Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a stove head and a burner. Background Art

[0002] Burners are devices widely used in home kitchens. Burners usually have burners, and burners mostly include a burner base, a flame distribution plate, a liquid collection plate and a thermocouple. The thermocouple passes through the burner base, the flame distribution plate and the liquid collection plate in sequence. Fasteners such as screws are used to connect the thermocouple to the burner base, which requires more fasteners and other materials, increases costs, and requires time to connect the fasteners, resulting in low production efficiency. In addition, the fasteners often protrude from the outside of the burner base, so that the screw heads and nuts are exposed at the burner base, which can easily cause injuries to the hands of cleaners during cleaning. Utility Model Content

[0003] In order to at least partially solve the problems existing in the prior art, the utility model provides a stove head, and the technical solution is as follows.

[0004] The furnace head includes a furnace base with a mounting bottom wall, and a thermocouple penetration hole penetrates the mounting bottom wall. The thermocouple penetration hole includes a first hole, a second hole and a first connecting groove. The first hole is connected to the second hole through the first connecting groove, and the diameter of the first hole is greater than the diameter of the second hole.

[0005] The burner head provided by the utility model has a thermocouple insertion hole passing through the installation bottom wall, and the thermocouple insertion hole includes a first hole, a second hole and a first connecting groove. When applied to the burner, the thermocouple can first pass through the first hole from bottom to top and then move to the second hole, so that the thermocouple is connected to the installation bottom wall without the need for fasteners. On the one hand, the cost of the fasteners can be reduced. On the other hand, there is no need to spend time connecting the fasteners, which improves production efficiency and avoids the problem of injuries to the hands of cleaning personnel due to exposed fasteners.

[0006] Exemplarily, the first connecting groove has a first width in a first direction, the first width is smaller than the diameter of the second hole, and the first direction is perpendicular to a line connecting the center of the first hole and the center of the second hole. In this way, when applied to a burner, the thermocouple can be confined in the second hole, so that the thermocouple cannot move outside the second hole through the first connecting groove.

[0007] Exemplarily, the installation bottom wall has a bottom surface and a top surface that are arranged opposite to each other, and the top surface is provided with a first connecting column extending from the periphery of the second hole in a direction away from the bottom surface. In this way, when applied to the burner, the thermocouple contacts the first connecting column when passing through the second hole, the contact area between the thermocouple and the installation bottom wall is increased, and the first connecting column limits the thermocouple in the horizontal direction, which can increase the stability of the connection between the thermocouple and the burner head.

[0008] Exemplarily, the installation bottom wall has an inner ring and an outer ring, the stove base also has an inner side wall and an outer side wall, the inner side wall is connected to the inner ring, the outer side wall is connected to the outer ring, and the height of the first connecting column relative to the top surface is not greater than the height of the inner side wall or the outer side wall relative to the top surface. In this way, when applied to a burner, when a device such as a flame distribution plate needs to be connected to the stove head, the height of the first connecting column is not greater than the height of the inner side wall or the outer side wall, and when the flame distribution plate cover is arranged on the outer side wall of the stove head, the first connecting column will not affect the connection between the flame distribution plate and the outer side wall of the stove head.

[0009] Exemplarily, the bottom surface is formed with a second connecting column extending from the periphery of the second hole in a direction away from the top surface. Thus, when applied to the burner, the thermocouple contacts the second connecting column when passing through the second hole, the contact area between the thermocouple and the installation bottom wall is increased, and the second connecting column limits the thermocouple in the horizontal direction, which can increase the stability of the connection between the thermocouple and the burner head.

[0010] Exemplarily, the stove base further has an outer ring bottom wall, which is arranged outside the installation bottom wall, and the installation bottom wall is recessed toward the top surface relative to the outer ring bottom wall to form a groove, and the height of the second connecting column is not greater than the depth of the groove. In this way, the second connecting column is hidden in the groove, and when placed on the table, it is prevented that the second connecting column protrudes outside the installation bottom wall, causing the stove head to be placed unstable.

