DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0049] Reference Figures 1 to 11As shown, this embodiment provides a bathroom heater. The bathroom heater comprises a box body 1 and an air outlet duct 2 located in the box body 1.

[0050] The box body 1 has an air inlet 121 and an air outlet 100 both connected to the air outlet duct 2, and a wind wheel 3 is arranged in the air outlet duct 2. The box body 1 has a motor installation area 4, and the motor installation area 4 is used to install a DC motor or an AC motor. Both the DC motor 41 and the AC motor 42 can be connected to the wind wheel 3 to drive the wind wheel 3 to rotate.

[0051] Exemplarily, the box body 1 can be connected to the top of the bathroom, and the rotating shaft of the DC motor 41 or the rotating shaft of the AC motor 42 is connected to the wind wheel 3 to provide power to the wind wheel 3, so that the air continuously enters the air outlet duct 2 from the air inlet 121 under the drive of the wind wheel 3, and flows out from the air outlet 100, forming an air flow circulation.

[0052] In specific implementation, an installation structure 511 and a pre-positioning structure 6 are provided at the motor installation area 4. The pre-positioning structure 6 is used to position the motor (one of the DC motor 41 and the AC motor 42) to be installed in the motor installation area 4. The installation structure 511 is used to connect with the motor positioned at the motor installation area 4 to fix the DC motor 41 or the AC motor 42 selectively in the motor installation area 4.

[0053] In other words, the box body 1 can be compatible with installing a DC motor 41 and an AC motor 42, so that the fan wheel 3 of the bathroom heater can be driven by a fixed-frequency AC motor 42 or by a variable-frequency DC motor 41 that can adjust the speed, and the bathroom heater has high applicability.

[0054] The bathroom heater provided in this embodiment is provided with a mounting structure 511 and a pre-positioning structure 6 at the motor mounting area 4 of the housing 1, so that the pre-positioning structure 6 is used to position the motor to be installed at the motor mounting area 4, and the mounting structure 511 is used to connect with the motor positioned at the motor mounting area 4 to fix the DC motor 41 or the AC motor 42 in the motor mounting area 4, so that the wind wheel 3 of the bathroom heater can be driven by the AC motor 42 or the DC motor 41, that is, the bathroom heater can be compatible with the use of the DC motor 41 and the AC motor 42 to drive the wind wheel 3, thereby broadening the different application scenarios of the bathroom heater to a certain extent and improving the applicability of the bathroom heater. At the same time, since the pre-positioning structure 6 is provided on the housing 1, the position of the DC motor 41 or the AC motor 42 on the housing 1 can be pre-positioned to a certain extent before the motor is installed, so that the installation efficiency of the motor can be improved to a certain extent, which is conducive to improving the production efficiency of the entire bathroom heater.

[0055] In some embodiments, reference Figures 1 to 9As shown, there are two wind wheels 3 and two motor installation areas 4, which are arranged one by one. There are two installation structures 511 and two pre-positioning structures 6, and each motor installation area 4 has one installation structure 511 and one pre-positioning structure 6. There are two air outlet ducts 2, and the wind wheels 3 are located in the corresponding air outlet ducts 2.

[0056] In this way, by setting up two air outlet ducts 2 and driving the corresponding wind wheel 3 to rotate through the motor in each motor installation area 4, the different usage requirements of users can be met, so that the application scope of the bathroom heater is improved to a certain extent.

[0057] For example, when there are two motor installation areas 4, a DC motor 41 can be fixed in one of the motor installation areas 4, and an AC motor 42 can be fixed in one of the motor installation areas 4; or a DC motor 41 can be fixed in both motor installation areas 4; or an AC motor 42 can be fixed in both motor installation areas 4, and the specific selection can be arbitrarily made according to actual needs. Among them, the pre-positioning structure 6 in each motor installation area 4 is used to pre-position the motor (DC motor 41 or AC motor 42) pre-installed in the area, and fixedly installed through the installation structure 511 in the area.

[0058] In a specific implementation, the number of the air inlet 121 and the number of the air outlet 100 can be two, and the air outlet duct 2 is arranged in a one-to-one correspondence with the air inlet 121 and the air outlet 100.

[0059] For example, one of the air outlet ducts 2 (referred to as the first air duct, specifically Figure 1 The right side of the figure is the blowing duct, which is used to blow air from the bathroom heater and accelerate the air circulation in the bathroom. The other air outlet duct 2 (called the second air duct, specifically Figure 1 The left side in the figure) is a ventilation duct, and the air outlet 100 of the second duct can be connected to the external space of the bathroom to realize the exhaust of the bathroom heater, remove the turbid air in the bathroom, and ventilate the bathroom.

