DETAILED DESCRIPTION

[0041] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0042] The present invention provides a dishwasher, comprising a housing and a washing space located within the housing. The washing space is provided with a washing water passage 2 and a washing basket 1 for holding tableware. The washing basket 1 includes a bottle washing area 3. One or more supporting and fixing components are provided on the washing basket 1 in the bottle washing area 3. The washing water passage 2 is provided with a spray port 4 at each supporting and fixing component.

[0043] like Figure 1 As shown, a dishwasher has a corresponding water channel (not shown in the figure) provided at the bottom of the inner tank, and a washing water channel 2 for spraying washing water to the dishes to be washed is connected to the water channel. A washing basket 1 is provided on the upper part of the washing water channel 2. The basket 1 is a frame structure for placing tableware. It may include a bottle washing area 3 for mainly cleaning slender windows such as bottles and cups, or in actual application, the washing basket 1 only places tableware such as bottles and cups, especially baby products: feeding bottles, nipples, feeding bottle caps, chewing gum and other tableware, which are not limited here. A plurality of supporting and fixing components are provided on the washing basket 1 for supporting or fixing the aforementioned tableware, especially baby products. The supporting and fixing components are used to fix the tableware, and point contact is achieved between the supporting and fixing components and the tableware. By fixing the supporting and fixing components with the tableware in point contact, the problem of poor cleaning effect at the contact position is solved, and dead corners in washing are eliminated.

[0044] like Figure 2 As shown, the supporting and fixing components include but are not limited to a bottle support structure 6, a nipple fixing structure 7, a nipple fixing mounting seat 9, and a support 8 for placing small tableware. In this embodiment, the supporting and fixing components include four bottle support structures 6 and four nipple fixing structures 7, which are used to wash four sets of baby bottles at the same time.

[0045] like Figure 3 As shown, each bottle body support structure 6 includes a support column 61, and at least two support columns 61. In this embodiment, there are four support columns 61. In order to save costs and reasonably design space, there are common support columns 61 in the four bottle body support structures 6. The number of support columns 61 to be used can be determined according to the size of the bottle.

[0046] There is a fixing member at the top of the support column 61, which can achieve point contact with the side wall of the feeding bottle. For example, in this embodiment, a rubber fixing ball 62 is set on the top of the support column 61. The rubber fixing ball 62 is used to contact the outer wall of the feeding bottle and fix the feeding bottle. The bottom of the support column 61 is fixed to the main body 1. The bottle body support structure 6 is provided with four support columns 61 to support the outside of the feeding bottle, which solves the problem of the existing technology that the support and fixation inside the feeding bottle causes the inside of the bottle to have a dead corner for cleaning. Through the rubber fixing ball 62, the bottle body support structure 6 adopts soft support, and a variety of feeding bottles of different specifications can be placed stably, making the shelf of the present invention suitable for all kinds of feeding bottles. The rubber fixing ball 62 and the bottle body achieve point support, further avoiding the problem of cleaning dead corners caused by the support component and the bottle body performing surface support.

[0047] like Figure 3 As shown, there are height differences between the four support columns 61, with two of the four support columns 61 being higher than the other two. Since baby bottles vary in shape, the four support columns 61 have different heights to facilitate the securement of baby bottles of varying sizes. The washing basket 1 is provided with tilted support rods for supporting the mouths of inverted baby bottles, allowing the baby bottles to be positioned at an angle after being secured. Furthermore, the four support columns secure the baby bottles at an angle after being secured, facilitating water control after washing.

[0048] In actual application, the support column 61 is retractable or made of elastic material. The support column 61 is retractable, which is convenient for fixing feeding bottles of different sizes. The support column 61 is made of elastic material and can be convenient for fixing feeding bottles of larger sizes.

[0049] The nipple securing structure 7 includes three nipple securing ribs 7-1 arranged in a triangular shape or evenly spaced around the center of a circle on the washing basket 1. The nipple securing ribs 7-1 are generally hook-shaped, with their bases secured to the washing basket 1 and their tips angled toward the center. In practice, the number of nipple securing ribs 7-1 can be one, two, or more, depending on the desired position and stability.

