Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a liquid heating container. Background Art

[0002] The liquid heating container usually includes an inner tank and a water outlet. The inner tank and the water outlet are connected through an outlet pipe. In order to facilitate users to collect water, the water outlet is generally opened downward, and the opening position is lower than the highest rated liquid level line of the inner tank. When the liquid level in the inner tank is higher than the opening, a siphon phenomenon will occur, causing the liquid in the inner tank to continuously flow out of the water outlet.

[0003] To solve this problem, some existing liquid heating containers have an air inlet pipe opening upward near the highest point of the water outlet pipe to destroy the siphon structure. However, the steam generated when the liquid is heated can easily enter the container through the air inlet pipe and cause damage to electrical components. Utility Model Content

[0004] The present application provides a liquid heating container, which can solve the problem in the prior art that high-temperature steam easily enters the interior of the container from the anti-siphon structure, causing damage to internal electrical components.

[0005] The present application provides a liquid heating container, comprising: an inner pot and a water outlet nozzle, the water outlet nozzle comprising a main body section and a water outlet section fixedly connected, the main body section comprising a tube body portion and a raised portion protruding radially outward along the tube body portion, the raised portion being connected to the tube body portion in a radial direction of the tube body portion; the top of the tube body portion is connected to the inner pot, and the bottom of the tube body portion is connected to the water outlet section; a connecting port is provided at the bottom end of the raised portion, and the raised portion is connected to the water outlet section through the connecting port; along the axial direction of the liquid heating container, the top end of the raised portion is higher than the rated maximum liquid level line of the inner pot.

[0006] In the above scheme, due to the presence of the raised portion, the liquid cannot fill the internal space of the tube body and the raised portion at the same time, that is, there is a portion of air in the internal space of the tube body and the raised portion, which changes the sealing of the liquid in the tube body, thereby reducing the pressure difference between the main section and the inner tank, achieving the effect of destroying the siphon, and preventing the liquid in the inner tank from continuing to flow to the water outlet due to the siphon effect. At the same time, the top of the raised portion is higher than the rated maximum liquid level line of the inner tank, that is, the top of the raised portion is always higher than the liquid level in the inner tank, so that there is no condition for the siphon phenomenon to occur between the water outlet and the inner tank, and the occurrence of the siphon phenomenon can be avoided. Compared with the method of destroying the siphon by setting an air inlet pipe with an upward opening at the highest point of the water outlet pipeline, the upper end of the water outlet provided in this embodiment is not connected to the outside world, which can prevent the steam generated when the liquid is heated from entering the interior of the liquid heating container, thereby reducing the risk of damage to internal electrical components.

[0007] Furthermore, a connecting port is provided at the bottom end of the raised portion, and the raised portion is connected to the water outlet section through the connecting port, and air can enter the raised portion through the connecting port. On the one hand, more air enters the raised portion, which can further reduce the pressure difference between the main section and the inner tank, and more offset the gravity of the liquid in the tube body, thereby further improving the anti-siphon effect; on the other hand, when the user takes water and the water outlet spout discharges water normally, if the liquid flow rate is too fast, the air pressure in the raised portion will be reduced, and the liquid in the tube body will not be able to flow out normally under the action of the external air pressure and will accumulate in the raised portion. The connecting port allows air to enter the raised portion, so that the air pressure in the raised portion is balanced with the external atmospheric pressure, ensuring that the liquid in the tube body flows normally to the water outlet section, improving the patency of the water outlet spout when discharging water, and preventing the problem of bacteria breeding caused by the accumulation of liquid in the raised portion, thereby improving the drinking water safety of the user.

[0008] In a possible design, along the protruding direction of the protruding portion, a protruding width L1 of the protruding portion satisfies: 3 mm ≤ L1 ≤ 7 mm.

[0009] In the above scheme, if L1 is too small, the internal space of the formed protrusion is small, which will lead to poor anti-siphon effect of the water outlet; if L1 is too large, the internal space of the formed protrusion is large, which is easy to accumulate liquid, causing the water outlet of the water outlet to be not smooth, affecting the user's experience. Therefore, when the protruding width L1 of the protrusion satisfies 3mm≤L1≤7mm, it can ensure that the water outlet has a good anti-siphon effect and ensure the smooth water outlet of the water outlet when the user takes water.