[0060] Exemplarily, an air outlet assembly 9 can be provided at the outlet end of the air blowing duct, and the air outlet assembly 9 is installed on the box body 1, wherein the air outlet assembly 9 can include a PTC heater with a heating function, or the air outlet assembly 9 can also include a refrigerator with a cooling function, or the air outlet assembly 9 can also only pass air.

[0061] In some embodiments, reference Figures 4 to 9As shown, the mounting structure 511 includes a second mounting hole 5111 disposed on the housing 1. The second mounting hole 5111 is used to correspond to the first mounting hole 4111 on the DC motor 41, so that the DC motor 41 can be fixed in the motor mounting area 4 by a first fastener penetrating through the first mounting hole 4111 and the second mounting hole 5111.

[0062] The mounting structure 511 may further include a second connection hole 5112 disposed on the housing 1. The second connection hole 5112 is used to correspond to the first connection hole 4211 on the AC motor 42, so that the AC motor 42 can be fixed in the motor mounting area 4 by a second fastener penetrating through the first connection hole 4211 and the second connection hole 5112.

[0063] With this arrangement, the installation of the motor on the housing 1 is simple and convenient, and the connection is reliable, which is conducive to improving the stability of the motor installed in the motor installation area 4, thereby improving the rotation stability of the wind wheel 3 to a certain extent, so that the working stability of the bathroom heater is improved. At the same time, when one of the motor and the housing 1 is damaged, the damaged part can be directly replaced, thereby avoiding the scrapping of the motor and the housing 1 as a whole to a certain extent, saving the maintenance and use costs.

[0064] Exemplarily, after the pre-positioning structure 6 pre-positions the DC motor 41, the first mounting hole 4111 is aligned with the second mounting hole 5111. Similarly, after the pre-positioning structure 6 pre-positions the AC motor 42, the first connection hole 4211 and the second connection hole 5112 are aligned.

[0065] Exemplarily, the first fastener and the second fastener may be screws, bolts, etc. Alternatively, in other implementations, the DC motor 41 or the AC motor 42 and the box body 1 may be connected to the box body 1 by means of buckles, etc.

[0066] Reference Figure 4 As shown, the DC motor 41 may include two first mounting seats 411 that are arranged opposite to each other. For example, two first mounting holes 4111 may be provided on each first mounting seat 411 .

[0067] The AC motor 42 may include two second mounting seats 421 that are oppositely disposed. For example, two first connecting holes 4211 may be provided on each of the second mounting seats 421 .

[0068] In some embodiments, reference Figures 4 to 9As shown, two groups of mounting components 5 are provided at the motor mounting area 4. When the mounting structure 511 includes the second mounting hole 5111, one group of mounting components 5 includes at least one mounting protrusion 51 extending along the thickness direction of the box body 1; the second mounting hole 5111 is provided on the mounting protrusion 51 of one group of mounting components 5.

[0069] When the mounting structure 511 includes the second connection hole 5112 , another group of mounting components 5 includes at least one mounting protrusion 51 extending along the thickness direction of the box body 1 , and the second connection hole 5112 is arranged on the mounting protrusion 51 of the other group of mounting components 5 .

[0070] The thickness direction of the box body 1 is specifically Figure 1 , Figure 5 , Figure 7 as well as Figures 9 to 11 Z direction shown.

[0071] This arrangement ensures that the motor can be reliably installed on the box 1 and that the bathroom heater is stable during installation and use. At the same time, it can also avoid the situation where the overall thickness of the box 1 is too thick to a certain extent, thereby facilitating the thinning and lightweight design of the bathroom heater.

[0072] Exemplarily, the mounting protrusion 51 may be a mounting column, a mounting block, or the like.

[0073] Specifically, refer to Figure 5 , Figure 6 and Fig. 9 As shown, when there are two motor mounting areas 4, specifically, two groups of mounting components 5 are provided at each motor mounting area 4, and the second mounting hole 5111 and the second connecting hole 5112 in each motor mounting area 4 for connecting with the motor are both provided on the mounting protrusion 51 of the corresponding mounting component 5.

[0074] In some embodiments, reference Figure 5 , Figure 6 and Fig. 9 As shown, among all the mounting protrusions 51, a reinforcement piece 7 is further arranged between some adjacent two mounting protrusions 51. Such arrangement can improve the structural strength of the mounting protrusions 51 to a certain extent, thereby further improving the reliability and stability of the motor installation on the box body 1.

