Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a quick steamer. Background Art

[0002] As people pay more attention to healthy eating, steamers have become popular because they can preserve the nutrients and original flavor of ingredients. They are widely used in home kitchens, catering industry, and healthy catering.

[0003] A steamer heats the food above by heating the liquid at the bottom, causing it to evaporate and produce steam. Therefore, a steamer doesn't begin heating food immediately; it must first bring the liquid at the bottom of the steamer to a boil before heating the food. To ensure immediate heating without adding additional liquid, the steamer needs to contain a sufficient amount of liquid. However, a steamer needs to bring the entire liquid to a boiling point before it can begin heating the food. Heating a large amount of liquid at once results in a long wait between starting the steamer and when it begins heating the food, affecting the food's heating efficiency.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a fast steamer to improve the heating efficiency of the steamer.

[0006] The technical solution of the utility model is as follows:

[0007] A quick steamer comprises: a pot body; a water tank, arranged below the pot body, with a through hole provided on the bottom surface of the water tank; a water retaining rib extending upward from the bottom surface of the water tank around the through hole, with a water inlet provided on the water retaining rib; an air collecting hood, covering the water retaining rib, with an air outlet provided on the upper portion of the air collecting hood, the air outlet being connected to the pot body; a heating element, located at the lower portion of the air collecting hood; wherein the heating element is arranged at the through hole; a sealing ring is provided between the air collecting hood and the water retaining rib, the sealing ring being clamped to the air collecting hood; the air collecting hood, the water retaining rib and the heating element are surrounded to form a heating chamber; the water inlet is respectively connected to the water tank and the heating chamber.

[0008] A further technical solution is that the air collecting hood includes a first sealing rib arranged circumferentially, a groove is provided on the sealing ring, and the first sealing rib is inserted into the groove.

[0009] A further technical solution is that a second sealing rib is circumferentially provided on the sealing ring, and the second sealing rib contacts the water retaining rib.

[0010] A further technical solution is that the second sealing rib is a trapezoidal sealing rib.

[0011] A further technical solution is that a blind hole is opened on a side of the sealing ring close to the water retaining rib, and the blind hole is arranged perpendicular to the water retaining rib.

[0012] A further technical solution is that a heat insulating portion is provided on the lower portion of the gas collecting hood and extends circumferentially upward; the heat insulating portion, the surface of the gas collecting hood and the lower surface of the pot body surround and form a heat insulating cavity.

[0013] A further technical solution is that the air collecting hood further includes an extension portion extending downward, and when the air collecting hood is covered on the water retaining rib, the extension portion extends into the annular water retaining rib.

[0014] A further technical solution is that the aperture of the gas collecting hood decreases along the rising direction of the steam, and the aperture of the gas outlet is smaller than the aperture of the through hole.

[0015] A further technical solution is that the bottom surface of the water tank has a downward inclined section from its outer edge to the through hole.

[0016] The beneficial technical effects of the present utility model are as follows:

[0017] (1) The rapid steamer in the present invention is provided with an air collecting hood in the water tank. The air collecting hood cover is provided on the water retaining rib and is sealed and connected. A heating element is also provided below the air collecting hood, so that the air collecting hood, the water retaining rib and the heating element surround and form a heating chamber. At the same time, a water inlet is provided on the water retaining rib to connect the water tank and the heating chamber. When liquid is added to the water tank, the liquid in the water tank will flow into the heating chamber. When the rapid steamer is started, the heating element directly heats the liquid in the heating chamber. Because the air collecting hood and the water retaining rib isolate the heating chamber and the water tank, there is less exchange between the liquid in the heating chamber and the liquid in the water tank, and most of the heat of the heating element acts on the liquid in the heating chamber, heating the liquid in the heating chamber to the boiling point to generate steam to heat the food. In this way, the liquid in the heating chamber is far less than the liquid in the water tank, and less heat is required to heat the small amount of liquid in the heating chamber to the boiling point, and the speed of generating steam is also faster, which reduces the waiting period from starting the steamer to the steamer starting to heat the food, thereby improving the heating efficiency of the steamer.

[0018] (2) Furthermore, a sealing ring is provided between the air collecting hood and the water retaining rib, and the sealing ring ensures the sealing performance between the air collecting hood and the water retaining rib, thereby reducing the mutual flow of the liquid in the heating chamber and the liquid in the water tank, thereby reducing the heat transfer efficiency between the heating chamber and the water tank, and quickly allowing the liquid in the heating chamber to generate steam, thereby increasing the steam generation speed.

