Technical Field
[0001] This utility model relates to the field of commercial kitchen equipment technology, specifically to a box structure for a commercial wok stove. Background Technology
[0002] Traditional restaurant gas-fired woks are typically equipped with multiple burners and a water tank, with a constantly running faucet above the tank. During use, chefs stir-fry food using the gas stove; after cooking, they use the water in the tank to wash the cookware. Normally, the faucet is kept running, causing water from the tank to overflow onto the stove surface, forming a thin water layer to cool the surface and improve safety. However, this method has significant drawbacks: ① The flowing water layer is insufficient, resulting in low heat exchange efficiency and poor cooling; ② While deepening the water tank to create a fixed water layer increases the water layer thickness, it also easily leads to the accumulation of grease and residue, making cleaning difficult and posing hygiene risks. Current technology cannot reconcile the conflicting needs of efficient cooling and ease of cleaning.
[0003] Therefore, there is an urgent need for a stove structure that combines efficient cooling with convenient cleaning, ensuring continuous water cooling while enabling rapid removal of stains. Utility Model Content

[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0031] In the embodiments, such as Figure 1-4 The diagram shows the casing structure of a commercial wok stove, including a main body 1 and a rectangular countertop 2 connected to it. The countertop 2 has a pre-drilled heating port 2.2 and a water storage tank groove 2.3 on its surface 2.1. Three sides of the surface 2.1 have upward-protruding, continuous weirs 2.4, with the other side forming a drainage side 2.5. The drainage side 2.5 is equipped with a detachable baffle 3, forming an openable and closable drainage channel. The main body 1 has a sunken drainage trough 1.1 near the drainage side 2.5, with drainage holes 1.2 at the bottom. The three-sided weirs 2.4 and the baffle 3 form a relatively enclosed water area with a certain depth. Combined with the continuous flow of water in the storage tank, this significantly improves heat exchange efficiency, reducing the temperature of the high-temperature zone of the stove by 40-60℃, and also reduces water flow to a certain extent, thus reducing water waste. Meanwhile, the detachable baffle 3 can open the drainage channel at any time to quickly discharge oil residue during the stir-frying and washing of cookware. Together with the sunken drainage groove 1.1, it achieves directional flow through the drainage hole 1.2, avoiding the retention of oil residue on the rectangular countertop, maintaining the flatness and cleanliness of the rectangular countertop 2 in the existing product, and ensuring hygiene and safety.
[0032] In the embodiments, such as Figure 3 , Figure 4 As shown, the countertop 2.1, heating mounting port 2.2, water tank recess 2.3, and cofferdam 2.4 are formed by one-piece sheet metal stamping. The one-piece sheet metal forming of the countertop 2.1, heating mounting port 2.2, water tank recess 2.3, and cofferdam 2.4 eliminates weld seams, reduces dead corners for oil and dirt adhesion, and improves cleanliness.
[0033] In the embodiments, such as Figure 1 , Figure 3As shown, the drain trough 1.1 and the drain side are arranged closer to the operator. This arrangement facilitates the chef's direct placement or removal of the baffle 3 and makes cleaning easier, conforming to ergonomic operating logic.
[0034] In this embodiment, the detachable structure of the baffle 3 can be magnetic adsorption, bolt connection, pin connection, or snap-fit, all of which allow for quick assembly and disassembly. This embodiment uses magnetic adsorption, specifically as follows: Figure 3 , Figure 4 As shown, the lower surface of the tabletop 2.1 is equipped with retaining rings 2.6 at the positions corresponding to both ends of the retaining strip 3. Magnets 4 are inserted into the retaining rings 2.6, and the retaining strip 3 is made of magnetic material. The magnets 4 inside the retaining rings 2.6 and the white cast iron retaining strip 3 form an attractive force, ensuring sufficient stability. In high-temperature environments, the magnetic force of the magnets 4 may gradually decrease; the insert design facilitates replacement and reduces maintenance costs. Furthermore, the magnetic adsorption mechanism also provides a self-positioning function for the retaining strip 3, facilitating operation.
[0035] In this embodiment, the main body 1 and the rectangular countertop 2 are both made of stainless steel, while the baffle 3 is made of white cast iron rectangular tubing. Both the stainless steel body and the white cast iron have good corrosion resistance, making them suitable for use in humid environments. Furthermore, the ferromagnetism of the white cast iron ensures sufficient attraction between the baffle 3 and the magnet 4.
[0036] In the embodiments, such as Figure 1 , Figure 2 As shown, drain hole 1.2 is connected to drain pipe 1.3, and the other end of drain pipe 1.3 extends to the bottom of the stove body 1. Drain pipe 1.3 extends from drain hole 1.2 to the bottom of the cabinet, forming a directional flow guidance system with good flow guidance performance to avoid pipe blockage or backflow.
[0037] In the embodiments, such as Figure 4 As shown, the back of the tabletop 2.1 is provided with a reinforcing rib 2.7. The reinforcing rib 2.7 is a profile made of stainless steel sheet and welded to the diagonal direction of the back of the tabletop 2.1 to improve the load-bearing capacity and deformation resistance of the tabletop 2.1.
[0038] In the embodiments, such as Figure 2 As shown, the bottom of the stove body 1 is equipped with detachable support legs 5, which are connected to the cabinet by bolts or quick-release clips. In this embodiment, the stove body 1 can be placed on a flat workbench with the support legs 5 removed, or placed on the ground with the support legs 5 attached, or placed on a stepped platform with two support legs 5 installed. The detachable support legs 5 give the stove body 1 good adaptability and can meet the needs of different working scenarios.
[0039] In the embodiments, such as Figure 1 , 2As shown, it also includes a back panel 6, which is installed on the side of the rectangular tabletop 2 away from the operator. The back panel 6 is a sheet metal box structure, which is bolted to the rectangular tabletop 2 as a whole. The interior of the back panel 6 can be used to house auxiliary devices such as water pipes and vent hoods. In addition, the back panel 6 can also prevent oil splatter and keep the back wall clean.
[0040] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
