[0009] The electric water heater with a warm air structure provided by the utility model has the following beneficial effects compared with the background technology:

[0010] The above-mentioned electric water heater with a warm air structure does not need to be remodeled in the bathroom by integrating the warm air function on the electric water heater, thereby effectively reducing the cost. By providing a downwardly protruding mounting portion on the outer cover of the control box fixedly connected to the outer shell cylinder, and by arranging the warm air component in the mounting portion, the warm air component can be effectively protected. Among them, the air entering from the air inlet is heated by the warm air component and then flows out from the air outlet, so that warm air circulates at the position below the electric water heater, thereby improving the comfort of users when bathing in winter. Specifically, the mounting portion is arranged in a downwardly protruding form, so that the mounting portion can avoid other structures on the outer cover of the control box, reducing the obstruction of other structures at the air outlet and the air inlet, and the warm air is more easily blown to the human body, thereby improving the air circulation effect and improving the user's bathing experience.

[0011] In one of the embodiments, the air outlet is provided on a first side surface of the mounting portion, and the first side surface is arranged at an angle to a horizontal plane.

[0012] By setting the first side surface where the air outlet is located at an angle to the horizontal plane, the warm air from the air outlet can be more easily blown to the bather, so that warm air can be used to assist when there is no hot water, thereby improving the comfort of bathing and increasing the utilization rate of warm air.

[0013] In one embodiment, the angle between the first side surface and the horizontal plane is between 110-180°.

[0014] The angle between the first side surface and the horizontal plane is set to 110-180 degrees. Such an angle range is more conducive to blowing warm air onto the bather.

[0015] In one of the embodiments, the air inlet is arranged on the second side surface of the mounting portion, the first side surface is adjacent to the second side surface, and the first side surface is arranged at an angle to the second side surface.

The fan is set at the installation part, and the air outlet of the fan is set toward the air outlet, so that the air entering from the air inlet is pressurized and accelerated by the fan and flows to the air outlet of the installation part. The heating element is set at the air outlet of the fan, so that the air flowing out of the air outlet of the fan can be directly heated by the heating element and then flow out from the air outlet, thereby reducing the flow path of the warm air, reducing heat loss, and effectively utilizing heat.

[0023] In one of the embodiments, the heating element is configured as a PTC heater.

[0024] The heating element is set as a PTC heater, which has the advantages of rapid heating, high thermal efficiency, health and environmental protection.

[0025] In one embodiment, the warm air component further includes:

[0026] A mounting plate is fixedly connected to the control box cover, and the fan and the heating element are both fixedly connected to the mounting plate.

[0027] By fixing the mounting plate to the outer cover of the control box, the fan and the heating element are fixedly connected to the mounting plate, so as to improve the integration of the air guide assembly, thereby facilitating the fixed connection of the heating element to the mounting portion. In addition, the mounting plate also reduces the risk of water leaking from the anti-electric wall and splashing onto the fan and the heating element, thereby damaging the fan and the heating element. Moreover, the mounting plate also guides the air, so that the wind entering the mounting portion from the air inlet is guided by the guide plate and then flows out from the air outlet, thereby improving the utilization rate of the wind.

[0028] In one of the embodiments, a water inlet pipe installation port and a water outlet pipe installation port are also provided on the outer cover of the control box, and the water inlet pipe installation port and the water outlet pipe installation port are located on a side of the installation plate away from the heater assembly.

[0029] The control box housing is provided with water inlet and outlet pipe installation openings to provide escape openings for the water inlet and outlet pipes, thereby facilitating the water inlet and outlet pipes to communicate with the outer shell body. The warm air assembly is arranged on the side of the mounting plate away from the water inlet and outlet pipe installation openings, so that the mounting plate can isolate the water outlet and inlet pipes from the warm air assembly, thereby facilitating the practical safety performance of the water heater and the life of the warm air assembly.

[0030] In one of the embodiments, the control box cover is fixedly connected to the outer shell cylinder through a mounting column, and the heater assembly is fixedly connected to the mounting portion through a mounting column.

[0046] See also Figures 1 to 6An embodiment of the utility model provides an electric water heater with a warm air structure, the electric water heater with a warm air structure comprises an outer shell cylinder 100, a control box outer cover 200 and a warm air assembly 300, the control box outer cover 200 is fixedly connected to the bottom of the outer shell cylinder 100, the control box outer cover 200 is constructed with a downwardly protruding mounting portion 210, the mounting portion 210 is provided with an air inlet 2121 and an air outlet 2111; the warm air assembly 300 is arranged at the mounting portion 210 in the control box outer cover 200, the air entering the control box outer cover 200 from the air inlet 2121 is heated by the warm air assembly 300, and then flows out from the air outlet 2111.

