[0004] The problem this invention aims to solve is that scale easily forms in the heating area of ​​a water tank, making it difficult to clean.

[0005] To address the aforementioned problems, in a first aspect, this utility model provides a heated water tank, comprising a tank body, a water tank, and a temperature detection component. The water tank is detachably installed on the tank body, a heat-conducting plate is mounted on the water tank, and a heat-conducting connector is mounted on the heat-conducting plate. An electric heating element is provided on the tank body, and the electric heating element is detachably connected to the heat-conducting connector. The temperature detection component is located in the tank body and the water tank, and is used to detect the temperature of the heat-conducting plate.

[0006] Optionally, the housing is provided with an installation cavity, the water tank is slidably installed in the installation cavity, and can be pulled out from the installation cavity along the length of the water tank. The housing and the water tank are also provided with a fixing component, which is used to fix the water tank after it is slidably installed.

[0008] Optionally, the outer bottom wall of the water tank is provided with a heat insulation plate, and the heat-conducting plate is partially exposed outside the outer bottom wall of the water tank. The heat insulation plate is used to isolate the exposed part of the heat-conducting plate from the outside.

[0009] Optionally, the heat-conducting plate is partially exposed above the inner bottom wall of the water tank, and the surface of the exposed portion is provided with an anti-stick coating.

[0010] Optionally, the temperature detection assembly includes a temperature detection channel and a temperature detection element. The temperature detection channel is disposed on the heat-conducting plate and is arranged parallel to the heat-conducting docking component. The temperature detection element is disposed on the housing and is plugged into the temperature detection channel.

[0011] Optionally, the temperature detection assembly includes a temperature detection channel and a temperature detection element. The temperature detection channel is disposed on the heat-conducting plate and is arranged parallel to the heat-conducting docking component. The temperature detection element is disposed on the housing and is plugged into the temperature detection channel.

[0012] Optionally, the water tank includes a heating chamber and a water storage chamber separated by a partition, the heat-conducting plate is disposed in the heating chamber, and the partition is provided with water holes for connecting the heating chamber and the water storage chamber.

[0015] The heating water tank provided by this utility model has the following advantages: By setting up a tank body and a water tank, the water tank is detachably installed in the tank body, and a heat-conducting plate is installed on the water tank. The water tank can be installed and removed from the tank body, for example, by being pulled out and inserted. After installation, the electric heating element contacts the heat-conducting connector. The heat-conducting connector and the heat-conducting plate form a connected heat-conducting whole. Therefore, after the heat-conducting connector and the electric heating element are connected, heat can be conducted to the heat-conducting plate. When the heat-conducting plate is in contact with the water in the water tank, it can directly heat the water. The electric heating element achieves heating through the heat-conducting function of the heat-conducting connector and the heat-conducting plate. Heating the water in the tank avoids direct contact between the electric heating element and the water, reducing scale buildup to some extent. Furthermore, the planar structure of the heat-conducting plate makes cleaning easier. When the tank detaches from the housing, the heat-conducting connector separates from the electric heating element, stopping the heating of the heat-conducting plate. Since both the housing and the tank are equipped with a temperature detection component, the heating temperature of the heat-conducting plate can be detected. Based on the detected temperature, water can be added manually in a timely manner to prevent overheating and dry burning of the heat-conducting plate. This also ensures the water in the tank is heated to the appropriate target temperature.

[0016] Secondly, this utility model also provides a baby crib, including a heating water tank as described in any of the preceding claims.

[0017] The baby crib provided by this utility model has the same beneficial effects as the heating water tank compared to the prior art, and will not be described again here. Attached Figure Description

It should be noted that the aforementioned representations of the Z, Y, and X axes are merely for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0031] Reference Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a heating water tank, which includes a tank body 1, a water tank 2, and a temperature detection component. The water tank 2 is detachably installed on the tank body 1, and a heat-conducting plate 8 is installed on the water tank 2. A heat-conducting connector 11 is installed on the heat-conducting plate 8. An electric heating element 16 is provided on the tank body 1, and the electric heating element 16 is detachably connected to the heat-conducting connector 11. The temperature detection component is located inside the tank body 1 and is used to detect the temperature of the heat-conducting plate 8.

