Referring to fig. 1 to 7, the present invention provides a heating device for preventing water from returning, which comprises a heating pot assembly 1 and a three-way box assembly 2. Wherein the heating pan component 1 comprises a heating pan 11 for heating water; the three-way box assembly 2 comprises a three-way box 21, the three-way box 21 comprises an inner cavity 211 communicated with the heating pot 11 and an outer cavity 212 communicated with the water tank 3, and the outer cavity 212 is communicated with the inner cavity 211 so that water in the water tank 3 sequentially enters the heating pot 11 through the outer cavity 212 and the inner cavity 211; an air pipe 4 for air to flow between the tee box 21 and the heating pot 11 is also arranged between the tee box 21 and the heating pot 11.

Referring to fig. 2, the heating pan assembly 1 includes the heating pan 11. The bottom of the heating pot 11 is arranged in the heating pot bottom cover 13, a cavity 131 is formed in the heating pot bottom cover 13, the bottom of the heating pot is placed in the cavity 131, and the heating pot sealing ring 12 is matched to seal the cavity 131. Specifically, the heating pan 11 includes a heating pan bottom plate 111 and a heating pan cover 112 covering the heating pan bottom plate 111. A heating cavity for containing water and water vapor is formed between the heating pan cover 112 and the heating pan bottom plate 111, and a heating structure 113 protruding in the heating cavity is arranged in the center of the heating pan bottom plate 111. Preferably, referring to fig. 3, the heating structure 113 is a pillar structure. The heating structure 113 includes a heat conductive case 1131 and a heating wire (not shown) wrapped inside the heat conductive case 1131. Preferably, the protrusion 1132 protrudes from the outer surface of the heat conducting shell 1131 to increase the surface area of the heat conducting shell 1131, so as to increase the contact area between the heating structure 113 and water, thereby increasing the heating efficiency of water.

The water in the water tank 3 enters the heating pot 11 through the three-way box assembly 2, is positioned on the heating pot bottom plate 111 due to the action of gravity, and is accumulated around the heating structure 113 due to the limit of the heating pot cover 112. The water level in the heating pan 11 is defined as a distance from the water level in the heating pan 11 in the height direction of the heating pan cover 11 to the heating pan bottom plate 111 in fig. 2 with the heating pan bottom plate 111 as a reference object. The water level in the heating pan 11 can not be higher than the highest position of the heating structure 113 all the time, so as to ensure that all the water is heated by the heating structure 113 in the space defined by the heating structure 113 and the heating pan cover 112, and simultaneously ensure that the water vapor formed in the heating cavity of the heating pan 11 has enough flowing space. In the initial state, the heating structure 113 in the heating pan 11 is not yet turned on, that is, the water in the heating pan 11 is not heated to form water vapor at this time, as the heating structure 113 is turned on to heat, the water in the heating pan 11 is gradually heated to form water vapor, the water in the heating pan 11 is gradually reduced, and then the water replenished into the heating pan 11 is continuously evaporated to form water vapor, so that the liquid level in the subsequent heating pan 11 is lower than the initial liquid level in the heating pan 11 in the initial state.

Referring to fig. 2, one end of the air tube 4 is connected to the heating pot cover 112. Preferably, the connection position of the air pipe 4 and the heat-generating pot cover 112 is higher than the initial liquid level of the heat-generating pot 11 by at least 40 mm. By the arrangement, even in the initial state, water in the heating pan 11 collides with each other and cannot reach the air pipe 4, so that liquid water is prevented from flowing into the three-way box assembly 2 from the air pipe 4. It should be noted that the heating pan 11 is communicated with the three-way box 21, and according to the principle of the communicating vessel, the liquid level of the heating pan 11 and the liquid level in the three-way box 21 are located at the same horizontal line, so the initial liquid level of the heating pan 11 is related to the initial liquid level of the three-way box 21.

Referring to fig. 4, the tee box assembly 2 includes a tee box 21. The three-way box 21 is located below the water tank 3 and connected to the water tank 3. Specifically, referring to fig. 6, the garment steamer is provided with a base 6 having a base shell 61, and the heating pan assembly 1 and the three-way box assembly 2 are wrapped in the base shell 61. The base case 61 forms an open-type cavity 611, and the cavity 611 receives the water tank 3. Namely, a concave cavity wall 612 is arranged between the heating pan assembly 1 and the three-way box assembly 2 and the water tank 3. Alternatively, the heating pan assembly 1 and the three-way box assembly 2 are located inside the cavity wall 612, and the water tank 3 is located outside the cavity wall 612. Referring to fig. 4, 5 and 6, the three-way box 21 further forms an opening 213, and the cavity 611 forms a protrusion 614 matching the shape of the opening towards a cavity wall 612 on one side of the three-way box 21, and the protrusion 614 is snapped into the opening 213. The three-way box assembly 2 is further provided with a three-way box sealing ring 22 for sealing the clamping position of the cavity wall 612 and the opening 213. The cavity wall 612 is provided with a circular hole 613 at the protrusion 614, and the water outlet 31 of the water tank 3 extends out from the circular hole 613 to be communicated with the three-way box 21.

