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] A burner is a device that mixes gas and air in a certain way before burning. A burner usually has a burner head, which mostly includes a burner head seat, a flame distribution plate, a liquid collecting plate, and a fire cover seat. The burner head seat, the flame distribution plate, and the liquid collecting plate are connected to each other with fasteners such as screws. The fasteners often protrude from the outside of the burner head seat and the liquid collecting plate, so that the screw heads and nuts are exposed on the bottom wall of the burner head seat and the surface of the liquid collecting plate, which can easily cause damage to the hands of the cleaning staff during cleaning. Although some burners cover the screw heads and nuts protruding from the surface of the liquid collecting plate by increasing the area of ​​the fire cover seat, this will increase the production cost of the fire cover seat. 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 burner head includes a burner head seat, which has a bottom wall, an outer wall and an inner wall. The outer wall, the bottom wall and the inner wall enclose an air dividing cavity. The outer wall has an inner side surface facing the inner wall. A mounting portion protrudes from the inner side surface toward the inner wall. A fastener connecting hole is provided on the mounting portion. The center line of the fastener connecting hole is perpendicular to the bottom wall.

[0005] The burner head provided by the utility model has a mounting portion protruding toward the inner wall on the inner side surface of the outer wall, and the mounting portion is provided with a fastener connecting hole perpendicular to the bottom wall. When applied to the burner, the fastener can be connected to the fastener connecting hole to fix the burner head and the fire distribution plate, and the fastener can be prevented from being exposed to the outer wall without increasing the manufacturing cost of the fire cover seat, thereby avoiding the problem of injury to the hands of cleaning personnel due to the exposed fastener.

[0006] Exemplarily, there are at least two mounting portions, which are spaced apart along the circumference of the outer side wall. In this way, when applied to a burner, the firmness of the connection between the fire distribution plate and the burner head can be increased.

[0007] Exemplarily, the mounting portion has an outer side facing the inner side wall, and the outer side is in an arc shape. In this way, the surface of the outer side of the mounting portion can form a turbulent flow for the gas entering the gas separation cavity, increase the residence time of the gas at the outer side, and then increase the residence time of the gas in the gas separation cavity, so that the gas and air are mixed more evenly in the gas separation cavity.

[0008] Exemplarily, the arc radius of the outer side is 4 mm to 6 mm, for example, 4 mm, 5 mm or 6 mm, etc., so that the fastener connection hole can accommodate fasteners with a nominal diameter of 4 mm, 5 mm or 6 mm, and at the same time, the arc-shaped outer side forms a disturbed airflow on the surface of the outer side of the mounting portion.

[0009] Exemplarily, the depth of the fastener connection hole is 15 mm to 20 mm. For example, 15 mm, 18 mm or 20 mm, etc. In this way, the depth of the fastener connection hole is greater than the thickness of the bottom wall or the outer wall, and the contact area between the fastener and the fastener connection hole is increased. When applied to the burner, the stability of the connection between the flame distribution plate and the burner head can be increased.

[0010] For example, an ejector tube connecting the outside and the gas separation cavity is provided on the bottom wall, the ejector tube has an air bleed outlet, the mounting portion has a bottom end, and the air bleed outlet is not higher than the bottom end. In this way, since the gas flows from the air bleed outlet toward the gas separation cavity, the air bleed outlet is not higher than the bottom end of the mounting portion, and the gas flowing out of the air bleed outlet will not be blocked by the mounting portion and change the diffusion direction, and can be smoothly diffused into the gas separation cavity, so that the gas in the gas separation cavity is uniform.

[0011] According to another aspect of the utility model, a burner is provided, comprising a flame distribution plate and the burner head as described above, wherein the flame distribution plate is provided with a mounting hole corresponding to the fastener connection hole, the mounting hole is penetrated by a first fastener, and the first fastener is connected to the fastener connection hole. The burner provided by the utility model, because it comprises the burner head as described above, must have the technical effect of the burner head as described above. Furthermore, the first fastener fastens the flame distribution plate and the burner head.

[0012] Exemplarily, the fire distribution plate has a first surface and a second surface, the first surface and the second surface are arranged opposite to each other, the first surface faces the air distribution cavity, the second surface is away from the air distribution cavity, and the mounting hole runs through the first surface to the second surface. In this way, the first fastener passes through the fire distribution plate and is connected to the burner seat.

[0013] For example, a positioning post is provided on the first surface, and a positioning hole is provided on the positioning post, and the positioning hole extends from the surface of the positioning post away from the first surface toward the first surface. In this way, when a fastener connecting other structures is inserted into the positioning hole, the purpose of hiding the fastener can be achieved.