[0050] The three nipple-holding ribs 7-1, along with the ribs at the bottom of the washing basket 1, create a space for the nipple. The top of the nipple is secured by the three nipple-holding ribs 7-1. Because the nipple is made of a flexible material, the three nipple-holding ribs 3-1 are hook-shaped. The contact between the spoon-shaped tip and the nipple can be considered a flexible, soft contact fixation. This point contact eliminates the problem of blind spots in washing.

[0051] The ribs of the washing basket 1 at the nipple support structure 7 are arranged at an angle. One of the three nipple fixing ribs 7-1 is higher than the other two. The higher nipple fixing rib 7-1 extends downward, and the lower nipple fixing rib 7-1 extends upward. After the nipple is fixed, it is placed at an angle to facilitate washing and water control.

[0052] In order to enhance the fixing strength of the nipple, a fixing protrusion 7-2 is downwardly provided at the bottom of the extended portion of the nipple fixing rib 7-1, and the fixing protrusion 7-2 is fixed in point contact with the nipple.

[0053] In order to prevent the nipple from being scratched, the places where the three nipple fixing ribs 7-1 and the fixing protrusion 7-2 contact the nipple are rounded.

[0054] The supporting and fixing components include four nipple fixing mounting seats 9, and the nipple fixing mounting seat 9 includes two corresponding front and rear seat bodies 9-1. The bottom of the seat body 9-1 is fixed to the washing basket 1. The seat body 9-1 is cylindrical, and the distance between the two seat bodies 9-1 is short, which is convenient for fixing the nipple fixing.

[0055] An extension 9-2 is provided on the top of the base 9-1. This extension 9-2 is used to limit the displacement of the nipple holder. The extension 9-2 extends outward through the center hole of the nipple holder, allowing the nipple holder to swing within the dishwasher during washing, facilitating cleaning of the contact area with the extension 9-2. In this embodiment, the extension 9-2 is circular, and the angle between the circular extension 9-2 and the base 9-1 is 80°, which securely locks the nipple holder. This angle can be adjusted based on the angle of the spray port 4 to ensure optimal washing results.

[0056] An area for placing milk bottle caps is provided on one side of the washing basket 1 , and an upper end bracket 10 is provided above the area. The upper end bracket 10 is used to prevent the milk bottle caps from tipping over when impacted by washing water.

[0057] The upper bracket 10 includes a barrier 10-1 and a connecting portion 10-2 that connects to the washing basket 1. The barrier 10-1 is wavy and striped, compact, and has a large blocking surface, effectively preventing bottle caps from tipping over when impacted by wash water. The connecting portion 10-2 is rotatably connected to the washing basket 1, allowing the upper bracket 10 to be rotatably secured to the washing basket 1 via the connecting portion 10-2, making it easy to place and remove bottle caps.

[0058] The dishwasher provided by the present invention utilizes point-contact fixation between the support and fixing components and the tableware, solving the problem of poor cleaning performance at contact points and eliminating blind spots. The bottle support structure 6, the nipple support structure 7, and the nipple fixing mounting base 8 provide separate fixed support structures for children's tableware such as bottles and nipples. Combined with the spray system, this effectively positions and secures plastic tableware of varying types and sizes, improving washing efficiency.

[0059] The washing basket 1 also includes a support member 11, which is combined with Figure 4 and Figure 5 As shown, the support member 11 includes a support base 111 fixedly connected to the washing basket 1, a column 112 rotatably mounted on the support base 111, and a plurality of outwardly extending suspension arms 113 formed at the upper end of the column 112 for mounting wash items. The suspension arms 113 are suitable for mounting items such as baby teethers or, in daily life, small tableware.

[0060] The suspension arm 113 is a curved columnar body extending from the column 112. The suspension arm 113 has at least a first suspension point 113a and a second suspension point 113b, and a limiting structure 114 is provided between the first suspension point 113a and the second suspension point 113b to prevent the washing object mounted on the suspension arm 113 from moving between the first suspension point 113a and the second suspension point 113b. The first suspension point 113a and the second suspension point 113b are spaced a certain distance apart so that a certain gap is left between the washing objects, which is more conducive to cleaning.

