[0030] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0031] Example 1

[0032] refer to Figure 1-8 The present embodiment provides a water tank device with integrated heat dissipation duct, including a water tank fixing box 1 and a water tank assembly 2, wherein the water tank fixing box 1 is provided with an installation cavity 101 opening forward and a heat dissipation duct 102 located at the bottom of the installation cavity 101. In the present embodiment, the bottom of the heat dissipation duct 102 is opened to form a bottom opening, and the front and rear ends of the heat dissipation duct 102 are opened to form an air inlet and an air outlet, respectively. The water tank assembly 2 is detachably installed in the installation cavity 101 from the front to the back. Therefore, by integrating the heat dissipation duct 102 on the water tank fixing box 1 with the installation cavity 101, it is possible to reduce the number of parts required for assembly, reduce manufacturing costs, and improve assembly efficiency. At the same time, the water tank assembly 2 can be used to cool the hot air flow in the heat dissipation duct 102, so as to preheat the water in the water tank assembly 2 and improve the utilization rate of the hot air path.

[0033] Furthermore, the water tank device further comprises a fan assembly 3 and / or a circuit board 4. The fan assembly 3 is mounted on the water tank fixing box 1 and is located behind the water tank assembly 2. The air outlet of the fan assembly 3 is connected to the inlet of the heat dissipation duct 102. The circuit board 4 is mounted on the water tank fixing box 1. The circuit board 4 is located above the heat dissipation duct 102 and is arranged close to the water tank assembly 2. Thus, the circuit board 4 can isolate the extra unnecessary heat generated by most cooking equipment (such as a steam oven) during operation. Since the circuit board 4 is arranged close to the water tank assembly 2, the heat generated by the circuit board 4 during operation can be partially taken away by the fan assembly 3 in the form of heat convection, and can also be absorbed by the water tank assembly 2 in the form of heat conduction and heat radiation, which is beneficial to prolonging the service life of the circuit board 4.

[0034] In this embodiment, the installation cavity 101 and the water tank assembly 2 are both in a "U" shape, and a receiving cavity 103 located above the heat dissipation duct 102 is provided on the top of the water tank fixing box 1. The installation cavity 101 is located at the periphery of the receiving cavity 103, and the circuit board 4 is installed in the receiving cavity 103, so that the three adjacent surfaces of the circuit board 4 and the receiving cavity 103 are close to the water tank assembly 2, that is, the rear end of the water tank assembly 2 surrounds the circuit board 4 and the receiving cavity 103, which is conducive to further improving the heat dissipation effect of the water tank assembly 2 on the circuit board 4. In other embodiments, the installation cavity 101 and the water tank assembly 2 can be designed to be in an "L" shape, in which case the rear end of the water tank assembly 2 will surround the two adjacent surfaces of the receiving cavity 103 and the circuit board 4.

[0035] refer to Figure 3-8 A positioning structure and / or a reinforcing structure is provided between the water tank assembly 2 and the installation cavity 101. The positioning structure includes a positioning protrusion 111 and a positioning slot 211. A positioning slot 211 is provided at the bottom of the water tank assembly 2 and is recessed toward the inside of the water tank assembly 2. A positioning protrusion 111 extending upward is provided at the bottom of the installation cavity 101. The positioning protrusion 111 is engaged with the positioning slot 211 to achieve reliable positioning and fixing of the water tank assembly 2 in the installation cavity 101 of the water tank fixing box 1. The reinforcement structure includes a first reinforcement portion 121 and / or a second reinforcement portion 212. The first reinforcement portion 121 is arranged on the bottom surface or the top surface of the installation cavity 101 to strengthen the strength of the water tank fixing box 1 and reduce the contact area between the water tank assembly 2 and the bottom surface or the top surface of the installation cavity; the second reinforcement portion 212 is arranged on the bottom or the top of the water tank assembly 2 to strengthen the strength of the water tank assembly 2 and reduce the contact area between the water tank assembly 2 and the bottom surface or the top surface of the installation cavity.

