Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and in particular to a heating device, a bubble water machine, and a method of using it. Background Technology

[0002] Sparkling water is a carbonated beverage made by injecting carbon dioxide into water under pressure. It is typically produced using a sparkling water machine, which injects carbon dioxide into a sealed water bottle via a gas cylinder to mix with water.

[0003] According to existing technology, there is a type of sparkling water machine, with publication number CN222929597U. A heating inlet pipe is connected to the water tank, and an instant heating module is connected to the heating inlet pipe. The instant heating module is also connected to a heating outlet pipe. A heating delivery pump is installed on the heating inlet pipe. The delivery pump delivers water from the purified water tank to the instant heating module. The water is heated by the instant heating module and comes out from the heating outlet pipe. During heating, water vapor enters the water outlet through the heating outlet pipe. The water vapor condenses at the water outlet, causing dripping. This not only wastes water resources but also affects the environment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a heating device, a bubble water machine and a method of use that prevents water from dripping from the spout when producing hot water.

[0005] To achieve the above objectives, the technical solution of the present invention is: a heating device, comprising a water tank having a receiving cavity for containing water, wherein the water tank has a first end and a second end along the axial direction of the water tank.

[0006] The receiving cavity is provided with a partition, which divides the receiving cavity into a first cavity located at the first end of the water tank and a second cavity located at the second end of the water tank, and the first cavity and the second cavity are connected.

[0007] The water tank is equipped with a hot water pipe at the first end, and the inlet end of the hot water pipe extends into the first cavity; when heating the water in the second cavity, the water in the second cavity enters the first cavity to seal the inlet end of the hot water pipe.

[0008] With the above structure, the present invention has the following advantages compared with the prior art: the water tank has a water-containing cavity, which is used to heat the water in the cavity. The cavity is divided by a partition to form a first cavity and a second cavity that are interconnected. At the same time, the inlet end of the hot water pipe is located in the first cavity, and the water in the second cavity enters the first cavity to seal the inlet end of the hot water pipe. In this way, when heating, water vapor will not enter the outlet from the inlet end of the hot water pipe through the hot water pipe, thus preventing water from dripping from the outlet.

[0009] Preferably, the surface of the partition is provided with a water passage hole, which connects the first cavity and the second cavity. The inlet end of the hot water pipe covers the water passage hole of the partition, and the water in the second cavity enters the hot water pipe through the water passage hole, so that the hot water in the second cavity can flow into the hot water pipe through the water passage hole.

[0010] Preferably, the hot water pipe has an inlet hole on its side at the inlet end. Water in the hot water pipe enters the first cavity through the inlet hole, which facilitates the hot water in the hot water pipe to enter the first cavity through the inlet hole. This also allows the water in the first cavity to seal the inlet hole, preventing water vapor in the first cavity from entering the hot water pipe through the inlet hole.

[0011] Preferably, the number of water inlets is one or more, and the water inlets are distributed along the circumferential direction of the hot water pipe to increase the water output speed.

[0012] Preferably, the surface of the partition facing the first cavity is provided with a positioning groove, and the water inlet end of the hot water pipe is located in the positioning groove, which facilitates the positioning of the hot water pipe.

[0013] Preferably, the water tank includes:

[0014] The box body is hollow along the axial direction of the box body, and the partition is provided inside the box body;

[0015] A cover plate is sealed to the first end of the housing. The first cavity consists of the cover plate, the inner side of the first end of the housing, and a partition.

[0016] The bottom plate is sealed to the second end of the box. The second cavity consists of the bottom plate, the inner side of the second end of the box, and the partition. This facilitates the installation of the hot water pipe in the first cavity and the installation of the heating element in the second cavity.

[0017] A sparkling water machine includes a heating device as described in any of the above claims, and further includes a water outlet, wherein the outlet end of the hot water pipe is connected to the water outlet.

[0018] Preferably, the first end of the water tank is also provided with a hot water return port, and the two ends of the hot water return pipe are respectively connected to the hot water return port and the water outlet to recover the water vapor in the water outlet and prevent the water vapor from condensing in the water outlet.

[0019] Preferably, it also includes a connecting pipe, the two ends of which are connected to the hot water pipe outlet and the water outlet, respectively. The connecting pipe is L-shaped with the opening facing downwards, which facilitates drainage by utilizing the siphon effect.

[0020] A method of use, applied to any of the above-described sparkling water machines, includes the following steps:

[0021] S1: The pump is used to deliver the water to be heated to the second chamber through the inlet pipe;

[0022] S2: When the water level in the first chamber exceeds the inlet hole, the water seals the inlet hole, and the pump stops pumping.

