Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to a steamer. Background Art

[0002] Common electric steamers on the market usually do not have a filtering device, but directly use tap water for heating. Since tap water contains impurities and calcium and magnesium ions, a layer of scale will form in the steamer after long-term use, affecting the heating efficiency. Utility Model Content

[0003] Based on this, it is necessary to provide a steamer that can reduce scale generation.

[0004] A steamer comprises: a pot body, a water tank and a filter assembly, the pot body is provided with a steam generating chamber, the water tank is provided with a water outlet, the water tank is connected with the steam generating chamber through the water outlet, the filter assembly is installed at the water outlet, the filter assembly comprises a cover shell and a filter element, the cover shell is provided with a cavity, the filter element is arranged in the cavity, the side wall of the cover shell is provided with a through hole connected with the cavity, the filter element comprises a first filter layer, a second filter layer and a third filter layer which are arranged in sequence from the outside to the inside, the filter holes of the first filter layer are larger than the filter holes of the second filter layer, the filter holes of the second filter layer are larger than the filter holes of the third filter layer, the third filter layer is a scale inhibitor layer, the third filter layer is provided with a water collecting cavity, and the water collecting cavity is connected with the water outlet.

[0005] The steamer provided in the present application is provided with a filter assembly so that water passes through the filter assembly before entering the steam generating chamber, thereby reducing the generation of scale. Since the filter assembly includes a housing and a filter element, the filter element includes a first filter layer, a second filter layer and a third filter layer arranged in sequence from the outside to the inside, and the third filter layer is a scale inhibitor layer. The first filter layer first filters out large particles to prevent large particles from flowing to the second filter layer and causing blockage, while the second filter layer can filter out smaller particles to prevent the substance from entering the third filter layer. The third filter layer is a scale inhibitor layer, which focuses on scale inhibition and has a better scale inhibition effect. After the water passes through three layers of filtration and is discharged from the water outlet, it has a good filtering effect, thereby effectively reducing scale.

[0006] In one embodiment, the first filter layer is an activated carbon layer, and / or the second filter layer is a fiber layer.

[0007] The activated carbon layer can filter out large particles such as sand, rust, and insect eggs in the water, which can reduce the filtering burden of the second and third filter layers and increase their service life. The fiber layer can further filter viruses, residual chlorine, and other substances to improve the taste of water.

[0008] In one embodiment, the scale inhibitor of the scale inhibitor layer is a malic acid scale inhibitor.

[0009] Malic acid scale inhibitor can form chelates with calcium and magnesium ions in water, thereby preventing calcium and magnesium ions from forming main scale components such as calcium carbonate and magnesium carbonate in the steam generating chamber.

[0010] In one of the embodiments, a first positioning portion and a second positioning portion are respectively provided at the upper and lower ends of the inner side of the housing, and the first positioning portion and the second positioning portion respectively fix the two ends of the filter element.

[0011] In this way, the filter element is easier to install in the cover, and the cover plays a supporting role for the filter element, which can reduce the probability of deformation and damage of the filter element and ensure the effectiveness of the filter element.

[0012] In one embodiment, the first positioning portion extends downward from the inner top wall of the housing, and the upper end of the filter element is sleeved on the outer side of the first positioning portion.

[0013] In this way, the structure of the first positioning portion is very simple. During installation, it is only necessary to cover the upper end of the filter element on the outer side of the first positioning portion, which makes it very easy to install the filter element.

[0014] In one embodiment, the second positioning portion is extended upward from the inner bottom wall of the housing, and the lower end of the filter element is sleeved on the outer side of the second positioning portion.

[0015] In this way, the structure of the second positioning portion is also very simple. During installation, it is only necessary to put the lower end of the filter element on the outer side of the second positioning portion, which makes it very easy to install the filter element.

[0016] In one embodiment, the cover shell includes an upper shell and a lower shell, the upper shell is cylindrical with an opening at the lower end, the lower shell is fixedly connected to the lower end of the upper shell, the first positioning portion is provided on the upper shell, and the second positioning portion is provided on the lower shell.

[0017] In this way, during installation, the filter element can be first installed in the upper shell, and then the lower shell can be installed on the lower end of the upper shell, so that the filter element can be installed in the cover shell. The cover shell is configured as an upper shell and a lower shell, which facilitates the installation of the filter element.

[0018] In one of the embodiments, the cover shell and the water tank are connected via a screw-on structure, or the cover shell and the water tank are threadedly connected.

[0019] In this way, the filter assembly can be easily installed and removed, thereby making it very convenient to replace the filter assembly.

[0020] In one embodiment, there is a gap between the filter element and the side wall of the housing.