[0047] The electric water heater with a warm air structure described above does not need to be remodeled in the bathroom by integrating a warm air function on the electric water heater, thereby effectively reducing costs. By setting a downwardly protruding mounting portion 210 on the control box cover 200 fixedly connected to the shell cylinder 100, and by setting the warm air assembly 300 in the mounting portion 210, the warm air assembly can be effectively protected. Among them, the air entering from the air inlet 2121 is heated by the warm air assembly 300 and then flows out from the air outlet 2111, so that the position below the electric water heater has warm air circulation, thereby improving the comfort of users when bathing in winter. Specifically, the mounting portion 210 is set in a downwardly protruding form, so that the mounting portion 210 can avoid other structures on the control box cover 200, reducing the obstruction of other structures at the air outlet 2111 and the air inlet 2121, and the warm air is more likely to blow to the human body, thereby improving the air circulation effect and improving the user's bathing experience.

[0048] It is understandable that the outer shell cylinder 100 is used to accommodate the inner tank of the water heater to keep the hot water in the inner tank warm and protect the inner tank. The control box cover 200 is used to connect the control box with the outer shell cylinder 100 on the one hand, and to protect the control box on the other hand. In this embodiment, the space of the control box cover 200 is cleverly utilized, and the warm air assembly 300 is arranged in the control box cover 200, which not only saves the space of the entire electric water heater, but also enables the water heater to have the function of conveying warm air.

[0049] It should be noted that, in the present embodiment, the mounting portion 210 is a structure that protrudes downward, which means that after the electric water heater is installed on the wall, the mounting portion 210 protrudes downward relative to the remaining structure of the control box cover 200 .

[0050] like Figure 2 As shown, in one embodiment, the air outlet 2111 is provided on the first side surface 211 of the mounting portion 210, and the first side surface 211 is arranged at an angle with the horizontal plane. In this embodiment, the angle between the first side surface and the horizontal plane is as follows: Figure 2As shown, denoted by θ. By setting the first side surface 211 where the air outlet 2111 is located to be at an angle with the horizontal plane, the warm air from the air outlet 2111 is more easily blown to the bather, so that there is also warm air assistance when there is no hot water, thereby improving the comfort of bathing and the utilization rate of the warm air. Specifically, the angle between the first side surface 211 and the horizontal plane is between 110-180°. The angle between the first side surface 211 and the horizontal plane is set to 110-180°. Such an angle range is more conducive to blowing the warm air to the bather.

[0051] It is understandable that a portion of the first side surface 211 of the mounting portion 210 is configured as a hollow structure having a plurality of through holes penetrating the first side surface 211, and these through holes are the above-mentioned air outlets 2111. The extension direction of these through holes can be perpendicular to the first side surface 211, or can have a certain inclination angle with the first side surface 211.

[0052] In one embodiment, the air inlet 2121 is disposed on the second side surface 212 of the mounting portion 210, the first side surface 211 and the second side surface 212 are adjacent, and the first side surface 211 and the second side surface 212 are disposed at an angle. In this embodiment, the angle between the first side surface 211 and the second side surface 212 is as follows: Figure 2 As shown, denoted by α, the first side surface 211 and the second side surface 212 are arranged at an angle so that the air inlet 2121 and the air outlet 2111 can convect smoothly, thereby ensuring the air inlet and air outlet volume. The first side surface 211 and the second side surface 212 are perpendicular to each other. The first side surface 211 and the second side surface 212 are arranged in a perpendicular form so that there is a better air convection effect between the air inlet and the air outlet 2111. Specifically, a part of the area on the second side surface 212 is arranged to have a plurality of through holes penetrating the second side surface 212, and these through holes constitute the above-mentioned air inlet 2121.

