Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kitchen utensils, and particularly relates to a wooden product for kitchen utensils and a kitchen utensil with the wooden product. Background Art
[0002] Dishwashers can automatically clean kitchen utensils such as pots, bowls, and chopsticks, which can help people reduce the burden of housework. Therefore, the use of dishwashers is becoming more and more popular. However, common kitchen utensils, such as pots, shovels, spoons, etc., usually have wooden handles or are made of wooden materials themselves. The inside of a dishwasher is usually a cleaning environment with high temperature, high humidity, and acid-base atomization. Under such cleaning environmental conditions, it will accelerate the absorption and release of moisture in the wood, resulting in uneven expansion and contraction of the wood, and then causing problems such as deformation and cracking. At the same time, the acid-base environment will cause chemical corrosion to the wood (for example, changing its color and structure). The above situations will affect the use experience of kitchen utensils with such wood and the service life of the products. Summary of the Utility Model
[0003] Therefore, the purpose of the present utility model is to provide a wooden product and a kitchen utensil to solve the problem that the wooden products in the prior art are extremely prone to deformation, cracking, discoloration, and even corrosion during dishwasher cleaning, which affects the use experience of kitchen utensils with such wood and the service life of the products.
[0004] The purpose of the first aspect of the present utility model is to provide a wooden product that forms the handle of a kitchen utensil or serves as a kitchen utensil. The wooden product includes a wooden main body and an acrylic resin filler filled in the surface pores of the wooden main body.
[0005] According to the wooden product of the present utility model, by filling the acrylic resin filler in the surface pores of the wooden main body, the surface pores of the wooden main body can be blocked, and the acrylic resin filler has good acid-base resistance and waterproof performance, so as to ensure that the wooden product is not easily deformed, cracked, and corroded during dishwasher cleaning, and further enable the kitchen utensil to have a better use experience and product service life.
[0006] In some embodiments, the acrylic resin filler is an acrylic resin filler or an acrylic derivative resin filler. The above acrylic resin filler not only has excellent waterproof performance but also can meet the requirements of kitchen utensils for food hygiene.
[0007] In some embodiments, the formation depth of the acrylic resin filler is not higher than the range of 20 microns to 50 microns. An appropriate filling depth can ensure the basic performance (such as the structural strength of the wooden product) while avoiding unnecessary material waste and reducing processing costs.
[0008] In some embodiments, in the direction from the outside to the inside of the wood product, the number of filled pores of the wood product gradually decreases. This means that in the area near the outer surface, more pores are covered by the filler, while in the deeper area, the number of filled pores is relatively small. By setting the filling amount near the outer surface to be more than that inside, it is possible to fill the pores of the wooden body with an acrylic resin filler by a simple impregnation process without excessive pressure intervention and temperature intervention, which can achieve the purpose of sealing while simplifying the formation process of the wood product. In addition, without excessive pressure intervention and temperature intervention, the basic structure and strength of the wood product can be protected, and the reliability of long-term use can be improved.
[0009] In some embodiments, the number of filled pores on the surface layer of the wood product accounts for 90%-95% of the total number of pores on the surface layer of the wood product. It can be understood that in the surface layer area, the vast majority of pores have been covered by the filler. The high filling ratio can significantly improve the surface performance of the wood product, such as enhanced abrasion resistance, scratch resistance and waterproofness. And / or the filling rate of a single pore is 10%-30%. Within this range, it is possible to ensure the effective distribution of the filler in the pores and avoid problems that affect the strength and basic structure of the wood product caused by overfilling.
[0010] In some embodiments, a protective layer is formed on the surface of the wooden body, and the protective layer can further enhance the water resistance, aesthetics (e.g., surface flatness), acid and alkali resistance, and abrasion resistance of the wood product.
[0011] In some embodiments, the thickness of the protective layer is in the range of 3 microns to 8 microns; and / or the protective layer is an acrylic resin layer or a nano-silica film layer. Within this thickness range, the protective layer can effectively protect the wooden body and prevent the erosion of the wooden body by external environmental factors (such as moisture, stains, chemical substances, etc.). At the same time, it can also avoid problems such as cracking or peeling of the protective layer caused by being too thick, thereby extending the service life of the wood product.
[0012] In some embodiments, the surface of the wooden body has a rough structure with a roughness of not more than 2 microns. In this way, it is convenient for subsequent operations, ensures the appearance of the product, and at the same time, can improve the bonding force with the subsequent protective layer and avoid delamination.
[0013] In some embodiments, the wood product is a chopping board, a handle or a rolling pin. The diverse structural forms of the wood product can, to a certain extent, solve the problem of poor dishwasher cleaning of wooden kitchen utensils.
