[0002] The steam generator is a key mechanical component of a dishwasher, heating liquid to generate steam that is then transported to the dishwasher's interior to sterilize dishes. A steam generator typically comprises a heating element and a liquid conduit. However, the liquid conduit in existing steam generators is typically positioned around the heating element, resulting in a relatively large length and radial dimensions. This results in a bulky steam generator, which takes up excessive space within the dishwasher. Utility Model Content

[0003] Based on this, it is necessary to provide a steam generating device and a dishwasher to address the problem that the liquid conduit of the existing steam generating device is generally arranged around the heating element, which leads to a larger volume of the entire steam generating device.

[0004] A steam generating device comprises: a shell assembly; a liquid guiding assembly, wherein the liquid guiding assembly is arranged on the shell assembly, the liquid guiding assembly is provided with a liquid inlet and a steam outlet, the liquid guiding assembly is provided with a liquid guiding channel, the liquid inlet, the liquid guiding channel and the steam outlet are connected in sequence; a heating assembly, wherein the heating assembly is arranged on the shell assembly, the horizontal plane where the heating assembly is located is parallel to the horizontal plane where the liquid guiding assembly is located, or the angle between the horizontal plane where the heating assembly is located and the horizontal plane where the liquid guiding assembly is located is greater than 0° and less than or equal to 5°, and the heat generated by the heating assembly can be conducted to the liquid guiding assembly.

[0005] The first aspect of the present application discloses a steam generating device, in which the heat generated by the heating component can be conducted to the liquid guiding component, so that the pure water can be heated to the boiling point of the pure water in the liquid guiding channel and quickly form steam, and the steam is output from the steam outlet for disinfection. By making the horizontal plane where the heating component is located parallel to the horizontal plane where the liquid guiding component is located, the space required for the heating component and the liquid guiding component is less, and the structure is more compact, so that the steam generating device is more miniaturized and suitable for the limited assembly space of the dishwasher. Moreover, the heat conduction range of the parallel-arranged heating component and the liquid guiding component is increased, which can ensure the efficiency of heat transfer and realize rapid heating of the liquid in the liquid guiding component. This design enables the liquid guiding component to be heated evenly, avoiding the phenomenon of local overheating or insufficient heating. The layout of the steam generating device of the present application is more reasonable, convenient for subsequent disassembly and maintenance, and worthy of promotion and use.

[0006] In one embodiment, the liquid-conducting assembly and the heating assembly are located on either side of the housing assembly. By locating the heat-conducting assembly and the heating assembly on either side of the housing assembly, heat generated by the heating assembly on one side of the housing assembly can be transferred through the housing assembly to the liquid-conducting assembly on the other side of the housing assembly, resulting in improved heat conduction. This design ensures more uniform heating of the liquid-conducting assembly and improves steam generation efficiency.

[0007] In one embodiment, the liquid-guiding component is wavy or serpentine. By folding the liquid-guiding component into a wavy or serpentine shape, the overall length of the liquid-guiding component is reduced, resulting in a smaller overall volume and less space required. Furthermore, a sufficiently long liquid delivery path within the liquid-guiding component is ensured, allowing the liquid to be more fully heated within the liquid-guiding component.

[0008] In one embodiment, the projection of the heating assembly on the housing assembly is staggered with the projection of the liquid-guiding assembly on the housing assembly. By staggering the projection of the heating assembly on the housing assembly and the projection of the liquid-guiding assembly on the housing assembly, the layout of the heating assembly and the liquid-guiding assembly is rationalized, so that the heating assembly and the liquid-guiding assembly are respectively located on different sides of the housing assembly, thereby making the assembly of the heating assembly and the liquid-guiding assembly simpler and more convenient, and subsequent maintenance is also simpler.

[0009] In one embodiment, the heating assembly is wavy or serpentine. The wavy or serpentine shape of the heating assembly increases the surface area of the heating assembly and improves the heat exchange efficiency between the heating assembly and the liquid guide assembly. Furthermore, heat is evenly distributed across the heating assembly, preventing localized overheating of the heating assembly and improving the stability and safety of the heating process. Preferably, the total length of the straightened heating assembly is approximately 350 mm, capable of maintaining a power of 1700 W, thereby achieving high heating efficiency.

[0010] In one embodiment, the heating assembly includes a heating tube, a first power connection end, and a second power connection end. The heating tube is disposed on the housing assembly, and the first power connection end and the second power connection end are both disposed on the heating tube and located at opposite ends of the heating tube, respectively. The first power connection end and the second power connection end are used to connect to an external power source. The first power connection end and the second power connection end are used to connect to the external power source, so that the external power source provides continuous and stable electrical energy to the heating assembly, allowing the heating assembly to continuously generate heat and conduct it to the liquid guide assembly.

[0011] In one embodiment, the liquid guide assembly includes a liquid guide pipe, a liquid inlet joint, and a steam outlet joint. The liquid guide pipe is arranged on the shell assembly and located in the installation cavity. The liquid guide pipe is wavy or winding. The liquid guide pipe is provided with the liquid guide channel. The liquid inlet joint and the steam outlet joint are both arranged on the liquid guide pipe. The liquid inlet joint is provided with the liquid inlet, and the steam outlet joint is provided with the steam outlet. The arrangement of the liquid inlet joint and the steam outlet joint makes the connection with the external structure faster and more secure. It can also withstand a certain hydraulic pressure to ensure that liquid and steam can pass smoothly, and has good practicality.