The three-way box 21 includes an inner chamber 211 communicating with the heating pan 11 and an outer chamber 212 connected with the water tank 3, and the outer chamber 212 communicates with the inner chamber 211. Specifically, the position of the circular hole 613 corresponds to the outer cavity 212, and the water outlet 31 of the water tank 3 extends out of the circular hole 613 to be communicated with the three-way box 21. The water in the water tank 3 enters the outer cavity 212 of the three-way box 21 through the water outlet 31, then the water enters the inner cavity 211 again, and then enters the heating pot 11 from the inner cavity 211, so the three-way box 21 and the heating pot 11 form a communicating vessel, according to the communicating vessel principle, the liquid level of the heating pot 11 and the liquid level of the three-way box 21 are positioned on the same horizontal line, and therefore the liquid level of the heating pot 11 is in direct proportion to the liquid level of the three-way box 21.

Referring to fig. 4, 5 and 6, the air tube 4 is communicated with the inner cavity 211 of the three-way box 21. Preferably, the connection between the trachea 4 and the lumen 211 is provided in the lumen 211 adjacent the opening 213. This is because, referring to fig. 5, in the tee box 21, water sinks below due to gravity, water vapor is located above the tee box 21, and the communication position of the air tube 4 in the inner cavity 211 is opened at the position of the inner cavity 211 close to the opening 213, that is, above the tee box 21, so as to prevent the water in the tee box 21 from entering the air tube 4, and ensure that the two ends of the air tube 4 are connected to each other and are all at the air flowing position. Specifically, the communication between the air tube 4 and the inner cavity 211 is disposed above the highest liquid level of the inner cavity 211. The maximum liquid level of the three-way cartridge 21 is determined by the regulating cylinder 23 of the outer chamber 212. Specifically, the height of the highest liquid level of the three-way box 21 relative to the bottom surface of the three-way box 21 is equal to the height of the highest point of the adjusting column 23 relative to the bottom surface of the three-way box 21. The structure and principle are commonly found in humidifiers and ironing machines, and are common technical means, which are not described herein. Therefore, the communication position of the air pipe 4 and the three-way box 21 is arranged between the highest liquid level and the bulge 614, so that water in the three-way box 21 can be effectively prevented from entering the heating pot 11 through the air pipe 4, and the two ends of the air pipe 4 are both connected to form an air flowing position.

This is because, when the water inlet 114 is located below the entire heating pan 11, the height of the water inlet 114 is made lower, so that water splash is not easily splashed when water enters the water inlet 114, and noise is reduced.

Referring to fig. 7, the present invention preferably arranges the water inlet 114 at the bottom plate 111 of the heating pan. Further, the water inlet 114 is disposed at one side of the heating structure 113 of the heat-generating pot base plate 111. Preferably, the inner cavity 211 of the three-way box 21 is connected with the water inlet 114 through the water pipe 5.

Specifically, referring to fig. 2, 3 and 7, the bottom cover 13 of the heating pan is provided with a cavity 131, a section of the water pipe 5 corresponding to the water inlet 114 is further disposed in the cavity 131, which is defined as a first section 51, the first section 51 has an upward opening, i.e., facing the direction of the water inlet 114, and the first section 51 is perpendicular to the bottom plate 111 of the heating pan, i.e., in a vertical direction. Accordingly, the heating pan sealing ring 12 protrudes inward to form a sealing tube 121 to seal the contact of the water inlet 114 and the opening of the first section 51. The other section of the water pipe 5 extends from the first section 51 to the bottom of the inner cavity 211 of the three-way box 21 to ensure that the water in the inner cavity 211 can enter the water pipe 5. referring to fig. 7, after the water in the water tank 3 enters the three-way box 21 and enters the water pipe 5 from the inner cavity 211, the water passes through the first section 51 perpendicular to the bottom plate 111 of the heating pan and then enters the heating pan 11 through the water inlet 114 in a vertical upward direction. By adopting the structure that the water inlet 114 is arranged on the heating pan bottom plate 111, water can enter the heating pan 11 through the water inlet 114 in the vertical upward direction at the first section 51 of the water pipe 5, the water entering direction is the direction of the counter gravity, namely, the water needs to overcome the gravity of the water in the entering process, so that the water entering speed is slow, and the probability of water sputtering is reduced.

In addition, please refer to fig. 5, in the three-way box 21 provided by the present invention, the outer cavity 212 of the three-way box 21 is connected to the water tank 3, that is, the water in the water tank 3 enters the outer cavity 212 of the three-way box 21. preferably, a one-way valve 23 is disposed in the outer cavity 212 of the three-way box 21, one side of the one-way valve 23 is communicated with the inner cavity 211, and the other side is communicated with the water tank 3, so that the water in the water tank 3 enters the other side of the one-way valve 23 in the outer cavity 212, when the water at the other side enters the side communicated with the inner cavity 211 through the one-way valve 23, the water cannot flow backwards, that is, the water cannot flow backwards to the water tank 3.