[0010] In a possible design, along the protruding direction of the protruding portion, the main body section has a size L2, and the water outlet section has a size L3, where L3>L2.

[0011] In the above solution, when L3>L2, the top of the water outlet section can wrap the bottom of the tube body and the raised part, and the liquid in the main section can flow directly to the water outlet section regardless of whether it flows out from the tube body or the raised part, thereby preventing the water outlet from leaking. At the same time, the water outlet section can guide all the liquid flowing out of the main section, reduce the risk of liquid escaping, and improve the stability of the water flow when the water outlet is discharged.

[0012] In a possible design, the tube body has an extension section, and the extension section is located in the water outlet section; along the axial direction of the liquid heating container, the length of the extension section is smaller than the length of the water outlet section.

[0013] In the above solution, the length of the tube body can be extended by providing the extension section, so that the water flowing out of the tube body is closer to the water outlet of the water outlet nozzle, which can reduce the risk of water flow escape and reduce the heat loss caused by water flow dispersion. The length of the extension section is shorter than the length of the water outlet section to ensure the wrapping effect of the water outlet section on the extension section, and the water outlet section can guide the liquid flowing out of the extension section.

[0014] In a possible design, a notch is provided on the side wall of the extension section, and along the radial direction of the extension section, the extension section is connected with the water outlet section through the notch; along the axial direction of the extension section, the top of the notch is connected with the connecting port.

[0015] In the above scheme, outside air can enter the tube body through the gap, so that the liquid in the tube body can flow along the inner wall of the tube body under the action of air pressure and its own surface tension, thereby improving the stability of the water flow, reducing the occurrence of liquid flowing out of the connecting port, and reducing the risk of liquid leakage.

[0016] In a possible design, in the axial direction of the liquid heating container, the diameter of the water outlet section gradually increases in a direction away from the protrusion.

[0017] In the above scheme, the structure of the water outlet section is trumpet-shaped with a narrow top and a wide bottom, which can increase the internal space of the water outlet section and increase the diameter of the water outlet nozzle, so that more air can enter the water outlet section more easily, which is beneficial to improving the anti-siphon effect of the water outlet nozzle.

[0018] In a possible design, along the axial direction of the liquid heating container, the length L4 of the water outlet section satisfies: L4≤25mm.

[0019] In the above scheme, when the length L4 of the water outlet section satisfies L4≤25mm, the heat loss during the liquid flow process can be reduced, ensuring that the temperature of the hot water flowing out of the water outlet is maintained at the temperature required by the user. At the same time, it can also reduce the risk of water flow escape and improve the water outlet smoothness of the water outlet.

[0020] In a possible design, the liquid heating container is further provided with a water pump and a water outlet pipe, the water pump is respectively connected to the inner tank and the water outlet pipe; the end of the water outlet pipe away from the water pump is connected to the pipe body.

[0021] In the above scheme, the water pump is connected to the bottom of the inner tank and is used to extract the liquid in the inner tank and send it into the water outlet through the water outlet pipe. The water pump is also used to increase the pressure of the liquid in the water outlet to speed up the flow of the liquid and ensure that the liquid flows smoothly to the outside.

[0022] In a possible design, the pipe body further has a connecting section, and the connecting section is connected to the water outlet pipe; the diameter of the connecting section matches the diameter of the water outlet pipe.

[0023] In the above scheme, the connecting section is used to connect to the water outlet pipe, and the diameter of the connecting section matches the diameter of the water outlet pipe, so that the liquid in the water outlet pipe can maintain its original flow state and flow smoothly into the water outlet nozzle, thereby improving the flow stability of the liquid and avoiding the problem of poor water flow due to changes in the pipe diameter.

[0024] In a possible design, the liquid heating container also includes an outer shell, and the inner tank and the water outlet are both installed in the outer shell; the outer wall of the water outlet section is provided with a fixing seat, and the fixing seat is fixedly connected to the outer shell.

