[0002] Currently, dishwashers on the market generally use high-temperature steam to clean oil stains on dishes. This involves heating water with a steam generator to produce high-temperature, high-pressure steam, which is then used to clean and sterilize the dishes inside the dishwasher cavity.

[0003] However, existing dishwashers, due to their large cavity space, often struggle to clean grease off dishes when the steam concentration is low during the steam heating process. Furthermore, the heating plate requires the water in the storage tank to be heated to a certain temperature before steam can be generated. The large amount of water on the surface of the heating plate results in low heating efficiency, long heating time, and slow steam output, making it difficult to meet the dishwasher's demand for high-temperature steam and resulting in poor cleaning effect on greasy dishes that are difficult to clean. Utility Model Content

[0029] Reference Figure 1-5 This invention describes a dishwasher that generates steam quickly according to an embodiment of the present invention.

[0030] In one embodiment, such as Figure 1-5As shown, a dishwasher that generates steam quickly includes a body 2 and a steam generator 1, which supplies steam to the cavity of the body 2.

[0031] The steam generating device 1 includes a heating water tank 11, a heating plate 12, and a steam support 13. The bottom of the heating water tank 11 is provided with an opening, and the heating plate 12 is located below the opening. The steam support 13 is installed on the opening, and the bottom surface of the steam support 13 does not contact the heating plate 12.

[0032] The steam support 13 has a recessed cavity 131 with an upper opening in the middle, and a side cavity 132 with a lower opening around the recessed cavity 131. The interior of the recessed cavity 131 is not connected to the heating water tank 11, and the upper end of the side cavity 132 is connected to at least one first steam outlet 133.

[0033] The steam support 13 may have a shape that matches the opening, such as a circle, rectangle, polygon or other shape. Correspondingly, the cavity 131 may also be a circle, rectangle or other shape. The side cavity 132 is arranged around the cavity 131 and has an opening at the lower end. When the cavity 131 is a circular cavity, the side cavity 132 may be an annular side cavity. Preferably, the steam support 13 is an integrally formed structure.

[0034] Specifically, when the steam support 13 is installed into the steam generator 1, the water is only located between the bottom surface of the concave cavity 131 and the upper surface of the heating plate 12, as well as in the side cavity 132, thereby maximizing the drainage of water in the middle area above the heating plate 12, significantly reducing the amount of water being heated, and thus improving the steam generation efficiency.

[0035] The dishwasher with rapid steam generation provided in the above embodiment can reduce the water capacity above the heating plate 12 by installing a steam bracket 13, thereby significantly reducing the amount of water to be heated and increasing the heating efficiency. This shortens the steam generation time of the steam generator and quickly produces a large amount of steam, thereby rapidly increasing the steam temperature and concentration in the dishwasher cavity. This enhances the disinfection effect and improves the disinfection efficiency, improving the dishwasher's ability to remove grease and effectively cleaning and disinfecting oily tableware that is difficult to clean. At the same time, the steam bracket 13 does not directly contact the heating plate 12, which can prevent the steam bracket 13 from being melted by the high temperature of the heating plate 12 during operation and ensure structural stability.

[0036] In this embodiment, the bottom surface of the cavity 131 is provided with an upward-facing hollow protrusion 134, the lower end of the hollow protrusion 134 is open, and the top of the hollow protrusion 134 is provided with at least one second steam outlet 135, which serves to exhaust steam and dissipate heat.

[0037] The hollow protrusions 134 can be one or more; the hollow protrusions 134 can be hollow cylindrical, conical, or other shapes.

[0038] In specific implementation, when the bottom surface of the concave cavity 131 is provided with only one hollow protrusion 134, the hollow protrusion 134 can be provided at the center of the bottom surface of the concave cavity 131, so that steam flows out from the center of the steam support 13, ensuring that the steam output is evenly distributed.

[0039] In this embodiment, at least one second steam outlet 135 is evenly distributed on the top surface of the hollow protrusion 134, and the top edge of the hollow protrusion 134 is provided with an upward flange 136. The flange 136 is arranged around the multiple second steam outlets 135 to facilitate the concentrated upward movement of steam.

[0040] The above embodiment allows the steam support 13 to emit steam simultaneously from all sides and above through the first steam outlet 133 and the second steam outlet 135, enabling the steam to fill the cavity of the dishwasher in a shorter time and achieve higher steam temperature and steam concentration.

