Description

Technical Field

[0001] The utility model relates to the field of stoves, in particular to a stove. Background Art

[0002] At present, the plug-in valve burner is widely used by manufacturers on gas cookers due to its low cost and easy installation. Generally, the nozzle is set on the plug-in valve, and the plug-in valve is connected by plugging the nozzle into the central mounting hole of the ejector to complete the assembly. However, in order to facilitate installation and take into account the manufacturing tolerance of the parts, the central mounting hole of the ejector and the nozzle are gap-assembled, and the single-side gap of the circular hole can reach 1mm. This can easily cause the central axis of the nozzle and the ejector to deviate, thereby weakening the one-time ejection capacity, resulting in excessive smoke and low combustion efficiency. If the assembly gap is reduced by reducing the diameter of the central mounting hole, an interference fit may be formed between some nozzles and the ejector due to the existence of manufacturing tolerances. Since the material of the nozzle is relatively hard, the assembly of the nozzle and the ejector is extremely difficult in the case of interference fit, or even impossible to assemble, which greatly reduces the assembly efficiency of the assembly line. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a stove in order to overcome the defect in the prior art that the central axis of the nozzle and the ejector is easily deflected.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A stove, comprising a burner, a panel and a bottom box, wherein the valve tube assembly and an ejector of the burner are both arranged on the bottom box, and the stove also comprises a bracket, wherein the bracket is provided with a first mounting groove and a second mounting groove which penetrate the bracket along the axial direction of the ejector, and the first mounting groove is coaxially arranged with the second mounting groove; the ejector is embedded in the first mounting groove, and the ejector is coaxially arranged with the first mounting groove, the valve tube assembly is embedded in the second mounting groove, and the valve tube assembly is coaxially arranged with the second mounting groove; and the lower surface of the panel is used to limit the freedom of movement of the bracket in the vertical upward direction.

[0006] A bracket is arranged in the cooker, and the first mounting groove and the second mounting groove on the bracket are coaxially arranged, the first mounting groove and the second mounting groove of the bracket are respectively embedded with the ejector and the valve tube assembly, and the first mounting groove is coaxially assembled with the ejector, and the second mounting groove is coaxially assembled with the valve tube assembly. Since the lower surface of the panel can limit the freedom of movement of the bracket in the vertical upward direction, the bracket can remain stable and will not flip over. Under the fixing and limiting action of the bracket, the ejector and the valve tube assembly are ensured to be coaxial. Since the valve tube assembly and the nozzle are coaxially assembled through a threaded structure, the nozzle and the ejector are ensured to be coaxial, thereby avoiding deviation of the central axes of the nozzle and the ejector.

[0007] Preferably, the bracket includes a heat insulating portion, the heat insulating portion is arranged on a side of the bracket close to the ejector, and the heat insulating portion abuts against a lower surface of the panel.

[0008] By providing a heat insulating portion, the heat insulating portion abuts against the lower surface of the panel, which can not only prevent the bracket from flipping over by abutting against the panel, but also play a heat insulating role to prevent the temperature of the valve pipe assembly from rising too much.

[0009] Preferably, the second mounting groove has a double-layer structure, and the double-layer structure is arranged at intervals along the axial direction of the ejector.

[0010] By configuring the second mounting groove to have a double-layer structure, the valve tube assembly has a double-layer limit, so that the bracket has a better fixing effect on the valve tube assembly and the overall structure is more reliable.

[0011] Preferably, a single-sided assembly gap between the first mounting groove and the ejector is less than 0.3 mm.

[0012] By setting the single-sided assembly clearance between the first mounting groove and the ejector to be less than or equal to 0.3 mm, the coaxiality between the first mounting groove and the ejector is ensured to be within an acceptable range.

[0013] Preferably, a single-side assembly clearance between the second mounting groove and the valve tube assembly is less than 0.3 mm.

[0014] By setting the single-sided assembly clearance between the second mounting groove and the valve tube assembly to be less than or equal to 0.3 mm, the coaxiality between the first mounting groove and the ejector is ensured to be within an acceptable range.

[0015] Preferably, the valve tube assembly has a mounting section, and the mounting section is embedded in the second mounting groove.

