Description

TECHNICAL FIELD

[0001] The utility model relates to house design technical field, more specifically, it relates to a body washing room. BACKGROUND

[0002] The beach scenic spot or holiday hotel etc. usually is equipped with body washing room, is mainly used for the tourist after the sand on the beach activity washes on the body sand, seawater or sunscreen, promotes the comfort and health of playing. Simple type body washing room is usually equipped with multiple independent compartments or open type shower head, provides cold water washing function, is suitable for tropical or summer use. Upgraded type body washing room is usually equipped with warm water shower, dressing compartment etc., is suitable for four seasons use.

[0003] Considering the problem of protecting privacy, the shower room for body washing usually only opens a small area exhaust or only through the exhaust duct and the outside gas flow, which leads to when the number of people using the shower room at the same time is more or the water temperature is higher, more hot air or water vapor will be gathered in the room, which can easily cause the shower person to have an uncomfortable reaction. At the same time, the dressing compartment and other function rooms require a certain thermal insulation, and the requirements for air flow between the inside and outside are different from the shower room.

[0004] At present, in order to optimize the indoor and outdoor air flow, it is usually necessary to separate the rooms with different functions and equip air handling devices, which increases the complexity of the layout of the body washing room and the cost is difficult to control. UTILITY MODEL CONTENTS

[0005] The utility model aims at overcoming at least one of the defects of the prior art, and provides a body washing room for solving the problem of complicated air convection treatment in the body washing room.

[0006] The utility model takes the technical scheme that a body washing room is provided, which comprises a function room, a first shower room and a first passage, the function room and the first shower room are communicated through the first passage;

[0007] The top of the function room is closed, and the side of the function room is provided with a first function room opening communicated with the first passage;

[0008] The top of the first passage is closed, and the side of the first passage is provided with at least one first passage opening communicated with the outside;

[0009] The top of the first shower room is provided with a first exhaust opening communicated with the outside, the side of the first shower room is provided with a first shower room opening communicated with the first passage, and the inside of the first shower room is provided with a first main hot water pipeline.

[0010] In the scheme, the first passage opening is arranged at a low position relative to the first exhaust port, and an air flow channel is automatically formed between the first passage opening and the first exhaust port when the temperature in the first shower room increases relative to the outdoor temperature. Specifically, external cold air enters the first passage through the first passage opening, and then enters the first shower room through the first shower room opening. The cold air has a large density relative to hot air, and diffuses along the bottom surface of the first shower room, forming a horizontal laminar flow. At the same time, the hot air in the first shower room is gathered to the top of the first shower room under the action of buoyancy and is discharged to the outdoor through the first exhaust port. Since the first main hot water pipeline is arranged in the first shower room, the temperature difference between the indoor and outdoor is increased, and the convection efficiency between the first passage opening and the first exhaust port is enhanced, thereby achieving the purpose of solving the poor air flow between the indoor and outdoor of the shower room. In addition, the top of the functional room is closed, and the hot air in the interior of the functional room is gathered at the top after floating up. Since the top lacks an outlet channel, the discharge of the hot air is blocked, and part of the hot air can diffuse to the interior of the functional room again. The hot air flowing out of the first functional room through the first functional room opening is hindered by the cold air flowing in through the first passage opening. In this way, the heat loss in the changing room can be reduced, and the changing or other activities requiring heat preservation can be satisfied. The scheme only improves the physical structure of the first passage opening, the first exhaust port, and the functional room and the first shower room, which is sufficient to improve the air flow rate of the first shower room, while the functional room maintains a certain heat preservation performance, effectively solving the problem of complicated air convection treatment in the shower room.

[0011] In some embodiments, the area of the side of the first shower room other than the first shower room opening is arranged in a closed manner.

[0012] The scheme can avoid air leakage from other ways in the first shower room to the outdoor, and help to build a stable cold and hot air exchange flow channel between the first passage opening and the first exhaust port, and improve the air convection rate.

