet is provided in the water flow rotor 110. The hall sensor 112 monitors the rotational speed of the water flow rotor 110 to determine the water flow capacity. As the mounting groove 111 is provided on the wall of the connecting pipe 103, the hall sensor 112 only needs to be inserted into the mounting groove 111 during the production and assembly of the water heater, making the operation simple and convenient.

Further, the shell 100 is provided with a through hole corresponding in position to a flow regulating valve 121, and a water separator 125 is disposed at the through hole. A rotary cover 122 is disposed outside the shell 100, and the rotary cover 122 sleeves the water separator 125 and is connected to a control lever 124 of the corresponding flow regulating valve 121. A limiting rib 126 is disposed on the water separator 125, and an adjustment portion is disposed on the rotary cover 122. In a process of adjusting the rotary cover 122 to rotate forward or backward, when the adjustment portion abuts against the limiting rib 126, the flow regulating valve 121 is located at a position of a set maximum water flow capacity or a set minimum water flow capacity. The water separator 125 includes a water separating ring arranged at the through hole and extending outwards. The rotary cover 122 sleeves the water separating ring, the rotary cover 122 is rotatable relative to the water separating ring, and the limiting rib 126 is arranged on an outer peripheral surface of the water separating ring, or the limiting rib 126 is arranged on an inner peripheral surface of the water separating ring.

In this embodiment, the arrangement of the rotary cover 122 allows for direct manual control over the water flow capacity in the water inlet pipe 140 and/or the water outlet pipe 139. The limiting rib 126 and the adjustment portion are arranged to limit the rotatable angle of the rotary cover 122, ensuring that during the rotation of the adjusting knob, the rotary cover 122 does not carry the flow regulating valve 121 to be unscrewed out of the water pipe, thereby ensuring the use safety of the water heater. Additionally, the water separator 125 is provided to block the entry of water vapor between the rotary cover 122 and the shell 100 to some extent, preventing damage to the circuit element due to contact between external water vapor and the components in the water heater, thus prolonging the service life of the water heater. To ensure the water resistance between the rotary cover 122 and the shell 100, a water barrier ring is provided at the through hole on the shell 100. When the rotary cover 122 sleeves the water barrier ring, the rotary cover 122 does not contact the water barrier ring, ensuring the normal rotation of the rotary cover 122. And a water barrier maze groove is formed between the water barrier ring and the rotary cover 122 to block the external water vapor.

As shown in FIG. 2, the flow regulating valve 121 is disposed at the water inlet pipe 140 and can adjust the flow capacity of the inlet water.

Further, an end surface of the mounting shell extends to form a hollow pipe, in communication with the mounting shell, serving as a water outlet pipe 139 at a water exit.

In this embodiment, the end face of the mounting shell extends to form the connecting pipe 103 at the water outlet pipe 139, ensuring the connection strength between the connecting pipe 103 and the mounting shell. The other end of the connecting pipe 103 is threadedly connected to the heater 102.

It is worth mentioning that the outer wall of the connecting pipe 103 at the water outlet is provided with a connecting block 105. The connecting block 105 is provided with a threaded hole, and the set screw 138 passes through the threaded hole and is screwed to the shell 100, strengthening the connection between the connecting pipe 103 and the shell 100.

Specifically, the mounting shell includes a fixedly arranged first shell 114 and second shell 115. The first shell 114 and the connecting pipe 103 are arranged integrally. A first partition belt 116 is provided in the first shell 114. One end of the first partition belt 116 is disposed at the water inlet end of the first shell 114. The other end of the first partition belt 116 forms a vortex-like folded water flow channel after winding several turns in the first shell 114. A second partition belt is provided in the second shell 115. One end of the second partition belt is disposed at the water outlet end of the second shell 115. The other end of the second partition belt also forms a vortex-like folded water flow channel after winding several turns in the second shell 115. When the first shell 114 and the second shell 115 are fixed together, a water barrier 117 is clamped and fixed between the first shell 114 and the second shell 115. The water barrier 117 is provided with a flow-through hole, and the folded water flow channels in the first shell 114 and the second shell 115 communicate via the flow-through hole to form an extending water passage.

Further, the adjustment portion includes a first adjusting block 128 disposed in the rotary cover 122, and such limiting rib 126 is provided in a quantity of two. When the rotary cover 122 is connected to the control lever 124, the first adjusting block 128 is located between the two limiting ribs 126. A second adjusting block 129 is also disposed in the rotary cover 122. An adjustment angle is formed between a center of the rotary cover 122 and two side surfaces, back away from each other, of the first adjusting block 128 and the second adjusting block 129. When the first adjusting block 128 abuts against one of the limiting ribs 126, the flow regulating valve 121 is located at the position of a set maximum water flow capacity. When the second adjusting block 129 abuts against the other limiting rib 126, the flow regulating valve 121 is located at the position of a set minimum water flow capacity. As a range of the adjustment angle is changed, a flow capacity control range of the flow regulating valve 121 is changed.