[0075] For example, refer to Figure 5 , Figure 6 and Fig. 9 As shown, the reinforcement member 7 may be a reinforcement rib, a reinforcement plate, etc.

[0076] Reference Figures 4 to 9As shown, when the DC motor 41 has four first mounting holes 4111 and the AC motor 42 has four first connection holes 4211, the number of mounting protrusions 51 corresponds to eight. The eight mounting protrusions 51 can be evenly divided into two groups along the circumference of the wind wheel 3, and in each group of mounting protrusions 51, a reinforcement member 7 is provided between two adjacent mounting protrusions 51.

[0077] In some embodiments, reference Figure 5 , Figure 6 and Fig. 9 As shown, a reinforcing portion 71 is further provided at the joint of the reinforcing member 7 and the housing 1. This can further improve the structural strength between the reinforcing member 7 and the housing 1, thereby improving the structural strength of the mounting protrusion 51 and effectively ensuring the reliability of the motor installation.

[0078] In some embodiments, the reinforcement member 7, the mounting protrusion 51 and the housing 1 are integrally formed, so that the overall structural strength of the reinforcement member 7, the mounting protrusion 51 and the housing 1 is high, which is beneficial to improving the installation strength of the motor and facilitating subsequent assembly.

[0079] In some embodiments, reference Figure 5 , Figure 6 and Fig. 9 As shown, the joint between the reinforcement member 7 and the box body 1 has a smooth transition, which can avoid stress concentration at the joint between the reinforcement member 7 and the box body 1 to a certain extent, making the structural strength between the reinforcement member 7 and the box body 1 higher.

[0080] In some embodiments, reference Figures 4 to 9 As shown, the pre-positioning structure 6 includes a first pre-positioning member 61 and a second pre-positioning member 62. The first pre-positioning member 61 is used to pre-position the DC motor 41; the second pre-positioning member 62 is used to pre-position the AC motor 42.

[0081] In this way, before the motor is installed, the DC motor 41 can be pre-positioned by the first pre-positioning member 61, or the AC motor 42 can be pre-positioned by the second pre-positioning member 62, so as to ensure the subsequent installation efficiency of the motor.

[0082] In some embodiments, reference Figures 4 to 6 As shown, the DC motor 41 has a first pre-positioning hole 4112 , and the first pre-positioning member 61 includes a pre-positioning column that is arranged on the box body 1 and can extend into the first pre-positioning hole 4112 .

[0083] The DC motor 41 is pre-positioned by the cooperation between the first pre-positioning hole 4112 and the pre-positioning column. This makes the pre-positioning of the DC motor 41 simple and convenient, and facilitates subsequent assembly and connection.

[0084] Of course, in other embodiments, the first pre-positioning member 61 may also be a pre-positioning hole provided on the box body 1 , and a pre-positioning column for the pre-positioning hole to extend into is provided on the DC motor 41 .

[0085] In some embodiments, reference Figure 5 , Figure 6 , Fig. 9 and Fig.10 As shown, the AC motor 42 has a pre-positioning protrusion 425, and the second pre-positioning member 62 at least includes a second pre-positioning hole 621 which is arranged on the box body 1 and into which the pre-positioning protrusion 425 can extend.

[0086] Through the cooperation between the second pre-positioning hole 621 and the pre-positioning protrusion 425, the AC motor 42 is pre-positioned to a certain extent, so that the pre-positioning of the AC motor 42 is simple and convenient, and it is convenient for subsequent assembly and connection.

[0087] In some embodiments, reference Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the second pre-positioning member 62 includes at least a pre-positioning portion 622. There are at least two pre-positioning portions 622, which are arranged on the housing 1 at intervals along the circumference of the AC motor 42 and can abut against the outer circumference of the AC motor 42 to pre-position the AC motor 42 between the pre-positioning portions 622.

[0088] In this way, by providing at least two pre-positioning parts 622 and enabling at least two pre-positioning parts 622 to abut and cooperate with the outer peripheral surface of the AC motor 42, the AC motor 42 is limited between the pre-positioning parts 622 to achieve pre-positioning of the AC motor 42. This makes pre-positioning simple and has a good pre-positioning effect.

[0089] For example, refer to Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, there may be four pre-positioning portions 622 , and the four pre-positioning portions 622 are grouped in pairs, and the two pre-positioning portions 622 in a group are arranged on both sides of the AC motor 42 opposite to each other.

