Background technique

Clothes, food, housing and transportation are essential in people's lives today. In family life, it is often necessary to cook and stir-fry in the kitchen. Because cooking oil and food are heated at high temperature, they will decompose over time to produce a large amount of food. Soot, accompanied by a pungent odor, is an indoor air pollutant. Not only will it endanger the health of the cooking staff, but it will also leave hard-to-remove stains on the wall of the kitchen and may cause the skin of the wall to fall off.

To remove oil fumes, a range hood is installed in many kitchens. The hood can absorb the fumes generated in the kitchen, thereby purifying the indoor air and preventing the cooking staff from being choked by the fumes. During the use of the range hood, the absorbed and removed oil fume will continue to adhere to the range hood components, such as the oil net or the oil cup, which will significantly reduce the cleaning ability of the range hood over time. Therefore, it needs to be manually disassembled and cleaned. . However, when manually cleaning the oil net or oil cup, there are often a lot of oil stains on it, and most of them are heavy oil stains. It is extremely difficult to clean, and it will also make the pool full of oil stains, and it is very inconvenient to clean the pool.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

As shown in FIGS. 1 and 2 , in order to solve the problem that the mesh parts of the existing range hood are inconvenient to wash and the spray cleaning effect when washing with a dishwasher is not ideal, the present invention provides a range hood for washing with a dishwasher. The method of mesh component, the dishwasher includes a washing part (not shown in the figure), a liquid driving part (not shown in the figure) and a heating part (not shown in the figure), and the washing part is provided with sequentially from top to bottom The upper spray arm 1, the middle spray arm 2 and the lower spray arm 3 are all communicated with the liquid driving part. The top and bottom of the middle spray arm 2 are provided with spray parts, and the washing part is located on the upper spray arm 1 The part between it and the middle spray arm 2 is the upper washing area, and the part of the washing part between the lower spray arm 3 and the middle spray arm 2 is the lower washing area; ) in the lower wash area.

S01. Pre-washing step: the heating part heats the washing water to a set pre-washing temperature (take 70°C as an example), before the temperature of the washing water reaches the set 70°C (for example, 60-67°C) or after (maintaining When the temperature is 70°C), the liquid driving part transports the washing water to the washing part through the spray part of the upper spray arm 1, the spray parts on both sides of the middle spray arm 2 and the spray part of the lower spray arm 3 at the same time The surface of the reticulated part of the range hood, and the water vapor filled the washing part is formed, and the oil stains are infiltrated by the washing water and water vapor until the height of the washing water exceeds the height of the reticulated part of the range hood, at the same time or after heating The washing part heats the washing water to the set pre-wash temperature (take 70°C as an example), and then stops heating, and soaks the oil stains on the surface of the mesh part of the range hood set in the washing part. During the soaking period, the liquid driving part will wash the washing water It is sent to the washing part by spraying to realize the cyclic washing and soaking of the mesh parts of the range hood. It is difficult to achieve effective flushing by simply rinsing the mesh parts of the range hood, and the simple immersion lacks fluidity and cannot achieve good cleaning. Therefore, for the cleaning of the mesh parts of the range hood, the present invention proposes a method. The new washing method, that is, the cycle of rinsing and soaking.

After the water in the washing part submerges the mesh part of the range hood, the mesh part of the range hood is soaked in hot water for 2 minutes, and then washed down by the middle spray arm 2 or the middle spray arm 2 and the lower spray arm 3 together Spray the area for 30 seconds to complete a cycle. By spraying, the water flows, which can speed up the soaking speed. After continuing for the set pre-wash time (for example, 10 minutes), the wash water is drained.

In the process of washing water spraying, water vapor filling the washing part is formed in the washing part, and the mesh parts of the range hood in the lower washing area are infiltrated by the washing water spraying, water vapor and soaking. It can realize layer-by-layer immersion of multi-layer oil stains, can immerse deeper, and cover oil stains comprehensively. Through high temperature and added detergent, the oil stains can be fully infiltrated, softened and initially decomposed, which is better than simple washing. Makes subsequent washing steps easier to operate and more thorough.

S02, washing step: the heating part heats the washing water to a set washing temperature (take 75°C as an example) and continuously or intermittently heats it to maintain the washing temperature, when the temperature of the washing water reaches the set washing temperature before or after, The liquid driving part transports the washing water into the washing part through the spray part of the upper spray arm 1, the spray parts on both sides of the middle spray arm 2 and the spray part of the lower spray arm 3, and the net parts of the range hood are cleaned. Perform cyclic rinsing and soaking when the height of the water surface in the washing section exceeds the height of the mesh part of the range hood, and continues for the set washing time (take 10 minutes as an example).

During the spraying process, the simultaneous spraying of the three spraying arms can speed up the water intake. After spraying for 1 minute, make the height of the water surface in the washing part exceed the height of the mesh part of the range hood, then stop the spraying to soak the mesh part of the range hood for 1 minute, and drain the water in the washing part within 30 seconds. cycle. The washing effect of oil stains is improved by alternating soaking and spray washing.

S03, rinsing step: the heating part heats the washing water to the set first rinsing temperature (take 50°C as an example), and then stops heating, and when the temperature of the rinsing water reaches the set first rinsing temperature or after, the liquid drives The washing water is simultaneously transported to the inner surface of the upper washing area and the lower washing area through the spraying part of the upper spraying arm 1, the spraying parts on both sides of the middle spraying arm 2 and the spraying part of the lower spraying arm 3 The surface of the range hood reticulated part is clean, and the height of the water surface does not exceed the bottom height of the range hood mesh part in the lower washing area, clean the range hood mesh part set in the washing part, and continue for the set first rinsing time. After (for example, 12 minutes), the rinse water is drained.