[0014] For example, a through hole corresponding to the positioning hole is provided on the bottom wall, and the second fastener passes through the through hole and is connected to the positioning hole. In this way, the second fastener can also realize the fastening connection between the fire distribution plate and the burner head, thereby realizing the double fastening connection between the fire distribution plate and the burner head, improving the connection stability between the fire distribution plate and the burner head, and reducing the possibility of gas leakage.

[0015] Exemplarily, the surface of the positioning column away from the first surface abuts against the bottom wall. In this way, not only can the fire distribution plate be supported on the burner, but also the purpose of completely hiding the second fastener can be achieved.

[0016] Exemplarily, the burner further comprises a liquid collecting tray, the liquid collecting tray is provided with a docking hole, and the first fastener passes through the docking hole and the mounting hole in sequence and is connected to the fastener connecting hole. In this way, the first fastener can fix the liquid collecting tray, the fire distribution tray and the burner head together.

[0017] Exemplarily, the burner further comprises a fire cover seat disposed above the fire distribution plate, and the projection of the fire cover seat onto the fire distribution plate covers the mounting hole. In this way, the first fastener and the second fastener are both hidden under the fire cover seat, avoiding the problem of the first fastener and the second fastener being exposed and causing harm to the hands of cleaning personnel.

[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.

In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0034] 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.

[0035] The furnace head will first be described in detail below in conjunction with the accompanying drawings.

[0036] Combined with reference Figures 1 to 4The burner head 100 includes a burner head seat 110, which has a bottom wall 111, an outer wall 112 and an inner wall 113. The outer wall 112, the bottom wall 111 and the inner wall 113 enclose an air dividing cavity 1101. The outer wall 112 has an inner side surface 1121 facing the inner side wall 113. The inner side surface 1121 has a mounting portion 114 protruding toward the inner side wall 113, wherein the mounting portion 114 and the bottom wall 111 may be abutted against each other, and a gap may be left between the mounting portion 114 and the bottom wall 111. A fastener connecting hole 1141 is provided on the mounting portion 114, and the center line of the fastener connecting hole 1141 is perpendicular to the bottom wall 111.

[0037] The burner head 100 provided by the utility model has a mounting portion 114 protruding toward the inner wall 113 on the inner side surface 1121 of the outer wall 112, and a fastener connecting hole 1141 perpendicular to the bottom wall 111 is provided on the mounting portion 114. When applied to the burner, the fastener can be connected to the fastener connecting hole 1141 to fix the burner head 100 and the fire distribution plate 200. The fastener can be prevented from being exposed to the outer wall 112 without increasing the manufacturing cost of the fire cover seat, thereby avoiding the problem of injury to the hands of cleaning staff caused by the exposed fastener.

[0038] Combined with reference Figure 1 , Figure 2 and Figure 4 There are at least two mounting portions 114, and the two mounting portions 114 are spaced apart along the circumference of the outer side wall 112. When applied to a burner, the firmness of the connection between the fire distribution plate 200 and the burner head 100 can be increased.

[0039] In one embodiment of the present invention, there are four mounting portions 114, and the four mounting portions 114 are evenly spaced in the circumferential direction, such as Figure 2 As shown, every two adjacent mounting portions 114 are spaced 90 degrees apart from each other, and the gas passes through the mounting portions 114 and collides with the mounting portions 114 to produce a velocity change, and the spaced mounting portions 114 are symmetrically arranged, so that the difference in the flow velocity change of the gas at various locations in the gas dividing cavity 1101 is minimized, so that the gas can be evenly distributed in the gas dividing cavity 1101. The fastener connection holes 1141 are evenly distributed around the inner side surface 1121, and the fasteners are subjected to balanced force during connection, thereby increasing the stability of the installation.

[0040] Combined with reference Figure 1 and Figure 2 The mounting portion 114 has an outer side edge 1142 facing the inner side wall 113, and the outer side edge 1142 is in an arc shape. The surface of the outer side edge 1142 of the mounting portion 114 can form a turbulent flow for the gas entering the gas dividing cavity 1101, thereby increasing the residence time of the gas at the outer side edge 1142, thereby increasing the residence time of the gas in the gas dividing cavity 1101, and making the gas and air mixed more evenly in the gas dividing cavity 1101.

[0041] See also Figure 2 and Figure 4 In one embodiment of the present invention, the central angle of the arc-shaped outer side 1142 is greater than 180 degrees, so that when the diameter of the mounting portion 114 is small, the fastener connecting hole 1141 on the mounting portion 114 can be large enough to accommodate the fastener.
