Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to an electric heating steam product for household appliances. Background Technology

[0002] Electric steam heating products play a crucial role in household appliances such as steam ovens, steam cookers, and range hoods. However, current electric steam heating products on the market suffer from the following problems: 1. Due to their large overall size, installation and use are easily restricted, especially with unreasonable design of the inlet and outlet mechanisms, leading to increased manufacturing difficulty and inconvenient installation and use; 2. Inadequate insulation results in significant energy loss. Therefore, it is essential to improve existing electric steam heating products to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide an electrically heated steam product. This invention adopts a bottom inlet and outlet design, which reduces manufacturing difficulty, increases production efficiency, and reduces production costs. At the same time, it improves heating efficiency and reduces energy consumption by adding an insulation structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electrically heated steam product, comprising a shell, an electric heating module disposed within the shell for heating a liquid, and a fluid system for controlling the entry and exit of fluid from the electric heating module. The electric heating module includes an electric heating body, which has a chamber inside. An electric heating tube is disposed on the electric heating body. The electric heating body is provided with an entry mechanism and an exit mechanism connecting the inside and outside of the chamber. The fluid system is disposed at the bottom of the electric heating module and includes a pump, an inlet pipe, a connecting pipe, and an exit pipe. The pump is installed inside the shell. One end of the connecting pipe is connected to the outlet of the pump, and the other end of the connecting pipe is connected to the outer end of the inlet mechanism. The inlet pipe is connected to the inlet of the pump, and the exit pipe is connected to the outer end of the exit mechanism. Both the outer ends of the inlet pipe and the exit pipe extend from the bottom of the shell.

[0005] By adopting the above technical solution, the electric heating module is innovatively structurally designed with a bottom entry and exit design, which reduces manufacturing difficulty, increases production efficiency, and thus reduces production costs.

[0006] The present invention is further configured such that the electric heating body inlet mechanism and outlet mechanism are located at the bottom of the electric heating body, and the fluid system is located below the electric heating module.

[0007] By adopting the above technical solution and using a bottom-entry, centrally positioned design, the incoming fluid is forced out under pressure, strikes the inner surface of the heating element, and then scatters around the cavity to form water droplets. This increases the contact with the inner surface of the heating element, making it easier to be heated and quickly atomize to generate steam.

[0008] The present invention is further configured such that a pump fixing bracket is provided inside the outer shell, and the pump is mounted on the pump fixing bracket.

[0009] By adopting the above technical solution, the pump can be fixedly installed.

[0010] The present invention is further provided with a heat preservation device made of heat preservation material, wherein the heat preservation device covers the electric heating body inside, and the outer wall of the electric heating body is provided with an assembly mechanism for fixing the heat preservation device.

[0011] By adopting the above technical solutions and adding insulation devices, heating efficiency can be improved and energy consumption reduced.

[0012] The present invention is further configured such that the heat preservation device includes a heat preservation upper cover and a heat preservation lower cover, both of which are hollow and open at one end. The heat preservation upper cover and the heat preservation lower cover are connected together and form a heat preservation cavity inside. The electric heating body is disposed inside the heat preservation cavity.

[0013] By adopting the above technical solution, and using the method of splicing the upper and lower insulation covers around the outer periphery of the electric heating body, the openings of the insulation device are minimized to avoid heat radiation diffusion.

[0014] The present invention is further configured such that an annular positioning protrusion is provided on the end face of the heat-insulating upper cover, and a positioning groove adapted to the positioning protrusion is provided on the end face of the heat-insulating lower cover.

[0015] By adopting the above technical solution, it is not only beneficial to position and install the upper and lower insulation covers, but also to make the connection structure between the two more stable.

[0016] The present invention is further configured such that an electric heating body fixing bracket is connected to the pump fixing bracket, and the electric heating body is connected to the electric heating body fixing bracket by fasteners, thereby separating the electric heating body from the inner wall of the outer shell.

[0017] By adopting the above technical solution, while using the electric heating body fixing bracket to install from the bottom, the outer shell is also separated by the pump fixing bracket, which further reduces the heat transfer from the solid, thereby effectively reducing temperature transfer and reducing the temperature rise of the outer shell.

[0018] The present invention is further configured such that the mechanism for direct installation and fixation with the electric heating body is housed within the outer casing.