[0036] refer to Figure 3-8 A gripping portion 213 is provided at the front end of the water tank assembly 2, so that the water tank assembly 2 can be pushed into or pulled out of the installation cavity 101 of the water tank fixing box 1 through the gripping portion 213. A water suction nozzle 23 is provided on the rear side wall of the right end of the water tank assembly 2, and a water receiving nozzle 112 is provided at a position of the rear cavity wall of the installation cavity 101 corresponding to the water suction nozzle 23, and the water receiving nozzle 112 can be connected to the inside of the water tank assembly 2 through the water suction nozzle 23.

[0037] In this embodiment, the water tank assembly 2 is in a "U" shape, and a plurality of water flow buffer portions 214 arranged in an alternating manner are provided inside the water tank assembly 2. In this way, when the water tank assembly 2 filled with water is quickly pushed into the water tank fixing box 1, the water flow buffer portion 214 can weaken the momentum influence of the water flow, weaken the water flow wave effect caused by the sudden change in shape of the end of the water tank assembly 2, and prevent the water in the water tank assembly 2 from overflowing and affecting the circuit board 4.

[0038] Specifically, the water tank assembly 2 includes a water tank body 21 and a box water tank cover 22. The water tank body 21 has a water storage tank (not shown in the figure) that opens upward. A positioning card slot 211 that is recessed toward the inside of the water storage tank is provided at the bottom of the water tank body 21. A second reinforcing portion 212 is provided at the bottom of the water tank body 21. The second reinforcing portion 212 is composed of a plurality of reinforcing ribs arranged crosswise, so as to increase the strength of the water tank body 21 itself through the second reinforcing portion 212, and reduce the contact area between the water tank assembly 2 and the bottom surface of the installation cavity 101, so that the water tank assembly 2 is not easy to automatically slide out of the installation cavity. A gripping portion 213 is provided at the front end of the water tank body 21, and a "U"-shaped air avoidance portion (not shown in the figure) is formed at the rear end of the water tank body 21; and a plurality of staggered water flow buffer portions 214 are provided on the left and right sides of the rear end of the water storage tank.

[0039] The water tank cover 22 is sealed and connected to the top of the water tank body 21, and covers the upward opening of the water tank. A water inlet 221 connected to the water tank is provided on the water tank cover 22, and a water inlet cover 24 for opening or closing the water inlet 221 is provided on the water tank cover 22. The water suction nozzle 23 is arranged on the right side of the rear end of the water tank body 21, and one end thereof is connected to the water tank of the water tank body 21, and the other end is selectively connected to the water receiving nozzle 112 of the water tank fixing box 1.

[0040] refer to Figure 5-6 At least one of a guide portion, a flow stabilizing rib 113 and a flow diverting rib 114 is provided on the top surface of the heat dissipation duct 102. In this embodiment, the top surface of the heat dissipation duct 102 includes a high plane 1021, a gently sloping surface 1022 and a low plane 1023 connected in sequence from back to front, the low plane 1023 is lower than the high plane 1021, the gently sloping surface 1022 is any one of an inclined surface, an arc surface or a wave surface, and the guide portion is composed of the gently sloping surface 1022, which is used to quickly guide the airflow on the high plane 1021 to the low plane 1023.

[0041] The flow stabilizing rib 113 is arranged at the rear end of the low plane 1023 and is arranged close to the fan assembly 3. The upper end of the flow stabilizing rib 113 is integrally formed with the top surface of the heat dissipation duct 102, and the lower end is flush with the bottom of the water tank fixing box 1. Specifically, the flow stabilizing rib 113 includes a plurality of first fins arranged at intervals along the left and right directions, the first fins are in a straight line shape, and a flow stabilizing channel for airflow to pass through is formed between adjacent first fins. Therefore, by setting the flow stabilizing rib 113, when the airflow generated by the fan assembly 3 flows rapidly from the side of the flow stabilizing rib 113, the effects of diversion, stabilization, noise reduction and lowering the airflow temperature are achieved.

