DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0032] The utility model designs a kind of dish washer, as shown in Figures 1-2 、 Figure 6 The utility model discloses a kind of dish washer, as shown in Figures 1-2 、 Figure 6 The water inlet pipe 3 is communicated with one end of the spray arm 1, the spray arm 1 has water flow passage inside, a plurality of water outlets 7 communicated with the water flow passage are formed in the spray arm 1, and the spray arm 1 is placed in the containing groove 171 and connected with the bowl basket 17 at both ends.
[0033] The spray arm 1 with water flow passage inside is installed into the containing groove 171 in the bottom of the bowl basket 17, in addition to providing mounting space for the spray arm 1, the containing groove 171 is more important to cooperate with the spray arm 1 and the bowl basket 17, and constitutes the layout structure that the spray arm 1 is embeddedly installed into the bottom of the bowl basket 17. Such layout can avoid the spray arm 1 from causing blocking interference to the lower bowl basket 17 in the same dish washer, and affect the capacity and placing height of the lower bowl basket 17 on the one hand. On the other hand, the spray arm 1 can be deeply placed into the interior of the bowl basket 17 to obtain better spray view, so that when the water flow passage in the spray arm 1 is connected with the water inlet pipe 3 in the water system, the spray arm 1 can directly spray water in the interior of the bowl basket 17, and cups and small dishes placed at the center position of the bowl basket 17 can be fully washed, so that the situation that tableware is not completely cleaned is avoided.
[0034] The spray arm 1 can be designed as a tubular structure with a triangular cross section. The tubular structure of the spray arm 1 is installed below the bowl basket 17, the bottom of which is divided into two left and right placement areas, and the user can place the cup or the dish in an inclined or upside-down manner on the first placement area 172 and the second placement area 173. Because the cross section of the spray arm 1 is triangular, the two inclined surfaces on the upper side, i.e. the first side wall 4 and the second side wall 5, are just directed towards the first placement area 172 and the second placement area 173 on both sides of the bowl basket 17, and can make the cleaning water flow sprayed from the water outlets 7 on the surfaces of the first side wall 4 and the second side wall 5 be able to hit the inside of the inclined cup and the inner surface of the upside-down placed dish in an upward angle, thereby achieving the purpose of fully cleaning the cup and the dish.
[0035] Of course, the specifications of the water outlets 7 on the first side wall 4 and the second side wall 5 can be flexibly arranged and combined according to different cleaning objects.
[0036] In addition, the first side wall 4 and the second side wall 5, as the two inclined surfaces on the upper side of the spray arm 1, can not only provide space for the water outlets 7 and meet the needs of water flow at different incident angles of the dish and the cup, but also the inclined surfaces can facilitate the oil stains or food residue falling from the upper layer of the bowl basket 17 or the tableware to quickly slide away, thereby avoiding the blockage of the water outlets 7 on the first side wall 4 and the second side wall 5 or the change of the spraying direction, and affecting the cleaning effect.
[0037] At the same time, in order to make the bottom cover 8 provided with the drainage slope 9 and the drainage opening 10 more convenient to produce and manufacture, reduce the manufacturing difficulty, the bottom cover 8 is manufactured separately from the spray arm 1, and then the bottom cover 8 is assembled below the spray arm 1 to complete the fixed installation of the bottom cover 8.
[0038] Furthermore, in order to avoid the residual cleaning water in the closed spray arm 1 to easily breed bacteria in a humid environment, causing pollution of the cleaning water and further pollution of the tableware. Therefore, the drainage slope 9 is arranged on the surface of the bottom cover 8, when the spray arm 1 is no longer filled with cleaning water, the residual cleaning water in the spray arm 1 will slide down along the drainage slope 9 to the bottom of the drainage slope 9, and then flow out to the outside of the spray arm 1 through the drainage opening 10 at the bottom of the drainage slope 9, so as to ensure that the inside of the spray arm 1 is as dry as possible and reduce the breeding of bacteria.
[0039] In addition, since the water outlets 7 are arranged along the length direction of the spray arm 1, when the water pressure is constant, the closer to the water inlet pipe 3 the water outlet 7 is, the stronger the water pressure is, and the stronger the cleaning ability is. In order to avoid the problem of large difference in cleaning ability, a buffer portion 2 is arranged at one end of the spray arm 1 in the embodiment, which can not only buffer the impact of instantaneous water flow on the spray arm 1 to cause the problem of loose installation, but also store water in the internal cavity to match the water inlet amount, so that the flow of the water outlets 7 at different positions is as uniform as possible, to avoid the case of large difference in cleaning effect.
