Description

Technical Field

[0001] The present invention relates to the technical field of cooking devices, in particular to a steam boiler and a steam boiler component. Background Art

[0002] When cooking by condensation, a steam pot is usually used as a container. For example, the classic Yunnan dish "steam pot chicken" is cooked by putting chicken and other ingredients into a steam pot. Most traditional steam pots have a fixed steam pipe extending from the bottom of the pot to the inside of the pot body. The upper end of the steam pipe is located at the upper part of the pot body. The steam pipe collects the steam at the bottom of the pot body and guides it into the upper part of the pot for condensation cooking.

[0003] However, the existing steam pipe and the pot body are integrally formed, and the steam pipe itself cannot be moved, resulting in a complex internal structure of the steamer, a small space, and high requirements on the size of the food. In addition, when in use, the steamer must be placed in a steamer, and the steamer provides steam to the steamer. Therefore, the traditional steamer has a single function and is complicated to operate. In addition, although the existing ordinary soup pot and other containers have a large internal space, they are not conducive to the collection and condensation of steam, resulting in energy waste.

[0075] The pot cover 102 can move within the end surface of the open end of the pot body 101, so as to adjust the distance between the edge of the first notch 103 and the edge of the second notch 104, so as to adjust the size of the steam nozzle opening. Specifically, when in use, the pot cover 102 is moved so that the second notch 104 is radially away from the first notch 103, so that the aperture of the steam nozzle opening is larger than the outer diameter of the steam nozzle pipe, so that the steam nozzle pipe can be conveniently and quickly inserted into the steam nozzle opening. After insertion, the pot cover 102 is moved in the opposite direction so that the second notch 104 is radially close to the first notch 103, so that the edges of the first notch 103 and the second notch 104 can be fully or partially fitted with the outer wall of the steam nozzle pipe, so as to reduce steam escape and save energy.

[0076] In addition, when it is necessary to add food to the pot or stir the food in the pot, the pot cover 102 can be easily opened directly, and the operation process is very convenient and smooth.

[0077] In some embodiments, the number of the first notch 103 and the number of the second notch 104 may be one each.

[0080] In certain embodiments, see Figure 3 As shown, the tea maker also includes a tea maker, which is located below the pot cover 102 and includes a tea strainer 105 and a water suction pipe 106; the tea strainer 105 is provided with a through hole for the water suction pipe 106 to pass through, the steam nozzle pipe can extend into the bottom of the water suction pipe 106, the outer tube wall of the water suction pipe 106 is connected to the tea strainer 105, and the lower half of the water suction pipe 106 is provided with a necked throat 108, and the necked throat 108 is provided with a water suction hole 107.

[0081] Specifically, the diameter of the water suction pipe 106 is larger than the outer diameter of the steam nozzle pipe; the water suction pipe 106 passes through the bottom surface of the tea strainer 105 and is fixedly connected to the tea strainer 105. The length of the upper section of the water suction pipe 106 located above the bottom surface of the tea strainer 105 is equivalent to the depth of the tea strainer 105, and the lower end of the water suction pipe 106 reaches the bottom of the pot body 101; the lower half of the water suction pipe 106 is provided with a necked throat 108, and the necked throat 108 is close to the lower end of the water suction pipe 106. Water suction holes 107 are opened radially at the necked throat 108. The number of the water suction holes 107 is 1 to 16, and water is pumped by using the throat principle.

Due to the negative pressure principle of the throat, the water in the pot is sucked in from the water suction hole 107 for mixing and heating, and then sprayed out from the upper end of the water suction pipe 106, sprayed onto the inner wall of the pot cover 102, and then splashed onto the tea leaves in the tea strainer 105, so as to soak and heat the tea leaves, and the formed tea soup drips into the water in the pot body 101 to form tea water.

[0083] By providing the tea maker, the steam boiler can be used to make tea, thus enriching the function of the steam boiler and the user does not need to purchase a tea maker separately.

For details, see Fig.14 and Fig.15 As shown, when the steam nozzle opening is a circular hole 109 and is located on the pot cover 102 or the pot body 101, the enclosure 120 is located around the steam nozzle opening. Fig.15 As shown, when the round hole 109 is located on the pot body 101, the opening of the enclosure can be set obliquely upward. Fig.16 As shown, when the edge of the pot cover 102 is stuck on the inner wall of the pot body 101, the enclosure 120 is located around the pot mouth, that is, the enclosure 120 can be an annular baffle extending upward along the pot wall. Fig.17 As shown, when the area of ​​the pot cover 102 is larger than the pot mouth, the enclosure 120 can be set on the outer wall of the pot body 101, and the enclosure 120 can form an annular groove with the outer wall of the pot body 101, and the edge of the pot cover 102 is located in the annular groove.

[0120] Embodiment 8

[0121] This embodiment provides a boiler assembly, including a steam nozzle pipe, a steam generator 117 and a steam boiler provided in Embodiment 2 of the present invention; one end of the steam nozzle pipe is connected to the steam generator 117, and the other end of the steam nozzle pipe is connected to the steam nozzle orifice.

[0122] The boiler assembly provided in this embodiment uses the steam boiler provided in the second embodiment of the present invention. By adjusting the size of the steam nozzle orifice, it is not only easy to insert and remove the steam nozzle pipe, but also when the steam nozzle pipe is inserted into the steam boiler, the size of the steam nozzle orifice is reduced, so that the gap between the edge of the steam nozzle orifice and the outer wall of the steam nozzle pipe is reduced, which is beneficial to the collection and condensation of steam, prevents steam from escaping, and avoids energy waste.

[0123] Further, in certain embodiments, see Fig.18 As shown, the steam nozzle pipeline includes a steam delivery pipe 118 and a steam nozzle 119; one end of the steam delivery pipe 118 is used to communicate with the steam generator 117, and the other end of the steam delivery pipe 118 is connected to the steam nozzle 119; the end of the steam delivery pipe 118 connected to the steam nozzle 119 can move relative to the steam boiler, so that the steam nozzle 119 enters the set position in the steam boiler or moves out of the steam boiler through the steam nozzle orifice on the steam boiler; the steam nozzle 119 is used to deliver steam, and the steam nozzle 119 can be fixed at any position or multiple positions on its moving path. Among them, the set position refers to the position where the user places the steam nozzle 119 in the steam boiler according to actual cooking needs; the steam nozzle 119 is used to deliver steam, and the steam nozzle 119 can be fixed at any position or multiple positions on its moving path, that is, the steam nozzle 119 can move continuously on its moving path and stay at any position, or the steam nozzle 119 can move a certain distance each time and stay, that is, the multiple position points where the steam nozzle 119 stays on its moving path are discrete.

[0124] Since the spring piece 110 can be deformed, when the steam nozzle 119 is located in the pot, the food in the pot can be stirred or stir-fried by shaking the steam nozzle 119 .

[0125] It should be noted that the boilers in embodiments 1, 3 to 7 are also applicable to the boiler assembly provided in this embodiment.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