[0090] In some embodiments, reference Figures 1 to 11 As shown, the box body 1 includes a hollow box body 11 and a cover body 12 detachably covered on the box body 11; the air outlet duct 2 is located in the box body 11; the air inlet 121 and at least part of the air outlet 100 are both opened on the cover body 12; and the motor installation area 4 is located on the box body 11.

[0091] In this way, when one of the box body 11 and the cover body 12 is damaged, only one of the box body 11 and the cover body 12 needs to be replaced, which to a certain extent avoids the scrapping of the box body 11 and the cover body 12 as a whole, which is conducive to saving maintenance and use costs.

[0092] The air inlet 121 and the air outlet 100 corresponding to the first air duct are both located on the cover 12, the air inlet 121 corresponding to the second air duct is located on the cover 12, and the air outlet 100 corresponding to the second air duct is located on the box body 11 for exhaust.

[0093] In some embodiments, the installation direction of the DC motor 41 and the AC motor 42 on the box body 11 is the same as the installation direction of the cover 12 on the box body 11 .

[0094] For example, during the production and assembly of the bathroom heater, the DC motor 41 or the AC motor 42 is first installed on the box body 11, and then the cover 12 can be placed on the box body 11. Therefore, through the above arrangement, when the bathroom heater is assembled, the various components are fixed from the same direction as much as possible, which can avoid the situation that the product needs to be turned back and forth for installation during the assembly of the bathroom heater to a certain extent, thereby shortening the assembly time to a certain extent and improving production efficiency.

[0095] In some embodiments, reference Figure 1 , Figure 5 , Fig. 9 and Fig.11 As shown, the outer wall of the box body 1 has a concave cavity 111 which is recessed toward the inner cavity of the box body 1. This can improve the structural strength of the box body 1 to a certain extent, thereby reducing the degree of deformation of the box body 1 such as concave during the entire production process of the bathroom heater, thereby ensuring the aesthetic appearance of the bathroom heater and helping to extend the service life of the bathroom heater.

[0096] In some embodiments, reference Figure 1 , Figure 5 , Fig. 9 and Fig.11 As shown, part of the outer wall of the box body 1 is bent toward the inner cavity of the box body 1 to form the above-mentioned concave cavity 111 on the outer wall of the box body 1 .

[0097] With this arrangement, the cavity 111 is easily formed and the structural strength of the entire box body 1 can be ensured, further preventing the box body 1 from being deformed.

[0098] In some embodiments, reference Figure 1 , Figure 5 , Fig. 9 and Fig.11As shown, the above-mentioned cavity 111 is formed on the outer wall of the box body 11 away from the cover body 12, and the part of the box body 11 without the cavity 111 has an assembly hole 112; the cover body 12 and the box body 11 are detachably connected by at least a third fastener passing through the assembly hole 112.

[0099] This arrangement can shorten the axial length of the assembly hole 112 and the length of the third fastener to a certain extent while ensuring the connection strength between the box body 11 and the cover body 12, and facilitate the opening and forming of the assembly hole 112.

[0100] For example, the box body 11 can be integrally formed by injection molding. In this case, the above arrangement is larger than the assembly hole along the depth direction of the inner cavity of the box body ( Figure 1 , Figure 5 , Figure 7 as well as Figures 9 to 11 The scheme of extending the assembly hole 112 in the Z direction as shown can avoid the situation where the mold is easily broken due to the screw pin being too long when the assembly hole 112 is injection molded on the box body 11, thereby helping to ensure production efficiency and product quality.

[0101] Specifically, a screw column 113 is provided on the box body 11 , and the assembly hole 112 is specifically located on the screw column 113 .

[0102] Illustratively, the third fastener may be a screw, a bolt, or the like.

[0103] For example, the box body 11 and the cover body 12 may be detachably connected by means of a buckle or the like.

[0104] In some embodiments, reference Figure 1 , Figure 3 , Figure 5 and Fig. 9 As shown, a driver 8 is also connected to the inner cavity of the box 1, and the driver 8 can be electrically connected to at least the DC motor 41 or the AC motor 42 to control the working state of the DC motor 41 or the AC motor 42. The working state of the DC motor 41 or the AC motor 42 includes starting work, stopping work, etc.

