For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0037] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 3 As shown, a warm air structure is provided, which mainly includes: a warm air housing 1, a warm air component 2 and a swing blade mechanism 3.

[0038] The warm air structure described in this embodiment is mainly used for electric water heaters. It can adjust the outlet direction of the warm air to meet the needs of users of different heights and has a good heating effect.

[0039] Further, the warm air housing 1 is provided with an air outlet 101. The warm air assembly 2 is arranged in the warm air housing 1, and is used to generate warm air and blow the warm air out from the air outlet 101. The warm air assembly 2 includes a fan 201, a heater 202 and an air guide plate 203. The fan 201 is arranged in the warm air housing 1 and is located on a side away from the air outlet 101. The air guide plate 203 is detachably arranged in the warm air housing 1, the air outlet of the air guide plate 203 faces the air outlet 101, and the air inlet of the air guide plate 203 faces the fan 201. The heater 202 is arranged in the air guide plate 203. The fan 201 inhales external air from the air inlet 102 and blows it to the air guide plate 203. The air guide plate 203 guides the air flow to the heater 202, and after being heated by the heater 202, it is blown out from the air outlet 101 to form warm air at the air outlet 101.

[0040] The swing blade mechanism 3 is arranged outside the air outlet 101 and is rotatably connected to the air guide plate 203. When the swing blade mechanism 3 rotates relative to the air guide plate 203, the relative position of the swing blade mechanism 3 and the air outlet 101 can be changed to control the direction of the warm air at the air outlet 101.

[0041] It can be seen that the warm air structure provided in the embodiment of the present application uses the warm air component 2 in the warm air housing 1 to form warm air and send it out from the air outlet 101 to achieve the heating function, so that the user can use the electric water heater more comfortably. The swing blade mechanism 3 at the air outlet 101 rotates relative to the air guide plate 203 to adjust the direction of the warm air at the air outlet 101, so that users of different heights can obtain warm air according to their needs, thereby improving the compatibility of the warm air structure, having a good heating effect, and providing a better user experience.

[0042] It is understandable that when the warm air structure is applied to the water heater, the warm air structure is installed on the outer shell of the water heater. Due to the limitations of the installation environment, there is a certain distance between the fan 201 and the air outlet 101. By setting the air guide plate 203, the air guide plate 203 guides the airflow so that the warm air can be blown out from the air outlet 101 faster and better.

[0043] In addition, the fan 201 and the heater 202 are separately arranged on opposite sides of the warm air housing 1. Compared with the traditional structure in which the fan 201 and the heater 202 are integrated, the warm air structure provided by the embodiment of the present application occupies less space, is convenient to install and use, and is more beautiful.

[0044] Specifically, Figure 3 and Figure 4 As shown, the air outlet 101 is arranged on the side of the heater housing 1 and extends along the length direction of the heater housing 1 to expand the air outlet range. Figure 2 As shown by arrow A in FIG. Further, the air outlet 101 is arranged at the lower side of the warm air housing 1 so as to blow toward the user.

[0045] In addition, air inlets 102 are provided at opposite ends of the bottom surface of the heater housing 1. The air inlet 102 has a plurality of openings, which are arranged at intervals along the width direction of the heater housing 1, and each opening extends along the length direction of the heater housing 1. Figure 2 As shown by arrow B in FIG. External air enters the heater housing 1 from the air inlet 102 , is heated by the heater assembly 2 , and then blows out from the air outlet 101 .

[0046] It should be noted that the embodiment of the present application does not limit the swing blade mechanism 3 , as long as the swing blade mechanism 3 can adjust the warm air direction of the air outlet 101 .

[0047] In one embodiment, Figure 2 and Figure 4 As shown, the swing blade mechanism 3 includes: a swing blade body 301. The swing blade body 301 is rotatably arranged on one side of the air outlet 101 along the length direction of the air guide plate 203. The length direction of the air guide plate 203 is consistent with the length direction of the warm air housing 1. By rotating the swing blade body 301, the warm air direction is adjusted. The length of the swing blade body 301 matches the length of the air outlet 101, so as to control the warm air direction at the air outlet 101 to the greatest extent and evenly.

