Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, specifically to an internal water pipe structure for a cleaning machine and the cleaning machine itself. Background Technology

[0002] For countertop and cabinet dishwashers, due to their large washing space, they are generally designed with three spray arms: top, middle, and bottom, in order to achieve better washing results. The middle and top spray arms are supplied with water through an inner water pipe that extends upward close to the inner wall of the washing chamber.

[0003] After a dishwasher finishes washing, dishes often need to be dried to prevent bacterial growth. If residual water inside the cavity and components is not effectively removed, it will cause unpleasant odors to develop over time, affecting the customer's user experience. For details, please refer to Chinese Patent Application No. CN 201811068318.8, "A Dishwasher".

[0004] For internal water pipes, which are typically made of PP material, the surface tension of water causes some water droplets to adhere to the pipe's wall surface. To achieve a water-free surface and interior, common methods include:

[0005] First, the internal water pipes are dried by controlling the timing of the addition of rinsing agent. However, the rinsing agent contains chemical components that can easily remain on the surface of the tableware, affecting the health of users.

[0006] Secondly, the water absorbs the residual water in the inner water pipe through water-absorbing minerals. However, the water-absorbing minerals are disposable and need to be replaced after a period of time, which is costly. In addition, the whole machine is heavy and not easy to move.

[0007] Third, a high-power heating and drying device is used to dry the inner water pipes. However, high-power heating and drying devices are more energy-efficient and require more electricity to dry the same washing scenario. Utility Model Content

[0008] The first technical problem to be solved by this utility model is to provide an inner water pipe structure for a cleaning machine that is simple in structure and can reduce residual water on the surface of the inner water pipe, in light of the current state of the prior art.

[0009] The second technical problem to be solved by this utility model is to provide an inner water pipe structure for a cleaning machine that can reduce the residual water inside the inner water pipe.

[0010] The third technical problem to be solved by this utility model is to provide a cleaning machine that uses the above-mentioned internal water pipe structure.

[0011] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: an inner water pipe structure for a cleaning machine, including an inner water pipe, the bottom of which has a first pipe section extending from front to back along the flow direction of water flow, characterized in that: a first guide rib extending in the front-back direction is protruding on the upper surface of the first pipe section, the first guide rib dividing the upper surface of the first pipe section into two relatively independent first guide surfaces, each of the first guide surfaces gradually decreasing from the first guide rib toward the side edge of the first pipe section.

[0012] For ease of processing, the first guide surface is an inclined surface.

[0013] To avoid taking up too much space, the tilt angle of the first guide surface is 4 to 6 degrees.

[0014] To prevent water from accumulating at the bottom of the inner water pipe, the lower surface of the first pipe section includes two second guide surfaces arranged symmetrically from left to right, with each second guide surface gradually decreasing in elevation from the side edge of the first pipe section toward the junction of the two second guide surfaces.

[0015] For ease of processing, the second guide surface is an inclined surface.

[0016] To avoid taking up too much space, the inclination angle of the second guide surface is 4 to 6 degrees.

[0017] To further address the second technical problem mentioned above, a second guide rib is provided on the bottom wall inside the first tube, which is inclined downward from back to front. The second guide rib divides the bottom wall inside the first tube into two relatively independent third guide surfaces, and each third guide surface gradually decreases from the side edge of the first tube towards the second guide rib.

[0018] For ease of processing, the third guide surface is an inclined surface.

[0019] To avoid occupying too much space, the inclination angle of the third guide surface is 4 to 6 degrees.

[0020] The technical solution adopted by this utility model to solve the third technical problem mentioned above is: a cleaning machine, characterized in that: it applies the above-mentioned internal water pipe structure.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] (1) By setting a first guide rib and a first guide surface on the upper surface of the first pipe, on the one hand, the setting of the first guide surface can cause the residual water to move in the width direction on both sides of the first pipe, and on the other hand, the setting of the first guide rib causes the residual water to move in the length direction of the first pipe. The composite angle drainage effectively removes the residual water on the upper surface of the first pipe, thereby reducing the residual water on the surface of the inner water pipe, and the structure is simple.