[0032] Specifically, in use, the heating water tank of this utility model is generally used as a whole, with the water tank 2 and the tank body 1 forming a crib structure. As a heating water tank structure, the water tank 2 can be detached from the tank body 1 for overall cleaning and maintenance. Since the water tank 2 is detachably installed on the tank body 1, and the electric heating element 16 is detachably connected to the heat-conducting connector 11, the connection between the electric heating element 16 and the heat-conducting connector 11 can be configured to be synchronized with the installation of the water tank 2 and the tank body 1, for example, both in the same direction. The heat-conducting connector 11 and the heat-conducting plate 8 are connected as a whole. After the heat-conducting connector 11 and the electric heating element 16 are connected, heat can be conducted to the heat-conducting plate 8. The heat-conducting plate 8 is placed in the water tank 2 and can directly contact the water, thereby heating the water in the water tank 2. The temperature detection component can detect the heating temperature of the heat-conducting plate 8. Based on the detected heating temperature, water can be added in time (manually) to avoid overheating of the heat-conducting plate 8 by dry burning. It can also heat the water in the water tank 2 to a suitable target temperature.

[0033] In practical application, the heating water tank in this embodiment includes a tank body 1 and a water tank 2. The water tank 2 is detachably installed on the tank body 1, and a heat-conducting plate 8 is installed on the water tank 2. The water tank 2 can be installed and removed from the tank body 1, for example, by being pulled out and inserted. After installation, the electric heating element 16 contacts the heat-conducting connector 11. The heat-conducting connector 11 and the heat-conducting plate 8 form a connected heat-conducting unit. After the heat-conducting connector 11 and the electric heating element 16 are connected, heat can be transferred to the heat-conducting plate 8. The heat-conducting plate 8, in contact with the water in the water tank 2, can directly heat the water. The electric heating element 16 achieves heating through the heat-conducting functions of the heat-conducting connector 11 and the heat-conducting plate 8. Heating the water in the water tank 2 avoids direct contact between the electric heating element and the water, reducing scale buildup to some extent. Furthermore, the planar structure of the heat-conducting plate 8 makes cleaning easier. When the water tank 2 detaches from the housing 1, the heat-conducting connector 11 separates from the electric heating element 16, stopping the heating of the heat-conducting plate 8. Since both the housing 1 and the water tank 2 are equipped with a temperature detection component, the heating temperature of the heat-conducting plate 8 can be detected. Based on the detected temperature, water can be added manually in a timely manner to prevent overheating of the heat-conducting plate 8 and to heat the water in the water tank 2 to a suitable target temperature.

[0034] It should be noted that the heat-conducting plate 8 can be configured as an aluminum block, the heat-conducting connector 11 can be configured as a copper sleeve, and the electric heating element 16 can be configured as a resistor with an outer aluminum sleeve. The heat-conducting connector 11 and the electric heating element 16 are made of different materials, which can prevent the aluminum parts from sticking to each other when they are tightly fitted during heating.

[0035] like Figure 1 , Figure 3, Figure 4 , Figure 5 and Figure 7 As an optional embodiment of this utility model, the housing 1 is provided with a mounting cavity 3, and the water tank 2 is slidably mounted in the mounting cavity 3, and can be mounted along the length direction of the water tank 2 ( Figure 1 The water tank 2 is pulled out from the mounting cavity 3 in the X-axis direction. The housing 1 and the water tank 2 are also provided with a fixing component, which is used to fix the water tank 2 after it is slidably installed.

[0036] Specifically, the installation cavity 3 is opened from the side of the box 1, so the entire water tank 2 can be directly pulled out from the side of the box 1. A handle can be provided on the side of the water tank 2. After being pulled out directly, the electric heating element 16 and the heat conduction plate 8 are disengaged, and heating stops.

[0037] Of course, in some cases, if the water tank 2 is set along the height of the tank 1, it can be pulled out from the top of the tank 1.

[0038] For the fixing component, the fixing component includes a second magnetic suction member 17 installed on the inner wall of the mounting cavity 3 and a first magnetic suction member 14 installed on the water tank 2. The positions of the first magnetic suction member 14 and the second magnetic suction member 17 are arranged correspondingly. That is, when the water tank 2 is slidably installed, the first magnetic suction member 14 contacts the second magnetic suction member 17, thereby fixing the water tank 2 on the box body 1. The second magnetic suction member 17 and the first magnetic suction member 14 are magnets. Preferably, the first magnetic suction member 14 is a hollow magnet. The first magnetic suction member 14 is provided with a magnetic flux switch. When the first magnetic suction member 14 and the second magnetic suction member 17 are close enough, the magnetic flux switch (its internal state changes due to the magnetic force of the second magnetic suction member 17) sends a magnetic flux signal to the controller of the water tank. At this time, the controller can control the start of heating.