[0019] (3) Furthermore, a heat-insulating cavity is provided on the surface of the gas collecting hood, and the heat-insulating cavity further reduces the efficiency of heat transfer between the heating cavity and the water tank, so as to increase the speed at which the liquid in the heating cavity is heated to generate steam.

[0027] Figure 1 The schematic diagram of the structure of the quick steamer of the present invention in the main viewing direction is shown. Figure 2The schematic diagram of the structure of the quick steamer of the present invention after the pot body 1 is hidden is shown. Figure 1 and Figure 2 A quick steamer comprises a pot body 1, a water tank 2, an air collecting hood 3 and a heating element 5. The water tank 2 is arranged below the pot body 1, and a through hole 23 is provided on the bottom surface of the water tank 2. Surrounding the through hole 23, a water retaining rib 21 is extended upward from the bottom surface of the water tank 2, and a water inlet 22 is provided on the water retaining rib 21. The air collecting hood 3 is covered on the water retaining rib 21, and an air outlet 32 is provided on the upper part of the air collecting hood 3, and the air outlet 32 is connected to the pot body 1. The heating element 5 is located at the lower part of the air collecting hood 3. Among them, the heating element 5 is arranged at the through hole 23. A sealing ring 4 is provided between the air collecting hood 3 and the water retaining rib 21, and the sealing ring is clamped to the air collecting hood 3. The sealing performance between the air collecting hood 3 and the water retaining rib 21 is ensured by the sealing ring 4, which reduces the mutual flow between the liquid in the heating chamber 36 and the liquid in the water tank 2, thereby reducing the heat transfer efficiency between the heating chamber 36 and the water tank 2, quickly allowing the liquid in the heating chamber 36 to generate steam, and increasing the steam generation rate. The air collecting hood 3, the water retaining rib 21 and the heating element 5 surround and form the heating chamber 36. The water inlet 22 is connected to the water tank 2 and the heating chamber 36 respectively. When liquid is added to the water tank 2, the liquid in the water tank 2 will flow into the heating chamber 36. When the quick steamer is started, the heating element 5 directly heats the liquid in the heating chamber 36. Because the air collecting hood 3 and the water retaining rib 21 isolate the heating chamber 36 and the water tank 2, there is less exchange between the liquid in the heating chamber 36 and the liquid in the water tank 2, and most of the heat of the heating element 5 acts on the liquid in the heating chamber 36, heating the liquid in the heating chamber 36 to boiling point to generate steam to heat the food. In this way, the liquid in the heating chamber 36 is far less than the liquid in the water tank 2. Less heat is required to heat the small amount of liquid in the heating chamber 36 to boiling point, and the speed of generating steam is faster, which reduces the waiting period from starting the steamer to the steamer starting to heat the ingredients, thereby improving the heating efficiency of the steamer.

[0028] The specific structure of the seal between the gas collecting cover 3 and the water retaining rib 21 is described below:

[0029] Figure 3 It shows a partial enlarged view of the quick steamer of the present invention at point A. Please refer to Figure 2 and Figure 3 The gas collecting hood 3 includes a first sealing rib 31 arranged circumferentially, and a groove 41 is opened on the sealing ring 4. The first sealing rib 31 is inserted into the groove 41 to fix the sealing ring 4 on the gas collecting hood 3, thereby increasing the stability of the connection between the sealing ring 4 and the gas collecting hood 3.

[0030] Furthermore, a second sealing rib 42 is circumferentially arranged on the sealing ring 4, and the second sealing rib 42 contacts the water retaining rib 21, and a side seal is formed between the second sealing rib 42 and the water retaining rib 21. The second sealing rib 42 is a trapezoidal sealing rib, that is, the outer side surface of the second sealing rib 42 is inclined. When in use, the inclined surface of the second sealing rib 42 has a larger surface area than the vertical plane. When the second sealing rib 42 is completely in contact with the water retaining rib 21, a larger contact surface can be formed between the second sealing rib 42 and the water retaining rib 21, thereby achieving an effective and reliable seal. In addition, the volume of the inclined surface in the vertical direction is smaller, and when the inclined surface is squeezed laterally, the deformation range of the inclined surface is larger, which can partially compensate for the assembly error between the sealing rib and the water retaining rib 21. Therefore, the assembly accuracy requirements for the sealing rib and the water retaining rib 21 are relatively low, which facilitates the assembly and maintenance of the sealing rib and the water retaining rib 21.

