Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, specifically to an instant heating component and a drinking water equipment. Background Technology

[0002] With the improvement of living standards, water dispensers with instant hot and cold water functions are becoming increasingly popular among users. In related technologies, heating the instant heating element often involves controlling the instant heating element to run for a certain period of time while transferring the heat generated by the heating element to the drinking water to complete the heating of the drinking water. However, this method often leads to the instant heating element burning dry, thereby reducing the service life of the water dispenser. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this utility model is to provide an instant heating component for a drinking water device that can respond promptly based on the status of the instant heating component in the drinking water device, preventing dry burning and thus improving the service life of the drinking water device.

[0004] The second objective of this utility model is to provide a drinking water device.

[0005] To achieve the above objectives, this utility model proposes an instant heating component for a drinking water device. The instant heating component includes: a housing with an inlet and an outlet; a heating tube positioned near the inlet relative to the outlet; and a temperature control device connected in series on the power supply line of the heating tube, which disconnects when the ambient temperature of the temperature control device exceeds the power-off protection temperature, thereby stopping the heating tube from operating.

[0006] The instant heating component of this utility model includes a shell, a heating tube, and a temperature control device. The temperature control device is connected in series with the heating tube. After drinking water enters the instant heating tube from the inlet, it is heated by the heating tube and then sent out from the outlet. The temperature control device can determine whether the heating tube is dry-burning according to the environment in which it is set. If so, it will cut off the power to the heating tube to stop the heating tube from running, thereby preventing the instant heating component from dry-burning and thus improving the service life of the drinking water equipment.

[0007] In some examples of this utility model, the temperature control device includes a temperature controller and a temperature limiter, which are connected in series.

[0008] In some examples of this utility model, the thermostat is positioned close to the outlet relative to the inlet, and the temperature limiter is positioned between the thermostat and the heating element.

[0009] In some examples of this utility model, the instant heating component is vertically installed on the drinking water device, wherein the water inlet is located at the lower end of the instant heating component and the water outlet is located at the upper end of the instant heating component.

[0010] In some examples of this utility model, the instant heating component further includes a spiral guide column, which is installed inside the housing and is used to spirally guide drinking water from the inlet to the outlet.

[0011] In some examples of this utility model, the outer shell has a tubular structure, and the distance difference between the inner diameter of the outer shell and the outer diameter of the spiral guide column is within a preset distance range.

[0012] In some examples of this utility model, the inlet and the outlet are respectively located at both ends of the spiral guide column.

[0013] In some examples of this utility model, both the inlet and the outlet are provided with sealing rings.

[0014] In some examples of this utility model, the instant heating component further includes: an actual inlet water temperature detector, which is disposed at the water inlet and is used to detect the actual inlet water temperature of the instant heating component; an actual outlet water temperature detector, which is disposed at the water outlet and is used to detect the actual outlet water temperature of the instant heating component; and a control device, which is connected to the actual inlet water temperature detector, the actual outlet water temperature detector and the heating tube respectively, and the control device is used to control the heating tube according to multiple temperatures among the actual inlet water temperature, the actual outlet water temperature and the target outlet water temperature.

[0015] To achieve the above objectives, this utility model proposes a drinking water device, which includes the instant heating component of the drinking water device in the above example.

[0016] The water dispenser in this example, through the instant heating component of the water dispenser in the above example, can respond in a timely manner according to the status of the instant heating component in the water dispenser, preventing the instant heating component from burning dry, thereby improving the service life of the water dispenser.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] The instant heating component and drinking water device of the present invention are described below with reference to the accompanying drawings.

[0026] See Figure 1 and Figure 2 The instant heating component 10 of the drinking water equipment of this utility model includes a housing 19, a heating element 15, and a temperature control device. The housing 19 is provided with a water inlet 17 and a water outlet 11; the heating element 15 is positioned close to the water inlet 17 relative to the water outlet 11; the temperature control device is connected in series with the power supply line of the heating element 15 so as to disconnect when the temperature of the environment where the temperature control device is located is higher than the power-off protection temperature, thereby stopping the operation of the heating element 15.

[0027] Specifically, the drinking water device in this embodiment can be a household water dispenser or a large water dispenser used in schools, factories, etc. The drinking water device includes an instant heating component 10 for instant heating of drinking water. The instant heating component 10 has a housing 19, a heating element 15, and a temperature control device. The housing 19 has an inlet 17 and an outlet 11. Drinking water enters the instant heating component 10 through the inlet 17 and exits through the outlet 11. The heating element 15 heats the drinking water entering the instant heating component 10. The temperature control device is designed to cut off the power to the heating element 15 when the ambient temperature detected by the temperature control device in the heating component exceeds the power-off protection temperature, thereby preventing the heating element 15 from dry burning and extending its service life. The temperature control device is installed on the power supply line of the heating tube 15 and detects the temperature of the environment where the temperature control device is located. When the temperature of the environment where the temperature control device is located is detected to be higher than the power-off protection temperature, the heating tube 15 is controlled to stop running, thereby protecting the heating tube 15 and preventing other components in the instant heating component 10 from being damaged due to overheating, thus improving the service life of the water drinking equipment.