[0012] In one embodiment, the liquid-conducting tube comprises a straight tube section and an arc tube section. Multiple straight tube sections and multiple arc tube sections are provided, alternating between the straight tube sections and the arc tube sections to form the liquid-conducting channel. This alternating arrangement of multiple arc tube sections and straight tube sections makes the liquid-conducting tube section more compact, thereby optimizing the liquid flow path and reducing resistance to liquid flow. This also enhances structural strength and improves product reliability.

[0013] In one embodiment, a first adapter groove and a second adapter groove are respectively provided on both sides of the shell assembly, and the heating component and the liquid guide component are both arranged on the shell assembly, the heating component is located in the first adapter groove, and the heating component is adapted to the first adapter groove, and the liquid guide component is located in the second adapter groove, and the liquid guide component is adapted to the second adapter groove. By adapting the liquid guide component to the first adapter groove and the liquid guide component to the second adapter groove, the space occupied by the heating component and the liquid guide component is further reduced, so that the overall structure is more compact. Moreover, the heat generated by the heating component on one side of the shell assembly can be transferred to the liquid guide component on the other side of the shell assembly through the shell assembly, and the heat conduction effect is good.

[0014] In addition to the features of the above embodiment, this embodiment further provides that the heating assembly, the liquid guide assembly, and the housing assembly are integrally formed. During product manufacturing, the heating assembly and the liquid guide assembly are placed within a mold cavity, and aluminum die-casting is used to form the housing assembly surrounding the heating assembly and the liquid guide assembly. This can simplify the product production process and improve production efficiency.

[0015] In one embodiment, the device further includes a first shell and a second shell, wherein the first shell and the second shell are connected, and the first shell and the second shell enclose an installation space, and the shell assembly is arranged on the first shell and / or the second shell and is located in the installation space. The split arrangement of the first shell and the second shell facilitates installation and disassembly, thereby simplifying subsequent maintenance. In addition, the arrangement of the first shell and the second shell also has the effect of protecting the internal structure and heat preservation. Through the reasonable arrangement of the first shell, the second shell and the shell assembly, the space utilization effect is improved, unnecessary space occupation is reduced, and the overall structure is more miniaturized.

[0016] In one embodiment, the liquid guiding component is made of stainless steel. By making the liquid guiding component of stainless steel, the liquid guiding component has good thermal conductivity, good corrosion resistance and increased durability.

[0017] In one embodiment, the housing assembly is made of aluminum material. By making the housing assembly of aluminum material, the housing assembly is easy to process and convenient to manufacture.

[0018] In one embodiment, the invention further includes a thermostat and a temperature detector, both of which are disposed on the housing assembly. The thermostat and the heating assembly are located on the same side of the housing assembly, and the thermostat is electrically connected to the temperature detector and the heating assembly, respectively. By electrically connecting the thermostat to the temperature detector and the heating assembly, respectively, precise temperature control can be achieved, allowing the liquid to be continuously converted into water vapor. By locating the thermostat and the heating assembly on the same side of the housing assembly, the mold's sliding mechanism can reduce mold costs for single-side core pulling.

[0019] In one embodiment, the liquid guide assembly offsets the heating assembly. This offset reduces the intermediate links in heat transfer, improves heat transfer efficiency, reduces liquid heating time, and makes the product more compact.

[0020] In one embodiment, the projection of the heating tube on the housing assembly overlaps with the projection of the liquid guide assembly on the housing assembly. By aligning the projections of the heating tube on the housing assembly with the projections of the liquid guide assembly on the housing assembly, the heating tube and the housing assembly offset each other, thereby improving the heat transfer efficiency of the heating tube, reducing energy waste and improving energy utilization. Furthermore, the heating tube can be protected from localized overheating or overcooling, reducing the risk of damage caused by persistently high local temperatures.

[0021] A dishwasher comprises: a dishwasher body; and the above-mentioned steam generating device, wherein the steam generating device is arranged on the dishwasher body and is used to generate steam and transport the steam into the interior of the dishwasher body.

[0022] A second aspect of the present application discloses a dishwasher that uses a steam generator to generate high-temperature steam that is delivered to the interior of the dishwasher body, thereby sterilizing tableware placed within the dishwasher body and killing bacteria and viruses on the tableware.

Because the horizontal plane where the heating component 3 is located is parallel to the horizontal plane where the liquid guiding component 2 is located, the space required for the heating component 3 and the liquid guiding component 2 is less, and the structure is more compact, so that the steam generating device is more miniaturized and suitable for the assembly space with limited space of the dishwasher. Moreover, the heat conduction range of the parallel-arranged heating component 3 and the liquid guiding component 2 is increased, which can ensure the efficiency of heat transfer and realize rapid heating of the liquid in the liquid guiding component 2. This design enables the liquid guiding component 2 to be heated evenly, avoiding the phenomenon of local overheating or insufficient heating.