[0021] If the filter element is arranged close to the side wall of the housing, the part of the housing side wall where no through hole is arranged will affect the water from entering the filter element, resulting in that the filter element cannot be fully utilized, thereby affecting the filtering effect. In this embodiment, since there is a gap between the filter element and the side wall of the housing, water can first enter the gap between the side wall of the housing and the filter element, and then be filtered by the filter element, so that water can enter the filter element from any position around the filter element, and the filter element can be fully utilized, ensuring the filtering effect of the filter element.

[0022] In one embodiment, the filter element is cylindrical in shape, the outer diameter D of the filter element is 10 mm to 300 mm, and the height H of the filter element is 5 mm to 100 mm.

[0023] In this way, the filter element has different sizes and specifications, and the filter element of different sizes and specifications can be selected according to the size of the water tank to achieve water filtering. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0038] See also Figures 1 to 3 The present application provides a steamer, comprising: a pot body 10, a water tank 20 and a filter assembly 30. The pot body 10 is provided with a steam generating chamber 12, the water tank 20 is provided with a water outlet 21, the water tank 20 is connected with the steam generating chamber 12 through the water outlet 21, and the filter assembly 30 is installed at the water outlet 21. In this way, the water in the water tank 20 flows to the steam generating chamber 12 through the water outlet 21, and is heated in the steam generating chamber 12 to generate steam. It can be understood that the steamer also includes a steamer 40 arranged above the steam generating chamber 12 of the pot body 10, and the steam enters the steamer 40 upward to cook food. The steamer provided by the present application can filter impurities and calcium and magnesium ions in tap water by arranging the filter assembly 30 at the water outlet 21, so that the water reaching the steam generating chamber 12 is very clean water, and it is not easy to generate scale after high temperature heating.

[0039] See also Figures 3 to 5 The filter assembly 30 includes a housing 31 and a filter element 32. The housing 31 is provided with a cavity 311. The filter element 32 is disposed in the cavity 311. The side wall of the housing 31 is provided with a through hole 312 communicating with the cavity 311. In this way, the water in the water tank 20 can enter the housing 31 through the through hole 312, and then be filtered by the filter element 32 and then delivered to the steam generating chamber 12 from the water outlet 21.

[0040] See also Figure 7 The filter element 32 includes a first filter layer 321, a second filter layer 322 and a third filter layer 323 which are arranged in sequence from the outside to the inside. The filter holes of the first filter layer 321 are larger than the filter holes of the second filter layer 322, and the filter holes of the second filter layer 322 are larger than the filter holes of the third filter layer 323. The third filter layer 323 is a scale inhibitor layer. A water collecting chamber 324 is arranged in the third filter layer 323, and the water collecting chamber 324 is connected to the water outlet 21. In this way, the first filter layer 321 first filters out large particles to prevent large particles from flowing into the second filter layer 322 and causing blockage, while the second filter layer 322 can filter out smaller particles to prevent the substances from entering the third filter layer 323. The third filter layer 323 is a scale inhibitor layer, which focuses on scale inhibition and has a better scale inhibition effect. After the water passes through the three layers of filtration and is discharged from the water outlet 21, it has a good filtration effect, thereby being able to effectively reduce scale.

[0041] Furthermore, the first filter layer 321 is an activated carbon layer, which can filter out large particles such as mud, rust, and insect eggs in the water, thereby reducing the filtering burden of the second filter layer 322 and the third filter layer 323 and increasing their service life.

[0042] The second filter layer 322 is a fiber layer. The fiber layer can further filter viruses, residual chlorine and other substances, and improve the taste of water. The second filter layer 322 can be provided with one or more layers. The more layers there are, the slower the water flow rate. In order to achieve a better filtering effect, the water should not flow too fast through the filter element 32, so that the scale inhibitor of the third filter layer 323 can better produce a chelating reaction with the scale. The purpose of controlling the water flow can be achieved by adjusting the number of fiber layers. The fiber layer can be plastic fiber, carbon fiber or biomass fiber (such as bamboo fiber), and this application does not limit this.

[0043] The scale inhibitor of the scale inhibitor layer of this embodiment is a malic acid scale inhibitor, which is made by extracting malic acid from fruit peels. The malic acid scale inhibitor can form chelates with calcium and magnesium ions in water, thereby preventing calcium and magnesium ions from forming calcium carbonate, magnesium carbonate and other main scale components in the steam generating chamber 12. In addition, all materials for the synthetic scale inhibitor are food grade raw materials.

[0044] Furthermore, the filter element 32 has a cylindrical or square shape. Thus, the filter element 32 has a very simple structure and is easy to produce and process.

[0045] In this embodiment, the filter element 32 is cylindrical in shape, the outer diameter D of the filter element 32 is 10 mm to 300 mm, and the height H of the filter element 32 is 5 mm to 100 mm. In this way, the filter element 32 has different sizes and specifications, and filter elements 32 of different sizes and specifications can be selected according to the size of the water tank 20 to achieve water filtering.