[0040] As shown in Figure 6 , the spray arm 1 in the embodiment is fixedly installed on the basket 17, and in order to be convenient, the basket 17 needs to be pulled out of the dishwasher during the process of putting and taking tableware. This means that the spray arm 1 which goes in and out with the basket 17 must solve the problem of how the water inlet pipe 3 is connected with the spray arm 1. Figure 7 As shown in , the water inlet pipe 3 is fixed in the dishwasher, and the connecting hole 12 on the spray arm 1 is concentric with the pipe opening of the water inlet pipe 3. When the basket 17 slides along the side wall of the dishwasher to the inside under the action of the rollers, the water inlet pipe 3 will gradually insert into the connecting hole 12, and the sealing ring 14 in the connecting hole 12 will seal the connecting position due to its elasticity and extrusion, thereby completing the connection of the spray arm 1 with the water inlet pipe 3. When the basket 17 needs to be pulled out, only the basket 17 needs to be pulled, and the spray arm 1 which moves with the basket 17 will automatically separate from the water inlet pipe 3, that is, the water inlet pipe 3 will not cause any obstacle to the movement of the spray arm 1. At the same time, in order to ensure the smoothness and stability during the connection process, the guide piece 13 designed at the opening of the connecting hole 12 can correct and align the offset connecting track through the sliding of the pipe opening of the water inlet pipe 3 and the guide piece 13.
[0041] Figures 3-5 As shown in , the spray arm 1 is installed on the basket 17, and the spray arm 1 is a tubular structure. In order to match the shape and structure, two mounting plates, i.e. the front mounting plate 15 and the rear mounting plate 16, are designed, and two clamping sleeves, i.e. the front end clamping sleeve and the rear end clamping sleeve, which match the shapes of the two ends of the spray arm 1, are extended below the front mounting plate 15 and the rear mounting plate 16. During the installation process, only the two ends of the spray arm 1 need to be inserted into the corresponding front end clamping sleeve and rear end clamping sleeve, and the assembly between the connecting structure and the spray arm 1 can be completed.
[0042] The existing bowl basket 17 is basically made of strip-shaped metal bending and weaving, so in order to adapt to the structure of the bowl basket 17, the buckle 6 is arranged on the surface of the rear mounting plate 16, when the strip-shaped metal on the bowl basket 17 slides into the interior of the buckle 6 through the opening of the buckle 6, the installation of the rear mounting plate 16 on the bowl basket 17 is completed; and the front mounting plate 15 is spliced by two parts, and the joint is also designed with the matching groove 18 matched with the shape and size of the strip-shaped metal, so that when the two parts of the front mounting plate 15 clamp the side wall of the bowl basket 17 to complete closure, the strip-shaped metal will be limited by the matching groove 18, and the installation of the front mounting plate 15 on the bowl basket 17 is realized.
[0043] Therefore, the front mounting plate 15 and the rear mounting plate 16 installed on the bowl basket 17 can realize the installation and fixation of the spray arm 1, so as to achieve the purpose of installing the spray arm 1 at the bottom of the bowl basket 17.
[0044] In order to avoid that the spray arm 1 protrudes between the adjacent two bowl baskets 17, causing unnecessary obstruction to the upper space of the bowl basket 17, the accommodation groove 171 is arranged on the bottom surface of the bowl basket 17, which provides installation space for the installation of the spray arm 1. In addition, it should be noted that, in addition to providing space for the installation of the spray arm 1, the accommodation groove 171 is more important, which can make the water outlet 7 on the spray arm 1 penetrate into the interior of the bowl basket 17, so that the cups and dishes placed in the first placing area 172 and the second placing area 173 can be washed by the water flow sprayed by the water outlet 7, and the effect of thorough cleaning is achieved.
[0045] In addition, in order to further strengthen the accuracy and stability of the butt joint of the water inlet pipe 3 and the butt joint hole 12, the guide rod 21 is arranged on the surface of the rear mounting plate 16, the length of the guide rod 21 is relatively long, which can ensure that the butt joint hole 12 and the pipe opening of the water inlet pipe 3 are always in concentric state through the limiting sliding of the guide groove 22 during the pushing back of the bowl basket 17, and the butt joint accuracy is guaranteed.