[0011] According to another aspect of the utility model, a burner is provided, comprising a thermocouple and the burner head as described above, wherein the thermocouple comprises a first section, a second section and a third section connected in sequence, wherein the diameter of the first section and the diameter of the third section are both smaller than the diameter of the second section, the diameter of the first section, the diameter of the second section and the diameter of the third section are all smaller than the diameter of the first hole, the diameter of the second section is larger than the diameter of the second hole, and the diameter of the third section is not larger than the diameter of the second hole. The burner provided by the utility model, since it comprises the burner head as described above, the burner must have the technical effect of the burner head as described above. Furthermore, the first section, the second section and the third section of the thermocouple can all pass through the first hole, and then the third section of the thermocouple passes through the second hole and the second section moves to the second hole, so that the thermocouple is connected to the second hole of the burner seat.

[0012] Exemplarily, the end of the third section away from the second section is connected with a wire, and the diameter of the wire is smaller than the minimum width of the first connecting groove. In this way, the wire provides energy to the thermocouple, and the wire can pass through the first connecting groove to enable the thermocouple to move between the first hole and the second hole.

[0013] Exemplarily, the burner also includes a flame distribution plate, and a first positioning hole, a second positioning hole, and a second connecting groove are provided on the flame distribution plate. The first positioning hole corresponds to the first hole, and the second positioning hole corresponds to the second hole. The first positioning hole and the second positioning hole are connected through the second connecting groove, and the diameter of the first positioning hole is greater than the diameter of the second positioning hole. In this way, the thermocouple passes through the first hole and the first positioning hole in sequence, and after the third section of the thermocouple passes through the second positioning hole and the second hole in sequence, the second section is penetrated at the second positioning hole and the second section is moved above the second hole, so that the thermocouple is connected to the flame distribution plate and the burner, and the second positioning hole can limit the second section in the horizontal direction.

[0014] Exemplarily, the diameter of the first section, the diameter of the second section and the diameter of the third section are all smaller than the diameter of the first positioning hole, and the diameter of the second section is not larger than the diameter of the second positioning hole. In this way, the first section, the second section and the third section of the thermocouple can all pass through the first positioning hole, and then the third section of the thermocouple passes through the second positioning hole and the second section is inserted into the second positioning hole, so that the thermocouple is connected to the flame distribution plate and the burner, and the second positioning hole can limit the second section in the horizontal direction.

[0015] For example, the second connecting groove has a second width in the first direction, the second width is smaller than the diameter of the second positioning hole, and the first direction is perpendicular to the line connecting the center of the first positioning hole and the center of the second positioning hole. In this way, the thermocouple can be confined in the second positioning hole, so that the thermocouple cannot move outside the second positioning hole through the second connecting groove.

[0016] Exemplarily, the burner further comprises a liquid collecting tray arranged above the fire distribution tray, the liquid collecting tray is provided with a through hole, and the first section is penetrated through the through hole. In this way, the thermocouple can pass through the liquid collecting tray, and the liquid collecting tray can limit the first section in the horizontal direction.

[0017] Exemplarily, the burner also includes a fire cover seat arranged above the fire distribution plate, and the projection of the fire cover seat on the fire distribution plate covers the thermocouple. The thermocouple is hidden under the fire cover seat, and the fire cover seat can protect the thermocouple and prevent the thermocouple from being damaged by bumps.

[0018] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

[0032] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0033] According to one aspect of the present invention, a burner head is provided, and the burner head can be applied to a burner. Therefore, according to another aspect of the present invention, a burner is provided.

[0034] The furnace head will first be described in detail below in conjunction with the accompanying drawings.

[0035] Combined with reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Fig. 9 The furnace head 10 includes a furnace base 100 having a mounting bottom wall 110, and a thermocouple penetration hole 111 is penetrated through the mounting bottom wall 110. The thermocouple penetration hole 111 includes a first hole 1111, a second hole 1112 and a first connecting groove 1113. The first hole 1111 is connected to the second hole 1112 through the first connecting groove 1113, and the diameter of the first hole 1111 is greater than the diameter of the second hole 1112.

