Description

Technical Field

[0001] This utility model belongs to the field of heating equipment, and specifically relates to an instantaneous heating element. Background Technology

[0002] As living standards improve, people's demands for quality of life are also increasing. Water heaters and water dispensers with instant heating functions are becoming more and more widely used, enabling people to obtain hot water in a very short time when they need it, which greatly facilitates their lives.

[0003] Instantaneous heating elements typically include an outer shell with an internal instantaneous heating chamber, a baffle inside the instantaneous heating chamber, and end caps covering both ends of the outer shell. However, the inlet and outlet of existing instantaneous heating elements are usually located on the end caps, which are fixed to the outer shell by welding or screws. The baffle is placed as a separate component inside the outer shell. This results in the disadvantage of complex assembly steps for instantaneous heating elements. Not only is it necessary to consider the alignment of the inlet and outlet on the end cap with the instantaneous heating chamber, but also to meet the high sealing requirements between the end cap and other components, leading to assembly difficulties and low assembly efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an instantaneous heating element to solve the problem of low assembly efficiency of instantaneous heating elements.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an instant heating element, comprising an outer shell with an internal instant heating cavity, a heating element for heating the liquid inside the instant heating cavity, and a flow-dispersing element for turbulent flow of the liquid inside the instant heating cavity. The flow-dispersing element includes a flow-dispersing portion disposed within the instant heating cavity and mounting portions disposed at both ends of the flow-dispersing portion. The two mounting portions are respectively provided with an inlet channel and an outlet channel. The mounting portions extend through the outer shell into the instant heating cavity, so that the instant heating cavity is connected to an external water system through the inlet channel and the outlet channel. This technical solution has the following technical effects:

[0006] This invention integrates the inlet channel for liquid inflow and the outlet channel for liquid outflow onto two mounting parts of the turbulence-disrupting component, making the inlet and outlet channels of the instantaneous heating element an integral structure with the turbulence-disrupting component. This simplifies the overall structure of the instantaneous heating element. When the turbulence-disrupting component, heating element, and outer shell are installed, the connection between the inlet and outlet channels and the instantaneous heating cavity is completed. There is no need to consider the alignment and connection between the instantaneous heating cavity and the inlet or outlet channels on the outer shell during assembly, which greatly reduces assembly difficulty and improves assembly efficiency.

[0007] In the heating body, the inlet flow channel and the outlet flow channel respectively pass through the mounting portions at two ends of the turbulence portion in the axial direction and extend to the outer side wall of the turbulence portion at the end portion to communicate with the heating cavity. By arranging the one end of the inlet flow channel and the outlet flow channel communicated with the heating cavity on the turbulence portion located entirely in the heating cavity, the end portion of the inlet flow channel and the outlet flow channel can be ensured to be completely aligned with the heating cavity after assembly, and the assembly difficulty is reduced.

[0008] In the heating body, the shell comprises an outer tube and end covers covering two ends of the outer tube, the end covers are provided with through holes for penetrating the mounting portions, the mounting portions are provided with locking members, and the mounting portions press the end covers against the end portions of the outer tube through the locking members. When the mounting portions are assembled with the end covers, the locking members abut against the ends of the end covers away from the outer tube in the axial direction to press the end covers against the end portions of the outer tube, and the locking between the two end covers and the outer tube is achieved, without the need of using screws or other fixing members to lock the end covers and the outer tube, the assembly difficulty between the end covers and the outer tube is reduced, the assembly efficiency is improved, and the production and processing cost is further reduced.

[0009] In the heating body, the locking member is a reverse buckle arranged on the outer side wall of the mounting portion, and the reverse buckle abuts against the end of the end cover away from the outer tube to press the end cover against the outer tube. The arrangement of the reverse buckle enables the locking between the mounting portion, the end cover and the outer tube to be completed only by inserting the mounting portion and the end cover into position, without the need of assembling the reverse buckle and the mounting portion, so that the assembly steps are simplified, the assembly difficulty is reduced, and the assembly efficiency is improved.