[0019] By adopting the above technical solution, the temperature of metal parts that are in direct contact with the heating element is prevented from being exposed outside the casing, thus avoiding the temperature rise from failing to meet the standard. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: As attached Figure 1 and attached Figure 2The electric heating steam product shown (the bottom of the actual product is shown to the right in the attached figure) includes a shell 1, an electric heating module 2 for heating liquid disposed within the shell 1, and a fluid system 3 for controlling the entry and exit of fluid from the electric heating module 2. The shell 1 can be designed as a split structure to facilitate the installation of internal devices. The electric heating module 2 includes an electric heating body 21, which has a chamber 22. An electric heating tube 23 is disposed on the electric heating body 21, and the electric heating tube 23 can be cast onto the electric heating body 21. An entry mechanism communicating between the inside and outside of the chamber 22 of the electric heating body 21 is provided on the electric heating body 21. The electric heating module 24 and the exhaust mechanism 25 are integrated into the heating body 21. The inlet mechanism 24 is the water inlet pipe, and the exhaust mechanism 25 is the air outlet pipe. In this embodiment, the water inlet pipe and the air outlet pipe are integrated into the heating body 21. The fluid system 3 includes a pump 31, an inlet pipe 32, a connecting pipe 33, and an exhaust pipe 34. The pump 31 is installed inside the housing 1. One end of the connecting pipe 33 is connected to the outlet of the pump 31, and the other end of the connecting pipe 33 is connected to the outer end of the inlet mechanism 24. The inlet pipe 32 is connected to the inlet of the pump 31, and the exhaust pipe 34 is connected to the outer end of the exhaust mechanism 25. Both the inlet pipe 32 and the exhaust pipe 34 extend from the bottom of the housing 1. This design innovatively designs the electric heating module 2 with a bottom inlet and exhaust design, thereby reducing manufacturing difficulty, increasing production efficiency, and reducing production costs.

[0029] As attached Figure 1 As shown, the electric heating body 21 has an inlet mechanism 24 and an outlet mechanism 25 located at the bottom of the electric heating body 21, and the fluid system 3 is located below the electric heating module 2. It adopts a bottom-inlet, center-positioned design. The incoming fluid is forced out under pressure, impacting the inner surface of the electric heating body 21 and then scattering around the cavity to form water droplets. This increases the contact with the inner surface of the electric heating body 21, making it easier to heat up and quickly atomize to generate steam.

[0030] As attached Figure 1 As shown, the housing 1 is equipped with a pump mounting bracket 26. The mounting bracket can be connected to the bottom of the housing 1 with screws or by welding. The pump 31 can be installed on the pump mounting bracket 26 by bolts. This design allows for convenient installation of the pump 31.

[0031] As attached Figure 1 and attached Figure 2As shown, the electrically heated steam product also includes a heat-insulating device 4 made of heat-insulating material. The heat-insulating material can be a high-temperature resistant and heat-insulating material such as stainless steel, rock wool, or polyurethane foam. The heat-insulating device 4 encloses the electric heating body 21, and an assembly mechanism 27 for fixing the heat-insulating device 4 is provided on the outer wall of the electric heating body 21. In this embodiment, the assembly mechanism 27 is a positioning post integrally set on the outside of the electric heating body 21, and the positioning post 21 is connected to the heat-insulating device 4 by means of screws or other fasteners. Adding the heat-insulating device 4 can improve heating efficiency and reduce energy consumption.

[0032] In addition, the insulation device 4 needs to have an opening for the entry mechanism 24 and the discharge mechanism 25 to pass through.

[0033] As attached Figure 1 As shown, the heat preservation device 4 includes a hollow upper cover 41 and a lower cover 42, both open at one end. The upper cover 41 and the lower cover 42 are connected and form a heat preservation cavity 43 inside, and the electric heating body 21 is disposed inside the heat preservation cavity 43. By using the method of splicing the upper cover 41 and the lower cover 42 around the electric heating body 21, the openings of the heat preservation device 4 are minimized, thus avoiding heat radiation diffusion.

[0034] As attached Figure 1 As shown, the end face of the heat-insulating upper cover 41 is provided with an annular positioning protrusion 44, and the end face of the heat-insulating lower cover 42 is provided with a positioning groove 45 that matches the positioning protrusion 44. The connection between the heat-insulating upper cover 41 and the heat-insulating lower cover 42 can be achieved by the interference fit between the positioning protrusion 44 and the positioning groove 45. This design not only facilitates the positioning and installation of the heat-insulating upper cover 41 and the heat-insulating lower cover 42, but also makes the connection structure between the two more stable.

[0035] As attached Figure 1 As shown, the pump mounting bracket 26 is connected to the heating element mounting bracket 26, and the two can be bolted together. The heating element 21 is connected to the heating element mounting bracket 26 by fasteners, which can be screws or bolts, thus separating the heating element 21 from the inner wall of the outer casing 1. This design integrates the mechanism for directly mounting the heating element 21 within the outer casing 1. While the heating element mounting bracket 26 is installed from the bottom, the pump mounting bracket 26 further isolates the outer casing 1, reducing heat transfer through the solid and effectively lowering temperature rise. Furthermore, by integrating the mechanism for directly mounting the heating element 21 within the outer casing 1, the design prevents the temperature of metal parts in direct contact with the heating element 21 from being exposed outside the outer casing 1, thus avoiding substandard temperature rise.
