Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection technology, and in particular to a water inlet channel and a cooking device containing the same. Background Technology
[0002] In cooking appliances containing evaporators, such as steam ovens and steam ovens, the water tank is a fundamental component responsible for storing the water necessary for the cooking process. As cooking continues, the water level in the tank gradually decreases. If water is not replenished in time, the appliance may experience dry burning due to continuous heating without water, which can even pose a safety hazard. Therefore, it is essential to install a detection device in the water inlet circuit of the cooking appliance to monitor the water level in the tank in real time and issue an alarm when water is low.
[0003] In existing technologies, cooking equipment alarms typically rely on abnormal temperature changes in the evaporator to determine if the water tank is low. On one hand, evaporator temperature changes are influenced by various factors, such as ambient temperature and the age of the equipment. When the ambient temperature is high or the equipment has been used for a long time and is aging, a natural rise in evaporator temperature may be misinterpreted as a low water level, leading to an incorrect low water alarm. On the other hand, because evaporator temperature changes relatively slowly, the entire process from low water level to abnormal temperature and then to the triggering of the low water alarm is quite lengthy. This means users may not receive timely low water alerts, affecting the continuity of cooking and the taste of food, and may even lead to slight dry burning.
[0004] In view of the above problems, there is an urgent need to design a water inlet circuit that can quickly and accurately determine the water shortage in the water tank and a cooking device containing it. Utility Model Content
[0005] In view of this, the present invention provides a water inlet channel and a cooking device containing the same, to solve the problem that existing cooking devices cannot quickly and accurately determine the lack of water in the water tank.
[0006] To solve the above-mentioned technical problems, one technical solution adopted by this utility model is to provide a water inlet circuit, which includes a water inlet pipe, a water storage box, a water inlet pump and a water level sensor. The water storage box and the water inlet pump are located in the water inlet pipe, and the water level sensor is located in the water storage box. One end of the water inlet pipe is used to connect to the water tank of the cooking equipment, and the other end is used to connect to the evaporator of the cooking equipment.
[0007] As an embodiment of this utility model, the water inlet pipeline includes a first pipe, a second pipe, and a third pipe. One end of the first pipe is connected to the water tank of the cooking equipment, and the other end is connected to the water storage box. One end of the second pipe is connected to the water storage box, and the other end is connected to the inlet end of the water inlet pump. One end of the third pipe is connected to the outlet end of the water inlet pump, and the other end is connected to the evaporator of the cooking equipment.
[0008] As an embodiment of this utility model, the water inlet pipeline includes a first pipe, a second pipe, and a third pipe. One end of the first pipe is connected to the water tank of the cooking device, and the other end is connected to the inlet end of the water pump. One end of the second pipe is connected to the outlet end of the water pump, and the other end is connected to the water storage box. One end of the third pipe is connected to the water storage box, and the other end is connected to the evaporator of the cooking device.
[0009] As an embodiment of this utility model, the water storage box is provided with an inlet and an outlet. The inlet is connected to the first pipe and is used to connect to the water tank of the cooking device. The outlet is connected to the second pipe and is connected to the inlet end of the water pump.
[0010] As an embodiment of this utility model, the water storage box is provided with an inlet and an outlet. The inlet is connected to the second pipe and is connected to the outlet of the water pump. The outlet is connected to the third pipe and is used to connect to the evaporator of the cooking device.
[0011] In one embodiment of this utility model, the height of the water inlet is higher than the height of the water outlet.
[0012] In one embodiment of this utility model, the water outlet is tangent to the bottom wall of the water storage box.
[0013] In one embodiment of this utility model, the capacity of the water storage box is smaller than the capacity of the water tank.
[0014] In one embodiment of this utility model, the water level sensor is attached to the side wall of the water storage box.
[0015] To solve the above-mentioned technical problems, this utility model also provides a cooking device, which includes a water inlet channel, and the water inlet channel is the aforementioned water inlet channel.
[0016] Compared with the prior art, the water inlet channel and cooking device containing it provided in this embodiment of the utility model have the following advantages:
[0017] 1. The water inlet circuit provided by this utility model, by setting up an inlet pipe, connects its two ends to the water tank and the evaporator respectively, and places the water storage box and the water pump in the inlet pipe, allows water flowing from the water tank to flow through the water storage box and then into the evaporator. A water level sensor is installed in the water storage box, which acts as an intermediary to indirectly reflect the water level in the water tank by detecting the water level in the storage box. This accurately detects the water shortage status in the water tank, improving the accuracy of detection. Furthermore, since the water level sensor can monitor the water level in the storage box in real time, when there is no water in the water tank and no water flows into the storage box, the water level sensor can detect the absence of water in the storage box in real time, thereby improving the detection speed. Therefore, the water inlet circuit provided by this utility model effectively solves the problem that existing cooking equipment cannot quickly and accurately determine the water shortage in the water tank.