[0025] In the above solution, the fixing seat and the housing can be fixedly connected by fasteners such as bolts, screws, pins, etc. to ensure the installation stability of the water outlet.

[0026] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0054] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0055] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0056] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0057] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0058] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a liquid heating container, including an outer shell 5 and an inner tank 1, a water outlet 2, a water pump 3 and a water outlet pipe 4 installed in the outer shell 5. The inner tank 1 is used to contain liquid; the water pump 3 is connected to the bottom of the inner tank 1 and the water outlet pipe 4 respectively, and the end of the water outlet pipe 4 away from the water pump 3 is connected to the water outlet 2. The water pump 3 sucks the liquid in the inner tank 1 and sends it to the water outlet 2 through the water outlet pipe 4, so that the liquid flows to the outside through the water outlet 2 for the user to drink. Among them, the water pump 3 is also used to increase the pressure of the liquid in the water outlet 2 to speed up the flow speed of the liquid and ensure that the liquid flows smoothly to the outside.

[0059] Among them, the materials of the inner tank 1, the water outlet nozzle 2 and the water outlet pipe 4 are all food-grade materials.

[0060] Specifically, Figure 3 As shown, the water outlet 2 includes a main body section 21 and a water outlet section 22 which are fixedly connected. The main body section 21 includes a tube body 211 and a protrusion 212 protruding outwardly along the radial direction X of the tube body 211. The protrusion 212 is in radial communication with the tube body 211. The top of the tube body 211 is connected to the water outlet pipeline 4 to communicate with the inner tank 1. The bottom of the tube body 211 is in communication with the water outlet section 22. The bottom of the water outlet section 22 is provided with a water outlet 222, which is in communication with the outside world through the water outlet 222. The liquid in the water outlet pipeline 4 flows into the water outlet section 22 through the tube body 211, and then flows to the outside world through the water outlet 222.

[0061] The inner tank 1 is provided with a rated maximum liquid level line to limit the maximum height of the liquid level in the inner tank 1 to prevent hot water from overflowing when the liquid is heated and boiled. The position of the water outlet 222 is lower than the rated maximum liquid level line of the inner tank 1, so that the water outlet 222 is closer to the cup tray 6 on the outer shell 5, reducing the risk of liquid splashing when the user receives water. Since the water pump 3 does not have a self-locking function, the inner tank 1 and the water outlet 2 are always in a connected state. When the liquid level in the inner tank 1 is higher than the water outlet 222, even if the water pump 3 is in a closed state, the liquid in the inner tank 1 will continue to flow to the water outlet 2 under the action of siphon.

[0062] like Figure 4 As shown, the tube body 211 includes a connecting section 211B and an intermediate section 211C. The connecting section 211B is located at the top of the tube body 211 and is used to connect with the water outlet pipe 4. The diameter of the connecting section 211B matches the diameter of the water outlet pipe 4, so that the liquid in the water outlet pipe 4 can maintain the original flow state and smoothly flow into the water outlet 2, thereby improving the flow stability of the liquid and avoiding the problem of poor water flow caused by the change of the pipe diameter. The intermediate section 211C is connected to the protrusion 212. Along the axial direction Z of the liquid heating container, the top of the protrusion 212 is higher than the rated maximum liquid level line of the inner pot 1.

[0063] Due to the presence of the raised portion 212, the liquid cannot fill the internal space of the middle section 211C and the raised portion 212 at the same time, that is, there is a portion of air in the internal space of the middle section 211C and the raised portion 212, which changes the sealing of the liquid in the middle section 211C, thereby reducing the pressure difference between the main section 21 and the inner tank 1, achieving the effect of destroying the siphon, and preventing the liquid in the inner tank 1 from continuing to flow to the water outlet 2 due to the siphon effect. At the same time, the top of the raised portion 212 is higher than the rated maximum liquid level line of the inner tank 1, that is, the top of the raised portion 212 is always higher than the liquid level height in the inner tank 1, so that the water outlet 2 and the inner tank 1 do not constitute the conditions for the occurrence of the siphon phenomenon, thereby avoiding the occurrence of the siphon phenomenon.