[0013] In some embodiments, a plurality of first shower rooms are arranged around the interior of the first shower room, and a shower branch pipe in communication with the first main hot water pipeline is arranged in each first shower room. The top of each first shower room is communicated with the first exhaust port.

[0014] In the scheme, the hot air generated in the first shower room directly converges to the top of the first shower room after floating up, and then flows out of the outdoor from the first exhaust port, thereby reducing the flow path length between the first shower room and the first exhaust port and improving the air convection rate between the indoor and outdoor.

[0015] In some embodiments, each first shower room comprises a first partition and a second partition connected to the inner wall of the first shower room, respectively. The first partition and the second partition are arranged in an "eight" shape and jointly enclose the inner space of the first shower room with the inner wall of the first shower room.

[0016] The narrow opening of the "eight" shape is away from the inner wall of the first shower room and communicates with the first shower room opening.

[0017] In this scheme, the first shower room has a narrow opening, which helps to protect the privacy of the shower person. After the external cold air passes through the first shower room opening, it enters the first shower room through the narrow opening, thereby driving the hot air to float upwards. The structure of the first shower room is simple, and a stable internal and external air flow channel can be established between the first passage opening, the first shower room and the first exhaust port.

[0018] In some embodiments, the first exhaust port is located outside the first shower room.

[0019] This scheme can reduce the internal space of the first shower room that can be seen through the first exhaust port from the outside, and improve the privacy protection of the shower person.

[0020] In some embodiments, the first shower room has a first arch structure, and the first exhaust port is arranged at the top center of the first shower room.

[0021] The inner surface of the first shower room of this scheme has a curved surface structure, and the vertex of the curved surface is located at the top center. In this way, by arranging the first exhaust port at the top center, the exhaust port is located at the highest point, which maximizes the use of height difference, helps to build a significant pressure difference in the first shower room, and improves the guiding efficiency of hot air and the convection rate of internal and external air.

[0022] In some embodiments, the first shower room has a semispherical structure, and the first exhaust port is circular.

[0023] The inner surface of the first shower room of this scheme has a curved surface with uniform curvature, which can reduce airflow dead angles, concentrate the rising path of hot air, and clearly separate cold and hot air, thereby enhancing the convection efficiency.

[0024] In some embodiments, the functional room has a second arch structure.

[0025] This scheme can on the one hand promote the rate of hot air gathering in the functional room to the center of the dome of the second arch structure, and on the other hand promote the gathered hot air to diffuse to the functional room through the uniform curved surface of the inner surface of the second arch structure, so that the temperature in the functional room is uniform.

[0026] In some embodiments, it further comprises a second shower room and a second passage, the second shower room communicates with the functional room through the second passage;

[0027] The side of the functional room is provided with a second functional room opening communicating with the second passage.

[0028] The top of the second passageway is closed, and the side of the second passageway is provided with at least one second passageway opening communicating with the outside;

[0029] The top of the second shower room is provided with a second exhaust opening communicating with the outside, the side of the second shower room is provided with a second shower room opening communicating with the second passageway, and the inside of the second shower room is provided with a second main hot water pipeline.

[0030] In some embodiments, the first function room opening and the second function room opening are oppositely arranged, and the area of the side of the function room other than the first function room opening and the second function room opening is closed.

[0031] In this scheme, the function room communicates with the corresponding passageway only through the first function room opening and the second function room opening. Since the first function room opening and the second function room opening are symmetrically arranged, the air flow shows weak stratified exchange, hot air slowly overflows from the upper part of the opening, and cold air seeps from the lower part. In this way, the heat loss inside the function room is slow, and the heat preservation performance can be improved.

[0032] In some embodiments, the first passageway opening and the second passageway opening are arranged on the same side.

[0033] In this scheme, the temperature, air pressure and other differences of the cold air in the first passageway and the second passageway can be reduced, so that the air parameters of the first function room opening and the second function room opening have high consistency, which helps to slow down the heat loss rate inside the function room. On the other hand, the cold and hot air flow channels between the first passageway opening and the first exhaust opening, and the cold and hot air flow channels between the second passageway opening and the second exhaust opening have better stability, which can promote the air flow rate of the first shower room and the second shower room.