Through rinsing, the oil stains washed in the washing step are thoroughly rinsed, so as to avoid oil stains adhering to the interior of the washing part or re-attaching to the mesh parts of the range hood.

S04, disinfection step: the heating part heats the rinsing water to the set second rinsing temperature (take 45°C as an example) and then stops heating, and when the temperature of the rinsing water reaches the set second rinsing temperature before or after, the liquid drives The washing water is transported to the surface of the mesh part of the range hood in the lower washing area through the spraying part of the lower spraying arm 3 and the spraying part at the bottom of the middle spraying arm 2, and continues for the set second rinsing time (with 10 minutes for example).

Then the heating part heats the rinsing water to the set disinfection temperature (take 78°C as an example) and continuously or intermittently heat to maintain the disinfection temperature (take 78°C as an example), when the temperature of the rinse water reaches the set disinfection temperature (take 78°C as an example) 78°C for example) before or after), the liquid driving part simultaneously transports the washing water to the range hood mesh part of the lower washing area through the spraying part of the lower spraying arm 3 and the spraying part at the bottom of the middle spraying arm 2 On the surface, cyclically rinse and soak the mesh parts of the range hood set in the washing part. After spraying for 1 minute, make the height of the water surface in the washing part exceed the height of the mesh part of the range hood, then stop the spraying to soak the mesh part of the range hood for 1 minute, and drain the water in the washing part within 30 seconds. cycle. Continuously set disinfection time (take 10 minutes as an example).

After the rinsing step in step S03, there may still be a very small amount of oil stains remaining, and some oil stains remain on the inner wall of the dishwasher. In order to rinse thoroughly, the disinfection step is divided into two steps. First, the rinse water is heated to the second The rinsing temperature (take 45°C as an example), and then implement the same or similar steps as the rinsing step to achieve thorough cleaning, then heat the rinse water to the disinfection temperature, and then perform the final disinfection and rinsing. At the same time, the purpose of final cleaning and sterilization is achieved.

S05, drying step: open the door or cover of the dishwasher to communicate with the outside world, and use the residual heat of the washing part and the reticulated part of the range hood or use the fan to discharge the moisture in the washing part to the outside.

Open the door (not shown in the figure) or cover (not shown in the figure) of the dishwasher to communicate with the outside world, and use the residual heat of the washing part and the mesh part of the range hood or use the fan (not shown in the figure) to wash the washing machine. The moisture inside is exhausted to the outside.

When the sterilization is completed, the cleaning of the mesh parts of the range hood has been completed. Finally, in order to prevent condensation in the dishwasher and to dry the mesh parts of the range hood, the door of the dishwasher is opened and selectively activated. The fan is used to remove moisture and avoid condensation, and because the mesh part of the range hood is cleaned by high-temperature water, it absorbs part of the heat itself, which is enough to dry the residual rinsing water on the surface, with the function of the fan , which can realize the overall drying of the mesh parts of the range hood.

It should be noted that, in the above-mentioned overall solution, in order to avoid the condensation of oil stains during the washing process and cause the oil stains to adhere to the interior of the washing part, and to avoid the damage to the mesh parts of the range hood being washed due to excessive temperature difference changes, all equipment The set temperatures are all greater than the temperature threshold, taking 40°C as an example. In order to achieve a good disinfection effect, a higher value is selected for the disinfection temperature, taking 78°C as an example. In order to improve the efficiency of washing and the effect of removing oil stains, it is also necessary to set the washing temperature to a higher temperature, but it does not need to exceed the temperature of sterilization and disinfection. Therefore, the washing temperature is not greater than the disinfection temperature. Take 75°C as an example. The pre-wash step is used to initially remove oil stains. The pre-wash temperature does not need to reach the washing temperature. Therefore, the pre-wash temperature is lower than the washing temperature, but it should not be too different. Take 70°C as an example. The rinsing step is to clean the residual oil stains. In order to speed up the washing and reduce the energy consumption, there is no need to reheat to a very high temperature. The first rinsing temperature is lower than the washing temperature, taking 50°C as an example. For thorough rinsing, the second rinsing temperature does not need to be heated to a very high temperature, such as 45°C.

It should be noted that the above-mentioned embodiments are only used to illustrate the principle of the present invention, and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure to facilitate the present invention. The invention can be applied to more specific application scenarios.

For example, in an alternative embodiment, although the method for cleaning the mesh part of a range hood with a dishwasher in the description is described by including a pre-washing step as an example, it is obvious that other solutions can be adopted in the present invention, For example, excluding the pre-washing step and directly entering the washing step, the function of cleaning the mesh parts of the range hood can also be well completed.

For example, in another alternative embodiment, since there is already a special rinsing step, further rinsing in the sterilization step can obviously also be removed, which does not deviate from the principle of the present invention, and therefore falls within the scope of the present invention. within the scope of protection of the invention.

For example, in another alternative embodiment, the washing parts placed in the lower washing area are not limited to the mesh parts of the range hood, such as oil meshes, etc., but can also be other mesh-shaped parts with oil stains, such as barbecue meshes, Chopstick cages, etc., all of which do not deviate from the principles of the present invention, and therefore fall within the protection scope of the present invention.

To sum up, the present invention makes the whole washing process without cooling stage through the special step design, thus avoiding the condensation and re-attachment of oil stains, and rationally distributes the temperature of each step to reduce the heating time of the heater as much as possible, so as to make the whole washing process easier. The washing process takes less time, and the energy consumption is within a reasonable range instead of uniform high-temperature treatment. Through the cyclic washing and soaking treatment, the oil stains similar to the mesh parts of the range hood are cleaned more thoroughly.