[0064] When the water pump 3 stops working, the liquid inside the water outlet 2 located above the protrusion 212 (located in the connecting section 211B) can flow back into the inner pot 1, and the liquid in the inner pot 1 will not continue to flow toward the water outlet 2. Moreover, air can enter the middle section 211C from the water outlet 222, and the air pressure and the gravity of the liquid inside the middle section 211C are offset. Even if some liquid cannot flow back into the inner pot 1 due to gravity, it will not flow out along the water outlet 222. Compared with the method of providing an air inlet pipe with an upward opening at the highest point of the water outlet pipeline 4 to destroy the siphon, the upper end of the water outlet 2 provided in this embodiment is not connected to the outside world, which can prevent the steam generated when the liquid is heated from entering the interior of the liquid heating container, thereby reducing the risk of damage to internal electrical components.

[0065] Furthermore, if Figure 4 and Figure 5 As shown, a communication port 212A is provided at the bottom end of the protrusion 212 , and the protrusion 212 is connected to the water outlet section 22 through the communication port 212A, and air can enter the protrusion 212 through the communication port 212A. On the one hand, more air enters the raised portion 212, which can further reduce the pressure difference between the middle section 211C and the inner tank 1, and more offset the gravity of the liquid in the middle section 211C, thereby further improving the anti-siphon effect; on the other hand, when the user takes water and the water outlet 2 discharges water normally, if the liquid flow rate is too fast, the air pressure in the raised portion 212 will decrease, and the liquid in the middle section 211C will not be able to flow out normally under the action of the external air pressure and will accumulate in the raised portion 212. The connecting port 212A allows air to enter the raised portion 212, so that the air pressure in the raised portion 212 is balanced with the external atmospheric pressure, ensuring that the liquid in the middle section 211C flows normally to the water outlet 222, thereby improving the patency of the water outlet 2 when discharging water, and preventing the problem of bacteria breeding caused by the accumulation of liquid in the raised portion 212, thereby improving the drinking water safety of the user.

[0066] In addition, if Figure 4 As shown, the middle section 211C is a uniform structure with a constant diameter, and its diameter is equal to the diameter of the connecting section 211B. When the water outlet 2 discharges water, the water flow is not easy to escape in the connecting section 211B and the middle section 211C, which can improve the stability of the water outlet 2 when discharging water and avoid the phenomenon of intermittent water flow.

[0067] like Figure 4 As shown, in a specific embodiment, along the protruding direction X of the protruding portion 212, the protruding width L1 of the protruding portion 212 satisfies: 3mm≤L1≤7mm. L1 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm or 6mm, or other values ​​within the above range, which is not limited in the present application.

[0068] If L1 is too small (for example, less than 3 mm), the internal space of the raised portion 212 is small, resulting in a poor anti-siphon effect of the water outlet 2; if L1 is too large (for example, greater than 7 mm), the internal space of the raised portion 212 is large, which is easy to accumulate liquid, causing the water outlet 2 to be not smooth, affecting the user's experience.

[0069] Therefore, when the protruding width L1 of the protruding portion 212 satisfies 3mm≤L1≤7mm, it can ensure that the water outlet 2 has a good anti-siphon effect and can ensure smooth water flow from the water outlet 2 when the user takes water.

[0070] like Figure 4As shown, in a specific embodiment, along the protruding direction X of the protruding portion 212, the main body section 21 has a size L2, and the water outlet section 22 has a size L3, and L3>L2. L2 is the size of the space formed by the tube body 211 and the protruding portion 212 in the protruding direction X of the protruding portion 212, and L3 is the inner diameter of the water outlet section 22.

[0071] When L3>L2, the top of the water outlet section 22 can wrap the bottom of the tube body 211 and the protrusion 212, and the liquid in the main section 21 can flow directly into the water outlet section 22, whether it flows out from the tube body 211 or the protrusion 212, to prevent the water outlet 2 from leaking. At the same time, the water outlet section 22 can guide all the liquid flowing out of the main section 21, reduce the risk of liquid escaping, and improve the stability of the water flow when the water outlet 2 is discharged.