[0046] The upper and lower ends of the inner side of the housing 31 are respectively provided with a first positioning portion 313 and a second positioning portion 314, which respectively fix the two ends of the filter element 32. Since the housing 31 is provided with the first positioning portion 313 and the second positioning portion 314, the filter element 32 is more easily installed in the housing 31, and the housing 31 supports the filter element 32, which can reduce the probability of deformation and damage of the filter element 32 and ensure the effectiveness of the filter element 32.

[0047] Furthermore, the first positioning portion 313 extends downward from the top wall of the housing 31, and the upper end of the filter element 32 is sleeved outside the first positioning portion 313. In this way, the structure of the first positioning portion 313 is very simple, and during installation, it is only necessary to sleeve the upper end of the filter element 32 outside the first positioning portion 313, so that the filter element 32 is very easy to install.

[0048] The second positioning portion 314 extends upward from the inner bottom wall of the housing 31, and the lower end of the filter element 32 is sleeved outside the second positioning portion 314. In this way, the structure of the second positioning portion 314 is also very simple. When installing, you only need to sleeve the lower end of the filter element 32 outside the second positioning portion 314, which makes it very easy to install the filter element 32.

[0049] Further, the housing 31 includes an upper housing 315 and a lower housing 316. The upper housing 315 is cylindrical with an opening at the lower end. The lower housing 316 is fixedly connected to the lower end of the upper housing 315. The first positioning portion 313 is provided on the upper housing 315, and the second positioning portion 314 is provided on the lower housing 316. During installation, the filter element 32 can be firstly loaded into the upper housing 315, and then the lower housing 316 is installed on the lower end of the upper housing 315. In this way, the filter element 32 can be installed in the housing 31. The housing 31 is provided with the upper housing 315 and the lower housing 316, which facilitates the installation of the filter element 32. Further, the upper housing 315 and the lower housing 316 can be connected to form a detachable structure by means of a buckle, a thread or the like. In this way, the housing 31 can be reused. When the filter assembly 30 needs to be replaced, only the filter element 32 needs to be replaced. Of course, the upper shell 315 and the lower shell 316 can also be set to a non-detachable structure. For example, the upper shell 315 and the lower shell 316 are fixed by ultrasonic welding, and the cover shell 31 and the filter element 32 are an integral structure, which is more convenient to replace.

[0050] For further information, see Figure 3 and Figure 4 , there is a gap between the filter element 32 and the side wall of the housing 31. If the filter element is set close to the side wall of the housing, the part of the housing side wall where no through hole is set will affect the water entering the filter element from here, resulting in that the filter element cannot be fully utilized, thereby affecting the filtering effect. In this embodiment, since there is a gap between the filter element 32 and the side wall of the housing 31, water can first enter the gap between the side wall of the housing 31 and the filter element 32, and then be filtered by the filter element 32, so that water can enter the filter element 32 from any position around the filter element 32, and the filter element 32 can be fully utilized, ensuring the filtering effect of the filter element 32.

[0051] For further information, see Figure 5 The through holes 312 provided on the cover 31 may be multiple through holes 312 of different sizes, or multiple through holes 312 of the same size. In addition, the shape of the through holes 312 may be various shapes such as circular, square, oval, wavy or heart-shaped, and the present application does not limit this.

[0052] The cover shell 31 may be a cylindrical cover shell 31 , or a square cylindrical cover shell 31 , or a cover shell 31 of other shapes, and the present application does not impose any limitation on this.

[0053] In one embodiment, the housing 31 is connected to the water tank 20 via a screw-on structure, so that the installation and removal of the filter assembly 30 are very convenient. Figure 5 and Figure 6 As shown, the screw-on structure includes a convex buckle 317 disposed on the outer wall of the cover shell 31 and a slot 211 disposed on the inner wall of the water outlet 21. The convex buckle 317 is screwed into the slot 211, thereby installing the cover shell 31 at the water outlet 21 of the water tank 20. In this embodiment, the slot 211 is L-shaped, and the convex buckle 317 is inserted into the slot 211 from top to bottom. Then, the cover shell 31 is rotated to install the cover shell at the water outlet 21 of the water tank 20.

[0054] However, the invention is not limited thereto. In other embodiments, the housing can also be threadedly connected to the water tank. Specifically, the outer wall of the housing is provided with an external thread, and the inner wall of the water outlet of the water tank is provided with an internal thread. Thus, the housing and the water tank are threadedly connected by the cooperation of the external thread and the internal thread. The threaded connection is easy to install and disassemble, and it is very convenient to replace the filter assembly.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