[0036] The burner head 10 provided by the utility model has a thermocouple insertion hole 111 passing through the installation bottom wall 110, and the thermocouple insertion hole 111 includes a first hole 1111, a second hole 1112 and a first connecting groove 1113. When applied to the burner 1, the thermocouple 20 can first pass through the first hole 1111 from bottom to top and then move to the second hole 1112, so that the thermocouple 20 is connected to the installation bottom wall 110 without the need for fasteners. On the one hand, the cost of fasteners can be reduced. On the other hand, there is no need to spend time connecting fasteners, thereby improving production efficiency and avoiding the problem of injuries to the hands of cleaning personnel due to exposed fasteners.

[0037] In one embodiment of the present invention, the first hole 1111 and the second hole 1112 are two intersecting circles, and the first connecting groove 1113 is located at the position of the common chord of the first hole 1111 and the second hole 1112 .

[0038] See also Figure 1 and Fig. 9 The first connecting groove 1113 is in the first direction (such as Figure 1The thermocouple 20 has a first width in the X direction (in the middle X direction), the first width is smaller than the diameter of the second hole 1112, and the first direction is perpendicular to the line connecting the center of the first hole 1111 and the center of the second hole 1112. When applied to the burner 1, the thermocouple 20 can be restricted in the second hole 1112, so that the thermocouple 20 cannot move to the outside of the second hole 1112 through the first connecting groove 1113.

[0039] Combined with reference Figure 2 , Figure 4 and Fig. 9 The installation bottom wall 110 has a bottom surface 112 and a top surface 113 which are arranged opposite to each other, and the top surface 113 is provided with a first connecting column 1131 extending from the periphery of the second hole 1112 in a direction away from the bottom surface 112. When applied to the burner 1, the thermocouple 20 contacts the first connecting column 1131 when passing through the second hole 1112, and the contact area between the thermocouple 20 and the installation bottom wall 110 is increased, and the first connecting column 1131 limits the thermocouple 20 in the horizontal direction, which can increase the stability of the connection between the thermocouple 20 and the burner head 10.

[0040] In one embodiment of the present invention, the diameter of the first connecting column 1131 is connected to the diameter of the second hole 1112 , and the diameter of a portion of the thermocouple 20 is larger than the diameter of the first connecting column 1131 , so that the thermocouple 20 can move to the first connecting column 1131 .

[0041] Combined with reference Figure 1 , Figure 2 and Fig. 9 The installation bottom wall 110 has an inner circle 1101 and an outer circle 1102, and the stove base 100 also has an inner side wall 120 and an outer side wall 130, the inner side wall 120 is connected to the inner circle 1101, and the outer side wall 130 is connected to the outer circle 1102, and the height of the first connecting column 1131 relative to the top surface 113 is not greater than the height of the inner side wall 120 or the outer side wall 130 relative to the top surface 113. When applied to the burner 1, when the burner head 10 needs to be connected to a device such as a fire distribution plate 30, the height of the first connecting column 1131 is not greater than the height of the inner side wall 120 or the outer side wall 130, and when the fire distribution plate 30 is covered on the outer side wall 130 of the burner head 10, the first connecting column 1131 will not affect the connection between the fire distribution plate 30 and the outer side wall 130 of the burner head 10.

[0042] Combined with reference Figure 2 , Figure 5 and Fig. 9The bottom surface 112 is formed with a second connecting column 1121 extending from the periphery of the second hole 1112 in a direction away from the top surface 113. When applied to the burner 1, the thermocouple 20 contacts the second connecting column 1121 when passing through the second hole 1112, and the contact area between the thermocouple 20 and the installation bottom wall 110 is increased. The second connecting column 1121 limits the thermocouple 20 in the horizontal direction, which can increase the stability of the connection between the thermocouple 20 and the burner head 10.

[0043] In one embodiment of the present invention, the diameter of the second connecting column 1121 is connected to the diameter of the second hole 1112, and the part of the thermocouple 20 that can pass through the second hole 1112 can also pass through the second connecting column 1121 smoothly, thereby increasing the contact area between the thermocouple 20 and the installation bottom wall 110.

[0044] Combined with reference Figure 1 , Figure 2 and Figure 4 The stove base 100 also has an outer ring bottom wall 140, which is arranged outside the installation bottom wall 110. The installation bottom wall 110 is recessed toward the top surface 113 relative to the outer ring bottom wall 140 to form a groove 101, and the height of the second connecting column 1121 is not greater than the depth of the groove 101. The second connecting column 1121 is hidden in the groove 101. When placed on a table, the second connecting column 1121 is prevented from protruding outside the installation bottom wall 110, which causes the stove head 10 to be placed unstable.

