Description

Technical Field

[0001] This utility model relates to the field of dental instrument and equipment technology, and in particular to a stainless steel water heater. Background Technology

[0002] In dental treatment, water heated to a specific temperature is needed for patients to rinse their mouths. Therefore, a heating device is required to heat the water to the appropriate temperature. In related technologies, the heating device includes a water heater installed inside the washbasin of the dental operating chair and a temperature sensor. A switch is located on the outside of the washbasin; when the switch is turned on, the water heater is powered on and heats the water inside. When the water is heated to a specific temperature, the switch automatically turns off. However, existing heating devices have poor temperature sensing performance and poor temperature stability of the heated water, which can easily lead to the water being too cold or too hot for the patient to rinse their mouth, causing pain and increasing patient discomfort. Utility Model Content

[0003] In order to overcome the technical defects mentioned in the background art, the purpose of this utility model is to provide a stainless steel water heater.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stainless steel water heater includes a cylinder, a heating element, and two thermostats. The cylinder contains a first chamber for heating water and a second chamber for mounting the thermostats. The cylinder has an inlet channel and an outlet channel, one end of each channel located within the first chamber. Both ends of the heating element pass through the sidewall between the first and second chambers and are electrically connected to the corresponding thermostats, with the heating element section located within the first chamber. Each thermostat has a power cord, the end of which is furthest from the thermostat and located on the outside of the cylinder.

[0006] By adopting the above technical solution, a set of thermostats is set at both ends of the heating tube. The thermostats are set close to the first cavity. The two sets of thermostats monitor the water heating in the first cavity, which has higher sensitivity and detection accuracy, and more precise water temperature control.

[0007] Furthermore, the two sets of thermostats and the two ends of the heating tubes form a square structure. The thermostats and the corresponding ends of the heating tubes are connected by wires, resulting in a compact structure that saves space and reduces the volume of the cylinder.

[0008] Furthermore, both the water inlet channel and the water outlet channel are located at the end of the cylinder where the first cavity is located. One end of the water outlet channel is connected to the water outlet connector, and the other end of the water outlet channel is located at the end of the first cavity near the second cavity, ensuring that hot water flows out of the water outlet channel, reducing the impact of water inlet and providing a better user experience.

[0009] Furthermore, the water inlet channel is located at one end of the cylinder where the first cavity is located, and the water outlet channel is located at the other end of the cylinder. One end of the water outlet channel is connected to a water outlet connector outside the cylinder, and the other end of the water outlet channel passes through the second cavity and is located inside the first cavity, resulting in higher temperature stability and avoiding the influence of the temperature of the water to be heated entering from the water inlet channel. The other end of the water outlet channel is located on one side of the heating tube to ensure the temperature of the outlet water.

[0010] Furthermore, the water outlet channel is arranged along the central axis of the cylinder, resulting in a more stable water temperature in the middle. Moreover, the structure is compact and the placement is well-designed, which helps to reduce the volume of the cylinder.

[0011] Furthermore, the cylindrical body includes a shell, a mounting plate, and a cover plate. One end of the shell is open, and the mounting plate is welded to the inside of the cylindrical body to divide the interior of the shell into a first cavity and a second cavity, which are integrally formed for better sealing performance. Mounting posts are spaced apart on the mounting plate, and these posts are located within the second cavity. The cover plate seals the open end of the shell, and the cover plate is screwed to the mounting posts, making installation and disassembly simple and convenient.

[0012] Furthermore, the mounting plate is provided with multiple mounting holes spaced apart, and a fixing sleeve is welded into each mounting hole. One end of the fixing sleeve has a fixing hole, and the other end protrudes from the mounting plate. This allows for the use of a thinner mounting plate, saving costs and increasing the water storage space of the first cavity. The fixing sleeve also improves installation stability. Each mounting post is inserted into one fixing sleeve, and each set of thermostats has two corresponding fixing sleeves threadedly connected to them, making installation and disassembly more convenient.

[0013] Furthermore, the cylinder is designed as a cylindrical structure, which reduces the space it occupies and enhances its compatibility. The space of the first cavity is larger than that of the second cavity, increasing the water storage capacity.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] In this invention, a set of thermostats is provided at both ends of the heating tube. The thermostats are located close to the first cavity. The two sets of thermostats monitor the water heating in the first cavity, resulting in higher sensitivity and detection accuracy, and more precise water temperature control.

[0027] The following is in conjunction with the appendix Figure 1-6 The embodiments of this utility model will be described in further detail below.