[0016] By setting the connection position between the second installation groove and the valve pipe assembly as the installation section of the valve pipe assembly,

[0017] Preferably, along the axial direction of the ejector, the length of the second mounting groove is smaller than the length of the mounting section.

[0018] By setting the length of the second mounting groove to be smaller than the length of the mounting section, it is prevented that the second mounting groove is separated from the mounting section, which would cause the second mounting groove and the valve pipe assembly to be unreliably fixed.

[0019] Preferably, the stove further includes a bottom box, and the bracket further includes a supporting portion, and a side of the supporting portion close to the bottom box abuts against the bottom box.

[0020] By arranging the support portion of the bracket to abut against the bottom box, the bracket is further prevented from turning over.

[0021] Preferably, the bracket also includes a connecting plane and a first connecting portion, the first mounting groove is arranged on the first connecting portion, the connecting plane is connected to the first connecting portion and the supporting portion, and the inner wall of the connecting plane close to the burner side of the stove abuts against the outer wall of the ejector.

[0022] By bringing the inner wall of the connecting plane close to the burner head of the stove into contact with the outer wall of the ejector, the connecting plane also has a limiting effect on the ejector, so that the bracket has a better fixing effect on the ejector.

[0023] Preferably, the first connecting portion, the supporting portion and the connecting plane are integrally formed.

[0024] The positive progressive effect of the present utility model is that a bracket is arranged in the cooker, and the first mounting groove and the second mounting groove on the bracket are coaxially arranged, the first mounting groove and the second mounting groove of the bracket are respectively embedded with the ejector and the valve tube assembly, and the first mounting groove is coaxially assembled with the ejector, and the second mounting groove is coaxially assembled with the valve tube assembly. Since the lower surface of the panel can limit the freedom of movement of the bracket in the vertical upward direction, the bracket can remain stable and will not flip over. Under the fixing and limiting action of the bracket, the ejector and the valve tube assembly are ensured to be coaxial. Since the valve tube assembly and the nozzle are coaxially assembled through a threaded structure, the nozzle and the ejector are ensured to be coaxial, thereby avoiding deviation of the central axis of the nozzle and the ejector.

[0050] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0051] like Figure 1-Figure 6As shown, the present embodiment provides a cooker 1, which includes a burner 100, a panel 200 and a bottom box 300, wherein the valve tube assembly 110 and the ejector 120 of the burner 100 are both arranged on the bottom box 300, and the cooker 1 also includes a bracket 400, on which a first mounting groove 411 and a second mounting groove 421 are arranged that penetrate the wall thickness of the bracket 400 along the axial direction of the ejector 120, the first mounting groove 411 and the second mounting groove 421 are coaxially arranged, the ejector 120 is embedded in the first mounting groove 411, and the ejector 120 is coaxially arranged with the first mounting groove 411, the valve tube assembly 110 is embedded in the second mounting groove 421, and the valve tube assembly 110 is coaxially arranged with the second mounting groove 421, and the lower surface of the panel 200 is used to limit the freedom of movement of the bracket 400 in the vertical upward direction.

[0052] By arranging the bracket 400 in the cooker 1, and the first mounting groove 411 and the second mounting groove 421 on the bracket 400 are coaxially arranged, the first mounting groove 411 and the second mounting groove 421 of the bracket 400 are respectively embedded with the ejector 120 and the valve tube assembly 110, and the first mounting groove 411 is coaxially assembled with the ejector 120, and the second mounting groove 421 is coaxially assembled with the valve tube assembly 110. Since the lower surface of the panel 200 can limit the freedom of movement of the bracket 400 in the vertical upward direction, the bracket 400 can remain stable and will not flip over. Under the fixing and limiting action of the bracket 400, the ejector 120 and the valve tube assembly 110 are ensured to be coaxial. Since the valve tube assembly 110 and the nozzle 113 are coaxially assembled through the threaded structure, the nozzle 113 and the ejector 120 are ensured to be coaxial, thereby avoiding the deviation of the central axis of the nozzle 113 and the ejector 120.