[0018] 2. In the water inlet circuit provided by this utility model, the water inlet pump is located between the water storage box and the evaporator, or between the water tank and the water storage box. It can draw water from the water tank and send it into the water storage box, realizing active control of the water flow. It actively makes the water in the water tank flow into the water storage box more smoothly and efficiently, improves the stability and controllability of the water flow out of the water tank, and makes the water flowing from the water tank into the water storage box and then into the evaporator more smoothly and efficiently. This improves the accuracy and reliability of the water inlet circuit in detecting the water shortage in the water tank.
[0019] 3. In the water inlet circuit provided by this utility model, by setting the height of the water inlet to be higher than that of the water outlet, the water inlet is opened at a higher position in the water storage box, while the water outlet is opened at a lower position in the water storage box. This allows the water flowing out of the water tank to flow into the water storage box from a higher position and to discharge from a lower position, which conforms to the flow direction of water under the action of gravity, thereby improving the sensitivity of detection and effectively preventing the risk of dry burning.
[0020] 4. In the water inlet circuit provided by this utility model, by setting the water outlet position close to the bottom of the water storage box and tangent to the bottom wall of the water storage box, it can ensure that the water in the water storage box can be quickly and completely drained when there is a lack of water, so that an alarm can be issued in time even when the water volume is very small, improving the sensitivity of detection and further effectively preventing the risk of dry burning.
[0021] 5. In the water inlet circuit provided by this utility model, by setting the capacity of the water storage box to be smaller than that of the water tank, it can ensure that when the water level in the water tank decreases to a certain level, the water flowing into the water storage box can be emptied in time to avoid water accumulation or residue. This allows the water level sensor to detect the water tank being low on water in a timely manner and trigger an alarm signal. Therefore, this design makes the water inlet circuit more sensitive to changes in the water level in the water tank and effectively prevents dry burning.
[0022] 6. In the water inlet circuit provided by this utility model, by attaching the water level sensor to the side wall of the water storage box, the water level sensor can accurately sense the water level change in the water storage box, reducing errors caused by air gaps or water evaporation, ensuring that the detected water level signal data is accurate, improving the accuracy of detection, and also facilitating the installation and maintenance of the water level sensor.

[0037] Example 1
[0038] Please see Figure 1As shown, the first embodiment of this utility model discloses a water inlet circuit 1, which can be used, but is not limited to, in cooking equipment. The water inlet circuit 1 includes a water inlet pipe 14, a water storage box 11, a water inlet pump 13, and a water level sensor 12. The water storage box 11 and the water inlet pump 13 are located in the water inlet pipe 14, and the water level sensor 12 is located in the water storage box 11. One end of the water inlet pipe 14 is used to connect to the water tank 2 of the cooking equipment, and the other end is used to connect to the evaporator 3 of the cooking equipment.
[0039] Specifically, the water in the inlet pipe 14 flows out of the water tank 2, through the water storage box 11 and the water purification pump, and finally flows into the evaporator 3. The water level sensor 12 is used to detect the water level in the water storage box 11. The water storage box 11 is used as an intermediary to indirectly detect whether the water tank 2 is short of water. The water level sensor 12 is not installed on the water tank 2 to directly detect the water level in the water tank 2, which makes it convenient to take the water tank 2 directly out of the cooking equipment.
[0040] It is understandable that by setting up a water inlet pipe 14, connecting its two ends to the water tank 2 and the evaporator 3 respectively, and placing the water storage box 11 and the water pump 13 in the water inlet pipe 14, water flowing from the water tank 2 can flow through the water storage box 11 and then into the evaporator 3. A water level sensor 12 is installed in the water storage box 11, which acts as an intermediary to indirectly reflect the water level in the water tank 2 by detecting the water level in the water storage box 11. This accurately detects the water shortage status in the water tank 2, improving the accuracy of the detection. Furthermore, since the water level sensor 12 can monitor the water level in the water storage box 11 in real time, when there is no water in the water tank 2, resulting in no water flowing into the water storage box 11, the water level sensor 12 can detect the absence of water in the water storage box 11 in real time, thereby improving the detection speed. Therefore, the water inlet circuit 1 provided by this utility model effectively solves the problem that existing cooking equipment cannot quickly and accurately determine the water shortage in the water tank 2.
[0041] Furthermore, the capacity of the water storage box 11 is smaller than the capacity of the water tank 2.
[0042] Specifically, the capacity of the water storage box 11 is smaller than that of the water tank 2. When all the water in the water tank 2 flows into the water storage box 11, it can prevent the situation where there is no water in the water tank 2 but there is still water in the water storage box 11.