[0028] A stainless steel water heater 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, it includes a cylinder 2, a heating element 3, and two sets of thermostats 4. The cylinder 2 contains a first chamber 21 for heating water and a second chamber 22 for mounting the thermostats 4. The cylinder 2 has an inlet channel 5 and an outlet channel 6, one end of which is located within the first chamber 21. Both ends of the heating element 3 pass through the sidewall between the first chamber 21 and the second chamber 22 and are electrically connected to the corresponding thermostats 4. The section of the heating element 3 is located within the first chamber 21. Each thermostat 4 has a power cord 7, with the end of the power cord 7 furthest from the thermostat 4 located on the outside of the cylinder 2. Each end of the heating element 3 is equipped with a thermostat 4, positioned adjacent to the first chamber 21. These two sets of thermostats 4 monitor the water heating status within the first chamber 21, providing higher sensitivity and detection accuracy, and more precise water temperature control.

[0029] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 4 The two sets of thermostats 4 and heating tubes 3 form a square structure at both ends. The thermostats 4 and the corresponding heating tubes 3 are connected by wires. The structure is compact, saves space, and reduces the volume of the cylinder 2.

[0030] In one embodiment, please refer to Figure 2 , Figure 3 Both the inlet channel 5 and the outlet channel 6 are located at the end of the cylinder 2 where the first cavity 21 is located. One end of the outlet channel 6 is connected to the outlet connector, and the other end of the outlet channel 6 is located at the end of the first cavity 21 near the second cavity 22, ensuring that hot water flows out of the outlet channel 6, reducing the impact of incoming water, and providing a better user experience. One end of the inlet channel 5 is connected to the inlet connector, and the other end of the inlet channel 5 is located inside the first cavity 21, reducing the impact of water flow on the temperature of the heated water and improving the accuracy of temperature control.

[0031] In another embodiment, please refer to Figure 5 , Figure 6 The water inlet channel 5 is located at one end of the cylinder 2 where the first cavity 21 is located, and the water outlet channel 6 is located at the other end of the cylinder 2. One end of the water outlet channel 6 is connected to the water outlet connector outside the cylinder 2, and the other end of the water outlet channel 6 passes through the second cavity 22 and is located inside the first cavity 21, resulting in higher temperature stability and avoiding the influence of the temperature of the water to be heated entering from the water inlet channel 5. The other end of the water outlet channel 6 is located on one side of the heating pipe 3. The water inlet channel 5 and the water outlet channel 6 are respectively located at both ends with no interaction area, avoiding the influence of the incoming water on the temperature of the heated water being delivered, and ensuring the temperature of the outlet water.

[0032] Preferably, the water outlet channel 6 is arranged along the central axis of the cylinder 2, which makes the water temperature in the middle more stable. Moreover, the structure is compact and the placement is convenient, which helps to reduce the volume of the cylinder 2. The water inlet channel 5 is also located in the center of the first cavity 21, which facilitates the uniform diffusion of water flow to make the water temperature inside more balanced and prevent local overheating or overcooling.

[0033] In some embodiments, please refer to Figure 4 The cylindrical body 2 includes a shell 23, a mounting plate 24, and a cover plate 25. One end of the shell 23 is open. The mounting plate 24 is welded inside the cylindrical body 2, dividing the interior of the shell 23 into a first cavity 21 and a second cavity 22. This integral molding process provides better sealing performance. Mounting posts 26 are spaced apart on the mounting plate 24 and are located within the second cavity 22. The cover plate 25 seals the open end of the shell 23 and is screwed to the mounting posts 26, making installation and disassembly simple and convenient.

[0034] Preferably, the mounting plate 24 has multiple mounting holes spaced apart, and a fixing sleeve 27 is welded into each mounting hole. One end of the fixing sleeve 27 in the second cavity 22 has a fixing hole, and the other end of the fixing sleeve 27 protrudes from the mounting plate 24. This allows for the use of a thinner mounting plate 24, saving costs, and also increases the water storage space of the first cavity 21. The fixing sleeve 27 also improves installation stability. Each mounting post 26 is inserted into one fixing sleeve 27, and each thermostat 4 has two corresponding fixing sleeves 27 with threaded connections, making installation and disassembly more convenient.

[0035] Specifically, the cylinder 2 is designed as a cylindrical structure, which reduces the space occupied by the cylinder 2 and enhances its compatibility. The space of the first cavity 21 is larger than that of the second cavity 22, thereby increasing the water storage capacity.

[0036] In use, external water is supplied to the first chamber 21 through the inlet channel 5. The heating element 3 heats the water in the first chamber 21. Two sets of thermostats 4 can monitor and control the water temperature in the first chamber 21 in real time. The water temperature of this stainless steel heater can be controlled at 55°C. When the thermostat 4 detects that the water temperature has reached 55°C, it can automatically cut off the power, thus stopping the heating element 3 from heating. This automated control provides higher precision and faster reversal efficiency. The heated water can be drawn out from the outlet channel 6 for user use. The operation is simple and the temperature control stability is higher.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