[0031] Furthermore, a blind hole 43 is provided on the side of the sealing ring 4 near the water retaining rib 21. Blind hole 43 is arranged perpendicular to the water retaining rib 21. Blind hole 43 helps release pressure from the sealing ring 4, preventing damage, failure, or significant deformation of the sealing ring 4 due to excessive pressure. Blind hole 43 also enhances the flexibility and deformation capacity of the sealing ring 4, making it easier to align and install the sealing ring 4 when space is limited.

[0032] The specific structure of the air collecting hood 3 and the water tank 2 is described below:

[0033] Please refer to Figure 1 and Figure 2 An insulating portion 33 extends circumferentially upward from the lower portion of the gas collecting hood 3. The insulating portion 33, the surface of the gas collecting hood 3, and the lower surface of the pot body 1 form an insulating cavity 34. This cavity 34 further reduces the efficiency of heat transfer between the heating cavity 36 and the water tank 2, thereby increasing the rate at which the liquid in the heating cavity 36 is heated to generate steam.

[0034] In this embodiment, the lower portion of the air hood 3 also includes an extension portion 35 extending downward. When the air hood 3 is placed on the water retaining rib 21, the extension portion 35 extends into the annular water retaining rib 21. Correspondingly, the first sealing rib 31 is arranged horizontally on the extension portion 35. At this time, the second sealing rib 42 on the sealing ring 4 is also arranged horizontally, and the lower portion of the air hood 3 and the upper portion of the water retaining rib 21 are plugged into each other. With this arrangement, the air hood 3 can be quickly installed on the water retaining rib 21 by moving it in the vertical direction, or the air hood 3 and the water retaining rib 21 can be separated, allowing the rapid steamer to switch between centralized heating and ordinary heating.

[0035] Furthermore, the aperture of the gas collecting hood 3 decreases as the steam rises, and the aperture of the gas outlet 32 is smaller than that of the through hole 23, thereby concentrating the discharge of steam from the gas collecting hood 3. The small aperture of the gas outlet 32 limits the maximum steam discharge rate, reducing the fluctuation of the steam discharge rate during the process of steam generation and cessation, and ensuring that steam enters the pot body 1 more evenly and stably.

[0036] The bottom surface of the water tank 2 is a downward inclined section from its outer edge to the through hole 23, which facilitates the liquid in the water tank 2 to automatically flow into the heating chamber 36 and avoids incomplete evaporation of the liquid in the water tank 2 and residual liquid.

[0037] The specific workflow of this utility model is as follows:

[0038] Without the gas hood 3 installed, the liquid in the water tank 2 can flow freely. When the power is turned on, the heating element 5 heats the liquid above it. Through convection and heat transfer within the water tank 2, the heat generated by the heating element 5 acts on the entire liquid in the water tank 2 until the food in the pot 1 is fully heated or the liquid in the water tank 2 evaporates. During this process, the entire liquid in the water tank 2 is heated to the boiling point, generating steam, which rises and heats the food.

[0039] When the steam generation speed needs to be increased, the air collecting hood 3 is first installed in the water tank 2. The lower part of the air collecting hood 3 and the water retaining rib 21 are plugged and sealed to form a heating chamber 36. The air collecting hood 3 and the water retaining rib 21 work together to limit the exchange of liquid between the heating chamber 36 and the water tank 2. Liquid is added to the water tank 2, and the liquid in the water tank 2 flows into the heating chamber 36 along the water inlet 22. The power is turned on to the heating element 5, and the heat of the heating element 5 acts on the liquid in the heating chamber 36. A small amount of the heat of the liquid in the heating chamber 36 is transferred to the liquid in the water tank 2 until the food in the pot body 1 is heated or the liquid in the water tank 2 is completely evaporated. In this process, the liquid in the heating chamber 36 is quickly heated to the boiling point to generate steam, and the steam rises to heat the food.

[0040] It can be seen that the above-mentioned rapid steamer is provided with an air collecting hood 3, so that most of the heat of the heating element 5 ultimately acts on the liquid in the heating chamber 36. The liquid in the heating chamber 36 is far less than the liquid in the water tank 2. Less heat is required to heat the liquid in the heating chamber 36 to the boiling point, and the speed of generating steam is also faster, which reduces the waiting period from starting the steamer to the time when the steamer starts heating the ingredients, thereby improving the heating efficiency of the steamer.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0042] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