[0028] In one embodiment of this utility model, the temperature control device includes a thermostat 13 and a temperature limiter 14, which are connected in series. The thermostat 13 is positioned near the outlet 11 relative to the inlet 17, and the temperature limiter 14 is positioned between the thermostat 13 and the heating element 15.

[0029] Specifically, see Figure 1 and Figure 2The thermostat 13 and the temperature limiter 14 are used to detect the temperature of the hot water heated by the heating element 15 and control the heating element 15 according to the hot water temperature to prevent dry burning. More specifically, the thermostat 13 detects the ambient temperature. When the temperature is greater than or equal to the power-off protection temperature, it disconnects to protect the heating element 15 from power loss. When the temperature is less than the power-off protection temperature, it resets to allow the heating element 15 to be powered on. Similarly, the temperature limiter 14 detects the ambient temperature. When the temperature is greater than or equal to the power-off protection temperature, it disconnects to protect the heating element 15 from power loss. When the temperature is less than the power-off protection temperature, it does not reset and requires manual reset. The thermostat 13 is positioned closer to the water outlet 11 than the temperature limiter 14. Since the heating element 15 is located near the water inlet 17, the thermostat 13, in effect, is positioned further away from the heater than the temperature limiter 14. Furthermore, because the instant heating element 10 is vertically installed with the water inlet 17 at the bottom and the water outlet 11 at the top in the water dispenser, if the heating element 15 burns dry, the steam it produces will rise. The thermostat 13, being positioned higher, will detect a higher temperature, thus responding earlier to protect the water dispenser. The thermostat 13 also has an automatic reset function, further reducing manual labor. Of course, to further reduce manual labor, the response temperature of the thermostat 13 can be set lower than that of the temperature limiter 14, depending on the specific application.

[0030] In this embodiment, see Figure 2 and Figure 3 As shown, the instant heating assembly 10 also includes a spiral guide column 18, which is installed inside the housing 19 and is used to spirally guide drinking water from the inlet 17 to the outlet 11. The inlet 17 and the outlet 11 are respectively located at both ends of the spiral guide column 18.

[0031] Specifically, after drinking water enters through inlet 17, it spirals upwards evenly along the spiral guide column 18. This ensures uniform heating and a smooth water flow during the heating process, reducing air bubbles generated during the heating process and minimizing heating noise and water flow fluctuations. In this embodiment, the outer shell 19 has a tubular structure. Considering the installation of the spiral guide column 18 and its flow guiding function, the distance difference between the inner diameter of the outer shell 19 and the outer diameter of the spiral guide column 18 is within a preset range. Specifically, a gap of approximately 0.1-0.5 mm needs to be maintained between the outer diameter of the spiral guide column 18 and the inner diameter of the instant heating component 10. Furthermore, to ensure water quality hygiene, the spiral guide column 18 can also be made of 304 stainless steel.

[0032] In this embodiment, to prevent water leakage, sealing rings are provided at both the inlet 17 and the outlet 11 to prevent water waste. If the inlet 17 leaks, air bubbles will be generated in the spiral guide column 18, increasing the operating noise of the instant water heating component 10. If the outlet 11 leaks, it is very likely to cause scalding to the user, greatly reducing the user experience of the water drinking equipment. Therefore, sealing rings are provided at both the inlet 17 and the outlet 11 to improve the safety and energy efficiency of the water drinking equipment.

[0033] In some embodiments of this utility model, the heating component 10 further includes an actual inlet water temperature detector 16, an actual outlet water temperature detector 12, and a control device (not shown in the figure).

[0034] The actual inlet water temperature detector 16 is installed at the inlet 17 to detect the actual inlet water temperature of the instant heating component 10; the actual outlet water temperature detector 12 is installed at the outlet 11 to detect the actual outlet water temperature of the instant heating component 10; the control device is connected to the actual inlet water temperature detector 16, the actual outlet water temperature detector 12 and the heating tube 15 respectively, and the control device is used to control the heating tube 15 according to multiple temperatures among the actual inlet water temperature, the actual outlet water temperature and the target outlet water temperature.