[0014] According to a second aspect of the present application, there is provided a kitchen utensil, wherein the kitchen utensil is made of the above-mentioned wood product, or the kitchen utensil includes a functional part and a handle connected to the functional part, and the handle is made of the above-mentioned wood product.
[0015] In some embodiments, the kitchen utensil is a pot, spatula, spoon, cutting board or rolling pin. The wood product is suitable for various types of kitchen utensils and can optimize the user experience of using the kitchen utensil. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In addition, in the description of the examples, when the detailed description of the relevant components or functions that are considered to be well-known will cause a vague interpretation of the present utility model, such detailed description will be omitted.
[0037] According to the present utility model, for the wood products used in kitchen utensils, the pores on the surface layer of the wood products are sealed with acrylic resin fillers to reduce or prevent the intrusion of moisture and other harmful substances. In this way, the wood products can resist physical and chemical damages that may be encountered in the dishwasher environment, such as high temperature, friction, acid-base corrosion, etc., thereby ensuring that the kitchen utensils have a better use experience and the service life of the products.
[0038] Next, in combination with Figures 1 to 5 the wood products provided by the embodiments of the present utility model will be introduced.
[0039] According to an embodiment of the present utility model, a wood product is provided. The wood product is made into the handle of a kitchen utensil or made into a kitchen utensil. As Figure 1 shown, the wood product 10 includes a wooden main body 11 and an acrylic resin filler 12 filled in the pores on the surface layer of the wooden main body 11.
[0040] For the wood product according to the present utility model, by filling the acrylic resin filler 12 into the surface pores of the wooden main body 11, the surface pores of the wooden main body 11 can be blocked, and the acrylic resin filler 12 has good acid and alkali resistance and waterproof performance, so that it can ensure that the wood product is not easily deformed, cracked or corroded during dishwasher cleaning, and further enables the kitchen utensils to have a better use experience and the service life of the product.
[0041] According to the present application, the wood product can be made into the handle of a kitchen utensil or made into a kitchen utensil. It can be understood that the wood product is the raw material for making the kitchen utensil. Specifically, when the wood product is made into the handle of a kitchen utensil, it can be used as the handle of a pot, a spatula, a spoon (e.g., a slotted spoon), etc. When the wood product is made into a kitchen utensil, it can be a cutting board, a rolling pin 200, a spatula, a spoon, etc. It should be noted that the handles of the above-mentioned pots, spatulas, spoons (e.g., slotted spoons), etc., and the cutting boards, rolling pins 200, spatulas, spoons, etc. have the shapes of conventional cutting boards, handles or rolling pins, and the present application does not make too many limitations on this. As an example, the cutting board can be square or round, and the handle can be long strip-shaped.
[0042] According to the present application, the surface layer refers to the area extending a certain depth from the outer surface of the wood product into the wood product. This depth range can be specifically determined according to the requirements of the filling process, the use of the wood product, the thickness and the desired performance. Correspondingly, the surface pores refer to the tiny pores naturally formed in the wood in this surface layer area. These pores may be the cell cavities, ducts or other structural gaps left during the growth of the wood, or may be generated due to damage to the wood surface during the processing. Filling to block these pores can make the wood product not easily adsorb corrosive media, stains, etc., thereby improving the durability of the wood product.
[0043] In some embodiments, the formation depth of the acrylic resin filler 12 is not higher than the range of 20 microns to 50 microns. An appropriate filling depth can avoid unnecessary material waste and reduce processing costs while ensuring the basic performance (e.g., the structural strength of the wood product). Specifically, if the formation depth of the filler is too deep, it will increase the material consumption and processing difficulty, thus increasing the cost. If the formation depth of the filler is too shallow, the long-term sealing effect may not be achieved, affecting the service life.
[0044] According to the present application, the acrylic resin filler 12 has excellent water resistance, weather resistance and chemical stability. By filling the acrylic resin filler into the surface pores of the wooden body 11, the surface pores can be effectively sealed. In this way, the wooden product can withstand the high temperature, high humidity, and acid-base atomization environmental conditions of the dishwasher. In addition, the filler exists in the pores of the wooden body and has a strong bonding force, making it not easy to escape from the pores due to the movement of the dishwasher, and can effectively prevent the wooden product from being damaged by the external environment (moisture, dishwasher cleaning environment, corrosion or pests) for a long time.