[0039] As an optional embodiment of this utility model, the outer bottom of the water tank 2 is provided with an extension 7, and the mounting cavity 3 is provided with a track that cooperates with the extension 7.

[0040] In practical application, the extension 7 is provided with a side part along the length direction of the water tank 2, and the extension 7 slides with the track, thereby ensuring the smoothness of the water tank 2 sliding out or being inserted from the box 1.

[0041] like Figure 2 , Figure 3 and Figure 6 As shown, in an optional embodiment of the present invention, the heat-conducting plate 8 is embedded and installed along the inner bottom wall of the water tank 2 and extends to the outer bottom wall of the water tank 2. A sealing element is provided between the heat-conducting plate 8 and the water tank 2. The heat-conducting connecting part 11 is arranged along the length direction of the water tank 2. The heat-conducting connecting part 11 is inserted and engaged with the electric heating element 16.

[0042] For example, the heat-conducting connector 11 is a tubular structure and the electric heating element 16 is a rod-shaped structure. After the electric heating element 16 is inserted into the heat-conducting connector 11, it can conduct heat to the heat-conducting plate 8.

[0043] Specifically, the heat-conducting plate 8 is embedded in the water tank 2, enabling contact heating of the water. It extends to the outer bottom of the water tank 2 and can cooperate with the heat-conducting connector 11 to avoid affecting the internal space of the water tank 2. The heat-conducting connector 11 is plugged into the electric heating element 16, preferably with a clearance fit. The electric heating element 16 is connected to the circuit inside the housing 1. The circuit includes a power supply and a switch (not shown in the figure, but the circuit itself is a common circuit in the prior art). The heat-conducting connector 11 is arranged along the length of the water tank 2, and the shape of the mounting cavity 3 is adapted to the water tank 2. Thus, when the water tank 2 is pulled out of the housing 1 along the length of the water tank 2, the electric heating element 16 and the heat-conducting connector 11 are no longer in contact, and the seal can achieve waterproofing.

[0044] like Figure 6 As shown, in an optional embodiment of the present invention, the outer bottom wall of the water tank 2 is provided with a heat insulation plate 9, and the heat conducting plate 8 is partially exposed on the outer bottom wall of the water tank 2. The heat insulation plate 9 is used to isolate the exposed part of the heat conducting plate 8 from the outside.

[0045] Specifically, the heat-conducting plate 8 has a certain thickness and volume to ensure sufficient contact surface with the water in the water tank 2, and also to ensure that the heat-conducting connector 11 cooperates with the electric heating element 16 to conduct heat. The heat-conducting plate 8 is extended to the bottom of the water tank 2. In this way, it will not affect the internal space of the water tank 2. At the same time, in order to prevent the risk of scalding when the water tank 2 is pulled out, or to prevent damage to the base of the box 1 when it is inside the box 1, a heat insulation plate 9 is installed at the bottom of the water tank 2, that is, at the bottom of the heat-conducting plate 8, to achieve the function of heat insulation. The bottom volume of the heat insulation plate 9 is similar to that of the bottom of the heat-conducting plate 8, and it can be installed at the bottom of the water tank 2 at the same time as the heat-conducting plate 8 by bolts.

[0046] like Figure 2 As shown, in an optional embodiment of the present invention, the heat-conducting plate 8 is partially exposed above the inner bottom wall of the water tank 2, and the surface of the exposed portion is provided with an anti-stick coating 13.

[0047] Specifically, the top of the heat-conducting plate 8 is exposed above the inner bottom wall of the water tank 2. The exposed part can be used to directly contact water and heat the water. The surface of the exposed part is provided with at least one layer of anti-stick coating 13. The anti-stick coating 13 can be an anti-stick material, such as Teflon, thereby preventing (or reducing) the adhesion of scale and further avoiding the problem of the surface of the heat-conducting plate 8 being difficult to clean. Moreover, Teflon material can have good thermal conductivity and has little or no impact on heating.

[0048] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in an optional embodiment of the present invention, the temperature detection component includes a temperature detection channel 12 and a temperature detection element 15. The temperature detection channel 12 is disposed on the heat-conducting plate 8 and is arranged parallel to the heat-conducting docking part 11. The temperature detection element 15 is disposed on the housing 1 and is plugged into the temperature detection channel 12.