[0072] like Figure 4 As shown, in a specific embodiment, the tube body 211 has an extension section 211A, and the extension section 211A is located in the water outlet section 22; along the axial direction Z of the liquid heating container, the length of the extension section 211A is less than the length of the water outlet section 22.

[0073] The diameter of the extension section 211A is consistent with that of the middle section 211C and the connection section 211B. By providing the extension section 211A, the length of the tube body 211 can be extended, so that the water flowing out of the tube body 211 is closer to the water outlet 222, which can reduce the risk of water flow escape, prevent splashing when the liquid flows out of the water outlet 222, and reduce the heat loss caused by water flow dispersion. The length of the extension section 211A is less than the length of the water outlet section 22 to ensure that the water outlet section 22 wraps the extension section 211A, and the water outlet section 22 can guide the liquid flowing out of the extension section 211A.

[0074] Specifically, Figure 4 and Figure 5 As shown, the side wall of the extension section 211A is provided with a notch 211Aa. Along the radial direction X of the extension section 211A, the extension section 211A is connected with the water outlet section 22 through the notch 211Aa. Along the axial direction Z of the extension section 211A, the top of the notch 211Aa is connected with the connecting port 212A.

[0075] External air can enter the tube body 211 through the notch 211Aa, so that the liquid in the tube body 211 can flow along the inner wall of the tube body 211 under the action of air pressure and its own surface tension, thereby improving the stability of the water flow, reducing the occurrence of liquid flowing out of the connecting port 212A, and reducing the risk of liquid leakage.

[0076] like Figure 4As shown, in a specific embodiment, in the axial direction Z of the liquid heating container, the diameter of the water outlet section 22 gradually increases in the direction away from the protrusion 212. That is, the structure of the water outlet section 22 is a trumpet shape with a narrow top and a wide bottom, which can increase the internal space of the water outlet section 22 and increase the diameter of the water outlet 222, so that more air can enter the water outlet section 22 more easily, which is conducive to improving the anti-siphon effect of the water outlet 2.

[0077] like Figure 4 As shown, in a specific embodiment, along the axial direction Z of the liquid heating container, the length L4 of the water outlet section 22 satisfies: L4≤25mm. L4 can be 5mm, 10mm, 15mm, 20mm or 25mm, or other values ​​within the above range, which is not limited in the present application.

[0078] If L4 is too large (for example, greater than 25 mm), the liquid flow path in the water outlet section 22 is too long, which will cause the temperature of the liquid flowing out of the water outlet 222 to decrease, resulting in a poor user experience. In addition, since the water outlet section 22 is trumpet-shaped, if the length is too long, the water flow will be too dispersed, which will cause the water outlet 2 to not flow smoothly.

[0079] Therefore, when the length L4 of the water outlet section 22 satisfies L4≤25mm, the heat loss during the liquid flow process can be reduced, ensuring that the temperature of the hot water flowing out of the water outlet 2 is maintained at the temperature required by the user. At the same time, it can also reduce the risk of water flow escape and improve the water outlet smoothness of the water outlet 2.

[0080] like Figure 3 As shown, in a specific embodiment, the outer wall of the water outlet section 22 is provided with a fixing seat 221, and the fixing seat 221 is fixedly connected to the housing 5. The fixing seat 221 and the housing 5 can be fixedly connected by fasteners such as bolts, screws, and pins to ensure the installation stability of the water outlet 2. Specifically, two fixing seats 221 can be symmetrically provided on the outer wall of the water outlet section 22 along the radial direction X of the water outlet 2 to make the installation of the water outlet 2 more stable and reliable.

[0081] like Figure 3 and Figure 4 As shown, the outer wall of the water outlet section 22 is further provided with a limiting portion 222, and the limiting portion 222 is arranged around the circumference of the water outlet section 22. Figure 5 As shown, the limiting portion 222 is used to limit the outer shell 5 in the axial direction Z of the liquid heating container to prevent the water outlet 2 from escaping from the outer shell 5.

[0082] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