[0035] Specifically, in this embodiment, the target water temperature can be pre-set or selected by the user when taking water. A selection device, such as a touchscreen or button, can be installed on the water dispenser for the user to choose from. Once the user selects the target temperature, the target water temperature is determined. When the water dispenser dispenses water, the actual inlet water temperature detector 16 at the inlet 17 and the actual outlet water temperature detector 12 at the outlet 11 detect the passing drinking water, thereby detecting the actual inlet water temperature and the actual outlet water temperature of the instant heating element 10. After determining the target water temperature, the actual inlet water temperature, and the actual outlet water temperature, the control device can determine whether the instant heating element 10 is in a dry-burning state based on multiple of these three temperatures using different judgment methods. If so, it immediately controls the heating element 15 to stop operating, preventing the heating element 15 from dry-burning and reducing the service life of the instant heating element 10, or causing damage to other components of the water dispenser, thereby improving the service life of the water dispenser. Of course, if it is determined that the heating element 15 is not in a dry-burning state, the actual outlet water temperature and the actual inlet water temperature can be obtained again, and the state of the heating element 15 can be re-determined based on the target outlet water temperature and the re-obtained actual inlet water temperature and actual outlet water temperature.

[0036] In one embodiment, preventing the heating element 15 from dry-burning specifically aims to prevent the instantaneous heating element from generating excessive heat. Therefore, it is necessary to detect the water temperature after heating. The inlet water temperature is generally room temperature, so it does not need to be detected. However, the target outlet water temperature affects the outlet water temperature of the instantaneous heating element 10. Therefore, the control device in this embodiment can determine the dry-burning protection temperature based on the target outlet water temperature. Then, the actual outlet water temperature is compared with the dry-burning protection temperature. If the actual outlet water temperature is consistently higher than the dry-burning protection temperature within a first preset time period, it can be determined that the heating element 15 is currently in a dry-burning state, and subsequent power-off protection is executed. Optionally, the first preset time period in this embodiment is 6 seconds, 7 seconds, or 8 seconds. It should be noted that the specific value of the first preset time period in this embodiment can be determined according to the actual application scenario and is not specifically limited here.

[0037] In this embodiment, determining the dry-burn protection temperature based on the target outlet water temperature can be achieved by first calculating the sum of the target outlet water temperature and a first preset temperature, where the first preset temperature can be 20 degrees Celsius, 30 degrees Celsius, 35 degrees Celsius, etc. In this embodiment, the first preset temperature is relatively large. Therefore, to avoid the first sum exceeding the boiling point of drinking water, the first sum is compared with a second preset temperature, and the dry-burn protection temperature is determined based on the comparison result. The second preset temperature can be the boiling point of drinking water. If the first sum is greater than or equal to the second preset temperature, continuing to use the first sum as the dry-burn protection temperature may affect the dry-burn protection response of the heating element 15. Therefore, the dry-burn protection temperature can be determined based on the second preset temperature. If the first sum is less than the second preset temperature, the dry-burn protection can be determined based on the second preset temperature. Specifically, the second sum obtained by adding the first sum to a third preset temperature can be determined as the dry-burn protection temperature, where the third preset temperature can be 2 degrees Celsius, 3 degrees Celsius, or 4 degrees Celsius, etc. It should be noted that in this embodiment, the first sum can also be used directly as dry burning protection, that is, the third preset temperature can be 0 degrees Celsius.

[0038] In another embodiment, the control device determines whether the heating element 15 is in a dry-burning state by first determining a dry-burning protection temperature based on the target outlet water temperature. Specifically, the target outlet water temperature can be increased by a small temperature threshold, such as 3 degrees Celsius or 4 degrees Celsius. After determining the dry-burning protection temperature, the control device can compare the actual outlet water temperature with the dry-burning protection temperature and judge the actual inlet water temperature. Then, based on the comparison and judgment results, it determines whether the heating element 15 is in a dry-burning state. Since the heating element 15 in this embodiment is located close to the actual inlet water temperature detector 16, if the heating element 15 is dry-burning, a large amount of water vapor will be generated when drinking water passes through the heating element 15. The water vapor will affect the temperature detection result of the nearby actual inlet water temperature detector 16. Therefore, this embodiment also needs to determine whether the actual inlet water temperature has risen to a fourth preset temperature within a third preset time period, and combine the judgment result to determine whether the heating element 15 is dry-burning. Optionally, the second preset duration and the third preset duration in this embodiment can be the same or different, for example, they can be 6 seconds, 7 seconds, 8 seconds, etc., while the fourth preset temperature can be 14 degrees Celsius, 15 degrees Celsius, 16 degrees Celsius, etc.

[0039] To better remind users of the current status of the water dispenser, when the heating element 15 is dry-burned and the system stops operating, the control device can also report the fault code of the water dispenser, or display the fault code on the display screen of the water dispenser. Of course, it can also be accompanied by sound prompts, such as beeping sounds, to ensure that the water dispenser can be maintained in a timely manner and further improve the service life of the water dispenser.

[0040] In summary, the instant heating component of the water dispenser in this invention can respond promptly according to the status of the instant heating component in the water dispenser, preventing the instant heating component from burning dry, thereby improving the service life of the water dispenser.