[0053] Specifically, if Figure 1 and Figure 2 As shown, in this embodiment, two burners are arranged on the cooker 1, and each burner is correspondingly provided with two ejectors 120, and each burner is correspondingly provided with a bracket 400, so each bracket 400 is respectively provided with two first mounting grooves 411 arranged in parallel corresponding to the two ejectors 120, and the two ejectors 120 are respectively embedded in the two first mounting grooves 411, and the valve pipe assembly 110 includes a valve body 112 and a valve stem 111, and each valve stem 111 is connected to a nozzle 113. Like the ejector 120, each valve pipe assembly 110 also has two valve stems 111, and correspondingly thereto there are also two second mounting grooves 421, and the two valve stems 111 are respectively embedded in the two second mounting grooves 421.

[0054] Among them, the valve tube assembly 110 and the ejector 120 mentioned in this embodiment are coaxial, specifically referring to that each valve stem 111 of the valve tube assembly 110 is coaxial with the corresponding ejector 120, and the valve tube assembly 110 is coaxial with the second mounting groove 421, specifically referring to that each valve stem 111 is coaxial with the second mounting groove 421 in which it is embedded. For ease of installation, the cross-sections of the first mounting groove 411 and the second mounting groove 421 are both semicircular, and the center of the cross-section of the first mounting groove 411 and the center of the cross-section of the second mounting groove 421 coincide with the axis of the ejector 120, wherein the opening of the first mounting groove 411 faces downward, and the opening of the second mounting groove 421 faces upward. During installation, the burner head is first fixed on the base box 300, and the ejector 120 is also fixed accordingly. Then, the bracket 400 is installed, and the ejector 120 is embedded in the first mounting groove 411. Then, the valve tube assembly 110 is installed, and the valve stem 111 of the valve tube assembly 110 is embedded in the second mounting groove 421. Finally, the panel 200 is installed.

[0055] In this embodiment, if Figure 3 and Figure 4 As shown, the bracket 400 includes a heat insulating portion 440, which is arranged on a side of the bracket 400 close to the ejector 120. The heat insulating portion 440 abuts against the lower surface of the panel 200, thereby limiting the freedom of vertical upward movement of the bracket 400. At the same time, since the heat insulating portion 440 abuts against the lower surface of the panel 200, the heat insulating portion 440 separates the burner head and the valve tube assembly 110 of the stove 1, which can block the heat radiation from the burner head, greatly reduce the temperature rise of the valve tube assembly 110, and avoid excessive temperature rise of the valve body 112 in the valve tube assembly 110.

[0056] Of course, in other embodiments, the heat insulating portion 440 may not abut against the lower surface of the panel 200, but there is a gap of 3 mm between the heat insulating portion 440 and the lower surface of the panel 200, so that the panel 200 can limit the freedom of the bracket 400 to move vertically upward, and the panel 200 will not interfere with the bracket 400, thereby reducing the difficulty of assembling the cooker 1. Of course, under the premise that the bracket 400 and the panel 200 do not interfere with each other, the gap between the heat insulating portion 440 and the panel 200 is as small as possible.

[0057] In this embodiment, if Figure 5As shown, the bracket 400 includes a connecting plane 430, a first connecting portion 410 and a second connecting portion 420, the first mounting groove 411 is arranged on the first connecting portion 410, the second mounting groove 421 is arranged on the second connecting portion 420, the connecting plane 430 connects the first connecting portion 410 and the second connecting portion 420, wherein, on the side of the connecting plane 430 close to the burner head, the inner wall of the connecting plane 430 abuts against the outer wall of the ejector 120, that is, the connecting plane 430 has a hollow structure inside on the side close to the burner head, and this hollow structure While being able to accommodate the ejector 120, the inner wall of the connecting plane 430 abuts against the outer wall of the ejector 120, and the height of the connecting plane 430 is slightly higher than the height of the axis of the ejector 120. The first installation groove 411 is smaller than the horizontal projection area of ​​the ejector 120 surrounded by it. Since the ejector 120 is installed first, and then the bracket 400 is placed from top to bottom and installed on the stove 1, the outer wall of the ejector 120 can provide upward support for the bracket 400, making the installation of the bracket 400 more secure. Figure 6 As shown, the height of the position where the connecting plane 430 is located is slightly higher than the height of the position where the axis of the ejector 120 is located, and there is a distance H between the height where the axis of the ejector 120 is located and the height where the connecting plane 430 is located, where H>0. By abutting the inner wall of the connecting plane 430 on the side close to the burner head of the stove 1 with the outer wall of the ejector 120, the first mounting groove 411 is smaller than the horizontal projection area of ​​the part of the ejector 120 surrounded by it, and the connecting plane 430 has a limiting effect on the ejector 120, and the ejector 120 also has a supporting effect on the connecting plane 430, so that the overall structure is more stable.

