[0057] A stove according to an embodiment of the present invention is installed on a cabinet countertop 1 and includes:

[0058] Burner 2;

[0059] The housing assembly 3 is located below the cabinet countertop 1 and includes an upper housing 31 and a lower housing 32. The upper housing 31 is detachably connected to the top of the lower housing 32. The upper housing 31 defines a first upper housing through-hole 311. The bottom of the burner 2 is fixed to the lower housing 32, and the top of the burner 2 passes through the first upper housing through-hole 311 to achieve connection between the burner 2 and the housing assembly 3.

[0060] The mounting assembly 4 includes a pre-mounted bracket 41 , wherein one side of the pre-mounted bracket 41 is detachably connected to the housing assembly 3 and the other side is overlapped with the cabinet countertop 1 ;

[0061] The cabinet countertop 1 is provided with a first cabinet countertop through hole 11 for installing the burner 2 , and the pre-installed bracket 41 is installed in the first cabinet countertop through hole 11 for installing the housing assembly 3 on the cabinet countertop 1 from bottom to top.

[0062] Among them, the upper shell 31 is an inverted U-shape, and the lower shell 32 is U-shaped. The upper shell 31 is covered on the lower shell 32 and is connected to the lower shell 32 by bolts, clamping, etc., as long as a detachable connection can be achieved. The shell assembly 3 is located below the cabinet countertop 1. The upper shell 31 is provided with a first upper shell through-hole 311. The bottom of the burner 2 is fixed to the lower shell 32, and the top of the burner 2 passes through the first upper shell through-hole 311 to achieve the connection between the burner 2 and the shell assembly 3. In addition, by installing the pre-installed bracket 41 in the first cabinet countertop through-hole 11, the shell assembly 3 can be conveniently fixed to the cabinet countertop 1 from the bottom of the cabinet countertop, solving the problem of multiple people installing a stove, and facilitating the installation of stove products with a bottom-up structure, so that one person can operate and install it, avoiding waste of human resources.

[0063] In a preferred embodiment of the present invention, the upper housing 31 is provided with an upwardly protruding boss 33 for mounting the burner 2;

[0064] The pre-installed bracket 41 is sleeved on the outer periphery of the boss 33 , wherein the pre-installed bracket 41 is further connected to a buckle 42 , which is detachably connected to the boss 33 ;

[0065] The boss 33 defines a first mounting hole 331 corresponding to the buckle 42 , so that the pre-installed bracket 41 can be rotatably engaged with the boss 33 .

[0066] like Figure 4、 8 As shown in Figure 9, since the shell assembly 3 is located as a whole below the cabinet countertop 1, in order to satisfy one staff member, the shell assembly 3 and the cabinet countertop 1 can be aligned and installed. In this embodiment, a pre-installed bracket 41 and a clip 42 are used. First, the clip 42 is inserted into the first installation hole 331 and rotated and then snapped into the boss 33 to achieve the fixation of the inner periphery of the pre-installed bracket 41 and the boss 33. At the same time, the outer periphery of the pre-installed bracket 41 is overlapped with the cabinet countertop 1, thereby achieving the connection and pre-fixation of the shell assembly 3 and the cabinet countertop 1. The structure is simple and only one person is required to achieve installation.

[0067] In this embodiment, the boss 33 is formed by integral stretching through a mold. To facilitate processing, the draft angle is designed to be 10°~45°, the stretching depth is between 5mm~25mm, and the straight edge is provided with a rounded chamfer R=2~10 times the material thickness for easy stretching. The first upper shell through hole 311 is provided on the top surface of the boss 33 to facilitate the extension of the burner 2.

[0068] In a preferred embodiment of the present invention, the pre-installed bracket 41 comprises:

[0069] annular groove 411;

[0070] The first flange 412 is provided on the top periphery of the annular groove 411 and overlaps the cabinet countertop 1;

[0071] The second flange 413 is provided on the inner periphery of the top of the annular groove 411 and overlaps the top of the boss 33;

[0072] The annular groove 411 is inserted between the first cabinet countertop through hole 11 and the boss 33 , so that the boss 33 and the first cabinet countertop through hole 11 are installed in an aligned manner.