[0048] It should be noted that the rotation form of the swing blade body 301 provided in the embodiment of the present application can be manual as needed, which has a lower cost, or automatic to improve the degree of automation and facilitate use.

[0049] Compared with the manual mode, the automatic mode can further improve the user experience. Figure 4 and Figure 6 As shown, the swing blade mechanism 3 also includes a driving member 302. The driving member 302 is disposed on the heater housing 1 and connected to the swing blade body 301 through a transmission member. The driving member 302 is suitable for driving the swing blade body 301 to rotate relative to the air outlet 101 to automatically adjust the air outlet direction of the air outlet 101.

[0050] Specifically, the driving member 302 and the transmission member can adopt any existing structure. For example, the driving member 302 adopts a driving motor or a driving motor, and the transmission member adopts a rotating shaft, etc. The driving motor can be fixed in the warm air housing 1 through a mounting seat. The rotating shaft is fixedly connected to one side of the swing blade body 301 in the width direction. The output shaft of the driving motor is connected to the rotating shaft to drive the swing blade body 301 to swing through the rotating shaft. The self-locking characteristics of the driving motor can also be used to fix the position of the swing blade body 301 after the driving motor stops, so as to achieve directional blowing of warm air.

[0051] In one embodiment, the warm air structure further includes a controller and an operation module. The controller is electrically connected to the drive motor and the operation module, respectively. The user sends an adjustment instruction to the controller through the operation module, and the controller controls the drive motor based on the adjustment instruction. The operation module can use conventional operation modules such as buttons and knobs. For example, the operation module includes a forward button and a reverse button. The user presses the forward button to control the drive motor to rotate forward and drive the swing blade body 301 to rotate clockwise, or the user presses the reverse button to control the drive motor to reverse and drive the swing blade body 301 to rotate counterclockwise.

[0052] It should be noted that the controller can select any existing controller as needed. For example, the controller can select an existing controller such as a microcontroller unit (MCU), a central processing unit, an electronic controller unit (ECU), etc. Of course, other conventional controllers can also be selected as needed. This is not limited in the embodiments of the present application.

[0053] In some other embodiments, the swing blade mechanism 3 may also adopt other conventional structures, for example, the swing blade mechanism 3 is a plurality of synchronously swinging baffles, and the plurality of baffles are arranged at the air outlet 101. In this regard, the embodiments of the present application do not impose too many restrictions.

[0054] It should be noted that the embodiment of the present application does not limit the structure of the warm air component 2 , as long as the warm air component 2 can generate warm air and send the warm air out from the air outlet 101 .

[0055] Exemplarily, in order to improve the air outlet effect of the warm air component 2, the fan 201 can adopt a crossflow fan. The crossflow fan includes a motor and a crossflow fan. The output shaft of the motor is connected to the crossflow fan, drives the crossflow fan to rotate, and generates an airflow blowing toward the heater 202. The motor and the crossflow fan are respectively fixed to the inner bottom surface of the warm air housing 1 by fasteners. The heater 202 can adopt a PTC (Positive Temperature Coefficient) heater. The PTC heater has stable resistance, high safety, small size, and easy installation.

[0056] It is understandable that in some other embodiments, the fan 201 and the heater 202 may also adopt any other conventional structures, and the embodiments of the present application do not impose too many limitations on this.

[0057] When the air outlet 101 is blocked or the heater 202 is abnormal, there is a problem that the temperature of the warm air at the air outlet 101 rises suddenly, and the excessively high temperature of the warm air can easily burn the user.

[0058] In order to prevent the warm air from being too hot at the air outlet 101 and scalding the user, in one embodiment, Figure 2 , Figure 4 and Figure 5As shown, the warm air structure also includes a thermostat 4. The thermostat 4 is arranged on the air guide plate 203 and is electrically connected to the heater 202. The thermostat 4 selects a preset control temperature in advance, and when it is detected that the temperature reaches the preset control temperature, the heater 202 is controlled to be powered off to improve the safety and stability of the warm air structure. In order to facilitate the thermostat 4 to detect the warm air temperature, the thermostat 4 is arranged at a distance of about 5 mm from the air guide plate 203 to the heater 202. The thermostat 4 can adopt conventional thermostats such as a sudden jump thermostat and a liquid expansion thermostat.