[0045] In some embodiments, the acrylic resin filler 12 is an acrylic resin filler or an acrylic derivative resin filler. Among them, the acrylic resin is a high molecular compound polymerized from acrylic acid or methacrylic acid and their derivatives (such as esters, nitriles, amides, etc.), and the acrylic derivative resin refers to a resin prepared by copolymerization or modification with other monomers or compounds based on the polymer of acrylic acid or its derivatives. As an example, the acrylic derivative resin filler can be an acrylic resin-inorganic nano hybrid filler. The above acrylic resin filler 12 not only has excellent waterproof performance but also can meet the food hygiene requirements of kitchen utensils.
[0046] In the prior art, the outer surface layer is the part of the wooden product that first comes into contact with the external environment, so it is also the area most vulnerable to wear, stains and bacterial invasion.
[0047] According to the present utility model, in the direction from the outside to the inside of the wooden product, the filling quantity of the pores of the wooden product gradually decreases. This means that in the area close to the outer surface, more pores are covered by the filler, while in the deeper area, the number of filled pores is relatively small. By making the filling quantity near the outer surface more than that inside, the acrylic resin filler 12 can be filled into the pores of the wooden body by an impregnation process at normal temperature and pressure without excessive pressure intervention and temperature intervention, so as to achieve the purpose of sealing while simplifying the formation process of the wooden product. In addition, without excessive pressure intervention and temperature intervention, the basic structure and strength of the wooden product can be protected, and the reliability of long-term use can be improved.
[0048] In some embodiments, the number of filled surface pores of the wood product accounts for 90%-95% of the total number of surface pores of the wood product. It can be understood that in the surface area, the vast majority of the pores have been filled with fillers. The high filling ratio can significantly improve the surface properties of the wood product, such as enhanced abrasion resistance, scratch resistance, and water resistance. The filling rate of a single pore represents the proportion of the filling volume of the filler in a single pore, which reflects the distribution state and compactness of the filler in the pore. As an example, the filling rate of a single pore is 10%-30%. Within this range, it can ensure the effective distribution of the filler in the pore and avoid problems that affect the strength and basic structure of the wood product caused by overfilling. If the filling rate of a single pore is too low, the requirement for performance durability cannot be met. If the filling rate of a single pore is too high, the strength and basic structure of the wood product will be affected due to overfilling.
[0049] In some embodiments, a protective layer 13 is formed on the surface of the wooden body 11. The protective layer 13 can further enhance the water resistance, aesthetics (e.g., surface flatness), acid and alkali resistance, and abrasion resistance of the wood product.
[0050] In some embodiments, the thickness of the protective layer 13 is in the range of 3 microns to 8 microns. Within this thickness range, the protective layer 13 can effectively protect the wooden body 11 from being eroded by external environmental factors (such as moisture, stains, chemicals, etc.). At the same time, it can also avoid problems such as cracking or peeling of the protective layer 13 caused by being too thick, thereby extending the service life of the wood product.
[0051] In some embodiments, the protective layer 13 is an acrylic resin layer or a nano-silica film layer. Both the acrylic resin layer and the nano-silica film layer can form a dense film layer on the surface of the wooden body 11, have good adhesion to the wooden body 11, and have good hardness and corrosion resistance, enabling the wood product to be more resistant to wear and scratches.
[0052] In some embodiments, the wooden body 11 has a rough structure with a roughness not greater than 2 microns. In this way, it is convenient for subsequent operations (such as sanding), ensures the final appearance of the product, and at the same time can improve the adhesion to the subsequent protective layer and avoid delamination.
[0053] Next, taking the acrylic resin filler 12 as an example of the acrylic resin filler, the manufacturing method of the wood product according to the present application will be described. For other fillers, except that the materials are different from the acrylic resin filler, the other steps can refer to the description of the acrylic resin filler.
[0054] According to the present application, the manufacturing method of the wood product includes selecting wood and sanding the surface of the wood to form a surface structure with a roughness Ra not greater than 2, which is beneficial to the appearance of the final product. At the same time, it can improve the bonding force with the subsequent protective layer and avoid delamination.
[0055] According to the present application, the manufacturing method of the wood product includes immersing the wood product in an immersion liquid so that the immersion liquid enters the surface pores of the wood product, thereby obtaining the wood product according to the present application.
[0056] In some embodiments, the immersion liquid includes an acrylic polymer, a dispersant, a curing agent, and water. The acrylic polymer, as the main substance for forming the acrylic resin, is acid and alkali resistant, waterproof, and has good stability, enabling the wood product to have good waterproofness, hardness, and acid and alkali resistance. The dispersant is used to improve the dispersion of solid particles in the immersion liquid, prevent coalescence, and ensure that the filler is uniform and delicate. The curing agent reacts with the acrylic polymer to reduce the film-forming temperature and enhance the hardness and wear resistance of the acrylic resin. Water is used as a solvent and diluent to adjust the viscosity and fluidity of the immersion liquid, so that the immersion liquid can easily enter the surface pores of the wooden body.