[0073] like Figure 3-4 As shown in Figures 8-9, the outer diameter of the first cabinet countertop through hole 11 is much larger than the outer diameter of the boss 33. The annular groove 411 is inserted between the first cabinet countertop through hole 11 and the boss 33, so that the boss 33 and the first cabinet countertop through hole 11 can be quickly aligned and installed, thereby improving installation efficiency.

[0074] In a preferred embodiment of the present invention, the inner periphery of the second flange 413 is connected to the buckle 42, the first mounting hole 331 is located on the top surface of the boss 33, the first mounting hole 331 includes a first arc-shaped hole segment 3311 and a second arc-shaped hole segment 3312 connected to the first arc-shaped hole segment 3311, the width of the first arc-shaped hole segment 3311 is greater than the width of the second arc-shaped hole segment 3312, so that after the buckle 42 is inserted into the first arc-shaped hole segment 3311, it is clamped to the second arc-shaped hole segment 3312.

[0075] like Figure 1-7As shown, the buckle 42 is L-shaped, comprising a horizontal section and a vertical section perpendicular to the horizontal section. The upper portion of the vertical section is fixed to the second flange 413. In this embodiment, the length and width of the first arcuate hole section 3311 are both greater than those of the horizontal section, while the width of the second arcuate hole section 3312 is less than that of the horizontal section. This allows the horizontal section to be inserted into the first arcuate hole section 3311. By rotating the buckle 42, the vertical portion of the buckle 42 snaps into the second arcuate hole section 3312, achieving a rotational engagement between the buckle 42 and the first mounting hole 331, facilitating the installer's pre-fixing of the cooktop. Furthermore, a transition section is provided between the first arcuate hole section 3311 and the second arcuate hole section 3312 to facilitate the buckle 42's smooth transition from the first arcuate hole section 3311 to the second arcuate hole section 3312.

[0076] In a preferred embodiment of the present invention, a sealing ring 43 is provided between the first flange 412 and the first cabinet countertop through hole 11, the top of the sealing ring 43 is provided with an annular rib 431, and the bottom of the first flange 412 is provided with a first flange groove corresponding to the annular rib 431 to limit the pre-installed bracket 41.

[0077] like Figure 4 As shown, the sealing ring 43 is located between the first flange 412 and the first cabinet countertop through-hole 11. On the one hand, the sealing ring 43 can compensate for the height difference between the boss 33 and the cabinet countertop 1, making the installation of the pre-installed bracket 41 more stable. On the other hand, by providing an annular rib 431 on the sealing ring 43 and providing a first flange groove at the bottom of the first flange 412, the pre-installed bracket 41 can be prevented from moving and the installation position of the pre-installed bracket 41 can be limited. The installation position of the pre-installed bracket 41 can be used to center the boss 33, thereby improving installation efficiency. The sealing ring 43 and the cabinet countertop 1 can be bonded with glue, or a silicone ring can be used, which is placed on the through-hole 11 of the first cabinet countertop.

[0078] In a preferred embodiment of the present invention, the cooker further comprises:

[0079] The liquid collecting pan 5 is provided above the pre-installed bracket 41 and the boss 33 to prevent external liquid from entering the interior of the cooker.

[0080] like Figure 4 As shown, after the clip 42 is inserted into the first mounting hole 331, there is still a large gap between it and the first mounting hole 331. By covering the liquid collecting pan 5 on the second flange 413 and the boss 33, the liquid collecting pan 5 and the top of the boss 33 are in contact with each other, which can prevent external liquid from entering the interior of the stove from the first mounting hole 331.

[0081] In a preferred embodiment of the present invention, the liquid collecting pan 5 is a truncated cone-shaped thin-walled structure, comprising a horizontal portion 51 and an inclined portion 52, wherein one end of the inclined portion 52 is fixedly connected to the horizontal portion 51, and a liquid collecting pan through hole 511 for the burner 2 to pass through is provided in the middle of the horizontal portion 51, and the outer periphery of the horizontal portion 51 is detachably connected to the boss 33.