[0010] In the heating body, the end cover comprises a cover body provided with a through hole and a plurality of abutting protrusions, the plurality of abutting protrusions are fixed on the inner wall of the through hole and are distributed at intervals in the circumferential direction of the through hole, and the reverse buckle abuts against the abutting protrusions to press the end cover against the outer tube. The abutting protrusions have a certain elastic deformation amount, when the mounting portion is inserted into the through hole of the end cover, the reverse buckle pushes away the abutting protrusions to cause elastic deformation of the through hole of the end cover, so that the reverse buckle passes through, and after the reverse buckle passes through, the abutting protrusions are reset under the elastic action to abut against the reverse buckle, so that the limiting between the reverse buckle and the abutting protrusions is achieved, and the stable abutment between the end cover and the reverse buckle is ensured.

[0011] In the heating body, the locking member is a locking nut threadedly connected to the mounting portion, and the locking nut abuts against the end of the end cover away from the outer tube to press the end cover against the outer tube. The locking nut is threadedly connected to the mounting portion to limit the end cover in the axial direction, so that the end cover of different thicknesses can be pressed against the outer tube during installation and removal, and the application range is wider.

[0012] In the heating body, the turbulence part is a screw rod, and the heating part is a heating pipe, which is sleeved outside the screw rod and is sealingly connected with both ends of the screw rod to form a spiral heating cavity between the heating pipe and the screw rod. The heating part is arranged as a heating pipe, so that the tubular heating part can be sleeved outside the outer circumferential side of the screw rod and a spiral heating cavity is formed between the heating pipe and the screw rod. When water flows into the heating cavity through the liquid inlet flow channel, the water flows to the liquid outlet flow channel along the spiral heating cavity. The spiral heating cavity prolongs the flow time of the water in the heating cavity. The water can be heated by the heating pipe during the flow of the water, and the heating effect on the water is enhanced.

[0013] In the heating body, the end of the turbulence part and the heating pipe are sealingly connected through a sealing ring, and the screw rod is provided with a sealing groove surrounding the screw rod, and the sealing ring is embedded in the sealing groove. The screw rod and the heating pipe are sealingly connected by extruding the sealing ring, so that the sealing effect is good. Meanwhile, the sealing groove surrounding the screw rod is arranged on the screw rod to embed the sealing ring, so that the sealing ring can be axially limited, and the sealing ring can be stably sealed between the end of the screw rod and the heating pipe, and the sealing ring is prevented from moving along the axial direction of the screw rod.

[0014] In the heating body, the sealing ring comprises a first sealing part and a second sealing part connected with each other, the first sealing part is clamped between the screw rod and the inner wall of the heating pipe, and the second sealing part is clamped between the shell and the end face of the heating pipe. The sealing ring is arranged in a structure that the first sealing part and the second sealing part are combined, so that the sealing ring can not only fill the gap between the screw rod and the heating pipe to achieve sealing, but also fill the gap between the shell and the heating pipe to achieve sealing. The sealing area between the sealing ring and the heating pipe is increased. When the second sealing part is clamped by the shell and the heating pipe, the first sealing part clamped between the screw rod and the heating pipe can be axially limited, and the sealing ring is prevented from moving along the axial direction of the screw rod, and the sealing effect of the end of the heating cavity is further enhanced.

[0015] In the heating body, the heating body further comprises a temperature controller for adjusting the temperature of the heating pipe, and the temperature controller is arranged on the shell and abuts against the heating pipe.

[0035] Embodiment one:

[0036] A type of heat-generating body, such as Figures 1 to 5 As shown, the device includes a housing 100 with an internal instant heating chamber 211, a heating element 200, and a flow-dispersing element 300. The heating element 200 heats the liquid inside the instant heating chamber 211. The flow-dispersing element 300 includes a flow-dispersing portion 310 and mounting portions 320 located at both ends of the flow-dispersing portion 310. The flow-dispersing portion 310 is located inside the instant heating chamber 211 to turbulent the liquid inside the instant heating chamber 211, so that the liquid can fully contact the heating element 200, thereby improving the liquid flow within the instant heating chamber 211. Rapid heating is achieved by providing an inlet channel 321 and an outlet channel 322 on two mounting parts 320, which are respectively connected to both ends of the instant heating chamber 211. The mounting parts 320 extend through the outer shell 100 and out of the instant heating chamber 211, so that the instant heating chamber 211 is connected to the external water system through the inlet channel 321 and the outlet channel 322. The water from the external water system enters the instant heating chamber 211 through the inlet channel 321, and is then heated by the heating element 200 before flowing out of the instant heating chamber 211 through the outlet channel 322.