[0043] It is understandable that by setting the capacity of the water storage box 11 to be smaller than that of the water tank 2, it can be ensured that when the water volume in the water tank 2 decreases to a certain level, the water flowing into the water storage box 11 can be drained in time to avoid water accumulation or residue. This allows for timely indirect detection of water shortage in the water tank 2 and triggering of an alarm signal. Therefore, this design makes the water inlet circuit 1 more sensitive to changes in the water volume in the water tank 2, effectively preventing dry burning.
[0044] Furthermore, please combine Figure 1 and Figure 2 As shown, the water level sensor 12 is attached to the side wall of the water storage box 11.
[0045] Specifically, the water level sensor 12 is connected to the side wall of the water storage box 11 in a close fit manner, which enables the water level sensor 12 to accurately sense the water level changes in the water storage box 11, reduces the error caused by air gaps or water evaporation, ensures that the detected water level signal data is accurate, improves the accuracy of detection, and also facilitates the installation and maintenance of the water level sensor 12.
[0046] Furthermore, the water inlet pipe 14 includes a first pipe 141, a second pipe 142, and a third pipe 143.
[0047] In one embodiment, one end of the first pipe 141 is connected to the water tank 2 of the cooking equipment, and the other end is connected to the water inlet of the water pump 13. One end of the second pipe 142 is connected to the water outlet of the water pump 13, and the other end is connected to the water storage box 11. One end of the third pipe 143 is connected to the water storage box 11, and the other end is connected to the evaporator 3 of the cooking equipment.
[0048] In another embodiment, one end of the first pipe 141 is connected to the water tank 2 of the cooking equipment, and the other end is connected to the water storage box 11. One end of the second pipe 142 is connected to the water storage box 11, and the other end is connected to the inlet of the water pump 13. One end of the third pipe 143 is connected to the outlet of the water pump 13, and the other end is connected to the evaporator 3 of the cooking equipment. This embodiment is described in detail using this method as an example. Please refer to [link / reference]. Figure 1 As shown, the first pipe 141 connects the water tank 2 and the storage tank 2, the second pipe 142 connects the storage tank 2 and the water inlet pump 13, and the third pipe 143 connects the water inlet pump 13 and the evaporator 3.
[0049] Specifically, water in water tank 2 can be drawn out and sent to water storage box 11 through any of the above embodiments. It can be understood that by setting up water inlet pump 13, either between water storage box 11 and evaporator 3, or between water tank 2 and water storage box 11, water in water tank 2 can be drawn out and sent to water storage box 11, realizing active control of water flow. This actively makes the water in water tank 2 flow into water storage box 11 and then into evaporator 3 more smoothly and efficiently, improving the stability and controllability of water flow from water tank 2, thereby improving the accuracy and reliability of water inlet circuit 1 in detecting water shortage in water tank 2.
[0050] Furthermore, please combine Figure 2 and Figure 3As shown, the water storage box 11 is provided with an inlet 111 and an outlet 112.
[0051] As one implementation method, this embodiment of the present invention will be described in detail using this method as an example. See reference [link / reference]. Figure 1 As shown, the water inlet 111 is connected to the first pipe 141 and is used to connect to the water tank 2 of the cooking equipment. The water outlet 112 is connected to the second pipe 142 and is connected to the water inlet of the water pump 13.
[0052] In another embodiment, the inlet 111 is connected to the second pipe 142 and to the outlet of the water pump 13, and the outlet 112 is connected to the third pipe 143 and is used to connect to the evaporator 3 of the cooking equipment.
[0053] Specifically, the height of the inlet 111 is higher than the height of the outlet 112.
[0054] It is understandable that by setting the height of the inlet 111 to be higher than that of the outlet 112, the inlet 111 is located at a higher position in the water storage box 11, while the outlet 112 is located at a lower position in the water storage box 11. This allows the water flowing out of the water tank 2 to flow into the water storage box 11 from a higher position and out from a lower position, which conforms to the flow direction of water under the action of gravity, thereby improving the sensitivity of detection and effectively preventing the risk of dry burning.
[0055] Specifically, the water outlet 112 is located near the bottom of the water storage box 11.
[0056] More specifically, the water outlet 112 is tangent to the bottom wall of the water storage box 11.
[0057] It is understandable that by setting the water outlet 112 near the bottom of the water storage box 11 and tangent to the bottom wall of the water storage box 11, it can be ensured that the water in the water storage box 11 can be quickly and completely drained when there is a lack of water, so that an alarm can be issued in time even when the water volume is very small, greatly improving the sensitivity of detection and further effectively preventing the risk of dry burning.
[0058] Example 2
[0059] The second embodiment of this utility model discloses a cooking device, which includes the water inlet channel 1 in the first embodiment. The function of the cooking device provided in the second embodiment of this utility model is the same as that of the water inlet channel 1 provided in the first embodiment, and will not be described again here.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