[0058] In addition, the second mounting groove 421 has a double-layer structure, and the double-layer structure is spaced apart along the axial direction of the ejector 120. That is to say, the second connecting portion 420 has a double-layer structure, and there is a certain distance between the double-layer structures of the second connecting portion 420, and they are not fitted along the axial direction of the ejector 120. The valve tube assembly 110 is arranged in the second mounting groove 421, so that the bracket 400 has a double-layer limit for the valve tube assembly 110, and this double-layer limit has a certain distance along the axial direction of the ejector 120, and the bracket 400 has a better fixing effect on the valve tube assembly 110.

[0059] In this embodiment, the unilateral assembly clearance between the first mounting groove 411 and the ejector 120 is less than 0.3 mm, and the unilateral assembly clearance between the second mounting groove 421 and the valve tube assembly 110 is less than 0.3 mm. By setting the unilateral assembly clearance between the first mounting groove 411 and the ejector 120 and the unilateral assembly clearance between the second mounting groove 421 and the valve tube assembly 110 to be less than 0.3 mm, it is ensured that the coaxiality between the first mounting groove 411 and the ejector 120 and the coaxiality between the second mounting groove 421 and the valve tube assembly 110 are within an acceptable range. That is to say, in the prior art, it is known through theoretical calculations and experimental data that when the unilateral assembly clearance between the nozzle 113 and the ejector 120 is less than 0.6 mm, the coaxiality between the nozzle 113 and the ejector 120 has met the actual application requirements, the one-time ejection capability of the ejector 120 will not be seriously affected, and the combustion efficiency of the cooker 1 is high. Therefore, the unilateral assembly gap between the first mounting groove 411 and the ejector 120 and the unilateral assembly gap between the second mounting groove 421 and the valve tube assembly 110 are both set to be less than 0.3 mm, so that the bracket 400 can have an error within a certain range, while satisfying the coaxiality between the valve tube assembly 110 and the ejector 120, that is, while satisfying the coaxiality between the nozzle 113 threadedly connected to the valve tube assembly 110 and the ejector 120, the processing difficulty of the bracket 400 is reduced.

[0060] Specifically, if Figure 4 and Figure 5 As shown, the valve tube assembly 110 has a mounting section 1111, the diameter of the mounting section 1111 is larger than the diameter of other positions of the valve stem 111, and the mounting section 1111 is embedded in the second mounting groove 421, wherein the length of the mounting section 1111 is L, and the distance between the two spaced second mounting grooves 421, that is, the length of the second mounting groove 421 along the axial direction of the ejector 120 is W, and the length W of the second mounting groove 421 is smaller than the length L of the mounting section 1111, so as to prevent the second mounting groove 421 from being separated from the mounting section 1111, resulting in the fixation between the second mounting groove 421 and the valve tube assembly 110 being not firm enough.

[0061] Of course, in other embodiments, the length W of the second mounting groove 421 may also be equal to the length L of the mounting section 1111 .

[0062] In this embodiment, the cooker 1 further includes a support portion 450, and a side of the support portion 450 close to the bottom box 300 abuts against the bottom box 300. By providing the support portion 450, the support portion 450 abuts against the bottom box 300, and the bracket 400 is further prevented from turning over.

[0063] In this embodiment, the support portion 450 is connected to the connecting plane 430, and the connecting plane 430 is integrally formed with the first connecting portion 410, the second connecting portion 420, the heat insulating portion 440 and the support portion 450. The overall structural strength of the bracket 400 is higher. Specifically, in this embodiment, the bracket 400 is formed by bending and welding the sheet metal parts. Of course, in other embodiments, the bracket 400 can also be integrally formed by other processing methods in the prior art. Specifically, Figure 5 As shown, in this embodiment, the heat insulating portion 440 and the first connecting portion 410 are the same planar structure, that is, the functions of the heat insulating portion 440 and the first connecting portion 410 are simultaneously realized through a planar structure on the bracket 400.

[0064] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