[0045] According to another aspect of the present invention, a burner 1 is provided. Figure 1 , Figures 4 to 9 , including a thermocouple 20 and the burner head 10 as described above, the thermocouple 20 includes a first section 210, a second section 220 and a third section 230 connected in sequence, the diameter of the first section 210 and the diameter of the third section 230 are both smaller than the diameter of the second section 220, the diameter of the first section 210, the diameter of the second section 220 and the diameter of the third section 230 are all smaller than the diameter of the first hole 1111, the diameter of the second section 220 is larger than the diameter of the second hole 1112, and the diameter of the third section 230 is not larger than the diameter of the second hole 1112. The burner 1 provided by the utility model, because it includes the burner head 10 as described above, the burner 1 must have the technical effect of the burner head 10 as described above. Furthermore, the first section 210 , the second section 220 and the third section 230 of the thermocouple 20 can all pass through the first hole 1111 , and then the third section 230 of the thermocouple 20 passes through the second hole 1112 and then the second section 220 moves to the second hole 1112 , so that the thermocouple 20 is connected to the second hole 1112 of the furnace seat 100 .

[0046] When the thermocouple 20 is connected to the mounting bottom wall 110, the thermocouple 20 passes through the first hole 1111 from bottom to top. Generally, a wire is connected to the lower part of the third section 230, and part of the wire is located in the first hole 1111 at this time. The wire passes through the first connecting groove 1113 from the first hole 1111 and enters the second hole 1112. The thermocouple 20 is moved downward and passed through the second hole 1112. The diameter of the second section 220 on the thermocouple 20 is larger than the diameter of the second hole 1112, so that the second section 220 is moved to the second hole 1112 and positioned at the second hole 1112. The second hole 1112 limits the second section 220 in the vertical direction, so that the thermocouple 20 cannot continue to move downward. Because one end of the wire is connected to the third section 230 and the other end of the wire is connected to a terminal, usually, the size of the terminal is larger than the diameter of the second section 220 and the terminal cannot pass through the second hole 1112. Therefore, when the thermocouple 20 is connected to the installation bottom wall 110, the thermocouple 20 can only be installed from bottom to top.

[0047] In one embodiment of the utility model, the diameter of the second hole 1112 is slightly larger than the diameter of the third section 230, and the diameter of the third section 230 matches the diameter of the second hole 1112, so that the third section 230 can be inserted into the second hole 1112 and the outer surface of the third section 230 can contact the second hole 1112, so that the second hole 1112 can limit the third section 230 in the horizontal direction, and the thermocouple 20 and the furnace head 10 can be stably connected.

[0048] In one embodiment of the present invention, a wire (not shown) is connected to the end of the third section 230 away from the second section 220, and the diameter of the wire is smaller than the minimum width of the first connecting groove 1113. The wire provides energy to the thermocouple 20, and the wire can pass through the first connecting groove 1113 to enable the thermocouple 20 to move between the first hole 1111 and the second hole 1112.

[0049] Combined with reference Figure 1 , Figure 3 , Figure 7 and Fig. 9The burner 1 further comprises a flame distribution plate 30, on which a first positioning hole 310, a second positioning hole 320 and a second connecting groove 330 are provided. The first positioning hole 310 corresponds to the first hole 1111, and the second positioning hole 320 corresponds to the second hole 1112. The first positioning hole 310 and the second positioning hole 320 are connected through the second connecting groove 330, and the diameter of the first positioning hole 310 is greater than the diameter of the second positioning hole 320. The thermocouple 20 passes through the first hole 1111 and the first positioning hole 310 in sequence, and after the third section 230 of the thermocouple 20 passes through the second positioning hole 320 and the second hole 1112 in sequence, the second section 220 is arranged at the second positioning hole 320 and the second section 220 moves to the top of the second hole 1112, so that the thermocouple 20 is connected to the flame distribution plate 30 and the burner head 10, and the second positioning hole 320 can limit the second section 220 in the horizontal direction.