[0037] This invention simplifies the overall structure of the instantaneous heating element by setting the inlet channel 321 for liquid inflow and the outlet channel 322 for liquid outflow on the two mounting portions 320 of the baffle 300. This makes the inlet channel 321 and the outlet channel 322 of the instantaneous heating element an integral structure with the baffle 300. When the baffle 300, the heating element 200 and the outer shell 100 are installed, the connection between the inlet channel 321 and the outlet channel 322 and the instantaneous heating cavity 211 is completed. There is no need to consider the alignment and connection between the instantaneous heating cavity 211 and the inlet channel 321 or the outlet channel 322 on the outer shell 100 during assembly because the outer shell 100 has inlet channel 321 and outlet channel 322. This greatly reduces the assembly difficulty and improves the assembly efficiency.

[0038] like Figure 2 As shown, in this embodiment, the inlet channel 321 and the outlet channel 322 respectively penetrate the two mounting portions 320 at both ends of the turbulence portion 310 along the axial direction. The ends of the inlet channel 321 and the outlet channel 322 near the turbulence portion 310 extend axially to the turbulence portion 310 and finally emerge radially from the outer side walls at both ends of the turbulence portion 310 to communicate with the instant heating cavity 211. This reduces the manufacturing difficulty of the inlet channel 321 and the outlet channel 322 on the turbulence component 300. By setting the ends of the inlet channel 321 and the outlet channel 322 that communicate with the instant heating cavity 211 on the turbulence portion 310 that is entirely located in the instant heating cavity 211, it can be ensured that the ends of the inlet channel 321 and the outlet channel 322 are completely aligned with the instant heating cavity 211 when the assembly is completed, thus reducing the assembly difficulty.

[0039] In the embodiment, the shell 100 comprises an outer tube 110 with openings at two ends and end covers 120 covering the two ends of the outer tube 110, the end covers 120 are provided with through holes 123, the mounting portion 320 passes through the through holes 123 of the end covers 120 from the shell 100, the mounting portion 320 is provided with locking members, when the mounting portion 320 is assembled with the end covers 120, as shown in Figure 1 , the locking members abut against the side of the end covers 120 axially away from the outer tube 110 to press the end covers 120 against the end of the outer tube 110, and the locking between the two end covers 120 and the outer tube 110 is realized, without using screws or other fixing members to lock the end covers 120 and the outer tube 110, the assembly difficulty between the end covers 120 and the outer tube 110 is reduced, the assembly efficiency is improved, and the production and processing cost is further reduced.

[0040] As shown in Figure 5 , preferably, the locking members are a plurality of reverse buckles 323 provided on the outer sidewall of the mounting portion 320, during assembly, the mounting portion 320 passes through the through holes 123, in the process, the through holes 123 of the end covers 120 are deformed so that the reverse buckles 323 pass through the through holes 123 together with the mounting portion 320, when the reverse buckles 323 completely pass through the through holes 123, the end covers 120 are elastically reset, and the plurality of reverse buckles 323 abut against the end covers 120 on the circumferential side of the through holes 123 to press the end covers 120 against the end of the outer tube 110. The reverse buckles 323 are provided, so that during assembly, only the mounting portion 320 and the end covers 120 need to be inserted in place to complete the locking of the mounting portion 320, the end covers 120 and the outer tube 110, without assembling the reverse buckles 323 and the mounting portion 320, the assembly steps are simplified, the assembly difficulty is reduced, and the assembly efficiency is improved. As shown in Figure 4 , the end cover 120 in the embodiment comprises a cover body 121 provided with a through hole 123 and a plurality of abutting protrusions 122, the plurality of abutting protrusions 122 are fixed on the inner wall of the through hole 123 and are distributed at intervals along the circumference of the through hole 123, the abutting protrusions 122 have a certain elastic deformation amount, when the mounting portion 320 is inserted into the through hole 123 of the end cover 120, the reverse buckles 323 push away the abutting protrusions 122, the through hole 123 of the end cover 120 is elastically deformed so that the reverse buckles 323 pass through, after the reverse buckles 323 pass through, the abutting protrusions 122 are reset under the action of elasticity to abut against the reverse buckles 323, the limiting between the abutting protrusions 122 and the reverse buckles 323 is realized, and the stable abutment between the end cover 120 and the reverse buckles 323 is ensured. Of course, it can be understood that the through hole can also be provided with a structure that cannot be deformed, one end of the elastic sheet is connected to the inner wall of the through hole to form a reverse buckle with elasticity, when the reverse buckle passes through the through hole, it is elastically deformed towards the mounting portion under the extrusion of the through hole to pass through the through hole, after the reverse buckle completely passes through the through hole, the reverse buckle is reset under the action of elasticity without being extruded by the through hole, and the end of the reverse buckle that can be freely deformed abuts against the end cover 120 to realize the locking between the end cover 120 and the outer tube 110.