[0023] S3: The heating element heats the water in the second chamber;

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Figure 1 This is a front sectional view of a heating device according to the present invention, such as... Figure 1In the illustrated embodiment, the present invention provides a heating device, including a water tank 1 with a receiving cavity 2 for containing water. The water tank 1 has a first end and a second end along the axial direction of the water tank 1. A partition 3 is provided inside the receiving cavity 2, dividing the receiving cavity 2 into a first cavity 210 located at the first end of the water tank 1 and a second cavity 220 located at the second end of the water tank 1. The first cavity 210 and the second cavity 220 are interconnected. In addition, a hot water pipe 4 is provided at the first end of the water tank 1. The inlet end of the hot water pipe 4 extends into the first cavity 210, and the outlet end of the hot water pipe 4 passes through the first end of the water tank 1 and communicates with a water outlet 5. When heating the water in the second cavity 220, the water in the second cavity 220 enters the first cavity 210 and seals the inlet end of the hot water pipe 4. In this way, water vapor will not enter the water outlet 5 from the inlet end of the hot water pipe 4 through the hot water pipe 4, thus preventing water dripping from the water outlet 5. Specifically, a heating element is provided in the second cavity 220 for heating the water inside the second cavity 220 by energizing the heating element. Specifically, the heating element can be a heating wire or a heating tube.

[0036] Specifically, in this embodiment, the first end is the upper end and the second end is the lower end.

[0037] As one embodiment, the surface of the partition 3 is provided with a water passage hole 320, which connects the first cavity 210 and the second cavity 220. The water inlet end of the hot water pipe 4 is covered by the water passage hole 320 of the partition 3. Water in the second cavity 220 enters the hot water pipe 4 through the water passage hole 320, so that the hot water in the second cavity 220 can flow into the hot water pipe 4 through the water passage hole 320.

[0038] Furthermore, a water inlet hole 410 is provided on the side of the water inlet end of the hot water pipe 4. Water in the hot water pipe 4 enters the first cavity 210 through the water inlet hole 410, which facilitates the hot water in the hot water pipe 4 to enter the first cavity 210 through the water inlet hole 410. This also facilitates the water in the first cavity 210 to seal the water inlet hole 410, preventing water vapor in the first cavity 210 from entering the hot water pipe 4 through the water inlet hole 410.

[0039] As one embodiment, the surface of the partition 3 facing the first cavity 210 is provided with a positioning groove 310, and the water inlet end of the hot water pipe 4 is located in the positioning groove 310, which facilitates the positioning of the hot water pipe 4 and the installation of the hot water pipe 4.

[0040] Figure 3 This is a perspective view of a hot water pipe in a heating device according to the present invention, as shown below. Figure 3 In the illustrated embodiment, the number of water inlet holes 410 is one or more, and the water inlet holes 410 are distributed along the circumference of the hot water pipe to increase the water flow rate. In this embodiment, the number of water inlet holes 410 is four, and the water inlet holes 410 are distributed along the circumference of the hot water pipe.

[0041] Preferably, the water inlet hole 410 extends through the end face of the water inlet pipe 4 in the direction of the second cavity 220, which is convenient for processing and also makes the size of the water inlet hole 410 larger, with a larger water outlet area, so that the hot water in the hot water pipe 4 can flow quickly into the first cavity 210 to seal the hot water pipe 4, so that water vapor can enter the water outlet 5 through the water inlet end of the hot water pipe 4.

[0042] Figure 4 This is a perspective view of a heating device according to the present invention. Figure 5 This is a front sectional view of the housing of a heating device according to the present invention. Figure 6 A perspective view of a heating device cover plate according to the present invention, as shown below. Figure 4 , 5 In the embodiment shown in Figure 6, the water tank 1 includes a tank body 110, a cover plate 120, and a bottom plate 130; the tank body 110 is hollow along the axial direction of the tank body 110, and the partition 3 is disposed inside the tank body 110; the cover plate 120 is sealed to the first end of the tank body 110, and the first cavity 210 is composed of the top surface of the cover plate 120, the inner side of the first end of the tank body 110, and the surface of the partition 3; the bottom plate 130 is sealed to the second end of the tank body 120, and the second cavity 220 is composed of the upper surface of the bottom plate 130, the inner side of the second end of the tank body 110, and the surface of the partition 3, which facilitates the installation of the hot water pipe 4 in the first cavity 210 and also facilitates the installation of the heating element in the second cavity 220.

[0043] As one embodiment, a water inlet pipe 111 is provided on the outer side of the housing 110 at a position corresponding to the second cavity 220. The water inlet pipe 111 is connected to the second cavity 220, so that the water to be heated can be delivered into the second cavity 220 by a pump.