[0082] The liquid receiving tray 5 also includes:

[0083] One end of the vertical portion 53 is clamped to the outer periphery of the pre-installed bracket 41 , and the other end is fixed to the other end of the inclined portion 52 .

[0084] The width of the horizontal portion 51 is 20 mm to 30 mm, and the angle between the inclined portion 52 and the horizontal plane is a, where 1°≤a≤15°, and is used to guide the external liquid;

[0085] The height of the inclined portion 52 is h, where 1 mm ≤ h ≤ 10 mm.

[0086] like Figure 10-11 As shown, the liquid collecting pan 5 is a truncated cone-shaped thin-walled structure, including a horizontal portion 51, an inclined portion 52 and a vertical portion 53, wherein a liquid collecting pan through hole 511 for the burner to pass through is provided in the middle of the horizontal portion 51, and the inner diameter of the vertical portion 52 corresponds to the outer diameter of the pre-installed bracket 41, so that the vertical portion 52 is stuck on the outer periphery of the pre-installed bracket 41 to provide support for the liquid collecting pan 5. At the same time, the vertical portion 52 can block the sealing ring 43 inside the liquid collecting pan 5, because the sealing ring 43 is generally made of plastic or other materials, it is corroded by external liquid for a long time and is easily deformed, and the vertical portion 52 can protect the sealing ring 43, making it easier to clean and improving the product life.

[0087] Furthermore, the height of the inclined portion 52 is h, where 1 mm ≤ h ≤ 10 mm, and preferably 1 mm ≤ h ≤ 5 mm. Within this height range, there is no need to adjust the pot support height or the burner 2 installation height. Furthermore, during combustion, the flame is kept away from the liquid pan 5, preventing the liquid pan 5 from being exposed to high temperatures for extended periods and thus deforming. In this example, the height of the inclined portion 52, i.e., the distance between the highest point of the inclined portion 52 and the top surface of the vertical portion 53, and thus the distance between the horizontal portion 51 and the top surface of the vertical portion 53, corresponds to the height difference between the top surface of the liquid pan 5 and the boss 33.

[0088] The width of the horizontal portion 51 is 20 mm to 30 mm, and the angle between the inclined portion 52 and the horizontal plane is a, wherein 1°≤a≤15°, preferably 5°≤a≤10°. At this time, most of the overflowing liquid on the cooker falls on the inclined portion 52, which can guide the liquid to avoid entering the interior of the cooker and protect the products inside the cooker. Figure 10 The horizontal portion shown is an annular structure, and the width of the horizontal portion 51 is the difference between the inner diameter and the outer diameter of the horizontal portion 51 .

[0089] In a preferred embodiment of the present invention, a second mounting hole 332 is provided at the top of the boss 33, and a liquid pan threaded hole 512 corresponding to the second mounting hole 332 is provided on the horizontal portion 51. The liquid pan threaded hole 512 is bolted to the second mounting hole 332, and a gasket is provided between the liquid pan threaded hole 512 and the second mounting hole 332. The thickness of the gasket is greater than the thickness of the second flange 413.

[0090] like Figure 4 、 8 As shown, a plurality of second mounting holes 332 are provided on the top of the boss 33 , preferably 3-4, wherein the number of the liquid pan threaded holes 512 on the liquid pan 5 and the second mounting holes 332 are the same and correspond one to one, so as to fix the liquid pan 5 to the boss 33 .

[0091] At the same time, the gasket can stably fix the liquid pan 5 on the boss 33. Especially when the liquid pan 5 includes a horizontal portion 51 and an inclined portion 52, the height difference between the thickness of the gasket and the thickness of the second flange 413 determines the relative height of the liquid pan 5 and the boss. When the height difference is 1~5mm, it can prevent the liquid pan 5 from being too close to the burner head, thereby preventing high-temperature deformation.

[0092] In addition, there is a certain angle between the inclined portion 52 and the horizontal plane or the cabinet countertop 1, preferably in the range of 5° to 10°, so as to prevent external liquid from entering the stove.