[0049] Specifically, since the temperature detection channel 12 is arranged parallel to the heat-conducting docking piece 11, and the temperature detection piece 15 is inserted into the temperature detection channel 12, after the water tank 2 is slidably installed on the mounting cavity 3 along its length and is in place, the temperature detection piece 15 is inserted into the temperature detection channel 12, thereby enabling monitoring of the temperature of the heat-conducting plate 8. The housing 1 is also equipped with a detection circuit (not shown in the figure) electrically connected to the temperature detection piece 15, which may include a controller, a switch, and a power supply. The temperature detection piece 15 is electrically connected to the controller, thereby achieving heating at the target temperature. The temperature detection piece 15 is a temperature control probe that directly detects the heat conduction. The temperature of the heat-conducting plate 8 is basically consistent with the temperature of the water in the water tank 2 (and will not exceed 100 degrees when there is water). When there is a lack of water in the water tank 2, the temperature of the heat-conducting plate 8 will rise above 100 degrees, for example, it can reach 115 degrees. This can serve as a water shortage alarm (the main controller can be connected to the alarm component) to avoid false alarms of water shortage. The temperature detection component can detect the heating temperature of the heat-conducting plate 8 and then determine whether to activate the heat-conducting docking component 11 to prevent the heat-conducting plate 8 from overheating and ensure that the heat-conducting plate 8 itself will not exceed the temperature. It can also work with the controller to ensure that the water in the water tank 2 is heated to the appropriate target temperature.

[0050] like Figure 4 and Figure 5 As shown, in an optional embodiment of the present invention, the water tank 2 includes a heating chamber 21 and a water storage chamber 22 separated by a partition 4. The heat-conducting plate 8 is disposed in the heating chamber 21, and the partition 4 is provided with a water hole 6 for connecting the heating chamber 21 and the water storage chamber 22.

[0051] Specifically, the heating chamber 21, the water storage chamber 22, and the water hole 6 form a communicating vessel. Under normal circumstances, the water in the heating chamber 21 can be used directly. The water in the heating chamber 21 can be heated and passed to other parts of the crib or scooped out or drained. The water storage chamber 22 is used to store water. After the water in the heating chamber 21 is used up, the required water can be automatically supplied to the heating chamber 21.

[0052] like Figure 5 and Figure 8As shown, in an optional embodiment of the present invention, a barrier 18 is detachably installed on the side of the separator 4 facing the water storage chamber 22, and the barrier 18 covers the water hole 6.

[0053] Specifically, two guide strips 5 are symmetrically fixed on the side of the separator 4 facing the water storage chamber 22. The cross-section of the guide strip 5 is T-shaped, and the cross-section of the barrier 18 is concave. This structure covers the water hole 6 and is broken in the middle (the broken part contacts the separator 4), so that the barrier 18 is embedded along the top and bottom of the two guide strips 5. There is a gap between the bottom of the barrier 18 and the inner bottom wall of the water tank 2 (actually the water storage chamber 22). The water with a lower temperature in the water storage chamber 22 can pass through this gap and then enter the heating chamber 21 through the water hole 6, thereby exchanging heat with the water with a higher temperature in the heating chamber 21. The above arrangement ensures that there are two layers of separation (separator 4 and barrier 18) between the water in the heating chamber 21 and the water in the water storage chamber 22, ensuring that only the water with a smaller volume in the heating chamber 21 is heated in a short time, and ensuring that the electric heating element 16 can quickly heat the water in the heating chamber 21 with low power.

[0054] like Figure 6 As shown, in an optional embodiment of the present invention, the sealing element includes a sealing ring 10, and a gap is provided between the outer periphery of the heat-conducting plate 8 and the inner bottom wall of the water tank 2, and the sealing ring 10 is used to seal the gap.

[0055] Specifically, the sealing ring 10 is set as an elastic sealing ring, such as a silicone sealing ring, and is set along the periphery of the heat-conducting plate 8. Since the top of the heat-conducting plate 8 is exposed, there is a certain gap between it and the bottom of the water tank 2. The sealing ring 10 is set between the heat-conducting plate 8 and the water tank 2 for waterproofing and to achieve a good sealing effect.

[0056] This utility model also provides a baby crib, including a heating water tank as described in any of the above embodiments.

[0057] The specific implementation method of this embodiment can be referred to the corresponding implementation method described above, and will not be described again here.

[0058] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features of the present invention.

[0059] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
