Description

Technical Field

[0001] This utility model relates to a component of a household gas stove, and more particularly to a nozzle seat for a household gas stove. Background Technology

[0002] As users' demands for the quality of household gas stoves continue to increase, top-air-intake stoves can reduce the occurrence of glass panel breakage, and their market share is constantly increasing. Top-air-intake stoves mostly adopt a structure with a nozzle seat. However, the primary and secondary air required by the burner of the nozzle seat structure enters from the panel, which has the disadvantage of limiting the heat load of the stove. Summary of the Invention

[0003] The purpose of this invention is to provide a nozzle holder with an ejector tube that has a reasonable structure, simple process, economical material usage, high combustion heat load and high thermal efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution. A nozzle holder with an ejector tube includes a base frame. Water tray mounting feet are provided at both the left and right ends of the base frame. A high-fire nozzle mounting block is provided on the upper part of the water tray mounting feet. The high-fire nozzle mounting block has a high-fire nozzle mounting hole and a burner positioning surface. A water tray mounting hole is provided on the outer side of the water tray mounting feet. A high-fire air inlet pipe and a low-fire ejector tube are respectively connected in the middle of the base frame. The high-fire air inlet pipe is connected to two high-fire nozzles installed in the high-fire nozzle mounting holes via left and right branch pipes. The low-fire ejector tube is arranged in a V-shape with the high-fire air inlet pipe. One end of the low-fire ejector tube is connected to a low-fire air outlet pipe located in the middle of the base frame, and the other end is connected to a rectangular air inlet box located on the outer side. A low-fire nozzle mounting nut is provided on the outer side of the rectangular air inlet box, and the low-fire nozzle is installed in the low-fire nozzle mounting nut.

[0005] The nozzle holder with ejector tube has a symmetrically arranged bidirectional arrow-shaped structure, and the holder is in the form of a triangular support.

[0006] The nozzle seat with ejector tube has a thread on the outer ring of the small flame outlet of the small flame outlet pipe, which is locked with a nut to fix the water tray.

[0007] This utility model has the following beneficial effects due to the adoption of the above-mentioned technical solutions: (i) It is due to the innovative design of the small flame ejector tube and the nozzle seat combined into a structure, so that the nozzle seat has the ejector function; (ii) It is due to the innovative design of the outer square air inlet, so that the small flame air can be introduced from the outside, increasing the primary air introduction and improving the heat load and thermal efficiency of the burner; (iii) It is due to the innovative design of the burner positioning surface at the bottom of the large flame mounting hole, so that the burner can be positioned on this surface, making the burner installation accurate and convenient; (iv) It is due to the innovative design of the outer ring thread of the small flame air outlet, so that the center of the water pan fits tightly with the nozzle seat, while eliminating the need for screw locking process, reducing material usage and saving costs.

[0011] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0012] like Figure 1 , Figure 2 and Figure 3 As shown, the nozzle holder with ejector tube includes a base frame 1. Water tray mounting feet 2 are provided at both ends of the base frame 1. A high-fire nozzle mounting block 3 is provided on the upper part of the water tray mounting feet 2. A high-fire nozzle mounting hole 4 and a burner positioning surface 5 are provided on the high-fire nozzle mounting block 3. A water tray mounting hole 6 is provided on the outer side of the water tray mounting feet 2. A high-fire air inlet pipe 7 and a low-fire ejector tube 8 are connected to the middle part of the base frame 1. The high-fire air inlet pipe 7 is connected to two high-fire nozzles 10 installed in the high-fire nozzle mounting holes 4 via left and right branch pipes 9. The low-fire ejector tube 8... The small flame injector tube 8 is arranged in a V-shape with the main flame air intake pipe 7. One end of the small flame injector tube 8 is connected to the small flame air outlet pipe 11 located in the middle of the base frame 1, and the other end is connected to the rectangular air intake box 12 located on the outside. A small flame nozzle mounting nut 13 is provided on the outside of the rectangular air intake box 12. The small flame nozzle 14 is installed in the small flame nozzle mounting nut 13. A thread 15 is provided on the outer ring of the small flame air outlet 17 of the small flame air outlet pipe 11, which is locked with the nut 16 to fix the water tray. The base frame 1 is a symmetrically arranged bidirectional arrow-shaped structure and is in the form of a triangular support.