In this embodiment, two limiting ribs 126 are provided. When the rotary cover 122 is connected to the control lever 124, the first adjusting block 128 is located between the two limiting ribs 126. With the arrangement of the two limiting ribs 126, the working stroke of the rotary cover 122 can be reduced; the angle between the two limiting ribs 126 can be adjusted according to different control requirements for the water flow capacity. Certainly, because the limiting rib 126 is fixed on the shell 100, the angle of the limiting rib 126 can be adjusted only by replacing the shell 100. The first adjusting block 128 can rotate between the two limiting ribs 126 to adjust the water flow capacity. To change the adjustment range of the water flow capacity, a second adjusting block 129 is provided in the rotary cover 122. An adjustment angle is formed between the center of the rotary cover 122 and the two side surfaces, back away from each other, of the first adjusting block 128 and the second adjusting block 129. As the adjustment angle range is changed, the capacity control range of the flow regulating valve 121 can be changed. Because both the first adjusting block 128 and the second adjusting block 129 are fixed in the rotary cover 122, different capacities are changed by replacing different rotary covers 122.

Further, a mounting ring is integrally disposed on a connecting pipe 103 at a water exit, the mounting ring communicates with the connecting pipe 103, a pressure relief valve 113 is disposed in the mounting ring, and an end of the pressure relief valve 113 extends out of the shell 100.

Further, a toothed key is annularly disposed on an outer peripheral surface of the control lever 124, a connecting ring 143 is disposed in the rotary cover 122, and a connection slot 131 is provided in the connecting ring 143. An inner wall of the connection slot 131 is annularly provided with a toothed slot, and the control lever 124 is fixed to the connecting ring 143 through insertion, such that the rotary cover 122 is separable from the control lever 124, making it convenient to replace the rotary cover 122 to adjust a different flow capacity range.

It is worth mentioning that the rotary cover 122 is provided with an indicator mark 132, which facilitates the positioning of the rotary cover 122 during assembly and also provides a marking function during water flow capacity adjustment.

Further, the shell 100 includes a mounting shell and an upper cover plate 123. The mounting shell is fixed to the upper cover plate 123 to form a mounting space for mounting the heater 102. A sealing ring sleeves the flow regulating valve 121, and when the mounting shell is fixed to the upper cover plate 123, the upper cover plate 123 and the flow regulating valve 121 clamp and fix the sealing ring. One end of the upper cover plate 123 is integrally provided with a connecting hook 136. The mounting shell is integrally provided with a landing edge 135, and the connecting hook 136 and the landing edge 135 hook each other. The other end of the upper cover plate 123 is detachably fixed and connected to the mounting shell. The control lever 124 extends out of the shell 100, an avoidance hole 127 is provided at the through hole, a sealing cover 109 is detachably disposed on the shell 100, and when the sealing cover 109 is fixed to the shell 100, the sealing cover 109 covers the insertion hole 120.

In this embodiment, to further ensure the air tightness of the shell 100, a sealing ring 142 is provided on the flow regulating valve 121 to seal the gap between the flow regulating valve 121 and the through hole. To facilitate the assembly of the shell 100, one end of the upper cover plate 123 is hooked with the fixed shell 134, so that the upper cover plate 123 can rotate around the hooked connection point. The entire fixed shell 134 can be fixed to the upper cover plate 123 by only fixing the other end of the upper cover plate 123 to the fixed shell 134. The detachable connection between the sealing cover 109 and the shell 100 can be achieved using screws, or a fastener may be provided on the sealing cover 109 or the shell 100 for snap connection.

It is worth mentioning that the detachable connection between the fixed shell 134 and the upper cover plate 123 can be achieved using set screw water separators 125. The set screw water separators 125 pass through the upper cover plate 123 and are screwed to the fixed shell 134, fixing the upper cover plate 123 and the fixed shell 134 together.

Further, a partial side surface of the shell 100 is recessed inward to form an L-shaped groove 130, the rotary cover 122 is located in the L-shaped groove 130, the rotary cover 122 is entirely or partially hidden in the L-shaped groove 130, and the rotary cover 122 is also integrally provided with an adjusting handle 141.

In this embodiment, a partial side surface of the shell 100 is recessed inward to form an L-shaped groove 130. The rotary cover 122 is hidden in the L-shaped groove 130, making the overall appearance more aesthetic. The design of the L-shaped groove 130 also provides enclosed protection for the rotary cover 122, preventing external objects from colliding with the rotary cover 122.

Further, the water heater further includes a filter 137. The filter 137 is detachably connected to the water inlet pipe 140 and/or the water outlet pipe 139, and the filter 137 is located outside the shell 100.

In this embodiment, to ensure the quality of the water flowing out of the water heater, a filter 137 is connected to the water inlet pipe 140 and/or the water outlet pipe 139 to filter the water flowing through the heater 102. The filter 137 is disposed outside the shell 100 and is easy to detach and replace.

Further, the water outlet pipe 139 is integrally provided with a mounting ring 119, the mounting ring 119 communicates with the water outlet pipe 139, a pressure relief valve 113 is provided in the mounting ring 119, and an end of the pressure relief valve 113 extends out of the shell 100.

In this embodiment, to prevent a safety hazard caused by excessive water pressure in the connecting pipe 103 at the water outlet, a pressure relief valve 113 is provided in the connecting pipe 103. When the water pressure exceeds the rated pressure, the pressure relief valve relieves the water pressure at the water outlet.