[0059] Furthermore, in one embodiment, the heating structure further includes an alarm, which is electrically connected to the thermostat 4. When the temperature reaches a preset control temperature, the alarm sounds to remind the user to perform maintenance in time. For example, the alarm is a buzzer, which sounds when the temperature reaches a preset control temperature.

[0060] Further, in one embodiment, if Figure 4 As shown, the air guide plate 203 is connected to the heater housing 1 by means of a buckle and fixed by means of a fastener. Specifically, the inner bottom surface of the heater housing 1 is provided with an inclined surface inclined toward the fan 201 assembly. The air guide plate 203 is first connected to the inclined surface of the heater housing 1 by means of six sets of buckles, and then fixed to the inclined surface of the heater housing 1 by means of three sets of fasteners. The fasteners can be a plurality of screws, and a plurality of screw holes are correspondingly provided on the heater housing 1, so that the structure is simple and installation is convenient.

[0061] Furthermore, in one embodiment, one side of the swing blade body 301 in the length direction is rotatably arranged on the side of the air guide plate 203 close to the air outlet 101 through a rotating shaft. By rotatably mounting the swing blade body 301 on the air guide plate 203, the distance between the swing blade body 301 and the heater 202 can be shortened, which is conducive to accurately controlling the direction of the warm air.

[0062] In one embodiment, Figures 1 to 4 As shown, the warm air structure further includes a rack 5. The rack 5 is detachably mounted on the warm air housing 1 and is disposed toward the air outlet 101. By mounting the rack 5 on the warm air housing 1, the warm air blown out from the air outlet 101 can be used to dry items. For example, a towel can be placed on the rack 5 to form a towel rack, and the warm air can be used to dry the towel. Alternatively, clothes can be placed on the rack 5 to form a clothes hanger, and the warm air can be used to dry the clothes.

[0063] That is to say, the embodiment of the present application also integrates the warm air function and the drying function into the electric water heater, enriching the functions of the electric water heater and further improving the user experience.

[0064] It should be noted that the detachable manner of the storage rack 5 and the heater housing 1 may be a snap-fit ​​connection structure or a fastener connection structure, and the embodiments of the present application do not impose too many restrictions on this.

[0065] Compared with the fastener-type connection structure, the snap-on connection structure facilitates quick installation and removal. Figure 1 As shown, opposite ends of the storage rack 5 are bent toward the heater housing 1 and are respectively snap-fitted to opposite side surfaces of the heater housing 1 in the length direction through buckles.

[0066] Specifically, two fixing slots are respectively provided at opposite ends of the storage rack 5, and buckles are respectively provided on the opposite side sides of the length direction of the heater housing 1. The installation and fixation of the storage rack 5 are achieved by cooperating between the buckles and the fixing slots. The structure is simple and the use cost is low.

[0067] When the electric water heater uses the warm air function, the rack 5 can be removed from the warm air housing 1 to prevent the rack 5 from obstructing the outlet of warm air, which is convenient to use and beautiful.

[0068] When the electric water heater uses the drying function, the rack 5 is mounted on the heater housing 1 by means of buckles so as to place items that need to be dried.

[0069] According to an embodiment of the present utility model, on the other hand, Figure 1 As shown, an electric water heater is also provided, which mainly comprises: a water heater housing 6 and a warm air structure. The warm air housing 1 is arranged outside the water heater housing 6 .

[0070] The embodiment of the present application is equipped with an electric water heater with the warm air structure, and the direction of the warm air at the air outlet 101 is adjusted by the swing blade mechanism 3. Compared with the existing electric water heaters, it can take into account the heating needs of users of different heights, has better compatibility, improves the heating effect, and provides a good user experience.

[0071] Specifically, the upper end of the heater housing 1 is detachably connected to the lower end of the water heater housing 6 for installation and maintenance. The detachable fixed connection can be a snap-on fixed structure for easy installation, or a fastener-type fixed structure for stable connection. The embodiments of the present application do not impose too many restrictions on this.

[0072] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features 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.

[0073] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. 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. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