[0057] As an example, based on the total weight of the immersion liquid being 100%, the weight of the acrylic polymer accounts for 20%-30% of the total weight of the immersion liquid, the weight of the dispersant accounts for 2%-6% of the total weight of the immersion liquid, the weight of the curing agent accounts for 2%-3% of the total weight of the immersion liquid, and the balance is water. As an example, the dispersant includes diethylene glycol monoethyl ether and dipropylene glycol methyl ether, and the weight ratio of diethylene glycol monoethyl ether to dipropylene glycol methyl ether can be (1-3):(1-3). The curing agent includes aliphatic polyisocyanate.
[0058] Specifically, the wood product is immersed in the above immersion liquid for 5s-10s, and then dried at 35°C-40°C for 10 hours-14 hours, thereby forming an acrylic resin filler in the surface pores of the wood product.
[0059] By impregnating the wooden body, some hanging bodies of the acrylic resin filler will also appear on the surface of the wooden body. To ensure the surface flatness of the wood product, in some embodiments, after the acrylic resin filler is formed in the surface pores of the wood product, a sanding step is required to increase the surface roughness of the wood product and remove the excess acrylic resin filler particles on the surface of the wood product, thereby providing a better adhesion basis for the subsequent protective layer.
[0060] Specifically, a polishing tool can be used to polish the surface of the dried wood product so that the surface roughness is controlled within a range not greater than 1 micron. Such roughness can ensure that the surface of the wooden main body is flat but not overly smooth. On the one hand, it is beneficial for the setting of the protective layer and can improve the bonding force between the protective layer and the wooden main body. On the other hand, it can ensure the appearance of the product.
[0061] In some embodiments, a waterproof material can be used to form a continuous and uniform protective film (protective layer) on the surface of the wood product to enhance the dishwasher resistance of the coating. As an example, the waterproof material can be the above-mentioned soaking solution, and a continuous and uniform protective film (protective layer) can be formed on the surface of the wood product by air spraying the above-mentioned soaking solution.
[0062] It should be noted that when the waterproof material is the above-mentioned soaking solution, the contents of the components in the waterproof material are the same or different from those in the soaking solution. In a preferred embodiment, the contents of the components in the waterproof material are different from those in the soaking solution, and the fluidity of the waterproof material is relatively lower to facilitate the formation of a protective layer on the surface of the wooden main body.
[0063] Specifically, the wood product is immersed in the above-mentioned soaking solution for 5s - 10s, and then dried at 35°C - 40°C for 10 hours - 14 hours, so as to form a continuous and uniform protective film (protective layer) on the surface of the wood product.
[0064] According to the present application, the wood product prepared by the above process, after testing, has excellent dishwasher resistance. The untreated wood product can only reach 1 test cycle, while the treated wood product can be improved to more than 100 test cycles. Thus, when the wood product is applied to a dishwasher, it can exhibit excellent performance.
[0065] According to the present application, as Figures 2 to 5 shown, the kitchen utensils can be a spatula 100, a rolling pin 200, and a cooking pot 300.
[0066] According to the second aspect of the present application, there is provided a kitchen utensil, wherein the kitchen utensil is made of the above-mentioned wood product, or the kitchen utensil includes a functional part and a handle connected to the functional part, and the handle is made of the above-mentioned wood product.
[0067] In some embodiments, the kitchen utensil is a cooking pot, a spatula, a spoon, a cutting board, or a rolling pin. The wood product can be suitable for various types of kitchen utensils, which can optimize the user experience of using the kitchen utensils.
[0068] As some examples, the kitchen utensil is a spatula, wherein, as Figure 2 and Figure 3As shown in the figure, the shovel tool includes a shovel tool body and the wooden product provided in the above embodiment. The shovel tool body 20 is the above-mentioned functional part, and the wooden product 10 forms the handle of the shovel tool and is connected to the shovel tool body 20.
[0069] As other examples, the kitchen utensil is a cooking pot. Among them, as Figure 5 shown in the figure, the cooking pot includes a cooking pot body and the wooden product provided in the above embodiment. The cooking pot body 30 is the above-mentioned functional part, and the wooden product 10 forms the handle of the cooking pot and is connected to the cooking pot body 30.
[0070] Although the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. However, it should be understood that in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention defined by the claims.