[0041] like Figure 2 As shown, in this embodiment, the turbulence-disrupting part 310 is a screw 311, and the heating element 200 is a hollow heating tube 210. The heating tube 210 is sleeved on the outside of the screw 311, and both ends of the heating tube 210 are sealed to both ends of the screw 311 to form a spiral instant heating cavity 211 between the heating tube 210 and the screw 311. By setting the heating element 200 as a heating tube 210, the tubular heating element 200 can be sleeved on the outer periphery of the screw 311, forming a spiral instant heating cavity 211 between them. When water flows into the instant heating cavity 211 from the inlet channel 321, it will flow along the spiral instant heating cavity 211 to the outlet channel 322. The spiral instant heating cavity 211 prolongs the flow time of the water in the instant heating cavity 211. During the water flow process, the water can always be heated by the heating tube 210, enhancing the heating effect of the water flow.

[0042] A sealing ring 400 is provided between the end of the turbulence section 310 and the heating tube 210. A sealing groove 312 is provided on the screw 311, surrounding the screw 311. The sealing ring 400 is embedded in the sealing groove 312 and abuts against the inner wall of the heating tube 210, so that the end of the screw 311 and the heating tube 210 are sealed together by the sealing ring 400. The sealing connection between the screw 311 and the heating tube 210 is achieved by compressing the sealing ring 400, which has a good sealing effect. At the same time, the sealing groove 312 surrounding the screw 311 to embed the sealing ring 400 can limit the sealing ring 400 axially, ensuring that the sealing ring 400 can be stably sealed between the end of the screw 311 and the heating tube 210, and preventing the sealing ring 400 from moving axially along the screw 311.

[0043] Preferably, such as Figure 3As shown, the sealing ring 400 comprises a first sealing part 410 and a second sealing part 420 arranged integrally, the first sealing part 410 extends along the axial direction of the screw rod 311 and is clamped between the screw rod 311 and the inner wall of the heating pipe 210 to seal between the screw rod 311 and the heating pipe 210, and the second sealing part 420 extends along the radial direction of the screw rod 311 and is clamped between the end cover 120 on the side of the through hole 123 and the end face of the heating pipe 210 to seal between the end cover 120 and the heating pipe 210. By arranging the sealing ring 400 in the structure that the first sealing part 410 and the second sealing part 420 are combined, the sealing ring 400 can not only fill the gap between the screw rod 311 and the heating pipe 210 to achieve sealing, but also fill the gap between the shell 100 and the heating pipe 210 to achieve sealing, increase the sealing area between the sealing ring 400 and the heating pipe 210, and when the second sealing part 420 is clamped by the shell 100 and the heating pipe 210, the first sealing part 410 clamped between the screw rod 311 and the heating pipe 210 can be limited in the axial direction, avoiding the movement of the sealing ring 400 along the axial direction of the screw rod 311, and further enhancing the sealing effect of the end part of the instant heating cavity 211.

[0044] The instant heating body in the embodiment further comprises a temperature controller 500, the temperature controller 500 is arranged on the shell 100 and abuts against the outer side wall of the heating pipe 210, and can adjust the temperature of the heating pipe 210 to regulate the temperature of the water flow passing through the instant heating cavity 211, so that the water flow with the set temperature can be output according to the needs of the user, and the user experience is good.
