HEATING MODULE FOR RECREATIONAL VEHICLES

Abstract

A heating module for recreational vehicles (RVs), including a heat exchanger, a heating water inlet, a heating water outlet and a cold water inlet. The heat exchanger is communicated with the heating water inlet. A side of the heat exchanger is provided with a fan to generate air flow, so as to carry the heat generated by the heat exchanger to an interior of the RV. The heating water inlet is communicated with a water outlet of a water heater. The heating water outlet is connected with the heat exchanger, and a water pump is provided on a pipeline between the heating water outlet and the heat exchanger. The cold water inlet is configured to be connected with tap water or a water storage tank of the RV. A water flow sensor is provided on the cold water inlet.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 schematically shows a structure of a heating module for recreational vehicles according to an embodiment of the present disclosure.

DETAILED DESCRIPTION OF EMBODIMENTS

[0024] The present disclosure will be clearly and completely described below with reference to the embodiments and accompanying drawings. It's obvious that described herein are only some embodiments rather than all embodiments of the disclosure.

[0025] Referring to FIG. 1, the present disclosure provides a heating module for recreational vehicles (RVs), including a heat exchanger 10 and a heating water inlet 4. The heat exchanger 10 is communicated with the heating water inlet 4. A side of the heat exchanger 10 is provided with a fan 2; the fan 2 is configured to generate an air flow to carry heat generated by the heat exchanger 10 into an RV. The heating water inlet 4 is communicated with a water outlet of a vehicle-mounted water heater. The heating module further includes a heating water outlet 5 and a cold water inlet 6. The heating water outlet 5 is connected with the heat exchanger 10, and a water pump 8 is arranged on a pipeline between the heating water outlet 5 and the heat exchanger 10. The cold water inlet 6 is configured to be connected with tap water or a water storage tank of the RV. And a water flow sensor 7 is provided on the cold water inlet 6.

[0026] In an embodiment, the heating module further includes a controller 3. The controller 3 is electrically connected with the fan 2 and the water pump 8. The controller 3 is also electrically connected with a temperature sensor in the RV. And the heating module can realize automatic operation through a connection between the controller 3 and the temperature sensor.

[0027] In an embodiment, a first check valve 1 is arranged on the heating water outlet 5, and a second check valve 9 is arranged on the cold water inlet 6.

[0028] The operation flow during the heating state: the temperature sensor detects that temperature meets a condition for starting the heating.fwdarw.the water pump 8 is started.fwdarw.the water heater detects a water flow signal to start ignition.fwdarw.the fan 2 is started, and the fan 2 continuously sends the hot wind for heating.fwdarw.the temperature sensor detects that the temperature reaches a present value.fwdarw.the water pump 8 and the fan 2 are stopped.

[0029] The operation flow during the showering state: cold water flows through the water flow sensor 7 of the heating module.fwdarw.a water flow signal is detected.fwdarw.the operation of the water pump 8 and the fan 2 are stopped, and the cold water is normally heated through the water heater for showering.

[0030] Referring to FIG. 1, the heating water inlet 4 is connected with a water outlet of the water heater, and the heating water outlet 5 is connected with the water inlet of the water heater. The cold water inlet 6 is connected with the tap water or the water storage tank of the RV. A water flow direction of water in the first check valve 1 and the second check valve 9 is to the heating water outlet 5, and a reverse direction can not flow, so as to effectively avoid backflow of heating and bathroom. The water flow sensor 7 can determine whether there is a demand for domestic hot water, if yes, the water pump 8 and the fan 2 are stopped.

[0031] It can be seen that the heating module provided herein effectively solves the heating problems of the RVs without affecting the normal showering operation, which greatly improves the users' experience.

[0032] It should be noted that the orientation or position relationships indicated by the terms up, down, left, right, front, back and so on are only used to describe the relative positional relationship or movement in a particular attitude (as shown in the accompanying drawings), and if the particular attitude changes, the directional indication accordingly changes.

[0033] Besides, the terms first and second are only used for description, and can't be understood as indicating or implying relative importance, or implying and indicating the number of referred technical features. Therefore, once a feature is defined with first or second, it may expressly or impliedly indicate the presence of one or more of such features. As used herein, multiple means two, three or more unless otherwise clearly stated.

[0034] As used herein, unless otherwise expressly specified and limited, the terms connection, linkage and fixing should be interpreted in a broad sense. For example, it can be fixed connection, removable connection or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium; and it can be internal communication or interaction between two components. For those of ordinary skill in the art, the specific meaning of these terms can be understood in specific cases.

[0035] The technical solutions of individual embodiments of the present disclosure can be combined with each other as long as the combined solution can be implemented by those skilled in the art. When the combination is contradictory or cannot be realized, it shall be considered that such combination does not exist, and is not within the scope of this disclosure defined by the appended claims.
