Description

Technical Field

[0001] This utility model relates to the field of washing equipment technology, specifically a heating circulating water circuit structure for a washing equipment and a washing equipment having the same structure. Background Technology

[0002] The water system of washing equipment, especially dishwashers, is its core working component, and its design directly affects the cleaning efficiency, energy consumption, and reliability of the equipment. Currently, common dishwasher water systems on the market mainly suffer from spatial layout and integration issues: traditional water systems often use a vertical layout between the water pump's inlet and outlet pipes, and the heating element often employs a bent and rotating structure, as seen in Chinese invention patent CN20191022335.0. This layout is loosely structured, occupies a large space, and generates high water flow resistance. This reduces the utilization rate of the dishwasher's internal space, directly limiting the miniaturization design of washing equipment. Therefore, there is an urgent need for a more compact heating and circulating water system structure for washing equipment with lower flow resistance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heating circulating water circuit structure for a washing equipment, which has higher space utilization and lower water flow resistance, in response to the above-mentioned technical deficiencies.

[0004] In a first aspect, this utility model provides a heating circulating water circuit structure for a washing equipment, including a water pump and a heater. The water inlet pipe of the water pump is connected to the water collection part of the washing equipment, and the water outlet pipe of the water pump is connected to the water inlet port of the heater. The water outlet port of the heater is connected to the water supply part of at least one spray arm through a pipeline. The central axis of the water pump's inlet pipe is set in opposite directions and parallel to the central axis of the outlet pipe. The heater is a straight-tube heater, and the axis of its heating tube is coaxial with the axis of the water pump's outlet pipe.

[0005] To further optimize this technical solution, the water pump in the heating circulating water circuit structure of a washing equipment is a centrifugal pump.

[0006] To further optimize this technical solution, the heater in the heating circulation water circuit structure of a washing equipment is a thick-film heating tube structure.

[0007] Secondly, this utility model also provides a washing device having a heating circulating water circuit structure as described in any one of the technical solutions of the first aspect above.

[0008] Unlike existing technologies, in this technical solution, the water pump and heater are arranged in a short, straight line along the pipeline between the water collection section and the water supply section of the spray arm in the washing equipment, resulting in less water flow resistance. The heater is a straight-tube heater, allowing the water to flow through its internal heating channel without bends, thus minimizing resistance. Furthermore, its heating element is located on the outer wall of the water flow channel, enabling water and electricity separation and enhancing safety.

[0009] The heated circulating water circuit structure is installed at the bottom of the washing chamber of the washing equipment. The straight water circuit layout can make better use of the space in the lower part of the inner tank and make the pipeline simpler, which helps to promote the miniaturization of the washing equipment. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] In the diagram, 1 is the washing equipment; 1-1 is the water collection section; 1-2 is the water supply section of the spray arm; 2 is the water pump; 2-1 is the inlet pipe; 2-2 is the outlet pipe; 3 is the heater; and 4 is the pipeline. Detailed Implementation

[0012] For the sake of brevity, "heating circulating water circuit structure" in this utility model is a concise expression for "a heating circulating water circuit structure for a washing device"; the washing device 1 described in this utility model can be a dishwasher, vegetable washing machine, baby bottle washing machine or similar washing device.

[0013] like Figure 1 As shown: A heating circulating water circuit structure for a washing device, comprising: It includes a water pump 2 and a heater 3. The water inlet pipe 2-1 of the water pump 2 is connected to the water collection part 1-1 of the washing equipment 1, and the water outlet pipe 2-2 of the water pump 2 is connected to the water inlet port of the heater 3. The water outlet port of the heater 3 is connected to the water supply part 1-2 of at least one spray arm through a pipe 4. The central axis of the inlet pipe 2-1 of the water pump 2 is set in opposite parallel directions to the central axis of the outlet pipe 2-2. The heater 3 is a straight tube heater, and the axis of its heating tube is coaxial with the axis of the water outlet pipe 2-2 of the water pump 2.

[0014] In this embodiment, the straight-tube heater refers to a heater 3 in which the heating element is arranged around a central heat-conducting pipe, with the interior of the central heat-conducting pipe serving as a heating channel for the liquid. This isolates the liquid from the heating element through the heat-conducting pipe, achieving water-electricity separation. The heating element can be a resistance wire coil, a PTC heating element, or a thick-film heating tube.

[0015] The water collection section 1-1 refers to the part of the washing chamber of the washing equipment 1 that collects water flow and serves as the water circulation outlet. For a dishwasher, the water collection section 1-1 is the water cup.

[0016] The water supply section 1-2 of the spray arm refers to the node that supplies water to the spray arm. It can be the pipe inlet that is directly connected to the spray arm, or it can be the inlet of the water distributor that switches the water flow between different spray arms.

[0017] To further optimize this technical solution, the water pump 2 in the heating circulating water circuit structure of a washing device is a centrifugal pump. Centrifugal pumps have lower noise and higher flow rates. Alternatively, the water pump 2 can also be a plunger pump with higher pump pressure.

[0018] To further optimize this technical solution, the heater 3 of the heating circulation water circuit structure of a washing equipment is a thick-film heating tube structure. The thick-film heating tube is a high-efficiency electrothermal element based on thick-film printing technology. Its core feature is that the heating circuit (resistance paste) is directly attached to the surface of the insulating substrate through processes such as printing and sintering to form an ultra-thin heating layer, which combines the advantages of small size, fast heating and high thermal efficiency.

[0019] Secondly, this utility model also provides a washing device 1, which has a heating circulating water circuit structure for a washing device according to any one of the technical solutions of the first aspect.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