[0061] Preferably, the limiting structure 114 is a columnar protrusion extending upward from the suspension arm 113 , the top of the columnar protrusion is higher than the first suspension point 113 a and the second suspension point 113 b , and the columnar protrusion also serves to strengthen the suspension arm 113 .

[0062] The central axis of the column 112 is vertically arranged, the suspension arm 113 extends outward along the radial direction of the column 112, and the outer diameter of the suspension arm 113 gradually decreases along the extending direction.

[0063] The middle of the suspension arm 113 is bent to form a lower notch. The first suspension point 113a is located at the junction of the suspension arm 113 and the column 112, and the second suspension point 113b is located in the lower notch. The suspension arm 113 is smoothly bent to avoid stress concentration. If the washing object is hung incorrectly, it will automatically slide to the first suspension point 113a or the second suspension point 113b under the action of gravity.

[0064] Support base 111 is connected to washing basket 1 via connecting ribs. A mounting opening is provided at the top of support base 111, into which the lower end of upright post 112 is inserted and pivotally engages. When a large number of items are placed in washing basket 1, the position of suspension arm 113 can be adjusted by rotating upright post 112 to fully utilize the washing space within the dishwasher.

[0065] In this embodiment, there are three suspension arms 113, which are horizontally distributed at an angle of 120 degrees with the axis of the column 112 as the center. In actual application, the number, location and direction of the suspension arms 113 can be set as needed.

[0066] like Figures 6 to 11 As shown, within the washing space, a washing water passage 2 is provided at the bottom of the inner tank, and a water channel 13 is formed on the washing water passage 2. The water channel 12 is connected to the tap water pipe through a pipeline to provide washing water. The washing water passage 2 includes a first spray arm 21 and a bottle cleaning water channel 22 connected to the water channel 13. A water pump (not shown in the figure) is also configured inside the washing space to drive the washing water in the water channel 13 to flow toward the first spray arm 21 and / or the bottle cleaning water channel 22, and spray the washing water from the spray port 4 provided on the first spray arm 21 and / or the bottle cleaning water channel 22 at a certain pressure to clean the washing objects. A plurality of spray ports 4 are provided on the upper surface of the bottle cleaning water channel 22, and in particular, a spray port 4 is provided at each supporting and fixing component to effectively clean the tableware placed on the supporting and fixing component.

[0067] The washing basket 1 is also provided with a dish placement area, and the first spray arm 21 is located below the dish placement area. The first spray arm 21 rinses the washing objects placed in the dish placement area and on the suspension arm 113 by spraying washing water.

[0068] The first spray arm 21 is configured to spray washing water toward the washing object in a rotating manner. The first spray arm 21 is installed on the upper shell of the washing water passage 2 in a freely rotatable manner. Specifically, the center of the first spray arm 21 is connected to the washing water passage 2 through a rotary joint 212 and communicates with the water channel 13. The first spray arm 21 is provided with a plurality of spray ports 4 inclined according to a certain pattern. The water flow sprayed from the spray ports 4 generates a reaction force to drive the first spray arm 21 to rotate.

[0069] The bottle-washing water channel 22 is connected to the wash water channel 2 via a detachable connector 223. It comprises a channel housing fixed to the dishwasher as a whole, and a spray column 224 disposed on its upper surface, extending into the interior of the bottle to be cleaned. The top of the spray column 224 is provided with a spray port 4 for spraying water into the bottle. The height of the spray column 224 is preferably 5 to 15 cm, and its outer diameter is smaller than the inner diameter of the bottle opening. During cleaning, the spray column 224 does not contact the bottle, thus avoiding blind spots caused by contact.

[0070] The bottle washing water circuit 22 also includes a second spray arm 226 rotatably mounted on the channel housing. The second spray arm 226 is positioned away from the first spray arm 21 and is also configured to rotate and spray wash water toward the wash objects.