[0093] In a preferred embodiment of the present invention, a second mounting hole 332 is provided at the top of the boss 33, and a mounting block corresponding to the second mounting hole 332 is provided on the horizontal portion 51. The mounting block is inserted into the second mounting hole 332 for connecting the liquid tray 5 and the boss 33.

[0094] The mounting block is T-shaped and includes:

[0095] A first supporting portion, one end of which is connected to the liquid receiving tray 5 and the outer periphery of the other end of which abuts against the boss 33;

[0096] The second support portion is located below the first support portion, fixed to the middle portion of the other end of the first support portion, and extends downward to be inserted into the second mounting hole 332. The second support portion is loosely fitted in the second mounting hole 332.

[0097] The height of the first supporting portion is greater than the thickness of the second flange 413 .

[0098] like Figure 4 、 8As shown, the top of the boss 33 is provided with a plurality of second mounting holes 332, preferably 3-4, wherein the number of the mounting blocks and the second mounting holes 332 is the same and corresponds one to one. By inserting the mounting blocks into the second mounting holes 332, the liquid tray 5 is fixed to the boss 33, which has a simple structure and is easy to install.

[0099] In addition, the mounting block is T-shaped, wherein the second support portion is loosely fitted with the second mounting hole 332 and inserted into the second mounting hole 332, and the bottom periphery of the first support portion abuts against the boss 33. The mounting block can stably fix the liquid pan 5 to the boss 33. Preferably, the height difference between the height of the first support portion and the thickness of the second flange 413 is 1~5mm, so as to avoid the liquid pan 5 being too close to the burner and thus causing high-temperature deformation. There is a certain angle between the inclined portion 52 and the horizontal plane or the cabinet countertop 1, and the preferred angle range is 5°~10° to prevent external liquid from entering the interior of the stove.

[0100] In a preferred embodiment of the present invention, a plug valve 6 is further included, and the plug valve 6 includes:

[0101] The valve body 61 is located below the upper housing 31;

[0102] A valve core is provided inside the valve body 61;

[0103] The valve cover 62 is provided on the valve body 61 , wherein the valve cover 62 includes a cylindrical body 621 , a valve cover through hole 623 is provided on the side of the cylindrical body 621 away from the valve body 61 , and a frustum 622 is provided on the side of the cylindrical body 621 close to the valve body 61 for connecting with the valve body 61 ;

[0104] The valve stem 63 is connected to the valve core and extends outward to pass through the valve cover through hole 623;

[0105] Among them, the upper shell 31 is also provided with a second upper shell through hole, and the cabinet countertop 1 is also provided with a second cabinet countertop through hole. The second cabinet countertop through hole is installed with a sleeve 7, and the cylinder 621 passes through the upper second shell through hole and is inserted into the sleeve 7. The outer periphery of the cylinder 621 is provided with an external thread, and the sleeve 7 is provided with an internal thread corresponding to the cylinder 621 to install the valve cover 62 on the cabinet countertop 1.

[0106] like Figure 5-7 As shown, an annular plate for connecting to the cabinet countertop 1 is provided on the upper periphery of the sleeve 7, and the annular plate abuts against the top surface of the cabinet countertop 1. Preferably, a sealing ring is provided between the annular plate and the cabinet countertop 1 to prevent external liquid from entering the stove through the gap between the annular plate and the cabinet countertop 1.

[0107] The valve body 61 is located in the cavity formed by the upper shell 31 and the lower shell 32. The round table 622 on the valve cover 62 is bolted to the valve body 61. The cylinder 621 moves from bottom to top, first passes through the through hole of the second upper shell and then inserts into the through hole of the second cabinet countertop, and is threadedly connected to the sleeve 7, thereby realizing the installation and fixation of the plug valve 6 and the cabinet countertop 1. The structure is simple and the operation is convenient, and the plug valve 6 can be aligned and installed from bottom to top.

[0108] In this embodiment, the top of the cylinder 621 is 5 to 20 mm above the top of the upper housing 31, ensuring a certain contact area with the sleeve 7 and improving structural stability.