[0053] like Figure 3 and Figure 5As shown, in one embodiment, the warm air assembly 300 includes a fan 310 and a heating element 320. The fan 310 is arranged at the mounting portion 210, and the air outlet end of the fan 310 is arranged toward the air outlet 2111; the fan 310 is arranged at the air inlet 2121; the heating element 320 is fixedly connected to the fan 310, and the heating element 320 is arranged at the air outlet end of the fan 310. The fan 310 is used to pressurize and accelerate the air entering the mounting portion 210 through the air inlet 2121 and then transport it to the heating element 320, and the heating element 320 is used to heat the air. The fan 310 is arranged at the mounting portion 210, and the air outlet end of the fan 310 is arranged toward the air outlet 2111, so that the air entering from the air inlet 2121 flows to the air outlet 2111 of the mounting portion 210 after being pressurized and accelerated by the fan 310. The heating element 320 is arranged at the air outlet end of the fan 310 so that the air flowing out of the air outlet end of the fan 310 can be directly discharged from the air outlet 2111 after being heated by the heating element 320, thereby reducing the flow path of the warm air and effectively utilizing the heat with less heat loss.

[0054] In the present embodiment, the heating element 320 is configured as a PTC heater 322. The PTC heater 322 has the advantages of rapid heating, high thermal efficiency, and health and environmental protection. Moreover, by adopting the PTC heater 322, the warm air component 300 can automatically adjust the heating power and the air volume of the fan according to the temperature to prevent the hot water from overheating and scalding the user or the air volume from being too small and burning the fan. Specifically, the heating element 320 has a support frame 321, and the support frame 321 is a square shell structure with both ends open, and the PTC heater 322 is arranged in the support frame 321. The support frame 321 is fixedly connected to the shell of the fan 310.

[0055] like Figure 6 As shown, in one embodiment, the warm air assembly 300 also includes a mounting plate 330, the mounting plate 330 is fixedly connected to the control box housing 200, and the fan 310 and the heating element 320 are both fixedly connected to the mounting plate 330. By fixing the mounting plate 330 on the control box housing 200, the fan 310 and the heating element 320 are fixedly connected to the mounting plate 330 to improve the integration of the air guide assembly, so as to facilitate the fixed connection of the warm air assembly 300 with the mounting portion 210. In addition, the mounting plate 330 also has the function of reducing the risk of water leaking from the anti-electric wall and splashing on the fan 310 and the heating element, damaging the fan 310 and the heating element. Moreover, the mounting plate 330 also has the function of guiding the air, so as to facilitate the wind entering the mounting portion 210 from the air inlet 2121 to flow out from the air outlet 2111 after being guided by the guide plate, thereby improving the utilization rate of the wind.

[0056] like Figure 6As shown, specifically, the mounting plate 330 is configured to be a substantially V-shaped structure, one end of the mounting plate 330 is fixedly connected to the end of the first side plate, and the other end of the mounting plate 330 is fixedly connected to the end of the second side plate, so as to prevent the water inlet pipe and the water outlet pipe from being isolated in another space of the control box housing 200. The mounting plate 330 is configured to be a V-shaped structure so that the air flow direction can be guided by the inclined surface of the V-shaped structure.

[0057] like Figure 4 and Figure 6 As shown, in one embodiment, the control box housing 200 is further provided with a water inlet pipe installation port 220 and a water outlet pipe installation port 230, and the water inlet pipe installation port 220 and the water outlet pipe installation port 230 are located on the side of the mounting plate 330 away from the warm air assembly 300. The water inlet and outlet pipe installation ports 230 are provided on the control box housing 200 to provide a evacuation port for the water inlet pipe and the water outlet pipe, so that the water inlet pipe and the water outlet pipe are connected to the outer shell cylinder 100. The warm air assembly 300 is provided on the side of the mounting plate 330 away from the water inlet and outlet pipe installation ports 230, so that the mounting plate 330 can isolate the water outlet pipe and the water inlet pipe from the warm air assembly 300, thereby facilitating the practical safety performance of the water heater and the life of the warm air assembly 300.

[0058] In one embodiment, the control box cover 200 is fixedly connected to the outer shell body 100 through the mounting post, and the heating assembly 300 is fixedly connected to the mounting portion 210 through the mounting post. The control box cover 200 is fixedly connected to the outer shell body 100 through the mounting post, which is convenient for disassembly and assembly, thereby facilitating maintenance; and the heating assembly 300 is also fixedly connected to the mounting portion 210 through the mounting portion 210, which also has the advantage of being convenient for disassembly and assembly, thereby facilitating maintenance.

[0059] Specifically, the mounting post can be a bolt or a screw, and of course also a dedicated mounting fastener. In the present embodiment, the control box cover 200 is fixedly connected with the shell cylinder 100 by bolts, and the mounting plate 330 is also fixedly connected with the control box cover 200 by bolts.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