[0042] The diverter rib 114 is arranged at the front end of the low plane 1023 and is arranged away from the fan assembly 3. The upper end of the diverter rib 114 is integrally formed with the top surface of the heat dissipation duct 102, and the lower end is flush with the bottom of the water tank fixing box 1. Specifically, the diverter rib 114 includes at least two second fins that are open to the front and are in a "V" shape. The two second fins are respectively arranged on the left and right sides of the front end of the low plane 1023. The diverter rib 114 also includes a third fin group in an inverted "eight" shape, and the third fin group is arranged between the two second fins. Therefore, by setting the diverter rib 114, when the airflow generated by the fan assembly 3 flows rapidly from the side of the diverter rib 114, the pressure at the diverter rib 114 is low, which facilitates the rapid discharge of the airflow out of the heat dissipation duct 102.

[0043] refer to Figure 1-2 , further comprising a switch assembly 5, a support 115 extending outward is provided on the left side wall of the water tank fixing box 1, and a side opening 116 is provided at the position of the side wall of the installation cavity 101 corresponding to the support 115. The switch assembly 5 is detachably mounted on the top of the support 115, and the triggering part of the switch assembly 5 extends into the installation cavity 101 through the side opening 116, and is used to abut against the water tank assembly 2, so as to accurately detect whether the water tank assembly 2 is installed in place through the contact signal between the triggering part of the switch assembly 5 and the water tank assembly 2.

[0044] refer to Figure 1-4 Furthermore, a steam air inlet nozzle 117 is provided at the front end of the right side wall of the water tank fixing box 1, and a steam diverter groove 118 opening forward is provided at the position of the heat dissipation air duct 102 corresponding to the steam air inlet nozzle 117, and the steam diverter groove 118 is connected with the steam air inlet nozzle 117. Therefore, by moving the steam air inlet nozzle 117 and the steam diverter groove 118 forward, the influence of the heat generated by the steam liquefaction on the temperature rise of the whole machine is reduced, and the utilization rate of the heat dissipation air flow is improved. When the cooking device is working, the steam enters the steam diverter groove 118 from the steam air inlet nozzle 117, and the airflow generated by the fan assembly 3 passes through the flow stabilizing rib 113 and the diverter rib 114 in turn, and then flows rapidly beside the diverter rib 114, so that the pressure at the diverter rib 114 is low, while the pressure at the steam air inlet nozzle 117 and the steam diverter groove 118 is high, so that under the action of the pressure difference, the steam is quickly discharged outward.

[0045] refer to Figure 1-6The water tank fixing box 1 includes a water tank fixing seat 11 and an upper cover plate 12. The water tank fixing seat 11 is provided with an upwardly opening mounting groove (not shown in the figure), a heat dissipation duct 102 and a receiving cavity 103. The mounting groove is "U"-shaped. The heat dissipation duct 102 is located at the bottom of the mounting groove. The receiving cavity 103 is located at the rear end of the mounting groove and is surrounded by the "U"-shaped mounting groove. The upper cover 12 is "U"-shaped and can be detachably mounted on the top of the water tank fixing seat 11 and covers the upward opening of the mounting groove. An installation cavity 101 is formed between the upper cover 12 and the U-shaped mounting groove of the water tank fixing seat 11. In the present embodiment, the upper cover 12 and the water tank fixing seat 11 are detachably connected by a snap-fit ​​structure. The snap-fit ​​structure includes a hook 110. A plurality of hooks 110 extending upward are circumferentially spaced at the upper end of the mounting groove of the water tank fixing seat 11. Notches 120 for the hooks to pass through are provided at positions of the upper cover 12 corresponding to the hooks. During installation, each hook 110 passes through the corresponding notch 120 and hooks the top surface of the upper cover 12, so as to reliably limit and fix the upper cover 12 on the top of the water tank fixing seat 11.

[0046] The water tank assembly 2 is disposed in the installation cavity 101 and is detachably connected to the water tank fixing seat 11 and / or the upper cover plate 12. In this embodiment, the water tank assembly 2 is detachably connected to the water tank fixing seat 11 through a positioning structure. The fan assembly 3 is detachably installed at the rear end of the water tank fixing seat 11. The circuit board 4 is installed on the top of the water tank fixing seat 11 and is surrounded by a "U"-shaped installation groove.