[0105] Exemplarily, a functional panel (not shown) is also provided on the side of the cover 12 away from the box body 11, and a connecting port is provided at the position of the corresponding air inlet 121 of the functional panel and at least part of the air outlet 100 (specifically, the air outlet 100 corresponding to the first air duct), and a swing leaf that can rotate to change the air outlet direction can be provided at the connecting port corresponding to the part of the air outlet 100 of the functional panel, or a functional detection component such as a temperature sensor can also be provided at the connecting port. Among them, the driver 8 has a functional line 81, and the cover 12 has a wire hole, and the functional line 81 can extend through the wire hole and be plugged and connected with the functional panel to at least power the swing leaf, the functional detection component, etc.

[0106] Exemplarily, the above-mentioned PTC heater or refrigerator etc. may also be electrically connected to the driver 8 .

[0107] In some embodiments, reference Figure 1 , Figure 3 , Figure 5 and Fig. 9 As shown, the box body 11 is also provided with at least a wiring terminal 10 for electrical connection with the mains and the driver 8, the wiring terminal 10 has a wiring port for wiring, and the cover 12 has a notch 122 for exposing the wiring port at the position corresponding to the wiring port. This can avoid the need to flip the box body 11 during the wiring process of the driver 8 and the wiring terminal 10 to a certain extent, thereby improving the convenience of wiring the driver 8 and the wiring port, and further improving the convenience of installing the bathroom heater.

[0108] For example, after the wiring is completed, the connection between the wiring terminal 10 and the mains power supply can be compressed by means of a wire clamp 101 .

[0109] Reference Figure 1 and Figure 2 As shown, a wiring cover 123 is also provided at the notch 122, and the wiring cover 123 is used to cover at least part of the notch 122 to improve the appearance of the bathroom heater. The wiring cover 123 can be connected to at least one of the box body 11 and the cover body 12.

[0110] In some embodiments, reference Figure 1 , Figure 3 , Figure 5 and Fig. 9 As shown, the driver 8 is located beside the wind wheel 3 in the radial direction; the outer contour of the driver 8 is a rectangular parallelepiped structure, and the long side of the driver 8 is arranged perpendicular to the axial direction of the wind wheel 3.

[0111] That is to say, the driver 8 is arranged horizontally in the box 1, which can reduce the thickness of the bathroom heater to a certain extent, so that the bathroom heater can be adapted to more installation environments, such as being installed in bathrooms with a small ceiling space height, thereby improving the applicability of the bathroom heater.

[0112] In specific implementation, the dimensions of the impeller 3 and the air outlet assembly 9 in the thickness direction of the box body 1 can also be made thinner to further reduce the thickness of the bathroom heater. For example, the thickness of the bathroom heater after thinning can be made no greater than 75 mm.

[0113] In some embodiments, reference Figures 4 to 7 As shown, the DC motor 41 includes a first housing 413 and a first rotating shaft 412 that can be inserted into the shaft hole of the wind wheel 3. The first housing 413 is connected to the outside of the first rotating shaft 412 and can rotate synchronously with the first rotating shaft 412. The wind wheel 3 and the first housing 413 are relatively fixed, so that the wind wheel 3 can rotate under the joint action of the first housing 413 and the first rotating shaft 412.

[0114] Since the first housing 413 and the first rotating shaft 412 can simultaneously drive the wind wheel 3 to rotate, this can improve the smooth driving of the wind wheel 3 by the DC motor 41 to a certain extent, and effectively improve the dynamic balancing effect of the wind wheel 3.

[0115] Exemplarily, the DC motor 41 in this embodiment may be an outer rotor motor.

[0116] For example, the wind wheel 3 can be in contact with the axial end surface of the first housing 413, so that the contact area between the wind wheel 3 and the first housing 413 can be increased, thereby further improving the driving effect of the DC motor 41 on the wind wheel 3. In specific implementation, the first housing 413 and the wind wheel 3 can be detachably connected by nuts or the like.

[0117] Reference Figure 4 and Figure 7 As shown, the DC motor 41 further includes a base assembly 414 , for example, the first mounting seat 411 may be disposed on the base assembly 414 .

[0118] In some embodiments, reference Figures 8 to 10 As shown, the AC motor 42 includes a second rotating shaft 422 that can be inserted into the shaft hole of the wind wheel 3 and a second shell 423 located outside the second rotating shaft 422. An isolation member 424 is arranged between the wind wheel 3 and the second shell 423. The isolation member 424 is used to prevent the second shell 423 from rotating synchronously with the wind wheel 3.

[0119] Such an arrangement can ensure stable driving of the wind wheel 3 by the AC motor 42 to a certain extent, and avoid interference of the second housing 423 with the rotation of the wind wheel 3 to a certain extent.

[0120] Exemplarily, the isolation member 424 may be a retaining spring, an isolation plate, or the like.