[0034] Compared with the prior art, the beneficial effects of the utility model are that: based on the passageway opening, the exhaust opening and the physical structure improvement of the function room and the shower room, the air flow rate of the shower room can be improved, the heat preservation performance of the function room is maintained, and the problem of complicated air convection treatment of the shower room is solved; by adopting the arched structure of the shower room, the circular exhaust opening is arranged on the arched top, and the shower room is constructed based on the partition plate arranged in the shape of eight characters, the air guiding rate in the shower room is further improved, and the privacy protection for the shower person is improved.

[0045] Embodiment 1

[0046] As shown in Figures 1-2 The present embodiment provides a shower room, which comprises a function room 100, a first shower room 200 and a first passage 300, the function room 100 and the first shower room 200 are communicated through the first passage 300;

[0047] The top of the function room 100 is closed, and the side of the function room 100 is provided with a first function room opening 110 communicated with the first passage 300;

[0048] The top of the first passage 300 is closed, and the side of the first passage 300 is provided with at least one first passage opening 310 communicated with the outside;

[0049] The top of the first shower room 200 is provided with a first exhaust port 220 communicated with the outside, the side of the first shower room 200 is provided with a first shower room opening 210 communicated with the first passage 300, and the inside of the first shower room 200 is provided with a first main hot water pipeline. In specific implementation, the function room 100 can be used for changing clothes or set to be a sauna room and the like which requires constant temperature.

[0050] The first passageway opening 310 is specifically the main entrance of the shower room, and it can be understood that the first passageway opening 310 is usually close to the ground and significantly lower than the first exhaust port 220. When the shower in the first shower room 200 is started, hot air is gathered, and the temperature in the first shower room 200 is significantly higher than the outside air. An air flow channel is automatically formed between the first passageway opening 310 and the first exhaust port 220. Specifically, the external cold air enters the first passageway 300 through the first passageway opening 310, and then enters the first shower room 200 through the first shower room opening 210. The cold air has a large density relative to the hot air, and diffuses along the bottom surface of the first shower room 200, forming a horizontal laminar flow. At the same time, the hot air in the first shower room 200 is gathered to the top of the first shower room 200 under the action of buoyancy and is discharged to the outside through the first exhaust port 220. Since the first main hot water pipeline is arranged in the first shower room 200, the temperature difference between the inside and outside of the room is increased, and the convection efficiency between the first passageway opening 310 and the first exhaust port 220 is enhanced, so that the purpose of solving the poor air flow between the inside and outside of the shower room is achieved. At the same time, since the top of the functional room 100 is closed, the hot air in the functional room 100 is gathered at the top after floating up. Therefore, most of the hot air is diffused to the inside space of the functional room 100 by reducing the side opening. Although a part of the hot air has a tendency to flow out to the first passageway 300 through the first functional room opening 110, the cold air flowing into the first functional room opening 110 through the first passageway opening 310 hinders the part of the hot air. Therefore, the heat loss in the changing room can be reduced. As can be seen, the physical structure of the functional room 100 and the first shower room 200 is improved based on the first passageway opening 310 and the first exhaust port 220, so as to promote the air flow rate of the first shower room 200 and ensure the heat preservation performance of the functional room 100, and effectively solve the problem of complicated air convection treatment in the shower room.

[0051] With reference to the foregoing Figure 2 , in order to improve the conduction efficiency of external cold air in the shower room, the first passageway 300 adopts a straight channel design, and the two ends of the first passageway 300 in the length direction are connected with the first shower room opening 210 and the first functional room opening 110 respectively. Therefore, the straight flow path is formed between the external cold air entering through the first passageway opening 310 and the first shower room opening 210 or the first functional room opening 110, so as to shorten the travel distance and avoid air flow disturbance at the corner, thereby improving the air convection efficiency of the shower room and promoting the rapid establishment of relatively balanced air pressure in the first functional room opening 110, so as to achieve the purpose of heat preservation.