[0023] (2) By setting a second guide surface on the lower surface of the first pipe, on the one hand, water can be prevented from hanging at the bottom of the first pipe, and on the other hand, dirt can be reduced in the gap between the inner water pipe and the bottom of the sheet metal of the cleaning machine, thus improving the user experience.

[0024] (3) By setting a second guide rib and a third guide surface on the bottom wall inside the first pipe section, on the one hand, the setting of the third guide surface can cause the residual water to gather around the second guide rib, and on the other hand, the setting of the second guide rib causes the residual water to move in the direction of the length of the first pipe section, helping the internal water to be discharged through the water inlet of the inner water pipe, thereby reducing the residual water inside the inner water pipe and avoiding problems such as odor caused by long-term internal water storage.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0031] like Figures 1 to 4 The image shows a preferred embodiment of the cleaning machine with an internal water pipe structure according to the present invention. The internal water pipe structure includes an internal water pipe 1.

[0032] The inner water pipe 1 includes a first pipe section 11 extending from front to back along the water flow direction, a second pipe section 12 extending upward from the rear end of the first pipe section 11, and a third pipe section 13 extending forward from the top end of the second pipe section 12. The inlet end of the first pipe section 11 is used to connect to the water pump of the cleaning machine, and the outlet end of the third pipe section 13 is used to connect to the top spray arm of the cleaning machine. This is the conventional structure of the cleaning machine, and will not be described in detail here.

[0033] In this embodiment, a first guide rib 111 extending in the front-rear direction is provided on the upper surface of the first pipe 11. The first guide rib 111 divides the upper surface of the first pipe 11 into two relatively independent first guide surfaces 112. Each first guide surface 112 gradually decreases from the first guide rib 111 toward the side edge of the first pipe 11. In this way, on the one hand, the arrangement of the first guide surface 112 can cause the residual water to move in the width direction on both sides of the first pipe 11. On the other hand, the arrangement of the first guide rib 111 causes the residual water to move in the length direction of the first pipe 11. The combined angle drainage effectively removes the residual water from the upper surface of the first pipe 11.

[0034] In this embodiment, the lower surface of the first pipe 11 includes two second guide surfaces 113 arranged symmetrically from left to right. Each second guide surface 113 gradually decreases from the side edge of the first pipe 11 to the connection of the two second guide surfaces 113. In this way, on the one hand, water can be prevented from hanging at the bottom of the first pipe 11, and on the other hand, dirt can be reduced in the gap between the inner water pipe 1 and the bottom of the sheet metal of the cleaning machine, thus improving the user experience.

[0035] In this embodiment, a second guide rib 114, which is inclined downwards from back to front, is provided on the bottom wall inside the first pipe section 11. The second guide rib 114 divides the bottom wall inside the first pipe section 11 into two relatively independent third guide surfaces 115. Each third guide surface 115 gradually decreases from the side edge of the first pipe section 11 towards the second guide rib 114. In this way, on the one hand, the arrangement of the third guide surface 115 can cause the residual water to gather around the second guide rib 114. On the other hand, the arrangement of the second guide rib 114 causes the residual water to move in the length direction of the first pipe section 11, helping the water stored inside to be discharged through the water inlet of the inner water pipe 1, avoiding problems such as odor caused by long-term water storage inside.

[0036] In this embodiment, the first guide surface 112, the second guide surface 113, and the third guide surface 115 are all inclined surfaces, and the inclination angles of the first guide surface 112, the second guide surface 113, and the third guide surface 115 are all 4 to 6 degrees. The processing is simple and does not take up too much space.

[0037] The working principle of this embodiment is as follows: When the cleaning is finished, the residual water in the third pipe section 13 and the second pipe section 12 will fall back to the first pipe section 11. With the setting of the guide ribs and guide surface on the inner and outer surfaces of the first pipe section 11, combined with the efficient and energy-saving PTC hot air drying technology, the residual water inside and outside the inner water pipe 1 can be effectively removed, and the structure is simple.
