Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and more specifically, to an aviation water heater. Background Technology

[0002] Aviation water heaters are specially designed to meet the hot water needs inside aircraft. These heaters are typically installed in the aircraft's galley to provide food and drinking water, and the hot water supply usually uses an instantaneous water heater. However, in most existing water heaters, the inner tanks are completely interconnected. During hot water dispensing, cold water continuously enters the inner tank. Because the cold water carries a certain water pressure, and due to turbulence during flight, cold water entering from the bottom may surge to the top instantaneously. Since the temperature sensor in the inner tank can only detect the water temperature at a specific point, the outlet water temperature is unstable before the hot and cold water mixture temperature stabilizes. Furthermore, when a certain amount of cold water is injected and reaches the vicinity of the temperature sensor, it can cause the "heating" indicator light to illuminate. Although there is a temperature sensor for control, there is still a certain delay. Utility Model Content

[0003] The purpose of this invention is to provide an aviation water heater that can promote uniform mixing and heating of water in the inner tank, and deliver hot water at a constant temperature, thus avoiding unstable water temperature.

[0004] The embodiments of this utility model are achieved through the following technical solution: an aviation water heater, including an inner tank, an inlet at the bottom of the inner tank, an outlet and a temperature sensor at the top of the inner tank; at least one heating tube is provided in the inner tank and the heating tube is connected to the bottom of the inner tank; a baffle plate is provided inside the inner tank, and a water passage gap is left between the baffle plate and the inner wall of the inner tank.

[0005] Preferably, it also includes a water-blocking plate, which is disposed above and spaced apart from the baffle plate, and a water outlet is provided in the middle of the water-blocking plate; the heating pipe passes through the baffle plate and is connected to it.

[0006] Preferably, the heating tube has three tubes arranged close together and evenly spaced around the inner side of the water inlet; the heating tube is perpendicular to the bottom of the inner tank and the baffle plate.

[0007] Preferably, a baffle plate is installed at the top of the heating tube, and the baffle plate has several flow holes.

[0008] Preferably, the inner liner is provided with a water level gauge, which includes a guide rod and a float. The float is slidably connected to the guide rod, one end of the guide rod is connected to the bottom of the inner liner, and the other end of the guide rod is connected to the top of the inner liner.

[0009] Preferably, it also includes a base and a front panel, the inner liner is installed on the base, and the front panel is equipped with a water tap, which is connected to the water outlet.

[0010] Preferably, the water inlet is provided with a conical funnel on the side facing the inner liner.

[0011] The technical solution of the embodiments of this utility model has at least the following advantages and beneficial effects: By setting a baffle plate near the bottom, when cold water enters the inner tank, the baffle plate prevents the cold water from rushing directly to the outlet. While the outlet is discharging water, the inlet at the bottom of the inner tank continuously replenishes cold water. The cold water slowly enters the upper part of the inner tank along the edge of the baffle plate and mixes with the hot water. The mixing time is extended, and the hot water at the top can maintain a certain stable temperature output. Attached Figure Description

[0020] Example

[0021] The following description, in conjunction with specific embodiments, provides further details. Figures 1-3 As shown, this embodiment is an aviation water heater, including an inner tank 1. The bottom of the inner tank 1 is provided with a water inlet 12, and the top of the inner tank 1 is provided with a water outlet 11 and a temperature sensor 2. At least one heating tube 3 is provided in the inner tank 1, and the heating tube 3 is connected to the bottom of the inner tank 1. A baffle plate 4 is provided inside the inner tank 1, and a water passage gap 41 is left between the baffle plate 4 and the inner wall of the inner tank 1. Specifically, if the cold water added in through the water inlet 12 rises, it will be blocked by the baffle plate 4 to prevent it from rushing directly to the top and mixing with the hot water. Especially near the water outlet 11, when the cold water and hot water have not been completely mixed and reached a stable temperature, there will be alternating hot and cold water output. The baffle plate 4 and the water passage gap 41 allow the cold water to slowly rise from the bottom to the top and contact the hot water, delaying the mixing time. When the temperature sensor 2 at the top detects that the water temperature has dropped after being mixed evenly, the heating tube 3 is then energized to heat.

[0022] This embodiment also includes a water baffle plate 5, which is located above and spaced apart from the baffle plate 4. A water outlet 51 is opened in the middle of the water baffle plate 5. The heating pipe 3 passes through the baffle plate 4 and is connected to it. Specifically, when cold water enters the inner tank 1, it will first pass through the water baffle gap and then rise to the center through the water outlet 51, which prolongs the flow path of the cold water and reduces the flow speed of the water, which is conducive to the constant output temperature of hot water.

[0023] To ensure uniform heating of the water, the heating tube 3 is arranged in three closely spaced sections around the inside of the water inlet 51. The heating tube 3 is perpendicular to the bottom of the inner tank 1 and the baffle plate 4, and the height of the heating tube 3 is more than one-third of the height of the inner tank 1.

[0024] like Figure 1As shown, in order to increase the contact area between the heating tube 3 and the water and improve the heat conduction effect, a baffle plate 31 is installed at the top of the heating tube 3, and several flow holes 311 are opened on the baffle plate 31. The baffle plate 31 can further slow down the flow rate of the water rising from the water outlet 51, and the water is heated more quickly.

[0025] To prevent dry burning, a water level gauge 6 is installed inside the inner tank 1. The water level gauge 6 includes a guide rod 61 and a float 62. The float 62 is slidably connected to the guide rod 61. One end of the guide rod 61 is connected to the bottom of the inner tank 1, and the other end of the guide rod 61 is connected to the top of the inner tank 1. When the float 62 touches the bottom of the inner tank 1, it means that there is no water in the inner tank 1, and the heating tube 3 will stop heating the water. The heating tube 3 will only start heating when the float 62 touches the water and rises a certain distance along the guide rod 61.

[0026] This embodiment also includes a base 7 and a front panel 8. The inner tank 1 is installed on the base 7, and the front panel 8 is equipped with a water tap 9, which is connected to the water outlet 11. Specifically, by turning on the water tap 9, hot water can be gradually drawn out from the water outlet 11 at the top of the inner tank 1 for making coffee or beverages.

[0027] Reference Figure 1 and Figure 3 As shown, a conical funnel 121 is provided on the side of the water inlet 12 facing the inner tank 1; specifically, the bottom water inlet 12 is an oscillating water inlet, and the cold water generated by the Coanda effect at the water outlet 11 has a certain pressure and slowly oscillates in a fan shape into the inner tank 1, and the cold water pressurizes to push the hot water out.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