[0052] As Figures 1-2As shown, the side of the first shower room 200 is closed except for the first shower room opening 210, that is, the side of the first shower room 200 is indirectly connected with the outside only through the first shower room opening 210, so that air in the first shower room 200 can be prevented from leaking to the outside through other ways, and a stable cold and hot air exchange flow channel can be built between the first passage opening 310 and the first exhaust opening 220, and the air convection rate inside and outside the room is improved.

[0053] With reference to Figure 3 The first shower room 200 is internally provided with a plurality of first shower rooms 230, each of which is provided with a shower branch pipe connected with the first main hot water pipe, and the top of each first shower room 230 is communicated with the first exhaust opening 220. Specifically, the top of each first shower room 230 is provided with an opening communicated with the first exhaust opening 220. During showering, hot air generated in the first shower room 230 directly converges to the top of the first shower room 200 through the opening in the top of the first shower room 230, and then flows out of the room through the first exhaust opening 220, thereby shortening the flow path between the first shower room 230 and the first exhaust opening 220 and improving the air convection rate inside and outside the room.

[0054] With reference to Figure 3 Each first shower room 230 comprises a first partition 231 and a second partition 232 connected with the inner wall of the first shower room 200, respectively. The first partition 231 and the second partition 232 are arranged in an "eight" shape and jointly enclose the inner space of the first shower room 230 with the inner wall of the first shower room 200. The narrow opening of the "eight" shape is away from the inner wall of the first shower room 200 and communicated with the first shower room opening 210. Based on the narrow opening of the "eight" shape, the first partition 231 and the second partition 232 can better shield the inside of the first shower room 200, which helps to protect the privacy of the shower person. After the external cold air enters the first shower room 230 through the first shower room opening 210, the cold air drives the hot air to float up. The structure of the first shower room 230 is simple, and a stable air flow channel between the first passage opening 310, the first shower room 230 and the first exhaust opening 220 can be established.

[0055] With reference to Figure 4 The orthographic projection of the first exhaust opening 220 on the bottom surface of the first shower room 200 is located outside the first shower room 230. In this way, the inside space of the first shower room 230 can be reduced to be observed from the outside through the first exhaust opening 220, and the privacy protection of the shower person is improved. In addition, a straight hot air rising channel is formed in the vertical direction in the center of the first shower room 200, which helps the hot air to quickly rise to the first exhaust opening.

[0056] With reference to Figures 1-3In some embodiments, the first shower room 200 is in a first arched structure, and the first air outlet 220 is arranged at the top center of the first shower room 200. It can be understood that the inner surface of the arched structure has a curved surface structure, and the vertex of the curved surface is located at the top center. Thus, by arranging the first air outlet 220 at the top center, the air outlet is located at the highest point, which maximizes the use of the height difference, helps to build a significant pressure difference in the first shower room 200, improves the guiding efficiency of hot air, and improves the convection rate of the internal and external air.

[0057] With reference to the foregoing Figures 1-2 , in a preferred embodiment, the first shower room 200 is in a semispherical structure, and the first air outlet 220 is arranged in a circular shape. At this time, the inner surface of the first shower room 200 is in a curved surface with uniform curvature, which can reduce the dead angle of airflow, concentrate the upward path of hot air, and obviously stratify the cold and hot air, thereby enhancing the convection efficiency.

[0058] In some embodiments, the functional room 100 is in a second arched structure. On the one hand, the arched structure can promote the rate of hot air gathering in the functional room 100 to the center of the dome. On the other hand, the arched structure can also promote the diffusion of the gathered hot air to the functional room 100 through the uniform curved surface of the inner surface of the second arched structure, so that the temperature in the functional room 100 is uniform.

[0059] In addition, with reference to the foregoing Figure 1 , 3 In order to achieve lighting and aesthetic appearance, in some embodiments, the first shower room 200, the functional room 100, and the first passageway 300 are respectively provided with a plurality of assembly openings at the side portions thereof, and light-transmitting pieces 600 are assembled on the assembly openings. Specifically, light-transmitting glass can be used. In order to protect privacy, the functional room 100 and the first shower room 200 are provided with one-way glass.