[0041] In this embodiment, the lower part of the outer wall of the steam bracket 13 is provided with a mounting limiting part 137 that engages with the edge of the opening. The mounting limiting part 137 may be a flange that engages with the upper edge of the opening. In one embodiment, the edge of the opening is symmetrically provided with two inwardly pointing limiting protrusions. The maximum outer diameter of the mounting limiting part 137 is the same as the inner diameter of the opening. The mounting limiting part 137 includes a locking groove, and two limiting recesses are symmetrically provided on both sides of the locking groove. The steam bracket 13 is placed into the opening by aligning the limiting recesses with the limiting protrusions on the edge of the opening, and then the steam bracket 13 is rotated so that the limiting protrusions on the opening slide into the locking groove, thereby detachably mounting the steam bracket 13 onto the opening.

[0042] In this embodiment, the upper end of the side cavity 132 is connected to at least two first steam outlets 133 facing outward.

[0043] At least two first steam outlets 133 may be symmetrically arranged on the top of the steam support 13 and communicate with the upper end of the side cavity 132; each first steam outlet 133 may include multiple steam outlets arranged in parallel.

[0044] It should be noted that this embodiment is only one implementation method of this application. In actual implementation, the first steam outlet 133 may also be arranged facing inward or upward, depending on the design requirements.

[0045] In this embodiment, a connecting part is provided at the edge of the opening, the heating plate 12 is fixedly connected to the connecting part, and the heating plate 12 and the connecting part are sealed by a sealing ring 121 to ensure sealing performance.

[0046] In this embodiment, the steam generator 1 is located outside the cavity; the steam generator 1 is connected to the cavity through a gas guide pipe to introduce steam into the cavity, and the heating water tank 11 is connected to a water supply component. In order to avoid mixing water, the water supply component can be used to replenish water to the steam generator 1 separately.

[0047] In practice, when the steam generator 1 is located outside the dishwasher cavity, the steam generator 1 can use a separate water supply and is easy to disassemble and clean.

[0048] In this embodiment, the steam generator 1 is located inside the cavity; the body 2 is equipped with a water tank 14 and a water pump 15. The water tank 14 is connected to the heating water tank 11 through the water pump 15 and is used to supply water to the heating water tank 11.

[0049] Specifically, water from water tank 14 enters heating water tank 11 through water pump 15. When the preset water level is reached above heating plate 12, heating plate 12 starts to heat up, heating the water between steam bracket 13 and heating plate 12. The generated steam enters the cavity of dishwasher through the first steam outlet 133 and the second steam outlet 135 on steam bracket 13 to achieve steam cleaning and disinfection.

[0050] Throughout the process, the amount of water that needs to be heated is greatly reduced due to the steam support 13, thus shortening the heating time and increasing the steam output efficiency.

[0051] In this embodiment, the cavity is equipped with two sets of spray arm assemblies 3, located at the upper and lower parts of the cavity respectively. Each spray arm assembly 3 includes a spray arm cover 31, a spray arm seat 32, a spray arm tube 33, and a spray arm tube seat 34. The spray arm cover 31 covers the spray arm seat 32 and has multiple water spray holes. The spray arm seat 32 is connected to one end of the spray arm tube 33, and the other end of the spray arm tube 33 is connected to the spray arm tube seat 34. The spray arm tube seat 34 is connected to a water supply pipe. In practice, the spray arm assembly 3 is used to spray and clean tableware.

[0052] The front of the main body 2 has a door 4 for sealing the cavity, and a detergent assembly 5 is provided on the door 4. The detergent assembly 5 is used to provide detergent for the dishwashing process. The front of the door 4 has a glass panel 41.

[0053] In this embodiment, a filter assembly 6 is also provided inside the body 2. The filter assembly 6 is located at the bottom of the cavity and is used to filter the wastewater generated from washing tableware. The filter assembly 6 includes a filter 61, a filter screen 62, and a filter screen box 63 arranged sequentially from top to bottom. The filter screen 62 has a through hole in the middle, and the bottom of the filter 61 passes through the through hole and is installed in the filter screen box 63.

[0054] In each of the above embodiments, the body 2 may include a housing 21, a metal cavity 22 and a base bracket 23. The metal cavity 22 is disposed inside the housing 21 and constitutes the cavity of the dishwasher. The base bracket 23 is disposed inside the housing 21 and located below the metal cavity 22. The bottom plate of the metal cavity 22 is provided with grooves for accommodating the water tank 14 and the filter assembly 6 respectively, and is also provided with a heating water tank 11.
