[0001] The invention relates to the technical field of household appliances, and in particular to a waterproof switch for a water heater and a water heater. Background Art
[0002] For consumers, household gas water heaters are becoming more and more widely used in the water heater field due to their efficient and comfortable heating method. However, during use, there is also the problem of inconvenience for users to adjust the temperature.
[0003] In order to ensure the aesthetics and consistency of the water heater surface and facilitate user operation, some manufacturers set the control switch of the water heater to touch type. However, when installing household gas water heaters, due to safety requirements, household gas water heaters are generally installed in kitchens or balconies, where there is a lot of oil smoke. The oil smoke is easy to adhere to the surface of the touch button, resulting in the insensitivity of the general touch button.
[0004] In order to improve the above-mentioned problems, the gas water heater in the prior art changes the touch switch to a knob switch. However, when the knob switch is installed, there is a gap between the knob switch and the outer casing of the water heater. Also, because it is installed in a balcony or kitchen, the air humidity is high or rainy weather can easily cause water vapor to enter the circuit board connected to the knob switch, posing a safety hazard. Summary of the invention
[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the gap at the knob switch of the gas water heater in the prior art is easy to enter water vapor, thereby providing a water heater waterproof switch and a water heater.
[0006] In order to solve the above problems, the present invention provides a device comprising: a knob; a panel, on which a via is formed, and the knob portion passes through the via and is connected to the component to be used; and a seal, which is arranged at the gap formed by the knob and the via to seal the gap.
[0007] Furthermore, a flange is formed on the circumference of the through hole toward the knob, and the sealing member is arranged on the flange.
[0008] Furthermore, the flange is parallel to the axis of the through hole.
[0009] Further, the sealing member is constructed as an annular structure, having a connecting portion acting on the flange and a supporting portion abutting against the knob.
[0010] Furthermore, an annular groove is formed on the connecting portion, and the annular groove is tension-clamped on the flange.
[0011] Further, the axial cross section of the support portion is configured to be "V"-shaped and abuts against the knob.
[0012] Furthermore, a water hole is formed on an outer side of the support portion away from the knob.
[0013] Furthermore, the knob has a rotating portion protruding from the panel and a socket coaxially formed on the rotating portion, and the socket is plugged into the display box assembly.
[0014] Furthermore, the “V”-shaped head abuts against the end surface of the rotating portion facing the panel.
[0015] The water heater waterproof switch of the present invention further comprises a housing, and the panel is arranged on the housing.
[0016] A water heater comprises: any one of the above-mentioned waterproof switches for water heaters.
[0017] The technical solution of the present invention has the following advantages:
[0018] 1. The water heater waterproof switch of the present invention comprises: a knob; a panel, a through hole formed on the panel, the knob part passes through the through hole and is connected to the component to be used; and a sealing member, which is arranged at the gap formed by the knob and the through hole to seal the gap.
[0019] When the knob is installed on the panel, in order to ensure smooth rotation, there are gaps between the knob and the through hole, and between the knob and the horizontal plane of the panel. Water vapor can easily enter the water heater through the gaps described above.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0041] Example 1
[0042] Figures 1 to 3 As shown, a waterproof switch for a water heater provided in an embodiment includes a knob 1; a panel 2, on which a through hole 21 is formed, and the knob 1 partially passes through the through hole 21 and is connected to the component to be used; and a sealing member 5, which is arranged in the gap formed by the knob 1 and the through hole 21 to seal the gap.
[0043] In the prior art, when the knob 1 is installed on the panel 2, in order to ensure smooth rotation, there are gaps between the knob 1 and the through hole 21, and between the knob 1 and the horizontal plane of the panel 2. Water vapor can easily enter the water heater through the gaps described above. In this embodiment, a seal 5 is provided at the above-mentioned gap to block the passage of external water vapor into the water heater through the gap, so as to solve the problem of water vapor entering the existing knob switch.
[0044] The ready-to-actuate component in this embodiment is a display box component 4, and the knob 1 is connected to the display box component 4 to realize the control of the water heater.
[0045] It should also be noted that, in order to save costs and speed up batch processing, the knob 1 and the panel 2 in this embodiment are both injection molded, and the material is ABS.