[0044] As one embodiment, a level gauge is provided in the housing 110 at the position corresponding to the first cavity 210, so that the liquid level can be observed.

[0045] Figure 7 This is a perspective view of a heating device of the present invention applied to a sparkling water machine, as shown. Figure 7 In the illustrated embodiment, the present invention also provides a sparkling water machine, including a heating device as described in any of the preceding claims. It further includes a water outlet 5, with the outlet end of the hot water pipe 4 connected to the water outlet 5. Hot water in the second chamber 220 flows to the water outlet 5 through the hot water pipe 4.

[0046] As one embodiment, the first end of the water tank 1 is also provided with a hot water return port 6. The two ends of the hot water return pipe are respectively connected to the hot water return port 6 and the water outlet 5, to recover water vapor in the water outlet 5 and prevent water vapor from condensing in the water outlet 4. Specifically, the hot water return pipe is L-shaped with the opening facing downwards. The length of the end of the hot water return pipe facing the water tank 1 is greater than the length of the end of the hot water return pipe facing the water outlet 5. This facilitates the recovery of water vapor in the water outlet 5 into the first cavity 210 through the hot water return pipe, and also prevents water vapor in the first cavity 210 from flowing into the water outlet 5 through the hot water return pipe. Specifically, the longer length of the end of the hot water return pipe facing the water tank 1 causes water vapor to condense in the end of the hot water return pipe facing the water tank 1, while the shorter length of the end of the hot water return pipe facing the water outlet 5 allows water vapor in the water outlet 5 to flow quickly to the end of the hot water return pipe facing the water tank 1 and condense.

[0047] Figure 8 This is a perspective view of the connection between the water tank and the water outlet of a heating device according to the present invention, as shown below. Figure 8 In the illustrated embodiment, it also includes a connecting pipe 7, with its two ends connected to the outlet end of the hot water pipe 4 and the water outlet 5, respectively. The connecting pipe 7 is L-shaped with its opening facing downwards, facilitating drainage using the siphon effect. During heating, a pump delivers the water to be heated into the second chamber 220. The water flows sequentially through the water passage 320 and the water inlet 410 into the first chamber 210. The water inlet 410 is sealed to prevent water vapor from entering the water outlet 5 through the water inlet 410 and the connecting pipe 7. During water dispensing, the pump delivers water into the second chamber 220, and then continues to deliver it, causing the hot water to rise through one end of the connecting pipe 7 to the top of the connecting pipe 7 and then flow through the other end of the connecting pipe 7 to the water outlet 5. The pump provides pressure, and the siphon effect is used to achieve continuous water dispensing.

[0048] Specifically, the length of the connecting pipe 7 towards the water tank 1 is greater than the length of the connecting pipe towards the water outlet 5, which also facilitates the recovery of water vapor.

[0049] The present invention also provides a method of use, applied to any of the sparkling water machines described above, comprising the following steps:

[0050] S1: The pump is used to deliver the water to be heated to the second chamber 220 through the water inlet pipe 111;

[0051] S2: When the water level in the first chamber 210 exceeds the water inlet 410, the water seals the water inlet 410, and the pump stops pumping.

[0052] S3: The heating element heats the water in the second chamber 220;

[0053] S4: After heating is complete, the hot water is pumped through the hot water pipe 4 and the connecting pipe 7 to the water outlet 5.

[0054] The principle of this invention is that the water tank 1 has a water-containing cavity 2, which is used to heat the water in the water-containing cavity 2. The water tank 1 is used to divide the water-containing cavity 2 by the partition 3 to form a first cavity 210 and a second cavity 220 that are interconnected. At the same time, the inlet end of the hot water pipe 4 is located in the first cavity 210, and the water in the second cavity 220 enters the first cavity 210 to seal the inlet end of the hot water pipe 4. In this way, when heating, water vapor will not enter the water outlet 5 through the hot water pipe 4, thus preventing water from dripping from the water outlet.

[0055] Instructions for use: 1. Use the pump to deliver the water to be heated to the second chamber 220 through the inlet pipe 111; 2. When the water level in the first chamber 210 exceeds the inlet hole 410, the water seals the inlet hole 410 and the pump stops delivering water; 3. The heating element heats the water in the second chamber 220; 4. After heating is completed, use the pump to deliver the hot water sequentially through the hot water pipe 4 and the connecting pipe 7 to the outlet 5.

[0056] Based on the above solutions, if various modifications or variations to the present invention do not depart from the spirit and scope of the present invention, and if such modifications and variations fall within the scope of the claims and equivalent technologies of the present invention, then the present invention also intends to include such modifications and variations.