[0060] In some embodiments, a shielding device can also be arranged on the first air outlet 220. The shielding device is used to adjust the opening degree of the first air outlet 220, so as to flexibly adjust the gas convection between the inside and outside of the first shower room 200, and improve the comfort of the shower person.

[0061] Embodiment 2

[0062] With reference to the foregoing Figures 5-6 In some embodiments, the space of the functional room 100 is large. In order to improve the utilization rate, on the basis of the shower room in Embodiment 1, a second shower room 400 and a second passageway 500 are further arranged. The second shower room 400 communicates with the functional room 100 through the second passageway 500.

[0063] The side portion of the functional room 100 is provided with a second functional room opening 120 which communicates with the second passageway 500.

[0064] The top of the second passageway 500 is closed, and the side of the second passageway 500 is provided with at least one second passageway opening 510 which is in communication with the outside;

[0065] The top of the second shower room 400 is provided with a second exhaust opening 420 which is in communication with the outside, the side of the second shower room 400 is provided with a second shower room opening 410 which is in communication with the second passageway 500, and the inside of the second shower room 400 is provided with a second main hot water pipeline.

[0066] In addition, similar to the arrangement of the first shower room 200, a plurality of second shower rooms are arranged at intervals around the inside of the second shower room 400, each of the second shower rooms is provided with a shower branch pipeline which is in communication with the second main hot water pipeline, and the top of each of the second shower rooms is in communication with the second exhaust opening 420. In order to improve the air flow rate, the second shower room 400 has a third arched structure, and the second exhaust opening 420 is arranged at the top center of the arched structure.

[0067] With reference to Figure 6 , the first function room opening 110 and the second function room opening 120 are arranged opposite to each other, and the area of the side of the function room 100 other than the first function room opening 110 and the second function room opening 120 is arranged in a closed manner, that is, the function room 100 is indirectly communicated with the outside only through the first function room opening 110 and the second function room opening 120. Since the first function room opening 110 and the second function room opening 120 are symmetrically arranged, the air flow shows weak stratified exchange, hot air slowly overflows through the upper part of the opening, and cold air seeps from the lower part. In this way, the heat loss inside the function room 100 is slow, and the heat preservation performance can be improved. In addition, when this arrangement is adopted, the first passageway 300 and the second passageway 500 are located on the two sides of the function room 100, and the first shower room 200 and the second shower room 400 are also respectively located on the two sides of the function room 100. The whole shower room has a symmetrical structure, and the gas flow between the two openings of the function room 100 is more easily balanced to make the inside of the function room 100 have better heat preservation performance.

[0068] With reference to Figure 6 , the first passageway opening 310 and the second passageway opening 510 are arranged on the same side, so that the temperature, air pressure and other differences of the cold air in the first passageway 300 and the second passageway 500 can be reduced. Therefore, the air parameters of the first function room opening 110 and the second function room opening 120 have high consistency, which helps to slow down the heat loss rate inside the function room 100. On the other hand, the cold and hot air flow passages between the first passageway opening 310 and the first exhaust opening 220, and between the second passageway opening 510 and the second exhaust opening 420 have better stability, which can promote the air flow rate of the first shower room 200 and the second shower room 400.

[0069] In addition, with reference toFigure 5 In order to light and beauty, in some embodiments, the second shower room 400 and the second passageway 500 are respectively provided with several assembly openings at the side thereof, and light-transmitting pieces 600, specifically light-transmitting glass, are assembled on the assembly openings. In order to protect privacy, the second shower room 400 is assembled with one-way glass.

[0070] In some embodiments, the second exhaust port 420 is also provided with a shielding device for adjusting the opening degree of the second exhaust port 420, so as to flexibly adjust the gas convection between the inside and outside of the second shower room 400, and improve the comfort of the shower person.