[0046] The through hole 21 in this embodiment is circular, matching the shape and size of the knob 1 to facilitate the installation of the knob 1. Of course, in some other implementations, the shape of the through hole 21 may also be a common design pattern such as a square or a triangle.
[0047] In addition, the material of the sealing member 5 in this embodiment is rubber. Rubber is waterproof and soft, and is easier to fit on the surface of an object, thereby preventing the generation of a contact gap and ensuring good sealing performance.
[0048] It can be imagined that the gap between the edge of the through hole 21 and the knob 1 is a part of the through hole 21, and water vapor can easily pass through the gap. Therefore, in this embodiment, a flange 211 is formed on the circumference of the through hole 21 toward the knob 1, and the sealing member 5 is arranged on the flange 211. The flange 211 is designed to protrude from the edge of the through hole 21, and a part of it can prevent water vapor from directly entering the through hole 21. For another part, water vapor needs to enter the through hole 21 along the peripheral wall of the flange 211, which increases the travel distance of water vapor entering the through hole 21, making it more difficult for water to enter.
[0049] For the convenience of processing and subsequent installation of the sealing member 5 , the flange 211 is parallel to the axis of the through hole 21 .
[0050] like Figure 3 As shown, the seal 5 is constructed as an annular structure, having a connecting portion 51 acting on the flange 211 and a supporting portion 52 abutting against the knob 1. An annular groove 511 is formed on the connecting portion 51, and the annular groove 511 is clamped on the flange 211. The structure of the annular groove 511 determines that its two groove edges act on the flange 211. When water vapor enters the water heater through this, the structure of the annular groove 511 extends the length of the water vapor path, which can improve the waterproof effect. On the other hand, the installation portion of the annular groove 511 makes the installation of the seal 5 easier.
[0051] Furthermore, the axial cross section of the support portion 52 is constructed in a "V" shape and abuts against the knob 1. On the one hand, the contact surface of the "V" shape and the knob 1 forms a triangular structure, which can have a high-strength support effect. On the other hand, when water vapor passes through one side of the above-mentioned support portion, the middle groove of the "V" shape can play a certain role in storing water, and the stored water can be discharged through the annular structure of the seal 5 itself, which can further enhance the waterproof effect.
[0052] like Figure 1 As shown, the "V"-shaped head abuts against the end surface of the rotating part 11 facing the panel 2. The "V"-shaped head abuts against the end surface of the rotating part at two places, thereby forming a double-layer waterproof seal, which can enhance the waterproof effect.
[0053] At the same time, a water hole is formed on the outer side of the support portion 52 away from the knob 1. The blocked part of the water vapor will gather at the bottom of the "V"-shaped support portion 52, and the water hole can guide this part of the water to the outside in time to ensure a good waterproof effect.
[0054] In order to ensure that the water vapor is smoothly discharged, the bottom of the "V" groove is also processed with a guide groove (not shown in the figure) spirally arranged along the bottom of the groove. The tail end of the guide groove is connected to the water hole, and the height gradually decreases in the direction close to the water hole.
[0055] The knob 1 in this embodiment has a rotating portion 11 protruding from the panel 1 and a socket 12 coaxially formed on the rotating portion 11. The socket 12 is plugged into the display box assembly 4. Figure 1 As shown, a plug is formed on the display box assembly 4 to cooperate with the socket 12, and the socket 12 and the plug cooperate to fix the knob 1. Anti-slip grooves are also formed on the circumference of the rotating part 11 to increase the friction during rotation and facilitate user use.
[0056] This embodiment further comprises a housing 3, and the panel 2 is arranged on the housing 3. The panel 2 in this embodiment is mounted on the housing 3 in an adhesive manner.
[0057] Example 2
[0058] Figure 4 and Figure 5 As shown, a water heater provided in this embodiment includes the above-mentioned water heater waterproof switch and has all its technical advantages. On the one hand, it can prevent water vapor from entering the water heater and increase the service life of the water heater. At the same time, it can also prevent the safety hazards caused by water vapor entering the water heater and ensure the safety of users.
[0059] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