[0050] In one embodiment of the present invention, the diameter of the wire is smaller than the minimum width of the second connecting groove 330. The wire provides energy to the thermocouple 20, and the wire can pass through the second connecting groove 330 to enable the thermocouple 20 to move between the first positioning hole 310 and the second positioning hole 320.

[0051] Combined with reference Figure 1 , Figure 3 and Figure 7 , the diameters of the first section 210, the second section 220 and the third section 230 are all smaller than the diameter of the first positioning hole 310, and the diameter of the second section 220 is not larger than the diameter of the second positioning hole 320. The first section 210, the second section 220 and the third section 230 of the thermocouple 20 can all pass through the first positioning hole 310, and then the third section 230 of the thermocouple 20 passes through the second positioning hole 320 and the second section 220 is arranged at the second positioning hole 320, so that the thermocouple 20 is connected to the flame distribution plate 30 and the burner 10, and the second positioning hole 320 can limit the second section 220 in the horizontal direction.

[0052] In one embodiment of the utility model, the fire dividing tray 30 and the burner head 10 can be fastened and connected by fasteners before leaving the factory. During transportation, the fasteners, the fire dividing tray 30 and the burner head 10 can be transported synchronously, reducing the possibility of parts loss, and can reduce on-site operation steps during installation, saving on-site installation time. Therefore, during on-site installation, the thermocouple 20 is directly installed on the connection structure between the flame divider 30 and the burner head 10, and the diameter of the first positioning hole 310 can be the same as the diameter of the first hole 1111, so that the first section 210, the second section 220 and the third section 230 of the thermocouple 20 can all pass through the first positioning hole 310, and the diameter of the second positioning hole 320 matches the diameter of the second section 220, and the diameter of the second positioning hole 320 is slightly larger than the diameter of the second section 220, so that the second section 220 can be inserted into the second positioning hole 320 and the outer surface of the second section 220 can contact the second positioning hole 320, so that the second positioning hole 320 can limit the second section 220 in the horizontal direction, and the thermocouple 20 and the flame divider 30 can be stably connected.

[0053] Combined with reference Figure 3 and Figure 4 The second connecting groove 330 has a second width in the first direction, the second width is smaller than the diameter of the second positioning hole 320, and the first direction is perpendicular to the line connecting the center of the first positioning hole 310 and the center of the second positioning hole 320. The thermocouple 20 can be confined in the second positioning hole 320, so that the thermocouple 20 cannot move to the outside of the second positioning hole 320 through the second connecting groove 330.

[0054] In one embodiment of the present invention, the diameter of the wire is smaller than the second width of the first connecting groove 1113. The wire provides energy to the thermocouple 20, and the wire can pass through the second connecting groove 330 to enable the thermocouple 20 to move between the first positioning hole 310 and the second positioning hole 320.

[0055] Combined with reference Figures 6 to 9 The burner 1 further comprises a liquid collecting tray 40 disposed above the fire distribution tray 30, the liquid collecting tray 40 is provided with a through hole 410, and the first section 210 is passed through the through hole 410. The thermocouple 20 can pass through the liquid collecting tray 40, and the liquid collecting tray 40 can limit the first section 210 in the horizontal direction.

[0056] Combined with reference Figure 3 and Figure 7 The diameter of the through hole 410 is smaller than the diameter of the second section 220 , and the collecting tray 40 presses the second section 220 into the second positioning hole 320 . The collecting tray 40 limits the thermocouple 20 in the vertical direction so that the thermocouple 20 cannot move upward.

[0057] Combined with reference Figure 8 and Fig. 9The burner 1 further comprises a fire cover seat 50 disposed above the fire distribution plate 30, and the projection of the fire cover seat 50 onto the fire distribution plate 30 covers the thermocouple 20. The first section 210 of the thermocouple 20 is hidden under the fire cover seat 50, and the fire cover seat 50 can protect the thermocouple 20 and prevent the thermocouple 20 from being damaged by bumps.

[0058] In one embodiment of the present utility model, Figure 8 and Fig. 9 An inner ring fire cover 60 and an outer ring fire cover 70 are installed on the fire cover seat 50. Fire holes are provided on the outer walls of the inner ring fire cover 60 and the outer ring fire cover 70.
